ABSTRACT
The research is located in the Bungus Bay Waters Padang. The purpose of this study was to analyze the grain size and rate sedimentation of Coral Reefs and Seagrass. Bungus Bay Waters, including in the area of the Bungus District administration TelukKabung, located in the Southern part of the Padang City. The method used to analyze the grain size of sediment that is based on the scale of classification Wentworth- Udden, which sampling using the tool Sediment Grab, while the rate of sedimentation is done by using a Sediment Trap, in the form of Acrylic Tubes that is attached to the bottom waters and a Coral Reefs monitoring was conducted by LIT (Line Intercept Transect) and observations of Seagrass Ecosystems using transect method quadratic size of 1 x 1 m. The results showed high sedimentation in the Bungus Bay Waters with sedimentation rate with an average 400.58 - 1456.76 mg/cm2/day. This is significant impact on the growth of Coral Reefs and Seagrass. With the measurement results of the sedimentation rate in three streams indicating fairly high sedimentation in the Bungus Bay Waters. This incident could cover coral reefs ecosystem and seagrass in the area, but not so affect to the Mangrove Ecosystems. Thus in generally the sedimentation can damage the ecosystem in the Bungus Gulf Region.

ABSTRACT
Study of granular formulation of Bacillus sp. and Fluorescent pseudomonas to control the bacterial wilt disease on patchouli plant has been done. The aims of the study were to find out application time and effective concentration of formulation. Treatments were arranged in Randomized Block Design (RBD), factorial systems, five replications. The first factor are times of application: 1, 10 and 20 days after planting (DAP) and the second factor are concentrations: 0, 50, 75 and 100 g/plant. The assessment parameters were: incubation period of symptoms disease, disease intensity, height plant and number of leaves. The results showed that Granular formulation of Bacillus sp. and Fluorescent pseudomonad could control the bacterial wilt disease with delayed the incubation period of symptom disease from 14 DAP to 32,33–54,33 DAP and decrease disease intensity from 84,2% to 19,5-44,8%. Application of 1 and 20 DAP with concentration 75 and 100 g/plant is longest incubated period of symptom disease were 48,24–54,33 DAP, highest decrease disease intensity were 19,5–29,7%, increasing height of the highest plant from 22,1 cm to 42,8–48,3 cm and leaves numbers from 20,0 to 34,6–39,7 leaves/plant.

ABSTRACT
As one of important plantation commodity, rubber contributes to country income, economic growth and job creation. Increasing of the demand leads farmers to increase the productivity. Ironically rubber price is very low since it has low quality. This situation was occurred because of lack of awareness in quality insurance, hereditary conventional processing technique and inadequate processing machine. Some of characteristic of low quality rubber i.e. the dark color, number contamination level, stench, composition, etc. This research objectives was to improve quality of rubber production by using roller mill, dryer and natural coagulant, to gather information about rubber sheet and to analyze about rubber quality. so that the farmer could have an alternative method in rubber processing to increase value-added of productions and would give benefit to ground farming level. The conducted research showed that sheet rubber with twice grinding by using vinegar and liquid smoke as a coagulant produced a thickness of 5-7 millimeters. This is an ideal size for sheet rubber category. On the other hand, Although it slightly smell of smoke, the rubbers produced was not smelly compared to the conventional ones. in addition, average reduction of water content of the rubbers was about 18%.

ABSTRACT
The aim of this study were to know the role, perception dan analyse it by stakeholders analysis in the management of environmental services. This study used survey with in-depth interviews with key informants and snowball sampling method to interested parties. It also conducted a focus group for stakeholders to gather information on barriers and attempt to increase the utilization of environmental services in the indigenous forest for the improvement of people's welfare. There were eleven stakeholders were grouped into four quadrants (subject, players, crowd and the contest setter) according to the degree of importance and authority in the management of environmental services Forests Prohibition Indigenous of Rumbio. Primary stakeholders were indigenous institution, village, and water Enterpreneur.
