Abstract

Enzim termostabil dari bakteri termofilik merupakan enzim yang sangat potensial untuk mengatasi kendala teknis industri yang berhubungan dengan proses pada suhu tinggi. Salah satu sumber enzim adalah mikroorganisme termofilik yang banyak terdapat pada sumber air panas. Indonesia merupakan negara kepulauan yang banyak mempunyai sumber air panas, salah satunya adalah Kabupaten Solok. Penelitian ini mencakup skrining dan identifikasi bakteri penghasil enzim termostabil selulase dan amilase dari sumber air panas Bukit Kili Ketek di Kabupaten Solok. Suhu air panas adalah 52°C pada bulan Juni 2009 dan pH air adalah 8. Kultur murni yang diperoleh adalah sebanyak 22 kultur Dari hasil pewarnaan gram, diperoleh sebagian besar bakteri air panas adalah jenis bakteri streptobacilli (basilus) gram positif, hanya dua isolat yang merupakan gram negatif yaitu isolat S1B dan S5B. S2A adalah isolat yang mempunyai aktifitas selulase paling tinggi dibandingkan dari isolat yang lain karena mempunyai indeks zona bening selulase lebih tinggi yaitu 2,6. Isolat S2A juga menghasilkan amilase tinggi dengan indeks zona bening 2,5. Persen identitas bakteri air panas S2A yang diperoleh adalah 97% dengan Anoxybacillus flavithermus strain AE3.

Abstract

This study  was conducted to determine the response of superovulation by giving 16 ml dosage  of FSH hormone to female Pesisir cattle.  The estrus schedule of 15 Pesisir cows was set by inserting CIDR (Controlled Internal Drug Release) into the vagina for 12 days. At day 10, all cattles were injected with FSH for three consequent days but with decreasing dosage. On the 3rd day, FSH injection was accompanied by PGF2α injection and CIDR was removed. The detection of estrus was performed at  day 13. Natural mating was proceeded after the estrus signs visible. Collection of donor embryos was done on the 6th and 8th day after mating. The variables  measured were the response of superovulation, total number of corpus luteum, number of embryos and sex ratio. The results obtained were all  Pesisir cows responded to superovulation. The  average number of of corpus luteum and embryoes per cow were  5.93±3.17 and -----, respectively,  while the total of transferable embryoes were 90, with an average of 6.00 or 61.64%. The sexing of embryoes obtained in this study from 146 embryoes awere 76.03% males (111 embryoes) and 23.97% females (35 embryoes). Based on total of transferable embryoes, there were 51.37% male embryos and 11.28% of females embryos. The result of this study showed that the sex ratio of male embryos was higher than female embryos.

Abstract

Background: Enteropathogenic Escherichia coli (EPEC) are pathogenic microorganisms causing inflammation and imbalanced gut microflora that may result in diarrhea. Pediococcus pentosaceus (P. pentosaceus) isolated from “dadih” (milk curd) are used as probiotics containing lactic acid bacteria (LAB), which are useful to improve the balance of intestinal microflora and inhibit the growth of pathogenic microorganisms. This study was aimed to recognize the effect of P. pentosaceus supplementation on stool frequency, tumor necrosis factor-α (TNF-α) and gut microflora balance in experimental mice with EPEC-induced diarrhea. Method: The study was conducted in 60 white mice (Mus muscullus) at Biomedical Laboratory, Biotechnology/Production and Animal Husbandry Technology Institute, University of Andalas, Padang in April 2012. The frequency of stool, TNF-α level and microflora balance of the mice were measured before and after the EPEC-induced diarrhea and following the administration of antibiotics. Statistical analysis was performed using ANOVA and Duncan test. Results: The highest mean stool frequency was found in positive control group, i.e. 55 times, which was reduced significantly after 12-hour P. pentosaceus supplementation in a dose of 2 x 108 cfu/g into 18 times. The mean TNF-α level in positive control group was 128.17 pg/mL that lowered significantly to 48.0 pg/mL. The highest mean total number of LAB was 97.0 x 107 cfu/g, which was significantly different from positive control group of 7 x 107 cfu/g. Conclusion: P. pentosaceus supplementation in a dose of 2 x 108 cfu/g may reduce the stool frequency, lower TNF-α and improve the gut microflora balance following 12-hour supplementation in diarrhea-induced mice. Keywords: Pediococcus pentosaceus, TNF-α, diarrhea, EPEC, gut microflora

Abstract

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

Abstract

DKI Jakarta Province consists of 5 cities and 1 district. At the north part of Jakarta there are beaches which became the estuary of 13 rivers and 2 canals. Ciliwung is the main river that has an effect on the lives of people in Jakarta. The Ciliwung river flows towards to BKB. Manggarai sluice gate is located at the upstream of BKB to control Ciliwung river flow. This study was conducted by giving two addition of Manggarai sluice gate, each dimension of additional gate is 3.4 m x 8.1 m and 5 m x 5.3 m. Discharge calculations for hydrology analysis used Log Pearson III while hydraulics analysis used software HECRAS 4.1.0. Discharge data at AWLR MT Haryono control point recorded on January 21st,2013 showed 287.876 m 3 /sec. From the data, sluice gate simulations conducted with 8 alternatives opening gates. In this study showed the most effective results for Q2th and Q5th with opening gates 2 m (alternative 4), Q10th with opening gates 4 m (alternative 5), Q20th and Q25th with opening gates 6 m (alternative 6), Q50 and Q100th with maximum gates opening (alternative 8).Keywords: Sluice Gate, Simulation, Gate Operation, Opening Gate

Abstract

Jragung irrigation Area is located in Demak Regency has decreasedin its performance. The result of existing analysis showed that there is an imbalance of irrigation water within it. Based on its performance analysis taken from regulation of the ministry of public works No. 32/PRT/M/2007, Jragung Irrigation area has been classified as poor and requiremore attention with 66.95% working performance only. Efforts to increase its performance is by rehabilitation priority scale with following the AHP (Analytical Hierarcy Process) methods. With its main priority is Jragung Dam and Main Canal of Jragung, subsequently Teluk Secondary Canal, Sugihwaras Secondary Canal, Jragung Secondary Canal, Karangsono Secondary Canal, Ngumpul Secondary Canal, Pamongan Secondary Canal and Panjen Secondary Canal respectively. Efforts to overcome the imbalance of irrigation water is by the alteration of cropping periods from November to December and conventional cropping methods to SRI (System Rice Intensification) methods could save 53.25 % of irrigation water. Keywords : Irrigation Performance, Water Balance, AHP, Priority Scale, SRI Method
