Abstract

ABSTRACTThe purpose of this study was to analyze the landslide prone areas in Sub Watershed of Tondano in order to obtain the vulnerability information and dissemination in the form of map by using the Geographic Information Systems. The study was conducted by using a Descriptive Method which consisted of a survey and map overlay, while the identification of areas prone to landslides using the scoring method. Parameters measured were soil type , slope , elevation , land use and rainfall . The results showed that the spread of landslide-prone areas in the Sub Watershed of Tondano consisted of five classes of landslide susceptibility, namely (1) No class landslide prone area of 993.12 ha, or 23.64%, spread over an area of 137.42 ha districts Eris, Kakas of 1.31 ha and 854.39 ha area of East Tondano; (2) The low vulnerability class area of 207.59 ha, or 4.94%, spread over an area of 144.10 ha district of Eris, Kakas area of 0.29 ha and 63.20 ha area of East Tondano; (3) Moderate impact class area of 894.19 ha, or 21.28% spread over an area of 503.06 ha district of Eris, Kakas area of 114.97 ha and 276.16 ha area of East Tondano; (4) High vulnerability class area of 469.23 ha, or 11.17% spread over an area of 256.27 ha district of Eris, Kakas area of 48.03 ha and 164.93 ha area of East Tondano; (5) Highest area of 1637.23 ha or 38.97% spread over area of 455.60 ha district of Eris, Kakas area of 45.46 ha and 1136.17 ha area of East Tondano.Key Words : Mapping, Landslide, Sub Watershed of Tondano, GIS (Geographic Information System)

Abstract

AbstractWori districts which has an area of 90.704 km2 is one of North Minahasa district that processed into oil palm plantations, coconut flour, nata de coco, coconut shell charcoal and coconut trees. Coconut flour is one of the oil derivative products (integrated coconut) recorded the many buyers and scattered in almost all parts of the world. Buyers of coconut flour was more focused on Eastern Europe, but is now rapidly spreading evenly over all the continents in the world. Anticipate in terms of availability of coconut flour it is necessary to the development of the coconut crop, given the current availability of old coconuts began to decrease. This study aims to determine the potential of land for coconut (Cocos nucifera L) in District Wori North Minahasa regency. This research can provide input and information to the government and the people of North Minahasa district Wori in coconut planting efforts. The research was conducted in the District of North Minahasa regency Wori, and in Laboratory Soil Department of Faculty of Agriculture, University of Sam Ratulangi Manado. This study was conducted in July 2009 and September 2011. Research methods implemented by way of a survey method with land unit approach, the observed variable is the slope, effective depth, texture, erosion, drainage, soil type and land use. The data were then arranged in tabular form later described descriptive to determine appropriate land or potentially and inappropriate or potentially for coconut by coconut trees growing conditions The results showed that in the region have Wori climate types B1, namely: 7-9 wet months and <2 dry months. Wori altitude region is 0-610 meters above sea level with the form region is rather flat, undulating to mountainous. Slopes in the study area is dominated by slopes <15%. Wori soil characteristics in the area, where the physical and chemical properties of the soil, namely: effective depth, texture and drainage and soil pH, indicating that the soil in the area has the potential to Wori Based on comparison of coconut and palm trees growing conditions with the conditions of the study area Wori region potential for development of coconut plantations with a total area of 4637.80 ha

Abstract

ABSTRACTThe type of soil in the research site is Andisol soil with clay texture. The Andisol soil characteristics is a dark color / black, gray, dark brown to yellowish. The soil derived from volcanic ashes from the eruption of the volcano. Therefore, this type of soil are found in the area around the volcano's slopes. Like the soil in this research is located on the slopes of Mount Mahawu. Although it has many advantages, but the ground Andisol also has many disadvantages. Andisol ground weakness is due to the loose structure and crumbly, the type of soil is very easy take by rainwater. Therefore, in this research, land conservation efforts in the form of plastic mulching. In this study the use of plastic mulch as a treatment, more soil erosion results in the use of plastic mulch plots compared to not using plastic mulch. This is due to the use of plastic mulch, most of the rain water does not infiltrated into the ground because it was blocked by the plastic mulch, causing greater runoff. Large land runoff causes soil erosion more bigger easily transported.Keywords : Erosion, Soil Conservation Technique, Holticulture, Carrot (Daucus carrota L.)

Abstract

ABSTRACTThis study aimed to know physical land suitability for soybean crops in the Pandu Village, Mapanget District of Manado. This research can provide input and information to the government and the people of the district of Mapanget about land suitability, especially for soybean plants, which were held at Pandu Village, Mapanget District of Manado city, and at the Laboratory of Soil Conservation and Physics, Faculty of Agriculture of Unsrat for 6 ( six ) months, commencing from March to August 2013, by using the method of Land Survey Unit Approach. The results showed that, the agricultural land at Pandu Village has some potential areas for development of soybean plants. Area I and VI were categorized into suitability classes S2 ( quite appropriate ), Area II was the suitability class S3 ( marginally suitable ), Area III was suitability class N1 ( not appropriate at this time ), Area IV were conformity classes N2 ( not appropriate forever )Keyword: Physical Land Suitability, Soybean
