Coco ethanolamide obtained from the amidation of Fatty acid methyl ester (FAME) from coconut oil with monoethanolamine using zirconium (IV) chloride and tert-amyl alcohol was observed in this study. Several effective parameters were evaluated in term of catalyst concentration (5-9% w/wFAME), reaction temperature (80-100oC) and stirring speed (200-400 rpm). Response Surface Methodology (RSM) was used to optimize and to observe the interaction effects of the three variables on the FAME conversion. The capability of the process was measured from the number of FAME converted to coco ethanolamide. In the range of parameters evaluated, the conversion increase by increasing the catalyst concentration up to 9% (w/wFAME), but decreases after the optimum value. At the optimal condition, the model predicts a maximum FAME conversion of 86.27%, mainly due to a strong interaction between catalyst concentration and stirring speed.

ABSTRAKTanaman orok-orok atau Crotalaria juncea L adalah tanaman leguminosa yang termasuk ke dalam keluarga perdu dan semak  Biji orok-orok mengandung  12,6 % minyak dengan 46,8 % asam linoleat, 4,6 % asam linolenat, 28,3 % asam oleat dan 20,3% asam jenuh. Metode yang digunakan adalah metode ekstraksi padat-cair dengan pelarut etanol. Pada penelitian ini dioptimasi menggunakan RSM (Response Surface Methodology). Bahan baku yang digunakan adalah biji orok-orok dan etanol. Biji orok-orok dihaluskan menggunakan blender, kemudian dimasukkan dalam labu leher tiga untuk proses ekstraksi menggunakan pelarut etanol. Ekstraksi dilakukan dengan memvariasikan berat sampel, suhu ekstraksi dan waktu ekstraksi. Dengan variasi berat sampel (70, 80,90 gram),  Suhu (55, 65 dan 75oC), Waktu (3,4 dan 5 jam). Setelah selesai ekstraksi larutan di saring menggunakan kertas saring. Selanjutnya dilakukan pemisahan antara minyak dan pelarut dengan proses destilasi. Pengujian yang dilakukan adalah uji densitas, yield, kadar FFA dan uji komposisi dengan alat GC-MS. Densitas terendah dihasilkan pada Suhu 75oC, berat sampel 70 dan waktu ekstraksi 4 jam sebesar 0,788 g/ml. Yield tertinggi dihasilkan pada suhu 65oC, berat sampel 90 gr dan waktu ekstraksi 3 jam sebesar 19,943 %. Kadar FFA terendah dihasilkan pada suhu 65oC , berat sampel 90 dan waktu 5 jam. RSM memberikan hasil optimasi terbaik pada suhu 75oC, berat sampel 89,64 gram dan waktu ekstraksu 3 jam dengan yield 19,943, densitas 0,89 gr/ml dan kadar FFA 1,2674 %. Dari hasil uji GC-MS diketahui bahwa minyak biji orok-orok mengandung methyl ester of undecanoic acid, 2-methylpentanoic acid, myristic acid methyl ester, methyl linolelaidate, 2-cyclopentylacetohydrazide dan 2-methylpentanoic acid.Kata Kunci : biji orok-orok, ekstraksi, densitas, yield, kadar FFA

Research on the manufacture of methyl esters from avocado seeds (Parsea americana Mill) with eugenol-based catalysts has been conducted. The aim is to determine the catalyst concentration used to produce methyl esters with the highest rendement and determine the composition of fatty acid methyl ester in avocado seeds. This study was used variations in concentrations of 0.25%, 1%, 1.75%, 2.25%, and 3%. The results of this study showed that the best concentration is 2.25% with the calculation of the results of 24.8% methyl esters in avocado seeds, namely lignoceric and octadecenoic acid methyl ester. Keywords: Avocado seeds, fatty acid methyl esters

Abstract The course of the reaction between lauric acid and monoethanolamine as well as the reaction of methyl laurate with monoethanolamine and diethanolamine were investigated. Thin layer chromatography with flame ionisation detector was used for reaction mixture analysis. The fatty acid methyl ester is more suitable for production of monoethanolamide and diethanolamide. Sodium methoxide or potassium hydroxide (0.02 mol % ester) was used as suitable alkaline catalysts of reaction. The optimal temperature of methyl laurate or coconut oil with diethanolamine reaction is 80°C. Higher temperatures (over 100°C) lead to a higher concentration of amide ester in the product.

Waste coconut oil obtained from waste water pond contains high free fatty acid (FFA) which is not suitable to produce biodiesel via transesterification. The two steps of reaction (esterification and transesterification) were used to produce biodiesel from waste coconut oil. The result showed that FFA decreased from 92.95%wt to nearby 2%wt under the conditions of 80%vol of methanol to oil, 4%wt of hydrochloric acid and 4 h of reaction time in esterification step. In addition 95.34%wt conversion of fatty acid methyl ester (FAME) could be achieved in 1 h when 20%vol methanol to oil and 0.5%wt of sodium hydroxide in transesterification step. The fuel properties of waste coconut oil biodiesel were mostly met well within the ranges specified in biodiesel standard.
