Abstract

An EFI cars (Electronic Fuel Injection) is not equipped with a pressure fuel pump indicator, so the driver does not know the the fuel pump performance. If the fuel pump work under the standard, the engine is not responsive to acceleration, engine temperature can be increased and the performance of the engine is lowered. This research are trying to design a fuel pump pressure detector using a pressure sensor. The research methodology used is the Research and Development (R & D) consisting of product design, design validation, design revisions, and test products. This study used three product design because the design of the first and the second has not been as expected. The third design uses a comparator circuit as the controller three indicator LED (Light Emitting Diode). If the fuel pump working pressure of 2,1kg / cm²-2.5 kg / cm², the three colored LED green, yellow and red lights up. If the fuel pump working pressure of 1.6 kg / cm²-2,0kg / cm², the two LED will light up the colors yellow and red. If the fuel pump working pressure of 1,0kg / cm²-1.5 kg / cm², it is only one red LED are illuminated. A comparison between the changes in pressure to produce the output voltage linear data and repeatibility = 0.

Abstract

A city car is needed to overcome congestion and parking spaces in urban areas. However, currently, the body design of the city car is still experiencing problems, namely the value of the large drag coefficient, which causes an increase in fuel consumption. This study aims to design a city car body with two passengers that is more aerodynamic so as to minimize fuel use. This research method is a numerical simulation model using the ANSYS fluent students version 2021. Parameters in the form of drag coefficient values, velocity streamlines and velocity contours on the city car are aerodynamic aspects that are analyzed. The results show that the dimensions of the designed city car have a length of 2.59 m, a width of 1.6 m, and a height of 1.52 m by considering the ergonomic parameters and comfort of the user so that it fits the character of the people in Indonesia. In addition, from the independence grid analysis performed, the value of the number of meshes that have the smallest error value is obtained, namely mesh C (the number of meshes is 129,635). Mesh C has an error of 7.2%. It was found that as the velocity increases, the value of the drag coefficient (CD) produced is relatively smaller. In a city car with a velocity of 10 m/s, the drag coefficient value is 0.599, at a velocity of 20 m/s, the drag coefficient value is 0.594, and a velocity of 30 m/s is a drag coefficient value of 0.591.

Abstract

Tujuan pelakasanaan kegiatan pengabdian kepada masyarakat ini untuk menghasilkan inovasi alat pengering udara yang dapat dimanfaatkan dalam pengecatan bodi mobil, selain itu meningkatkan pengetahuan mitra UMKM pengecatan bodi mobil. Meningkatnya kebutuhan manusia terhadap teknologi terutama kendaraan menjadikan banyaknya kendaraan yang bermunculan waktu demi waktu. Perkembangan ini menjadi peluang usaha yang sangat besar. Pengecatan mobil merupakan salah satu peluang usaha di dunia kendaraan yang cukup menguntungkan mengingat tingkat pertambahan mobil yang semakin pesat. Masyarakat yang kerap kali melakukan pengecatan mobil biasanya dikarenakan terjadi kecelakaan sehingga menimbulkan kerusakan pada bodi mobil atau hanya karena ingin memperbarui warna mobil agar sesuai dengan keinginan. Salah satu usaha repair body mobil di Nagari Tanjung Alam Bukittinggi adalah Total Auto Mobil, permasalah yang terjadi adalah di dalam kompresor terdapat uap air dikarenakan masih menggunakan kompresor biasa. Hal ini bisa menimbulkan bercak pada hasil pengecatan disebabkan efek dari uap air pada udara saat proses pengecatan. Berdasarkan masalah ini tim pengabdi mencoba membuat inovasi pembaruan pada alat pendukung kompresor. Melalui kegiatan ini pemberdayaan dan perekonomian masyarakat penggerak UMKM menjadi lebih meningkat khususnya bengkel Total Auto Mobil, serta masyarakatpun mendapat pengetahuan baru yang sangat bermanfaat.

Abstract

Penggunaan Elektroliser secara umum dapat menurunkan tingkat konsumsi bahan bakar pada mobil Toyota Kijang 5 K. Menurunnya konsumsi bahan bakar pada mobil tersebut melalui penggunaan elektroliser dikarenakan elektroliser dapat menghasilkan gas hidrogen (H2) dan Oksigen (O2) dari hasil pemisahan molekul air yang terdiri dari oksigen dan hidrogen sebagai pembentuknya. Hidrogen yang telah dipisahkan dari oksigen tersebut jika disalurkan ke dalam air filter dan masuk ke ruang bakar, dapat menyempurnakan proses pembakaran pada mesin.

Abstract

Penelitian ini membahas tentang coeffisient of performance atau COP pada trainer pengkondisian udara yang mengunakan motor listrik sebagai pengerak utama dari trainer ini yang mengantikan mesin konvesional yang umumnya dipakai pada sistem pengkondisian udara. Coeffisient of performance atau COP adalah salah satu indikator yang menentukan kerja dari sistem itu sendiri. Jenis penelitian yang digunakan adalah metode eksperimen dimana besarnya nilai Coeffisient of performance (COP) dilihat. Dari trainer pada putaran 2970 RPM. Setelah mendapatkan data pada trainer maka dilakukan perhitungan untuk mencari besarnya nilai kerja kompresor, nilai kalor yang dilepas kondensor, nilai kalor yang diserap evaporator, nilai COP aktual, nilai COP ideal, nilai efisiensi dan nilai laju aliran massa pada trainer, dengan nilai COP terendah yaitu sebesar 2,17 dan terbesar yaitu 2,24.  This study discusses the coefficient of performance or COP in air conditioning trainers that use electric motors as the prime mover of this trainer replacing conventional engines which are generally used in air conditioning systems. The coefficient of performance or COP is one of the indicators that determines the work of the system itself. The type of research used is an experimental method which looks at the Coefficient of performance (COP) value of the trainer with a rotation of 2970 RPM. After obtaining the data from the trainer, calculations are performed to find the working value of the compressor, the calorific value released by the condenser, the calorific value absorbed by the evaporator, the actual COP value, the ideal COP value, the efficiency value and the mass flow rate value at the trainer, with the highest COP value, namely of 2.17 and the largest of 2.24.
