Abstract

The objectives of the study are : (1) to design  land  suitability database for cultivation of the national valuable fruits, (2) to design the activation information of  fruits production, including land preparation until primary postharvest handling, and (3) to design the decision support system for valuable fruits on people’s orchads to produce fresh fruits. The study was conducted in Yogyakarta Special Region, from November 1999 until March 2000.  Two kinds of data used in this study were: (a) primary data, from the direct discussion with the experts, and direct observation in the fruits production center, and (b) secondary data were collected from library studies and Agriculture Agency Offices in each regency or municipality of the Yogyakarta Special Region.  The data in the salaccias production center was established from farmers which owned orchad more than one hectare. The results of  the study were : (1) land suitability database for national valuable fruits cultivation based on relational data, (2) computerize information system, namely Salaccia (Pondoh cultivar) and Mango (Arumanis, Manalagi, Golek, and Gedong cultivar) included : land preparation, planting, fertilizing, cultivating, pest and disease control, pruning, irrigating, harvesting, cleaning of fruits, sorting of fruits, grading of fruits, ripening (specially for mango), and storage of fruits, and (3) the system has been done to determine land suitability for fruits in Yogyakarta Special Region, and the result showed that 62.39 % was suitable between output system designed and the fruits produced by the farmer, namely manggistas, pineapples, mangoes, rambutans, durians, salaccias, and lawzons.

Abstract

This study was aimed to develop the model to predict the maturity and ripeness of durian based on its physical and chemical characteristics using neural network. The physicochemical and acoustic characteristics measurement was fed into the model as the inputs, which provided the levels of maturity and ripeness as the output of the model. The results suggested that the physico-chemical properties and the acoustic charcteristic decreased with the increase of both maturity and ripeness level of durian. The total solid soluble, the water content and the total sugar increased according to the fruits maturity. The total acids increased in the beginning of durian maturing process and then decreased when the maturity and ripeness level reached the mature-over ripened stage. Data training were done by model of neural network: model 4 output, with various node in the hidden layer 4, 6, 8 and 10 nodes. The results recommended that the best model to be applied was model 4 output with 4 nodes in the hidden layer and iteration 1000 and 5000 with the model accuration 87.5 % - 100%.
