Abstract

Mesin stirling adalah sebuah mesin kalor atau panas pada siklus yang tertutup dirancang untuk dapat mengubah energi panas yang dihasilkan menjadi energi mekanik menjadi energi listrik. mesin stirling akan bekerja akibat adanya perbedaan suhu yaitu panas dan dingin. Perbedaan suhu yang terjadi akan mengakibatkan perbedaan tekanan dimana ketika tekanan semakin besar maka akan dapat menggerakkan piston. Piston yang telah dihubungkan pada poros engkol kemudian bergerak secara terus menerus sehingga dapat menggerakkan roda. tujuan penelitian ini yaitu untuk mengetahui daya output mesin stirling dengan variasi beban lampu dan untuk mengetahui temperatur kerja yang ideal pada daya output maksimum. Metode yang digunakan pada penelitian ini taitu metode eksperimental skala laboratorium. Berdasarkan hasil penelitian mesin stirling dapat disimpulkan bahwa data putaran tanpa beban mesin stirling sebesar 2636 rpm dengan temperatur sebesar 45 oC, dan data dengan diberi beban dinamo sebesar 1097 rpm, tegangan 12 Volt, dan arus sebesar 66 mA. Sedangkan diberi 5 beban lampu menghasilkan daya sebesar 0,80 Watt. Daya output maksimum sebesar 0,80 Watt pada temperatur kerja mesin stirling 40 oC. Kata kunci : Unjuk kerja, mesin stirling dan beban lampu.

Abstract

This research aims to analyze the performance of the pump P-8340A operated by an electric motor and a diesel motor in the tank T-8320A/B. Apart from focusing on the performance of the two types of motors as pump drivers, this study also evaluates the time to fill the fire fightine water tank and the factors that influence the operational efficiency of the pump.The research methods used include taking field data at the operating location, analyzing flow capacity, pressure head and speed head, as well as calculating pump power and efficiency. The analysis results show that pumps with electric motors have a longer charging time compared to diesel motors, namely 38 hours for electric motors and 29 hours for diesel motors, with flow capacities of 239.68 m³/h and 310.54 m³/h respectively.From this research it was also identified that the total head losses in the pump were influenced by friction factors in the piping system and the characteristics of the fluid being transferred. The conclusion of this research is that although electric motors are more efficient in energy consumption, diesel motors are still superior in capacity and speed in operating the P-8340A pump. Recommendations for future operations include closer monitoring of the piping system and considering modifications to the drive system according to operational needs.
