Abstract:Microbial consortium exploration in an ecosystem is a series of activities aimed at obtaining microb living in a consortium and beneficial to plant growth.The study aimed to obtain leaf and soil samples in various plants within an ecosystem, as a source of a consortium of microbial phyllosphere and rhizosphere to be tested for their effectiveness in increasing the growth and yield of rice crops. The method of determining the location is based on the method of transect sampling/line intersep plot design on an area of 5,196.02 km2. Site determination based on purposive sampling includes ecosystems: rice fields, gardens, pastures and forests.The results showed that, Sigi District has biodiversity in various ecosystems that have potential as source of consortium of microbial phyllosphere and rhizosphere. From the exploration results obtained a sample of 48 species of plants consisting of plants under the level of 30 species, 12 pile poles and 6 types of stakes. The results of the isolation of leaf and soil samples obtained 144 consortium of microbial phyllosphere and 48 consortium of microbial rhizosphere. The obtained consortium was then tested for its effectiveness on the growth and yield of rice crops in the next stage of the study

Abstract:This study aimed to examine the effectiveness of some insecticides on the population development and attack Liriomyza sp on local Palu onions. The research conducted from Februari to April 2017, at Guntarano village, Tanantovea Sub-District, Donggala District. The study used Randomized Block Design (RAK) consisting of four treatments, namely Po.Control; P1. Abamectin; P2. Azadiractin; P3. Dimohipo. Each treatment was repeated three times so that 12 treatments were obtained. The results showed that the insecticidal treatment had an effect on the development of the varied Liriomyza sp. Adult population at various plant age levels. Observations on plant age 5 and 6 of MST showed that abamectin insecticides were effective in suppressing the growth larvae populations of Liriomyza sp compared with the treatment of Azadiractin, Dimohipo and non-treated insecticides.

Abstract:Indonesia as the world's major producer and supplier of rattan, but most of Indonesia's rattan production relies on natural rattan sources. The fact that natural rattan is generally harvested after the age of more than 4 years, is not proportional to harvesting at any time, and threatens the preservation of rattan, so research on rattan cultivation is important. This study focuses on the growth and absorption of Noko rattan seedlings varieties (Daemonorops sp.) in response of organic and inorganic fertilization. Research was conducted in the glass house of UNTAD, using factorial design of 2 (two) factors. Factor I consists of 2 (two) levels, namely: (B0) without bokashi, and (B1) bokashi 10 t / Ha. Factor II consists of 7 (seven) variations of Nitrogen and Phosphorus treatments. The results showed that the treatment of organic fertilizer and inorganic fertilizer had no significant effect on dry weight or nitrogen uptake (N) or N network. However treatment with bokashi showed a tendency of dry weight and alsoN uptake or N tissue higher than treatment without bokashi. In this study, treatment with bokashi added Urea fertilizer gives the best influence on the growth of Noko rattan seedlings.

Abstract:Increased competitive advantage (competitiveness) of Indonesia cocoa becomes an important agenda in order face tight global competition. This research aimed (1) to determine the competitive advantage (Comparative Advantage) of cocoa commodities; (2) to investigate the competitive advantage of cocoa commodities (comparative advantage); (3. The research used a descriptivi-qualitative approach. The population included 5 regencies in West Sulawesi Province. The secondary data were obtained from the work force in the cocoa plantation in both West Sulawesi Province and lndonesia and from both the West Sulawesi Provincial Central Statistics Agency (BPS) and the National Central Statistics Agency. The analyses used were the Locational Qoutient (LQ) and SWOT analyses. The research results revealed that the cocoa commodities in West Sulawesi Province had a comparative advantage in the labor force in the cocoa plantation Sector. In general, since the last five years has the value of LQ> 1 or the average reaches 8.47. While the comparative advantage of the land area of cocoa based on a comparison with the Sulawesi area LQ value reached 2.99 in 2012. While the 2013-2014 experienced a drastic 0,95 and 0,89. That matter decline due to land conversion from cocoa to sawait.

Abstract:This research aims to study and know the factors the production of red onion plant, has been implemented in Bulupountu Jaya, Sigi Biromaru, Sigi, Central Sulawesi. The results of this research is expected to be an information for the farmer about the factors that affect the production of red onion plant. The research was conducted from June to August 2016 in Bulupountu Jaya , Sigi Biromaru , Sigi , Central Sulawesi. Selection of the location of this research is based on that Bulupountu Jaya Village is the majority of red onion farmer. The method used is quantitative research method by survey and interviews to farmers red onion farming in Bulupountu.Location determination by purposive sampling and respondents by Multistage Random Sampling, through the stages : a.Specify the hamlet representing Bulupountu area, Specify farmer groups in each hamlet, c. Specify five respondents in each farmer groups, so there are 20 respondents. The results of this research indicate that the factors of land area, the amount of fertilizer, the number of seeds, the use of pesticides and pest control affect production in the development of onion farming in Bulupountu Jaya Village, Sigi Biromaru Subdistrict Sigi Regency Central Sulawesi Province

Abstract:Onion farmers role in Sigi central Celebes as the main actor to maintain the natural resource is much determining the sustainability of future agriculture. Therefore, the farmer behavior on pest controlling is need to be improved and developed, also about the factors impacted. This study is aim to learn direct effect of locus of control and the manner towards onion farmer behavior on pest controlling in Sigi. To answer the purpose that has been told previously, we are going to do several step which is integrated to one another and systematic to gain the aim. This research is a kind of survey research and correlation ex-post facto. Respondents is the onion farmers in Sigi Biromaru as 200 farmers which obtain by proportional simple sampling principle. Primer data is obtained by several instrument such as; a). queisioner, b). test, c). observation, and d).in- depth interview. The first instrument used would be validity and reliability test. Description analysis is used to serve the data, size data, size central, and also dissemination size. Inferential analysis is used to examine the hypothesis with path analysis. The result of the study prove that farmer cognition about Integrated Pest Controlling (IPC) positively impact and significantly towards farmer behavior on pest controlling using IPC principle. Locus of control positively directly effect and significantly towards farmer behavior on pest controlling using IPC principle. Farmer cognition about integrated pest controlling and locus of control positively effect to farmer manner in Oloboju village. Farmer cognition about IPC, locus of control , and manner positively effect towards the farmer behavior on pest controlling. Farmer cognition and locus of control indirectly effect through farmer manner toward farmer behavior on IPC. This means the proliferation of farmer cognition about IPC and locus of control through farmer manner would triggered a change of farmer behavior on pest controlling and appropriate to IPC principle
