Abstract

ABSTRACT Talawaan watershed is one of the most important watershed in North Minahasa Regency. Erossion in the Talawaan watershed results in decreasing land resource quality caused by both natural and human activities. This research aims to study the erosion hazard level in Talawaan watershed. Method to calculate erosion rate is based on USLE equation (Wischmeir and Smith, 1978) utilizing Geographic Information Systems (GIS). Result shows that the erossion hazard levels in Talawaan Watershed were “very light” 2.791,56 ha (21,49%), “light” 4.019,46 ha (30,94%), “medium” 3.127,86 ha (24,08%), “heavy” 2.521,79 ha (19,41%), and “very heavy” 528,88 ha (4,07%). Talawaan watershed has an average erosion rate of 60.53 tonnes/ha/year which is “medium” erosion hazard level. The results of this study may be used to a better management plan of Talawaan watershed. Keywords: TBE, GIS, USLE, DAS Talawaan.

Abstract

ABSTRACTCoconut plantation areas in Indonesia, specifically in North Sulawesi by the owners are tendto use monocultural pattern with only one product, copra. Efficiency in using growing spaceand certain planting pattern in form of agroforestry and its combination will give reciprocalbenefits, i.e. the cleanness of coconut planting area could be maintained with a possibility ofincreasing in coconut product, and economical benefits by utilizing of the unused growingspace on the lower space of coconut plantation area. If the economical benefits could bequantified, application of agroforestry pattern could be practiced to a wider area. Applicationof agroforestry pattern between coconut trees (Cocos nucifera) and taro (Colocasia esculentaL) by farmers who work on coconut plantation area is one of the agroforestry pattern that hasbeen used in Klabat Village, North Minahasa Regency. Lacking in knowledge of economicalvalue of the agroforestry pattern applied is a motivation why this reseach was done. Theaimed of this research was to analyze farming revenue based on agroforestry patternapplication between coconut and taro at Klabat Village, North Minahasa Regency.Questionnaire and interview were employed to collect required data and information using 30purposive respondents. This concluded that planting of both crops in combination resulted inhigher revenues than that of monocultural planting.Key words: agroforestry, Klabat village, farming revenue

ABSTRACTThis study aimed to determine the composition of the species and structure of mangrove forests in Sapa Village South Minahasa District. The study was conducted in October-November 2016. The Important Value Index (INP) obtained from vegetation analysis was used as an indicator to describe the composition and structure of mangrove forest. Plot assisted path method is used in vegetation analysis. Created 10 lane hayal with a width of 200 m divided into 10 segments, there are 69 plots to obtain data and species of mangroves. This study showed that 7 species from 4 mangrove families in Sapa Village, namely : Rhizophoraceae (Ceriops Tagal, Rhizophora mucronata, Rhizophora apiculata, Bruguiera gymnorhiza), Sonneratiaceae (Sonneratia alba), Avicenniaceae (Avicennia officinalis), Meliaceae (Xylocarpus granatum). Species with the highest INP values are Sonneratia alba at all growth rates, trees with INP values of 178.63%, stakes 101.14%, and 65.37% seedlings. The mangrove trees in Sapa village are found in a diameter range of 10 to 20 cm.Keywords : composition and structure vegetation, Sapa Village.

AbstractThis research aims to study the structure and composition of forest tree vegetation in the protected forests of Mount Mahawu and Mount Masarang. Line Method was used to study the changes in tree distribution based on the topography and elevation. Plots measuring 20 x 20 m2 are made following topographic lines (mountain slopes). The results show that the structure and composition of the dominant trees in the Mahawu Protection Forest are different from that of the Masarang Protection Forest. The dominant species in the Mahawu Protection Forest are Diospyros celebica, followed by Ficus septica and Anthocephalus chinensis; while in the Masarang Protected Forest Artocarpus sp. followed by Ficus septica and Lansium sp.Keywords: forest tree structure, forest tree composition, Mount Mahawu, Mount Masarang, protected forest
