“…Table 2 also shows that the felling costs ranged from 0.208 USD/m 3 to 0.238 USD/m 3 with an average of 0.225 USD/ m 3 . Compared to another study conducted in tropical forests at Central Kalimantan, the felling cost is not significantly different, which ranged from 3.001 USD/m 3 to 0.504 USD/m 3 with an average of 0.374 USD/m 3 [20]. However, compared to another study in North Kalimantan, the felling cost was 0.084 USD/m 3 [28], and the felling costs found in this study were considered expensive.…”

Felling of natural forest trees in West Papua Province is carried out mechanically using a chainsaw by applying a selective cutting silviculture system. This study aimed to determine the elements of working time, productivity, and cost of felling as well as factors influencing felling activities using the chainsaw in the tropical natural forests in West Papua, Indonesia. The felled trees are dominated by the meranti wood species group with a minimum diameter of 45 cm. The average volume of the felled tree is about 4.205 m3/tree. The result showed that total felling time ranged from 15.3 to 18.3 min/tree with an average of 16.7 min/tree. The effective felling time was 11.8 min/tree (70.86%) and the delay time was 4.9 min/tree (29.14%). Felling time in making undercuts was on average 1.7 min/tree (9.98%), longer than back cuts time of 1.10 min/tree (6.39%). Total felling time was influenced by various variables: tree diameter, buttress height, and slope. Felling productivity was accounted for between 14.901 m3/h and 17.067 m3/h (15.778 m3/h on average). Felling costs ranged from 3.366 USD/h to 3.473 USD/h with an average of 3.407 USD/h or equivalent to 0.209 USD/m3 to 0.238 USD/m3 with an average of 0.225 USD/m3. To improve the effectiveness of felling time and productivity, this study suggests (1) upgrading the skills of the chainsaw operators through formal or in-house training in felling techniques, and (2) ensuring chainsaw operators bring a tree distribution map completed by field conditions information.

“…Penerapan kebijakan sistem borongan ini sebenarnya secara keseluruhan merugikan PBPH karena menyisakan limbah tebangan dalam volume besar dan mahalnya upah penebangan. Hasil penelitian (Soenarno, 2017) yang dilakukan di Kalimantan Tengah menunjukkan bahwa biaya penebangan dengan sistim swakelola berkisar antara Rp 4.051,11-Rp 6.800,11/m 3 sedangkan sistim upah borongan berkisar antara Rp 6.000-Rp 7.000/m 3 .…”

Saat ini, kegiatan pemanenan kayu di hutan alam lebih efisien dengan diterapkannya teknik pembalakan berdampak rendah (reduced impact logging, RIL). Pemanenan kayu yang lebih efisien akan mengurangi terjadinya limbah yang berakibat meningkatkan angka standar faktor eksploitasi (FE). Ironisnya hingga kini angka standar FE yang ditetapkan oleh Kementerian Lingkungan Hidup dan Kehutanan masih didasarkan pada cara pemanenan kayu konvensional, yaitu sebesar 0,7. Sub region Provinsi Kalimantan Tengah mempunyai peranan besar dalam menyumbang produksi kayu bulat hutan alam baik secara regional Pulau Kalimantan sebesar 61,5% dan secara Nasional sebesar 29,7%, namun belum diketahui banyaknya limbah pemanenan kayu dan besaran standar faktor eksploitasi. Tujuan penelitian ini adalah untuk mengetahui banyaknya limbah pemanenan kayu dan angka standard FE yang dilakukan oleh PBPH di sub region Kalimantan Tengah. Penelitian dilakukan di Perizinan Berusaha Pemanfaatan Hutan (PBPH) yang bersertifikat Pengelolaan Hutan Produksi Lestari (PHPL) mandatory dan PBPH bersertifikat PHPL voluntary. Hasil penelitian menunjukkan bahwa potensi limbah pemanenan kayu akibat pembagian batang di petak tebang rata-rata 0,919 m3/pohon dan besarnya limbah kayu akibat pengujian dan pengukuran di TPn berkisar rata-rata 0,093 m3/pohon. Angka FE berkisar antara 0,80-0,85 dengan rata-rata 0,82. Besar kecilnya angka FE lebih dipengaruhi oleh faktor ketrampilan penebang, kebijakan manajemen PBPH, dan diameter pohon ditebang.

Timber harvesting in natural production forests in Indonesia is still carried out to his day in the form of a bussines license for the utilization of timber forest products-natural forests (IUPHHK-HA). IUPHHK-HA holders have not fully implemented Reduced Impact Logging (RIL). Forest harvesting activities consisting of felling, skidding, bucking, loading, unloading, and transportation of logs are aimed at without significantly disturbing log production and its environment. The purpose of this review is to provide information on RIL in Indonesia. The collection of data was done by using a desk study. Data on productivity, efficiency, costs, damage to the residual stands, and the impact of RIL on emissions were collected. Several research results showed that: (1) logging productivities generally decreased when compared to Conventional Logging (CL), (2) logging efficiency generally increased when compared to CL, (3) logging costs generally increased in the short term, (4) residual stand damages generally reduced when compared to CL, and (5) RIL has potential to reduce emissions compared to CL. It is necessary to do the following: harvest planning such as mapping and distribution of trees, skid trail alignment, design of landings; harvest preparation such as the opening of skid trails, opening of landing places; harvesting such as determining felling direction, felling, skidding, and closure of harvesting such as closure of skid trails and landings.
