Abstract
The purpose of this study is to develop landslide susceptibility mapping for NH67 road corridor in the Nilgiris district of Tamilnadu, India, using the Geographic information system (GIS) and multivariate statistical approach. In November 2009, North-East monsoon triggered numerous landslides in the Nilgiris district of Tamilnadu, resulting in a high death toll and considerable damage to property. The landslide-controlling parameters namely lithology, soil type, slope gradient, normalized difference vegetation index (NDVI), proximity to faults, and proximity to road, rainfall and streams were extracted from the spatial database, and the weight coefficient of each factor was computed. Then the landslide hazard was analyzed using the frequency ratio method. For verification of the model, the results of the analyses were then compared with the field verified landslide locations. It was concluded that about 3.86% and 16.23 % of the study area are in the very high and high susceptible zone. Based on this, landslide susceptibility map was then classified as very high, high, moderate, low and very low. In the course of model validation, the results were validated using the ROC curve. The AUC of Frequency ratio model was 67.5%. Therefore, the landslide susceptibility index map of the study area is considered valuable for the decision-makers of the landslide-prone region. This landslide susceptibility map can be used to carry out mitigation measures to reduce the susceptibility associated with landslide hazard.

Abstract
The deep soil with a relatively poor compressive strength has been an issue for the researchers and constructors for years since the hardships faced by them when trying to construct heavy structures on top of them. It is found that weak soils like those can be strengthened by adding different additives. Cement is commonly used for the above purpose but, since it’s expensive to use alone, cement mixed with fly ash was tested with different soils to strengthen them. The aim of the research was to find out the increase/decrease of strength when two different cement and fly ash mixtures were mixed with three different types of soils common in Malaysia in different proportions and to find the optimum percentages of each mixture to be mixed with each soil to obtain a desired strength. The Modified Standard Proctor test and the Unconfined Compressive Strength (UCS) tests were carried to study the behaviour and strength of the soils when mixed with the above additives.
Case Study: Significant factors in hazard and vulnerability assessments in flood mitigation in Padang City
Authors: Ikhvan A , Mera M 
Published: April 2021

Abstract
Flood disasters often occur in Padang City due to rainfalls with high intensity and frequency, and are exacerbated by the city located on a flatter coast up to the steep Bukit Barisan. The mountain of Bukit Barisan is parallel to the Padang shoreline, and the distance between them is relatively close, it’s just about 20 km. The present research focuses on the determination of the significant factors in the assessments of both hazard and vulnerability in flood mitigation in Padang City. The hazard assessment in the present study uses indicators of hydro-meteorological, elevation, slope, land use, and flood-frequency data. Whereas the vulnerability assessment uses indicators of Population density, Settlement density, sex ratio and age group ratio data. The results of the present study show that the most significant factors in flood-hazard assessment in Padang City are the land elevation factor from the sea level and the slope factor especially in the upper reaches of the river. Meanwhile, the factors of density levels of both the settlement and population are crucial in the assessment of flood vulnerability in Padang City.

Published: April 2021

Abstract
Lake Diatas is one of the largest lakes in West Sumatra with a variety of uses that are vulnerable to contamination that could endanger lake organisms. Therefore, the objective of the present study is to describe the vertical distributions of both temperature and dissolved oxygen (DO) in Lake Diatas as an indication of lake quality. The samples of lake water were taken at five points, namely in the middle of the lake, Teluk Kinari, Muara Danau, Gurun Datar and in Tanduk Kecil. Frequency of taking was once a month in October, November and December 2019. Variation in depth for temperature and DO observations was based on the methods of surface-water sampling (SNI 6989.57: 2008). The present study results show that the temperature range at various points with respect to lake depth variation was 20.1 to 25.9 °C with a standard deviation of 1.15 °C, while DO was in the range of 6.2 to 7.9 mg/l. These conditions still met the quality standards of lake water (Governor Regulation No. 24 Year 2010 Class II) where the temperature deviation must be less than 3 °C, and the minimum DO is 4 mg/l. By using statistical method of the two-way ANOVA, it is found that the temperature was significantly different from the time of sampling with a P-value <0.05, but the temperature did not differ significantly based on depth. The sampling time and depth of collection differed significantly for DO at 2 points close to the agricultural land. It can be concluded that the temperature and DO in Lake Diatas were still good because the oxygen content was still sufficient to ensure the survival of lake organisms. In addition, there was no indication of thermal stratification in the lake.

Abstract
Flood in Jakarta is occurred almost every year due to inadequate flood control systems to the flood prediction, inadequate drainage system, and trash that clog the drainage. The increase of rainfall is also one of the causes of flooding. That changing rainfall characteristics can affect river flow. This study aims to analyze the trend of rainfall in different time frames and its effect to flood discharge. The extreme rainfall trend is analyzed for every 15 years period from rainfall data of 1985 to 2019 for several return periods. Three period is selected for trend analysis and compared to the baseline data (1985-2019). Based on the analysis, the extreme rainfall for 1995-2009 and 2005-2019 period compared to the baseline is increased for all return periods. The increasing percentage is approximately 3-10% and 5-16% respectively. Since the extreme rainfall is increased, the design discharge is also increased for all return periods. The increasing percentage for 1995-2009 and 2005-2019 period compared to the baseline is 4-12% and 7-19% respectively. However, the design rainfall and discharge for the period 1985-1999 is lower than the baseline.

Abstract
Growing population could be one of the main factors which affect the daily increase in road movement . A developing country like Malaysia still requires transport system planning and development. In 2012, nearly 1.5 million daily and public transport trips in Klang Valley represented almost 30% of the daily main public transportation. Development of an expert system could identify problems on bus services and assist to encounter problems raised based on the expert system. Therefore, this study was aimed to develop an expert system for bus service in Klang Valley. In this study five major cities in west Klang Valley were selected, including Puchong, Petaling Jaya, Subang Jaya, Shah Alam and Klang. The Transit Capacity and Quality of Service Manual (TRCPM) was referred as studyguidelines . Three mainphases were involved in the expert system development by using MATLAB, which include analyzing job scope, management of information knowledge and development of prototype. System was named as BUS-QOS and could be used to identify the bus service quality level in specific locations and obtain suggestions from experts to improve the bus service quality of in that area. At the end of the study, validation, verification and evaluation processes should be done to check the output of system in terms of its operation and result. The result of BUS-QOS was verified based on system analysis and manual calculation. It showed that all designated attributes were almost 100% accurate. The output of the system was based on transportation engineering knowledge which could be easily used by users.
The study of split mastic asphalt pavement with latex addition for flooded road
Authors: Putri E E , Sari R R 
Published: April 2021

Abstract
This study aims to determine the effect of latex addition to the durability of the Split Mastic Asphalt (SMA) pavement mixture in order to increase its durability when the road is flooded. Durability test conducted where the sample was immersed in water for 0, 24, 48, 72, 96 hours, with latex variations of 1.5%, 2%, 2.5%, 3%, 3.5%. From the results of the study it was found that the durability of asphalt mixture without latex was higher than that of SMA with latex. The durability indexes were 6.740%, 10.648, 11.717, 13.884, 14.766 and 9.991 for 0%, 1.5%, 2%, 2.5%, 3%, 3.5% latex in the mixture respectively. The higher the index the lower the strength. In addition, the longer the soaking time the lower the strength. However, as the latex in the mixture increases, the stability was also increase achieved at 3% latex. The SMA pavement mixture with the addition of latex does not increase its durability but can increase its stability value. So, it is recommended that SMA pavement mixture with latex is only for pavement where the water level is not high.

Abstract
The hilly and mountainous topography with high annual rainfall triggered a flash flood in the upper Lematang sub-watershed. The impact caused not only damaged infrastructure, agriculture land, and even fatalities. This research aimed to conduct flash flood hazard zoning based on morphometric parameters using the GIS technique. By extracting the DEM data, it is generated to a slope map, flow direction, flow accumulation, stream order, and watershed boundary. The data were then evaluated to obtain the morphometric parameters. Parameters analyzed using the PCA approach to get the correlation between parameters related to flash flood hazards. Of the 12 parameters, the KMO value is 0.66, and a significant level is 0.001 <0.05 with a sufficient level of intercorrelation. The result of PCA analysis, two factors were obtained with an eigenvalue > 1, and the cumulative percentage of the two factors was able to explain data variations of 87.49%. Finally, using 12 parameters, the upper Lematang sub-watershed area had 48.79% very-high hazard zones of a flash flood, 16.48% high zones, 20.28% moderate zones, and 0.97% low zones, and 13.48% very-low zones. The results of this study can be used in mitigation activities as well as for integrated watershed management.

Abstract
Padang city is the administrative center of West Sumatra Province, which is located in a zone of high-level danger from the earthquake and tsunami. It has many tourist destinations. To support the growth of the tourism sector, lodgings like hotels are needed. Besides, hotels are also used for Meetings, Incentives, Conferences, and Events (MICE) by private groups and government. Currently, the disaster resilience program is being promoted both for community, agencies, and the private sector. Disaster Resilience Framework for Hotels (DFRH) is a concept of measuring disaster resilience based on six categories of predictor capital groups, namely: social, economic, human, physical, natural, and cultural. The measurements were made by distributing questionnaires to staff and managers at three large hotels in the city of Padang. The data obtained were processed using (DFRH). For the level of hotel disaster resilience measurement from the staff side, the average agreement is 82%. Then from the manager’s point of view, the measure of total agreement obtained by 86%.
Local risk managers’ and disaster volunteers’ awareness of, attitudes toward, and intention to use a local government-developed disaster information system: A Case study of SIKK Magelang

Published: April 2021

Abstract
SIKK (Sistem Informasi Kebencanaan Kabupaten or Regency Disaster Information System) Magelang is a disaster information system developed by local government in Magelang Regency to support disaster management. Despite having useful features, as with many e-government services, it shows a low adoption rate. This paper aims to explore the barriers impeding the adoption of SIKK Magelang from the perspective of local risk managers and disaster volunteers. Preliminary data were gathered by scrutinizing related disaster management documents and SIKK Magelang reports and interviewing the information system’s operators. Next, a half-day workshop was conducted with the help of BPBD (Badan Penanggulangan Bencana Daerah) of Magelang Regency to assess local risk managers’ and disaster volunteers’ awareness of, intention to use, and attitudes toward SIKK Magelang. Of the 150 people invited, 112 attended the workshop; however, 107 participants could be analyzed. We found that participants had a low awareness of SIKK Magelang and were unfamiliar with the disaster information system. After the trial session, however, they had positive attitudes toward the information system and were willing to use it in the future, especially in the context of supporting their disaster-related tasks. Our findings indicate that SIKK Magelang has the potential to be more widely used by local risk managers and disaster volunteers. More effort should be put into promoting SIKK Magelang, such as producing a clear tutorial.
Decision support system in determining the priority of disaster mitigation infrastructure development in villages level using the Simple Additive Weight (SAW) method

Published: April 2021

Abstract
Disasters are a global problem now. Particularly in Indonesia, disaster management has entered a new paradigm, from previously only focusing on emergency response activities and using mitigation and preparedness approaches. Mitigation and preparedness are carried out when a disaster does not occur. Disaster mitigation or mitigation needs to be integrated with disaster risk reduction efforts into development for the sake of sustainability and mainstreaming disaster risk reduction into village program and activity planning. In other words, a disaster risk analysis must be one of the bases in planning sustainable development. The construction of facilities and infrastructure for disaster management is also one of the priorities in village development. However, village infrastructure development planning that has been implemented has not yet considered the disaster management aspects. In this study, a decision support system model (simple additive weight, SAW) was designed, which considers aspects of disaster management that are integrated into the village development planning process.

Abstract
The issue of water sustainability and sanitation has developed in recent years, and it is predicted that by 2030 there will be increasing crises. In accordance with the six SDGs goals, it needs some efforts to ensure the sustainability of clean water and sanitation. The climate village program is one way to increase public awareness of the environment, especially providing clean water and proper sanitation and avoiding uncertain climate threats. This research was conducted with a qualitative approach using political (P), economic (E), social (S), technological (T), legal (L), and environmental (E) analysis in a village that was officially declared as a ‘climate village.’ Data collected by observation and conducting in-depth interviews with five informants who know deeply about this program. The result shows that the spirit of community cooperation is good enough to prevent environmental problems due to climate change. Every aspect of PESTLE shows a promising development, especially in Social and Environment. Still, it needs improvement for every indicator, especially financial assistance, to provide clean water and sanitation technology resistant to climate disruption.
Geographical information system for disaster relief distribution on natural disaster response
Authors: Meilani D , Hadiguna R A , Pradipta C A 
Published: April 2021

AbstractThe geographic information system that was designed was a geographic information system as a tool for the distribution process of earthquake and tsunami disasters in Padang City. This design is based on the problems that occur on the process of distributing the disaster relief such as obstruction of the distribution process of disaster relief due to abnormal road conditions, lack of information about the data of disaster relief needs at the evacuation posts so that the disaster relief provided does not match with the disaster relief needed on the evacuation post. Based on these problems, the system designed aims to provide information on optimal disaster relief distribution routes, as well as providing information about the disaster relief needs data so that the process of exchanging information about disaster relief needs data can be done more effectively. The determination of the disaster relief distribution network is using the Dijkstra Algorithm. That the shortest distribution path is obtained using the Dijkstra Algorithm with assuming that the path is traversed only to the main lane and the bridge that can be traversed is only the bridge in the Tsunami green zone. The system design is done using the waterfall method. The results obtained are that the system has four main functions. The first is to provide the optimal distribution routes, providing information about the shelter location data, providing information about disaster relief needs data, and providing information about disaster relief needs stock data. The distribution channel in the system consists of 5 safe routes to pass with the starting point is the Management Operation Center of Regional Disaster Management Authority. This research was conducted to simplify the process of distributing disaster relief because at this time officers who carry out the evacuation process are still doing data recap manually.

Abstract
The COVID-19 pandemic that has spread to almost all countries in the world, including Indonesia, has caused a multitude of socioeconomic uncertainties in various aspects of life. The present study aims to describe responses to coronavirus-related uncertainties, particularly responses from people in early adulthood. The sample consisted of 166 individuals (38 males and 128 females), aged 20-40years, from 12 provinces in Indonesia including West Sumatra, Special Capital Region of Jakarta, West Java, West Nusa Tenggara, and South Sulawesi among others. Participants completed the uncertainty response scale via Google form. The results showed that participants perceived that COVID-19 has caused uncertainties mainly in the education and economy sectors. The cognitive uncertainty of all participants was found to be at a high level. Almost all participants also reported a high desire for change, and the results vary on emotional uncertainty. In addition, job status underlies differences in emotional uncertainty and desire for change, but not for cognitive uncertainty. Conclusions are discussed with highlights on methodological limitations and the need for further research related to psychological outcomes of uncertainty.

Published: April 2021

Abstract
This research aims to assess the adaptive capacity of three adaptive strategies applied in Cirebon and Pangandaran by estimating community assets under threat of Sea-Level Rise (SLR) through open-loop system. Firstly, SLR in Cirebon and Pangandaran each month from 2006 to 2100 is simulated using ocean heat flux and ice melting model data by Representative Concentration Pathways (RCP) 8.5, Intergovernmental Panel of Climate Change Assessment Report (IPCC AR) 5. This simulation result is then added with ocean phenomena such as tide, Indian Ocean Dipole (IOD), Madden-Julian Oscillation (MJO), storm surge, and Kelvin wave along with their frequencies. By the year 2100, the sea level in Cirebon will reach 115.65 cm and 148.09 cm in Pangandaran. Secondly, the SLR and applied strategies are converted to be inundation maps of community assets. Overall, the result shows the best policy for both regencies is protect which has an adaptive capacity value of 96.30% and 76.65% respectively. But deeper, the adaptive strategy for each district in both regencies differs one to another.
