Abstract

Telah dilakukan reaksi penataan ulang Fries pada eugenil asetat yang bertujuan untuk mengetahui pengaruh gugus allil yang terdapat dalam eugenil asetat. Reaksi penataan ulang Fries eugenil asetat dilakukan dengan pemanasan menggunakan katalis AlCl3, pelarut diklorometana pada temperatur 120 °C selama 3 jam. Identifikasi struktur hasil sintesis dilakukan dengan menggunakan Spektrometri inframerah (IR) dan GC-MS. Hasil penelitian ini menunjukkan bahwa reaksi penataan ulang Fries pada eugenil asetat tidak terjadi, namun membentuk dimer eugenil asetat yang berupa cairan kental coklat kehitaman.

Abstract

Cross cultural training is widely believed to make a positive contribution to expatriate adjustment. In practice, however, it is very costly and sometimes ineffective for expatriates. Therefore, there is a growing importance placed on increasing the cost effectiveness or enhancing the efficacy of crosscultural training by functioning individual expatriate’s social capital and emotional intelligence as moderating variables towards expatriate’s adjustment and performance. To do so we blend ideas drawn from social capital theory and emotional intelligence to develop the structure that underlies the logic of this paper. Thus, this paper uses social capital and emotional intelligence theories to enrich extant literature on expatriate adjustment

Abstract

Corruption is a classical phenomenon but still interesting to be discussed. Corruption does not only contribute to negative impacts on the economic growth but also generates negative impact on the moral ground of the entire country. Many studies have investigated the determinants of corruptive behaviors. Of toe studies, two dominant approaches have been used including by previous scholars to explain corruption phenomenon; economic approach and organizational behavior approach. In this study the organizational behavior approach is used including the use of social information processing theory to theoretically explain why good people are trapped to corrupt when they are part of public organization. Detailed reason why this approach is used and how the social information processing theory explains logically the corruptive behaviors in organization ate further discussed.

Abstract

Fatty acid methyl ester (FAME) merupakan bahan bakar alternatif pada mesin diesel yang terbarukan. Penelitian ini mensintesis FAME melalui transesterifikasi minyak biji mahoni dengan metanol menggunakan katalis KOH. Tujuannya (1) mendapatkan kondisi optimal sintesis FAME, (2) mengetahui sifat fisis FAME, dan (3) mengetahui performancenya. Minyak biji mahoni memiliki bilangan asam yang tinggi (29,86 mg KOH/ g minyak) sehingga dilakukan esterifikasi. Esterifikasi dilakukan pada suhu 35°C menggunakan katalis H . Transesterifikasi dilakukan dengan perbandingan minyak: metanol= 4:1. Variasinya suhu (30°C - 60°C) dan konsentrasi KOH (0,5% - 1% berat minyak). Didapatkan kondisi optimum reaksi transesterifikasi pada suhu 60°C, konsentrasi KOH 0,75%, waktu reaksi 60 menit, serta rasio volume minyak:metanol= 4:1, dan didapatkan yield sebesar 83,9742%. FAME diuji sifat fisisnya dengan variasi perbandingan FAME:solar: butanol sebesar 1:0:0, 1:1:1, dan 1:2:2. Pengujian meliputi densitas, korosi lempeng tembaga, color ASTM, viskositas kinematis, flash point, pour point, kandungan air, serta CCR. Hasilnya dibandingkan dengan standar kualitas biodiesel (SNI). Data menunjukkan bahwa semua komposisi campuran FAME:solar belum memenuhi persyaratan standar. Uji performance secara lengkap belum dapat dilaksanakan karena dapat menyebabkan kerusakan mesin, tetapi performance konsumsi FAME pada mesin diesel tidak jauh berbeda dengan konsumsi solar pada mesin diesel, tetapi emisinya lebih rendah.

Abstract

Fries Rearrangement of eugenyl acetate in order to study allilic substituentgroup influence has been done. Fries rearrangement of eugenyl acetate was done byheating at 120°C for 3 hours under AlCl3, dichloromethane as the catalyst and solvent,respectively. The structure of the compound was identified using Infra Redspectrometry (IR) and GC-MS. The result of te research showed that rearrangementfries of eugenyl acetate are not formed, but yielded lightly brown oil of dimmer.

Abstract

This research was aimed to utilize eugenol isolated from clove leave oil in the synthesis of isoflavones. Eugenol was usedas a raw material by converting into 3,4-dimethoxybenzyl cyanide through several stages of reactions. These stages weremethylation of eugenol, isomerization of methyleugenol, oxydation of methylisoeugenol, reduction of 3,4-dimethoxybenzaldehyde, halogenation of 3,4-imethoxybenzyl alcohol and nitrilization of 3,4-dimethoxybenzyl chloride to3.4-dimethoxybenzyl cyanide. Methylation of eugenol using dimethylsulfate and NaOH catalyst produced methyleugenolin 93.60% purity. Isomerization of methyleugenol employing base of potassium tertiary butoxide (t-BuOK) in dimethylsulfoxide (DMSO) gave methylisoeugenol with 87.15% yield and 98.10% purity. Oxidation of methylisoeugenol usingpotassium dichromate (K 2 Cr 2 O 7 ) was performed catalyst transfer phase (CTP) system of polysorbate 80 to 83.40% 3.4-dimethoxybenzaldehyde yield and 90.20% purity. Reduction of 3.4-dimethoxybenzaldehyde with sodium borohidrat (NaBH 4 )produced 98% yield. Halogenation of 3,4-dimethoxybenzyl alcohol by SOCl 2 to 3,4-dimethoxybenzyl chloride followed bynitrilisation using sodium cyanide produced 3.4-dimethoxybenzyl cyanide with 83.90% purity after reflux for 20 hours.
