Judul: Pendugaan Potensi Hutan Rakyat Menggunakan Citra Landsat 7 ETM+ di Kabupaten Ciamis Bagian Utara
Abstrak: Development of forest outside the forest area managed state today can be an alternative solution to the problem of forest resource pressures. One such alternative is the developed of private forest that are socially, economically, and ecologically profitable. Increased potential of timber forest product on private forest have significance in private forest management activities. Therefore, it is necessary to have an estimate of potential of research activities in private forest. The purpose of this research is to formulate a Estimation model of potential of private forest using Landsat 7 ETM+ imageries and create a map of distribution potential of private forest using Landsat 7 ETM+ imageries in north of Ciamis Regency. Stages of this research consisted of: preparation, image processing, field data collection, field data processing, modeling, and a map of distribution potential of private forest. The results of analysis shows the correlation between the value of NDVI with value of standing volume is high relatively (> 0,800), this case explains that the value NDVI on Landsat 7 ETM+ imageries can be used in surmise standing volume. Based on the results of the regression analysis and mapping accuracy test, selected models are used for mapping the distribution of potential of private forest in north of Ciamis Regency is the exponential models is V = 20,905*℮(1,765*NDVI) with R2 values of 62,8%, Kappa Accuracy of 30,9%, and the value of Overall Accuracy of 56%. Overall the location of villages surveyed are had a potency between 44,6 m3/ha up to 78,3 m3/ha with a total potential of private forest between 1.366,9 m3 up to 70.868,4 m3.

Judul: Pendugaan Potensi Tegakan Hutan di Sub DAS Cimuntur, DAS Citanduy, Kabupaten Ciamis, Jawa Barat.
Abstrak: Hutan memiliki peranan penting dalam pemenuhan kebutuhan manusia secara ekonomi, sosial dan lingkungan. Guna mendukung pemenuhan tersebut terhadap hasil hutan terutama kayu diperlukan informasi mengenai potensi hutan secara aktual. Tujuan dari penelitian ini yaitu mengidentifikasi tutupan lahan hutan menggunakan citra Landsat 8 (OLI) dan melakukan pendugaan potensi tegakan hutan di Sub DAS Cimuntur. Metode pengambilan data potensi tegakan dilakukan secara purposive sampling, sedangkan klasifikasi tutupan lahan dan analisis sebaran potensi hutan dilakukan melalui interpretasi visual. Hasil interpretasi visual citra Landsat 8 (OLI) menghasilkan 5 kelas tutupan lahan meliputi hutan tanaman, pemukiman, pertanian lahan kering campur (hutan rakyat), sawah, dan tubuh air. Hutan tanaman memiliki pendugaan potensi ratarata sebesar 347.85 m3/ha sedangkan hutan rakyat sebesar 201.63 m3/ha dan potensi total tegakan hutan di Sub DAS Cimuntur sebesar 214.35 m3/ha.
