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.

ABSTRACT

The increasing of wheat consumption is necessary to considerthe local food materials as substitution material. Sago is the potential local food  that used as alternative material and rich of carbohydrate. This material can be used as substitution material of wheat in the making of noodles. However, the right amount of sago as substitution material of wheat in the making of noodle is unknowns.The purpose of study was to obtain the right amount of sago flour as substitution material of wheat in the making of noodle. The study was conducted on 6 percentages of sagoflour  as substitution of wheat (0%, 10%, 20%, 30%, 40% and 50% of sago flour). The best percentage was determined based on quality of noodle by using organoleptic test. The results show that addition 40% of sago flour was the best percentageas substitution material of wheat in the making of noodle. On this amount, the noodle had a good taste, color, aroma, and texture. From the proximate analysis, the noodles with 40% of sago also had a good value in water content, ash, protein, fat, carbohydrate, and less in micro-bacterial content.

Keywords: noodle, substitution, sago, wheat
