Abstract

Rapid development of the automotive world, especially in the two-wheel motor vehicles, must also be compensated with fuel efficiency. Many ways has been used to save fuel for vehicles, particularly for two strokes (2t) gasoline motor, that uses YEIS (Yamaha Energy Induction System) technology, or known as tube Induction. This technology in general is used in Yamaha motorcycle engine with cylinder volume ranging from 155 cc, 135 cc, 150 cc to 250 cc. However the application of YEIS tube is not optimal. The goal of this research is to optimize the performance of the system by creating a system with valve mechanism to regulate incoming and outgoing flow of the mixture of fuel-air into the YEIS system. Induction tube acts as a buffer for fuel-air mixture preventing the mixture from returning to the carburetor during process strokes and then dispose of the rinse proceed with steps, so that the remaining fuel is not futile. The research was started with constructing induction tube, valves and valve housing, assembling and testing. The results of this research indicates that two-wheeled vehicles using an induction tube efficiency has better fuel efficiency than two-wheeled vehicle without induction tube and two-wheeled vehicle equipped with induction tube without the valve mechanism. The result also indicates that the acceleration of the vehicle is not reduced.

Abstract

The manufacturing industry is one of the sectors that consistently continues to provide the largest national economic growth contribution to reach the target economic growth of 5.3% in 2020. In the 4.0 industry era, the manufacturing industry sector in Indonesia starts to adopt the newest digital technology like artificial intelligence, machine learning, and the internet of things, and additive manufacturing. This research aimed to develop a manufactured product in form of Aluminium cylinder head engine prototype with digital rapid prototyping and Aluminium investment casting. To reach the research goal, the research started from theoretical study and data collection. Next, the cylinder head engine is modelled in CAD (computer-aided design software and printed in 3D printer with polyvinyl butyral and polylactic acid. This 3D printed cylinder head is going to use as moulding pattern. Hereafter, the cylinder head engine is assembled with gating system and coated with a mix of cement plaster, silica sand, and kaolin soil. After the mould is dry, the mould will be burned until the 3D printed pattern is vaporized. The final step is pouring the molten Aluminium at 800°C temperature into the mould. The results showed that the casting process with a cylindrical gating system was perfectly formed, especially for the fins part. However, for the smaller fins, there were still defects in form of lumps. The mix of silica sand, gypsum cement and kaolin soil can create a strong mould. The difference in pattern material does not have a significant effect on the investment casting mould-making process.Keywords: Rapid prototyping, cylinder head engine, investment casting.

Abstract

Digital prototyping is an innovative design method. With digital product prototyping techniques that are designed with the concept of Generative Design and Topology Optimization, the designer able to visualize and simulate the product start from the design, stress analysis to the product manufacturing process. The aim of this research is to optimization the topology of the product model results of generative design, determine the strength of the model through Stress Analysis used topology optimization 50%, 60%, and 70% of the product model results of generative design and figure the results of the product 3D printing in made prototype models as a result of generative design. This research is conducted in 3 steps, that is the preparation of made models with computing Autodesk Inventor Professional 2020, the analysis with generative design, and the printed with 3D printing. This 3D printed product is made in 2 models. Model 1 with a material reduction of 70% topology optimization was better than 50% or 60% material lighting. Model 2, the maximum of 50% Von Mises Stress reduction is smaller than the 60% and 70% reduction.Keywords: Digital prototyping, generative design, topology optimization

Abstract

This research studies the effect of flow rate on the pouring of molten metal into the mould so that the flow rate into the mould can be controlled. Furthermore, this research studies the effect of mould preheating so that the temperature inside the cavity can be maintained, especially for narrow holes. The process starts with making the engine cylinder head pattern and gating system using a three-dimensional printer with polylactic acid resin. The mould pattern and gating system are combined and coated with a layer of cement plaster, silica sand and kaolin. After the coating is dry, the mould is heated until the mould pattern evaporates and there is no residue. The casting process was carried out at pre-heating moulds of 300 0C and 350 0C and a pouring temperature of 800 0C with pouring speeds of 20, 30, and 40 rpm. The final stage of the research is manufacturing test objects and testing mechanical properties. The results showed that the higher the pouring speed, the less perfect the casting results, especially in the cylinder head fins. The best casting results occurred in the pre-heat condition of the 300 0C mould with a pouring speed of 20 rpm, with a Maximum Tensile Strength of 105 N/mm2, Hardness 53 hardness Brinell test (HBN), Density and Porosity of 2.43 gr/cm3. The material used in this study refers to the reference is A356 Aluminum Alloy.

Abstract

Buah Naga dan pisang merupakan komoditas yang dibudidayakan dan dikembangkan di Kecamatan Segedong. Karena buah naga dan pisang merupakan komoditas yang mudah rusak, sehingga kelompok tani mengalami kerugian disebankan banyak hasil panennya yang terbuang karena busuk. Sehingga diperlukan pengetahuan untuk mengolahnya. Kegiatan pengabdian kepada masyarakat (PPM) ini dilaksanakan untuk kelompok tani Desa Parit Bugis dan  Desa  Peniti  Dalam  I  serta masyarakat di sekitas Kecamatan Segedong. Target dan Luaran dari PPM IbM ini adalah: memberikan informasi pengetahuan dan ketrampilan mengenai diversifikasi produk olahan dragon fruit dan banana flour menjadi produk pangan serta membangun jiwa kewirausahaan peserta. Metode Kegiatan yang akan dilaksanakan adalah Pembinaan dan Pembimbingan Ilmu dan Teknologi serta Kewirausahaan. Penjelasan peralatan dan bahan yang digunakan selama produksi, pelatihan dan bimbingan teknis terhadap mitra dalam berproduksi, Pelatihan Kewirausahaan, Pelatihan pembukuan dan strategi pemasaran meliputi: Pengemasan, harga jual, promosi dan distribusi serta evaluasi hasil kegiatan. Hasil quisioner diketahui bahwa 75% peserta belum mengetahui olahan buah naga dan pisang dan 50% tidak mengetahui dan memahami perhitungan usaha, pembukuan sederhana untuk memulai usaha kecil. 100% peserta mengatakan bahwa pelatihan yang diberikan baik mengenai pembuatan produk olahan buah naga dan pisang serta pembukuan dan penentuan nilai jual untuk usaha kecil menarik, berkesan dan produk yang diajarkan/dihasilkan mempunyai nilai jual, 90% peserta tertarik untuk terus membuat sendiri produk yang telah diajarkan walaupun pelatihan sudah selesai dilaksanakan.
