Abstract

The completion of human genome project at beginning of 21st century with the advancement of computer technology has transformed Biochemistry into a genomic era. Further, it is accelerated by parallel and massive genome sequencing technology known as next generation sequencing (NGS) that enhances the identification of genetic variants associated with complex diseases such as cancer, diabetes and Alzheimer. Currently, this knowledge has been driving the development of precision and personalized medicine. Wisely applied, it is believed that the explosion of genomic big data can be of great use in advancing the diagnosis, therapy and drug discovery to combat complex diseases.

Abstract

A research on the conducted on the use of fly ash as an adsorbent in used cooking oil. This research was conducted with the aim to know the characteristics of fly ash without activation and activation with 6M HCl and to improve the quality of used cooking oil from adsorbent processing based on the Indonesian national standard (SNI). This research was conducted in several stages, namely surface acidity with the titration method, determination of surface area with the blue methylene method, determination of functional groups by FTIR analysis and oil quality based on parameters of acid number, peroxide number and smoke point. The results showed that the acidity of the surface of the fly ash was activated and without activation of 4 and 3.6 m2 / g respectively. surface area of ​​fly ash without activation 17,480 m2/g at contact time 80 and activated fly ash 18,471 m2/g at contact time 70. FTIR spectra of fly ash without activation 795,38 and 779.95 cm-1 and activated 795.38 and 778,02 cm-1 which is a symmetrical stretching adsorption band of symmetric ≡Si-O (≡Si-O-Si≡). Fly ash used for refining used cooking oil (2,468 mg KOH / g) is able to reduce the acid number 0.361 mg KOH / g in activated fly ash and 0.561 mg KOH / g for fly ash without activation, the peroxide number for activated fly ash decreased by 72.34% compared to fly ash without activation 69.14%, oil smoke point purification results from activated fly ash 203ºC and without activation 210ºC which is close to the new oil smoke point value of 200ºC. When compared with SNI, the values ​​of acid numbers, peroxide numbers and smoke points meet the standard.

Abstract

A study of the essential oil content in basil (Ocimum sanctum) and red lemongrass (Cymbopogon nardus L. Rendle) originally grown in Flores island has been conducted. The purpose of this study was to identify the chemotype of the essential oils obtained over stahl distillation using GC-MS. The Ocimum mainly consisted of 55% eugenol following by minor trans-alfa-bergometena, patchulana, and linalool. Meanwhile, the chemotype of the red lemongrass (Cymbopogon nardus L. rendle) were citronellol (22%), citronella, cyclohexamethanol, and viridiflorol.

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.
