Authors: Duan Xiaoxue
Published: April 2021

In order to enhance the security of wireless networks and enhance the ability of data acquisition, processing and transmission, the security defects of wireless networks are diagnosed based on the modal symmetry algorithm. According to the amplitude of the defective signals collected by wireless network sensors, the average value of the signals collected by the centrosymmetric sensors is linearly subtracted, and the asymmetric modal information and the asymmetric modal amplitude of the axial position of wireless networks are obtained. On the basis of the original defect vibration signal graded by variational mode, several eigenmode components are obtained, and then the ranking entropy of each modal component is calculated. The ranking entropy is input as eigenvector to support vector machine classifier to complete the classification and recognition of wireless network security defects. The experimental results show that this method can accurately diagnose the security defects of wireless networks in different locations. The more complex the wireless network is, the higher the accuracy of the diagnosis results is and the shorter the time consuming results are. After the defect diagnosis, the wireless network data acquisition, data processing and transmission capabilities have been enhanced.

Published: April 2021

For the connection of DGs in distribution network, the fault power flow is different from that in normal operation. Further, the size of the fault current is limited by the electronic components and greatly reduces. Therefore, fault detection, the protections and their coordination become very complex. Fault detection technology helps to achieve fault isolation and recovery, and plays an important role in distribution network control and operation. This paper proposes a data-driven fault feature selection method for distribution network. This method collects various electrical quantities during normal and short-circuit faults of the distribution network as a feature library, and uses the support vector machine-recursive feature elimination method for feature selection to remove redundant features. The optimized fault features can be used to fault detection for distribution network with DGs.

Authors: Zhao Junfeng , Huang Xinyi
Published: April 2021

PSO is easy to fall into local optimum, and has the defects of low convergence accuracy and difficult convergence. In order to solve this defect and improve the accuracy of the algorithm, the modified PSO algorithm by Geng is applied to solve virtual enterprise partner selection with normalization, by changing dynamically inertia weight for the number of iterations. Furthermore, for the particles with small fitness, a large inertia weight is set to accelerate the approach of particles like the optimal solution region. Finally, results of numerical example show that the search speed of improved PSO is faster than that of standard PSO, which indicates that adding dynamic inertia weight can greatly shorten the search time of the algorithm and accelerate the convergence.

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

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

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

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

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.

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.

Until May 5, 2020, there were 131 positive confirmed cases. Six of them are primary health care officers. The purpose of this study was to measure the description of the use of Personal Protective Equipment (PPE) in the prevention of Covid-19 in primary health care staff in Padang City. This research uses descriptive quantitative method which was carried out in March - June 2020 in Padang City primary health cares. The study population are primary health care officers who deal with patients directly in the city of Padang with a sample of 100 people. Data were collected using a questionnaire and analyzed univariately. The results showed that 55% of staff used incomplete PPE, 57% are old, 54% have low knowledge, 54% have negative attitudes, 46% PPE are not available at the primary health care, and 45% lacked leadership support. The results also noted that 58% of officers began using PPE when announcing the first positive case in Padang City. For further research can conduct bivariate analysis and qualitative research for in-depth analysis.

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.

The covid-19 pandemic had struck the world and affected the national development, especially in Indonesia. Many construction sectors experience disruption; therefore, it directly impacts the contractor’s performance. This study analyzes the internal and external dominant factors that affect the contractor’s performance during the covid-19 pandemic in West Sumatra Province, Indonesia. This study was a cross-sectional study with a qualitative approach using a self-administered questionnaire with 26 variables. Fifty eights respondents in the water resources field projects have participated in this study. The data was collected and analyzed by using multivariate analysis (logistic regression test). It was concluded that the distribution of salaries on the managerial aspect becomes dominant in the internal factor. Government policy factors regarding the implementation of work outside become the crucial external factor that significantly affects the contractor’s performance. So, it is suggested to the well-organized distribution of salaries and well preparation of conditional administration related to government policies during the Covid-19 pandemic.

Published: April 2021

This paper presents an alternative design of a temporary house made of bamboo and its manufacturing process to become a prototype that can be seen by the public. It was expected that by seeing this prototype, the people who lives around disaster affected areas can build their own temporary houses or the government can build it for them. The process was initiated by reviewing the existing designs published previously which were then examined from the perspective and experience of the authors. The next step was defining some basic design criteria by combining findings from literature, author experiences, local conditions and the availability of resources. The proposed conceptual design was then developed based on the design criteria of a temporary house. At the last stage, a prototype of temporary house was constructed as a showcase. This article summarized all these processes which indicated that, to such extent within the boundary condition of the study, bamboo can be practically applied for building a temporary house following earthquake disaster, with a special reference to Lombok Earthquake in 2018.
The seismic responses of RC frames infilled with full and partial masonry walls under cyclic lateral load
Authors: Maidiawati  , Tanjung J
Published: April 2021

This paper presents the seismic responses of full and partial brick masonry infilled frames under lateral load. Four test specimens of ¼ scale-down single-story single-bay, including one RC bare frame, one RC frame with a full brick masonry wall, and two RC frames with partial brick masonry walls were tested under quasi-static cyclic loading. During the tests, initial crack, cracks propagation, and failure processes of specimens were monitored. Lateral forces and displacements in-plane direction at several points on specimens were recorded. Consequently, it was found the differences of seismic responses between a bare frame, fully masonry infilled frame, and partially masonry infilled frames. Installing full or partial masonry infills in the RC frames structure can change the failure mechanism, increase the lateral strength and stiffness, but decrease the ductility performance of the whole structure.

Published: April 2021

This research focused on seismic performance evaluation of earthquake resistant simple landed house using Confined Masonry (CM) structural system which follows technical specifications set forth in regulation of Appendix 2 of Peraturan Menteri Pekerjaan Umum dan Perumahan Rakyat (Permen PUPR) Nomor 5 tahun 2016 (Permen PUPR No. 5 of 2016). The seismic performance evaluation of the structure is performed by conducting strength based analysis using earthquake loading as specified in SNI 1726:2019. Seismic performance evaluation of Unreinforced Masonry (URM) simple landed house was also performed to be compared. Evaluation result shows that CM house prototype which follows the regulation has good seismic performance. Meanwhile, URM house prototype is inadequate to resist earthquake loads particularly on many locations in Indonesia with moderate to high level of seismicity.
