The study was started in September 2018 and terminated in December in the same year. The study site was a large irrigated rice farm belong to farmers with size around 40 hectares. The farmers plantedInpari 32 and Inpari 42 rice varieties twice a year. Rodent has been recognized as the most destructive pest in this area which accompanied by brown plant hopper, stem borer and virus as the minor pests and disease of the rice crop. The objective of this study was to control the rice field rats as the main pest contributing some losses to the local farmers. The second purpose was to determine the effectiveness of our ecologically based rat control technology which implemented by integrating several components. At the beginning of cropping season we performed sanitation, mass hunting and fumigation on the main habitats which continued by setting a TBS (Trap Barrier System) and LTBS (Linear Trap Barrier System) in different habitats. The TBS functions as a lure crop by planting those rice crop three weeks earlier than surrounding areas, as the rice field rats prefer to the generative stage. The LTBS was assembled to protect the next staggering crop by trapping rats regularly on their main habitats within a whole season. LTBS was also effective to catch the rats which move back and forthto the rice field and village after harvesting. We have set four units of TBS and four units of LTBS during the cropping season which incorporated with 48 bubu traps. We also protected seed nurseries by erected plastic fence combined with 16 bubu traps along the fence. We recorded the number of rat captured from those activities along the cropping season. These components of rat control technology were effectively catch lots of them within a cropping season accounted for 2,306 individuals. These actions provided positive impacts to the local farmers by decreasing rat population and increasing the yield. The average of yield increased from 1.9 ton/ha to 6.4 ton/ha after we performed rat control intensively. The yield data before and after implementation of rat control technology was compared and analyzed. The results indicated that there was a significant difference between those values. From this point it seems that farmer eager to adopt the technology for the next planting season.The study was conducted in Ciptamarga Village, JayakertaSubdistrict, Karawang District, West Java - Indonesia within one cropping season in 2018.

The assessment parameters are rice production, government programs, and farmers’ knowledge in managing land. This approach was carried out by field observations and interviews with informants such as the Head of the Division of Food Crops in Gowa Regency, extension agents, farmer group leaders, and farmers. Primary and secondary data are comparatively analyzed. This aims to be able to see and describe the phenomena regarding the empowerment of farmers in the three villages. The results showed that the empowerment of farmers usually done by doing field school, socialization, technology demonstration, and making demonstration plots. The highest rice production in 2018 is in Julubori Village which is 15 tons/ha, the intermediate rice production is in Tetebatu Village which is 6.9 tons/ha, and the lowest production is in Toddotoa Village which is 6.8 tons/ha. The main contributing factor for the success of rice production is the implementation of government-supported programs. The inhibiting factors are the low quality of human resources, the distribution of seeds and the planting season that is not a series of time, the limitation of agricultural equipment, and the inadequate availability of irrigation networks.Rice production is vital because of its impact on the national economy.

The treatments consisted of basal ration consisted of 11.8% forage and 88.2% concentrate (T1), and ration consisted of 11.8% forage and 78.9% concentrate supplemented with 9.3% linseed (T2), 9.3% linseed protected with 10 g/kg formaldehyde (T3), or 9.3% linseed protected with 34 g/kg cinnamaldehyde (T4). All goats received Odot Grass and concentrate at the level of 5% of body weight. The results showed that the protection using both formaldehyde and cinemaldehyde had no significant differences (P <0.05). Ammonia concentration is not affected by the treatment of protected linseed use. Microbial proteins analyzed by the Lowry method gave different results not significantly. This shows that the four treatments were able to provide nutrients for rumen microbial. Protein digestibility of rations and protein contained in milk from the four treatments showed that it did not differ between treatments.
