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.

Abstract

Molleculler study was conducted to identify several species of Trichoderma isolate from several plant (Pine, Cacao, Gliceria, Nutmeg, Bamboo, Coffee, Potato). The growth of eight species Trichodermaafter pelleting formulation has been observed. Pellet Trichoderma harzianum have good ability to growth on PDA medium after 4 weeks storage. Base on their mycelium diameter growth on PDA, T. harzianum have selected as potential species on pellet formulation growth. Several dose of pellet formulation have been applied for controlling Phythopthora disease. The application of T. harzianum pellets in the form of a 2 g / 100 ml (S1) suspension effective in inhibiting the development of Phytophthora sp in cacao seedlings, when the higher concentrations of T. harzianum pellets applied to cacao seeds,the disease severity increase. Pellet Trichoderma could be use as biological control agent of cacao seedling in certain dosage.

Abstract

The productivity of land and plants have decreased slowly, due to the use of inorganic fertilizers continuously. Efforts to improve productivity are reducing inorganic fertilizers and returning organic matter to the soil. The aim of this research are (1) to identify the chemical characteristics of biofertilizer with an indigenous microorganism as bioactivators and (2) to study the effect of biofertilizer on nutrient uptake of maize plant. The research was conducted at Laboratory, Greenhouse, and Experimental Field of Politeknik Pertanian Negeri Payakumbuh, West Sumatra Indonesia. The first step experiment in the Laboratory was produced indigenous microorganism from banana humps. The second step of making bio-fertilizers in Greenhouse used a Completely Randomized Design with four treatments of indigenous microorganism (IMO) level 0%, 10%, 20%, 30% in biofertilizer with five replications. The third step of biofertilizer application on the Experimental Field used Randomized Block Design Factorial arranged with two factors and three replications, the first factor IMO level in biofertilizer (M) 0%, 10%, 20%, 30% and the second factor was the dosage of inorganic fertilizer (P) 0%, 50%, 100% of the recommended dosage, 12 combinations of treatments were obtained. Results showed that microbe consortium (Enterobacter cloacae, Bacillus subtilis, Pseudomonas fluorescens, Aspergillus niger, and Trichoderma asperellum) in biofertilizers with different levels would affect the chemical characteristics of biofertilizer. Biofertilizers influences nutrient uptake of P and K maize plant, while inorganic fertilizer influences nutrient uptake of N and P maize plant.

Abstract

West Sumatra-Indonesia has potential to plant coconut due to the coastal location, sunshine level with average temperature 27oC. Coconut is a very productive plant. Coconut dehusking is one of the process that takes a lot of time and energy. Most of the farmer still using human manual labour with the help of tools made of iron or wooden crowbar that is mounted standing vertically with the blade facing upward about 80 cm from the ground. To increase the number of coconut products, it is designed the coconut dehusker machine. The main component of the machine were two rollers that rotate each other in opposite directions with each roller embedded iron-shaped nails that work to tear the coconut husk. Each roller has a different rotational speed. This machine has dimensions of 98 cm x 51 cm x 95 cm. Roller length is 50 cm and diameter 4 inches. The power source of the machine is a 2 HP electric motor, the speed was reduced by using 2 speeds reducer with the ratio of 1:20 and 1:30 respectively. From the performance test of this machine can dehusk 100 coconuts per hour. The operational basic cost of the machine equal to Rp 129.89 per coconut (about 1 cent) and Break Event Point is 12.387 coconut per year from the result of the performance test. From the economic analysis machine can be concluded that the use of this machine is better when compared to human labour which has limitation to duration and capacity.
