Perancangan Struktur Penopang Tangki Penyimpanan Amonia

This study to obtain reinforcement in the supporting structure of the ammonia storage tank which consisting of wall slab and top slab. Fisrt, done the modeling structure that will analyze and provide load acting on the structure. For modeling and loading on wall slab author use the program etabs v.9, while the top slab used for the safe program v.8. Special for top slab reinforcement analysis using the program. The results for top slab reinforcement consist of reinforcement x directions and y direction (see appendix 2), so that obtain the bottom reinforcement of x direction : d13 - 200, the bottom reinforcement of y direction : d13 - 200, the top reinforcement of direction x direction : d13 - 200, and the top reinforcement of y direction : d13 - 200. There are two types of wall slab, which is exterior wall and interior wall. Reinforcement in the walls consist of vertical and horizontal bars (see appendix 2), so that obtain the vertical exterior wall reinforcement: d13 - 200, horizontal exterior wall reinforcement: d13 - 400, vertical interior wall reinforcement: d13 - 350, horizontal interior wall reinforcement : d13 - 350. As a coupling between the wall slabs is used couple beam (spandrel), and results of spandrel reinforcement consist of main top reinforcement: 5 d13, the main bottom reinforcement : 5 d13, shear reinforcement : 2 d10 - 100, and shrinkage reinforcement : 2 d13. Keywords: reinforcement, top slab, wall slab, spandre

Penentuan Kondisi Optimum Fermentasi Menggunakan Lactobacillus Bulgaricus dalam Pembuatan Tepung Suweg (Amorphophallus Campanulatus) Terfermentasi

This aims of this study is to determine the optimum conditions and characteristics of fermented suweg flour. The optimum conditions are determined based on the maximum levels of lactic acid produced in the fermentation process. Fermentation conditions are studied based on the variation of pH (3,4,5,6,7), temperatur (30oC, 35oC, 40oC, 45oC, 50oC) and incubation time (3,6,9,12,15 hours) The characteristic of fermented and non fermented suweg flour include starch, amylase, amylopectin and expands power. The optimum fermentation conditions achieved at pH 6, temperatur 45°C, and 12 hours of incubation time. The characteristics of fermented suweg flour at the optimum conditions reach higher starch, amylose, amylopectin and expands power, better than non fermented flour. The contents of starch, amylose, and amylopectin in the non fermented suweg flour are 83.7%, 11.72%, 71.98% respectively. The content of starch, amylose, and amylopectin in fermented suweg flour are 87.3%, 12.15%, 74.82% respectively. Expands power of non fermented suweg flour is 35.29%, while expands power in fermented suweg flour is 41.18%. Key words: Fermentation, Flour, Lactobacillus bulgaricus, Suwe

The Effects of Fire on Organic Functional Groups of Peat in Relation to Water Content

The aim of this research was to study the decline of organic functional group through the process of burning in peat. In addition, this study was also to examine the relationship between water content in peat and organic functional group after combustion (burning).  Peat drying was conducted in an oven at a temperature of 75°C with the interval of 0, 1, 2, 3, 4, 5 and 6 hours.  Each time interval had three replicates within two sets of experiments so that the total number of samples were 42 (experimental units).  Variables measured were moisture content, total acidity, COOH groups, and OH-phenolate.  The relationship between the water content with total acidity, COOH groups and OH-phenolate were determined by the equation y = bx + a.  The results showed that the relationship between the water content with organic functional group was linear.  While the relationship between peat water content with organic functional group after burning was irregular, although water levels through the process of burning have been greatly reduced. Keywords: Burning peat; organic functional groups; water content [How to Cite: Said R, FH Yusran, A Haris and S Asmawi. 2014.

Kajian Indeks Pencemaran Air pada Areal Pertambangan Rakyat Intan dan Emas di Kecamatan Cempaka Kota Banjarbaru

This research aimed to determine waters condition based on several water indicators of physical-chemical parameters (TSS, pH, DO, temperature, turbidity, Hg and Fe), mercury's content of sediment (Hg), and biological parameters of water that is mercury's content (Hg) of gondang (Pila scutata) the level of water pollution and and analyze in the diamond and gold traditional mining activities at district of Cempaka. The results showed that the water conditions at the station I which is close to the mine site are still fulfill standard of water quality that are temperature, DO and COD according to the results of calculations using the Storet method and included in the category of heavily contaminated. Based of the Pollution Index method categorized low polluted. At the second station which is a mining area, the temperature still fulfill water quality standards, while for the other parameters based on calculations using the Storet method included in the category of heavily polluted. Based on the Pollution Index Method, stations II included in the category of medium polluted. At the third station, which is far from the mine site the parameters of temperature, pH, DO, COD and Fe still water quality standards, but the results of calculations using the Storet method included in the category of heavily polluted. Based on the Pollution Index Method according to Regulation No.82 of 2001, the station III was included in category good condition, while according to the Minister of Health Indonesia No.416/Menkes/Per/IX/90 included in the medium category. So the results of this research for the parameters pH, DO, COD, turbidity, TSS, Fe, Hg water, sediment Hg and Hg gondang not fulfill the quality standards of Government Regulation No.82 of 2001 on Water Quality Management and Pollution Control for the class II and hygienic water requirements in accordance with the requirements of RI Permenkes No.416/Menkes/Per/IX/90
