Abstract
Sawahlunto is a city located in West Sumatra, Indonesia, known as a city rich in coal mining activities and often referred to as the “City of Batubara.” The history of Sawahlunto coal mining dates back to the Dutch colonial era in the late 19th century when coal was discovered in the area. It has been designated as a national geopark area (KGN) in 2018 and then designated as a UNESCO World Heritage Site (WDU) in 2019. One of its prominent landmarks is the Ombilin Coal Mine, which. Sawahlunto also boasts other historical landmarks and preserved buildings. The study objectives are: to identify rock types, topographic features, and other phenomena, along with measurements of heritage buildings; to analyze the rock distribution for determining the origin of rocks for heritage buildings in urban development and to describe the heritage building; and to describe the development of heritage building in Sawahlunto The mixed method was incorporated, where geological mapping method was used to determine information on the distribution of rocks and material origin for urban development, heritage building foundation analysis and content analysis on heritage buildings. The study found the building materials are rocks from the result of erosion originating around the city of Sawahlunto are: Sedimentary rock facies in the Ombilin Basin. The heritage buildings used local materials as they were abundant during that time. Sawahlunto’s heritage buildings not only have historical and cultural heritage, but also contain urban geological heritage that should be further studied as part of urban development.

AbstractMany researchers claim that human influence on local climate change is unavoidable. Global climate change can cause catastrophic damage (disturbing human health, ecosystems, and socio-economic aspects). Characteristics of areas that affect rainfall, such as topography, slope, and land use and cover (LULC). This study aimed to specify the relationship between LULC changes and the local climate context in Aceh Besar District. LULC changes are analyzed with a transformation matrix. The method used to determine the occurrence of climate change is the Mann-Kendall Test, which looks at whether there is a trend in a data series based on the relative rankings of the data spanning 1992-2020. The Mann-Kendall test analysis results show that climate variables that change significantly on rainy days are weather temperature, humidity, and wind speeds. The statistical test results show that there has been a change in the local climate, as indicated by the variables of The Sen’s Slope Estimator test results in an increase in temperature of 0.002°C every year, and humidity increases by 0.01%. When viewed from LULC, one of the influences is changing (2000-2020) from forest, cropland, and bareland to built-up areas.

Published: December 2023

Abstract
Livestock, especially ruminants, potentially emit nitrous oxide (N2O) and methane (CH4) gas through enteric fermentation activities from the eructation process and dung management (DM) activities. This study aims to determine the emissions gas of CH4 and N2O from livestock ruminants in the livestock breeding-green in Jember. The gas emission calculation method follows an international agreement initiated by the Intergovernmental Panel on Climate Change (IPCC) 2006, with Layer-2 for CH4 and Layer-1 for N2O. The results showed that the amount of CH4 emission from enteric fermentation was 103,321 tons CO2-eq per year, higher than DM, which is 4,510 tons CO2-eq /year. The amount of indirect N2O emissions from DM is 0.0763 tons CO2-eq /year, higher than direct N2O emissions from DM, which is 0.0527 tons CO2-eq /year.

Abstract
State Senior High School (SMAN) 96 is the first high school in Jakarta to be officially designated as a net-zero school with a Greenship Certificate by the Green Building Council Indonesia. In contrast, State Vocational High School (SMKN) 73 is not a net-zero school. The two schools are 100 m apart, located in Cengkareng District, West Jakarta. The purpose of this study is to analyze the application of CO2 emission reduction technology in the two schools. This study used a quantitative method. Because the school setting is in the urban area, it is not easy to find so-called indigenous technology. This study will look at the best available low carbon technologies implemented in both schools. The results show that SMAN 96 has electricity consumption and CO2 emissions lower than SMKN 73 because SMAN 96 already using the energy-efficient devices/appliances and minimizing the usage of AC and refrigerator which can increase the CO2 emissions. To reducing CO2 emissions, the two schools already implementing the use of solar panels. Furthermore, by using the solar panels it can save the electricity consumption and also solar panels produces emissions smaller than total electricity usage.

Abstract
This research conducts Classification of Public Perceptions of Transportation Access Development in Darmo Corridor Surabaya using SVM and Naive Bayes methods. The increasing mobility demands necessitate adequate public transportation facilities, such as the Surabaya bus, which has been operational since 2018. The Darmo corridor has witnessed significant development in public transportation facilities and infrastructure, serving as a transit point between two Surabaya bus routes. The purpose of this study is to evaluate public perception towards the implementation of Transit Oriented Development (TOD) concept in the corridor. In this study, a qualitative descriptive analysis was conducted on various aspects of TOD implementation, such as pedestrian paths, bicycle lanes, and green open spaces. Furthermore, public perception was analyzed using Naive Bayes Classifier and SVM methods by collecting data from Twitter accounts and giving weights based on the frequency of words in the tweets. From the analysis it could be concluded Naïve Bayes is not suitable for classification because it’s not stable enough, the SVM Methods matchs 95% proven when its repeated for 5 more time it. The results showed that the Darmo corridor successfully implemented the TOD concept well, with 90% of the community giving a positive response to the TOD implementation in the area. This finding indicates the success of TOD initiatives in improving transportation facilities and infrastructure in Darmo corridor.

Abstract
Water security is one of the crucial concepts in the supply chain of drinking water supply. This concept has become essential, especially since water security has been mainstreamed into drinking water supply activities in Indonesia through a Drinking Water Security Plan (RPAM). This study aims to apply the Asian Water Development Outlook 2020 (AWDO 2020) method as a quick assessment method related to the safety level of drinking water. The research was conducted at community-based water supply and sanitation (PAMSIMAS) locations in Pakem and Cangkringan Districts. The two sub-districts are in the disaster-prone area (KRB) III area of Merapi. In Pakem sub-district, locations studied were PAMSIMAS in Watuadeg and Pandanpuro villages. In Cangkringan sub-district, research was conducted in Dliring and Kalitengah Lor villages. Modifications were made by adding indicators to the Rural Household Water Security AWDO 2020. The initial indicators included water availability, sanitation access, health impact, and affordability. The added aspect is the impact of water resistance with the threat of a volcanic disaster. The scoring of the questionnaire results from a scale of 1-4 is analyzed from each aspect to get the total score determining the water resistance index. The total score obtained for the four locations is 16.03-17.42, which means they all are in the effective stage. There are also some deficiencies in applying the AWDO 2000 method, such as the scoring details and the possibility of scoring interpretation errors.

Published: December 2023

AbstractAs industrial activities grow and increase, it is directly proportional to the wastewater produced, which is disposed of into the river. One of the calculation models commonly used for evaluating surface water quality is the water quality index (WQI). The method produces uncertainty in the conversion and is site specific dependent. The data collected for the last five years used a comparative method to assess the status classification of those rivers’ quality. In addition, this study also aims to classify the river quality status and evaluate the WQI model in determining the impact of industrial activities on Sumatra Island and Kalimantan Island, the five longest rivers in Indonesia. This paper uses the WQI to review the water quality condition of Indonesia’s five longest rivers, i.e., Kapuas River, Mahakam River, Barito River, Batanghari River, and Musi River, where the community heavily uses these rivers for their daily needs. This review study concluded that the WQI of a river could vary depending on the measurement data used in calculating the WQI value. The data describing the WQI of a river is a momentary WQI or periodic WQI. The study is expected to be used as a basis for developing a sustainable water pollution control strategy to maintain the grade status of a river according to its classification.

Abstract
Marine pollution, mainly plastic waste, has become a worldwide problem, especially in Indonesia. Indonesia is the second contributing country after China, with 10% contribution of the source of plastic pollution in the world. In the ocean, plastic will fragment into smaller pieces (less than 5 mm), known as microplastics (MPs). MPs can harm wildlife, especially fish, due to their toxic characteristics or other toxic substances attached to them. Indonesia, especially coastal areas, is known for its high consumption of marine fish, so this study aims to investigate the microplastics in fish sold at lokal fish markets in Bantul Regency, Yogyakarta Province, Indonesia. The fish sold came from the southern sea of Java (Indian ocean) around Depok Beach, Cemorosewu Beach, and Parangkusumo Beach. Three types of fish dominate namely Skipjack, Snapper, and Pomfret. The National Oceanic Atmospheric Administration (NOAA) and Wet Peroxide Oxidation (WPO) methods were used to examine fish samples. Identification of MPs was made based on shape and colour. The results showed that the most common MPs found were fibres with a total number of 36-91 particles/fish. The dominant colour of MPs is transparent, with a total of 552 particles from total samples. Although the analysis was only conducted in fish intestinal, there is potential that MPs will be found in fish meat. The chemical characteristics of MPs were determined using the Fourier Transport InfraRed (FTIR). The types of plastics found were Polyethylene (PE), Polypropylene (PP), and Nylon.

Published: December 2023

Abstract
Small-scale mining, or conventional mining, is quite common in Indonesia. Almost all of these artisanal mining activities disregard environmental safety around the mining areas. The current widely used gold extraction method for gold exploitation is the amalgamation method, which utilizes mercury (Hg). The use of this method can result in environmental pollution from mercury. Based on the impact of mercury that can contaminate the environment, it is necessary to treat gold mining wastewater before disposing of it into the environment. One alternative that can be used to treat gold mining wastewater is to use plants (phytotreatment). The aims of study was to observe the tolerance of Hg to Typha latifolia and Pistia stratiotes plants, The methods was call the Range Finding Test (RFT). The study was conducted using synthetic Hg at concentrations of 0.3, 0.7, 1, 3, and 6 mg/L and a control (0 mg/L) in a batch reactor. The reactors were added with soil up to 25% as a growing medium. The physical observations of plants were carried out for 28 days. Typha latifolia and Pistia stratiotes could both grow and thrive at a Hg content of 6 mg/L, according to physical observations of the plants. In the first seven days, Pistia stratiotes plants exhibited a stress reaction in the form of yellowing and falling leaves. Both plants had vigorous, extended root development in all concentrations. Based on these findings, phytotreatment can be utilized as an alternate therapy to lower the Hg levels in gold mine wastewater.

Abstract
This study identified and analysed the composition of solid waste generated by retail malls in Central Jakarta City, with a particular emphasis on determining the potential applications of Refuse Derived Fuel (RDF) and Black Soldier Fly (BSF) technologies. The research involved exhaustive waste samplings, taken at various activities within multiple X shopping mall in order to determine the categories and amounts of waste generated. The collected samples were subjected to a thorough analysis to determine the proportion of organic and inorganic refuse and assess their suitability for processing using the RDF and BSF techniques. The investigation revealed that X Shopping Centre’s solid refuse consists primarily of inorganic waste (77.42%) and organic waste (22.58%). Essential waste characteristic analyses were conducted to determine the combustion energy potential of the inorganic waste, yielding a moisture content of 41%, an ash content of 6%, a volatile matter content of 94%, and a calorific value of 10,502 kcal/kg. Using information on waste composition and characteristics, the study investigated the potential use of RDF and BSF technologies to manage and repurpose the generated waste. The RDF processing potential was calculated to be 8.77 tons per day, while the BSF processing potential was 3.11 tons per day. This estimate illustrates the substantial capacity of these technologies to manage and convert large quantities of refuse into valuable resources. In addition, the study assessed the monetary implications of implementing RDF and BSF technologies in the context of X Shopping Mall. The estimated investment required to implement these technologies is 11,198,926,800 IDR.

Published: December 2023

Abstract
Malaysia’s Shared Prosperity Vision 2030 Strategic Thrust 1 stated that the business and industry ecosystem to be strengthened and expected to contribute almost 50% of the country’s GDP. This agenda is indeed in line with Goal 11 of UN-SDG that aims to develop sustainable and resilient cities and communities by 2030. However, due to the result of the global pandemic in 2020, many micro, small and medium enterprises (MSMEs), particularly tourism-services oriented, were heavily affected and, unfortunately, the last to recover. The industry suffered a significant decline in revenue due to halting of operations, travel bans, and lockdowns resulting in delays to the continuity plan of business operations. As a result, there was a reduction in workforce and some of MSMEs were forced to cease their operations. Based on questionnaire-guided interviews of 53 respondents, this paper firstly will deliberate extensive review of the impacts of COVID-19 pandemic on MSMEs in East Malaysia state of Sabah, particularly in tourism-centric regions of Kundasang and Kota Belud areas. Secondly, the explanation of smart GIS solutions through network analyses, in helping MSMEs rejuvenate their business operations as soon as possible during and after the disaster events. The results from GIS Network Analysis for disaster event simulation and outputs show that each case study region reflected differently according to different disaster types and intensities. From the outputs, the study proposed an integrated framework consisting of MSMEs’ capital of economic, social, and environmental problem-solving phase, together with an operational framework of Disaster-Business Continuity Plan (DBCP).

Published: December 2023

Abstract
The national activity centres (Pusat Kegiatan Nasional – PKN) areas, especially in Sumatera Island, are closely related to the land cover change phenomenon. This study aimed to identify the land cover change projection and assess its suitability with the spatial pattern plan in the “Rencana Tata Ruang Wilayah” (RTRW) which focuses on the study area including Medan, Pekanbaru, and Padang. The integration of remote sensing data, geographic information systems (GIS), and spatial analysis techniques are used to identify and assess the patterns of land cover change over the specific period. The analysis of land cover change patterns is performed using Landsat-7 and Sentinel-2A imagery data which processed in Google Earth Engine (GEE). Furthermore, Cellular Automata and Artificial Neural Network (CA-ANN) modelling is used to identify land cover prediction using transition rules like main road as driving factor then followed by overlay analysis to assess its suitability with the spatial pattern plan. The result shows the different level of each land cover classification in sub-district level. The proportion of the land cover projection suitability in Medan at 2042 was 84,92%; in Pekanbaru at 2040 was only 58,51%; while in Padang at 2030 was 77%. This findings can be able to serve as a suggestion for stakeholders in formulating effective strategies for spatial planning evaluation and managing land cover uses, especially in several national activity centers in Sumatera.
Mapping Vulnerability to Flood in Urbanizing Watershed: The Case of Surakarta Urban Region
Authors: Rahayu Paramita 
Published: December 2023

Abstract
The vulnerability of urban areas to flooding increased along with the rapid urbanization process. The study selected the Subosukawonosraten (Surakarta, Boyolali, Sukoharjo, Karanganyar, Wonogiri, Sragen, and Klaten) Region as a case study to assess the vulnerability. The ESA framework: exposure, sensitivity, and adaptability—is applied. Exposure is examined using the built-up index in 2020. Sensitivity is assessed based on population density in 2020. Additionally, precipitation and topography are also discussed. The study uses hot spot analysis to pinpoint the most populated and developed areas of the region, which are Surakarta and its peri-urban. Following that, the study investigates to what extent urban villages situated in this hot spot can adapt in light of the floods that often occur in the region. The findings imply that, primarily because of rapid urbanization, the strategy to deal with vulnerability should be considered an important regional-scale strategy that should integrate technical and community-based development approaches to establish a more sustainable strategy for resiliency.

Abstract
A natural disaster is a phenomenon that causes loss and has an effect on society, specifically on vulnerable society. This research mentions vulnerable communities as women and children. In order to reduce disaster impact on vulnerable communities, it is essential to examine the preparedness level of the community. Slawi is one of the urban areas in Tegal Regency with a dense population and the potential for natural disasters. The objective is to embody a resilient community by increasing vulnerable communities’ preparedness in disaster mitigation. The method used is qualitative, and the main data collection technique is through Focus Group Discussion using participatory mapping analysis with the help of GIS. The result shows that vulnerable communities already know and understand their task and roles in disaster mitigation. Some crucial factors affect vulnerable communities’ preparedness levels in disaster mitigation. There are risk-understanding levels, knowledge of disaster mitigation precisely, and collaboration among local organizations. The urgency of government role and institution-related to provide guidance, training, and resources are needed to strengthen the vulnerable community preparedness. This research expects to provide stakeholders, regulation makers, practitioners, and academics with the knowledge to actualize a resilient community. With the increased preparedness level of vulnerable communities, the disaster impact on communities can be reduced, and they can be more resilient in dealing with natural disasters.
