ABSTRACT

Fish production in Nagari Guguak Malalo that was one of the main sources of community income declined. This impacts local economy, as a consequence, local people begun to intensify agroforestry to meet their needs.There is an indication of shifting in economic activities from wild fisheries to agroforestry. The aim of this research is to analyze the ratio of income contribution of agroforestry and wild fisheries bilih fish on household income. The research used  a case study method. The sample consisted of 40 households were selected randomly. Income from agroforestry and wild fisheries bilih fish were calculated by subtracting the total revenue of each activity  with the direct costs while household income is calculated from household annual expenditure. The results showed that agroforestry has been able  contribute for  8.78%  of  the household  income,  while the wild fisheries bilih fish business 45.37%. Nevertheless, there is possibility of agroforestryto replace wild fisheries bilih fish in the future, because agroforestry’s contribution showed an enhancement if people do agroforestry intensification. The finding suggests there is a need by the community to make decisions and choose the source of income, it also suggest that the government to issue agroforestry base development program in Guguak Malalo village.

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%.
