Multi-hazard assessment and shelter allocation in DKI Jakarta: an initial study
Authors: Sihombing F H 
Published: April 2021

Abstract
Multi-hazard assessment extends the traditional disaster hazard assessment. It provides an exhaustive view of disaster hazard management where all possible disasters are observed. More importantly, the interaction and compounding impact of the concurrent disasters event should be understood thoroughly. Up until now, hazard assessments of all possible disaster events in DKI Jakarta are estimated separately. This study aimed to initiate a multi-hazard assessment of earthquake and flood for urban areas in DKI Jakarta. A scenario-based of a concurrent disaster event is created, that is the sequence of earthquake and flood occurrence, and its impact are studied using multi criteria analysis. The evacuation shelters are proposed within the affected area and the shortest path for disaster reliefs are estimated using the shortest path algorithm. The area with high level multi-hazard should carefully plan their disaster mitigation and recovery management to prepare the society for the concurrent disaster event and ensure their resiliency.

Abstract
West Aceh and Nagan Raya Regencies are traversed by the active Great Sumatran Fault, which makes the area vulnerable to geological disasters such as tsunamis. A great Indian Ocean tsunami struck Aceh in 2004. The tsunamis causing injuries, loss of life, and economic downturn as a result of the paralysis of the agricultural sector. Therefore, tsunami disaster mitigation efforts are highly needed in West Aceh and Nagan Raya Regencies. A risk assessment was carried out based on the Regulation of the Head of the National Disaster Management Agency No. 2 of 2012. This study modifies the risk index to provide a more proportional value, employing a simple yet more detailed method than the general method. HEC-RAS 5.0.7 software was used to determine the height of tsunami propagation in the scenario of an 9.1 Mw earthquake, which is based on a previous study. The assessment shows that the area is predominantly at high risk of tsunami. The area based method proved to be more detailed and appropriate than the previous risk index. Disaster mitigation plans are suggested according to both structural and non-structural approaches and are expected to reduce the risk of tsunami-related disasters in West Aceh and Nagan Raya Regencies.

Abstract
Property business is one of the most dynamic and risks businesses. The property industry has a bad reputation for managing risk. Businesses in the property sector, as with businesses in all other economic fields, need to manage each risk they face so that a balanced relationship between rentability (rate of return) and business liquidity is not disturbed by events, both economic and non-economic. Knowledge of risk management in property development in Indonesia, as seen from the available references is limited to general management theory both for industry and projects. This research is a simplification of the model 12 (twelve) stages of the development of the property industry in the opinion of Wurtzebach and Miles (1995) into 5 (five) stages namely; initiation phase, feasibility study phase, the commitment phase, the construction phase, and the operation phase by including the risk management process at each stage. The main objective of this research is to develop a risk management model of property development in the tourism area. To achieve the main objectives of this study the following secondary objectives are set: (i) exploring theories and models of risk management that are relevant to property development; (ii) identify the level of potential risk (hazard), the level of vulnerability, capacity, (iii) analyze risk factors based on the level of potential risk (hazard), vulnerability, capacity, (iv) recommend property development risk management model. This research was designed in 6 (six) stages consisting of; (i) problem identification stage, (ii) scope development stage, (iii) data collection stage, (iv) data processing stage, (v) model development stage. Conceptually, the methodology proposed in this study refers to the key steps of risk management which include identification, qualitative/quantitative risk analysis, risk response and risk mitigation. This study justifies that based on literature studies it is necessary to develop a specific risk management model for property development that is more systematic, and easy to apply. qualitative/quantitative risk analysis, risk response and risk mitigation.

Estimating deterioration rate of a bridge using changes in natural frequencies
Authors: Maizuar  , Akbar S J 
Published: April 2021

Abstract
Significant increased demand in heavy traffic loads towards heavy and long vehicles on roads could lead to an increase rate of bridge structural deterioration. This paper presents a methodological framework which can be utilized to estimate deterioration rate of a bridge using accelerometer sensor measurements. Deterioration rate is quantified using changes in natural frequencies of the bridge because it correlates with the reduction in structural capacity of a bridge. Using a case study bridge in Aceh Indonesia, the results of study show that dynamic monitoring framework using accelerometer sensor can be utilized to estimate deterioration rate of a bridge and ultimately it can be further used in the prediction of bridge residual life.

Abstract
This paper reviewed the previous research on experimental and numerical studies on the impact behaviour of fibre reinforced polymer (FRP) strips reinforced concrete (RC) slab with various (FRP) strips arrangement. This review focusses on the effect of thicknesses, arrangements of FRP strips and type of support layouts. Initially, a throughout investigation was made on the FRP and its properties. Experiments associated to impact resistance of RC slabs was also performed. Furthermore, numerous finite element model (FEM) of RC slabs externally strengthened with different arrangement FRP strips were developed with ABAQUS and ANSYS. The numerical simulations on impact resistance of RC slab models externally strengthened with different arrangement FRP strips were performed. Generally, the experimental results displayed the diagonal two-way arrangement FRP strips externally bonded on bottom surface of RC slabs and four hinge supports applied had improved the impact strength significantly. The experimental and numerical impact results obtained for RC slabs externally strengthened with FRP strips were better as compared to the control RC slabs without FRP strengthening. Afterwards, the results gained from numerical was validated with experimental results. Finally, the methods and results of experimental and numerical reviewed was reliable as a reference for the study of RC slab externally strengthened with GFRP strips subjected to low velocity impact.

Published: April 2021

Abstract
Cold-formed steel has been used widely on buildings, especially for the roof truss-structures. This material and its typical section are beneficial in weight and strength. Despite the minimum total weight, the structure can fulfil the strength requirement. For the truss installations, screws are commonly used to join the truss members due to time consideration and convenience process. However, there is a potential failure using the screw because it does not have a nut to prevent it from detaching. In this research, experimental tests of the screw connection of the cold-formed steel were conducted. The specimens consist of two groups: 8 specimens using screws were applied in the same direction and the other 8 specimens in the opposite direction. A different application of screws was aimed to observe the effect of the screw’s head, which may play a role as a nut to prevent detaching. Typical conditions of tilted screw and indented hole on the joined channel section were found during the test. The experimental results showed that the ultimate load for two different directions of screw were slightly different within the range of 0.4 – 10.0 %. The effect of the screw’s head position was minor to the resistance of the connection.

Abstract
Increase in population and urbanisation alongside demands from agricultural sector towards meeting fresh produce needs of the growing population has put severe pressure on the available natural water sources all over the world. Thus, water is undoubtedly the most contemporary crucial resources in the world. Aquatic weed plants are generally seen as a global threat to humans and aquatic ecosystem as they cannot be wholly eliminated easily. Still, various researchers and investigations have shown that they are instrumental in the field of wastewater phytoremediation, either in constructed wetlands, open ponds or hydroponic systems in an eco-friendly and economical manner with little or no sludge waste. In view of the increasing search for an alternative source of a sustainable method for wastewater reclamation, this study presents a concise review of relevant literatures on the roles of constructed wetlands and hydroponic systems in phytoremediation of wastewater. Also in the course of this study, the authors discovered that constructed wetlands and hydroponic systems have proven to be productive in remediating an array of water quality problems, with merits over the regular wetlands and conventional methods. Nonetheless, these methods are endowed with drawbacks such as inconsistency in the absorption of contaminants, large area space requirement, over dependency on environmental conditions and energy requirement. However, we suggest the use of engineered hybrid to improve its efficiency in wastewater treatment and bioenergy generation. In the case of hydroponic systems, an alternative sustainable solar energy or devices can be used to power the systems to obtain effective results at a low cost. Additionally, further studies can be employed in the use of phytoremediation technique for synchronous remediation of wastewater and production of biomass on industrial scale.

Published: April 2021

Abstract
Resilience is more capable of dealing with hydro-meteorological disasters compared to the risk. Resilience is a positive concept that puts forward adaptation efforts so that more in line with sustainable development goals. This study aims to introduce the resilience concept in dealing with hydro-meteorological disasters and apply it at the provincial level in Indonesia. The methods used are: 1) measuring the climate risk index (CRI), 2) measuring the adaptation capacity index (ACI), and 3) classifying the provinces based on CRI and ACI. Grouping CRI and ACI are used to define provinces which have the potential to bounce back better (low CRI - high ACI), bounce back (high CRI – high ACI), recover but worse than before (low CRI -low ACI), and collapse (high CRI – low ACI). The study results indicate that throughout 2017 there are 10 provinces that South Sumatra, Central Java, and West Nusa Tenggara. In contrast, 3 provinces with the most have the potential to bounce back better, 7 provinces bounce back, 7 provinces recover but worse than before, and 10 provinces collapse. In general, 3 provinces with the lowest resilience are resilient levels are Riau, Bangka Belitung, and Riau Islands.

Published: April 2021

Abstract
A massive effort to improve community resilience against disasters has been made by the Indonesian government. President Joko Widodo further emphasized this effort by ordering all governmental institutions and local governments to intensify disaster education for all the communities across Indonesia. As a contribution to this effort, Indonesia Defense University conducted a short training on basic disaster management for students, lecturers, and staffs. To evaluate the results of such training, a before-and-after study is used. The aim of this study is to examine if short training could improve participants’ knowledge in disaster management on a basic level. A pretest-posttest design was used to examine 105 participants’ knowledge before and after a five-day intervention consisting of eight basic disaster management courses regulated by the National Disaster Management Agency (BNPB). The grading system is used to understand how much the improvement of each participant, with the possibility of failing if not meeting the score threshold. This study showed that most of the participants’ knowledge on basic disaster management have improved with varying results: 60 percent of participants passed with “excellent” mark, 22 percent passed with “very good” mark, 12 percent passed with “good” mark, and the remaining eight percent failed to pass. This study provides an opportunity for humanitarian actors to use such training in order to improve knowledge in basic disaster management as a means of disaster education. However, long-term evaluation for each participant is required to examine the impact of this training on disaster resilience on community scale.

Abstract
– Lombok earthquake in 2018 gave huge impact to West Nusa Tenggara (Nusa Tenggara Barat) provincial government and its society. Lombok earthquake in 2018 is different from the others as it took place repeatedly in short time with huge magnitude. 2018 Lombok earthquake disaster emergency response has involved various elements, such as Indonesia Military Forces (TNI), Indonesia Police Department (POLRI), governmental institutions, society, as well as industries and all its resoursces. This research aims at analyzing civil-military cooperation in 2018 Lombok earthquake disaster emergency response and its affecting factors using qualitative method with primary and secondary data types. Interviews, observations, and documentations are conducted in order to collect data. This research analyzes civil-military cooperation process from the aspects of legal, organizational and governance, and operational. The result of the research shows that there was a difference in the aspect of command system used in the cooperation. The civil used agreement-based command system while military used hierarchical command system so that the military tended to be more dominant. Organization establishment as a part of effort improvement efforts has not been able to accommodate civil-military cooperation. Civil-military cooperation was initiated to fill gaps between civil and military using military resources. Thus, civil-military cooperation in 2018 Lombok earthquake disaster emergency response needed a better coordination and communication by providing a legal stand through local/governor’s regulations that accommodate all resources in West Nusa Tenggara province to cope with types of threats.

Published: April 2021

Abstract
Post-glacial evolution of the Baltic basin sedimented Quaternary soils at the great thickness (up to 30 m) in Riga, Latvia. There are present zones of different combinations of postglacial, alluvial, limnological and dune formations within the metropolitan area of Riga. The geomorphological evolution of this territory is dominated by the Baltic sea former stages, distinguishing these areas as rather complicated. The dynamic compaction was proposed below the warehouse floor of area about 40K m2 in Baltic basin silty Sand. The effect of compaction was evaluated to the depth of 10 m and extensive quality assurance using cone penetration and piezocone tests (CPT(U)), dynamic probing (DP) tests, flat dilatometer tests (DMT) and plate loading tests (PLT), was introduced. CPT(U) and DMT results were compared in terms of soil stiffness parameter evaluation prior and after dynamic compaction. The limitation of DP tests were investigated and finally also warehouse test embankment verified by PLT evaluating shallow compaction rates.
