Abstract

(±)-Citronellal and its derivatives were converted to (-)-menthol by a one-pot reaction system using zeolite based nickel catalysts. The catalysts were prepared by immobilization of nickel on natural zeolite (NZ) or synthetic zeolite (ZSM-5) by a simple cation exchange method. Calcination and hydrogen treatment procedures were able to significantly increase the surface area and pore volume of NZ based catalysts whereas negligible changes in the properties were observed for that of ZSM-5. Catalytic reactions were carried out at 70ºC by stirring the mixture in the air for cyclization of (±)-citronellal to (±)-isopulegol followed by hydrogenation towards the desired (-)-menthol at 2 Mpa of H2 pressure. The Ni/NZ catalyst was able to convert a (±)-citronellal derivative yielding 9% (-)-menthol (36% selectivity) with conversion up to 24%, whereas Ni/ZSM5 catalyst directly converted 65% (±)-citronellal to give 4% menthol (6% selectivity). These zeolite based catalysts are therefore potential materials for the conversion of biomass feed stock to value-added chemicals.

Abstract

The solid waste of iodized-salt industry are sapon (50-100 kilograms) and blotong (1-2 tons) per 10 tons per day. The objective of this research was for recycling blotong through purification, recrystallization and in situ iodisation to increase NaCl content and homogeneous KIO3. This research used two variables which were KIO3 concentration within 30,40, 50 & 60 ppm, and brine water of blotong that had soluted into 240Be (consist of salt water which purified with Na2CO3, NaOH and unpurified salt water). The composition of blotong were 12.318% water content, 46.409% Cl-, 82.685% pure NaCl, 0.784% Mg2+, 1.420% Ca2+ and 2.747% SO4.After purification and recrystallization, impurities was decreased, Mg2+ became 0.278% (64.54% reduction) and Ca2+ became 0.153% (89.23% reduction). NaCl content was increasing into 96.481% and fulfilled the NaCl standard of salt consumption based on SNI 3556-2010 (94.7%).

Abstract

Research utilization of liquid smoke from oil palm empty fruit bunches of raw rubber has been made to utilize solid waste from industrial processing of oil palm empty fruit bunches of oil palm so that it becomes economically valuable products. This research has been done by pyrolysis of oil palm empty fruit bunches at a temperature of 400oC for 5, 6, 7 and 8 hours. The results show that the pyrolysis liquid smoke oil palm empty fruit bunches for 8 hours give a high concentration of phenol and acetic acid, respectively 5% and 0.454%. Liquid smoke that has been obtained is used as a coagulant in raw rubber plantation crops of the people residing in the village of Ambawang, Kubu Raya District, West Kalimantan. Results of treatment of liquid smoke on raw rubber  show that the rubber products that have been frozen and dried are superior in terms of color, smell and drying time compared with the treatment of formic acid and water battery which has been added so far on raw rubber by the local rubber farmers.

Abstract

Fenol is a hazardous substance that can pollute the environment. Traditional herb Industry is one of industries produces liquid waste with high pollution level, the fenol content more than 9 mg/L.  Biological treatment  with anaerobic activated sludge method is one effective way of processing waste.This research was aimed to study the effect of MLSS variable and fenol load, the efficiency of fenol decrease in anaerobic waste processing system. The experiment is conducted by synthetic herbs waste with COD content of ± 3610 mg/L, retention time of 6 hours at a temperature of 30oC, atmospheric pressure in anaerobic baffle reactor continuously. The reactor volume is 60 L, the MLSS content of 3000; 4000; 5000 mg/L,  fenol load at 0, 3, 6; 9; 12 mg/L. Result of research show that active sludge of mixture breeding  from cage manure effective for the processing of waste with the low rate fenol (less than 6 mg/L) with the efficiency of degradation fenol 89,7-99,87% but less be effective at high burden fenol (more than 6 mg/L) with the efficiency of degradation fenol equal to 18-52%. The results obtained compared well with other reduction process.

Abstract

So far, most of West Kalimantan cocoa beans sold raw to collectors in Malaysia at a price that is less competitive, so it was necessary to study the processing of cocoa into chocolate bars with products utilizing palm fat as a fat substitute. The purpose of this study was to determine the effect of the formulation of palm fat and cocoa fat on the physical properties of chocolate bars. The research was conducted by varying the concentration of palm fat to total fat namely 0%, 25%, 50% and 75%. The products were tested on melting point and hedonic. Based on research data it can be concluded that the treatment of palm fat concentrations to total fat by 25% produces chocolate bars with a melting point of 36.0 ° C and preferred by the panelist.

Abstract

Gambier liquid waste is a by-product from gambier (Uncaria gambier Roxb.) processing plant,  which is still contains a lot of untapped tannin. This waste could be used for textile dyes, but it is easily damaged during storage. So, the aim of this research is to treat gambier liquid waste so it could be used as silk dye. This research was carried out by concentrating the waste and using stabilizers such as lime (K), alum (T), lotus (F). The parameters tested include pH and fungal growth for up to three months. The results of the process could generate several different colors which is brownish red, brownish yellow and dark green. The waste could save more than 3 months. The color of the waste generated depends on stabilizer type and pH. The use  waste on silk produced brownish red color, golden yellow  and moss green to dark green.

Abstract

Bioethanol gel is a new form of liquid bioethanol that has been given a thickening agent. This type of bioethanol is believed could make its transportation and utilization safer. This study aimed to compare the carbopol and carboxymethyl cellulose as thickener agents and to characterize the bioethanol gel produced. In this research, carbopol and carboximethyl used for making bioethanol gel were1.5, 3, 4.5 and 6 g. Then flame color, length of flame and viscosity were tested. The best bioethanol gel produced obtained on the addition of carbopol 6 g. Its characteristics were clear white color, the flame color is blue reddish, length of flame per 5 g is 5 minutes 17 seconds, and viscosity 1,380,000 cP. The boiling water test result on 100 ml of water by using 15 g of bioethanol gel takes 16 minutes.
