Abstract

Composite is a combination of materials consisting of 2 or more materials lead to the composite material has different mechanical properties and characteristics as desired. Composite materials are divided into two types, synthetic fibers and natural fibers. Most of the natural fiber types use jute fiber, as it is a candidate as a reinforce material to produce lightweight, strong and environmentally friendly composite materials as mixing polyester composites. Although composites can be made according to the desired shape, the final work, such as the machining process, is also needed for making several shapes such as making holes with the drill process. Furthermore, twist drilling, can induce damage due to the imperfections of the holes that are produced, resulting asymmetrical holes. This allows complicate assembly and reduce its strength. The parameters use are spindle speed 100 rpm, 700 rpm and 1400 rpm and feeding 0,1 mm/rev, 0,2 mm/rev, 0,3 mm/rev, 0,5 mm/rev and 0,7 mm/rev. The results obtained that using 100 rpm and feeding 0.5 to 0.7 can make imprecise and resulted delamination of the hole. Increased spindle speed such as 700 and 1400 rpm and higher feed rate, resulted increase the accuracy of the hole

Abstract

A composite is one of the materials that is a mixture of two or more materials to form a third, more useful material. In this study, researchers chose bamboo fiber and iron sand as reinforcement for composite materials because the selection of bamboo fiber as a research material took into account the potential of bamboo fiber in Indonesia which is abundant and has not been utilized properly. The purpose of making bamboo fibrous composite materials aims to find a material that is lighter stronger and more elastic, can be developed into other products such as the manufacture of drone frames, aircraft bodies, brake pads. The method used is an experiment with making specimens using the hand lay up method and testing using impact testing and micro photo testing. Impact testing is used to determine the properties and characteristics of the material in the form of strength, hardness, and ductility of the material while for micro photos it is used to determine the bond of the material composition with the best impact test. The test standards used are ASTM D6110-10 with random fiber arrangement and ASTM D6110-04 with the arrangement of woven fibers, with variations in volume composition of bamboo fiber and iron sand particles. In the D6110-10 specimens, the best specimens were found in the variation with the most bamboo fibers, namely 35S10 P with an impact energy of 4.27 J and an impact price of 0.04 J / mm2, while the lowest variation was found in the most iron sand, namely 35P10S with an impact energy value of 2.26 J and an impact price of 0.02 J / mm2. In the D6110-04 specimen also showed the same characteristics as the ASTM D6110-10 specimen, the 30S30P variation or the composition of the most bamboo fibers had an impact energy value of 4.09 J while in the 10S10P variation it was only 1.47 J. Thus the more bamboo fibers will make the impact strength of the specimen higher.

Abstract

The low demand for vocational education graduates has led to high unemployment. The low demand for vocational education graduates has led to high unemployment. Vocational college graduates still need to be commensurate with industrial needs. Many Senior High School, Vocational High School, and Vocational College graduates have not been able to find a job for more than six months. Conditions on Madura island worsened this, and the lack of accelerated industrialization even after the Suramadu Bridge was built. Madura has the lowest Human Development Index (HDI) score in East Java. Data from the Central Bureau of Statistics (BPS) Sampang in Figures 2021) shows that the HDI value in 2020 only increased by 0.76 from 2019 of 62.70. Politeknik Negeri Madura (Poltera) together with PT. United Tractors and LSP ABI want to take an active role in improving Madura's HDI by preparing human resources on heavy equipment mechanics through the development of a centre of excellence for technology (PUT) of Heavy Equipment (CHE). Using the causal-comparative method, the researcher observed the impact of each stage on PUT-CHE development activities and reviewed the data to find causal factors and correlations. Poltera took a strategic step by equipping lecturers with virtual training on heavy equipment mechanics (SOBAT Program), organized by PT United Tractors. The SOBAT program has positively impacted heavy equipment engineering graduates in 2022, which has increased significantly. Academic data showed that 13 out of 34 heavy equipment mechanical engineering graduates were employed in leading heavy equipment industries before three months. Other data stated that three lecturers participating in Virtual Training on heavy equipment mechanics were selected as 50 interns at PT United Tractors.

Abstract

A biomass co-firing program has been put in place at power plants by PLN to support policies relating to the renewable energy mix. The extent to which continuous biomass co-firing at various generating load conditions will affect the performance of boiler equipment is unknown. The goal of this study is to ascertain the effects of ongoing biomass co-firing on the efficiency of boiler equipment under various generating load scenarios. An observational approach as well as interviewing techniques were used to collect the data. By hand, using Microsoft Excel software, the calculation value for a specific fuel consumption and net plant heat rate is found. The operating parameters of the boiler equipment performance are then compared with benchmark or commissioning data. The performance of boiler equipment (medium speed mill, boiler fan, air preheater) is unaffected by the co-firing process, and all of its parameters remain within acceptable bounds. As can be seen from the Mmdium speed mill motor and boiler fan flows, which decreased but not significantly, the performance of boiler equipment during the co-firing process is lighter. There is a decrease in boiler furnace temperature despite changes in load, and boiler equipment performance is still within limits. The average total production cost dropped from 485.324 Rp/Kwh to 484.585 Rp/Kwh with co-firing. During the course of the study, the average Net Plant Heat Rate during the co-firing process fell from 2862.85 kcal/kwh to 2866.35 kcal/kwh.

Abstract

The use of steam compression refrigeration systems is growing both domestically and commercially. The impact of electrical energy consumption in this sector is quite large compared to the need for electrical energy in other electronic equipment. Various efforts were made to be able to reduce the consumption of electrical energy for the cooling system. One of the efforts made by utilizing the natural potential of energy around is solar energy as a source of electrical energy in the mango freezing unit. This fruit is one of the main commodities in West Java, especially in Indramayu Regency. This study aims to determine the performance of the use of solar energy and the need for electrical energy for freezing mango fruit. In the process, freezing is carried out at temperatures below the freezing point of the ingredients/food. Good freezing usually ranges from -12 oC to -24oC. With this temperature, food can last up to 3 to 12 months. Although for freezing mango fruit, it is necessary to have additional treatment so as not to damage the physical structure and quality of the fruit. The method used is to use solar panels as a source of electrical energy in the mango freezing unit. From the tests carried out with variations in the tilt angle of the solar panels, 0°, 20°, and 40° which then from the calculation analysis it is known the comparative value of performance/efficiency and also the consumption of electrical energy generated from each angle of inclination
