Abstract

Tingkat demonstrasi mesin berkaitan dengan daya yang dihasilkan oleh mesin, konsumsi bahan bakar, serta efisiensi dari mesin tersebut. Pemakaian salah satu mesin penggerak awal yaitu motor bakar torak masih sangat dominan, dimana daya yang dihasilkan sampai saat ini masih dirasa unjuk kerja yang cukup baik. Untuk meningkatkan performa sepeda motor, banyak inovasi yang dilakukan dan teknologi yang dikembangkan agar performa motor meningkat sesuai kebutuhan penggunanya. Super KIPS salah satunya, Super KIPS memiliki bagian terpenting berupa klep ( Valve ) yang bisa membuka dan menutup. Selain itu terdapat pula magic ring, merupakan komponen berbentuk ring yang dirancang khusus untuk berbagai jenis sepeda motor dengan memanfaatkan gas aktif lewat knalpot yang terbuang sia-sia. Sebuah nozzle sering berbentuk pipa atau tabung dari berbagai variasi luas penampang, dan dapat digunakan untuk mengarahkan atau memodifikasi aliran fluida (cairan atau gas). Nozzle sering digunakan untuk mengontrol laju aliran, kecepatan, arah, massa, bentuk, dan / atau tekanan dari aliran yang muncul. Kecepatan nozzle dari fluida meningkat sesuai energi tekanannya. Pemasangan magic ring mampu menurunkan nilai KBBS pada putaran kurang dari 9000 RPM, namun ketika putaran mencapai lebih dari 9000 RPM, kondisi standar lebih sedikit KBBS-nya dibanding magic cincin . Begitu pula jika dibandingkan dengan penggunaan variasi nozzle , nozzle dapat menurunkan KBBS lebih sedikit dibandingkan penggunaan magic ring maupun standar .

Abstract

Gasoline motorcycles are a means of transportation that is currently the most in-demand by the people of Indonesia. Most of the youth are waiting for gasoline-fueled motorbikes with superior performance so many lovers from the automotive sector, researchers and industry make modifications to improve the performance of these vehicles. This study aims to improve the performance of the gasoline engine. The research method used is to modify the exhaust manifold on the combustion engine. Modifications are made by adding a Torque Expansion Chamber (TEC) 1 tube 2 channels and variations of nozzles 40, 50, and 60. The next step is to test torque, power, and specific fuel consumption. The results show that the use of 1 tube 2 channel TEC and variations of nozzles 40, 50, and 60 can increase torque, increase power and reduce specific fuel consumption. The highest torque of 9.94 Nm was obtained at 5500 rpm using 1 tube 2 channel TEC and 50 nozzle variations. The highest power of 8.03 HP was obtained at 6250 rpm using 1 tube 2 channel TEC and 50 nozzle variations. Minimum specific fuel consumption with a value of 0.14145 kg/kWh was obtained by using TEC 1 tube 2 channel and nozzle variation 40. Increasing torque by using modified TEC 1 tube 2 channel and nozzle variation 40, 50, and 60 is due to back pressure so that heat that comes out with the exhaust gases is not completely removed by the environment. The increase in power is caused because the power is directly proportional to the torque, while the decrease in specific fuel consumption is caused because the specific fuel consumption is inversely proportional to the power.

Activities are carried out with coordination and discussion with partners. A meeting to determine the capacity of the rotary dryer unit and the needs of electrical energy and heat sources. Whereas for the herbal medicine business entrepreneur group, coordination was carried out to determine the material and motivation management training to foster an entrepreneurial spirit. The rotary dryer unit consists of two main parts, namely: air heater and rotary dryer cylinder. Air heater is made from a range of 3/4 inch diameter mild steel pipes, while the shell wall is made of mild steel plates with 1.2 mm thickness. For air plants centrifugal blowers are used with a 2 inch pipe diameter. A heat source is used by a single burner with LPG fuel. The rotary dryer cylinder, is a concentric tube, from a perforated stainless steel plate used as a place for dried simplicia. While the outer tube is made of mild steel plates. The tube is rotated using a 200 Watt one pasha electric motor. Improved business management with standard management to improve marketing efficiency and development.

Abstract

This study aims to determine the effect of modification of Exhaust Manifold using orifice on engine performance of Suzuki Satria F 150. Experiments were carried out by installing orifice blinds with diameters of 18, 20, 22 mm and circular perforated orifices with diameters of 19, 19.5, 20.5, and 20. mm on the exhaust manifold. Engine performance, torque and power were tested with dyno test. Fuel consumption is measured using a measuring tube. The results showed that using an orifice blind modification, the smaller the exhaust manifold area, the smaller the torque and power produced. The modification uses an orifice hole, the torque and power produced are close to the standard exhaust manifold. Optimal sfc on modifications using orifice blinds is obtained at engine speed of 6000 to 8500 rpm. While at engine speed of 9000 rpm and above, the modification of the exhaust manifold orifice hole is more optimal.

Abstract

Penelitian kali ini menjelaskan tentang proses carburizing pada baja. Perumusan masalah tentang carburizing dengan variasi waktu tahan 15 menit, 30 menit, 45 menit, 60 menit terhadap kekerasan dan struktur mikro pada baja karbon ST60. Proses pack carburizing banyak digunakan untuk meningkatkan kekerasan permukaan pada baja. Pada penelitian ini ukuran butir karbon yang digunakan adalah mesh 140 (105 µm) dengan temperatur 900°C. Hasil penelitian ini menunjukkan bahwa pada variasi waktu tahan 15 menit nilai kekerasan rata-rata 56,7 HRA. Pada waktu tahan 30 menit rata-rata nilai kekerasannya adalah 57,1 HRA. Lalu pada waktu tahan 45 menit rata-rata nilai kekerasannya adalah 57,4 HRA dan pada waktu tahan 60 menit adalah 57,5. Untuk raw material memiliki rata-rata nilai kekerasan 66,7 HRB. Jadi raw material setelah di carburizing mengalami peningkatan kekerasan sebesar 167-173%. Dengan demikian waktu tahan pada proses pack carburizing mempengaruhi kekerasan material

Abstract

Rubber force is a simple but important thing for vehicles. This component is located in the rear wheel drum which is directly connected to the gear. Many factors influence the damage to this component. This research aims to determine how much influence stearic acid has on the hardness and tensile strength values of the lifting rubber compound. The materials used to make the compound are rubber smoked sheet (RSS) and synthetic rubber mixed with the chemicals stearic acid, black carbon white oil, ZnO, paraffin wax, MBTS, comaron resin and sulfur. These ingredients are mixed using two roll mixing until they combine and form a compound sheet. To determine the maturation time of rubber, a rheometer process is carried out. The next process is vulcanization of rubber using a mold that is pressed at a temperature of 1600C and a pressure of 150 psi. Tensile testing uses rubber testing equipment with SNI ISO 37: 2015 (IDT–2011) standards. Hardness testing uses a tool with a Shore A hardness tester scale with ISO 7619–1:2010 standards. Based on the results of the tests carried out, the addition of sulfur has a very significant effect on the hardness value and tensile strength value. For the hardness value of compound 3 with a sulfur composition of 6 phr, it has the highest hardness, namely 77 Shore A and the lowest value is composition 1 with a hardness value of 65.6 Shore A. The highest tensile strength value is 15,394 N/mm2 in composition 1 and the lowest value is in composition 3 with a value of 11.44 N/mm2
