This study consists of two stages of activities, namely the first population distribution mapping, nest study, disease, pathogens, interviews and discussions with residents regarding their perceptions and knowledge of Megapodius reinwardt, study documents regarding tourist visits; second, build awareness and participation of local residents to support the conservation activities of Megapodius reinwardt, formulate its conspiracy design and determine potential nests as tourist attractions. Perception of local residents on Moyo island to the existence of Megapodius reinwardt in fulfillment of the people needs directly or not directly. Local residents believe that by keeping Megapodius reinwardt will make the life needs can be fulfilled. In addition to that, residents of local island of Moyo assume that hunting the bird at the spawn period \" Mali \" or bring disrepute to hunters. Perceptionof the local residents of Moyo island to the preservation of Megapodius reinwardt most large 85% of the population agree to the preservation of Megapodius reinwardt on Moyo island, 10% are still in doubt, and 5% did not agree. The management effort of Megapodius reinwardt as one of the tourism attractions, should involve and be able to accommodate the needs of local people, tourists, businessmen of tourism and the government. For the success of the bird conservation efforts, it must pay attention to six things, namely: 1) agreement to recognize the minimum rights of group members; 2) clarity on the limits of the scope of mastery of each active community management group; 3) conformity between nest management costs and benefits obtained; 4) conflict resolution mechanisms; 5) firmness in applying sanctions and 6) willingness to receive knowledge / information and conservation technology and management of Megapodius reinwardt from outside Moyo Island.The research about distribution, species survival and conservation of Megapodius reinwardt based on ecological knowledge of local people to support ecotourism on Moyo island has been done.

In the early 1990s, mangrove was planted. The results show that a significant number of people who are directly dependent are those who are looking for shellfish, mangrove crabs, shrimp and fish as livelihoods. In addition, community groups that have indirect impacts are those who look for small shrimp in coastal waters as raw material for shrimp paste. In conclusion, the local scale mangrove conservation efforts can be a solution for the livelihoods of local communities. Therefore, a local scale conservation models can add or become a policy choice on a broader scale to maintain the existence of a mangrove ecological system for the environmental and economic needs of the community.Mangrove ecosystems are natural resources in coastal areas that have their own ecological systems, and have contributed as a place for local people to get their daily needs.

One effort to improve soil fertility and increase photosynthetic productivity in seeds is by adding phosphor and organic fertilizers. The indicator of increasing soybean crop production is derived from the amount of photosynthate accumulation in seeds. This study aims to investigate photosynthate accumulation and distribution on soybean crop (Anjasmoro variety, a well known soybean variety in Indonesia) at various dosages of phosphor and organic fertilizers during the vegetative and generative phase. The experiment was conducted in Sesela Village, West Lombok Regency, West Nusa Tenggara Province during the second dry season (August - November 2015). The experimental design was using a randomized block design with two factors. The first factor was phosphor with 4 dosage levels: 0 kg/ha, 36 kg/ha, 72 kg/ha and 108 kg/ha. The second factor was organic fertilizer with 4 dosage levels: 0 ton/ha, 2.5 tons/ha, 5 tons/ha and 7.5 tons/ha.

Hence, in this study we investigate the proposed mechanism of action of Wali seed suspensed and ethanolic extract trough measuring the glycogen content in liver and muscles and observing the pancreatic histology of diabetic rats. Wali seed extract (dose 20 and 30 mg/kg BW) and suspense (25 and 50 mg/kg BW) have comparable antidiabetic activity with glibenclamide. Treatments of Wali seed extract and suspense showed dramatically higher glycogen level both in liver and muscles than all controls. Treatment with glibenclamide and Wali seed extract and suspense the pancreas to normal architecture, regeneration of β-cell and enhanced morphology of the β- cells in the islets of Langerhans. The proposed mechanism of action of Wali seed extract and suspense is by converting blood glucose to glycogen storage trough glycogenesis and by recovering the islets of Langerhans of pancreas damage.Brucea javanica (L) Merr, locally called “Wali”, is a plant traditionally used to treat diabetes mellitus by local people in Lombok. The people daily consumed the seed to control the blood glucose into normal level. However, the mechanism of action of Wali seed as antidiabetic agent was still unclear. Hence, in this study we investigate the proposed mechanism of action of Wali seed suspensed and ethanolic extract trough measuring the glycogen content in liver and muscles and observing the pancreatic histology of diabetic rats. Wali seed extract (dose 20 and 30 mg/kg BW) and suspense (25 and 50 mg/kg BW) have comparable antidiabetic activity with glibenclamide. Treatments of Wali seed extract and suspense showed dramatically higher glycogen level both in liver and muscles than all controls. Treatment with glibenclamide and Wali seed extract and suspense the pancreas to normal architecture, regeneration of β-cell and enhanced morphology of the β- cells in the islets of Langerhans.
