Abstract

Analisis menggunakan metode Finite Element menghasilkan data secara menyeluruh dan detail. Respon fisik sistem terhadap beban di beberapa titik mampu terbaca. Hal tersebut sangat berguna dibidang engineering, terutama pada kendaraan dan analisis struktur. Penelitian ini bertujuan untuk mencari nilai tegangan, regangan maksimal serta displacement dengan pembebanan statis dari struktur rangka pad akendaraan listrik roda tiga. Kendaraan listrik roda tiga yang digynakan diharapkan memiliki kapasitas beban angkut yang besar sehingga simulasi ini sangat diperlukan. Hasil simulasi menunjukkan bahwa nilai tegangan maksimum pada rangka sasis ketika diberi beban 1500 N adalah 0,0244 MPa serta 5,26×10-13 dan 1,27×10-7 untuk regangan minimum dan maksimum. Sedangkan nilai displacement yang didapat adalah 6,208×10-4 mm. Dari hasil tersebut dapat dismpulkan bahwa struktur rangka sudah cukup baik dalam menahan beban yang diberikan.

Abstract

Science and technology are currently developing in all fields, such as vehicle construction, building construction, industry, and materials engineering. Especially in the field of material engineering used for the manufacture of composite materials. Currently the transition of materials from metal to composites is also in great demand in various fields including in the automotive, transportation, shipping, aerospace, health, and various other fields. In the components of a vehicle, the components that have the most potential to be reduced are the main structural components, namely the floor, body, and ribs. Efforts to reduce the weight of the material in these components are carried out to reduce the amount of fuel consumption, so the ratio of strength and density of a material is one of the important properties that needs to be considered. This study used the hand lay up method with a comparison of volume fraction variations of 15%: 85% and 20%: 80%. With the aim of adding volume fractions with optimal combinations, it is hoped that the tensile strength will get better. The highest average tensile strength is with a volume fraction ratio of 15%: 85% of 19.04 MPa. While the lowest average tensile strength is with a volume fraction ratio of 20%: 80% of 17.78 MPa. It can be concluded that with increasing fiber volume fraction, the tensile strength decreases. This happens because there are several defects in the form of holes and voids which indicate poor bonding between the fibers and the matrix.

Abstract

Locations with hard-to-reach access make people living in 3T (Terluar/Front, Terpencil/Remote, Terbelakang/Backward) areas unable to enjoy quality fuel oil (BBM) at affordable prices. This research provides solutions for people in remote areas and communities in the 3T area to utilize agricultural equipment without dependence on fuel. The agricultural equipment in question is a Multifunctional Portable Tractor driven by an electric motor, using a battery. Batteries are recharged from solar sources through solar panels, water turbines and wind turbines. The research method used adopts the "Walter Franco" method (Franco et al., 2020). Product design and development involved 3 farmer groups from 3 different regions in West Java and six small machinery component industries in West Java, Indonesia. Research methodology involves the use of observations and field testing prototypes as instruments. This research resulted in innovative equipment that can be used for sloping land farming. This equipment is the only mechanical agricultural equipment that can be folded and carried by one person, so its contribution to research in inclined land farming is very large. This equipment is proven to cultivate land on sloping land profitably, so its contribution to farmers in Indonesia and other countries will be very significant Keywords: Carrying tractor, Electric drive, 3T, Sloping land, Agricultural mechanization

Abstract

Noise is a sound that causes sound violence and disturbs humans. In the aviation industry, noise affects flight safety and success because it can interfere with the concentration and performance of flight cadets. In addition, high intensity can also cause stress and fatigue in flight cadets, reducing their ability to maintain focus and respond to critical situations. This study aimed to analyze the impact of noise produced by engine sounds and radio signals on pilots. The results of this study on the aircraft dashbord sound noise value is greater because the aircraft dashbord clan is located adjacent to the engine while the smallest noise value is found in data retrieval in the back seat because it is farther from the engine. The data collection carried out produces output in the form of data resulting from the effect of engine noise on cadets. Keywords: noise,cadets,engine sound

Abstract

Along with the increasing number of motorized vehicles and the massive renewal of it, their lifetime has become faster, especially for cars. The problem often occurs in cars that have passed their lifetime is a lighting system, one of which is that the car's light socket often melts. Car headlight sockets made of plastic and rubber which function as seals cause the socket to melt when exposed to heat. Based on the existing problems, the purpose of this research is to find new material for making car light sockets using the standard hot wire method. The production begins with mixing epoxy resin with hardener using the hand lay-up method with a ratio of 2:1. Stir mixture for 5 minutes and add the pineapple into molds (110x60x20) mm and wait for a day at room temperature. Furthermore, the thermal conductivity test using QTM-500 tester. Based on the research results, all specimens suitable for the requirements use as materials for making car light sockets, because the thermal conductivity values of all specimens (0.2231, 0.2061, 0.2249) W/mK were below the thermal conductivity values of the previous socket-making materials, 0.23 W/mK. The best specimen composition is specimen 1 with thermal conductivity value of 0.2231 W/mK. This is because specimen 1 has little porosity or voids and small conductivity value. Thus, the composition ratio that is best used in the manufacture of car light sockets based on the total mass of resin, hardener, pineapple fiber, and sodium silica is 15: 7.5: 1: 3.75. Keywords: composite, pineapple fiber, thermal conductivity, socket, catalyst
