Abstract

Forest resource plays  an important role  for human life in the various aspects: socio-economy, ecology and culture. This study evaluated socio-economic condition of people around forest which affected their preferences towards the level of intensity and quantity of forest utilization. Interviews was conducted by purposive sampling during March−May 2007, focusing to the forest community in RPH Sumberwaru and RPH Sumberejo, BKPH Asembagus KPH North Banyuwangi. Most respondents  were  low educated-farmer  that  utilized various forest products such as  firewood, grasses,  honey, seeds (Acacia  nilotica, Parkia roxburgii, Aleurites moluccana)  and honey. Through this study it was revealed that total value of forest products contributed to the local community was Rp 623,044,602 annually.  Two most valuable forest products for local community were grasses and firewood.  Grasses for fodder contributed to 60.89% and firewood was 25.53% of the total value. Totally, forest products contributed to 25.50% and 24.80%  to the total income of respondents in Sumberwaru and Sumberanyar village, respectively.Keywords: forest resource utilization, socio-economy, forest community, forest products

Abstract

Kebijakan desentralisasi atau yang umum dikenal dengan istilah otonomi daerah mengamanatkan kepada pusat untuk menyerahkan berbagai kewenangan pemerintahan kepadadaerah. Penyerahan kewenangan kepada daerah ini dimaksudkan agar tata pemerintahan dan pelayanan publik dapat berjalan secara lebih efektif dan efisien. Namun, peralihan sistem pemerintahan dari sentralisasi ke desentralisasi tidak selamanya berjalan lurus mulus. Ketegangan hubungan pusat dan daerah terjadi akibat keengganan penyelenggara pemerintahan di tingkat pusatmenyerahkan kewenangan kepada daerah dan egoisme kedaerahan yang berlebihan ditandai dengan terbitnya berbagai Peraturan Daerah yang bertentangan dengan peraturan di atasnya. Hal ini mengakibatkan ketidakpastian hukum yang berpotensi memicu konflik antara pusat dan daerah serta antara kelompok masyarakat menyangkut hak mereka untuk mendapatkan manfaat, akses dan tanggung jawab atas sumber daya alam termasuk hutan

Abstract

Private owned forest in Java already exists for decades. It was initially targeted for their own consumption. Studies by Faculty of Forestry of IPB in 1976 and UGM in 1977 revealed that70% of construction timber and 90% of fuelwood was supplied by private owned forest. Since then, much attention has been paid to private owned forests in terms of forestry policy, and those privateowned forests started growing into private owned timber business (POTB) along with the growth ofits market. The POTB involved many parties, where the private owned forest farmers is the main player in the business system but has not got optimum benefit. Beside that, in the whole, theperformance of POTB system has not yet been optimal, hence strategic bussiness need to be developed. The main objective of this study was to determine POTB structural model as component in developing the business. Hence, the study used Interpretative Structural Modeling (ISM) method.The structure of POTB development system consisted of 9 elements and 86 sub elements where most of the sub elements is included in sector III, meaning there is structural problem on the whole elements. Hence, the problem will need to be solved simultaneously to develop healthy business system. In the implementation of POTB development system, it was suggested that government has to make priority of development target, based on the analysis result of the systemstructure.

Abstract

Along with the concept of poverty alleviation and forest sustainability, forestry employment is the major concern among policy makers. The forest sustainability and job availability are critical indicators for the performance of the government. The relationship between employment and forestry development is unclear especially when it deals with illegal forestry activities. This study aims at generating projection of the forestry employment in Indonesia in relation to the dynamic of forestry sector and its related industries,. The study used systems dynamic to implement the relation between forest structure industries, actors and their institutions. The study found that the current practice of forest management will experience with boom-and-bust of forestry employment, starting with Riau followed by East Kalimantan and Papua. Massive forest plantingwill benefit if it is located in deforested land, but if it is located in land with different existing trees it may jeopardize the employment and community’s livelihoods. Small-scale forestry can boost the employment to meet the overall government target on unemployment and poverty reduction as well as rehabilitation of forest.Keywords: forest degradation, unemployment, land-right scenarios, small-scale forestry, poverty-reduction

Abstract

Tujuan studi untuk mengidentifikasi tutupan vegetasi di area pegunungan menggunakan pemodelan campuran linier (linear mixture modeling). Studi mengkombinasikan data reflektansispektral yang diukur dari fotometer tipe 2703 dengan citra satelit resolusi spasial sangat tinggi yaitu IKONOS. Ada empat tahapan yang dilakukan dalam menganalisis efek topografis (area pegunungan) dalam pengolahan citra dan masalah campuran piksel dalam mengestimasi fitur sayur mayur termasuk teh. Pertama, citra IKONOS dikoreksi dengan cara menormalisasi nilai kecerahan sehingga efek topografisnya dapat direduksi. Tahap kedua mencakup analisis karakteristikreflektansi spektral yang diperoleh dari survei lapangan dan hubungannya dengan citra satelit. Tahap ketiga mendefinisikan jumlah end-member yang digunakan dalam pemodelan campuran (mixture modeling). Akhirnya, fraksi citra teh dinilai dengan hasil klasifikasi metode tak terbimbing(unsupervised). Hasil studi mengindikasi pemodelan campuran dapat digunakan untuk mengidentifikasi teh dalam piksel campuran dengan lebih baik dibandingkan metode klasifikasitradisional.Kata kunci: pemetaan, tutupan vegetasi, area pegunungan, pemodelan campuran linier, citra IKONOS

Abstract

The development of tree-based agroforestry model gives consequences to the space utilization dominated by trees. Farmers take action on this condition by conniving the fallow land. This research was aimed to know the fallow land model, find the key parameters of fallow land model, and formulating the management of fallow land. The spatial model of agroforestry used in this research were trees along border, alley cropping, alternate rows and mixer. The actual data obtained were tree height, tree diameter, crown diameter, land width, and light intensity; the calculated data were land extent, the percentage of crown cover and crown density. The analysis used to determining the percentage of crown cover to calculate the affective arable land area was zone system. Zonation system maked for four zone : 1) zone 1 interval 0-1 m ; 2) zone 2 interval 1-2 m; zone 3 interval 2-3 m; zone 4 interval 3-4m.Key words: agroforestry, fallow land, silviculture, land cover, resource sharing, crown dynamic

Abstract

Most of forestry work has burdened forest workers with heavy workload, which is often exceeding their allowable workload. This workload has been widely measured through energy expenditure-based workload assessment (expressed in kcal/kg/min). However, this calculation method excluded physical characteristic of individual into its calculation, meanwhile it may greatly influenced metabolism system of an individual. Thus, there is a big possibility that the use of kcal/kg/min workload unit in comparing workload among different individuals conducting the same physical work had ended in an erroneous reading.  Therefore, a study on alternative workload measurement that provides a fair assessment when the assessment is conducted among different individuals performing same physical activity is significantly important.  This study proposed an alternative workload calculation approach, in which the workload unit was expressed in %VdotO2max.  The results showed that alternative workload measurement provided excellent accurateness similar to that provided by conventional workload assessment method.  Further analysis showed that  the proposed unit showed a fair reading when the analysis was carried out to more than one individual.  This was because  the proposed unit considered maximum physical work capacity (short term) of each individual in its calculation.

Abstract

Kelestarian pengelolaan hutan merupakan konsep yang samar dan kompleks, oleh karena itu tidak ada satupun alat ukur yang dapat mengukurnya secara jelas. Sertifikasi hutan digunakan sebagai instrumen untuk mengukur kelestarian pengelolaan hutan yang didasarkan atas kelestarianproduksi, ekologi dan sosial. Kriteria dan Indikator (C & I) untuk kelestarian hutan alam produksi dalam sistem sertifikasi di Indonesia (Lembaga Ekolabel Indonesia) menggunakan Analytical Hierarchy Process (AHP) sebagai alat dalam proses pengambilan keputusannya. AHP telah lama dikritisi, antara lain karena pendekatan kompensatori menggunakan modellinier additive utilitas untuk mengintegrasikan -nilai baku. Riset ini bertujuan untuk menganalisa beberapa metoda aggregasi nilai baku sebagai alternatif untuk menilai kelestarian pengelolaan hutan. Fuzzy AHP dan Rule Base (Fuzzy Reasoning Method) dipelajari sebagai metode untuk mengatasi kekurangmampuan AHP dalam menangani secara tepat peubah-peubah linguistik. Data hasil proses penilaian sertifikasi Unit Pengelolaan Hutan Labanan, Kalimantan Timur,Indonesia digunakan untuk menilai kelestarian pengelolaan hutan dengan tiga metode tersebut. Hasil Fuzzy AHP dibanding dengan Normal AHP menunjukkan hasil yeng lebih jelas dan sudah menampung ketidakpastian justifikasi ekspert yang tidak terdapat dalam Normal AHP. Metode Rule Base, yang sangat tergantung kepada pengetahuan dan pengalaman ekspertnya, memberikan hasil yang lebih berarti dan transparan dalam proses penilaian dibanding kedua metode lainnya, yaitu Normal AHP dan Fuzzy AHP.Keywords:  SFM assessment, forest certification, fuzzy decision making, AHP, Fuzzy AHP, Fuzzy Rule Base
