 The efforts in increasing national rice production sustainability require new improved innovation technology continually and consistently, as the principle of the ICM. The research was aimed to obtain better technology than the current practice of cultivation of local farmers such as improvement of rice varieties, nutrient application method and plant spacing in order to increase rice productivity. The experiment was conducted on farmer’s field at Sukamandi Jaya village, Ciasem regency of Subang district, West Java, during the 2012 dry season and 2012/2013 wet season. The treatments were arranged in a Split-split plot design with three replications.The main plots were two fertilizer application methods: P1- local recommendation (urea -300 kg per ha, SP36-50 kg, KCl -50kg. P2 – Alternative recommendation guided by Rice Fertilizer Expert System/RIFES (Urea =320 kg/ha, SP36= 70 kg/ha KCl=130kg/ha); Urea was applied 3x namely at 7 dat, 21 dat and 42 dat (just before panicle initiation stage).Sub plots the planting methods were (equal spacing 25 cm x 25 (T1) cm and 25 cm x 20 cm (T2)). Sub-sub plots were new superior Varieties V1- the best local variety in the area, (Ciherang), V2- Inpari 14, V3- Inpari 17and V4- Inpari 6.The results indicated that technology components of ICM applied during the 2012 dry season can be improved by introducing the RIFES guided recommendation which is higher K rate, and introducing Inpari-14. These new practices increased rice yield from 5.5 t/ha (the present practice) to 7.6 ton fresh grains or GKP/ha, at 2012/2013 wet season.

Patchouli productivity in Indonesia is relatively low and varies between production centers. In order to increase patchouli productivity in Indonesia, Indonesian Spice and Medicinal Crops Research Institute (Balittro) has done several patchouli breeding activities from exploration results and obtained 25 accessions. The 25 accessions are characterized, evaluated, and selected, resulting in five accessions which are potential to be producetive and high quality, therefore the research was done in three different locations. It was done in three agro-ecological zones i.e. Bogor, Subang and Sukabumi starting March-Desember 2011, with the aim of knowing the morfology characteristics, result, and quality of the five accessions. The experiment was arranged in a Randomized complete Block Design with 5 replications and 5 reatments. The treatments were 5 patchouli accessions i.e: GR 3, GR 4, PWK 1, BRS, CLP, and Sidikalang variety as a control. The observed parameters were growth characteristics, yield and quality. The characteristics of growth included plant height, diameter of stem, number of primary and secondary branches and number of leaves. The characteristics of yield components were fresh and dry weight of herbs and quality characteristics were volatile oil content and concentration of patchouli alcohol. Results showed that there was interaction between the nature of plant genotype and environment, especially on the growth characteristics and yield i.e. fresh and dry weight, number of leaves, number of primary and secondary branches, width of canopy and width of leaves. There was no genotype interaction in plant height, leaf thickness, length of petiole and leaf length. Essential oil contents within three locations varied. The highest essential oil content was ; at Bogor, PWK accession with essential oil contens of 2.45 % and patchouli alcohol 35.39 %. At Sukabumi, CLP accession with essential oil content is 2.03 % and patchouli alcohol 38,03 % . At Subang, PWK accession essential oil content is 2.56 % and patchouli alcohol 39,70 %.

empedak (Artocarpus champeden), is one of the original Indonesian exotic plant species. The fruit tastes very sweet and sticky, very fragrant aroma and distinctive. Cempedak fruit is a fruit that has dissimilar maturity level. This study aimed to obtain cempedak fruit ripening technology that produces cempedak fruit's maturity to be relatively homogeneous and faster without having to change the physical and chemical characteristics. The experimental design used was a completely randomized design (CRD) 1 factor of ten (10) ripening treatment with two replications. The treatment includes a control (no treatment), wounding, carbide at a dose of 1, 2, 3, and 4 g / kg of fruit (C1, C2, C3 and C4) and Ethrel at several doses (1000, 1500, 2000 and 2500) ppm. Statistical analysis was conducted such as univariate and multivariate analyses. The results showed that treatments with calcium carbide and ethrel ripening may accelerate fruit ripening faster 3 days compared to the control treatment and wounding. The higher dose of calcium carbide and ethrel, TPT value and water content tend to be lower, whereas the higher value of vitamin C with the higher dose on the fourth day after ripening. Ripening treatment with doses of calcium carbide 2 and 3 g / kg were similar to ripening treatment ethrel 1500 and 2000 ppm total acid, vitamin C, total dissolved solids and water content after 7 days of ripening. Univariate analysis (anova) is effective in terms of providing information on the best treatment, while the multivariate analysis (manova and PCA) is effective in reducing the number of variables and determine the similarity of a variable.

Rural food security program has been implemented since 2006 and the number of selfhelp villages has achieved 825 villages. One of the goals of Demapan program is to achieve food security and reduce poverty. During the execution of the program the staple food shortage declined from 39.77% to 29.02%, weight of infants whose weight below the standard was reduced from 2.35% to 1.03%. Households under very poor category decreased significantly from 15,54% to 4.99% and poor categories decreased from 57.49% to 42.24%. Other effects were increased frequency of eating, consumption of animal food, improved clothing economic access, and access to health services. Empowerment of poor households have positive impact on self-esteem, gender aspects and entrepreneurship, which in turn contribute positively to the use of capital in productive business development for technology adoption. Poverty reduction in affinity groups can be enhanced by strengthening their institutional group, the effectiveness of empowerment, infrastructure support, coaching and funding commitments across sectors. Cross sectoral-support should be involved as the successful development respective of affinity groups and rural economic development in the perspective of inclusive growth for accelerating poverty reduction.

The main objectives in modeling of the growth curve is for growth of livestock description and prediction. The purpose of description is an attempt to be able to simplify the interpretation of the process to only a few parameters, while the prediction goal is to focus more on the method on how to predict from several parameters. The purpose of this research is to create a model of the growth curve of Holstein dairy cattle from birth to first mating age according to the situation and condition of industrial-scale dairy farm. Cow weight data used was obtained from weighing Holstein dairy cows maintained by PT Taurus Dairy Farm, Sukabumi, West Java from 2001 to 2011. There were 1221 cows involved, but only 373 cows covered the complete data from birth to first mating age for PT Taurus Dairy Farm. As for the data from BPPTU Baturraden 214 heads of cattle birth data is ready to be mated for the first time from 2010 to 2011. Data were analyzed using SAS 9.2 software with the procedure NLIN (non-linear). The resulting curve can be used as a standard growth curve of Holstein dairy cattle in Indonesia from birth until they are ready to be mated. Mathematical logistic models can be used to estimate the growth curve because it has a high degree of accuracy with the coefficient of determination (R2) of more than 90%. .

Muna is the main production center of cashew in Southeast Sulawesi Province. The cashew plantation in Muna has quality problems such as low production, low incomes and inefficient marketing system. Farmers’ bargaining position is weak because farmers do not have information that can be used as reference price. Price is determined by the cashew buyers which resulted in low selling prices at the farm level. The objective of this study is to analyze the market structure, market conduct and market performance of cashew in Muna. The market structure was analyzed with Herfindhal Hirchman Index (HHI). Market conduct was described descriptively, while market performance was analyzed by marketing margins, farmer’s market share and vertical integration. A purposive sampling was conducted in cashew production center in the District of Tongkuno Muna and the District of Kabawo between July 2013 to September 2013. The marketing agencies are farmers, village traders, sub district traders and inter-island traders (wholesalers at the district level). It showed that the cashew market structure is oligopsonistic which resulted in the action of colllusion between traders and cashew processing industry. The results of market performance analysis showed that the farmer markets are not integrated in the short run and long run. This showed that cashew farmers are price taker.

In Conjunction with the increasing of plant genetic resources development, the number of accessions of the turmeric plant is also increasing, making it difficult to differentiate between varieties, due to similar appearances. This research aimed to develop an expert system to identify the varieties of turmeric (Turina-1, Turina2, and Turina-3). Knowledge acquisition for building the expert system is performed in conjunction with an expert from the Indonesia Spices and Medicinal Research Institute. The knowledge acquisition process resulted in 13 input variables to describe a variety. The input inference process divides these 13 variables into two types: fuzzy and non-fuzzy. The non-fuzzy variables are: color of flowers, the base of leaf, and the flesh color of the rhizome which were used to decide whether the input description represents a Turina-1, Turina-2, Turina-3 variety or a non-variety. The remaining 10 fuzzy variables are: number of flowers per stem, plant height, number of tillers, leaf length, leaf width, rhizome weight per hill, number of parent rhizome, the number of primary roots, secondary roots and the levels of curcuma, which are used to determine whether the input description represents a Turina-1, Turina-2 or Turina-3 variety, using the Mamdani method for Fuzzy Inference System (FIS). In the testing phase, we used 100 data, which were already labeled according to the decision by the expert. The result shows that the system was able to correctly identify 89 of the input data.
