Judul: Analisis kebutuhan air tanaman jarak pagar dengan menggunakan program CWP (Crop Water Balance) sebagai aplikasi teknologi di perkebunan Condong-Garut, Jawa Barat
Abstrak: Siklus hidrologi atau siklus air merupakan proses pergerakan air dalam segala fasenya di atrnosfer, litosfer dan hidrosfer. Air merupakan kebutuhan mutlak suatu tanaman dalam jumlah cukup dan pada saat yang tepat. Kehilangan air melalui evaporasi tanah dan transpirasi tanarnan disebut evapotranspirasi, dimana evapotranspirasi ini merupakan saIah satu komponen neraca air.

Abstrak: Water balance is the balance of the input and output of water somewhere at a certain period, so it can be to determine the amount of the excess or shortage of water. This study aimed to analyze the flow of water and the excess water needs that occur at BBPTP. The procedure consisted of field studies, literature review and data analysis. Based on the analysis, the direction of water flow in the area around the research flowing to the south where there is a Cijengkol river downstream water flow. Based on the analysis of the water needs of the consolidation that has been done can be concluded highest evapotranspiration values occurred in October that is 7.13 mm/day. The highest value of water demand in October is 2.10 lt/sec/ha. The maximum irrigation discharge occurs in the irrigation channel number 7 is 28.01 lt/sec with 13.34 ha area. Based on the analysis of rainfall can be summed value maximum daily rainfall for the area of research at the Center for Rice Research amounted to 76.25 mm with a return period of 2 years and Gumbel distribution. The maximum effluent discharge occurs in the drainage channel number 88 is 117.30 lt / sec with 14.15 ha area.

Judul: Peptides Hydrolysate Derived from Collagen of Snakehead Murrel (Channa striata) Skin Demonstrate Anti-oxidant and Anti-cholesterol Activities.
Abstrak: Anti-cholesterol and anti-oxidant play crucial role to combat cardiovascular disease (CVD) related to formation of arterial plagues from oxidation of cholesterol. In the past decades, research on bioactive peptides demonstrating anti-cholesterol and anti-oxidant activities have been reported as the alternative drugs. In this study, acid soluble collagen was extracted from the skin of snakehead murrel and employed to induce production of collagenase by Bacillus licheniformis F11.4. The collagenases secreted were in turn purified through AKTA Purifier (ion exchange, DEAE column) and used to produce peptides hydrolysate. The purified enzymes were grouped in two distinct collagenase fractions, designated as fraction D and F. Peptides hydrolysate produced by the fraction D was found to demonstrate HMG-CoA inhibitor activity comparable to pravastatin and limited anti-oxidant activity. Meanwhile, peptides hydrolysate generated using the fraction F demonstrated anti-oxidant activity comparable to BHT (2mM), vitamin C (2mM) and vitamin E (2mM), but limited HMG-CoA activity. Combination of the fraction D and F resulted in substantial HMG-CoA inhibition and anti-oxidant activities.
