MODEL SISTIM INFORMASI GEOGRAFIS UNTUK ESTIMASI VOLUME ALIRAN DAN EROSI SEDIMEN DI DAS RIAM KANAN PROVINSI KALIMANTAN SELATAN
Get PDFIn determining the estimated volume flow, required an appropriate model toestimate the value of the volume flow of a watershed. It has been a decline in the carrying capacity of the Sub Watershed of Riam Kanan as the catchment area due to critical land cover. This study aims to estimate the flow of volume and its distribution in the Riam Kanan Watershed based on data Landsat7 ETM + Satellite Imagery.The results yield a regression equation Qp = 0.007p + 56.85 regression rate of 89.6%, indicating that land cover can lead directly to changes in flow volume in the sub watershed of Riam Kanan By using the data flow volume recorded on board thought the water reservoir (DMA) and data rains cause, the lowest flow volume data obtained in the lowest in Rantau Balai amount of 2.14 m3/sec and the highest in the Rantau Bujur amount of 17.65 m3/sec. As for the areas Bunglai, Tiwingan, Kalaan and Belangian have moderate flow volume ranged from 2.16 m3/sec - 6.59 m3/sec

Penelitian ini bertujuan (1) mengkaji faktor penyebab menurunnya kualitas pH pada air bekas galian penambangan intan di Cempaka, (2) mengkaji proses kapur gamping memulihkan pH air bekas galian penambangan intan di Cempaka, (3) dosis kapur gamping yang tepat diberikan agar peningkatan nilai pH air asam bekas pertambangan intan berada pada kisaran baku mutu. Penelitian dilakukan dengan metode survei untuk memperoleh informasi faktual dan metode eksperimen dalam mencari pengaruh perlakuan tertentu terhadap pH air dalam kondisi yang terkendalikan
RENDEMEN DAN KOMPOSISI PROKSIMAT GELATIN KULIT IKAN BELUT DAN LELE PADA KEADAAN SEGAR DAN KERING
Get PDFSkin of swam ell and catfish were potential to gelatin extracted. Swamp ell skin doesn’t have scales, with much mucus and a few fat for catfish, it’s different from another fish skin that gelatin extracted usually. This research was studied yield and proximate gelatin extracted from skin of swam ell and catfish. Influence of drying was observed too.The first stage of the research was raw material preparation (fresh and dryfish skin) soaked in aquadest for 4 hours. Fish skin extracted using 0,05 M aceticacid for 10 hours, washed in water and then extracted using aquadest at 80oC for 2 hours to get gelatin liquid, the liquid was filtrated. Filtrat was dried in cabinet dryerat 55oC for 48 hours to get gelatin layers, and then blended to get gelatin granule.The results were gelatin yield from dry fish skin lower than fresh fish skin. Gelatin protein from dry fish skin more higher than fresh skin. Influence of fish skin drying was decrease gelatin ash and fat, but gelatin moisture wasn’t influenced. Gelatin from fresh skin swamp ell was the best gelatin with moisture 9,91%, ash 3,07%,protein 91,61%, lipid 0,82%

Get PDFThis study aims to determine the feed Arowana fish seed (Scleropagesformosos) after feeding egg yolk tobe variations between, mosquito larvae bloodworms-mosquito larvae(A), crickets-mosquito larvae-crickets(B), and bloodworms-crickets- blood worms(C), are maintained in the container cultivation.Overall implemented for ±5 months from January 2013 to May 2013 in the month of PT. Kresna Pusaka Tirta Lestari Jln. Kuripan. No. 19D RT. 33, Eastern District of Banjarmasin, Banjarmasin, South Kalimantan Parameters observed; Growth Relative Weight, Length Relative Growth, FeedConversion, Survival. Aperture mouth, Out of Egg Yolk longtime, and parameterWater Quality For Supporting Data.From the data obtained during the study relative weight of the highest growthratein treatment B (87.78%), and the lowest was intreatment C (83.98%). The mean length of the highest relative growth in treatment A (30.56%), and the lowest was intreatment C (30.44%). The highest feed conversion intreatment B (1,55%), and thelowest was intreatment A (0,59%). The highest survival rate in treatment A (93.33%),followed bytreatment B (91.52%), andthe lowest was intreatment C(86.67%). Theaverage opening mouth highest in treatment A (58.849), followed involves the B(54.922), and the lowest was intreatment C (51.413). Long arowana depleted eggyolks from the eggs pots(TBK) to egg a big body (TBB) is 13 days, from TBB to swimegg (TBR) 15 days, and from plain eggs to TBR 14 days, so the totalis 42 days. Waterquality during the study ranged between temperature 30-32° C, pH73.77, salinity 0.10- 0.18 ppt, and ammonia from 0.13 - 0.18mg/l .Based on the analysis of variance (ANOVA) on all treatments only on survivaland feed conversion were significantly different, followed by HSD test for survivaland Duncan test for feed conversion. Judging from the data is the best overall treatment A with variations of mosquito larvae-bloodworms-mosquito larvae
ANALISIS TINGKAT PENCEMARAN POSFAT DAN NITRAT DI BEBERAPA SUB DAS KALIMANTAN SELATAN
Get PDFThis study aims to determine the pollution levels of nitrate (N) and phosphate (P) in South Kalimantan Several subzone based method Pollution Index (Kep_MENLH /115/2003). The results were obtained relationship (r) between the variables Quality Standards(Y1) and variable (X) or Phosphate and Nitrate = 0.792. Calculation of the value of R2-determinant obtained yield was 0.672. This means that 67.2% factor Water QualityStandard (Y) is influenced by factors Phosphate and Nitrate, while the remaining 33.8%is influenced by other variables that can not be explained in the equation. The ratio between the parameter P and N (P = 0.577 N = 0,062 = 9.30), is between 7 to 12. It means that the variable Phosphate and Nitrate is not a limiting factor for contamination.Calculation results of the pollution index pareameter P and N obtained a value of 9.30,still meet quality standards for some sub-sub-basins (Riam Kanan, Tabanio, Naiyan River, River Satui, Kintap River, and the River Sebamban)
PENDEKATAN METODE SEDIMENT DELIVERY RATIO UNTUK MENGETAHUI TINGKAT KEKRITISAN BEBERAPA SUB DAS DI KALIMANTAN SELATAN DALAM HUBUNGANNYA DENGAN KESESUAIAN PERIKANAN
Get PDFSediment Delivery Ratio Method approach is one method to determine the degree of criticality subzone. The purpose of this study was to determine the amount of erosion that occurs, the critical level of distribution and relationship levels of sediment load to the needs of fisheries in some subzone South Kalimantan.The results of water quality analysis of total suspended solids (TSS) showed thatthe rate of sedimentation (precipitation) is the highest in Sub-watershed area Kusan with arange of about 2918.22 tons / day and the lowest is subject subzone Pelaihari with a range of about 0.64 tons /day. Thus the content of TSS that do not affect the interests of fisheries are at subzone Pelaihari with TSS value of 16 mg/l
