Abstract
Air Tawar Barat Village, North Padang District, including the one of most vulnerable areas to the threat of earthquake and tsunami in Padang, West Sumatra Province, Indonesia. Earthquake disasters can result tsunami risk and unpredictable when it will occur. One of the efforts to reduce the risk of tsunami disasters is to increase the capacity and attitude of community preparedness against disasters. This study aims to identify the capacity of residents to face the tsunami disaster in Air Tawar Barat Village, Padang City, West Sumatra. The method is a quantitative-qualitative research through questionnaires assessing the capacity of communities and deep interviews related disaster knowledge to the subdistrict office, Kelompok Siaga Bencana (KSB) and local residents. Secondary datas obtained from the documentation in Subdistrict office and KSB, as well as literature review. The results of the study, could be concluded that the residents had good knowledge of disaster mitigation with the percentage of 64%, preparedness plans and actions had a good value with the percentage of 68.88%, perceptions and traditions of residents in preparedness attitudes (local culture and wisdom) well enough with the percentage of 50.67%, leadership and programs of the government and KSB was poor enough with the percentage of 45.33% and the role of information in the attitude of preparedness is very important with the percentage of 70%, then the average capacity level was still at low-level with the percentage of 56.87%. Based on this, the communties, KSB, local agency and the government need to have well integrated communication and coordination . It could be seen that residents likely lack of understanding about the duties and function of the KSB in taking efforts to minimize disaster risk besides this far the programs in Air Tawar Barat sub-district did not run smoothly and postponed due to limitations.

Abstract
The current SNI 1726:2012 code was developed to be the new Indonesian Seismic Design Code, SNI 1726:2019 based on the 2017 Indonesian Seismic Hazard Maps and the ASCE 7-16. It has a direct impact on the development of seismic resistance code for building design in Indonesia. The new 2019 risk targeted ground motion of spectral acceleration (SS and S1), and risk coefficients, for both short (T = 0.2s) and 1-second (T = 1s) periods, respectively have been published. The paper discusses the difference of the design response spectra for building design of seven districts of Riau Province, Indonesia, according to those standard codes. The analysis was performed for three different site soil classes, that is hard (SC), medium (SD), and soft soil (SE). The design response spectra comparison of SNI 1726:2019 and SNI 1726:2012 of even districts in Riau Province, namely Bangkinang, Bengkalis, Pekanbaru, Tembilahan, Pasir Pangaraian, Dumai, Teluk Kuantan, and Siak were considered to represent the entire territory of Riau, from North to South that chosen as samplings. The purpose of this study is to evaluate the direct impact of the new code SNI 1726:2019 on design response spectra (DRS). Based on the analysis conducted at 8 cities/ districts, the improvement of DRS 2019 compared to DRS 2012 for site classes SC, SD and SE are less than 0.1g except for all site class at Tembilahan and Teluk Kuantan.
Trapezoidal corrugated plate behavior on Steel Plate Shear Wall
Authors: Nidiasari  , Haris S 
Published: April 2021

Abstract
Corrugated Steel Plate Shear Wall (CoSPSW) is a corrugated steel plate used in steel frame structures with shear walls instead of flat plates. Corrugated steel plates are reported to have greater strength than using flat steel plates. This study’s specimen model is a one-story steel frame with shear walls using trapezium corrugated plates at an angle of 45°. The analysis was carried out with a finite element analysis using Patran and MSC Nastran software. Structural loading in the form of a monotonic static load with displacement control. The thickness of the corrugated steel plate is varied to analyze the effect of the depth of the corrugated plate on the behavior of the structure. The analysis results of the specimen model indicate that the value of strength, stiffness, and ductility will increase along with the thickness of the corrugated plate. The CoSPSW structure begins to behave in ductile when the corrugated plate’s depth is > 2/3 of the cross-section web thickness.

Published: April 2021

Abstract
The soil in different regions has many fundamental problems, including a high groundwater table, deformation of highly compressive clays, peat, etc. Most areas of these zones are waterlogged, swampy, and characterised by weak soils, making it difficult to construct them without addressing the stability of such structures. In many cases, soil conditions and soil materials are not ideal for the proposed or planned development. In such cases, the geotechnical engineer will consider how to resolve possible issues with feasible solutions carefully. This paper presents work resulting in the development of software that is used as a tool to guide and select the type of improvement and soil assessment. It allows users to learn about soil improvement and ground modification in engineering practice while providing the user with a tool that helps to solve soil improvement problems. An expert opinion was designed and conducted to obtain the weighted matrix for evaluation selection of improvement type based on specific criteria. A Software Development Life Cycle (SDLC) was followed, and in terms of design, implementation, testing and evaluation were conducted. The evaluation result based on the System Usability Scale was performed and evaluated, and it shows the proposed tool was accepted and suitable to use by the end-user.
Slope stability analysis for landslide mitigation in Satui, Tanah Bumbu, South Kalimantan
Authors: Salimah A 
Published: April 2021

Abstract
Satui is a Tanah Bumbu sub-district that is in the territory of South Kalimantan yielding mainly coal. The illegal and uncontrolled coal mining formed a steep slope in this area. The slope was exactly shaped close to a telecommunication tower building and other buildings. The excavation in this area provoked an eroded and imbalanced slope thus triggering a landslide. This research is aimed to deal with erosion prevention and disaster risk reduction to mitigate the environmental impact. The investigations of slope and soil conditions are used to obtain soil data as the first stage of research. The second stage is analyzing the slope stability toward soil data. A stable slope condition is indicated by existing analysis with FoS 1.66. Yet to avoid future disaster risk, slope reinforcement by employing Geo-Anchor is performed. The last stage is executed by implementing the proposed drainage and slope surface formation.

Published: April 2021

Abstract
Pagar Alam city is one of districts in South Sumatera province that has an area of ± 63,366 hectares (Monograph of the city of Pagaralam, 2013). So far, the people of Pagar Alam city, especially the north Pagar Alam district, have no reference to determine the soil type of its area; therefore this study carried out an analysis of the soil characteristics and conducted a mapping of its types of characteristics and the soil water content in the north Pagar Alam district.A geomap is a map that depicts existing image of the earth’s surface which is represented on a flat surface in a certain projection. Geomapping is a process of measuring, calculating and depicting the earth’s surface using certain methods. Soil is the surface layer of the earth that comes from parent material that has undergone an advanced process, due to natural changes under the influence of water, air, and various kinds of organisms, both living and dead (Dokuchaev 1870).After conducting 20 soil sample tests, it can be seen from the interpolated and overlayed sub-district map that the land in North Pagar Alam district has sandy silt soil where 19.69 km2 of the area has good grades of the soil and the other23.90 km2 of the area consists of poorly graded sand.
Shaking table tests to investigate the influence of grain shape on tnb he excess pore water pressure
Authors: Muhajirah  
Published: April 2021

Abstract
Liquefaction that occurred in the Palu city in 2018 is the most devastating natural phenomena. The liquefaction phenomenon is a condition in which a saturated soil loses its strength due to an earthquake. This study aims to determine the increase in excess pore water pressure in solid particles and void particles after they are subjected to earthquake loading. Testing is done by shaking the table. Earthquake loads are modeled with cyclic loads, which are sine waves with acceleration amplitudes of 0.35g and 0.38g. The results showed that liquefaction conditions had not yet occurred in cyclic load applications with an acceleration amplitude of 0.35g and a time duration of 7s. At an acceleration amplitude of 0.38g with a time duration of 60 s, the sand model underwent liquefaction at 7s after the test began. Analysis of the results of transducer records installed at a distance of 0.10 m from the surface of the test model shows that the addition of pumice by 10%, 30%, and 50% can reduce pore pressures by 15%, 62%, and 85%, respectively.
Analysis of water availability and planting index in dams in Bedadung watershed
Authors: Jatmiko B C , Andriyani I 
Published: April 2021

Abstract
The increasing population causes the government to work to improve food security. One of the policies adopted is to increase the productivity of agricultural land. Increased productivity of agricultural land can be increased by increasing the crop index. Planting index is the total area for crops per planting season for a year. In this case support from irrigation, the sector is very important. From the preliminary survey in the study area, we found some damage to the irrigation assets that might reduce the performance of the assets which caused the crop index to be lower than the maximum crop index (300%). This study aims to (1) calculate the availability of irrigation water, (2) calculate the crop index, and (3) analyze the potential increase in the crop index and the expansion of agricultural land. The results showed that there were 80 dams (44.4%) experienced abundant water but had a crop index value of less than 300%. Thus, the service area of 80 dams can be increased the value of the planting index to 300%. While there are 100 dams (55.6%) experiencing water shortages. In this case, the recommendations that can be given are providing water supply through the construction of a reservoir or changing the pattern of planting paddy - paddy - paddy into paddy - palawija -palawija. We conclude that water delivery in the Bedadung Watershed area is not effective. This can be caused by damage to irrigation assets. Therefore, a recommendation that can be given for further research is the effect of irrigation asset performance on irrigation services.
A multi-objective optimization model for reservoir operation during droughts
Authors: Hidayat S , Saidah H , Budianto M B , Harianto B , Putra I B G 
Published: April 2021

Abstract
General guidance for reservoir operation can be referred to as the Standard Operation Procedure (SOP). Real circumstances such as drought, however, do not necessarily comply with these ideal assumptions, which then trigger the studies on optimal hedging rules. More frequent mild droughts are preferred to less frequent severe droughts. In the present work, the-constrained-based multi-objective optimization model was developed to optimize hedging rules for a reservoir located in Lombok Island, Central Indonesia. The rules were aimed to minimize two objective functions namely maximum Single Shortage (SS) and Total Deficit (TD). The former is a measure of reservoir operation during drought in short-term, whereas the latter is for long-term evaluation. Results show that these two measures are conflicting in nature, that is, the greater the SS, the smaller the TD and vice versa. The tradeoffs between SS and TD can be a helpful assist for water operators in executing their routine daily tasks by providing water allocation alternatives.

Published: April 2021

Abstract
This study was conducted to evaluating the performance of existing coastal protection structure to restrain the rate of erosion as a result of the influence of hydrodynamics process. Condition that reviewed was in form of distance shoreline as simulation results to initial reference line before. STWAVE module used to determine wave height at near shore as transformation of deep water wave height that determined before from SMB method. One Line Model was conducted to get shoreline change in each time step calculation. Model consists of two conditions, with the absence of coastal structures and with structure respectively. The simulation result show that potential erosion occurs at Batang Arau river mouth with no protection structure. Large erosion predicted around 59.04 meters from the shoreline position early. With coastal protection, model result obtained sedimentation of 7.33 meters coastline from its initial position. This occurs at a distance of 475 meters from the boundary domain. Modeling results also showed erosion is 18.39 meters at a distance of 250 m from the boundary domain. This is likely due to the limited modelling conditions that without reviewing of littoral transport direction that occurred in perpendicular to the coast. Result study show that the presence of a groins in Padang coasts looks already quite effective to maintain the shoreline of the littoral transport direction, however the installation of groins seemingly did not give significant meaning in the addition of the coastline.

Abstract
LRT System is an accessible urban public transportation in Malaysia, especially in Klang Valley. People can commute easily from one place to another. The operations of the LRT System are entirely dependent on the electric power supply, from the movement of trains between stations to the facilities inside the train itself. High consumption of electric grid has contributed to the increase in environmental pollution. In the long-term, the effect can be seen in the decrease in sea level as well as drop-in water supply. Due to that, renewable energy demand is continuously increasing, and current prediction shows that this trend is going to further continues yearly. Usage of electricity from renewable sources such as the solar panel has been proposed in this project paper in order to reduce the negative effect been encountered. The solar PV is a mechanism that can transform the sunlight into direct current electricity by using semiconductors. Hence, with the use of the solar panel, it will reduce energy pollution and climate change impact due to high consumption of electric grid. This research is meant to explore the possibility of using solar panels as an alternative for generating electricity for the Light Rail Transit (LRT) as renewable energy instead of using the power grid. The goal for this project report is to understand the requirements in implementing solar energy on the LRT System in Malaysia.

Abstract
The Kuranji watershed is one of the watersheds in the city of Padang, which is currently experiencing development due to rapid population growth. This has resulted in land conversion from areas that have vegetation to built areas such as settlements. This affects the balance of the Kuranji watershed ecosystem and can lead to geological disasters. Therefore an initial analysis is needed in the development of the Kuranji watershed in the future. This study aims to analyse the interrelation of rainfall and morphometric characteristics that have an impact on geological disasters. The data used are data of maximum rainfall and maximum river discharge in the Kuranji watershed from 2009 - 2018. DEM data (30x30) used to calculate morphometric aspects, consisting of linear aspects, area aspects and relief aspects. The calculation of these aspects is done by a Geographic Information System (GIS) approach using ArcGIS 10.6 software. The result shows that the Kuranji watershed has an area of 22469,55 ha with dendritic drainage patterns. The linear aspect reveals that it has 1894 rivers with a total length of 774,6 km. This aspect explains that with the many tributaries, the Kuranji watershed has the potential to cause flooding. Aspects of the area explain that the Kuranji watershed has an elongated shape, steep slope and causes a rapid and large run-off discharge. Drainage density is at medium level with a value of 3,45 (km/km2) which is close to the high category. The higher the drainage density the smaller the chance of water for infiltration and the greater the river discharge. The relief aspect explains that the Kuranji watershed has a height between 0-1860 meters above sea level. Relief ratio and gradient ratio have a value of 0,08. Gradient ratios with high values result in fast and swift flow of surface and river water flow. This has the potential for landslides, channel erosion and river wall erosion. High rainfall, extreme morphometric characteristics, causes the Kuranji watershed to have a great potential for geological disasters.
