Abstract

ABSTRAK: Proses hidrogenasi minyak sawit dilakukan menggunakan katalis nikel yang setelah proses akan dipisahkan dari produk dengan cara penyaringan. Katalis nikel bekas jarang sekali digunakan berulang karena efektivitasnya menurun. Penelitian ini dilakukan untuk mengkaji penggunaan berulang katalis nikel bekas untuk hidrogenasi minyak sawit dan minyak inti sawit. Penelitian dilakukan dengan 4 tahapan meliputi: 1) penggunaan katalis nikel bekas untuk hidrogenasi (recycle), 2) perolehan kembali nikel dari katalis nikel bekas menggunakan teknik pelindian asam nitrat (recovery), 3) regenerasi nikel ter-recovery melalui impregnasi dan presipitasi menggunakan silika, alumina, dan bleaching earth yang selanjutnya diaktivasi dengan cara reduksi (regeneration), dan 4) pemanfaatan nikel teregenerasi untuk hidrogenasi (reuse). Katalis nikel bekas masih dapat digunakan kembali untuk hidrogenasi namun kadar asam lemak bebas pada produk meningkat. Recovery nikel sebesar 99,6% dari katalis nikel bekas dapat diperoleh menggunakan asam nitrat dengan konsentrasi 1,8 M, rasio katalis nikel bekas dan asam nitrat pada nisbah 1:14, suhu pada 80 °C dan waktu reaksi selama 4,8 jam. Katalis nikel terimpregnasi dan terpresipitasi dapat digunakan untuk menghidrogenasi minyak sawit.

Abstract

Salah satu tahap yang penting dalam perancangan pabrik adalah perhitungan keekonomian yang biasanya dilakukan dengan menggunakan aplikasi simulasi proses. Beberapa penelitian terdahulu, memanfaatkan SuperPro Designer sebagai simulasi proses, dan belum banyak yang menggunakannya pada proses produksi bioetanol khususnya yang berbahan baku tandan kosong kelapa sawit (TKKS). Pada simulasi ini, dilakukan empat skenario proses: (1) SHF-Adsorpsi; (2) SHF-Permeasi Uap; (3) SSF-Adsorpsi;  dan   SSF-Permeasi Uap, dimodelkan menggunakan SuperPro Designer yang memfasilitasi komposisi bahan baku dan produk, ukuran unit operasi, konsumsi utilitas, estimasi modal dan biaya operasional serta pendapatan dari produk dan co-product. Permodelan didasarkan pada data yang diperoleh dari produsen etanol, penyedia jasa teknologi, manufaktur peralatan dan jasa engineering untuk industri. Dari hasil analisis ekonomi hasil simulasi, skenario SSF-Permeasi Uap yang paling rendah biaya produksinya dan dapat dikembangkan di Indonesia dengan Payback period 4,07 tahun; ROI 24,55%; dan IRR 18,98%. Konversi bioetanol standar bahan bakar yang dihasilkan pada skenario SSF-Permeasi Uap adalah 29,58%. Berdasarkan analisis sensitivitas pada skenario tersebut, fluktuasi harga jual bioetanol, harga tepung TKKS dan harga enzim sangat mempengaruhi nilai keekonomian pabrik bioetanol.

Abstract

A flavor is a substance which may be a single chemical entity, or a blend of chemicals of natural or synthetic origin whose primary purpose is to provide all or part of the particular flavor effect to any food or other product take in the mouth. A vast array of compounds may be responsible for the aroma of the food products, such as alcohols,aldehydes, eesters,dicarbonyls, short to medium-chain free fatty acids, methyls ketones, lactones, phenolic compounds.At present, due to the high cost or lack of availability of natural flavor extracts, most commercial flavorants are chemically synthesized, mostly from petroleum-derived precursors. Because chemical synthesis often uses environmentally unfreiendly production processes, it is desirable to switch to bioproduction, including the extraction from natural source, de novo microbial process (fermentation ), and bioconversion of natural precursos using micro-organisms or isolated enzymes.Natural flavour compounds usually exist at very low concentratiuons. To recover the flavour compounds at a purity of interest for practicial applications , flash distillation and adsorption are being used degradation as wellas high energy cosumption. These challenges inspire and encourage the development of a safer and more economical separation technique, such as: pervaporation techniques, head-space techniques, and supercritical fluid extraction.The scope of this paper covers the development in the bioflavor production, sources, isolation and recovery techniques.This paper is aimed at providing the information related on natural flavor issue which can be used as an additional information to the researcher on the natural falvor industry.

Abstract

 A study on the effect of oleoresin on rice quality during storage has been coducted. Four treatment were done i.e. spraying using pepper oleoresin of 200, 250, 300 ppm and control. Each treatment used 5 kgs rice packed in gunny sacks. Spraying were done on the sacks. Observation on the amounth of rice weevil, texture, taste, flavor and colour, was done every two months. The result showed that up to four months storage, the amounth of weevil in rice sprayed with 250 ppm oleoresin decreased by 70.74% as compared to control, and have the most preffered texture and colour, more preffered flavor as compared to control and no significantly different taste as compared to other treatments. Up to six months storage, the same treatment decreased the amounth of weevil by 49.76%, while those with higher concentration (300 ppm) decreased the weevil by 66.08% but the texture, taste and colour were not significantly different as compared to other treatments.

Abstract

Pandanus conoideus (buah merah or tawi) is exclusively grown in Papua island and its neighbor areas, and indigenous people have been consuming it as functional food for thousand years. We have reported safety and anti-tumor effects of Buah Merah extract oil (S.B.M) in experimental animals. However, mutagenicity or genotoxicity of S.B.M has not been evaluated. We carried out mutagenetic evaluation of S.B.M by in vitro Ames test using salmonella typhimurium  TA98, TA100, TA1535 and TA1537 and escherichia coli WR2uvrA with or withou the activation of S9 mixture. Concentrations used for this test were 313-500ug/plate. The results show that there is no increase in revertant colonies, suggesting that S.B.M has no mutagenic activities under the conditions of this study.
