Abstract

Mindi is one of commercial tree species for its timber. Sustainable management of mindi community forest can be obtained by inter-planting the trees with agricultural crop such as soybean. This study aimed to analyze physiological respond of mindi and soybean, which were planted in an organic agroforestry system. The research was done in Conservation Unit for Medicinal Plants at Cikabayan, Bogor Agricultural University (IPB). The first study was about the growth of mindi saplings in monoculture and agroforestry systems (with soybean). The experiment used completely randomized design (CRD). The second study was about the growth of soybean in monoculture and agroforestry systems (with mindi), and used split-plot design. The result show that nutrient uptake of N, P, and K in agroforestry system was higher than in monoculture. The increase of nutrient content in agroforestry system led to the higher increase of growth dimensions of mindi tree than the ones in monoculture. The content of soybean chlorophyll planted in agroforestry system was higher than the ones in monoculture. Soybean in agroforestry system had higher nutrient uptake of N, P, and K compared to the ones in monoculture. Soybean productivity in monoculture system showed higher result than the ones in agroforestry. Keywords: chlorophyll, monoculture, root, tree dimension, varieties

Abstract

The objective of this research was to formulate a policy strategy for integrated pest management by using SWOT AHP methods (case study on vegetable cultivation in Lampung Province). This method used A’WOT; the combination of AHP (Analytical Hierarchy Process) analysis and SWOT (Strength-Weakness-Opportunity-Threat) analysis. The analysis result showed the main strength factors becoming the base for sustainable agricultural business were the availability of good structures and infrastructures both in production and marketing, and the availability of sufficient production structure (seeds) with good quality and quantity. The weakness factors becoming concern were dominantly lack of institutional funding (capital) for vegetable business, many problems in the integrated pest management (IPM) technology implementation stage, many problems in good agriculture practices (GAP), and numbers of families making their life as farmers. The opportunity factors were the availability of IPM and GAP technologies, growing campaign for consuming domestic products reducing import, and high government commitment to improve vegetable farmers’ welfare. The threats to concern were no protection operational base and farmer’s empowerment, very few institutional funding (capital) for vegetable business, and many problems in the GAP and technology implementation. Six strategies becoming priority in order were drafting the regulation and standard of operation that regulate IPM and GAP implementations; strengthening farmer’ institution, capital and agricultural insurance; drafting legality of operational protection and farmer’s empowerment; agricultural intensification in order to improve quantity, quality, safety, and environmental insight for food security and independency; optimization of technology transfer by socialization or education of IPM and GAP for vegetable crops; and inexpensive IPM system based controlling technology development and effective and efficient of alternative production structures.
