Abstract

Spent Bleaching Earth (SBE) merupakan limbah hasil pemucatan minyak yang mengandung 20-40% minyak sehingga perlu dilakukan pemulihan. Tujuan penelitian ini untuk menganalisis pengaruh rasio bahan/pelarut terhadap rendemen dan mutu minyak serta mendapatkan perlakuan terbaik dalam proses ekstraksi minyak dari SBE. SBE yang digunakan berasal dari proses pemucatan crude palm oil (CPO) (bahan A) dan SBE dari proses pemucatan refined bleached deodorized palm oil (RDPO) yang telah disimpan selama tiga bulan (bahan B). Proses ekstraksi menggunakan metode refluks dengan pelarut heksan teknis selama 3 jam. Penelitian ini menggunakan rancangan acak lengkap faktor tunggal dengan perlakuan rasio bahan SBE/pelarut (1:4, 1:6, 1:8) (b/v). Hasil penelitian menunjukkan karakteristik sampel A memiliki kadar minyak 17,17%, kadar abu 31,27%, kadar volatil 33,49%, pH 3,21, dan kadar air 0,72%. Sampel B memiliki kadar minyak 38,28%, kadar abu 48,33%, kadar volatil 47,33%, pH 7,75, dan kadar air 1,00%. Rasio antara bahan sampel A terhadap volume pelarut mempengaruhi rendemen dan densitas minyak, sedangkan rasio antara bahan sampel B terhadap volume pelarut hanya mempengaruhi densitas minyak. Perlakuan terbaik untuk rasio bahan terhadap volume pelarut sampel A adalah 1:8 dengan menghasilkan rendemen minyak tertinggi 88,31%. Minyak yang dihasilkan memiliki bilangan asam 84,44 mg KOH/g, densitas 0,89 g/cm3, viskositas 4,91 cSt, dan bilangan iod 48,07 g iod/100 g. Rasio bahan terhadap volume pelarut terbaik untuk sampel B sebesar 1:8 dengan rendemen minyak tertinggi yaitu 75%. Minyak yang dihasilkan memiliki bilangan asam 2,77 mg KOH/g, densitas 0,87 g/cm3, viskositas 4,36 cSt, dan bilangan iod 40,61 g iod/100 g.

Abstract

Rice is still a strategic commodity in Indonesia, because it is still a staple food for most of Indonesia's population. Fulfillment of production must also be accompanied by aspects of quality fulfillment. This study aimed to evaluate the quality of rice and to evaluate the application of Good Handling Practice (GHP) and Good Manufacturing Practice (GMP) in small and medium rice miling in Karawang Regency. The performance of rice quality was evaluated based on the requirements for the rice quality class from the Minister of Agriculture Regulation Number: 31/Permentan/PP.130/8/2017 which includes water content, head rice, broken grains and whiteness degrees. Based on the results of quality of rice, it was found that the water contents in the medium and premium quality were 64% and 27%, respectively. Based on the criteria for quality of head rice, it was obtained that all samples were not included premium quality and 22.2% in medium quality. For the criteria of broken grains, it was found 36% in medium quality and the other were below the quality standard. Meanwhile, based on the whiteness degree, most of the rice samples were included in the medium and premium rice qualities. The applications of GHP in rice milling were 42% for small rice milling and 50% for medium rice milling, whereas applications of GMP were 69% for small rice milling and 92% for medium rice milling. Lack of socialisation regarding the importance of quality and implementations of GHP and GMP, and cost of risk that must be added by implementing GMP and GHP were factors caused the low quality of rice in Karawang Regency.Keywords: rice quality in Karawang district, GHP, GMP
