Abstract

ABSTRACT Heat Exchanger is equipment used to carry out the process of exchanging heat between two fluids, either liquid (hot or cold) or gas, where these fluids have different temperatures. Singkarak hydropower plant also uses a plate type heat exchanger with the code M10-BFG in operation. Serves to exchange heat in the oil used in the upper oil pot, which functions as a cooler and lubricant for the upper bearing and thrust bearing. Seeing the function of the upper and thrust bearings, which are two important bearings in the unit. A good maintenance process is needed on the plate heat exchanger to maintain the condition of the oil at working temperature, which is at 45-55 0C. Through this research, the authors analyzed the performance of the M10-BFG plate heat exchanger with the parameters of the actual heat transfer coefficient and monthly temperature trends. After doing research with quantitative methods through data collection and data processing, it was found that unit 4 has the highest actual heat transfer coefficient of 875.666-900.574 W, but has the shortest usage time, for 42 days based on the existing trending temperature. This is because in unit 4 the oil flow (870-900 l/minute) is below standard, and the size of the heat exchanger plate (55 cm) has shrunk far from the initial value (63 cm). So it is necessary to carry out corrective maintenance on unit 4. Meanwhile, the lowest actual heat transfer coefficient is found in unit 1 with a value of 706.797-770.027 W and the longest plate heat exchanger usage time is in unit 3, with an estimated 121 days before reaching the 55 0C alarm.

Abstract

Alat uji puntir adalah suatu alat yang dirancang untuk mengukur seberapa besar gaya puntir yang dapat dilakukan saat melakukan pengujian dari suatu alat. Alat puntir terbagi dua macam, otomatis dan manual. Saat ini alat uji puntir manual masih ada yang menggunakan tenaga manusia untuk menjalankannya dengan cara memutar hendel dan juga masih manual dalam membaca jumlah putaran spesimen dan waktu puntiran. Dalam skripsi dilakukan pengujian alat uji puntir menggunakan motor daya 1 Hp dan putaran 1400 rpm, jumlah putaran spesimen menggunakan sistem elektronika (sensor). Tujuan pengujian alat uji puntir ini mengetahui hasil parameter pengujian. Proses pengujian alat puntir ini adalah : proses memasukkan kawat ke kepala puntir dan kepala tetap, proses menghidupkan tachometer, dan proses hidupkan mesin. Dari hasil pengujian alat uji puntir diperoleh parameter pengujian yaitu: Nilai torsi terbesar 84,04 Nm, Gaya terbesar 16.700 N, Momen puntir terbesar 42,01 N.m, Tegangan terbesar 878.947 N/m2, Regangan paling panjang 0,018 mm, Modulus elastisitas terbesar 29 ×.10-7 N/m2, Tegangan puntir terbesar 14.200 N/m2.

Abstract

This study aims to analyze the causes of overheating in Pertamax fuel pumps at PT. Pertamina Patra Niaga–Fuel Terminal Medan Group and determine the appropriate maintenance actions to prevent operational failures. Overheating in pumps can cause serious damage and operational disruptions that have the potential to disrupt fuel distribution. The methodology used includes collecting operational data, analyzing pump conditions using infrared thermography, and evaluating pump performance based on industry standards. The results of the study indicate that overheating is caused by several factors such as component wear, inadequate lubrication, and fluid flow instability. Based on these findings, several preventive and predictive maintenance actions are recommended, including maintenance rescheduling, improving the lubrication system, and implementing real-time temperature monitoring. The implementation of these maintenance actions is expected to improve pump reliability and reduce the risk of overheating in the future.
