Abstract

ABSTRACT The objective of this research is to map the potential of wetland in Ratahan District by using Geographic Information System. This research used Information System uses descriptive method that consists of survey in field and the overlay of map. This research implemented in the Ratahan District used Citra satellite and physical observations in the field to see the areas that have the potential in wetland with the help of a 5 point coordinate. Mapmaking conducted at the Laboratory of Remote Sensing and GIS Soil Department, Faculty of Agriculture, University of Sam Ratulangi for two months (February-March) The potential of wetland in Ratahan District covering 6216.73 ha comprising: The potential of wetland on the slope of 0-8% covering an area of 5,850 ha, which is in the conversion of land use people's plantation area of 4467.00 ha, shrubs covering 448.00 ha, moor area of 444.00 ha and use of wetland is currently an area of 451.00 ha. The potential spread of paddy fields in Maulit village, Poniki village, Rasi village, Wioi village, Ratahan village, Pangu village, Tosiraya village, Vice Mayor village and Vice Mayor Pasan village. The potential of wetland at slope > 8% area of 366.73 ha is in the conversion of land use people's plantation area of 191.81 ha and use of wetland currently 174.92 ha. The potential of wetland in Kalatin spread in the village, and Lowu village. Keywords: Wetland, Geographic Information System.

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

Abstract This study aims to determine the characteristics of the estuary Malalayang which have an impact on the floodplain. This research was conducted by using the method of identification by viewing the variables that affect observations floodplain. Characteristics estuaries studied the nature of the estuary of the river, the water discharge, water quality, sedimentation and tidal. How to get the data through (1) Software ArcView to calculate the slope of the river and see Malalayang watershed flow patterns, the high point seen in RBI Map Scale 1: 50,000 Sheet 2417-23. Elevation Map / Contour Manado City used to look bathymetry of the estuary Malalayang. (2) Water discharge is obtained by the equation Q = V.A. (3) Water Quality visits with Tracer tool Pocketester pH, TDS and Salt. (4) The precipitation data obtained from BMKG Kayuwatu. (5) Data obtained from sediment trap sediment. The results showed that the characteristics of estuary Malalayang impact on floodplain: (1) the type tidal estuary leaning daily Malalayang dual pairs occur more frequently so that the deposition of sediment is more going on than spending sediments to the sea (sediment volume measured during the first month ie 294 372 cm3). (2) The pattern of flow in the watershed Malalayang is a dendritic pattern so that the discharge of water from upstream and water at high tide in the estuary can be restrained so that when the estuary Malalayang no longer able to accommodate the volume of water, then an overflow into the floodplain. (3) Bathymetry Coastal Estuary Malalayang Malalayang which is at a steep conditions.  Keywords: Estuary, Tidal, Sediment, Bathymetry

Abstract

The important function must be paid attention in waste management is landfill. At the location, the collected waste must be isolated well for not making new problem for surrounding environment. The existing of appropriate landfill location plan can minimize waste impact. This research was conducted at Sumompo landfill waste area of Manado Town by using survey method. Analysis variable of bio-geophysical referenced to SNI 03-3241-1991 adjusting SNI 03-324–1994 and was conducted standardization by dividing suitableness class of land is very suitable (good category), suitable enough (middle category), and less suitable (poor category). Analysis of social condition was conducted by viewing various response respondent level for existence of landfill location, then it was conducted standardization with dividing people response level become positive, neutral and negative. The result research, adequacy level of waste landfill Manado town in measurement of mitigation plan for landfill location is categorized suitable enough (middle category). The assessment is based on geophysical land review including suitable enough (middle category). The assessment was based on geophysical review of land including suitableness class II. For people encouragement was based on indicator of landfill existence, in neutral tend to positive (neutral category by Mahawu and Buha accepting by Tumintang, Sumompo, and waste collector).

Abstract

ABSTRACT The purpose of this study was to determine the effect of compost on land mined gold and knowing which one is the best type of compost to the early growth of the plant jackfruit. This research used Completely Randomized Design (CRD) factorial with 2 faktoral namely Factor A: types of compost with three levels while the B factors and three levels of fertilization and repeated 3 times so have 27 pot experiment. The results composting on mined land can improve soil chemical properties in this case the addition of the nutrients N, P, K and C-organic. Nutrient content of compost can be seen that the highest N content contained in compostable materials made of peanuts is 0.8%. While the highest available P in compost bins gamal is 16.79 ppm, the highest available K in compost market is 55.3 ppm and C-gamal organic compost is the highest at 9.11%. Jackfruit plant growth height and number of leaves both the best in the mined soil compost bins given market.
