Authors: Murguia Danny , Chen Qian , Van Vuuren Tercia Jansen , Rathnayake Asitha , Vilde Vladimir , Middleton Campbell
Published: December 2022

Performance measurement in construction has been a topic of academic and industry inquiry in the UK since the 1990s. Despite the time elapsed, there is little evidence of a consistent industry-wide performance framework that drives decision-making and supports consistent measurement of performance on construction projects. A review of academic advancements and industry practices has been conducted to understand performance measurement in the construction industry, including the metrics assessed, processes for collecting and analysing data, and current limitations. The adoption of digital technologies on construction projects can support timely measurement of performance metrics, allowing for feedback and corrective action to improve performance. However, organisations struggle to connect the top-down measurement value with the bottom-up data capture technologies. The study of an exemplar commercial project was used to inductively develop a data-to-dashboard strategy that supports decision making in construction. The proposed strategy aligns performance metrics, digital tools and processes, and data analysis techniques in a consistent approach to interpret performance-related data and understand key issues. The development and review of the strategy on a live construction project highlights the challenges experienced with multi-source data integration and the translation of information into knowledge that drives decisions and deployment of timely corrective measures. The application of the strategy would ensure a consistent definition of metrics early in the project, and the continuous measurement of leading indicators. Future research will review the proposed strategy on further case study projects and develop an industry-wide multi-level performance measurement framework that uses the proposed strategy to improve performance.

Authors: Xie X , Moretti N , Merino J , Chang J Y , Pauwels P , Parlikad A K
Published: December 2022

The emergence of the digital twin concept can potentially change the way people manage built assets thoroughly. This is because the semantics-based model and linked data approach behind the digital twin, as the successor of classical BIM, provide strong capability in integrating data from fragmented and heterogeneous sources and thus enable better-informed decision-making. Taking buildings as the case, this paper demonstrates the ontology-based Information Management Framework and elaborates on the process to integrate data through a common data model. Specifically, the Foundation Data Model (FDM) representing the operation of buildings and embedded systems is developed and two patterns of integration architecture are compared. To conceptualise all the essential entities and relationships, the building topology ontology and BRICK ontology are reused and merged to serve as a feasible FDM. According to the characteristic of asset management services that digital twins support, two integration architectures are compared, including the data warehouse approach and the mediator approach. A case study is presented to elaborate on the implementation of these two approaches and their applicability. This work sets out the standardised and modularised paradigms for discovering, fetching, and integrating data from disparate sources with different data curation manners.
Exploring quality issues in building information models via structural design reviews
Authors: Candir E , Atasoy G
Published: December 2022

Building Information Models (BIMs) are being used widely in the construction industry. BIMs generally contain errors and mistakes, if not identified, might result in long review processes with the employers or cause issues during code compliance checks or construction. Since the quality requirements vary according to projects and even the stakeholders within the same project, it is challenging to establish a standard quality-check procedure. To focus on the model quality, custom procedures tailored according to the needs of the design teams should be prepared. Hence, there is a need to explore the BIM quality issues and develop formulations to identify and eliminate them in time. Currently, there are no specific guidelines and formulations to determine the overall quality level of a BIM and propose Quality Assurance (QA) and Quality Control (QC) procedures. In this study, design and model reviews from the owner are used to analyze the items to be checked for satisfying a structural model’s integrity. The design reviews are classified and analyzed to understand the existing issues. This study contributes to a better understanding of BIM quality issues and proposes a direction toward BIM quality assurance and control formulation that can be tailored by practitioners and design teams.
Challenges in developing a holistic Whole Building Life Cycle Assessment (WBLCA) software tool: developers’ goals
Authors: Sartori T , Drogemuller R , Omrani S , Lamari F
Published: December 2022

The Intergovernmental Panel on Climate Change (IPCC) recently released a report emphasizing the importance of reducing carbon emissions, indicating that the construction industry is a key player in this process. Whole Building Life Cycle Assessment (WBLCA) is the most efficient method for evaluating buildings’ environmental impacts. It considers the effects of energy consumption during operation and the environmental impacts of extracting, manufacturing, transporting, assembling, and maintaining the building’s components. However, numerous obstacles prevent WBLCA from being fully applied by decision-makers during the building project process (BPP). This paper discusses and suggests improvements to the challenges of integrating WBLCA and BPP. An online survey was performed with nine WBLCA software developers worldwide, examining the critical challenges and how to overcome them. Most participants agreed that increasing WBLCA demand is the most pressing issue. It would encourage the entire construction sector to adopt a life-cycle mindset, pushing WBLCA software developers to improve software tool integration with the BPP. Results from this study will assist software companies and policymakers develop tools and regulations more aligned with the interests of designers.
Enhancing the resilience of low-income housing using emerging digital technologies
Authors: Obonyo E A , Ouma L A
Published: December 2022

The research discussed is part of a Belmont Forum disaster risk reduction project aimed at enhancing the resilience of low-income housing. This paper examines feasibility and viability of using emerging digital technologies to enhance the resilience of low-income housing based on requirements of resource constrained, low-lying coastal areas in East Africa. The authors focus on the need to facilitate data and knowledge sharing across domains to: 1) reduce or avoid the potential property loss from flooding events through mapping the interdependencies and interconnectedness across natural and human systems; 2) coordinate the provision of temporary shelter for displaced victims, and 3) building (back) better during the recovery phase. The deployment of Artificial Intelligence, Internet of Things, BIM, Digital twin, VR/AR in disaster risk management is still an emerging area of research. In general, cutting-edge digital technologies are deployed as standalone solutions to address existing data and knowledge sharing needs that are unique to a sub-group of stakeholders. A more holistic and comprehensive solution will require an integrative framework that supports the seamless flow of information across the stakeholders. We propose to address this need through an artificial intelligence enhanced data, information and knowledge sharing platform that synthesizes content into actionable insights

Published: December 2022

The use of new Key Technological Developments to transform the way Occupational Safety and Health is managed is now becoming a viable option for contractors to consider. These developments can be used to modify the traditional approaches to Occupational Safety and Health to minimize the risks and costs associated with accidents at work and occupational diseases. The research reported in this paper aims to examine the benefits, barriers and challenges associated with the introduction of new digital information technologies in Occupational Safety and Health settings. A longitudinal case study of a complex construction project based in the United Kingdom is reported, which will be used to identify practical solutions and guidelines that can assist organisations in the adoption of these technologies. The lessons learned, both positive and negative, from this project are shared to provide valuable insights to the wider construction industry. The main focus is in the following areas: training; risks identification; site planning. The results of the study can be used to optimise how Health and Safety risks are managed in non-United Kingdom construction projects. The main benefits from this is the resulting productivity gains which can improve project outcomes significantly.

Published: December 2022

The market of smart building solutions aiming at improving the comfort, well-being and health of occupants, but also the inclusiveness and accessibility of the building to people with more specific needs is growing. More and more smart solutions, as well as standards, certifications and public regulations are currently being developed, but a more global and systemic approach seems to be missing. The paper reviews the status of research related to the means and methods enabling interactions with occupants in smart buildings, which feeds an iterative approach with European industry and research actors aiming at collectively identify barriers and opportunities in this area.
Integration of blockchain with emerging technologies in AEC industry: Merits and challenges
Authors: Gupta Purva , Jha Kumar Neeraj
Published: December 2022

While in the last decade, digital tools and technologies have made their way into the construction industry, digital growth is still slow and incremental. The challenge is the consequential need for a collaborative and trustworthy environment with cooperation and concurrence among stakeholders. Blockchain technology holds promise and potential in providing this environment, infusing transparency and security in the mix. This study is thus motivated to explore the emerging information and communication technologies (ICT) in the architecture, engineering, and construction (AEC) industry and their integration with blockchain technology. Greater amounts of real-time digital information and automated systems with the security and transparency of blockchain could be a game-changer in planning and executing construction projects. It will affect not just the decision-makers at the top managerial level but will assist individuals down the line on-field to make decisions based on real-time data available to them.
Analyzing the impact of simulation fidelity on VR-enabled hazard detection on construction sites – A case study on crane lift operation
Authors: Jiang Tanghan , Goh Jiantsen , Xu Zheng , Zheng Nan , Fang Yihai
Published: December 2022

Crane operator training is an essential part of construction safety and is attracting extensive attention from researchers worldwide. Virtual reality (VR) is considered an effective tool to improve training outcomes by providing users with an immersive, risk-free experience in various environments. However, previous VR-based training platforms mainly focused on the scenario and task design; few studies attempted to investigate the impact of simulation fidelity on training efficiency. This research aims to explore the effect of simulation fidelity on training outcomes by comparing user performance in two scenarios. A typical construction site was modelled in a game engine using two rendering approaches; an eye-tracking system was adopted for data collection. The results from a subject experiment indicated the high efficiency of VR in operator safety training and demonstrated the usefulness of eye-tracking in measuring hazard detection performance. Findings showed that a higher level of simulation fidelity might not significantly improve the training efficiency, especially in hazard detection aspects.
Neural Semantic Parsing of Building Regulations for Compliance Checking
Authors: Fuchs S , Witbrock M , Dimyadi J , Amor R
Published: December 2022

Computerising building regulations to allow reasoning is one of the main challenges in automated compliance checking in the built environment. While there has been a long history of translating regulations manually, in recent years, natural language processing (NLP) has been used to support or automate this task. While rule- and ontology-based information extraction and transformation approaches have achieved accurate translations for narrow domains and specific regulation types, machine learning (ML) promises increased scalability and adaptability to new regulation styles. Since ML usually requires many annotated examples as training data, we take advantage of the long history of building code computerisation and use a corpus of manually translated regulations to train a transformer-based encoder-decoder model. Given a relatively small corpus, the model learns to predict the logical structure and extracts entities and relations reasonably well. While the translation quality is not adequate to fully automate the process, the model shows the potential to serve as an auto-completion system and to identify manually translated regulations that need to be reviewed.

Authors: Landry Jean-Francois , McArthur J. J. , Genkin Mikhail , Mokhtari Karim El
Published: December 2022

Heat recovery chiller systems have significant strategic value to reduce building greenhouse gas emissions although this potential remains unrealized in practice. Real-time optimization using model-free reinforcement learning provides a potential solution to this challenge. A full-scale case study to implement reinforcement learning in a 6,000 m2 academic laboratory is planned. This paper presents the methodology used to translate historical data correlations and expert input from operations personnel into the development of the reinforcement learning agent and associated reward function. This approach will permit a more stable and robust implementation of model-free reinforcement learning and the methodology presented will allow operator-identified constraints to be translated into reward functions more broadly, allowing for generalization to similar heat recovery chiller systems.
Implementation of integrated BIM-VR into construction management curriculum: lessons learned and development of a decision support system
Authors: Abbasnejad Behzad , Aranda-Mena Guillermo , Nasirian Araz , Wong Peter SP , Ahankoob Alireza
Published: December 2022

Several educational institutions and universities have introduced Building Information Modelling (BIM) and Virtual Reality (VR) courses separately in the construction management (CM) programs around the globe, and others are in the process of integrating them into their curricula. However, fewer institutions have included integrated BIM and VR into their courses. The industry needs for integrated BIM-VR are not fully recognised by universities due to the lack of a guideline and cognitive dissonance between academia and industry. As a result, most universities do not have a rigorous strategy for developing BIM-VR teaching topics and plans. This study firstly aims to report on some of the employed processes by university lecturers and academics in an Australian University to integrate BIM-VR education into CM curriculum. The review on the secondary sources indicates that the integration of BIM/VR education requires the consideration of three aspects including: industry needs, course contents, classroom size and software and hardware selection. The second aim of this paper is to develop a decision support system by utilising the PROMETHEE method as one of the multi-criteria decision-making approaches. The findings of the secondary sources and development of the decision support system help the educational institutions and practitioners for their future BIM-VR implementation initiatives.
Building cost database for South Africa – key data trends and implications
Authors: Windapo Abimbola
Published: December 2022

The accuracy of any projections depends on the comprehensiveness of the report and the ability to gather appropriate data for the study. Inaccurate portrayals of any study will misguide the investor and result in project failure and loss of resources. Due to the current depressed state of the South African Economy, the construction industry’s value fell sharply and there was significant job loss. To help economic recovery, the South African government announced a ten-year infrastructure investment plan in housing among other sectors. The considerable deficit in infrastructure and housing in South Africa means that changes in building costs are important because of the implications of changes to affordability. This paper examines the trends in building costs in South Africa over five years and reconciles these indicators with other key socio-economic factors. The study analysed the indicators of Building Cost in the Medium-Term Forecasting Associates (MFA), Department Trade and Industry (DTi), and StatsSA database using descriptive and inferential statistics. The findings suggest a positive correlation between population growth, unemployment, poverty, and the growth in building costs. While it can be inferred that inflation and corruption have a negative impact on growth in building cost. The study recommends that investors should plan ahead and make projections on population, unemployment, and poverty to avoid project failure and loss of resources due to increased building costs.
Managing the risks associated with remote learning project implementation
Authors: Aranda-Mena Guillermo , Vaz-Serra Paulo , Edwards Peter
Published: December 2022

Academic institutions have faced substantial issues and difficulties since the novel coronavirus disease became pandemic. Traditional class attendance-based pedagogy rapidly became compromised, and universities were forced into alternative ways of delivering learning to students who themselves faced restrictions, even to the point of not even being able to enter the countries where they had enrolled for their studies. In the haste to implement projects for alternative learning delivery systems, there was little time to develop proactive approaches to project risk management for such implementation. By default, delivery risks were addressed re-actively, and a “lessons learned” post-implementation approach prevailed. Two case studies have been used to explore risk management practices used in alternative learning delivery environments. The findings show emerging teaching and learning dynamics in parallel with risk-managing delivery of course learning experience and content quality.

Published: December 2022

Innovation of a firm is considered the firm’s ability to develop a new or improved product and processes or equipment for the creation and production of new invention. While customers or clients are essential to the realisation and success of innovation in construction firms. However, there is deprived understanding of the impacts of construction firms’ innovation on customers /clients. This paper, hence, exploratively determine the impacts of construction micro, small and medium enterprises’ (CMSMEs) innovation on customers/clients. To achieve this the research employed qualitative research method to exploratively determine the effects of innovation on construction micro, small and medium enterprises’ (CMSMEs) clients. While recorded semi-structured interview with opened ended questions were utilized to gather information from 43 innovative CMSMEs through judgemental and snowballing examining procedure. Information gathered were, open and axial coded, examined and interpreted. The outcome from the study reveal that innovation predominantly impacts on client/customer satisfaction, client/customer retention and client/customer relations. In addition, the findings also indicate minor occurrences of innovation impacting clients’/customers’ value for creativity, clients’/customers’ value for money and after sales services to clients’/customers. This outcome implies that innovation could be postulated as a driver of client satisfaction of a firm resulting in improved client retention and ultimately, the success of the firm. The search improves body of knowledge in respect of the basic effects of innovations on construction firm clients.
A survey on BIM information management: the approach of producers and consumers of model information in Brazil
Authors: Oliveira F M , Santos E T
Published: December 2022

BIM Information Management, namely how information is introduced in and consumed from building information models, have an impact on the efficacy and efficiency of BIM workflows. Implicit reliance on all the information contained in a model may result in non-value-adding work from model authors. The recommended alternative is creation and use of information according to the Project BIM Execution Plan specifications. Regardless the adopted approach, model asseveration is demanded from authors (i.e., the verification that all required information is reliable and is available on a released model). International standards, such as ISO 19650, require clear and rigorous specification of information need, but anecdotal evidence indicates that the current practices in local markets are far from those recommended by these standards. An extensive online survey was conducted to assess current practices of professionals from the Brazilian market. Results showed that about half of the respondents adopt document-based (MEA/MET) recommended practices when dealing with model information, while the other half kept a behaviour more akin to the older CAD workflows. The implicit reliance (without checking MEA/MET documents) on model information varies according to professional role, being lower for design professionals and coordinators and higher for construction managers. As standards evolve and introduce new concepts for deeper and more granular information management, such as the Level of Information Need, it is necessary that professionals adapt their practices for increased efficiency on their BIM workflows.

Authors: Wong James , Hoong Peng , Teo Evelyn , Lin Ai
Published: December 2022

There have been numerous research studies on understanding buildings better and finding ways to improve water and energy consumption while making them more comfortable for occupants. With technologies such as Building Automation Systems, IoT devices, mobile applications and BIM software, more data can be generated and stored for intelligence and more effective facility management. The next big thing is the digital twin concept, where a virtual model is created from the physical building that brings together real-time information from all data capture devices, allows monitoring, historical analysis, predictive analytics, and simulation as well as interaction and intervention to be carried out. Many research studies have covered the characteristics, architecture, and benefits of digital twins and examined the potential implementation issues. However, the literature on evaluating return on investment (ROI) and acceptance of digital twins for the built environment at the individual user level is limited. This study aims to develop a conceptual model to examine the motivational intent and behavioural choice by individual users to utilise the digital twin technology to improve their performance. The objectives of this study are to examine technology acceptance theories and develop a conceptual model that measures the relationship between the tasks involved and the digital twin technology characteristics.
A Common Configurator Framework for Distributed Design, Collaboration and Verification Across the Full AEC Supply Chain
Authors: Al Fisher  , Tsakiridis Georgios , Lombardi Alessio , Ahmad Maz , Watts Andy
Published: December 2022

The wider AEC industry has recently seen a growing number of platform-based approaches, focusing on the deployment of DFMA and industrialised construction. A common aid to this approach is the digital configurator, a software platform that allows for users to explore options with predefined constraints such as kits-of-parts. This paper argues that this approach has fundamental limitations, in particular that (1) configurators are developed as standalone products to context-specific problems and that (2) current implementations lack a capability for downstream and upstream flows of information between design and construction processes of a building. This research proposes an open-source Common Configurator Framework that institutes a separation between the authoring of objects for the design processes and rules applied in the verification processes; a consequent standardisation and reuse of sets of parts (objects) and sets of rules (specifications) is demonstrated. Additionally, this work formalises the decoupling of the downstream part verification process and the upstream design requirements definition, so that a Common Specification-driven design and manufacturing process becomes possible. The work is supported by a reference implementation based on the proposed Framework with a series of case studies, prototypical configurators and examples of verification/validation of pre-existing kits of parts against pre-authored specifications.
Paludiculture: peatland utilization to support climate change adaptation
Authors: Pratiwi D , Yuwati T W
Published: December 2022

Tropical peatlands are one of the largest carbon-storing ecosystems in the world. Draining tropical peatland causes environmental damage including greenhouse gas emissions. Drained peat is highly susceptible to fires that increase carbon emissions into the air. Rewetting is one way to solve the problem because, to achieve a zero or negative carbon balance, the water level should be close to or above the surface to maintain the water saturation of peat. The government of Indonesia has thoughtfully restored the peatland by implementing the 3R approach (rewetting, revegetation, and revitalizing local livelihood). After rewetting, paludiculture (wetland cultivation) is a promising land-use option for peatland. Through paludiculture, the peatland ecosystem will be improved which has already undergone drainage and will re-encourage carbon accumulative in peatland. This paper aims to determine the potential of paludiculture to support climate change adaptation including presenting challenges and opportunities in its implementation. Paludiculture has been shown to reduce greenhouse gas emissions by keeping peat moist. Besides having an ecological function, paludiculture also functions economically because it can be an alternative source of livelihood for people living around peat.

Authors: Wardhani F A , Pravitasari A E , Ridwansyah I
Published: December 2022

The regions of upstream Cisadane watershed tend to gain more flash flood cases and reduce the water catchment due to encroachment of settlement areas. Researches on flash flood disaster and land use/land cover change are important to reduce the impact of flash flood disaster to the community and environment. This study aims to: 1). Determine morphometric characteristics and land use/land cover changes and 2). Prioritize sub-watersheds for flash flood disaster management. Land Use Land Cover (LULC) and morphometry parameters were used to prioritize the sub-watersheds as a basis for flash flood disaster mitigation in the research sites. The land use data from three different periods (2011, 2015, and 2020) were modelled to understand the land use change in the research sites. Morphometric characteristics were quantitatively analysed over three aspects including linear, relief, and shape aspects over seven sub-watersheds. Morphometric parameter was considered as an important parameter in order to understand the capacity and hydrology condition at a particular watershed towards precipitation rate. According to the land use change analysis gained from 2011 to 2020, the trend of land use change was dominated by settlement area and cultivated land. These areas tend to grow in 2015 and 2020. The integration results of LULC 2020 and morphometric analysis revealed that the Sub Basin 1 (SB 1) sub-watershed was the top most priority for flash flood mitigation planning, followed by SB 7, SB 3, SB 5, SB 4, SB 2, and SB 6.
Using local wisdom for climate change mitigation
Authors: Simarmata D P , Indrawati D R
Published: December 2022

The most frequent disasters that occur due to climate change are hydro-meteorological disasters that have an impact on human life. Structural and non-structural mitigation efforts have been carried out by the government and stakeholders. However, considering that human behavior also affects the occurrence of climate change, non-structural mitigation efforts need to receive special attention. On the other hand, the Indonesian people have local wisdom related to disaster mitigation, but currently, it has not been fully utilized. Therefore, the objective of this paper is to provide information and analyze some Indonesian local wisdom that can be utilized in disaster risk mitigation. The method used is a literature review. Based on the review, there are some local wisdom related to forest conservation, spring conservation, and soil and water conservation. Local wisdom in forest conservation as conducted in Aceh is using traditional law to manage their coastal forest, and in Bali and North Maluku by constructing forests as sacred places. Spring conservation using local wisdom can be found in Samigaluh, Kendal, and Sungai Langka, commonly by giving offerings, giving thanks, cooperation, and trusting spring as a sacred place that must be protected and respected. Local wisdom to conserve soil and water is applied in Aek Latong and Lerep villages by planting long-rooted plants on slopes to prevent landslides. The synergy of government efforts and the preservation of local wisdom is a good strategy for disaster mitigation.

Published: December 2022

Strong earthquakes occur frequently with devastating effects on people and infrastructure. In cases of such catastrophic earthquakes, rescue and all other civil protection services need all available information about the earthquake itself and the consequences it has caused. In addition to the series of traditional sensors and systems used to interpret earthquakes and their consequences, remote observation sensors from space (EO) combined with geoinformation technologies (GI) are increasingly used today. By applying them, it is possible to quickly provide a wide range of useful information about the earthquake and the consequences it has caused, which traditional sensors and systems do not provide or need more time to collect and process them. Croatia was hit by two catastrophic earthquakes in 2020, on March 22nd with an epicentre in the Zagreb capital with a magnitude of 5.5 on the Richter scale and on December 29th with an epicentre next to the city of Petrinja with a magnitude of 6.2 on the Richter scale. Already after Zagreb earthquake a great need for spatial interpretation of the event and its aftermath has been recognized. Therefore, after the earthquake in Petrinja, a quick reaction of geodetic experts followed, using modern EO and GI technologies to provide information on the aftermath of the earthquake. This paper presents an overview of the sensors and systems, used data, their processing and the results obtained, i.e., the applications developed for crisis management purposes are presented.

Published: December 2022

The Baribis Fault’s status, which is located in the northern part of Java, as an active or inactive fault is a matter of considerable debate. In this study, we investigate the strain rate of the Baribis fault zone’s segment in northeastern West Java, Indonesia, as revealed by a dense network of GPS stations. We analyzed 17 surveyed GPS stations combined with continuous GPS sites over West Java from 2017 to 2021, then we estimate the GPS velocities fields. We calculated the strain rate and estimated it from the GPS velocities. In general, the Baribis fault zone experiences a significant strain rate (> 50 nano-strain/yr) with the compressional dilatation strain associated with the ongoing deformation in that area. The dilatation strain suggest that the northeastern Baribis fault in the West Java is an active thrust fault system. This information is essential to supporting a disaster mitigation program.

The Megacity Jakarta has encountered serious floods associated with high intensity but a short-duration rainfall or low intensity with a long-duration rainfall. During the rainy season, on 4 Feb 2021, Jakarta was inundated as rainfall intensity increased. However, little is known about the meteorological factors that might contribute to this heavy rainfall. In this study, we used the 6-min X-Band Doppler radar, one-hour satellite and reanalysis data to understand the spatial distribution of rainfall and explore the background conditions that might influence the enhanced rainfall over Jakarta and Bekasi River. Other than previous studies, we found that over Jakarta, the areas receiving high rainfall are more widespread and further to the northeast ocean with an intensity of above 4.5 mm h-1. High intensity of rainfall starts to develop in the afternoon over the inland areas at around 08-10Z (3.00-5.00 PM). Background condition shows a strong westerly wind speed crossing over Java Island, and this might initiate the development of rainfall over the region.

Published: December 2022

Kulon Progo is the regency in Yogyakarta with high intensity of landslide exposure. Kulon Progo also facing a new era of regional growth which potentially increases the risk. Therefore, mapping the landslide risk is required for disaster risk management. The objective of this study is to map the level of landslide risk as part of disaster risk management in the Kulon Progo Regency. The method used to map landslide risk is GeoTOPSIS (Geospatial Technique for Others Preference by Similarity to Ideal Solution). The criteria used include the hazard aspect, namely the occurrence of landslides, the vulnerability aspect consisting of population density and the percentage of built-up in the area, and the capacity aspect, which includes the criteria of settlement regional services hierarchy and the number of disaster-responsive villages. The criteria’s weight is obtained through the entropy index. The results show that the Samigaluh district has a very high-risk level of landslide, followed by Kalibawang district with a high-risk level, Kokap and Pengasih districts are at a medium level, while Girimulyo and Lendah are at a low-risk level. Other districts are at very low risk. Thus, disaster risk management can focus on districts with high to very high level of risk.
Effects evaluation of Heat Stress Index and workload to miner’s fatigue level in underground gold mining area PT Dwinad Nusa Sejahtera
Authors: Anjani R , Ariesyady H D
Published: December 2022

Mining is an activity with a high risk of accidents in open pit and underground mining sites. Various factors that cause accidents have been found through accident investigation, such as miners’ fatigue. Miner’s fatigue can be caused by environmental factors and workload that can be controlled to make a safe and comfortable working environment and prevent accidents. This research objective is to evaluate the relationship between environment factors in the form of heat stress index using humidex method and workload to miner’s fatigue level in the underground mining area PT. Dwinad Nusa Sejahtera. This research was done by measuring the working environment to know humidex, workload and miners fatigue level. Working environment conditions in the underground gold mine of PT. Dwinad Nusa Sejahtera is in a hot and humid condition with wet temperature range are 28.5–32.9°C, dry temperature range are 29.7–33.0°C, globe temperature range are 29.7–33.5°C wet bulb globe temperature range are 29.0–32.1°C, relative humidity range are 83.1–100% and humidex are 49.5–59.5°C. Multivariate analysis of miner’s fatigue level in all activity groups shows that the humidex variable gives more significant effects than the workload variable.

Published: December 2022

Rainfall is one of the factors affecting stream water discharge and flooding. The high amount and intensity of rainfall frequently cause downstream flooding. In this regard, a study with the purpose to know the trend of rainfall, discharge, and land cover of Kaligarang or Garang Watershed was conducted. Kaligarang Watershed is located in Central Java, Indonesia. Secondary data were collected from published papers and related institutions. Land cover data were derived from Landsat images. A regression analysis was conducted to observe the trend of maximum rainfall and peak discharge. The simple regression was conducted between the time and maximum rainfall or peak discharge within the corresponding year. The results showed that maximum daily rainfall 1972-1980 tended to increase. Maximum daily rainfall from 1981 to 1990 slightly decrease, however, extreme rainfall occurred in 1990. Compared to the data 1972-1980, the maximum rainfall in the period of 1991-2010 was lower. The peak discharge of the period 1961-1970 tended to decrease, conversely, starting 1971 to 2017, the peak discharge tended to increase. The reduction of the dryland forest and plantation forest were observed from every decade starting from 1990, in contrast, the settlement increased 138% from 1990 to 2020.

In flood-prone areas, coordination between parties in disaster risk reduction activities is very important. This is because disasters will directly impact the disruption of people’s lives and livelihoods, as well as hinder the process of sustainable development. This study aims to develop a public coordination scheme for flood risk reduction activities based on public resources available in North Luwu Regency. Public resources come from government agencies and the potential of the community available in North Luwu Regency with their respective tasks at the stage before, during, and after the disaster. Public coordination is expected to support the implementation of sustainable development based on disaster risk reduction in North Luwu Regency. The preparation of the public coordination scheme was preceded by a geospatial flood hazard assessment based on the characteristics of the Rongkong Downstream Watershed using a Geographic Information System (GIS). The results of the assessment form the basis for the implementation of the preparation of public coordination for DRR. North Luwu Regency is dominated by coastal land units bordering Bone Bay, plains to mountains. High rainfall, critical land use, and low-lying settlements cause the research area to be in a high to very high risk zone experiencing flooding. Sustainable development can run effectively if its implementation is based on disaster risk reduction policies with public coordination. Public coordination is carried out between government agencies and the community, who work together according to their respective roles and tasks at the pre-, during, and post-disaster stages. The results of the study indicate that more sector involvement is needed in the pre-and post-disaster stages. This indicates that public coordination before a disaster is risk prevention and reduction activity that should be prioritized in the implementation of development before hampering the sustainability of development.

A flood is a hydrometeorological disaster caused by several factors simultaneously. This paper aims to analyze the flood that hit the Sintang Regency in 2021. We analyze the flood spatially according to the method formulated by Watershed Management and Technology Center (WMTC), Surakarta. Sintang Regency grows at the Y-junction of two major rivers in the Kapuas Watershed, namely the Kapuas and Melawi River. The biophysical conditions in the upstream area affect the water level at the confluence. The results showed that 50% of the upstream Kapuas watershed is covered by forest. About 51% of land typology is vulnerable and the daily rainfall in October reached 138 mm, exacerbating the flooding in 2021. The flood emergency response status applies from October 21 to November 30, 2021. The floods inundated 12 of 14 districts in the Sintang Regency. Residents affected by flooding are caused by the location of their settlements on the riverside – the floodplain. One of the adaptations to the annual flooding carried out by the local community is to build houses on stilts. In addition, there is also lanting – a typical floating house. The location of lanting will adjust to the water level of the river.

Hydrometeorological disasters such as floods and landslides are triggered by high rainwater. The disasters often cause loss of property, loss of fertile soil layers, and loss of life. Ecodrainages such as biopore holes, silt pits, and infiltration wells are soil and water conservation technique that can be useful for reducing surface runoff and increasing infiltration so that they can be used for hydrometeorological disaster mitigation. The study was carried out in the Keduang Sub-Watershed, Wonogiri District. The purpose of the study was to calculate the volume of rainwater during the year 2017 and the volume of rainwater that could be stored. Based on the Minister of Public Works Regulation of the Republic of Indonesia No.14 / PRT / M / 2010, each person needs an average of 60 liters/day of clean water. Monthly rainwater data were obtained from the Department of Agriculture and Food Crops Wonogiri district; the population data were obtained from the Central Bureau of Statistics (BPS), and administrative and sub-watershed maps were analyzed from the Indonesia Topographic Map (RBI) scale of 1: 25,000. Total rainwater during the year 2017 was 1,027,523,049.78 m3, while the population in the year 2017 was 492,725 people. Based on the calculation, the need for clean water was 10,790,677,500 liters (10,790,677.5 m3). The average runoff coefficient in the study area was 38.57%. Therefore during 2017, there was a rainwater surplus of 631,117,906,037.99 liters (631,117,906.04 m3) in The Keduang Sub Watershed.

Upstream watershed management that is not suitable for its carrying capacity causes watershed degradation, shown by the land degradation and landslides in the upstream area (on-site), sedimentation, flooding, and drought in the downstream area (off-site). One of the disaster mitigation efforts is the implementation of soil and water conservation in the upstream watershed, which requires community participation. Generally, community participation is still passive participation. The research aimed to identify community participation in soil and water conservation, and efforts to increase community participation in mitigating hydro-meteorological disasters. The research was conducted in the Micro Naruan Catchment, upstream of the Keduang Sub Watershed, the Bengawan Solo Watershed. Data were collected through observation, in-depth interviews, and Focus Group Discussions. The data are community perceptions of soil and water conservation, local wisdom related to soil and water conservation, and community participation of soil and water conservation activities from planning to evaluation. As mitigation efforts, soil and water conservation activities include planting perennial crops and controlling surface and gully erosion. The results show that: 1) people in the upstream watershed do not fully understand the linkages between upstream and downstream in the watershed; 2) community participation in soil and water conservation is not yet optimal; and 3) the community has local wisdom in soil and water conservation. To increase community participation in soil and water conservation, it is recommended that the techniques and patterns applied are not only to reduce disaster risk but also to improve the community’s economy.
