Problems in the assembly of hybrid papaya for improving fruit size is limited information of proper parents, a good hybrid combination and limited other genetic information. The aim of the research is to analyse general combining ability (GCA), specific combining ability (SCA) and the analysis of genetic characteristics related to the character of the size of the fruit on the five parents papaya using Griffing methods I and II approach. The study was conducted from January 2010 to December 2013. The full diallel population and half diallel population genetic material using five parenst of papaya. Papaya parents used were Merah Delima (BT-1), BT-2, Carmina, Carmida (BT-4) and Dampit. Research was arranged in a randomized block design with three replications. The results showed that there was a significant reciprocal effect on Griffing model method 1 causing different values of SCA in the same combination of crosses. There were no differences in GCA estimation values using Griffing Methods I and II. Parent Dampit has the highest positive GCA predictive value, while the BT-2 and BT-3 have negative GCA estimation values for all fruit size characters. Based on the SCA estimation using Griffing Method I, the crossed pair has the highest SCA guess value of BT-4xD and BT-1X D. When using the griffing method II, the crossed pairs of BT-3 x BT-4 and D x BT-4 have the largest SCA estimated value for fruit size. Based on the griffing method I and II, it is known that more fruit size characters are controlled by the additive gene, so improving the fruit character can be through the selection.

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

Sustainable agriculture having high complexity, especially related to the choice of using inputs that could potentially harm the environment or often called a detrimental input. In order to realize sustainable agriculture, the level of efficiency of the use of these inputs must be able to measure, especially from the aspect of environmental efficiency. The objective of this research in to analyze the environmental efficiency (EEnv) with a detrimental input variable namely the Nitrogen surplus in shallot farming through approach Stochastic Frontier Analysis (SFA). At the initial stage has been built translog stochastic frontier regression model consisting of the response variable namely the production of onion, five independent variables, namely land, seed, Phospor fertilizer, Kalium fertilizer, labor and pesticides, as well as one independent variable is a surplus of nitrogen as a detrimental input. Stochastic frontier translog regression models were built to explain some of the interactions between several independent variables affect the production of shallot. Some interactions are significant, namely seeds and pesticides, fertilizer P with a surplus of nitrogen, and the interaction between K fertilizer with nitrogen surplus. From the regression model can also be calculated value of elasticity, where the elasticity of independent variables namely seed is the highest, equal to 0.1687. Furthermore stochastic frontier translog model can be calculated value EEnv, the results show the value of EEnv still low at only at 0.2765. This may imply inefficient shallot farmers from the aspects of the environment, especially if associated with the use of nitrogen fertilizer. Although technically shallot farmers have achieved a level of technical efficiency (ET), which is indicated on the ET value of 0.9475.

Land conversion causes competition in land use, and thus it is necessary to select leading commodities based on agro ecological zoning (AEZ). This study aimed to determine the leading commodities of food crops in Bantul Regency agro ecological zone. This study was conducted on March 2015. The data used was time series data of food crops harvested between 2008-2012 and agricultural commodities zone maps year 2013 based on AEZ with scale 1:50.000 obtained from the Statistics of Indonesia, Agriculture and Forestry Office, and AIAT. Commodities with comparative advantages were analysed by Location Quotient (LQ) while commodities with competitive advantages were analysed by Shift Share Analysis (SSA). Leading food crops commodities were determined through an overlay process using the ArcGIS software covering analysis results of LQ, SSA and agricultural commodities zone maps based on AEZ with scale 1:50.000. The result showed that the wetland paddy is a leading commodity in the study area. Based on comparative and competitive advantages, and compatibility with agricultural commodities zone based on AEZ, wetland paddy is the most leading commodity compared to corn, soybeans and peanuts. It is because of the distribution of this commodity in 10 districts (Sanden, Kretek, Pundong, Bambanglipuro, Pandak, Bantul, Jetis, Banguntapan, Kasihan, and Sedayu) with total area of 11,667 ha or 39.4% of agricultural land in Bantul Regency
