PELIBATAN MASYARAKAT DALAM KEGIATAN KEBUN BIBIT RAKYAT (KBR) DI DESA SOLONSA KECAMATAN WITA PONDA KABUPATEN MOROWALI
Get PDFForest condition in the Solonsa village, Wita Ponda district, Morowali regency and surrounding it is quite alarming nowadays. The damage that causes flood, droughts and landslides are the main factors that triggered the criticality and land degradation in some rural areas of Solonsa. The damage can be rehabilitated by involving the community to participate in a forestry program, in this case, the activity to make people’s nurseries (KBR). The program is devoted to the manufacture enrichment plant reforestation in Solonsa village. This research aimed at finding the community involvement in the activities of the people’s nurseries. This results are expected to be a useful written input to the government and non-governmental organization to carry out the nurseries program activities. The experimental method used in this research. This method is used in solving the problem by exploring the causal relationship of two or more variables through accurate experimentation. Software statistical program for social science (SPSS) used for the easiness data management and provisioning. The results show that the correlation between internal factors and community involvement, in relation to the age factor with the (0,266), education (0,056), the number of dependents (0,182), revenue (-0,163) was low toward the people’s nurseries activity.

ANALISIS TEMPORAL PERUBAHAN LAHAN HUTAN MANGROVE DI KECAMATAN BALINGGI KABUPATEN PARIGI MOUTONG
Get PDFDevelopment are the processes of land conversion for community needs of infrastructure and facilities that required for development of a region. In the process, there are land diversions that cost the value of land ecologic. It was replaced by economic function of mangrove. Moreover, in every month and year, in Balinggi district, mangrove forest is became embankment area. This research aims at finding out the change of mangrove’s area which happened since 2005 until 2013 in Balinggi district. The research was conducted in Balinggi district, Parigi Moutong regency on the area of mangrove. It was done in three months, from May to August 2014. The researcher used data of Landsat 7 ETM+ (acquisition 2005) and Landsat 8 (acquisition 2013) to support his data. Data Landsat was analyzed by using AcrGIS 10.0 software with some steps. They are Geometric correction and radiometric; interpretation and classification (supervised classification); and NDVI (Normalized Difference Vegetation Index) analysis. In 2005, the extensive of mangrove’s land was 609.47 Ha, then became 524,15 Ha in 2013. The area decreased about 85.47 Ha. Moreover, the result of NDVI showed that there were changes of mangrove land in 2013. From all the mangrove area in Balinggi district, its density was categorized into three levels. They were lush (265.75 Ha/2.38%), medium (79.21 Ha/ 17.31%), and rare (178.19 ha/33.99%). Keywords : Mangrove, Balinggi, Vegetatioin Index, NDVI, Landsat
KARAKTERISTIK HUTAN MANGROVE DI DESA BOLOBUNGKANG KECAMATAN LOBU KABUPATEN BANGGAI
Get PDFMangrove forest is one of unique forest ecosystem form which brings land and sea territory. Mangrove forest has specific characters in tidal areas, coastal marine zone and Small Islands in Bolobungkang village, Luwuk-Banggai of Central Sulawesi Province. The study aimed to edetermine Mangrove forest characteristic. Plot is used as the methodology which is placed into a strip with size 10m x 10m for tree level, 5m x 5m for stake level and 2m x 2m for seedling level which set into 20 strip plots along 2 strips. The sampling used is soil sampling which is conducted in aqueous (forward) and in near land area (back). The characteristics of Mangrove forest habitat in Bolobungkang village are loam, sandy loam and dusty loam. The PH ranges 3. 9 – 3. 0 and salinity ranges 2, 73 – 2, 69 per mile. The highest INP for the tree and the stake level is Rhizophora mucronatawith with the value of 116, 86 % and 125, 22 % while the highest of SDR is Rhizophora apiculata with a value of 93, 94 %.

PERTUMBUHAN TANAMAN EBONI (Diospyros celebica Bakh) PADA BERBAGAI NAUNGAN
Get PDFEbony (Diospyros celebica Bakh.) is a luxirious wood that very popular either in or abroad. The regeneration level of ebony in nature is low enough, it is caused of its semitolerant characterictic and its slowly growth,which on its seedling level, ebony needs shelter plants and at the time of secondary branch formed, it needs light intensity that should increase along its growth. The aim of the research was to find out the growth of Ebony plant in various shelter. The allocation time was began on May to August 2015. The research used Group Randomized design that consisted of 4 treatments and 2 groups as follow: slope tilt 50and 40, so there were 8 unit of trials. One unit of trial consisted of 5 seedling that the total planted was 4 × 2 × 5 = 40 seedling. The result of the research showed that shelter treatment of 90% (N4) resulted the increase of the highest number of Ebony seedling leaves was (`2,7sheets) and the smallest 0% (N1) as (0,02 sheet),the shelter treatment of (70% (N3) gave a better response to the height increase of ebony seedling was (1,01 cm) and the lowest 0% (N1) was (0,09 cm), and the width of ebony seedling leaves was (25,39 cm2) and the lowest 0% (N1) was (0,79 cm2), and the shelter treatment of 40% (N2)gave a better reponse to the diameter increase of ebony stem seedling was (0,35 mm) and the lowest of 0% (N1) was (0,02 mm).Keywords : Ebony, Diospyros celebica Bakh,Shelter, Growth
SIFAT FISIK TANAH PADA HUTAN TANAMAN KEMIRI, LAHAN AGROFORESTRI DAN LAHAN HUTAN SEKUNDER DI DESA LABUAN KUNGGUMA KABUPATEN DONGGALA SULAWESI TENGAH
Get PDFThe aim of this research was to find the physical characters of the soil in candlenut forest, agroforestry and secondary forest area at Labuan village Kungguma Donggala District of Central Sulawesi. This research was begun from location orientation, deciding three swath spots which were: candlenut forest, agroforestry area (teak and cocoa) and secondary forest. In deciding the location, purposive sampling was applied. From three locations, 5 samples of soil were taken so that there were 15 samples of soil taken. From five soil samples of one sample location were composed into one soil sample for next three soil samples analyzed in Geology laboratory. The result of the research showed that the conversion of the secondary forest into agroforestry and candlenut forest could reduce the physical characters of the soil (permeability, porosity, Bluk density, and organic material of the soil). Besides that, the texture of the soil in candlenut forest, agroforestry and secondary forest were different; they were sandy clay, dusty clay and clay.Kata Kunci: Physical properties, Candlenut, Secondary Forest, Agroforestr

STUDI KOMPOSISI DAN POTENSI VEGETASI HUTAN PRODUKSI DI WILAYAH KPHP MODEL DAMPELAS TINOMBO DESA LEMBAH MUKTI KECAMATAN DAMPELAS KABUPATEN DONGGALA
Get PDFForests play an important role in supporting the survival of life of living creatures, especially human beings, forests do not only provide immediate benefits as a source of forest timber and non-timber forest but also provide indirect benefits as a regulator of water management, soil fertility, erosion control, and landslides. So the existence must be maintained through regulation functions of forests. Therefore, KPHP is an institution that is closely related to the setting function of the forest. Forest production in the region KPHP Dampelas – Tinombo as the territory of Lembah Mukti village that damage has an area of about 735 hectares, therefore, requires a basic data about the composition and the potential production forest in Lembah Mukti village of using planning, management of forests and development of plantation forests. The research was conducted for 3 months starting from June to September 2014, in a production forest in Lembah Mukti village. The aims of research to determined the composition and potential vegetation in forest production. This research uses purposive sampling line continue, with the number of observation plots as much as 30 plots with a size of 20 m x 20 m. Production forest composition Lembah Mukti village consists of 25 types of vegetation, at the level of the tree in the plot as many as 169 individuals from 20 types of vegetation, while poles as many as 102 individuals of 14 species and seedlings stage as many as 73 individuals from 10 types of vegetation. Volume tree in the plot observations as much as 164,13 m3 of 169 individuals, the type of Tapi – tapi (Haplolobus cellebicus) has the most volume with 51,22 m3 and the volume level of the pole inside the plot observations as much as 15,71 m3 of 126 individuals, Jabon types (Anthocepalus cadamba) has the highest volume with 4,13 m3.Keywords : Composition studies, Potential vegetation, Forest production
