Early detection and identification of soybean diseases is important to support better productivity of soybean. The demand for the availability of an expert on soybean disease is very high, especially for the beginners in the field of agriculture. However, the number and time allocation of the experts are not adequate to serve farmers located in different geographical areas. Therefore, an expert system is proposed as a solution to use as a diagnostic tool for soybean diseases just like a human expert. It will be even easier when the system is implemented into an Android-based application to be used anywhere and anytime. The objective of this study was to analyze and design an expert system for early identification of soybean diseases. This study was adopting the Expert System Development Life Cycle (ESDLC) approach. The stages were project initialization, knowledge engineering process, and implementation. The study was started with the project initialization phase that conducted in September 2014 and the completion of the implementationphase in August 2015. The results of research were in the form of document analysis and prototype system.

Major constraints and problems associated with postharvest handling of fresh banana are short shelf life and lack of proper postharvest handling. The purpose of this study was to evaluate fruit quality and shelf life under MAP packaging, with or without KMnO4. This research was conducted between May-August 2013 at the laboratory of food processing and agricultural product, Bogor Agricultural Institute. The data obtained were analyzed with analysis of variance (ANOVA), if the results were significant at 5%, then further test was carried out with Duncan test. The results indicated that the shelf life of bananas packaged in White Stretch Film (WSF) with KMnO4 (MAP active) at 28Â°C could be stored for 10 days and comparable to 6 days without KMnO4 (MAP passive), and the shelf life of fruit packed in MAP active at 15Â°C could be stored for 24 days and comparable to 16 days for MAP passive. The 3 factors interaction were significant at different levels of starch content at 6th day, whereas total soluble solids (TSS) was significantly different at 2nd day of storage. MAP active treatment could delay starch content degradation and TSS when compared to passive MAP.

Changes in the frequency and severity of extreme climate events and in the variability of weather patterns will have significant consequences for stability of agricultural system. Research objectives were to a) analyze the Impact of Climate Change on Food Crops in Dryland b) develop a software prototype analysis of the impact of climate change on food production, especially upland rice and maize on dry land; c) create a simulation with multiple scenarios of the impact of climate change on dry land. The study was conducted in South Sulawesi, West Nusatenggara and East Nusatenggara.The activities were carried out by projecting precipitation using scenarios: a) SRESA2 (Scenarios of climate change by assuming economic growth is lower and population growth remains high so the rate of greenhouse gas emissions increased, b) SRESB1 (scenario of climate change by assuming mitigation efforts through expanding efficient use of energy and technology improvements so that the emission levels are lower) and making projections of production of upland rice and maize using Decission Support System for Agrotechnology Transfer (DSSAT) as resource information in the preparation of prototype software information Systems Climate Change Impacts on Crop Production (SIDaPi TaPa). The system was built based on the analysis simulation model projections of production output DSSAT. Based on SRES scenarios A2, the decline in rainfall increased until 2050 in several districts, in South Sulawesi, West Nusatenggara and East Nusatenggara.Treatment of adaptation through SRESB1 scenarios could be effective to anticipate a decrease in rainfall in some regions, either in 2025 or 2050. In general, the region experiencing a decrease in rainfall will also decrease in production of both upland rice and maize production. The decline in upland rice production by SRESA2 scenario until 2050 was between 20-25%, and by a scenario adaptation SRESB1 the decline in production could be minimized to only between 7 -10%.The decline in maize production in the plot until 2050 by SRESA2 was between 9-15%, using scenarios to reduce production SRESB1 was only 5-8%. SIDAPI TAPA is a software analysis of the impact of climate change on food production, especially upland rice and maize on dry land in South Sulawesi, West Nusatenggara and East Nusatenggara.

Capacity of extension agents in understanding climate forecasting and climate change is allegedly limited. Therefore, it is necessary to improve their capacity on this issue. Research was conducted between May to December 2014. Indramayu in West Java was choosen purposively, representing irrigated-land agroecosystem. Respondents were extension agents selected from Agricultural Extension of Fisheries and Forestry Services (BP3K) or Agricultural Extension Services (BPP)with their working area being considered high vulnerability to climate change. Total respondents were 59 extension agents randomly selected. There were three phases of dynamic hypothesis resulting in : 1) problem identification, 2) ideal capacity determination; and 3) model design. Methods of data collection were survey, interview, and focus group discussion (FGD). A RAP-FISH ordination technique through Multi Dimensional Scaling (MDS) was used to assess the existing extension capacity and identify sensitive attributes influencing the ability of the extension agents in the use of climate information through analysis of leverage in each variable. Results showed that accessibility to resources, information management and election of extension dimension methods were the dimensions to be considered for improving the extension agents capacity building in climate utilization. Therefore, a structural approach should be done through increased synergy between institutions involved in capacity building of extension agents and its resources. Moreover, synergy amongst sources of information should be conducted to encourage the roles of BP4K and BP3K in managing climate information. While the functional approach is done through re-designing capacity development activities on utilizing climate information, with the focus on improving the accessibility, information management, and selection of extension methods.

White corn is a source of functional food, particularly in dry land and dry climate environments. Indonesian Agency for Agricultural Research and Development (IAARD) has released six white corn varieties with various characteristics with wide adaptation area. Breeding programs for developing high yielding white maize varieties is conducted by a series of steps including evaluation of agronomic characteristics of lines/varieties. The objective of the research was to test the applicability of step wise regression model to determine/select agronomic variables that significantly contributed to the yield of white corn. Research was conducted in rainy season 2012 at Muneng experimental station, East Java Province. Maize parental plants used were the result of crossing CML140 x CML264Q lines namely Bima Putih. A total of 14 variables were tested for their significances to maize yield. SPSS and Microstat software were used to calculate the best variables that contributed to the yield significantly. The results showed that among 14 variables involved in the calculation, there were five variables that contributed to the yield, namely: weight of cob at harvest (x5), ratio of the weight of dry grain to the total cob weight (x9), the seed moisture content (x6), and number of ears (x4). Regression models generated from step wise screening was y=-4,33+0,763x5+0,1009x11+0,104x9-1,22x6+0,016x4. The coefficient of determination (R2 ) of the model was 0.99, indicating the ability of the regression model to fit the data. This showed that the five independent variables included in the model were the main variables in determining the outcome of hybrid seed Bima Putih-1. This result could be further used as reference to conduct parameter screening to produce high yielding white maize

Land rent of paddy field is lower than oil palm and it encourages farmers to convert wetland to oil palm plantations.This study aimed to determine the impact of land use on the welfare of rice farmers. The experiment was conducted in Kampar district from April to December 2013. Data were collected through a field survey of 30 rice farmers and 30 farmers who converted wetland to oil palm plantations. Land rent value of paddy rice farming management was then compared with the land rent of oil palm plantations. The alignment of the calculation of land rent value of both commodities was carried out by PVNR value approach to timing analysis for 25 years (according to the economic lives of oil palm plantations) and a discount rate of 10%. The economic analysis showed that the average rice farming land rent value was Rp.9.834.727/hectare/year. The average land rent value of oil palm was Rp 16.255.090/hectare/year. PVNR - land rent value of the rice farming was Rp. 89.200.977 / hectare, while the value of farm land rent - PVNR of oil palm was Rp. 111.388.769/hectare . PVNR - land rent of oil palm was higher by 25 % than that of paddy. The result indicated that the ratio of land rent oil palm was 1.25 times higher than wetland. The welfare of rice farmers was lower with the value of NTPRP 0,57 than oil palm farmers with the value of NTPRP 0,70.

Yellow latex is commonly called gamboge and is a latex produced in all parts of the mangosteen. Yellow sap becomes a problem when it gets out of the ruptured channel, and contaminates the aryl and pericarp. Ruptured channel of yellow latex is presumably because the walls of the epithelial cells of the yellow latex channels is Calcium deficiency. In addition, Boron has also the same function in maintaining the integrity of the cell wall. This research was aimed to know the roles of calcium and boron in controlling contamination yellow latex on the mangosteen fruit, and to obtain the best combination between calcium and boron in preventing the yellow latex contamination on mangosteen. The study was conducted in Purwakarta, West Java from November 2012 to June 2013. The study was arranged a randomized factorial with three replications. The treatment consists of two factors: dosages of Ca (0.0; 2.5; 5.0 and 7.5 kg / tree) and of B (0.00; 0.77; 1.55 and 2.32 g /tree). There was no interaction effect observed between calcium and boron fertilizer on fruit physical and chemical variables but there were significant interactions in quadratic levels of yellow latex contaminant in the mangosteen fruit. The percentage of fruit with minimum aryl contamination was 1.05 % at the optimum combination dose of 5.0 kg Ca/tree and 1.55 g B2O3/tree.

Rice is the staple food of Indonesia's population. Various problems occur in an effort to increase production and productivity. One problem is the attack of yellow rice stem borer (PBPK) which may result in yield losses up to 90%. Utilization of parasitoid is an alternative to suppress the attack of Yellow Rice Stem Borer. The study was conducted in Tabanan, covering three locations with the altitudes of 50, 300, and 550 meters above sea leve, and at the Plant Pests and Diseases laboratory of the Faculty of Agriculture, University of Udayana. The study aimed to determine the effectiveness of parasitization of the best Yellow Rice Stem Borer as a natural control agent at different altitudes. The method used was survey by taking a sample group of Yellow Rice Stem Borer eggs with a purposive random sampling in the area of 2.5 hectares (one block in each location was an area of 0.5 hectares) at each location. Observations on parasitoid found in Yellow Rice Stem Borer eggs were done on parasitoid species diversity, equality, abundance, parasitation level, sex ratio, and the pattern of parasitoid invasion. The results showed three species of parasitoid eggs PBPK as biological control agents. Parasitation level of T. rowani and T. japonicum was the highest at the altitude of 50 meters above sea level, while T. schoenobii at the altitude of 300 and 500 meters above sea level.
