Abstract

This research is for finding the suitable synthetic daily rainfall generating model in the Middle Brantas River Basin - East Java. There are 7 models being considered, 4 single-site models, (1) the two-part, (2) the transition probability matrix, (3) the resampling, and (4) the time series, and 3 multisite models, (5) the conditional, (6) the extension of single site Markov chain, and (7) the random cascade. All time-series produced by the models are then tested statistically. The results show that the differences between the historial time series and the synthetical time series are not too significant. It turn out that the synthetic time series of multisite models are better than the synthetic time series of single-site models.Keywords: generating model, synthetic data, daily rainfall.

Abstract

ABSTRAK: Daerah Aliran Sungai (DAS) Jragung terletak pada Wilayah Kerja Balai Besar Wilayah Sungai Pemali Juana. Pertambahan penduduk di DAS Jragung wilayah hulu menyebabkan perubahan pada fungsi lahan. Studi Upaya Konservasi Lahan Berdasarkan Indikator Erosi dan Sedimen di DAS Jragung sangat diperlukan untuk meminimalkan permasalahan di DAS Jragung. Pendugaan laju erosi dan sedimentasi dihitung dengan model AVSWAT 2000. Hasilnya menunjukkan besarnya limpasan permukaan, erosi dan sedimentasi sebesar 707,519 mm/thn, 168,51 ton/ha/th dan 229.806,089 ton/th. DAS Jragung memiliki indeks bahaya erosi rendah sebesar 40,19%, sedang sebesar 25,66%, tinggi sebesar 14,63%, dan sangat tinggi sebesar 19,52% terhadap luas DAS jragung Upaya konservasi secara vegetatif dapat mereduksi erosi sebesar 38,19% dan secara mekanis dapat mereduksi sedimen sebesar 48,09%. Kata-kata kunci: Limpasan permukaan, erosi, sedimentasi, AVSWAT 2000 ABSTRACT: Jragung Watershed (DAS) located in BBWS Pemali Juana.

Abstract

Termostable enzyme from thermophilic bacteria is very potential to improve technical enzyme in industry which used hightemperature. High water temperature exerts selection pressure on microbial species leading to specific flora that survivesand tolerates heat stress. The relative isolation and unique physical properties of Bukit Kili Ketek Hot Springs in Solok,West Sumatera may yield unique thermophiles. The generation of extracellular enzymatic bacterial is highly desirable forproduction of hydrolitic enzymes, which are useful in various industrial application and in animal feeds. This study,conducted to purify extracellular enzymes from thermophilic bacteria (Anoxybacillus sp.). This bacteria was isolated inBukit Kili Ketek Hot Springs, and after identified by analysis of 16S rRNA gene, 97% of similiarty with Anoxybacillus sp.was of obtained. The temperature of the hot waters was 52°C and the pH was 8. Extracellular and hydrolytic enzymeproduction were screened by qualitative SDS-PAGE method. SDS-PAGE analysis gave protein bands at ±110 kDa, ±80 kDa,±60 kDa, 50 kDa, 25 kDa, and ±10 kDa, respectively. Extracellular enzymes were used to degrade cellulose waste. Thecellulose activity for degradation of baggasse and pineapple pulp was 0,451 IU/mL and 0,310 IU/mL at 50°C and pH 6.

Abstract

Background Enteropathogenic Escherichia coli (EPEC) is a causative agent of intestinal inflammation and microfloral imbalance, leading to diarrhea. The presence of tumor necrosis factor-α (TNF-α) in the feces is an indicator of inflammation in the intestinal mucosa. Dadih, (local made of fermented buffalo milk), contains probiotics and is widely consumed by the people in West Sumatera, Indonesia. Weisella paramesenteroides, a probiotic lactic acid bacteria (LAB), has been isolated from dadih and is believed to be useful for improving intestinal microflora balance and inhibiting the activity of harmful microbes. Objective To determine the efficacy of W. paramesenteroides administration in various doses and durations on bowel frequency, stool’s TNF-α levels, and intestinal microflora balance on mice with EPEC-induced diarrhea. Method This randomized experimental animal study examined two factors relating to the effects of W. paramesenteroides on EPEC-induced diarrhea, namely doses of probiotics (factor A), and durations of observation (factor B). The subjects consisted of 100 male white mice (Mus musculus) aged 8 weeks, with weights of 25-30 grams. The outcomes measured were bowel frequency, stool’s TNF-α levels, and the balance of intestinal microflora on mice with EPEC-induced diarrhea. Subjects were divided into 5 groups: the negative control group (received neither EPEC nor probiotic), positive control group (received only EPEC), and three experimental groups (received EPEC and different doses of W. paramesenteroides ). Probiotics were given twice at the 12-hours and 24-hours for the experimental groups, while the durations of observation conssited of baseline, 12 hours, 24 hours, and 36 hours. Results After 36 hours, subjects with EPEC-induced diarrhea who received W. Paramesenteroides administration in doses of 2 x 108 (A3), were found to have the largest decline of mean defecation (a 4.4-fold decline) and the largest decline of stool’s mean TNF-α levels (48.3 pg/mL), compared to the positive control group, and other experimental groups who received higher doses of probiotics.
