Forecasting of Indonesian cashew export price has been conducted using artificial neural networks. The best forecasting was found by using one hidden layer with seven neuron and activation function bipolar sigmoid in hidden layer and binary sigmoid in output layer. The result show that the price of the Indonesian cashew export will still low in 2008 and 2009. This will lead to low price of cashew product in farm gate level and at the end lowering the income of cashew farmers.

Inflation rate is one of the most important macro economic indicators that has been attempted to be controlled by the government. Retail sugar price is one of the determining factors influencing the inflation rate that is affected by several factors especially effected by distribution system. This study is aimed to analyze affecting factors on sugar retail price and to analyze correlation between sugar distribution system and inflation rate using error correction model. The results of this study show that import price, farmer reference price, and distribution costs are three main factors affecting the sugar retail price in Indonesia. However, the sugar retail price is inelastic with respect to the changes of these three factors. More over, the study in 45 main cities in Indonesia indicated that for 1% increasing in distribution cost will caused as much as 0,001 – 0,003% increasing in inflation rate.

A large amount of digital data has been collected by Indonesian Center for Agricultural Land Resources Research and Development (ICALRD) since 1987/1988. Since then digital data has become an integral part of the ICALRD’s soil resource database system. To meet the escalating need of spatial data by end users as well as to ensure the sustainability of digital data service like the one of the analog data service, digital data availability must be maintained and digital data management system should be developed. To implement these strategies, various means and tools have been provided. To serve users more efficiently and effectively, an integrated land resource information system based on location in Web design and Interactive CD format, structured backup data system management, catalogue of Indonesian land resources map system, and the prototype of information system of land evaluation for Agriculture have been developed and published by ICALRD. The ultimate goal of is to optimize the utilization of land resources database information to public especially for supporting agricultural development.

Phenotype of high generation inbred lines of maize included QPM was homogeneous such as plant height, ear height, size of ears, and grain yielded. Hotelling’s analysis (Γ2) was applied in order to identify seeds F1 single cross hybrid in two females inbred (MR4Q and MSQ.K1C0.9-2-1) and a male MR14Q as a tester. Six variables were analyzed by pooled hypotesis that the means of two females has not different significant at 5% level. The result shown that which was much higher than Γ2 = 37.059 in table value (Γ20,05(6;96)=6,253). The hypotesis of H0 was rejected and could be concluded that even though two variables (diameter of ears, and shelling percentage) were less than 10% of different means between MR4Q and MSQ.K1C0.9-2-1 if pollinated by tester of inbred MR14Q.
