Abstract

Limbah kelapa sawit merupakan bagian tersisa dari hasil tanaman kelapa sawit yang bukan tergolong ke dalam produk utama ataupun hasil dari bagian proses pengolahan kelapa sawit. Setiap tahunnya produksi kelapa sawit semakin meningkat yang mengakibatkan kemungkinan juga terjadi peningkatan pada limbah kelapa sawit. Pemanfaatan limbah tanda kosong kelapa sawit (TKKS) mencapai 22-23% saat ini. Salah satu cara untuk memanfaatkan TKKS adalah dengan mengekstraksi selulosa sebagai bahan baku fabrikasi bioplastik yang ramah lingkungan. Hal ini mampu mengurangi permasalahan lingkungan yang ditimbulkan oleh limbah kelapa sawit dan limbah plastik yang sulit terurai. Penelitian ini bertujuan untuk mengetahui kandungan selulosa yang ada pada TKKS yang berpotensi sebagai bahan baku fabrikasi bioplastik. Selulosa yang diekstraksi melalui proses delignifikasi NaOH 12% mendapatkan perolehan selulosa rata-rata 44,70% terhadap TKKS dan berwarna hitam. Untuk memastikan kandungan selulosa maka dilakukan pengujian metode SNI dan diperoleh hasil rata-rata 90,33% dan berwarna krem. Untuk menghilangkan sisa pigmen dilakukan bleaching dan diperoleh persen rendemen rata-rata 71% dengan warna krem cerah. Perolehan selulosa di pengaruhi oleh konsentrasi larutan, waktu dan suhu. Dengan persen perolehan selulosa yang tinggi pada ekstraksi TKKS maka dapat diolah menjadi bahan baku bioplastik yang lebih ramah lingkungan sehingga dapat dimanfaatkan sebagai pengganti plastik.

Abstract

Reception Oil Tank (ROT) is a unit at a clarification station that has a function as a temporary storage tank for filtered crude oil from the vibro-separator unit and also to retain heat. In this ROT, the heat provided comes from direct injection of hot steam and steam coils with temperatures ranging from 90-95 0C. This research was conducted with the aim of determining the flow rate of materials into and out of ROT using the principle of mass balance and determining the levels of each component in the oil in ROT before further processing. Based on the results of the mass balance calculation, it was obtained that the flow rate of crude oil entering ROT was 10794.2 kg/hour. The composition content of the materials entering ROT in 10 mL includes 37.6% oil, 26.6% water and 35.8% non-oil solid while the composition levels of materials leaving ROT to CST include 41.6% oil, 27% water, and non-oil solids 31.4%. The oil content has increased during the process that occurs in the ROT at the clarification station.

Abstract

Red Palm Oil (RPO) is the result of refining Crude Palm Oil (CPO). In further processing to obtain cooking oil, several processes are undergone to produce a clear oil, which is very different from its original product, CPO. RPO is rich in beta-carotene and its refining process does not include bleaching. The production of RPO utilizes the acid degumming method with different acid variations, namely phosphoric and sulfuric acid, with varying concentrations of 0.05% and 0.075%. The results showed that the average percentage of RPO produced reaches 44.05%. Furthermore, the quality analysis of RPO also meets the SNI-3741-1995 standards (quality standard of cooking oil), with the average of free fatty acid value of 1.41% (max 3%), peroxide value of 1.04 mg oxygen/100 g (max 1.6 mg oxygen/100 g), and moisture value of 0.04% (max 0.3%).
