Abstract

An investigation on productivity and log­skidding cost using buffalo (Bubalus bubalis) was carried out at the area of lnhutani V in Jambi in 1999. The objective is to get reliable information about such productivity and cost. Connected with this purpose, some related data as collected were i.e. volume of skidded log, skidding distance, skidding­working time, buffalo working time, feeding cost, operator cost, and equipment.Volumes of log which was skidded using buffalo ranged between 0.094 and 0.904 m3/tripwith an avverage of 0.484 m3/trip. Skidding distance using buffalo varied from 10 to 2­12 m with an average of 82 m. The working time varied from 11 to 83 minutes with an average of 30 minutes. The log skidding productivity ranged between 0.035 and 1.211 m3­hm/hour with an average of 0.338 m3­hmlhour. Log skidding costs using buffalo ranged between Rp 681 and Rp23.589 m3­hm with an average of Rp 4.375/m3­hm. It is suggested that volume of skidded log in each round trip and skidding distance be not more than 1 m3 and 250 m, respectively.

Abstract

Pemanfaatan kayu di hutan sampai saat ini masih dirasakan belum optimal, terbukti masih tingginya limbah kayu dari kegiatan permanenan. Limbah yang terjadi dari pohon yang ditebang sampai dengan diameter batang minimum 15 cm adalah sebesar 57%. Oleh karena itu langkah-langkah pengelolaan hutan menuju zero waste perlu dilakukan. Salah satu cara untuk meningkatkan pemanfaatan hutan tanaman adalah memanfaatkan limbah penebangan hutan tanaman menjadi bahan baku serpih.            Penelitian potensi dan biaya pemungutan limbah penebangan kayu mangium (Acacia mangium) telah dilakukan di BKPH Parungpanjang, KPH Bogor pada tahun 2002. Hasil penelitian menunjukkan bahwa rata-rata potensi dan biaya pemungutan limbah penebangan kayu mangiu sebagai bahan balm serpih adalah 0,079 m3/pohon atau 15,4% dan Rp. 15.250/sm. Potensi limbah penebangan mangium sebagai bahan baku serpih yang layak diusahakan adalah sebesar 8,33 sm/ha atau 4,444 m3/ha. Sementara itu harga pokok limbah kayu mangium adalah sebesar Rp. 23.375/sm.Dukungan pemerintah sangat diperlukan dalam bentuk kebijakan yang dapat mendorong kembali masyarakat sekitar hutan untuk memanfaatkan limbah penebangan kayu dari hutan tanaman sebagai bahan baku serpih. Kebijakan tersebut berupa kemudahan dalam memperoleh limbah kayu dengan harga sesuai besarnya biaya eksploitasi dan menetapkan harga dasar serpih yang tidak terlalu tinggi.

Abstract

To accomplish natural forest sustainable. the Indonesian Selective Culling and Planting (ISCP) system is adopted for natural forest management and timber harvesting. Felling trees using controlled system, based on ISCP guidelines. is able to decrease the level of residual stand damage. An investigation on a more efficient treefelling with minimum residual stand damage was carried out at on logging company in Jambi in 2000. The object is to obtain information on working time. productivity offelling and residual stand damage.The investigation results revealed that the level of residual stand damage caused by conventionalfelling system ranged from 12 0-18.3% with an average of 15.3%. and by controlled system varied from 7. 7-12. 9% with an average of 9. 9%. Controlled harvesting system could decrease the residual stand damage of 5.4%. The productivity of conventional felling system ranged from 24.465-44.873 m3/hour with an average of 33.681 m3/hour. Productivity of controlled felling system varied from 16.883-35. 650 m3/hour with an average of 25.012 m3/hour. The productivity of controlled felling system was lower than conventional felling system. For ecological and sustainability reasons, controlled felling system is more promising. PENEBANGAN POHON YANG EFISIEN DENGAN KERUSAKAN TEGAKAN TINGGAL MINIMAL

Abstract

Saat ini, produksi kayu dan keanekaragaman hayati hutan alam di Indonesia semakin menurun. Sejak tahun 2005, Kementerian Kehutanan berupaya meningkatkan produksi kayu melalui sistem silvikultur Tebang Pilih Tanam Indonesia Intensif (TPTII) meliputi pengaturan penebangan, persiapan lahan, dan penanaman. Penelitian ini mempelajari produktivitas, efisiensi, dan pengusahaan hutan di Kalimantan Timur. Hasil penelitian menunjukkan produktivitas teknik penebangan secara konvensional berkisar antara 33,4 – 39,7 m3/jam dengan rata-rata 36,4 m3/jam, lebih tinggi dari teknik penebangan berdampak rendah yang berkisar antara 28,3 – 36,23 m3/jam dengan rata-rata 32,8 m3/jam. Efisiensi penebangan pada teknik penebangan secara konvensional bervariasi antara 84,3 – 88% dengan rata-rata 86,56% lebih rendah dari teknik penebangan berdampak rendah yang bervariasi antara 88,5 – 90,12% dengan rata-rata 89,36%. Biaya penebangan teknik penebangan secara konvensional bervariasi antara Rp 1.712 – Rp 2.023/m3 dengan rata-rata Rp 1.893/m3, lebih rendah dari teknik penebangan berdampak rendah yang berkisar antara Rp 1.884 – Rp 2.412/m3 dengan rata-rata Rp 2.104/m3. Teknik penebangan berdampak rendah pada sistem TPTII membutuhkan biaya tambahan dan menurunkan produktivitas, namun dapat meningkatkan efisiensi penebangan. Di samping itu, penebangan berdampak juga rendah dapat meningkatkan keuntungan sebesar Rp 321,57 juta setahun.

Abstract

The trees have certain optimal ages to be harvested. Beyond those ages, the value of the trees tend to decline. Therefore, good harvesting plans must be created and then followed by refining to expedite forest sustainability. In reality, forest harvesting operation always cause ecological damage. It can not be avoided, but can be minimized. Log skidding as one element of the harvesting operations need to be controlled to decrease residual stand and soil damages.An investigation on residual stand damage, ground exposure, soil displacement and cost on controlled skidding was carried out at one logging company in Jambi in 2001. The objective of the investigation is to find out information about residual stand damage, ground exposure, soil displacement and cost on controlled skidding which could be useful for managing sustainable forest. The investigation results revealed that: (1) the averages of residual stand damage, ground exposure, top soil displacement, productivity, and cost on controlled skidding were 11.3%, 8.6%, 17.720 cm/10m skidding road, 23.886 m3-hm/hour and Rp 12.740/m3-hm, respectively while those averages on conventional skidding were 20.2%, 12.2%, 22.160 cm/10m skidding road, 30.996 m3-hm/hour and Rp 10,080/m3-hm, respectively; (2) controlled skidding can decrease 8.9% of residual stand damage: 3,6% of the degree of ground exposure; 4.44cm/10m road skidding of level of top soil displacement; (3) controlled skidding system increase the cost of Rp 2,660/m3-hm because the productivity of the system is lower than the conventional one. Nevertheless, for ecological and sustainability reasons in the long run, controlled skidding system is more promising and needs to beimplemented.
