PENGARUH VARIASI SUHU DAN WAKTU KONVERSI BIODIESEL DARI MINYAK JARAK TERHADAP KUANTITAS BIODIESEL YANG DIHASILKAN

Riman Sipahutar, Harry Lukman Lumban Tobing

Abstract


ABSTRAK

Biodiesel merupakan bahan bahar substitusi solar dewasa ini. Salah satu minyak nabati yang memiliki banyak keunggulan untuk dikonversi menjadi biodiesel adalah minyak jarak pagar. Proses produksi biodiesel dari minyak jarak dipengaruhi beberapa faktor diantaranya konsentrasi metanol, konsentrasi katalis, pengaruh suhu, dan pengaruh waktu reaksi. Penelitian ini dilakukan untuk mengetahui pengaruh suhu dan waktu reaksi dalam reaktor biodiesel. Penelitian menggunakan metode rancangan acak dengan variasi suhu 300C, 450C, 600C dan variasi waktu 30 menit, 60 menit, 90 menit, 120 menit. Hasil penelitian menunjukkan  variasi suhu memberikan pengaruh berbeda sangat nyata terhadap kuantitas biodiesel sedangkan variasi waktu memberikan pengaruh berbeda tidak nyata terhadap kuantitas biodiesel yang dihasilkan. Suhu terbaik  pada penelitian adalah 60 0C dan waktu terbaik selama 120 menit.

Kata kunci: Biodiesel, Minyak Jatropha, Suhu, Panas, Reaktor.

ABSTRACT

Biodiesel is a substitute fuel of diesel fuel nowadays. One of plant oils that has many advantage converted to biodiesel is Jatropha Oil. The process of biodiesel production from Jatropha Oil was affected by several factors including consentrate of methanol, consentrate of catalyst, temperature effect, and time reaction effect. This research was conducted to determine the effect of temperature and time reaction in biodiesel reactor. The research using method of randomized design with  variation temperature 300C, 450C, 600C and variation time 30 minutes, 60 minutes, 90 minutes, 120 minutes. The result showed that variation temperature give very real different effect on the quantity of biodiesel while variation time give not much real different effect on the quantity of biodiesel produced. The best temperature in research was 600C and best time was 120 minutes.

Keywords : Biodiesel, Jatropha Oil, Temperature, Heat, Reactor.
