The use of botanical insecticide based on local resources to increase swamp rice yield in South Kalimantan, Indonesia

The purpose of science and technology activities for the community is to provide skills to farmers groups inutilizing the potential of existing natural resources as an alternative to ducks, utilizing high-protein ammonia bran, andmaking herbs as additive feed. Specific targets to be achieved are the fulfillment of livestock nutrition needs, especiallyducks with resource utilization with the fulfillment of food needs. Not only use the feed without processing. Through thisactivity farmers and agricultural extension, workers are expected to synergize to learn to utilize available local food,raising public awareness to utilize local resources into the nutrient-rich feed. Method of implementation of activities to becarried out is the socialization of activities on farmer groups, training for members of farmer groups, how to make a feedwith some feed processing technology and assistance to farmers. Output target IbM program is an alternative ration forducks, ammonia bran as a source of protein, herbal medicine. The method used is PRA (Participatory Rural Appraisal) /RRA (Rapid Rural Appraisal). Learning methods, extension training, training, and visits (Laku), field school education(SL), demonstration plots, guidance and mentoring, learning by doing. The resulting results of the system. Breeders arenot familiar with feed processing technology and farmers have not utilized local feed as a constituent of rations. Thetechnology applied to the breeder group is to use herbal ingredients as a feed additive, making silage as a source ofprotein one source for duck livestock

Red spinach (Alternanthera amoena) is one of the vegetable commodities that many people in demand for consumption because of its high nutritional content. Efforts to increase the production of red spinach often experience various obstacles. The main obstacle that limits the productivity of red spinach in the tropics is the number of Plant Disturbing Organisms in the form of pests and potential diseases that can attack and decrease the production of spinach. One of the pests that often attack spinach is the existence of army worm (Spodoptera litura F.). Therefore, farmers need a way to eradicate the pest. This research is experimental using Random Complete Group. The data obtained were analyzed with variant analysis (ANOVA) in one direction and continued with LSD (Least Significant Different) test. Provision of botanical insecticide done by spraying the extract of leaves and seeds mimba with concentration dose 0%, 5%, 10% and 15%. In the final analysis of mortality data of army worm (Spodoptera litura F.) treated with mimba leaf extract obtained significant value of 76.263 at a significant level of 0.05 so it can be concluded that there is influence of mimba leaf extract on mortality of army worm. In the final analysis of mortality data of army worm (Spodoptera litura F.) treated with mimba seed extract obtained significant value of 78.625 at a significant level of 0.05 so it can be concluded that there is an effect of mimba seeds extract on mortality army worm.

Window Method

Nerve injuries are a common pathology in hand trauma. The consequences are drastic both for patients and doctors/medical system. In many cases direct coaptation is impossible. A nerve graft should be used in the case of a neuroma, trauma or tumor, for restoration of nervous influx. The aim of this study is demonstrate that by grafting restant nerve stumps with muscle-in-vein nerve grafts we obtain good result in terms of functional and sensibility recovery and also our method �window-vein� is a good way of prolonging nerve grafts. The method of study is experimental. We worked in the laboratory in optimal conditions for carrying out of muscles-in-vein nerve grafts (nerve grafts size 1.5 cm-3 cm). We used acellular muscle grafts with the chemical extraction method.The study was conducted on experimental animals (Wistar male rats).We used 30 experience animals in 3 equal groups (classical group and muscle-in-vein nerve grafts-2 nerve grafts of 1,5 cm central sutured and the third group with muscle-in-vein nerve grafts, window-vein method, 3 cm). At 4 and respectively 6 weeks postoperative at the quality tests we observed the progress with the footprint test. The operated hind in comparison with the healthy hind was 86% recovered and similar with classic nerve grafts. Quantitatively the number of regenerated axons in the group with muscle-in-vein nerve grafts was significant bigger in comparison with the classical group (15%).The method using muscle-in-vein nerve graft with windows-vein it�s a good alternative for nerve grafting in comparison with classical nerve grafting. When the local possibilities are limited, this method is good for prolonging the grafts. The relationship between cost and benefit in this case it�s an advantage because we use the local resources of the affected area. The motor results of nerve grafting ingroup 2 in comparison with group 3 were similar and in some cases better in group 1. Grafting with MVNG offers a better alternative for donor site regeneration in comparison with classical nerve grafts. This method is useful to prolong nerve grafts without adding morbidity.

Lead Compounds

Background: It is one of the effective ways for pesticide innovation to develop new insecticides from natural products as lead compounds. Quinine, the main alkaloid in the bark of cinchona tree as well as in plants in the same genus, is recognized as a safe and potent botanical insecticide to many insects. The structural modification of quinine into 9R-acyloxyquinine derivatives is a potential approach for the development of novel insecticides, which showed more toxicity than quinine. However, there are no reports on the insecticidal activity of 9Racyloxyquinine derivatives to control Mythimna separata. Methods: Endeavor to discover biorational natural products-based insecticides, 20 novel 9Racyloxyquinine derivatives were prepared and assessed for their insecticidal activity against M. separata in vivo by the leaf-dipping method at 1 mg/mL. Results: Among all the compounds, especially derivatives 5i, 5k and 5t exhibited the best insecticidal activity with final mortality rates of 50.0%, 57.1%, and 53.6%, respectively. Conclusion: Overall, a free 9-hydroxyl group is not a prerequisite for insecticidal activity and C9- substitution is well tolerated; modification of out-ring double-bond is acceptable, and hydrogenation of double-bond enhances insecticidal activity; Quinine ring is essential and open of it is not acceptable. These preliminary results will pave the way for further modification of quinine in the development of potential new insecticides.
