Tree length logging method is an alternative way in timber harvesting to improve the efficiency of timber utilization and preservation of forests resources. This paper studies the performance of tree length logging application method in operational scale. Observation was conducted in the forest area of PT Sarmeinto Parakanca Timber in East Kotawaringin
ABSTRAKMetode sebagai alternatif cara pemanenan kayu merupakan upaya untuk meningkatkan efisiensi pemanfaatan hasil hutan kayu dan kelestarian hutan produksi alam. Saat ini kontribusi produksi kayu bulat hutan alam semakin menurun akibat masih borosnya proses pemanenan dan makin terbatasnya luas hutan alam produksi. Penelitian ini bertujuan untuk mengetahui kinerja penerapan metode pembalakan kayu sepanjang mungkin dalam skala operasional. Penelitian dilaksanakan pada areal hutan yang dikelola dengan teknik silvikultur intensif (SILIN) di PT Sarmiento Parakanca Timber (SARPATIM), Kabupaten Kotawaringin Timur, Provinsi Kalimantan Tengah. Pengumpulan data melalui pengamatan dan pengukuran langsung di lapangan meliputi produktivitas kerja dan biaya penebangan dan penyaradan, limbah pembalakan, faktor eksploitasi (FE) dan kerusakan tegakan tinggal. Hasil penelitian menunjukkan bahwa produktivitas penebangan meningkat menjadi 60,535 m /jam dan produktivitas penyaradan sebesar 31,931 m /jam. Selain itu, penerapan metode dapat memperkecil biaya penebangan menjadi Rp 1.604,36/m dan penyaradan Rp 21.142,75/m , meningkatkan nilai FE mejadi 0,93 dan dapat menekan kerusakan tegakan menjadi sebesar 20,70%.
Tree length logging method is an alternative way in timber harvesting to improve the efficiency of timber utilization and preservation of forests resources. This paper studies the performance of tree length logging application method in operational scale. Observation was conducted in the forest area of PT Sarmeinto Parakanca Timber in East Kotawaringin Regency, Central Kalimantan Province, where Intensive Silvicultural Technique (SILIN) was applied. Data were collected through observation and direct measurements in the field including labor productivity and cost of felling and skidding, logging waste, exploitation factor (FE) and the damage of residual stand. Results show both felling productivities and skidding were improved. The felling capacity was improved into 60.535 m /hour and skidding was improved into 31.931 m /hour. The application of tree length logging can also reduce the felling cost into Rp 1,604.36/m and skidding cost into Rp 21,142.75/m. The method also increase the exploitation factors (FE) into 0.93 and minimize the damage on residual stand by 20.70%.
