Abstract

In order to achieve production targets for fuel and petrochemical products to support national energy security, reliable equipment is needed to support the operation of petroleum processing refineries. Main equipment such as injection pumps must be able to adapt to the expected operational conditions. Check valve is one of the supporting components of injection pump reliability. Research was conducted to determine the velocity characteristics of two ball type check valve designs using Computational Fluid Dynamics (CFD) numerical simulations. In this research, three variations of pump stroke length were simulated, namely 25%, 50% and 100% with three variations of solid particle size, namely 200, 250 and 300 microns. The fluid that passes through the check valve is a solid-liquid mixture of catalyst and particles. The analysis carried out is by comparing the velocity values as well as the flow patterns produced for each variations used. The simulation results show that of all the variations tested, the model with a stroke length of 100% produces the maximum velocity. In addition, the size of solid particles is inversely proportional to fluid velocity and flow. From the results of this research, it was also found that model 2 has more potential for backflow towards suction, and also model 2 has more potential for clogging because particles that should flow stop inside the check valve.

Abstract

Soil has a very important role in construction, namely in buildings, roads, bridges, dams and other buildings, so soil with adequate technical properties is needed. Work will encounter difficulties if you encounter soil that has large shrinkage characteristics, this causes damage to the building standing on it. To improve the properties of peat soil in the field of civil engineering, soil stabilization is carried out. Soil stabilization is in principle to improve the quality of soil that is not good, or improve the quality of soil that is actually already classified as good. The characteristics of peat soil include: high organic content, easy degradation when exposed to water, and if the soil experiences dryness the soil shrinks. The liquid limit of the original soil was 63.505% and when the lime mixture was added it became 61.46% in a mixture of 5% lime, 53.47% in a mixture of 10% lime, 49.30% in a mixture of 15% lime, and 28.55% in a mixture of lime 20%. The plastic limit of the original soil was 24.03% and when the Gypsum lime mixture was added it became 29.16% in a mixture of 5% lime, 31.11% in a mixture of 10% lime, 34.15% in a mixture of 15% lime, and 36.14% in a 20% lime mixture. As the Plastic Limit value increases and the Liquid Limit value decreases in the soil, the plasticity index of the soil decreases and the cohesive properties of the soil decrease.

Abstract

Pushover analysis is a procedure to determine the collapse behavior of a building in an earthquake. The pushover analysis method is widely used by high-level building planners who rely on performance-based planning. The aim of this research is to become a reference in evaluating the collapse performance and behavior of buildings. This research was carried out using SAP2000 software where the structure was modeled in three dimensions. After carrying out the initial load analysis and stress examination, the analysis results showed that the behavior of the building structure was non-linear. This occurs under conditions of higher loads or significant deformation. So the results obtained in the X direction, the maximum displacement value obtained is 0,014410 m achieved with a base shear of 64.746,662 kN. In step 7, collapse (C) occurs in one of the structures marked with a yellow dot. Meanwhile in the Y direction, the displacement obtained is 0,15 m with a base shear of 58.897,495 kN. Based on the structural performance classification according to ATC-40, both in the X direction and Y direction, the building structure is included in the "Immediate Occupancy" category. This means that the structure is able to maintain its function without experiencing significant damage at the given load level. This level of performance is still well below the “Collapse Prevention (CP) limit, meaning that the structure is considered safe under these conditions.

Abstract

Vehicle electrification is becoming a growing trend in the transportation industry due to environmental concerns. Therefore, various global efforts are being made to develop electric-driven ships using environmentally friendly energy sources such as batteries. In the implementation of electric and solar-powered shipbuilding, there is always the potential for delays in completion. This is very detrimental to shipyard owners and even ship owners because it is not to the initial plan. Shipyard owners and shipowners must bear greater or unexpected costs due to delays in work. Other risks also have the potential to arise when electric and solar-powered ships are completed until operation. Delays in the completion of electric and solar-powered shipbuilding can be caused by various things. Through this research, the risk analysis of the development of the electric and solar-powered ship industry is discussed in terms of several aspects, namely market, legal, technical, socio-economic environmental, and financial aspects.

Abstract

Tanjung Jati B Unit 3 & 4 Steam Power Plant (PLTU) is a steam power plant that uses coal as fuel. Burning coal produces exhaust emissions containing sulfur dioxide (SO2) which is dangerous for the environment. To overcome this, PLTU Tanjung Jati B Units 3 & 4 uses Flue Gas Desulphurization (FGD) to reduce SO2 emissions. This research aims to analyze the factors that cause FGD failure in reducing SO2 emissions, formulate efforts to overcome FGD failure and improve its performance, and develop a method for evaluating the effectiveness of FGD in reducing SO2 emissions. The research method used is literature study, primary data collection through observation and interviews, and data analysis. The research results show that the factors that cause FGD to fail in reducing SO2 emissions are blockage of the spray pipe and header pipe, blockage of the tray, and a decrease in the performance of the booster fan and absorber recirculation pump. The method for evaluating the effectiveness of FGD in reducing SO2 emissions is by analyzing de-Sox efficiency, flue gas flowrate and temperature, pressure drop, and ARP discharge pressure. Keywords: PLTU, FGD, SO2 emissions, de-Sox efficiency, flue gas flow rate, pressure drop, ARP discharge pressure. The method for evaluating the effectiveness of FGD in reducing SO2 emissions is by analyzing de-Sox efficiency, flue gas flowrate and temperature, pressure drop, and ARP discharge pressure.

Abstract

This research is part of an effort to solve waste management issues in Sleman Regency, focusing on measuring and evaluating the Zero Waste Index (ZWI) in the Green Open Space (RTH) Denggung, Sleman. The resource substitution method was used to assess the efficiency and potential for waste reduction in the area. Based on field data and calculations using the ZWI formula, it was found that the ZWI value in RTH Denggung is very low, only 0.14, meaning that only about 14% of resources are recovered from the waste management system. This indicates that waste management in the area is not yet optimal, necessitating improvement and innovation efforts. The proposed strategies include enhancing the recycling of plastic, paper, and styrofoam waste, as well as developing composting for food scraps and other organic waste. The implementation of stricter policies related to waste management, public awareness campaigns, and the integration of zero waste initiatives are expected to improve the ZWI value. This effort is hoped to be part of the solution to waste management in Indonesia and serve as a best practice example for waste management in RTH or other public spaces..

Abstract

The current technology for using recycled materials in road preservation work is very helpful in maintaining the sustainability of the materials used. Waste from road materials that will be repaired can be reused for new foundation layers. The aim of this research is to obtain a design for the percentage of cement, percentage of emulsified asphalt, unconfined compressive strength and optimum water content in accordance with the applicable engineering specifications so that it can be proven that the existing material from the top foundation layer and asphalt layer can still be used as a new foundation layer. The research method involves conducting experiments on existing materials by conducting laboratory tests on samples of top foundation layer aggregate and existing asphalt in the Cikarang Industrial Area. The experiment was carried out at the Jakarta State Polytechnic Civil Engineering Laboratory with 9 test samples. The results obtained for the recycled foundation layer were that the design cement required was 30.8 grams and 53.1 grams of emulsified asphalt for an area of ​​1m2 with a 7 day unconfined compressive strength obtained from nine samples for variations in cement content of 1%, 3%, and 5% maximum 2.81MPa, so the optimum cement content is 3.6%.

Abstract

The Indonesian government is enthusiastic about continuing the biodiesel program as one of the new and renewable energy mandatory programs which has proven to be able to provide many benefits ranging from achieving environmentally friendly energy, saving state foreign exchange, increasing energy security, to providing jobs; in line with the 7th principle of sustainable development goals (SDGs). In fact, the Indonesian government has increased the B30 Biodiesel program in 2020 to B35 in 2023. It is supported by the Palm Oil Plantation Fund Management Agency (BPDPKS), which has the authority to collect CPO export levy funds and redistribute them to biodiesel producers, so that they can produce biodiesel economically. With this mechanism, the Biodiesel program can be implemented even though the price of biodiesel is more expensive than fossil fuels, but does not burden the State Budget (APBN). However, this program is difficult to increase, because the availability of incentive funds is limited by the amount of CPO exported and the amount of the levy. The Ministry of Energy and Mineral Resources (ESDM) must find a way for the biodiesel energy program to achieve the 23% energy mix target in 2045, and not rely on export fund levies anymore.
