In Order to apply the agriculture technology or innovation, the farmers requires assistance by researches or extension agent to provide the expected results. The application of agricultural technology or innovation in farmers requires assistance by researchers or extension workers to provide the expected results. This study has an objective to determine the effectiveness among three correlation models, namely: Pearson, Kendall?s tau-b, and Spearman for analyzing the performance of assisting activities. The assessment was done based on the assisting data which collected in North of Bolaang Mongondow District, North Sulawesi Province. As the respondents, the primary data were obtained by questionnaires to 22 of the rice farmers who were randomly selected by PRA. The assisting data focused on the rice production aspect for both of pre-assisting and post-assisting cases. The effectiveness indicator among those correlation models has defined using the number of real analysis variables and the correlation coefficients. According to three models, they produced almost similar coefficient correlation for both of pre-assisting and post-assisting cases. Based on three models, a significant correlation variable which found was a correlation between the age and the experiences. For those significant variable, the differences among those models only appears in the degree of correlation. As a conclusion, the Pearson, Kendall?s tau b, and Spearman correlation models can be used as an alternative methods for analyzing the performance of assisting activities.

Bambara groundnut (Vigna subterranea (L.) Verdc) is a potential commodity to be developed in Indonesia, however, the production is done only once a year, therefore, it needs proper seed storage. The aim of this research was to study seed deterioration patterns of four bambara groundnut landraces stored in packages with different permeability in an open storage system for up to 6 months. This experiment was conducted from November 2015 to July 2016 at Seed Technology Laboratory, Department of Agronomy and Horticulture, IPB. Stages of experiment as follow: calculation of packaging permeability, seed storage, preparation and fitting data to regression equation.The packaging used in the study is aluminum foil, pp plastic and plastic sacks which have measured its permeability. The result showed that the seed deterioration of four bambara groundnut landraces in three packaging permeability has common sigmoidpattern with equation model: y = a / {1 + exp ((x + b) / c)}. The seed deterioration pattern based on SG and EC variables with the faster rate of decline occurred in Sumedang landrace packed in plastic sack (permeability = 1.4681 g/day m2 mm/Hg), thus having a shorter storability. The slower rate of decline occurred in Gresik landrace packed in aluminum foil (permeability = 0.098 g/day m2 mm/Hg), this means that it has a longer storability.

This study aimed to determine the similarity of the characteristics of each type of organic matter in suppressing the solubility of iron in soil and absorption in plants. This research was conducted in two stages. The first stage was conducted in the greenhouse to study the effect of organic matter to iron solubility in acidic sulphate soil. The research used a factorial design with 1 control and 3 replications. The first factor was type of organic matter used, B1 = rice straw; B2 = weeds; B3 = Combination of 50% rice straw and 50% weeds. The second factor was the incubation period of organic matter I1 = 2 weeks, I2 = 4 weeks, I3 = 8 weeks, and I4 = 12 weeks. The second stage was analyzing the profiles of the type of organic matter in order to evaluate the similarity of the characteristics of each type of organic matter. Based on the profile alignment, it was found that the three types of organic matter were not aligned. The types of organic matter had different roles in suppressing the solubility of iron in soil and its absorption in plants. There is a need to do a comparative analysis with Tukey method to the three types of organic matter.

The change in cattle price faced by farmers in the cattle fattening business when buying feeders and selling the beef cattle. This study was aimed to observe the efforts done by the farmers and the solutions that could be suggested. The purpose of this study was to analyze the effect of cattle price change on the demand for feeders and the supply of cattle which are produced by Bali cattle fattening businesses in West Nusa Tenggara. The results showed that the change of the beef cattle price on market level affect the demand for feeder cattle, which is one of the inputs fattening business. Instead the supply cattle of fattened does not effected by beef cattle price changes. Changes of the price of beef cattle on market level does not affect the supply of cattle fattened. Farmer income is determined by the price of cattle and price of fattened cattle and other costs incurred during the production process. It is concluded that the cattle price change affect to demand of feeder cattle with negative relation; but not influence to supply of beef cattle fattened.

Water balance modeling is one approach that can be used to predict the dynamics of soil water content for plant growth, so it can calculate the amount of crop water requirements, particularly at critical periods during which the soil moisture content is very low and in normal circumstan ces. The experiment wasconducted April-November 2010 in Merauke district of Papua provi nce. The collect ion of clim ate data (rainfall, temperature, humidity), land information(based on soil type and land use map, primarily to det ermine water holding ca pacit y and root z one depthof the soils). Land water balance analysis was con ducted for each a nalysi s of distri cts using Thornthwaite and Mather (1957). Furthermore, the results of water balance of land was mapping used the geographic information system (GIS) method for knowing the districts that have the periods of water deficit or water surplus. The results showed that the dom inant patterns of rai nfall in t he district of Merauke is pattern A is a pattern that suggests that there is a clear di fferen ce between the a mount of rai nfall duri ng th e rain y sea son t o dry season. Merauke district experienced a period of water deficit of about 4-7 months for a year. Sub districts that have a period and a high amount of water deficit isKuprik for 7 consecutive months. Sub districts that have a short period of deficit 4 months is Jagebob, Kimaan and Muting. The potential for planting food crops in Merauke district ranges from 5-7 months. The surplus per iod i s about 3-6 mont hs of November to May/June. Sub districts that have a longer period surplus isJagebob and Kimaant is 6 months. The most of the sub districts (6 sub districts) in the Merauke districthas a surplus of water> 1000 mm / year. There are only two sub districts that have surplus water <1000 mm / year is Kupri k and Sota. Sub distri cts t hatobtain high water surplus for the year is Semangga. Pot ential of th e short growing season found in Kuprik (3 months) while the potential of the growingseason is long (6 months) in almost every sub district (Semangga, Okaba, Muting Kimaan, and Sota).

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.

The statistical method for measuring rice productivity by the CBS is based on sample frame of households. At the implementation of this method, problems were encountered in terms of accuracy in the spread of the sample, the result is often debatable in applying the method in the field survey. To answer these problems, a survey of rice productivity has been developed through land survey framework approach or the method known as Area Frame Method. The purpose of this survey was to test the frame methodology for measuring frame rice productivity, and compare the results of the survey area rice productivity using area frames with the household listing conducted regularly by the CBS. The development of this method was expected to be used for problems that arise in the current method by considering the geographical conditions, the type of irrigation and government policies in order to increase production. Frame Area method has been tested in Cianjur (in 2012) and Garut (in 2013) in the province of West Java. Number of Mesh (land area 1,000 m x 1,000 m on the map ) in Garut was 120 Mesh. Each mesh was divided into five plots, so that the number of plots in Garut were 600 plots. Selection of sample plots was done by combining Systematic Random Sampling and Simple Random Sampling. The results of the trial method in the area of Garut showed that the productivity of upland and lowland rice were statistically significantly different as well as there were differences in the productivity of irrigated and non-irrigated lands, and there was no difference in the productivity of paddy land as recommended by the government with the conventional. However, the results of statistical tests on rice productivity of Area Method with the official method of CBS in Garut were not significantly different. This may imply that the sample selection method for measuring current productivity (CBS Method) can still be used, but it needs refinement to make the distribution of the samples stratified by altitude, stratification by type of irrigation and by the involvement of farmers who joined a government program

Integrated Crop Management (ICM) of maize has been disseminated since long time in all production centers in Indonesia, including Gorontalo. However, the application at the farmer level has not been optimal so that it has not yet expanded. This study aims to measure theÂ adoption rate of the components of maize ICM technology, and to identify socio-economic factors that affect the application of maize by farmers in Gorontalo District. The study was conducted on lowland dryland agro ecosystem in Tibawa Subdistrict and highland dryland agro ecosystem in Bongomeme Subdistrict, Gorontalo District. Site selection was done purposively with the consideration that the districtÂ and sub-district were maize production centers, and had implemented various programs to increase maize production with the application of ICM from various government agencies. The survey was carried out in February-May 2015. The adoption rate of maize ICM component by respondents farmers used the weighting (score). Socio-economic factor analysis methods that influence the application of maize ICM using logistic regression model. The results showed that the accessibility of farmers to the supporting sources of farming such as capital (credit), market, and technology sources significantly affected the adoption of ICM technology. Steps that can be taken to improve farmers access to credit in formal financial institutions (banks) include providing flexible credit scheme, easy, not procedural, and not burdensome. Increased access of farmers to the source of technology can be done through increased frequency of extension, the implementation of technology dissemination that reaches more farmer groups and farmers.
