Abstract

UT cabang On Road merupakan salah satu perusahaan yang dipilih oleh operator bus MassRapid Transit (MRT) Jakarta untuk melakukan kontrak perawatan pada unit Scania K310 IB Maxi Busmiliknya, sehingga unit bus siap beroperasi melayani transportasi publik. Pada 2021 unit bus tipe K310mengalami persoalan berupa mesin yang mati mendadak. Pengecekan di lapangan menunjukkan bahwa aliranbahan bakar dari filter bahan bakar ke mesin mengalami sumbatan sehingga alirannya tidak lancar. Daripersoalan yang timbul ini maka dilakukan penyelidikan dan ditemukan aliran bahan bakar yang tidak lancerke mesin. Dari buku referensi yang ada, penggunaan solar B30 yang ada di pasaran Indonesia akanmenyebabkan usia saringan bahan bakar menjadi lebih pendek. Oleh karena itu dilakukan perbaikan padasistem penyaringan (filter) bahan bakar dengan mempercepat penggantian pre fuel filter dari per 20.000 kmpemakaian, menjadi setiap 10.000 km pemakaian. Proses ini dilakukan guna menghindari denda dari operatorbus akibat tidak beroperasi dan terjadinya di jalur khusus bus yang mengakibatkan kemacetan. Metodologipenelitian yang dilakukan adalah mengecek peyebab mogoknya unit, mengambil sampel bahan bakar yangada di filter dan mengirimkan ke lab utuk di analisis kandungannya sehingga dapat diambil tindakan. Prosesperbaikan ini dapat menurunkan kerusakan mesin sampai dengan 0% sehingga target Physical Availability(PA) unit tercapai. Percepatan penggantian saringan bahan bakar ini mengakibatkan jumlah limbah yangdihasilkan dari saringan tersebut juga makin banyak sehingga perlu dibuat juga sistem pengolahan limbahbahan bakar agar dapat dipakai dan tidak dibuang secara percuma.

Abstract

CNC Milling Machine is a machine tool that has a large population but low energy efficiency. The machine tool industry consumes about 10% of the national energy, making it the second largest energy user after transportation sector. To obtain efficient machine performance, the motion in the machining process must be controlled by setting the proper machining parameters. However, there is a contradiction in that CAD/CAM operators and programmers often do not understand the impact of such parameter settings and thus determine parameter values arbitrarily. This study aims to optimize machining parameter settings by providing parameter values proven to have energy-friendly performance. The method used in this research is regression-based response surface methodology. Based on numerical simulations and experiments conducted, variations in feed rate and depth of cut were shown to impact energy consumption significantly. Experiments and tests reduced the energy consumption value below 5A for 78% of the total process.

Abstract

PT AI-ISO workshop on DM Jakarta provides various repair and periodic maintenance services. In periodic maintenance, brake repair jobs have problems replacing the brake pads (brake shoe set) of Isuzu Giga Trucks, which takes about 9 hours. To reduce the processing time, an improvement process is carried out to shorter processing time, so the customer feels more satisfied with repairing his vehicle. From observations, the length of work time was due to the process of changing the brake pads outside the workshop due to the absence of tools to install the brake pads. The repair shop offers to replace a set of brake pads, but the price is higher than just replacing the brake pads, so the customer makes this choice. The improvement made was the manufacture of a rivet installation tool on the brake pads based on the workings of a rivet machine. First, it is necessary to make a brake pad holder so that it does not shift when pressed and ensures that the pressure acting on the rivet is as requested. This tool is also equipped with a Standard Operation Procedure to make it easier for technicians to replace brake pads. The result is a decrease in processing time for the brake pad replacement process from an average of 9 hours to 5 hours. With these tools, repairing the brake system can be accelerated and within the safe limits required in the vehicle's manual, and the customer will be more satisfied.
