Abstract

Biodiesel merupakan alternatif terbaik pengganti bahan bakar diesel yang bersumber dari fosil. Selain dapat digunakan secara langsung pada mesin tanpa modifikasi, biodiesel juga ramah lingkungan. Pengembangan biodiesel kedepan lebih diarahkan ke bahan nonpangan. Salah satu bahan nonpangan yang berpotensi sebagai bahan biodiesel adalah kemiri sunan [Reutealis trisperma (Blanco) Airy Shaw]. Proses produksi biodiesel minyak kemiri sunan saat ini masih menghasilkan biodiesel yang belum memenuhi Standar Nasional Indonesia (SNI). Penelitian ini dilakukan di Lembaga Minyak dan Gas serta di Balai Penelitian Tanaman Industri dan Penyegar bulan November 2011, bertujuan mengevaluasi karakteristik biodiesel kemiri sunan dan membandingkannya dengan SNI (SNI-04-7182-2006) dan standar USA (ASTM D6751). Metode pembuatan biodiesel menggunakan proses transesterifikasi dua tahap. Hasil yang diperoleh menunjukkan bahwa rendemen biodiesel kemiri sunan mencapai 88% dari volume minyak. Dari 18 kriteria yang diamati, hanya residu karbon yang belum memenui kriteria SNI. Sedangkan untuk standar USA, yang belum memenuhi kriteria adalah residu karbon dan titik nyala.  The Characteristic Of The Philippine Tung [Reutealis Trisperma(Blanco) Airy Shaw] Biodiesel Processed Through Two Step Transesterification ProcessABSTRACT Biodiesel is likely to be the best alternative to replace diesel derived fuel from fossil. It may be used directly onto machines without any necessary modification and be environmental friendly. Biodiesel development in the future will focus on non-edible vegetable oils of many potential sources. Philippine tung [Reutealis trisperma (Blanco) Airy Shaw] might be considered. However, biodiesel production at present has not been standarized by  Indonesian National Standard (SNI). A study was conducted at the Research and Development Center for Oil and Gas Technology and Indonesian Research Institute for Industrial and Beverages Crops on November 2011. The objective of this study was to evaluate the characteristics of Philippine Tung biodiesel and compared with SNI (SNI-04-7182-2006) and USA standart (ASTM D6751). The method used was a two-stage transesterification process. The result showed that the ratio of biodiesel to total oil volume (v/v) was 88%. From 18 parameters on SNI based there was only carbon residue which is not meet SNI. While based on US standard, flash point and carbon residue didn’t meet with the criteria.

Abstract

Sebagian besar petani karet di Indonesia membuat bokar masih menggunakan koagulan yang dapat merusak mutu karet seperti pupukTSP, tawas, dan sejenisnya. Koagulan tersebut bersifat asam tetapi tidak mempunyai sifat antibakteri dan antioksidan sehingga bokaryang dihasilkan bermutu rendah dan berbau busuk. Penelitian dilaksanakan di perkebunan karet rakyat di Jawa Barat dari bulan Meisampai November 2012. Tujuan penelitian adalah mengetahui pengaruh konsentrasi asap cair kayu karet dan tempurung kelapaterhadap pengurangan polusi udara pada lump. Rancangan yang digunakan adalah acak kelompok, dengan delapan perlakuan, diulangempat kali. Parameter yang dianalisis pada asap cair meliputi pH, kandungan total phenol, kandungan total asam, dan komponensenyawa penyusun asap cair. Pada lump yang diamati adalah pH penggumpalan, uji organoleptik bau, kandungan NH3 dan kadar karetkering (KKK). Hasil penelitian menunjukkan asap cair kayu karet mempunyai kandungan total asam yang lebih tinggi daripada asapcair tempurung kelapa, tetapi mempunyai kandungan senyawa phenol yang lebih rendah daripada asap cair tempurung kelapa. Sebagaikoagulan, asap cair kayu karet 15% dan asap cair tempurung kelapa 10% menghasilkan mutu lump yang baik dengan gumpalansempurna tidak berbau busuk dan mempunyai KKK kategori mutu 1, yang memenuhi spesifikasi persyaratan mutu SNI 06-2047-2002. Kualitas lump yang dihasilkan lebih baik daripada penggunaan asam format (koagulan rekomendasi), terutama dalam menanganipolusi udara pada lump. Dengan demikian, asap cair kayu karet maupun asap cair tempurung kelapa merupakan koagulan ramahlingkungan.Kata Kunci: Kayu karet, tempurung kelapa, asap cair, lump, ramah lingkunganMost of rubber farmers in Indonesia make lumps on which some coagulants such as TSP fertilizer, alum and others are often used. These coagulant areacidic but they do not have antibacterial and antioxidant properties. As a result, the lumps yielded or produced were low in grade and foul smelling. Astudy was carried out in smallholder rubber plantations in West Java Province from May to November 2012. The purpose of this study was todetermine the effects of the concentration of rubber wood liquid smoke and coconut shells liquid smoke to reduce air pollution on the lumps. The designused a randomized block with eight treatments and four replicates. The parameters analyzed of the liquid smokes include pH, total phenol content,total acid content, and the components of compounds contained in the liquid smokes, while those of the lumps include pH clotting, odor organoleptictest, NH3 content and dry rubber content (DRC). The results showed that the rubber wood liquid smoke has a total acid content higher than thecoconut shell liquid smoke, but its phenol content is lower than that of coconut shell liquid smoke. As coagulants, the rubber wood liquid smoke of15% and coconut shell liquid smoke of 10% produce a good quality of lumps with perfect clots, does not produce bad smell and has DRC categoryquality 1. It meets the specifications of SNI 06-2047-2002 quality requirements. The use of rubber wood liquid smoke and coconut shell liquidsmoke in lump processing yields better quality than that of formic acid (coagulant recommended), especially in reducing of air pollution of lumps.Thus, rubber wood liquid smoke and coconut shell liquid smoke uses is environmentally friendly coagulant.

Abstract

In this paper, the catalysts (Nano-HZSM-5 and Fe-La/nano HZSM-5) were prepared with incipient wetness impregnation and applied for hydrocracking of Sunan candlenut oil. The hydrocracking process was conducted in a batch reactor with a pressure of 20-30 bar H2 gas for 2 h under various temperatures. The results demonstrated that hydrocracking of Sunan candlenut oil using nano HZSM-5 and Fe-La/NHZ catalysts could be converted into aromatic hydrocarbons, and the reaction temperature affected hydrocarbon production. The aromatic compounds, such as propyl-benzene, 1-ethyl-3-methylbenzene, heptyl-benzene, 2-ethyl-naphthalene, etc., reached 35.51% over the Fe-La/NHZ_2 catalyst. In all cases, the zeolite-based catalysts are the most suitable to produce aromatic hydrocarbons. Metal impregnated (Fe and La) on nano HZSM-5 catalyst could improve the aromatics compounds due to increased metal and acid sites. Copyright © 2024 by Authors, Published by BCREC Publishing Group.

Abstract

Improving the quality of cocoa beans poses a great challenge when dealing with raw unfermented beans, as this process requires a relatively longer time. Furthermore, the roasting process, which is crucial in flavor development, can reduce the polyphenol content and antioxidant activity of cocoa beans. This study aimed to analyze the effects of different cocoa bean fermentation and puffing gun roasting methods on physicochemical characteristics of cocoa nibs. This research was carried out with two types of treatment: variations in puffing pressure (3, 4, and 5 Bar) and type of coco beans as raw material (unfermented, spontaneously fermented, and fermented using ragi tape). The results showed that carbohydrate content increased with increasing pressure of puffing gun; but otherwise, increasing puffing pressure decreased water content, fat content, total polyphenols, antioxidant activity, and hedonic scores for taste and aroma. The type of raw material treatment significantly influenced ash content, carbohydrates, L* (lightness) and a* (redness) color intensity, fat content, antioxidant activity, taste, and aroma. Cocoa nibs fermented spontaneously and roasted at a pressure of 3 Bar had the highest fat content, antioxidant activity, and the most favorable sensory scores for taste and aroma. The results of this study provide important insight for developing cocoa bean processing techniques that preserve desirable physicochemical properties and improve consumer preference.
