Abstract

ABSTRACT This study purpose is to determine the potential and development strategies in the area of food crops in agropolite region of West Kawangkoan District. This research was conducted for three months starting from April 2015 until June 2015 in West Kawangkoan District.  To determine the potential of food crops in in West Kawangkoan District was analyzed descriptively and to analyze the development strategy of food crops in the agropolitan region in West Kawangkoan District the writer’s using SWOT analysis. The results of the study showed that the agropolitan region in West Kawangkoan District has the potential for planting corn and peanuts because it is supported by a good land, good infrastructure of buildings, roads, transportation, market, electricity and telecommunications to support agricultural activities and also industry partnerships with other agencies for the development of agropolitan. The strategies for food crops development  in Western Kawangkoan  the farmers are to utilize the resources and skills in managing food crops of corn and peanuts, to increase productivity of food crops by using the appropriate technology, maximizing of the processing industry to meet the demand of consumers, to establish good cooperation with the Government in doing mentoring and monitoring of the distribution of seeds, fertilizer and  agricultural tools/machineries from manufacturer up to the diluent, merchants, to farmers in order to make available in a timely manner, as well as enhance cooperation between farmers with processing industry and animal feed industry results in developing regions of the western Kawangkoan as an agropolitan area. This region was selected based on the results from a SWOT analysis which was located in the first cell of second quandran is an aggressive strategy, this strategy can spur growth and development of food crops especially maize and peanuts in district Kawangkoan.

Abstract

ABSTRACT  This research studied the effects of planting media on the growth of red Jabon (Anthocephalus macrophyllus (Havil) Roxb) seedlings. The objective was to determine the effect of several mixtures of soil, sand, and manure as a planting media for growing seedlings of red Jabon. The research was conducted in two months from April to July 2013, using a completely randomized design (CRD). There are 5 treatments of planting media, namely M1, M2, M3, M4, and M5. Each treatment has 5 replications and each replication was planted with one individual plant. Measured variables were plant height, trunk diameter and leaf number Analysis of variance was done and if there was a significantly different among treatments, a folowing LSD test was carried out. Increments of plant height were significantly different at 63 day after planting,(DAP) whereas increments of trunk diameter were significantly different at 49 DAP. Mixtures of soil, sand and manure showed significantly different effects, and adding sand to the soil with relatively high clay content (> 40%) was important to improve air and water circulation in planting media.

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. Keywords : River Roughness, Manning equation, Sario River
