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 purpose  of this study was to determine the effect of the white maize starch by oxidation and acetylation-oxidation modification on gel formation and character of the resulting gel, and applying a modified white corn starch in manufacturing of marshmallow cream. White corn varieties Srikandi, Pulut and Canggal are used as raw materials to produce starch. Starch modification is conducted by oxidation and acetylation-oxidation. Quality analysis of the modified starch is freeze thaw stability, smallest gel formation concentration and gel strength. Corn starch, both native and modified applied in manufacturing of marshmallow cream. The results showed that the treated starch acetylation-oxidation provide the best freeze thaw stability with the least water released than native starch and modified starch oxidation. Starch modified by oxidation tend to have the highest Least Gelling Concentration (LGC). Gel produced from modified starch both oxidation and acetylation-oxidation has a gel strength greater than the native starch. Marshmallow cream that uses a modified starch by acetylation-oxidation, have the best received power in testing organoleptic by the panelists. Use of modified starch does not give a noticeable difference in color of the product, but it gives texture and the best spread power compared to products using original starch.

Abstract

This study aimed to evaluate protein quality of top leaf meal of Indigofera zollingerina based on its net protein utilization (NPU) as well as to evaluate its metabolizable energy. Fifty broiler chicks were used in determination of NPU while fifteen broiler strain Cobbs chickens aged 5 weeks were used for metabolizable energy measurement. This study used descriptive method in which data obtained were analyzed and compared to NPU and metabolizable energy of soybean meal. The results showed that top leaf meal of Indigoferazollingerinahad NPU of 38.58 – 46.98, which is 70.14% - 85-42% of that of soybean meal (55). Its metabolizable energy was 2791.12 kcal/kg and was 9.46% higher than that of soybean meal. As the NPU and metabolizable energy were close to those of soybean meal, top leaf meal of Indigoferazollingerinacan be used to substitute protein from soybean meal in poultry feed.

Abstract

A Study of physicochemical and microbiology analysis in Ogan River Kabupaten Ogan Komering Ulu was carried out in Mei-Juny 2016. The purpose of this study was to determine the water quality status of Ogan River by using National Sanition Foundation Water Quality Index. Water quality status was studied at six selected stations to represent different localities with varying anthropogenic discharge. Water samples were taken by purposive sampling method. Physicochemical and microbiology parameters of samples were measured pH, temperature, Turbidity, Total Suspended Solids, Dissolved Oxygent, Biochemical Oxygent Demand, Nitrat, Phospate, and Fecal Coliform following standard method. The river water quality status is medium, the value ranged 56-57. Based on these indices it is concluded that the anthropogenic activies along Ogan River effected quality of water Ogan River.

Abstract

The purpose of this study was to evaluate the effect of a complete ration silage made of cassava biomass  nitrogen retention, and metabolizable energy male ducks. Control diet consisted of corn, rice bran, coconut meal, soybean meal, vegetable oil, fish meal and premix. While the treatment of silage ration of cassava based (BBS) consisted of leaves, peel, and tubers of cassava, as well as a mix of fish meal, vegetable oil, premix, DL-methionine and L-lysine. The experimental design used was completely randomized design with 5 treatments and 4 replicates ie S0 (100% control diet), S25 (75% control diet + 25% BBS silage), S50 (50% control diet + 50% BBS silage), S75 (25% control diet + 75% BBS silage), and S100 (100% BBS silage ration). Measurement of metabolizable energy and nitrogen retention was conducted using 25 male ducks aged 10 weeks maintained in metabolic cages and adapted to experimental diets for seven days. Ducks were fasted for 24 hours before the experimental diets were offered. Metabolizable energy and nitrogen retention were measured by the method of Sibbald (1989). The results showed that a decline in nitrogen retention and, metabolizable energy along with the increasing level of BBS silage in the rations. The conclusion of this study was the use of up to 75% BBS silage generated metabolizable energy and nitrogen retention that do not differ from the control ration.Key words: cassava silage, complete ration, male duck, metabolizable energy, nitrogen retention

Abstract

The optimum performance of duck farm can be achieved by providing them with good quality rations. Rations with good digestibility will increase the productivity due to large amount intake of nutrients. Chitosan is type of animal fibre which assisted the growth of useful microbes in digestive system. Addition of chitosan in cattle rations will improve the ecologic of duck digestive system to be more conducive.  The aimed of the research was to evaluate rations digestibility with the addition of chitosan. The research was used completely randomized design with 4 treatments and 5 repetitions. Each repetition consists of 2 ducks. The treatments are R0 stands for rations without chitosan and R1-R3 with addition of chitosan 0.5%, 2% and 2.5% respectively. Parameter measured were dried matter digestibility, organic matter and crude protein. Data processing was conducted by using SAS Windows 16. Result showed chitosan addition at 0.5% and 2.5% gave dried matter digestibility and crude protein does not higher than control (P>0.05) while chitosan addition at 2% gave result lower than control. Organic matter digestibility displays balanced in value.Keywords: Chitosan, Dried matter digestibility, organic matter, crude protein, rations.
