Malang has a projection population of 861,414 people in 2018. This big population would cause waste generation that is increasing every day. Waste generation was recorded at the amount of up to 646.07 tonnes/day just from Malang in 2018. However, waste transported to landfill was only 516.84 tonnes/day. It means that the load factor was only 84.73%. Waste transportation problems come from various factor. Malang had only 68 temporary waste storage (TPS) that were spread in the city. This number of TPS was not commensurate with waste generation that was generated every day. The limited number of trucks was another issue considering Malang only had 35 trucks capable of making three trips per day. Limited number of trucks and TPS has led to a bad situation for transporting waste. As a result, many wastes were left behind in TPS. Therefore, it is necessary to analyze the best route for the trucks sso that the waste route can be optimized using network analysis in ArcGIS. This study assessed one route of a truck which had the longest distance (TPS Tunggul Wulung) with a total of 60.2 km at a time that it reached in 113.8 minutes. The result of the network analysis method with ArcGIS showed that the total distance declined to 36.2 km. This indicates that the alternative route shown by the shortest distance method has been able to reduce the existing distance for waste transportation route by 24 km. This certainly resulted in the decline in travel time for ± 39 minutes/day. This indicates that the existing routes can be optimized by alternative route network analysis in ArcGIS.

Eccentrically Brace Frame system develops its ductility using link inelasticity. Therefore, the strength of the structure in resisting the lateral force is highly dependent on the link and some types of link that are commonly used. Furthermore, it needs to compare the behavior of two section frames that most commonly used as a link in EBF system building; they are WF section and tubular section. In addition to the cross-sectional factors, deformation of the link is also highly dependent on the length of the link, hence the test will also be done on three different type of link lengths, they are short links, intermediate links, and long links, that are according to the classification of link lengths defined in AISC Seismic Provision. Before starting the analysis, a literature study has been reviewed to learn more about the behavior of a link under cyclic load. The numerical analysis has been done to find the strength of the link and modeling with the Finite Element Analysis (FEA) using ABAQUS. After all analysis and the calculation are completed, the results will appear in three-dimensional modeling form, Displacement versus Force diagrams and the stress-strain curves to show the ductility of all specimens. The result of the study showed that in short links, both WF link and tubular link achieve nominal shear force is equal to V p plastic shear force with values 390 kN for tubular section and 437 kN for WF section, and the value of shear force to the classification of the short link is very dependent on the body cross-sectional area. Tubular link's body with an area of 89% of the WF link total weight generates shear forces 89% of the shear force from WF link because the formulation of the plastic shear force V p is highly dependent on factors of body cross-sectional area (A w ). According to the research result, it shows that for both WF and tubular link cannot reach nominal shear force when the length of the link over the requirement of the shear link.

Effect of bond coat and preheat on the microstructure, hardness, and porosity of flame sprayed tungsten carbide coatings AIP Conference Proceedings 1855, 030016 (2017) and the ratio of height to width of 1 to 1.5. Load used in the experiment was based on Uniform Building Code (UBC) 1991. Every method compared was calculated first to get equivalent diagonal strut width. The second step was modelling method using structure analysis software as a frame with a diagonal in a linear mode. The linear mode was chosen based on structure analysis commonly used by structure designers. The frame was loaded and for every model, its load and deformation values were identified. The values of load -deformation of every method were compared to those of experimental test specimen by Mehrabi and open frame. From comparative study performed, -equations gave results the closest to the experimental test specimen by Mehrabi. Other equations that gave close values within the limit (by comparing it to the open frame) are

This article presents about vulnerability assessment of high-rise building in Surabaya, the second largest city in Indonesia. In 2007, the Earthquake National Research Center -Indonesia’s Ministry of Public Works released the latest earthquake fault map. Include the discovery of Surabaya fault and Waru fault that across Surabaya. According to that new discovered fault, it is possible that there is a higher potential earthquake hazard for buildings structures in Surabaya. Therefore, the efforts to assess the vulnerability of buildings towards the earthquake need to be conducted, especially for the high-rise buildings. An android based RViSITS (Rapid Visual Survey by Institut Teknologi Sepuluh Nopember) is an application that has been developed based on FEMA 154. That application helps the vulnerability assessments of buildings can be conducted quickly and efficiently. Since, it does not require a lot of personnel, quite short research time and cheaper cost than having to use a manual form that is considered less effective for a large number of buildings. This research itself is conducted to assess the vulnerability of high-rise buildings (8-15 floors) throughout Surabaya city using the RViSITS android application. Based on the results of this study on 98 high rise buildings, it is found that 21 buildings (21.43%) are in the prone category since they had an index value < 2, while 77 buildings (78.57%) are in the safe category with an index ≥ 2. The result obtained in this research can be used as a database of local government institution for mapping the vulnerability of high rise buildings and initial input for mitigation plan toward the higher possibility of an earthquake hazard in Surabaya.
