ABSTRAK
Biji Pepaya merupakan limbah yang dihasilkan dari industri rumahan. Umumnya, biji pepaya dijadikan bibit tanaman pepaya. Biji pepaya berpotensi sebagai edible oil. Minyak biji pepaya dapat diperoleh dengan proses ekstraksi menggunakan pelarut n-butil asetat dalam alat sokhlet. Pada penelitian ini digunakan biji pepaya sebagai bahan baku dengan menggunakan pelarut n-butil asetat. Variabel yang diamati adalah waktu ekstraksi dan perbandingan biji pepaya:pelarut. Hasil penelitian menunjukkan komposisi asam lemak minyak biji pepaya tertinggi adalah asam oleat sebesar 63,22% dan diikuti asam palmitat sebesar 17,57%. Bilangan iodin minyak biji pepaya 16,91 mg/gram, Bilangan peroksida minyak biji papaya tidak terdeteksi,
Spesific gravity minyak biji pepaya 0,8939, Kadar asam lemak bebas minyak biji pepaya 5,6410%. kandungan minyak tertinggi diperoleh pada waktu ekstraksi 220 menit dengan perbandingan biji pepaya:pelarut 1:8 sebesar 43%. Dari hasil analisis yang dilakukan pada penelitian ini menunjukkan bahwa minyak biji kurma belum memenuhi standar untuk edible oil.

ABSTRACT
Papaya seed it is a waste product from home industry. Commonly, papaya seed used to be a new plant to grow. Papaya seed have a potential as a edible oil. Soxhlet is used to obtain the oil from papaya seed by using several solvent such as: petroleum ether, methanol and n-hexane. In this research, papaya seed as raw material by using a solvent n-butyl acetate. The variables studied were the time of extraction and the ratio papaya seed to solvent . The results showed that the highest fatty acid com position of papaya seed oil was oleic acid 63,22% and followed by lauric acid 17,57%. Iodine value of date seed oil was 16,91 mg / g. Peroxide value of papaya seed oil not definition. Specific gravity of papaya seed oil was 0,8393. Free fatty acid content of papaya seed oil was 5,6410%. The highest oil content obtained in the extraction time 220 minutes with the ratio papaya seed to solvent = 1 : 8. The oil content was obtained 43%,. From the result at this research showed that papaya seed oil was not fulfilled standard for the edible oil.
