Abstract

The "EPC Talavera" Tuban Project is one of the major projects located in Tuban. Given that the construction of the Blending Silo is being built at a considerable height and certainly requires a large foundation structure, the construction of the Blending Silo carries a relatively high risk of workplace accidents. The purpose of this research is to identify workplace accident risks and evaluate the causes, impacts, and risk responses to accidents during the construction of the substructure of the Blending Silo in the "EPC Talavera" project. To determine the dominant workplace accident risks, risk assessment is performed using probability and severity calculations based on the Risk Management Standard AS/NZ 4360:1999, resulting in an Importance Index value. The method used to evaluate the causes, impacts, and risk responses to workplace accidents is the Bowtie Analysis Method. The results of this research indicate that the most dominant workplace accident risks are the risk of workers being pierced by sharp equipment, the risk of fingers getting caught in the bar bender machine, and the risk of workers being shocked/electrocuted by electrical currents. Based on the bowtie method, the most dominant causes of workplace accidents are scattered sharp equipment, careless/inattentive/unhealthy workers, inadequate equipment, poor bar bender machine conditions, bar bender machine operating methods, exposed welding tool cables, rainy/extreme weather conditions, and electrical current leaks in welding tool bodies. The most dominant impacts of workplace accidents are minor injuries, serious injuries/death, fires, and damage to the bar bender machine. Using the bowtie method, risk responses or controls for the most dominant workplace accident risks are also analyzed, along with an analysis of escalation factors and their controls.

Abstract

Surakarta City often floods when there is high rainfall, according to BNPB 2016 three consecutive days of rain can cause flood disasters. Hydrological analysis is needed to determine the flood discharge due to the maximum three-day rain. With the development of TRMM satellite rain data technology can be used in hydrological analysis to overcome the problem of limited data availability at rainfall gauges. The purpose of this research is to determine the value of discharge, inundation area caused by a maximum of three days of rain. In addition, this research also evaluates flood events and determines appropriate efforts in overcoming floodwater runoff by installing parapets. The use of HEC-RAS software in this research is for flood analysis and simulation of parapet installation in areas experiencing river water runoff. The calculated flood discharge is the annual flood discharge from 2000 - 2019. The method of calculating the discharge uses HSS Gama 1. Then flood tracing is carried out to determine the area of inundation that occurs. The process of mapping and determining the extent of flooding that occurred in each sub-district was carried out with the help of software GIS. The highest flood area due to river runoff occurs in Laweyan Subdistrict, which is 45,80 ha. From this location, a parapet installation simulation was carried out as one of the flood mitigation efforts. Simulation of parapet installation was carried out in Pajang Village and Laweyan Village, after simulating parapet installation, the flood area for Laweyan Subdistrict was 2,21 ha.

Abstract

The issuance of Circular Letter from the Director General of Highways No. 04/SE/Db/2017 With the revision of the 2017 Pavement Design Guidelines, the old flexible pavement design rules no longer apply. However, in some regions, the old Component Analysis guidelines for pavement thickness planning are still being used. This study aims to compare the flexible pavement thickness between the Component Analysis method and Bina Marga 2017. The data used in both methods are the same. The analysis results show differences in pavement thickness between the two methods. The pavement thickness according to the Component Analysis method is as follows: surface layer thickness (D1) = 74 mm, upper foundation layer thickness (D2) = 200 mm, and lower foundation layer thickness (D3) = 250 mm. Meanwhile, the MDPJ 2017 method gives the following thicknesses: surface layer thickness (D1) = 100 mm, upper foundation layer thickness (D2) = 400 mm, and lower foundation layer thickness (D3) = 100 mm. A significant difference between Component Analysis and MDPJ 2017 is that the Bina Marga 2017 method does not take regional factors into account. It assumes that the road drainage system functions properly and there is no water pooling on the road. The smallest load on the road is a 2-ton vehicle, so motorcycles are not considered a load on the road. If the MDPJ 2017 method is used for road planning in areas where the majority of vehicles are motorcycles, it will result in higher implementation costs compared to Component Analysis. In general, the pavement structure according to Bina Marga 2017 is thicker compared to the Component Analysis method, and the CBR value and the number of vehicles are the main parameters in road pavement thickness analysis for both methods mentioned.

Abstract

Indonesia is a country with a high potential for earthquake risk, therefore every building must be designed in such a way, so the impact of damage caused by an earthquake can be minimized. Each Existing building structure also needs to be analyzed for its performance against earthquake loads. The main rule in designing an earthquake-resistant building is that structural elements may be damaged but must not fail or collapse during a strong earthquake. This study aims to analyze the performance of building structures based on FEMA 356 standards, by taking a case study of the structure of Tower A of Pembangunan Jaya University. The method used is the pushover analysis method using the Etabs V.16 application. The results of the nonlinear static analysis produce an output value which is then calculated using the FEMA 356 standard. The results of the analysis show that Tower A of Pembangunan Jaya University, which is an open frame structure made of reinforced concrete, has an Immediate Occupancy performance level, which means that if the structure is hitting by an earthquake with return period of 50 years, the building has no significant damage to the structural components. The stiffness and strength of the building is almost the same as before the structure was hit by the earthquake. Meanwhile, the building has a displacement value of 0.383 meters, this value is still smaller than the displacement value based on FEMA 356 calculations which is quite large, namely 0.618 meters in the x direction and 0.542 meters in the y direction.

Abstract

Drought occurs quite often in Indonesia, closely related to water availability for community needs. One of the districts in West Java Province experiencing drought problems is Karawang district, where the RWH (Rainwater Harvesting) concept will be applied. This study aimed to analyze the risk of drought-related to applying the potential RWH in reducing drought risk. This study only focuses on meteorological drought, determined by SPI (Standardized Precipitation Index). Identification of potential areas for the application of RWH is carried out using the Weighted Method Overlay approach in the Geographic Information System (GIS), which was modified by adding a parameter of potential drought hazard. The potential reliability of RWH, as seen from Volumetric Reliability (VR) for supplying the average water requirement of MCK (Bath Washing Toilet) per year, indicates that most of the Karawang district area is potential for applying RWH. The results of adding the potential drought hazard parameters on applying the RWH concept show the decreasing area of very potential and potential category areas into 5,38%, the increase of drought resistance capacity is 17.5%, and the risk-reducing to 8.3%. Those results are due to the changes in the area of drought in the risk analysis. The assumptions of 60 rainy days on the average rainy day in a year and all households making RWH storage systems were used in the analysis. The results of this study can be used as a first step to see the potential of RWH in Karawang Regency both in terms of area and reliability.
