MODIFIKASI PENAMBAHAN SYSTEM WATER SPARATOR SEBAGAI SOLUSI REDUCE BREAKDOWN PROBLEM FUEL SYSTEM PADA UNIT HEAVY DUMP TRUCK MODEL TL859

---

PT Global Makara Teknik is a private coal mining contractor that uses heavy dump truck model TL859 as a means of transporting overburden (OB). The use of B40 biodiesel fuel (40% biofuel and 60% diesel) in Indonesian mining companies is regulated in a series of government policies, namely Law No. 22 of 2001 concerning oil and gas, presidential regulation no. 191 of 2014, regulation of the Minister of Energy and Mineral Resources no. 4 of 2025 concerning the business and utilization of biofuels. Based on these regulations, mining companies are required to use B40 for unit operations that use diesel engines. The application of B40 biodiesel fuel at PT Global Makara Teknik has not run well for engines with a common rail system, namely the TL859 model unit, the problem that occurs is that the unit experiences low power and black smoke, so that with these problems the consumption of injector use increases, the PA (physical availability) of the unit decreases. This research method uses quantitative and experimental data, the purpose of this study is to maintain the lifetime of the injector by adding a filtration process to the fuel by installing an additional water separator, obtained data by adding a water separator system to get results from the period January - December 2025 MTBF (Mean Time Between Failure) fuel system components have increased from July (40.9 hours), August (61.7 hours), September (110.2 hours) and December (310.8 hours), MTBF (Mean Time Between Failure) injector parts have increased from July (47.5 hours), August (105.8 hours), September (287.8 hours), October (171.7 hours), November (180.7 hours) and December (257.2 hours), from the cost aspect, namely the cost of injector consumption also decreased from October (Rp. 16,705 / month), November (Rp. 5,766 / month) and December (Rp. 4,771/month). The use of B40 biodiesel diesel can be effectively applied in the TL859 heavy dump truck model by adding a water separator to maximize fuel filtration and ensure effective fuel entry into the combustion chamber. Keywords: Common rail, water separator, injector, physical availability, Mean time between failure
