Abstract

Analysis of essential oil contained in Flores’s Melaleuca cajuputi Powell leaves has been done over GC-MS spectrometer. By distilling of the pre-dried leave samples using Stahl apparatus, there was 3% of colorless and cajuputi typical oil yielded. The GC-MS detected 16 compounds mainly 63% of 1,8-cineol, 11% of α-terpineol, and 12% -terpenylacetate.

Abstract

It has been done a study of mono acyl glycerol compound synthesis through partial transesterification of castor oil (Ricinus communis L.) using KOH as catalyst. The product of mono acyl glycerol obtained is 45.4 % with the ratio between castor oil triglyceride and methanol 1:2 at 35 0C temperature with the amount of catalyst 0.5 % (b/b) from the reactant total weight and the reaction time 30 minutes. In this research, it was done a compound characterization using, TLC, FTIR and LC MS to prove the success of targeting compound has been synthesized.

Abstract

A research conducted about effect of bioaktivator of cow feces and gamal (gliricidiasepium) leaves with sweet potato nutrition toward the compost quality. This research hadpurpose to know the compost characteristics of cow`s dung composition and gamal. Thecharacteristic determined to 60% of cow`s dung and 40% gamal leaves used purple sweetpotatoes nutrition and water that made constant. The variation of cow`s dung and gamal leaveswas 90%: 10%, 50%: 50%, 30%: 70%. The research result show that in the 14th days therewere compost characteristics to produce compost based on SNI 19-7030-2004 andrequirements of the minister of agriculture number 70/Permentan/SR.140/10/2011. Thevariations of cow`s dung and gamal leaves did not effect towards C/N ratio compost.

Abstract

The study about Synthesis of Ethyl Stearate through Esterification Reaction of Stearic Acid and Ethanol Using Sulfuric Acid Catalysis had carried out. The purpose of this study is to know how to synthesize Ethyl Stearate from esterification reaction of stearic acid and ethanol using sulfuric acid catalyst. Characterization of Ethyl Stearate compound was done using FT-IR and GC-MS. The study result exhibits that the yield of Ethyl Stearate product obtained is 98.85 %. Through characterization using FT-IR and GC-MS can be concluded that Ethyl Stearate compound is successfully synthesized and its purity reaches 98.87%.

Abstract

Biodiesel is a concern for many parties because it is environmentally friendly, non-toxic, and renewable. One of the problems faced in the use of biodiesel as an alternative energy is the process of purification from impurities and by-products such as glycerin which is complicated and expensive. Glycerin can cause saponification, increase ignition delay, incomplete combustion, blockage and increase engine maintenance costs. In this study, deep eutectic solvents (DES) synthesized from choline chloride (ChCl) salts and tannic acid were used as extractants for the extraction of glycerin from biodiesel synthesized through palm oil transesterification with methanol as a trans substituent and KOH as a catalyst. The effect of the composition of the constituent moles of DES and the ratio of biodiesel-DES mass to glycerin content of biodiesel has been studied. The results showed that the higher the content of ChCl salt in DES and the greater the ratio of biodiesel-DES, the lower the glycerin content in biodiesel, with the highest decrease of 65.7693% (glycerin content after extraction of 2.0193%) obtained from the composition of the mole DES 1:47 (Tannic acid:ChCl) and the mass ratio of biodiesel-DES 1:3. The biodiesel produced has not met SNI 1782, which is 0.02%.

Abstract

Minyak biji kemiri merupakan salah satu minyak nabati yang dihasilkan dari biji kemiri melalui proses ekstraksi soxhlet. Minyak biji kemiri dapat disintesis menjadi FAME karena mengandung komposisi asam lemak yang tinggi dengan catatan dilalukan proses penetralan sebelum disintesis menjadi FAME. Tujuan penelitian ini untuk mengetahui rendemen minyak biji kemiri dengan menggunakan metode ekstraksi soxhlet, mengetahui % rendemen FAME hasil sintesis melalui proses transesterifikasi setelah penetralan minyak dan uji sifat antibakteri FAME dari minyak biji kemiri terhadap bakteri Staphylococcus aureus dan Escherichia coli. Hasil penelitian memperoleh rendemen minyak sebesar 80,2%, rendemen FAME sebesar 68,4% dan sifat antibakteri FAME minyak biji kenari yang diuji menunjukan daya hambat terbesar terdapat pada bakteri S. aureus dengan diameter hambat sebesar 14,3 mm pada konsentrasi 20% sedangkan daya hambat FAME terhadap bakteri E. coli dengan diameter hambat sebesar 13,1 mm pada konsentrasi 20%.
