Judul: Kuantifikasi Kayu Sisa Penebangan Habis Jati di RPH Panggung BKPH Dagangan KPH Madiun Perum Perhutani Unit II Jawa Timur
Abstrak: Along with increasing population and the needs of any wood, both for the needs of buildings manufacture, furniture, or exported also increase. This requires the utilization of wood more efficiently and effectively, due to declining of forest production in Indonesia, which subsequently resulted in less availability of raw materials, including the teak. Recently research on the teak is focused on the improvement of tissue culture technique, genetic improvement, improvement of tree quality, and thinning. Meanwhile, research on utilization rate of the wood waste of clear cutting of teak is rarely done. The research was conducted at 70C sub-compartment in RPH Panggung BKPH Dagangan KPH Madiun. The number of tree samples is 48 trees. Tree sample was felled during logging operation in the field. All of clear cutting 48 trees sample result was quantified, both commercial and non-commercial logs. The total volume of 48 trees sample felled was 116,43 m³ with average volume per tree is 2,43 m³. The round wood comes mostly from the main stem (67,85%), upper stem (16,44%), branches and twigs (2,10%), a short cut (4,67% ), small assortment (5,94%), and stump (3,00%). Total volume of commercial was 100,59 m³ with an average volume of 2,09 m³ per tree. Commercial woods were from the main stem 67,85%, upper stem of 16,44%, and branches of 2,10%. On average, each tree produced 11 logs KBK, 6 logs KBS, and 7 logs KBB. The total volume of waste wood from 48 trees sample was 15,84 m³, or an average per tree was 0,33 m3. Based on its origin, waste wood volumes of stump is 3,49 m³ (22,05%), the volume of short cut from the main stem is 0,47 m3 (2,42%), upper stem at 0,49 m³ (2,57%), branches of 4.48 m³ (23.28%), and small assortment of 6,91 m³ (35,96%). Wood recovery factor of clear cutting age class VII is 86,39% and the residue factor is 13,61%.

Judul: Harvesting Waste of Pine Wood and Exploitation Factors in KPH Kedu Selatan Perum Perhutani Regional Division of Central Java
Abstrak: Pemanfaatan kayu di Indonesia sampai saat ini belum efisien sehingga hanya sebagian pohon yang digunakan. Hal tersebut disebabkan oleh jumlah kayu yang dikeluarkan dari hutan umumnya masih banyak yang termasuk berupa residu atau limbah pemanenan. Penelitian ini dilaksanakan di KPH Kedu Selatan dengan jenis tanaman yang ditebang adalah pinus. Penelitian ini bertujuan untuk menganalisis volume limbah kayu penebangan dan angka faktor eksploitasi dalam kegiatan pemanenan kayu. Penelitian dilakukan dengan menggunakan Metode Pohon Penuh (Whole Tree Method). Limbah dalam penelitian ini berupa tunggak, batang bebas cabang, batang atas, dan cabang dan ranting dengan diameter maksimal 5 cm. Hasil penelitian menunjukkan limbah pemanenan dari 67 pohon contoh yang ditebang dengan bekas sadapan pinus dimanfaatkan yaitu seluruhnya terjadi di petak tebang terdiri atas limbah tunggak 69%, batang bebas cabang 4%, batang atas 23% serta cabang dan ranting 4%. Limbah pemanenan kayu tanpa memanfaatkan bekas sadapan pinus terdiri atas limbah tunggak 14%, batang bebas cabang 81%, batang atas 4%, dahan 1%. Angka faktor eksploitasi berdasarkan pendekatan persen limbah dan pendekatan It, Is, Ia dengan bekas sadapan pinus dimanfaatkan sebesar 0,94. Faktor eksploitasi dengan bekas sadapan getah pinus tidak dimanfaatkan, berdasarkan pendekatan persen limbah dan pendekatan It, Is, Ia sebesar 0,67 dan 0,68. Kata kunci: faktor eksploitasi, KPH Kedu Selatan, limbah pemanenan kayu, pinus, The utilization of wood in Indonesia has not been effective so only some trees are used. This is because most of woods taken out from the forest are in the form of harvesting waste. This study was conducted at KPH South Kedu focusing on pine trees that have been cut down. This study aims to analyse the volume of logging residue and the number of exploitation factors in wood harvesting activities. A research was carried out using the Whole Tree Method. The logging residue was defined on stumps, main stems, upper stems and branches and twigs with diameter minimum 5 cm. The results of the study showed that harvesting waste from the 67 sample trees from the cutting plots with pine leads was used consisting of 69% stump waste, 4% branch-free stems, 23% scion, and 4% branches and twigs. Wood harvesting waste without utilizing pine leads consisting of of 14% stump waste, 81% main stems, 4% upper stems, and 1% branches and twigs. The exploitation factor figures based on the percent waste approach and the It, Is, Ia with pine leads was used approaches are 0,94 respectively. The exploitation factor figures based on the percent waste approach and the It, Is, Ia without utilizing pine leads approaches are 0,67 and 0,68.
