Abstract

Bentonit merupakan salah satu bahan utama dalam cetakan green sand dan berpengaruh pada karakteristik cetakan serta hasil benda cor. Kadar bentonit mempengaruhi permeabilitas, kompaktibilitas, kekuatan geser, dan kekuatan tekan cetakan green sand. Tujuan penelitian ini adalah untuk mengetahui perubahan karakteristik cetakan greensand akibat perubahan kadar bentonit serta pengaruhnya terhadap cacat inklusi pasir. Variasi kadar bentonit sebesar 3,5 % dan 4,3 % dari berat total bahan cetakan. Pengujian cetakan mencakup uji mampu bentuk, kekuatan tekan, dan kadar air. Uji coba pada benda cor disc brake mobil untuk menganalisa pengaruhnya terhadap cacat cor yang terjadi. Hasil pengujian karakteristik cetakan green sand menunjukkan bahwa kadar bentonit 3,5 % memiliki mampu tekan cetakan 13,7±0,4 N/cm2 (standar : 14 – 18 N/cm2) dan mampu bentuk cetakan 34±5,1 % (standar: 33 – 58 %). Kedua karakteristik ini masih berada di bawah standar cetakan green sand. Kadar bentonit 4,3 % memiliki karakteristik cetakan yang sesuai dengan standar cetakan green sand untuk semua karakteristik cetakan yang diuji. Hasil pengecoran besi cor nodular menunjukkan terjadinya cacat inklusi pasir pada benda cor. Kekurangan kadar bentonit menurunkan mampu bentuk cetakan sehingga cetakan mudah rontok ketika cairan logam masuk. Rontoknya cetakan ini dapat membawa pasir sehingga terjadi inklusi pasir pada benda cor. Demikian halnya dengan mampu tekan cetakan yang di bawah standar. Kekuatan tekan rendah memungkinkan cetakan erosi ketika terkena tekanan cairan logam.

Abstract

Gresik Regency's coastal Bawean Island is where Sangkapura District is situated. In 2020, there were 117,112 power consumers in the Sangkapura District. On the same island, there have been some regions without electricity daily. This demonstrates that there is still a need for electrical energy, which is growing along with the population. Additionally, growing global oil prices are a sign of the need for electrical energy. Fossil energy, which is non-renewable and can produce emissions, is the energy source that is most frequently used today. An energy crisis can be brought on by the excessive consumption of fossil fuels. The suggested remedy is to employ new renewable energy (EBT) as a source of electrical energy, taking into account that EBT is more environmentally friendly. Therefore, more study is required to determine the local potential of wind as a wind power plant (PLTB) using vertical axis wind turbines, taking into account the benefits and drawbacks of each type of turbine. The analysis of published works and the Meteorology, Climatology, and Geophysics Agency's online database is the research techniques used. According to the analysis, an average wind speed of 1.5 m/s and wind power of 10.47 watts were measured. Dim LED lights can be turned on with this amount of energy. Sangkapura District has a poor potential for wind power plants because this number is lower compared to numerous pertinent research and employs a home size. Therefore, we require a different strategy that can utilize low wind speeds to generate electricity.

Abstract

UHMWPE (Ultra High Molecular Weight Polyethylene) is a unique polyethylene material widely used in biomedical applications as a bearing material for human body joint implants. The production of these UHMWPE implant components is still commonly performed with machine tools. Operation of these machines requires specific setting machining parameters in order to produce good UHMWPE surface quality without sacrificing the production cost. This research aims to find the relationship between cylindrical lathe machining productivity parameter, MRR (Material Removal Rate), and surface quality of the produced UHMWPE implant. MRR is directly related to production costs. The research was conducted by turning the UHMWPE at five feed rate variations between 0.025 to 0.2 mm/rev. and two depth of cut variations, 0.05 mm, and 0.1 mm, with a cutting speed of 150 m / minute. The test used a Denford FANUC CNC lathe machine with a cemented carbide cutting tool. Product quality was determined by measuring the topography or surface roughness of the material. Results show that the surface quality is inversely related to MRR. This problem can be solved by adjusting the depth of the cut. High productivity can be obtained by cutting thicker material. The difference in the surface quality of the cylindrical lathe machined material in the two depth of cut variations is not significant.

Abstract

Glass Fiber Reinforced Polymer (GFRP) in train interior components must have good fire resistance properties. Therefore, it is necessary to add a flame retardant compound to the GFRP material. In this study, Alumina Trihydrate (ATH) and Melamine Cyanurate (MCA) were mixed into a vinyl ester resin. The method of making GFRP refractory specimens uses the hand lay-up method. GFRP is mixed and tested for fire resistance standard ORE B 106.2. The results obtained after the addition of 25% ATH, a mixture of 25% ATH with 5% MCA, 10% MCA with 25% ATH, and 15% MCA with 25% ATH, 25% ATH in the outer layer, and a mixture of 5% MCA with 25% ATH in the outer layer of the resin weight is able to increase fire resistance. Optimum GFRP fire resistance at the addition of 25% ATH to the weight of the resin in the outer layer. The result of the burned area is 84.84 cm² with a fire extinguishing time of 0.33 seconds after the fire source leaves the specimen. The results show that the mixture of ATH and MCA has a synergistic effect on fire resistance properties, so it becomes a recommendation for interior sidewall panels and ceiling panels on trains according to the ORE B 106.2 standard
