Abstract

Palm Empty Fruit Bunches (TKKS) was the waste which has a fairly high content of lignocelluloses. Meanwhile, TKKS has not been utilize optimally. With a cellulose content of 45%-50%, TKKS then potentially be used as raw material for bioethanol. In the process of production bioethanol, delignification of lignocellulose the first phase was conducted to dissolve ligament between cellulose, hemicellulose and lignin. In this research, delignification process was carried out using NaOH in the ionic liquid system and without ionic liquids. The purpose of this research was to find out the highest content of cellulose which contained in the TKKS and to determine the hydrolysis of delignification results on palm empty fruit bunches and the best hydrolysis conditions was obtained at the hydrolysis process in the choline chloride ionic liquid system. Delignification process were performed using ionic liquids choline chloride (ChCl) in variety of cooking time with amount different ChCl. This research used TKKS powder cooked at a temperature 130 °C with a variety of cooking time 30, 60, and 90 minutes and the variation of ChCl 10%, 15% and 20% weight of TKKS. Delignification research results used ChCl obtained highest content of cellulose was 40,33%, hemicellulose 20,28%, and lignin 3,62% in cooking treatment 90 minutes and 15% ChCl. While delignification without ChCl obtained highest content of cellulose is 24,98%, hemicellulose 8,25%, and lignin 18,99% in cooking treatment 90 minutes. Delignification process using ChCl be able increase the degree of delignification as big as 61,45%. In the hydrolisis process, the main raw material used cellulose of delignification TKKS result, choline chloride, sulfatl acid, and distilled water. The hydrolysis stage in this research was carried out at temperature 105 0C, catalyst (H2SO4) 10% (w / w) cellulose, ChCl 10%, 15%, and 20% (w / w) cellulose and it was stirred at constant speed 120 rpm with reaction time of 30, 60 and 90 minutes. The result in the hydrolysis stage using ionic liquid obtained glucose. LUFF method analysis showed the maximum result of glucose 37.96% with the best conditions in reaction time 90 minutes and the amount of choline chloride 20%.

Abstract

AbstrakPenelitian efek metil ester minyak jarak pagar dan dimetil ester rantai bercabang (DMEB)turunan oleat terhadap emisi gas buang pada mesin diesel. Metil ester minyak jarak pagardibuat dengan cara tranesterifikasi Dari hasil pengujian didapat m minyak jarak pagar dandimetil ester rantai bercabang (DMEB) dibuat dengan proses kabonilasi asam oleat, pengujianini meliputi 4 (empat) jenis bahan bakar yakni B0, B5, B10 dan B10mix yang mengandung metilester berturut-turut 0% (100% solar pertadex), 5%, 10% dan B10 mix (10% metil ester dan 1%DMEB), kemudian dilakukan dengan menggunakan motor diesel TD110-TD115 test bed andinstrumentation for small engines pada putaran 1600 rpm,dan auto gas analizer untukmendeteksi emisi ga buang. Dari data penelitian didapat emisi CO B0 3,42%, B5 1,74%,B101,56%, dan B10mix 1,54%. Dan pada emisi HC untuk B0 185 ppm, B5 185 ppm, B10 184ppm, dan B10mix 175 ppm. Sedangkan emisi CO2 untuk B0 5,96%, B5 5,92%, B10 5,38%, danB10mix 5,26%, sehingga efek metil ester minyak jarak pagar menurunkan emisi gas buangdibandingkan dengan B0 (solar pertadex). Makin tinggi persentase metil ester minyak jaraksemakin turun emisi yang dihasilkan. Penambahan 1% dimetil ester rantai bercabang dapatmenurunkan emisi hidrokarbon (HC) dari 184 ppm menjadi 175 ppm.Kata kunci: Metil ester, Dimetil ester, Tranesterifikasi, emisi, Karbonilasi.

Abstract

Magnesium silicate 75, magnesium silicate 90, and magnesium silicate MgO have been synthesized to increase the concentration of vitamin E from candlenut oil. The reaction of MgO and SiO2 synthesizes the adsorbent magnesium silicate—X H2O by hydrothermal method. The magnesium silicate obtained was characterized by BET, showing the pore size of the three different types of adsorbents, namely magnesium silicate 75 (6.118 nm), magnesium silicate 90 (6.248 nm), and magnesium silicate MgO (3.2238 nm). The adsorbent is used to increase the concentration of vitamin E in candlenut oil. Pecan oil is dissolved with n-hexane in a ratio of 1: 1 in a column containing the adsorbent. After the n-hexane descends from the column tool, vacuum to remove the solvent. Then the results are collected into vials. Then vitamin E levels wer measured by HPLC using standard Tocopherol and tocotrienol. The results of the HPLC test obtained a comparison of the three types of adsorbents' ability to increase levels of vitamin E from candlenut oil, where the adsorbent of magnesium silicate MgO can only increase vitamin E levels which were 429 ppm to 248.72 ppm (0.57 times enriched). In contrast, the magnesium silicate adsorbents 75 and 90 can increase vitamin E levels from 429 ppm to 733.73 ppm (1. 71 times improved) and 855.97 ppm (1.99 times enriched).
