the engine performance is very important at the automotive world, especially on 4-stroke motorcycles, where most people want the engine performance to be better and more economically. In this case to improve engine performance is done by changing the piston on the motor. With a different piston shape can increase the compression ratio. The purpose of this study is to determine changes in compression ratio, torque, power and fuel consumption, after replacing the piston. The test was carried out on a 2006 Honda Tiger, with a standard piston specification with a diameter of 64.5 mm (flat surface) and replaced with a 64.5 mm pro newtech piston (convex surface) by using Pertamax 92 fuel. The results obtained from the comparison of the compression value of 1, 6 : 1, 12.65 ft-lbs of torque, and 2.87 ft-lbs of power so that fuel consumption increases by 5.685%

Overhaul activity is one periodic maintenance by the company to recondition production equipment in order tooperate with high avaibility and realibility. Overhaul activities can also be referred to as project based on a series of work that occirs unique, complex, done in a certain period of time and resources. This factory overhaul project must be completed on time, according to quality and cost as well as zero accident. In connection with the condition of the Covid-19 pandemic, the work is carried out with the Covid-19 health protocol so that ts doesnot become a source of new spread. In this paper will be discussed the implementation of the overhaul of theplant Indarung VI Year 2020 in the pandemic, starting from the stages of planning, preparation, implementation and evaluation (feedback). The realization of work time experienced delays of 2,68 days, quality according to standards and with the realization of a greater cost of Rp. 2.22 Billion. During the overhaul project there were 3 cases of work accidents and there were no additional cases of Covid-19 in the workforce involved in the project.

The comfort factor of a room is determined according to the location, characteristics and activities in the room. In order for the room to feel comfortable, a tool is needed to cool the room. The hall of Campus III UM West Sumatra as a place for academic activities measuring 28.3 m long, 8.3 m wide, 3.2 m high with a capacity of 130 people, requires air conditioning according to the needs of the room. This study aims to determine the need for air conditioning cooling load for the hall space. The research carried out literature review and observation, calculating temperature, temperature, hall size, and others. The result of the research is that the cooling load is 25.44 kW, so 3 units of split PK type AC are needed

The increasing economic growth of the Indonesian people has implications for the number of vehicle ownership, especially cars. However, this increase is not matched by public understanding of the need for maintenance of the engine cooling system. One way that can be done is to use radiator coolant to maintain the cooling system so that engine performance remains in optimal condition. The purpose of this study was to determine and compare the working temperature of the engine when using several types of radiator coolant. This research uses an experimental approach research method. The test was carried out at 750 RPM, 1500 RPM, 3000 RPM and using a coolant containing a mixture of water with ethylene glycol 0%, 30%, 50% and 80%. In the calculation, it is found that the working temperature of the Toyota Avanza 1.5 M/T car engine is very good using a mixture of water and ethylene glycol 50%, namely with an average engine working temperature of 94.8℃, then a mixture of water and ethylene glycol 30%, namely with an average temperature engine working 96.3℃, a mixture of water and ethylene glycol 80%, with an average working temperature of 98.6℃ engine and a mixture of water and ethylene glycol 0%, with an average working temperature of 101.5℃

Carbon Fiber Reinforced Epoxy is a material that is widely used in the manufacture of prosthesis structures. In this research, the carbon fiber used is plain weave-type carbon, while the matrix used is LY5052 epoxy, LY5052 epoxy has advantages such as low viscosity and long pot life making it possible to manufacture large-sized prostheses. The first step in this research is making specimens using the vacuum infusion method and then cutting the specimens with dimensions referring to ASTM D3039. Furthermore, tensile test experiments were carried out with the results obtained that the maximum stress () was 537.15 MPa. As an evaluation, a tensile test simulation was carried out with Finite element analysis using Abaqus software, the material properties used were the results of a tensile test experiment, in the process the mesh selection was carried out by input sizing control many times this was done to determine the accuracy of the results. The tensile test simulation results with abaqus software are 523.3 MPa when compared to the experimental, the difference is only 2.58%. based on experimental and simulation results, the mechanical properties of the Carbon Fiber Reinforced Epoxy LY5052 Composite material are almost the same, so that in the manufacture of prosthesis the mechanical properties data in this study can be used when performing numerical analysis in the prosthesis design process.

Smart key system merupakan salah satu teknologi terbaru yang dimiliki beberapa pabrikan sepeda motor khususnya sepeda motor yang sudah memiliki ECU. Sistem ini memberikan kemudahan bagi konsumen dalam mengoperasikannya karena tidak lagi menggunakan anak kunci atau keyless. Penyematan fitur canggih ini justru dapat meningkatkan rasa aman dan nyaman bagi pengguna. Pada sepeda motor yang masih non ECU tentunya perlu juga diterapkan agar dapat memiliki sistem unggul sebagaimana sepeda motor yang memiliki ECU. Berdasarkan pengamatan yang dilakukan bahwa smart key custom yang dijual di pasaran memiliki 2-3 fitur saja dan itupun masih menggunakan sistem receiver dan transmitter sehingga tidak dapat digunakan untuk jarak jauh. Solusinya adalah mengembangkan sistem smart key yang dapat berfungsi dari jarak yang jauh, khususnya penerapan pada motor non ECU. Tahap awal perancangan adalah mengevaluasi kekurangan pada pengembangan smart key yang sudah ada, dan tahap berikutnya menyusun konsep sistem globalnya meliputi microcontroller, komponen utama dan pendukung serta pemrograman sistem kontrol, sistem monitoring, dan sistem safety. Tahap akhir, merakit dan memasangnya pada sepeda motor serta melakukan serangkaian uji coba guna mengetahui fungsional termasuk ketahanan dari perangkat. Hasil pengujian aplikasi android smart key 3 in 1 dapat berfungsi dengan baik pada kondisi dan jarak berapapun, meskipun pengujian sistem safety ditemukan delay waktu pada range 10,03-13,2 second.

Salah satu perusahaan elektronik rumah tangga yang memproduksi produk berupa AC menerapkan metode kaizen pada proses produksinya. Dari pengamatan dengan metode kaizen, didapatkan bahwa mesin feeder kurang efektif karena umur komponen yang lebih kecil dari yang telah dirancang. pada mesin feeder dengan sistem pneumatik didapatkan jika distribusi beban tidak seimbang dan menyebabkan keausan dini pada piston. Keausan dini menyebabkan peningkatan frekuensi kerusakan dan waktu henti karena pemeliharaan. Untuk mengimplementasikan kaizen, dilakukan modifikasi untuk menciptakan distribusi beban yang lebih seimbang. Modifikasi penyeimbangan lengan robot feeder menghasilkan frekuensi breakdown yang lebih rendah dan meningkatkan usia pakai piston.

Air merupakan kebutuhan utama makhluk hidup setiap harinya. Jumlah produksi air bersih di Indonesia mengalami penurunan dari tahun 2018 sampai 2019. Wibowo (2020) telah membuat mesin produksi air dari udara atmosfer. Mesin ini akan dianalisa dan dimodifikasi untuk meningkatkan volume air yang dihasilkan dari 2 Liter/hari menjadi 4 Liter/hari dan meningkatkan perbedaan temperatur udara yang melalui ruang evaporator. Modifikasi mesin ini dimulai dengan menghitung ulang panjang pipa evaporator dan mendesain ulang ruang evaporator. Mesin ini bekerja dengan mengembunkan uap air menjadi air. Mesin ini menggunakan sistem kompresi uap sebagai sistem pendinginan sepeti mesin terdahulunya. Modifikasi pipa evaporator berbentuk aligned dengan 3 kolom dan 3 baris dengan panjang sebesar 0,756 m tiap pipa. Dengan menggunakan tiga jenis kecepatan udara yang berbeda dalam satu harinya mesin dapat menghasilkan air sebanyak 17,4 Liter; 16,2 Liter; dan 4,8 Liter.
