Abstract

A research was conducted in order to investigate the effects of supplementing methionineand lysine as carnitin precursor in feed on the performances and fat contain of broiler chickens.Completely randomized design, 4 treatments and 4 replications (total 32 male chickens) wasutilized in the experiment. Control feed (meet NRC recommendation) and water were provided adlib during experiment (43-days). Treatments used in the experiment started at 22-days of age wereR0 (Control Feed), R1 (Control Feed + carnitin precursor type A (L-HCl Lysin 0,50 % + DLMethionine0,57 %)), R2 (Control Feed + carnitin precursor B (L-HCl Lysine 2 % + DLMethionine0,57 %)), and R3 (Control Feed + carnitin precursor C (L-HCl Lysin 1,50 % + DLMethionine0,19 %)). Data were gathered as parameters including body weight, growth rate, feedconsumption, feed conversion, carcass percentage, abdominal fat, and cholesterol contain. Datawas analyzed used ANOVA, then DMRT. Results show that supplementing methionine andlysine as karnitin precursor in feed affected increasing body weight and growth rate, decreasingfeed consumption, abdominal fat and cholesterol contain, but it did not affect feed conversion andcarcass yield. Based on results, the treatment R2 carnitin precursor B can be recommended as bestchoice feed for reducing abdominal fat and cholesterol contain but still produce high carcass yieldand feed efficiency.

Abstract

Peat land has high potency to develop as agriculture land. It is widely distribute in Kalimantan, Sumatera, Sulawesi and Irian Jaya.  One of constrains in peat land is low in fertility due to low of soil quality. Soil quality of peat land depends on peat decomposition rate and depth of peat. Soil macrofauna has a role in decomposition, carbon cycle, nutrient redistribution and soil aggregation. To become bioindicator of soil quality, soil macrofauna should have some characteristics such as specific response, sensitive to conditional change and abundantly found. The study conducted on distinct land use in Basarang and Kalampang, Central Kalimantan. Samples of soil macrofauna collected by using hand sortir and pit fall trap methods on rainy season and dry season in 2004.  Result of the study  showed that different of land use correlated to population and diversity of soil macrofauna. Diversity of epigeic macrofauna significantly correlated with C-organic and C/N ratio, while diversity of endogeic macrofauna correlated to pH, C-organic and soil water content. Earthworm, ant, and millipida are soil macrofauna that have a potency as bioindicator of peat soil.

Abstract

A good urban structure and activity need a green spaces to increase its ecological function. However, trees will not fully be able to fill an important space in urban areas while the shrub woody vegetation has the potential to fill that space. Therefore, the aim of this study is to determine the  potential of shrub as a constituent of urban vegetation so it can be used as material information about the planning of land use in the district of Cempaka. This sudy was conducted by determining the three sampling stations and 3 plots of 4m x 4m in wide on each station with data based on a map of shrub green space in District of Cempaka using purposive sampling method, the analysis performed includes the analysis of shrub canopy, measured environmental parameters, and data were analyzed with analysis of canopy volume, Pearson correlation analysis and analysis of Importance Value Index (IVI). Shrub vegetation estimation results indicate that the shrub canopy volume in the district of Cempaka is up to 22,462,878.50 m3 in the bush land area of 5675.116 hectares. Pearson correlation analysis showed that the shrub canopy volume in the district Cempaka effect on changes in environmental factors. Besides the most dominant species is Ficus fistulosa Reinw. ex Bl with IVI of 56.1%.

Abstract

Penelitian bertujuan mengetahui pengaruh pemberian doksisiklin secara oral pada induk mencit bunting pada masa organogenesis terhadap gambaran histologi kartilago epifisialis femur fetus. Digunakan 40 mencit betina galur DDY yang belum pernah bunting, memiliki siklus estrus teratur, berat badan 25 g yang dikelompokkan menjadi 4 kelompok secara acak. Kelompok I (kontrol) diberi 0,5 ml akuades, berturut-turut kelompok II, III, dan IV diberi doksisiklin dosis 26, 52, dan 104 mg/kg bb/hari. Pemberian dilakukan secara oral mulai kebuntingan hari ke 6 sampai hari ke 15 (masa organogenesis). Pengamatan dilakukan pada kebuntingan hari ke 18 dengan bedah sesar untuk mengambil fetus dari uterus. Preparat kartilago epifisialis femur fetus dibuat dengan metode paraffin dan pewarnaan Hematoksilin-Eosin. Tebal lapisan kondrosit dalam setiap zona kartilago epifisialis femur fetus dianalisis dengan Anova dan dilanjutkan uji DMRT. Data kerusakan kondrosit pada jaringan kartilago epifisialis femur fetus mencit dianalisis secara deskriptif. Ditemukan bahwa doksisiklin 104 mg/kg bb/hari menyebabkan perubahan lapisan kondrosit pada zona proliferasi, yaitu letak kondrosit saling berjauhan, tersusun tdak beraturan dalam masing-masing lajur, dan tidak membentuk deretan kumpulan sel yang sejajar dengan sumbu panjang tulang. Doksisiklin juga menyebabkan menipisnya zona proliferasi, zona maturasi dan zona kartilago yang mengalami mineralisasi seiring dengan meningkatnya dosis.

Abstract

Heavy metals found in water bodies will accumulate in sediments and bodies of aquatic biota both diffusion and through the food chain. This study was conducted to determine the bioaccumulation of heavy metals lead and cadmium in the organs of mudskipper P. schlosseri and B. boddarti, water, sediment, and small mangrove crabs as a food supplement. The collection was carried out in the Kuala Tambangan village by means of a purposive sample. The process of analysis of heavy metals is carried out on the gills, skin, liver, kidneys and embalmed meat. Surgical implants were analyzed using the ASS method. The first test results were the highest Pb metal 12.49 mg / kg and Cd 5.30 mg / kg in the kidney of P. schlosseri. The results of the analysis on the kidneys of B. boddarti species contained the highest Pb content of 7.56 mg / kg and Cd 3.94 mg / kg. The second test results of analysis of the content of heavy metals Pb and Cd in undetectable tympanic organs that is <0.24 mg / kg for all organs measured. The testing of the three Pb and Cd metal contents was partially undetectable, some containing heavy metals but still below the quality standard, except that the content of Cd in the liver of P. Schlosseri ie 0.364 mg / kg had exceeded the normal threshold. Pb metal content in tide water reaches 0.07 ml / l and passes the quality standard, while the Pb and Cd content in sediment and mangrove crabs as food chain is still below the standard and some heavy metals are not detected.
