Valuasi Ekonomi Mitigasi Lahan Pertanian Rawan Banjir

: The purpose of this study is to identify the location of flood prone areas, determine the economic value of agricultural land prone to flooding mitigation, and determine the factors that influence the Willingness To Pay (WTP) mitigation of flood-prone farmland in Pur­worejo.The data used is primary data is done by direct interview to the respondents. The sampling technique by using simple random sampling. The sample in this study were 81 farmers in the village Kedungmulyo. Analysis of data using Geographic Information Systems (GIS), Contingent Valuation Method (CVM) and multiple linear regression. The results of this study indicate that almost all districts in the flood-prone Purworejo except District of Bruno and the District Kaligesing. The average willingness to pay for mitigation of flood-prone agri­cultural land between Rp51.000-Rp 100.000.The level of farmer losses average about 0-35% of normal production, and a decrease in average production of about Rp0 - Rp1 million of normal production. The results of multiple linear regression analysis showed that the variables of education, occupation, number of dependents, land prices and land area affect the willing­ness to pay or Willingness To Pay (WTP) mitigation of agricultural land prone to flooding in Purworejo

Integrated Community Development in Rural Border Region (Case Studi in Tanjung Hulu Village, Nunukan, North Kalimantan)

Tanjung Hulu is a village in Lumbis, a district in Nunukan area, North Kalimantan Province. The village is included as one of villages located in the border area of Indonesia, bordering directly Malaysia. Based on geography, demography and social phenomena that are growing and developing in the community, three main problems were found in the area. There are economic problems and poverty, low quality of educational and poor public health quality. The CEGs (Community Engagement Grants) programs that have been applied are the economic development programs to increase the productivity of society based on the primacy of human resources and local natural resources, educational programs to improve school facilities and learning methods, and public health programs to improve the general health of the community. There were five methods used to approach the community and solving the problems, which are assessment, group discussion, problem-solving, advocacy, and recommendations. The results are constructed filial primary school, classroom facilities repair, Taman Baca improvement, PHBS enhancement for children and family, nationality enhancement for students, increasing skills of women community (PKK), and joining hands with Posyandu to provide health services to the community.     Keywords: community, economic, educational program, public healt

Solation and Characterization of a Novel Benzoate- Utilizing Serratia Marcescens

A new benzoate-utilizing strain, Serratia marcescens DS-8, isolated from the environment was characterized. The strain was enterobacilli, Gram negative, mesophilic, non halophilic, and aerobic bacterium that showed motile ovale-rod shaped cells. The isolate produced extracellular chitinase, protease, and prodigiosin (a red pigment produced by several Serratia strains yielding bright red or pink colonies). A physiological assay using Microbact* test showed that the strain was closely related to Klebsiella ozaenae (49.85%) and Serratia liquefaciens (24.42%), respectively. However, 16S rRNA sequence analysis indicated that the strain was closely related to S. marcescens DSM 30121 with similarity level of 98%. DS-8 strain was able to synthesize its own vitamins. Optimum growth in benzoate was obtained at pH between 7-8.5 and NaCl concentration of 1-1.5% (w/v). The isolate could grow in benzoate-containing medium up to 10 mM. Other carbon sources that could support the growth of DS-8 were casamino acid, glutamate, glucose, acetate, potato starch, and ethanol

Uji Potensi Bakteri Kitinolitik dalam Menghambat Pertumbuhan Rhizoctonia Solani Penyebab Rebah Kecambah pada Kentang Varietas Granola

A study on assay the potential of chitinolytic bacterial isolates to inhibit the growth of Rhizoctonia solani causal agent of damping-off on potato was carried out in Laboratory of Observation Pest and Disease, Medan Johor, UPT. Protection of Crops and Holticulture 1 and Laboratory of Microbiology, Department of Biology, Faculty of Mathematics and Natural Science of Universitas Sumatera Utara, Medan. Two out of six isolates of chitinolytic bacteria showed capabilities to inhibit of R. solani growth. The most effective isolates to inhibit the growth of R. solani were Enterobacter sp. BK15 and Bacillus sp. BK13, that were able with inhibition zone of 2.05 and 2.35 cm, respectively. These two isolates also showed to be able to reduce fungal infection by 31.25% and 37.5%, respectively

Analisis Finansial USAha Keramba Jaring Apung di Perusahaan Perseorangan Dobro

This research is intended to know factors influencing fish production, financial performance and business security of private company Dobro. Data which are analyzed including production data (production, feed, seed and worker) for fish production factors analysis, balancing and profit/loss statement 2006 - 2009 for financial performance and business security analysis. The production factors analysis in this research uses regression method with Cobb-Douglas production function approach. The financial performance and business security use financial statement comparison and ratio analysis. Ratios that be researched are liquidity (ratios that be researched are current and quick ratio), solvability (ratios that be researched are total debt to total asset ratio and total debt to equity ratio), efficiency (ratios that be researched are inventory turnover, account receivable turnover, fixed asset turnover and total asset turnover) and profitability ratio (ratios that be researched are gross profit margin, operating profit margin, net profit margin and return on investment). Business security analysis use Altman Z” score to detect company position in Altman area of bankruptcy. The result of this research could be concluded that fish production is simultaneous and individually influenced by feed, seed and worker. Financial analysis shows company liquidity in good condition with positive average growth values. Solvability is also in good condition with negative average growth values. Commonly efficiency and profitability have normal values, but have negative average growth value. Based Altman Z” score, company exists in area which secure from bankruptcy threat

Mathematical Modeling of SEIR Type to Controlling Diabetes Mellitus Disease Using Insulin

In this research the developed model is SEIR type mathematical modeling using insulin as a form of treatment. SEIR is abbreviation of susceptible (S), exposed (E), infected (I) and recovered (R). Expected goals include to making mathematical models for spread of diabetes mellitus, fixed point determination and basic reproduction number, stability analysis of fixed point, simulation of fixed point stability, simulation of population behavior to know the strategy of controlling diabetes mellitus. Analytical and numerical analysis results were obtained two fixed points, namely the point of no disease (disease-free equilibrium) and the point of disease (endemic equilibrium). Stability analysis of each fixed point indicates that the fixed point there is no stable disease when R0 < 1, whereas the fixed point there is stable disease when R0 > 1. Numerical simulations show that, with reduced Susceptible population contact rate with the exposed population causing  to decrease, so the spread of the disease does not appear in the population. These results indicate that one strategy of controlling the spread of diabetes mellitus can be done by reducing the rate of contact susceptible population with eksposed. &nbsp
