Indonesian Journal of Fundamental and Applied Chemistry (IJFAC) is an international research journal and invites contributions of original research articles as well as review articles in several areas of chemistry. The journal aims to publish refereed, high-quality research papers with significant novelty and short communications in all branches of chemistry. Papers which describe novel theory and its application to practice are welcome, as are those which illustrate the transfer of techniques from other disciplines. IJFAC calls for papers that cover the following fields: Biochemistry Inorganic chemistry Physical chemistry Organic chemistry Analytical chemistry Applied Chemistry All papers are peer reviewed by at least two referees. Papers presented at conferences are peer reviewed and selected with the same standards as individually submitted papers. They therefore have the same archival value. Article should be submitted by the Online Submission Module at www.ijfac.unsri.ac.id or email to ijfac@unsri.ac.id

Abstract

The research was aimed to obtain the level of organic minerals supplementation with Total mixed fiber Amoniation (TMFA) as basal feeding for the improvement of nutrient digestibility in rumen. Technique of research conducted by In Vitro technique. The method used in this research is a Completely Randomly Designed (CRD) with 4 treatments and 4 replications. P1: 60% amoniation TMF + 0 x Organic macro minerals (Ca, P, and S) NRC (2000) + 15% Swamp Legumes. P2: 60% ammonia TMF + 0.75 x Organic macro minerals (Ca, P, and S) NRC (2000) + 15% Swamp Legum, P3: 60% ammonia TMF + 1 x Organic macro minerals (Ca, P, and S) NRC (2000) + 15% Legum Swamp P4: 60% amoniation TMF + 1.5 x Organic macro minerals (Ca, P, and S) NRC (2000) + 15% Swamp Legum. Each treatment was added with an organic micro-mineral consisting of 40 ppm organic Zn, 10 ppm organic Cu, 0.10 ppm organic Se, and 0.30 ppm organic Cr. The parameters measured in the in-vitro technique were, measurement of nutrient digestibility which consists of dry matter and organic matter, crude protein, crude fiber, NDF and ADF. The results showed that organic mineral supplementation had significantly different effect (P <0.05) on nutrient digestibility (dry matter, organic matter, crude protein, crude fiber, ADF, NDF). The conclusion of this study was that organic mineral supplementation of Ca, P and S 1.5 times of requirement according to NRC (2000) gave the best results for in vitro nutrient beef digestion with Total mixed fiber ammoniation (TMFA) as basal feed and supplementation of l5% legume swamp (Kemon air).Keywords: Amoniation, total mixed fiber, organic mineral, nutrient digestibility

Abstract

A triterpenoid compound has been isolated from the ethyl acetate fraction of Lantana camaraLinn leaves. The isolation was performed by chromatography of gravitation column with a gradient elution system using hexane, ethyl acetate and methanol. Purification by recrystallization produces a white solid (20 mg) with a melting point of 288-289 °C. The results of elucidation of UV, IR, 1H-NMR, 13C-NMR, HMBC, HSQC, DEPT and COSY spectral data, it is known that the isolated triterpenoid compound is 22β-angeloyloxy-9-hydroxy-3-oxo-olean-12- en-28-oicacid with molecular formula C35H52O6. Keywords—Lantana camaraLinn, Chromatography of gravitation column, Triterpenoid, C35H52O6

Abstract

Nowadays, environmental pollution caused by industrial wastewater is quite apprehensive. Most of textile industries used synthetic dyes. Procion red is one of the synthetic dyes that often used in textile industries and classified as a reactive dye that is difficult to decompose in nature and contain harmful toxins. One of the colored wastewater treatment process is by using Fenton reagent and TiO2 catalyst (Fenton-TiO2) as one of Advanced Oxidation Processes (AOPs). The objective of this research is to treat of procion red synthetic dye by using Fenton-TiO2 method and study the effect of procion red concentration, reaction time and the concentrations of TiO2 catalyst on color and COD degradation. In this experiment, the concentrations of procion red were varied between 150-300 ppm, the concentrations of TiO2 catalyst were varied from 0.05 to 0.4% (w/v) and the reaction time of 5 to 20 minutes. The optimum condition was achieved by using procion red concentration of 150 ppm with TiO2 catalyst concentration of 0.4% and reaction time of 20 minutes, which the maximum color and COD degradation of 98.67% and 92% were achieved respectively. This condition was applied to the real wastewater of textile home industry in Palembang. The color and COD degradation of 59% and 44% were found respectively after 220 minutes of reaction.

Abstract

Formation of nanotube morphology on the surface of Ti-6Al-4V metal did not occur homogeneously, so when it was coated with hydroxyapatite, it did not merge well. One of the factor that affected the inhomogeneously formed nanotube was the utilization of electrolyte solution. The research has been done to observe the effect of electrolyte solution in the formation of nanotube morphology on the surface of Ti-6Al-4V metal alloy. Electrolyte solution that was used was ethylene glycol, HF, and NH4F with time variation of an hour, 2 hour, and 3 hour. Formation of nanotube morphology on the surface of Ti-6Al-4V metal alloy was done using anodization process. The result showed that in HF electrolyte solution which was anodized for an hour ɑ and β phase that composed Ti-6Al-4V metal alloy was formed, meanwhile when using electrolyte solution of ethylene glycol  + NH4F for 2 hours showed that there were pores that opened on Ti-6Al-4V metal alloy surface. Nanotube morphology on the surface of Ti-6Al-4V metal alloy was formed using electrolyte solution of ethylene glycol + NH4F which was anodized for 3 hours.

Abstract

This study aims to separate glycerol from used cooking oil biodiesel products. This research is done by main process by analyzing free fatty acid level (FFA) to know the fat content of the oil in order to know the next process. This research is done by electrolysis process using high voltage. We done transesterification process by using methanol and NaOH as catalyst before performing the process of electrolysis with high voltage. Biodiesel is manufactured using a mini-scale stirred tank reactor (RATB) laboratory. This process is heated at temperature (35-60) oC, the ratio of used cooking oil and methanol (5:1, 6:1, 7:1, 8:1, 9:1) using a 0.1 N NaOH catalyst. The research obtained optimum reaction temperature yield highest percentage of rendement at temperature 60oC and ratio of used cooking oil and methanol 5:1 with percentage of rendement equal to 88,88, cetane number 48,4, kinematic viscosity 2,560, pour point 37,4 oF, flash point 131 oF, Conradson Carbon Residue (CCR) 0.09, and ASTM Colour 1.5. This shows that the manufacture of biodiesel with high microwave and high voltage utilization yields a high percentage of 88.88 and the product is biosolar-48.
