Abstract

This research was conducted in the protected forest area of the Tepo Asa Aroa Forest Management Unit (KPHL Unit XIII). This research was carried out by maximally comparing planning documents with actual conditions in the field, with the formulation of existing problems, namely to see whether the management plan is based on the criteria for protected forest utilization. which is in the regulation of the director general of forestry planology P.5/VII-WP3H/2012 is in accordance with the implementation in the field. Based on the results of research collected in the field and related agencies, explained that the protected forest utilization block located in the Protection Forest Management Unit (KPHL) Tepo Asa Aroa has the highest area in 94 management plots, and there is the potential for non-timber forest products such as rattan and dammar and environmental services in the form of waterfalls. The suitability of the management plan refers to the criteria, but implementation in the field has not been fully implemented.Keywords : Protection Forest, Planning Management, Forest Management Unit

Abstract

The Miu sub-watershed has a strategic function in providing ground water. Various community activities around the Miu sub-watershed have made its condition increasingly degraded which is quite serious in terms of its ecological, economic and social functions. As an initial step to maintain conservation, it is necessary to do land use in the Miu sub-watershed. This study aims to determine the type of land use found in the Miu sub-watershed and to determine the type of composite tape that is good for interpreting land. This research was carried out by conducting a composite image which was then carried out by taking training samples (sampling) then conducting a guided classification (supervised classification) and checking in the field and the last step was to test the accuracy of image accuracy. From the results of Landsat 8 image classification using composite band 632 obtained 6 land use classes and composite band 654 and band 653 obtained 7 land use classes consisting of Primary Forest, Secondary Forest, Plantation, Shrub, Settlements, Open Land, and Water Bodies. Meanwhile, from the results of the accuracy test using the Confusion Matrix method, the security band 654 has the highest level of accuracy with a total accuracy value of 85%, compared to composite band 653 which has an accuracy value of 74% and band 632 has an accuracy of 63%.Keywords: Landsat 8 imagery, classification, use, Miu . sub-watershed

Abstract

This study attempted to develop an extraction model of spectral values ​​of land objects into land use/land cover classes on remote sensing image in the provision of land database for planning, evaluation, and monitoring in agriculture and forestry. This study employed an Isodata method and Knowledge-Based Systems (KBS) using the Landsat 7 ETM+ image in the coverage area of ​​117,799.06 ha, and the SPOT 5 XS image in the coverage area of ​​113,241.37 ha in Palu, Sigi and Donggala. The study found two image models labelled as AR4-50 and SBP-AR4-50. The separability image AR4-50 model has an average capability for separating land object pixels which are statistically 1811.98 to 1972.08 (moderate-good), with the class accuracy of land use/land cover using the image homogeneity model of SBP-AR4-50, which is totally (confusion matrix) 72.15% -87.17%, the accuracy level of land map generator for agricultural land/forestry is in good-excellent category on the Landsat 7 ETM+ and SPOT 5 XS images. Keywords: Image, Class, Land Use, Model, Separability, Homogeneity.

Abstract

Forest encroachment and both of its complexity and implication is a problem that faced not only an area/region but also all forest areas in the country,  so that the encroachment has been a national scale problem that supposed to have serious attention  especially to overcome it. Natural disaster such as flood, landslide that always happened in rainy season and often cause hundreds of unguilty victim. The research was to find out the result of interpretation and the width of protected forest encroachment, South Dolo Subdistrict Sigi Dictrict. The research applied supervised classification and NDVI (Normalized Difference Vegetation Index) analysis. The analysis used in the research was managing image digitally that used for image correcting, image band compositing, image cutting, image sharpening and clarifying. Based on the research it was found that the clarification result of land covering consisted of primary forest, secondary forest, opened lang, plantation and settlement. The map of land covering for the research had the accuracy level of 86%, meant that the map for the research fulfilled the standart of carefulness interpretation and very good for seeing the class of land covering type in protected forest of  South Dolo Subdistrict Sigi District. The area of Protected Forest in South Dolo Subdistrict had density level with interval vegetation Index (NDVI) from -0,58 to  0.07 with 966,50 width or 100 % percentage. The result of scoring count showed that the result of NDVI with rare criteria was -0,58- 0,07 and the land use that consisted of forest with width of  26.947,79 ha (93,04 %) and encroachment rate of 180 and in the category of fair encroachment level, good managed land in width of 3.92,99 ha (1,35%)  encroachment rate 240 with high encroachment level, and bad managed land with widht of  1.625,72ha (5,61 %) and encroachment rate of 300 was in the level of high encroachment, therefore the total width was 28.966,50 ha (100%).Keywords:  Encroachment, Protected Forest, NDVI.

Abstract

Degradasi lahan yang berakibat rendahnya produktivitas lahan merupakan masalah serius di Desa Tuva Kecamatan Gumbasa Kabupaten Sigi. Salah satu masalah yang serius yang perlu ditangani adalah meminimalisir tingkat kerusakan tanah pada bagian atas topsoil nutrisi tanah dan erosi. Tujuan kegiatan pengabdian ini adalah pendidikan dan pelatihan/bimbingan teknis peningkatan produktivitas lahan melalui aplikasi biochar, pembuatan tanaman berupa pengembangann agroforestri. Metode pelaksanaan menggunakan metode pendidikan dan pelatihan bersifat partisipatif atau educational and participatory approach. Proses penyuluhan/pelatihan dilaksanakan melalui pendekatan Focus Group Discussion dan Participatory Rural Appraisal. Pendekatan yang dilakukan dalam kegiatan gelar teknologi ini adalah pendekatan learning by doing melalui demonstrasi plot, dimana petani dilibatkan secara langsung, sehingga terjadi pembelajaran secara langsung di lahan petani. Metode ini akan memposisikan masyarakat sasaran, sebagai mitra dalam hal penerima pengetahuan, pemahaman dan keterampilan, dimana mereka akan terlibat dari awal sampai berakhirnya kegiatan Pengabdian termasuk evaluasi. Hasil dari kegiatan pengabdian yang dilakukan telah terlaksana: (1) aplikasi demplot pembuatan biochar, pupuk kompos fermentasi dan kompos konvensional; (2) aplikasi demplot pembuatan tanaman melalui sistem agroforestri. Kerjasama antara lembaga atau institusi lain sebagai mitra dalam pelaksanaan program penerapan pengabdian diperlukan untuk keberlanjutan program yang sudah ada
