Abstract

ABSTRACT  This study aims to (1) Description the level of socio-economic support for land rehabilitation and soil conservation around the upstream watershed Ranoyapo, (2) analyze the socio-economic factors  and affect the support of farmers on land rehabilitation and soil conservation in the watershed upstream Ranoyapo Minahasa south. This research was conducted in the village of the District Mopolo Ranoyapo, Karowa village and sub-district Toraut New Tompaso and villages Mokobang Modoinding District of South Minahasa District. The variables were observed in this study is the level of support and socio- economic factors that have a relationship and affect support for land rehabilitation and soil conservation.  The techniques of data collection will be done is prasurvey, the initial data collection in order to draft the research proposal. For variable rate of economic and social support relationship socioeconomic factors that affect the support classes were analyzed by assigning weights of 1 to 5 for each answer choice that is in the questionnaire. Total weight of all the answers to the questions will give a classification of the level of support each respondent farmers based on criteria of value support. Furthermore, the relationship socioeconomic factors that affect the support analyzed by non parameterik statistical approach that analyzes Pearson Product Moment assisted with SPSS applications. 3   The results showed the level of socio-economic support in land rehabilitation and soil conservation in the watershed upstream Ranoyapo strong and very powerful. For relationship socioeconomic factors that affect the level of support proved that the age factor of respondents have a relationship or positively correlated with support for land rehabilitation and soil conservation.. Education factor has no significant relationship to the socio-economic support in land rehabilitation and soil conservation. Results of this study resulted in several conclusions, namely: (1) The level of social support for the local economy in land rehabilitation and soil conservation in the watershed upstream Ranoyapo strong and very strong so the chances of success will be achieved. (2). Factor respondent's age has any relationship or positively correlated with support for land rehabilitation and soil conservation in the watershed upstream Ranoyapo whereas education and the status of the land factor not related or correlated with support for land rehabilitation and soil conservation.

Abstract

ABSTRACT Analysis of River Roughness Coefficient in Sario River with Manning Equation Sario river is the main river of Sario Watershed.  Due to rapidly increasing population, protected area alongside river border had become settlement.  This causes a decrease of river channel capacity so that flood could happen as a case in January 2014.  Manning equation is the formula frequently used to calculate the flow capacity of open channel. The purpose of this research is to determine roughness coefficient of Sario River by using Manning equation. This research was done in three months starting from January 2015 to March 2015.  Observed and measured variables were river width, top width, bottom width, water depth, river channel depth, river pseudosection profile, flow velocity, gradient of bottom channel, and channel description.  Method applied was survey method and the determination of measurement and observation points was done with certain consideration (purposive sampling).  The averages of calculated roughness coefficients of Sario River are 0,049 for upstream, 0,050 for middlestream, and 0,060 for downsrtream. The average of Sario River roughness coefficient is 0,048.  Garbage and water countaining dispersed particles caused roughness coefficient greater than secondary data for natural channel.

Abstract

ABSTRACT Marawas is one of the most important watershed in  Tondano watershed in Minahasa. The erosion that happens at  Marawas watershed caused by land change and human activity. This study helps us to analyze the erosion risk levels  in  Marawas watershed. Field survey was to document land cover, slope length, slope depth. The erosion risk Level were determined by USLE (R,K,L,S,CP). The study shows that the erosion risk levels of Marawas watershed are very light (62.5924 ha, 51,09%), light (0.7397 ha, 0,6%), middle (0.7397 ha, 0,6%), heavy (0 ha 0%) and very heavy (0,2792 ha, 0,23%). Marawas watershed hasthe average of erosion’s rate of 49.45 tonnes/ha/year or light level of Light erosion risk.

Abstract

ABSTRACT The research aims to determine the population and attacks Cnaphalocrocis medinalis on paddy rice vegetative phase in District East Dumoga, Bolaang Mongondow. Results are expected to be used as consideration in the preparation of pest control strategies C. medinalis on rice crops in the future. Research using survey method in several centers of rice cultivation in the district of East Dumoga Bolaang Mongondow, then set the 3 villages as research locations or as a sampling. Location criteria based on the presence of the rice research under the age of one week. Sampling using Method Diagonal slices and set up five sub-plot. Observations population conducted by randomly selecting ten clump of rice plants in each sub-plot. C. medinalis larvae contained in the leaf roll is taken, and then collected in a bottle containing 70% alcohol. Samples are labeled according to location and time of uptake, later identified in the Laboratory of Entomology and Pest Plants, Faculty of Agriculture, University of Sam Ratulangi. Observations percentage of attacks carried out by observing each of the 200 plants per sub-plot. Clumps were attacked recorded and calculated to determine the percentage of C. medinalis attack. Sampling was performed four times at intervals of two weeks. The results showed that the population of pests C. medinalis varies at different locations and the highest research found in two locations in the village Dumoga which reached an average of 15.33 tail, then in the village Dumoga Three reached an average of 13.66 tail and in the village of Dumoga Four reached an average of 5.33 birds. Observations highest percentage of attacks was found in the village of Dumoga Two sample sites, reaching 10.54%, then the village of Three Dumoga 9.95% and the lowest is Village Dumoga Four reached 1.53%.  Keywords : Cnaphalocrosis medinalis, percentage of attacks and populations

Abstract

ABSTRACT  Food diversification is necessary of food development, and breadfruit is able to develop into a variety of food products. Breadfruit contains pretty high carbohydrate that 28.2gr/100gr mature flesh (Fao, 1972 in Gardjito etc 2013), which is very potential to be develop as an alternative to wheat flour in making of varieties of noodle such as fresh noodle. The aim of this research is to get the right formulation of breadfruit flour and pumpkin flour in making of wet noodle, and also to analyze the physical, chemical and sensory quality. The result of this research showed that the best and the dominant formulation is the formula C (80% breadfruit flour and 20% pumpkin flour) which is the most likeable formula. Formula C (80% breadfruit flour and 20% pumpkin flour) contains 25.19% of moisture content, 5,87% of proteins, 0.72% of ash, 32.33 sec of cooking time, 34.67 mins of cooking resistant. The sensory test’s of formula C showed that formula C is acceptable in panelists with scores; 3.46 of color, 3.42 of aroma and 4.08 of taste.  Keyword : Breadfruit, Pumpkin, Noodle
