Abstract

Hydropower with a cascade scheme utilises the energy potential of water in a sustainable manner. The Brantas River area is used to generate 4 (four) hydropower plants (HEPP) that are arranged in series from upstream to downstream, namely Sengguruh HEPP, Sutami HEPP, Wlingi HEPP and Lodoyo HEPP. From December 2022 to November 2023, the four hydropower plants can produce 888,629,472 kWh of electricity. However, there is still potential for electricity generation that can be optimised from the unused water potential (spillwaywater) of 553.61 million m3. The optimisation management system provides a solution for utilising water energy sources by formulating a mathematical model using Solver in the Microsoft Excel application to plan the water level of the Sutami reservoir, hydropower load settings and peak/off-peak times at each hydropower plant. By implementing an optimisation, electrical energy production has the potential to reach 951,796,287 kWh or an increase of 7.11% in the period December 2022 to November 2023 by minimising the occurrence of spillway water by up to 92.40% or 551.61 million m3. As a result, the cascade efficiency of the hydropower plants of the Brantas River cascade was increased by 2.87% or 0.003 kWh/m3.

Abstract

Composite is a group of materials made from 2 or more materials and strengthened by certain treatments. To strengthen the composite, it can be done through Alkalization treatment, meaning that the fiber is soaked in a NaOH solution for a specified time to clean the surface of the fiber so that it will increase the cellulose content by reducing the lignin and hemicellulose content. Apart from alkalization, increasing the strength of the composite can be done by treating the layout of the fiber orientation and volume fraction. The research results show that the average impact price for water hyacinth fiber composites is water hyacinth fiber composite with a volume fraction of 30; 70 and 50 : 50, namely for volume fraction 30 : 70 is continuous vertical orientation: 2, 84 joules/mm, continuous horizontal orientation: 1.44 joules/mm, random orientation: 1, 88 joules/mm then for volume fraction 50: 50 is continuous vertical orientation: 3.69 joules/mm, continuous horizontal orientation: 2.26 joules/mm, random orientation: 3.1 joules/mm. From the data that has been obtained, it shows that the most optimal impact value is in the fiber orientation. continuous vertical with a volume fraction of 50 : 50, namely 3.69 joules/mm. In this study the volume fraction was 50; 50 has the highest impact price, fiber volume greatly influences the results of the impact test

Abstract

ABSTRACT Knowledge about technology will continue to develop by itself through individual thoughts, the rapid progress of science and technology opens up thoughts and ideas in forming materials and even modifying them, which in general the frame or chassis of vehicles uses steel, steel is very heavy compared to aluminum. but changing a material will cause a lack of safety and comfort because aluminum is known to have a very low level of strength when compared to heavy metals. So carbon fiber was added to the surface of aluminum 6061 with carbon fiber thicknesses of 4 mm, 8 mm and 10 mm, in fiber directions of 45o and 90o by carrying out impact testing and bending testing to see the strength of the material when loaded. T The presence of 45o and 90o fiber directions slightly affects the maximum load on 6061 aluminum with a woven carbon fiber layer, where the average value in the 45o direction is 90.7 and 90o 80.8. However, by reducing the thickness of aluminum 6061, it reduces the bending strength value of the specimen due to the lack of moment of inertia, the coating specimen also appears to be coming off due to the lack of adhesion of the carbon fiber webbing to aluminum 6061. The attachment process is influenced by the hardness of the specimen so that the rougher the material structure, the higher the coefficient. high friction, Keywords: Aluminum 6061; Carbon Fiber; Impact Test; Bending Test.

Abstract

PT XY, a precast concrete manufacturer, especially for electric poles, faces product quality problems in the form of defects, which harm quality, management, and production costs. This study aims to identify the root causes of defects and provide improvement solutions using the Seven Tools and Failure Mode and Effect Analysis (FMEA) methods. FMEA is used to identify potential and risk of failure and to formulate priority improvement actions. The results of the study showed three main types of defects: porous fins (53.53%), skin sticking (39.56%), and mottled (6.92%). The causal factors include methods, materials, humans, and machines/tools. FMEA analysis produces the highest Risk Priority Number (RPN) for porous fins (192) caused by imprecise molds (machine/tool ​​factors). The recommended solution is to inspect and repair the moulds periodically. Skin sticking defects have an RPN of 210, caused by poor oil quality (material factors); replacing the oil with an oil-based type is the solution. Mottled defects with an RPN of 144 are caused by the low slump of the casting mixture; the solution is to guide the mixing of raw materials according to standards. This study provides specific recommendations to reduce defects in electric pole products at PT XY, focusing on mould improvement, replacement of oil types, and standardization of raw material mixing.
