Abstract

River is the most important things for the human life, one of the components environmental especially for whom whose living in the city and Ciliwung river is one of the major river beside of others 13 rivers. Bamboo trees, bananas, cotton, gempol and elo are the common flora were dominate plants along the riverbanks (gempol and elo taken from the local people words). Based from interview with some local citizens in the Ciliwung riverbank which pas through the district of Pangadegan (South Jakarta), Ficus racemosa L (elo tree) is the most important plant which can withstand river erosion and could maintained the riverbanks during flood and continued by taking sample that plant on that district for need of analysis and identification. From the calculation Gigantochloa apus types stake has the highest INP value to the over all plot of 65.43% while INP Ficus racemosa is still low, but Ficus racemosa can be one alternative plant for conservation in the Ciliwung river, because Ficus racemosa has strong roots. However the selection of other plants such as bamboo trees is more effective because it has fast growth. Therefore, by combining the types of plants that role as conservation may be a solution.

Abstract

The increasing human activity makes the preference for fast food increases. However, some people do not pay attention to the hygiene conditions of food processed from food stalls. Food handlers, equipment utilization, food processing, clean water, and the packaging are the critical points of bacterial contamination. Escherichia coli is a bacterium that usually used as the indicator of food hygiene. The objective of this study is to examine the contamination of coliform bacteria, especially E. coli at two hospital cafeteria by using MPN method and questionnaire regarding the implementation of the basic principles of hygiene. Stages of tests performed that are the presumption test, confirmation test, complementary test, gram stain test, biochemical test IMViC and supported by a questionnaire. From the two locations tested, some samples showed positive result in a presumption test and confirmation test but negatively complementary to biochemical test. This indicates that the sample does not contain E. coli bacteria in food, but there is the possibility of Citrobacter. The negative results of the IMVIC test showed that it is possible bacteria found in the presumption test and confirmation test not E. coli and non-pathogenic bacteria. Based on the results of the questionnaire, most of restaurant owner has understood to served food. Food at the hospital X and Y cafetaria are safe to consume because it has a negative E.coli.

Abstract

Excessive energi consumption play a role in increasing blood glucose levels (hyperglycemia), due to the inability of the hormone insulin to compensate the high blood glucose levels. Blood glucose receptor found in the hypothalamus of VMH (Ventro Medial Hypothalamus) and LH (the Lateral Hypothalamus) is able to detect and change the settings for the feeding activity. The aim of this study was to obtain the relationship between high sucrose feeding on male Wistar rats of behavior and activity. This method uses Wistar rats (Rattus norvegicus) as an animal model. Sixteen rats were grouped into 4 treatment groups. The first group was given additional feed 20% sucrose, the second group was given additional feed 40% sucrose, a third group was given additional feed 60% sucrose, and the last as a control group. This feed given continuously for 70 days.Observation of activities conducted using Opto-varimex® auto-track system ver.4.31. The results showed an corellation between activity based doses of sucrose.

Abstract

Penelitian ini dilakukan untuk mengetahui pengaruh Cu terhadap pertumbuhan kacang tanah (Arachis hypogaea L.) yang diinokulasikan dengan rhizobium. Distribusi Cu di organ tanaman juga dianalisa. Penelitian ini dilakukan dengan menggunakan Rancangan Acak Lengkap pola faktorial, masing masing kombinasi perlakuan dengan 6 ulangan. Faktor pertama yaitu konsentrasi /dosis CuSO4 yaitu aplikasi A0 : CuSO4 0 mg/3 kg tanah, A1 : CuSO4 60 mg/30 kg tanah, A2 : CuSO4 90 mg/30 kg tanah, A3 : CuSO4 120 mg/3 kg tanah. Faktor yang kedua yaitu B0 : tanpa inokulasi legin . B1: Inokulasi legin (10 g/kg benih) ,B2 :Inokulasi legin (20 g/kg benih). Parameter pengamatan antara lain kadar Cu pada organ tanaman (batang, akar dan daun), kadar Cu pada biji kacang tanah, berat bintil akar dan pertumbuhan tanaman kacang tanah. Data hasil pengamatan dan pengukuran akan dianalisis secara statistik menggunakan analisis sidik ragam (ANOVA) dan diuji lanjut dengan DMRT (Duncan Multiple Range Test) taraf kepercayaan 95 %. Hasil penelitian menunjukkan bahwa pemberian rhizobium yang dikombinasikan Cu memberi pengaruh yang nyata terhadap parameter pertumbuhan. Dalam jumlah sedikit (60 mg CuSO4/30 kg tanah) mampu meningkatkan pertumbuhan tanaman, tetapi dalam jumlah berlebih menurunkan pertumbuhan tanaman. Cu didistribusikan kesemua organ tanaman termasuk biji. inokulasi legin secara signifikan mengurangi pengaruh hambatan pertumbuhan dan mengabsorpsi kelebihan Cu.tingginya konsentrasi Cu di rhizosfer mengurangi jumlah nodul yang terbentuk. Hasil juga memperlihatkan akumulasi Cu di akar.

Abstract

This study aims to determine the most effective compound used to hydrolyze soy husk waste to produce reducing sugar as raw material for bioethanol fermentation. The study was conducted at the Laboratory of Bioprocess PPPTMGB "LEMIGAS" in April-September 2015. The method used is experiment using a randomized block design consisting of two factors. The first factor is the type of compounds used in the process of hydrolysis, namely H2SO4, HCl, NaOH, and NH3. The second factor is the concentration of hydrolyze compound 0.2%, 0.4%. 0.6%, 0.8%, and 1% (v/v) and every treatment repeated 4 times. Parameters measured were content of reduced sugar hydrolysis product, and secondary data that content of cellulose and hemicellulose also the density of ethanol. Concentration of reducing sugar from hydrolysis of soybean husk is analyzed by two-way ANOVA test. ANOVA analysis result indicate that the best hydrolysis compounds in hydrolizing soybean husk is HCl with the optimum concentration is 0,4%. And there are interactions between treatment of compound used to hydrolyze as well as concentration on reducing sugar concentration (mg/mL) as product from soybean husk waste hydrolysis. Post-hoc test showed that HCl 0,4% produce the highest concentration of reducing sugar at 31.23 mg/mL.
