Different types of rice pests, have been reported. The explosions and a potential pests are Rice Stem Borer (Tryporizasp.), Brown Planthoppers (Nilaparvata lugens), Green Leafhoppers (Nephotettix virescens), and Rats (Rattus sp.), wichan obstacle in creating stability of rice production in Bone. In rice ecosystem, natural enemies of arthropod predatorsare most instrumental in suppressing the pest population. Fluctuation in population density of natural enemies, affectingpests presence. Efforts to suppress pest proportions through IPM, is a strategy of lowering the level of pests and damageto rice crops. This study aims to identify and measure the relationship strength between pests and natural enemiespopulations in some rice varieties after IPM, using correlation and regression analysis. Observations conducted in Bone,from May to August 2012, with 2 observed variables, pests and natural enemies populations in Inpari 6, Inpari 10, Inpari16, Ciherang, Cigelis, and Mekongga. Data analysis were performed using correlation and regression analysis. Theresults showed a high degree of correlation between pest and natural enemies (predators) populalions, characterized bya positive correlation coefficient (0.957) and significant at the level of 0.01, where each increase in the intensity of pestpopulations, will be followed by increase in the number of natural enemies captured.

Muna adalah sentra produksi utama jambu mete di provinsi Sulawesi Tenggara . Perkebunan jambu mete di Muna memiliki masalah kualitas seperti produksi yang rendah, pendapatan rendah dan sistem pemasaran yang tidak efisien . Posisi tawar petani lemah karena petani tidak memiliki informasi yang dapat digunakan sebagai harga referensi. Harga ditentukan oleh pedagang jambu mete yang mengakibatkan rendahnya harga jual di tingkat petani. Tujuan dari penelitian ini adalah untuk menganalisis strukur pasar, perilaku pasar dan kinerja pasar jambu mete di Kabupaten Muna. Struktur pasar dianalisis dengan Herfindahl Hirchman Index (HHI). Perilaku pasar digambarkan secara deskriptif sedangkan kinerja pasar dianalisis dengan margin pemasaran, pangsa pasar petani dan integrasi vertikal. Metode pengambilan sampel dilakukan dengan purpossive yang dilakukan di sentra produksi jambu mete di Kabupaten Muna yakni Kecamatan Tongkuno dan Kecamatan Kabawo dimulai bulan Juli 2013 sampai September 2013 Lembaga pemasaran yang dianalisis adalah petani, pedagang pengumpul desa, pedagang pengumpul kecamatan dan pedagang antar pulau (grosir di tingkat kabupaten). Hasil penelitian menunjukkan bahwa struktur pasar jambu mete merupakan struktur pasar oligopsoni yang mengakibatkan terjadi kolusi antara pedagang dan industri pengolahan jambu mete. Hasil analisis kinerja pasar menunjukkan bahwa pasar petani tidak terintegrasi dalam jangka pendek dan jangka panjang. Hal ini menunjukkan bahwa petani jambu mete adalah penerima harga.

Shift share Analysis is one of analysis tools that can be used to analyze shift and share of overall of sectors of PDRB. The research was conduted to identify shifting overall sectors of PDRB of South East Sulawesi with shift-share analysis. The research used GDP of Indonesia, PDRB of South East Sulawesi and PDRB of cities/regenceis in South East Sulawesi 2003 and 2013 year base on constant price at year 2000. The result of research showed that application of shift share analysis can give overview about agriculture transformation in South East Sulawesi. Developing agricultural sector in South East Sulawesi depends on national development. The growth of agricultural sector in South East Sulawesi is classified as slow, and have Net Shift (NS) around IDR 144.868,720 million. Agricultural sector also has competitive advantage, specialization and also allocation effect. Shift share analysis also showed that agricultural sector has strong linkage with other sectors and has positif influence with other sectors to push regional output. This analysis needs to be applicated at micro levels to get agricultural commodities transformation that has competitive advantage and specialized to develop for increasing regional output in South East Sulawesi.

Farmersâ household in the village involve in many activities both farming and non-farming activities. This involvement affect the time allocation for farming, which in turn will have impacts to the household income. Therefore, there is a need to study the time allocation pattern of farmers, non-farming job opportunities and other factors that affect the working time allocation, income and farmersâ household expenditures. The research question are: (1) how the work flow patterns in the allocation of household farmers in rice production area and why rice productivity is low? (2) whether job opportunities in non farm business influence the flow of work in farming and what factors affect the flow of work, household income and farmers expenditure?. The purpose of this study is to analyze the factors that affect the working time allocation, income, and expenditure of farmers in the rice production area. The research was conducted in Sigi, Central Sulawesi Province on December 2015 â Pebruary 2016, using cross sectional data in the household based economic approach applying a model of simultaneous equations. The results showed that non-farm activities have played important roles in the rural economy, especially domestic rice farmer household. They are not only contribute to household income but also in to working time allocation. In terms of the working time allocation, farmesr do more non-farm activities than paddy farming activities. Male household membersâworking time allocation is the highest activities compared to the female household members in the farm or non farm. Meanwhile, in terms of income, the contribution to farmers income from non-farm is greater than from farm. Food consumption is the highest expenditure in the farmer household.

Shallot is an important vegetable commodity for most Indonesian people. Shallots production is not yet able to supply the domestic consumption, and some is still met through imports. The challenge to produce shallots will be more complex, such as: the desire of consumers to high-quality products and environmentally friendly, as well as competition with similar products in the era of free trade. Based on these reasons, research has been done and the purpose of this study was to analyze the factors affecting shallots production, measuring the level of technical efficiency and economical efficiency. The study was conducted in Nganjuk District by taking 179 respondents from four sub districts. Interviews were conducted in October and November 2013, planting shallots April unti August 2013. Methods of analysis using the stochastic frontier production function to look at the effect of inputs on shallots production, followed by the analysis of technical efficiency (TE), allocative efficiency (AE) and economical efficiency (EE), and the final analysis of competitiveness using the Policy Analysis Matrix (PAM). The independent variable inputs consist of land (X1), seeds (X2), NPK fertilizer (X3), organic fertilizer (X4), labor (X5) and pesticides (X6). The analysis showed all independent variables significantly affected shallots production, where the value of the elasticity of the independent variable X2 is the highest, amounting to 0.2822. The analysis also obtained an average value of TE is equal to 0.808 means farmers are efficient, although there are farmers who are still not efficient. Although TE has been achieved, but is economically inefficient, because the average value of EE only 0.509. From PAM results it can be seen that farming shallots in this study has a competitive advantage but do not yet have a comparative advantage.

High salinity is one of the major abiotic stresses affecting rice production. Previously, we have identified transposonDs insertional mutant rice lines cv Nipponbare showing improved tolerant under salinity stress The objective of thisresearch was to determine the Ds insertion site in chromosomal DNA from one of the salt tolerant mutant line (170-10) and identify the genes in the proximity. A specific amplicon around 450bp from the mutant rice line 170-10 wassuccessfully isolated with TAIL PCR technique using the degenerate and a specific Ds primers. Bioinformatics analysesfound that the insertion was located in a putative CDS designated as Os11g0686500 in chromosome 11 at the 2nd exon.Two putative CDS’s within the proximity of the Ds insertion site downstream and upstream the insertion sites were alsoidentified.

So far, regression analysis is used to model the mean of response variable as a function of some independent variables, using the least squares (LS) method. In general, the LS method is able to describe well the measure of central tendency, however it is not robust against outliers. Therefore, in certain cases, a regression analysis that minimizes the sum of absolute residuals (least absolute deviation - LAD) is required, which is more robust against outliers. So far, the value of the regression coefficient is not modeled and only depends entirely on the data processed. In some cases, the sign and the value of regression coefficients need to be controlled, in order to be in the meaningful range. The results of this study showed that the modification of the constraints on the LAD regression able to control the regression coefficients to be in the meaningful range. The results of bootstrap showed that distribution of controlled regression coefficients were different from distribution of uncontrolled regression coefficients.
