Abstract

Kebutuhan akan energi semakin meningkat seiring dengan kemajuan teknologi dewasa ini, terutama kebutuhan energi listrik yang bersumber dari energi ramah lingkungan. Air garam dapat dijadikan salah satu sumber energi alternatif sebagai media yang digunakan untuk menghasilkan sumber energi listrik tersebut yang relatif murah, mudah didapat dan tidak berbahaya. Air garam yang sering ditemui dalam kehidupan sehari-hari adalah NaCl atau biasa disebut sebagai garam dapur. Dengan membuat sel volta sederhana, dilakukan percobaan untuk mengetahui seberapa besar pengaruh variasi kedalaman celupan dan variasi jarak kedua batang elektroda dalam media elektrolit air garam bereaksi dengan elektroda dalam membangkitkan beda potensial listrik. Percobaan ini menggunakan 2(dua) elektroda berbeda yaitu tembaga(Cu) sebagai katoda dan zink(Zn) sebagai anoda. Elektrolit air garam yang digunakan juga bervariasi kadar garamnya. Dari hasil penelitian ini diharapkan dapat dimanfaatkan oleh masyarakat untuk membantu penyediaan sumber energi listrik alternatif serta dapat mengurangi biaya tagihan langganan listrik setiap bulannya.

Abstract

Ships play an important role in the distribution of goods and passengers. Inside the ship there is a refrigeration machine that is used for food or other accommodation. This research examines the causes of damage to the thermal expansion valve, the emergence of frost on the evaporator pipe and reduced lubricating oil in the compressor cooling machine accommodation space. The research objective of this research is to determine the cause of damage to the thermal expansion valve, the emergence of frost on the evaporator pipe and reduced lubricating oil in the compressor. This type of research is qualitative. From the results of the study it was concluded that the cause of damage to the thermal expansion valve was the blockage of the orifice by dirt and the spring not working on the thermal expansion valve.
