Abstract: The flower characteristics of a plant is one of the important traits correlated to its productivity. Study on flower characteristics is useful to understand how to increase the crop productivity. The research was conducted at Agro Techno Park Center, Indonesian State Ministry of Research and Technology, Bakung Village, Ogan Ilir Distric South Sumatra from April 2007 to August 2008. The objective of this research was to evaluate the flower characteristics and the yield of jatropha (Jatropha curcas L.) accessions. The research was arranged in a randomized block design, consisted of fifteen accessions of jatropha, with three replicates. The Jatropha accessions were collected from different agro ecosystems located in Sumatra, Java, and Borneo. The results indicated that the evaluated accessions have significant differences in the flower characteristic and the yields. The ratio male–female flower is the most important character for J. curcas L. because it has a significant correlation to the yield.

Abstract: The research was conducted to measure rural banks (BPR) efficiency level in Jabodetabek and also to identify factors that increase the efficiency level. The measurement was done using non parametric approach with Data Envelopment Analysis. The result indicated that rural banks in Jabodetabek area were in inefficient condition, 80% of rural banks observed were inefficient both in technical and scale. Measurement on several asset distribution showed rural banks had efficiency scale on certain business scale, rural banks with total asset between Rp.1 – Rp.10 billion had the highest efficiency scale and rural banks with total asset less than Rp.500 million had the lowest efficiency scale. Potential improvement analysis result with CCR and BCC models showed that other income was the most contributed output variable to increase 30% to 40 % of rural banks efficiency level. Meanwhile, measurement using BCC model showed that, from output side, current asset has contributed to increased rural banks efficiency level by raising revenue from current asset management up to 10% from average value in 2007. On input side, all input variable had the same potential improvement value which increased the efficiency level by reducing labor cost, fixed asset cost, and the cost of fund 17%-18% from average value in 2007.

Abstract: This study uses regression analysis with a log model to analyze the effect of government spending, foreign reserves and the money multiplier on the money supply in Indonesia for the period before the economic crisis (1990-1997), since the crisis (1997-1999) and overall (1990-1999). Before the crisis, the results show that government spending is significantly and positively related to the money supply; foreign reserves are not significant, and the money multiplier is actually significantly and negatively related to the money supply. Since the crisis, government spending is still positively and significantly related with money supply while the foreign reserves and money multiplier are not significant. For the entire time period, government spending and foreign reserves have a positive and significant effect on money supply while the money multiplier has no significant effect. The government should apply fiscal policy as is has since the crisis and increase the amount of foreign reserves which it holds. The government should not depend on using the money multiplier in monetary policy since it was found to have no significant effect on money supply. Abstract in Bahasa Indonesia : Penelitian ini menggunakan analisa regresi dengan model log untuk menganalisa pengaruh pengeluaran pemerintah, cadangan devisa, serta angka pengganda uang (money multiplier) terhadap jumlah uang beredar di Indonesia untuk periode periode sebelum krisis (1990-1997), sesudah krisis (1997-1999) dan secara keseluruhan (1990-1999). Sebelum krisis hasil menunjukkan bahwa pengeluaran pemerintah secara signifikan berpengaruh positif terhadap jumlah uang beredar (M2); cadangan devisa tidak signifikan terhadap jumlah uang beredar; sedangkan angka pengganda uang berpengaruh negatif dan signifikan terhadap jumlah uang beredar. Sesudah krisis, pengeluaran pemerintah secara signifikan berpengaruh positif terhadap jumlah uang beredar sedangkan cadangan devisa dan money multiplier tidak signifikan. Untuk seluruh waktu analisa, pengeluaran pemerintah dan cadangan devisa berpengaruh secara signifikan dan positif terhadap jumlah uang beredar sedangkan angka pengganda uang tidak signifikan. Pemerintah diharapkan menerapkan kebijakan fiskal sesuai yang telah diterapkan selama krisis berlangsung serta meningkatkan jumlah cadangan devisa yang dimilikinya. Pemerintah sebaiknya tidak mengandalkan money multiplier dalam kebijakan uang yang beredar karena tidak berpengaruh signifikan terhadap uang yang beredar. Kata kunci: kebijakan moneter, pengeluran pemerintah, cadangan devisa, angka pengganda uang, model

Abstract: Hernawati H, Wiyono S, Santoso S (2011) Leaf endophytic fungi of chili (Capsicum annuum) and their role in the protection against Aphis gossypii (Homoptera: Aphididae). Biodiversitas 12: 187-191. The objectives of the research were to study the diversity of leaf endophytic fungi of chili, and investigate its potency in protecting host plants against Aphis gossypii Glov. Endophytic fungi were isolated from chili leaves with two categories: aphid infested plants and aphid-free plants, collected from farmer’s field in Bogor, West Java. Abundance of each fungal species from leave samples was determined by calculating frequency of isolation. The isolated fungi were tested on population growth of A. gossypii. The fungal isolates showed suppressing effect in population growth test, was further tested on biology attributes i.e. life cycle, fecundity and body length. Five species of leaf endophytic fungi of chili were found i.e. Aspergillus flavus, Nigrospora sp., Coniothyrium sp., and SH1 (sterile hypha 1), SH2 (sterile hypha 2). Eventhough the number of endophytic fungi species in aphid-free and aphid-infested plant was same, the abundance of each species was different. Nigrospora sp., sterile hyphae 1 and sterile hyphae 2 was more abundant in aphid-free plants, but there was no difference in dominance of Aspergillus flavus and Coniothyrium sp. Nigrospora sp., SH1 and SH2 treatment reduced significantly fecundity of A. gossypii. Only SH2 treatment significantly prolonged life cycle and suppress body length, therefore the fungus had the strongest suppressing effect on population growth among fungi tested. The abundance and dominance of endophytic fungal species has relation with the infestation of A. gossypii in the field.

Abstract: In previous studies, Zingiber officinale, Piper retrofractum, and the combination showed cytotoxic activity, induced apoptosis, and p53 expression of HeLa, T47D, and MCF-7 cell lines. This study was conducted to investigate the cytotoxic and apoptotic activity of Zingiber officinale (ZO), Piper retrofractum (PR), and the combination as well as their effect to p53 expression on Myeloma and WiDr cells. The powder of ZO, PR, and ZO + PR combination (1:1) were macerated with 96% ethanol for 3 x 24 hours. MTT cytotoxic assay was performed on Myeloma and WiDr cell lines. Apoptotic cells were stained with ethidium bromide and acridine orange. Imunohistochemical expression of p53 was examined on Myeloma and WiDr cell lines. Doxorubicin was used as positive control in all assays. Results showed that ZO, PR, and ZO + PR combination had cytotoxic activity on Myeloma cells with IC50 of 28, 36, and 55 mg/ml respectively and WiDr cell lines with IC50 of 74, 158, and 64 mg/ml respectively, induced apoptotic activity, and increased p53 expression on Myeloma and WiDr cells. These results suggest that ZO, PR, and their combination induced Myeloma and WiDr cells in apoptosis through p53 expression.

Abstract: Red pepper farmers as the farm managers deal with risk management. Objectives of this study was to analysis farmers’ behavior in coping with risks and risks management strategy on red pepper farm management on lowland in Central Java. This study was carried out between February to March, 2009, in lowland areas in Kersana sub district, Brebes district; Karangnongko, Jogonalan, Manisrenggo, and Ngawen sub districts, Klaten district, and Teras sub district, Boyolali district, Central Java. Decision to adopt dominant cropping pattern by including red pepper as high economic value commodity was an ex ante risk management strategy. Meanwhile, interactive risk management was carried out through over use of seeds and pesticides. If the farms failed and led to lower households’ incomes and farm sustainability, the farmers tended to employ other farm incomes, to draw savings, to sell some assets, and to borrow as the ex post risk strategy management. Implications of this study are: (i) cropping patterns need to include red pepper to sustain and to improve farmers’ incomes; (ii) application of hybrid red pepper varieties to cope with environmental pressure and pests’ attack; (iii) farm practice technique should be locally specific based on red pepper varieties and agro ecology; (iv) farm diversification and agriculture insurance could lessen production risk; and (v) farmers’ group and contract farming will reduce marketing risks.

Journal of Coastal Development , 2009,
Abstract: Most of coastal regions in Indonesia have experienced water scarcity where water resources are becoming more and more threatened due to the rapid growth of population, aquaculture industries and agricultures. Brackish water reverse osmosis (BWRO) desalination may be used to overcome the supply potable water problem in the coastal regions. Brackish water having total dissolved solids (TDS) content in the range of 1,000–10,000 ppm can be desalinated at a reasonable cost. This work was aimed to find valuable technical data for plant design and operation. Cost analysis also was conducted to obtain specific water cost. The results show that stable system performance was achieved. Based on a case study of small scale BWRO with capacity of 50 m3/day, specific water cost was around of IDR 6,100/ m3.

Abstract: The purpose of this study was to evaluate a credit risk control system to implement risk-based audit (RBA). The case was conducted in three stages using system approach. The first stage was to identify the factors influencing the effectiveness RBA implementation. Identification process was conducted through gap observation and exploration to determine key factors derived through gap analysis comparing the empirical outcome of the effectiveness credit management process from the expectation outcome. The second stage was using Exponential Comparison Method (ECM) which produces the ranking and the priority of the key factors through experts with in-depth interview which is the paramount importance steps to evaluate. The third stage was using Analytical Hierarchy Process (AHP) techniques, involving the experts with questionnaire and in-depth interview to decide the best, suitable alternative strategies to cope with the negative gap, to reach the goals expected which is to minimize the gap. There were four components mentioned to complete and to detect the gap, which credit operation, human resource knowledge, organization, and supporting system/IT. The output of this study was a credit risk control system for the bank. The study has limitation, due to the scope of the region of the bank, and the risk mapping only for credit risk. The preposition of the study, that the application of the system will enhance the implementation of risk-based audit model.
