Abstract: | The implementation of planning techniques and timber harvesting is not yet carried out appropriately on timber harvesting in natural forests of Indonesia. Reduced Impact Logging (RIL) is considered as a technique to reform timber harvesting in tropical natural forests. Compared to Conventional Logging, Reduced Impact Logging can reduce the environmental damage caused by timber harvesting. This research purposes are to (1) Identify and quantify the extent of stand damage of trees with diameter 20 cm and up caused by timber harvesting using RIL and CL methods; (2) Analyze the correlation of stand damage of trees with diameter 20 cm and up with slope, stand density and harvesting intensity on timber harvesting using RIL and CL methods; and (3) Compare the amount of the damaged trees with diameter 20 cm and up due to timber harvesting using RIL and CL methods. The research was carried out at IUPHHK PT. Ratah Timber, East Kalimantan from April to July 2011. Plot observations created on square-shaped plots measuring 100 m x 100 m, each 10 plots for both methods. Data collected were number of stand density, intensity of harvesting, and the slope. The results showed (1) Greatest extent of damage that occurred in both CL and RIL harvesting methods was heavily damaged, respectively 66,5% and 74,51%; (2) The factor that influenced residual stand damage on timber harvesting is intensity of harvesting; and (3) RIL method can reduce the residual stand for 9,56% or 2,9 trees per hectar compared to CL method. Teknik perencanaan serta pelaksanaan pemanenan kayu yang baik dan benar belum digunakan dalam pemanenan kayu di hutan alam Indonesia. Reduced Impact Logging (RIL) merupakan teknik yang dipergunakan untuk memperbaiki pemanenan kayu di hutan alam tropis. Dibandingkan menggunakan metode Conventional Logging, metode Reduced Impact Logging dapat mengurangi kerusakan lingkungan yang terjadi akibat pemanenan kayu. Tujuan penelitian, yaitu: (1) Mengidentifikasi dan menghitung tingkat kerusakan pohon berdiameter ≥ 20 cm yang disebabkan pemanenan kayu menggunakan metode RIL dan CL; (2) Menganalisis hubungan tingkat kerusakan pohon berdiameter ≥ 20 cm dengan kelerengan lahan, kerapatan tegakan dan intensitas pemanenan pada pemanenan kayu menggunakan metode RIL dan CL; dan (3) Membandingkan besarnya kerusakan pohon berdiameter ≥ 20 cm akibat pemanenan kayu menggunakan metode RIL dan CL. Penelitian ini dilakukan di IUPHHK PT. Ratah Timber, Kalimantan Timur dari bulan April sampai dengan bulan Juli 2011. Plot pengamatan dibuat berupa petak berbentuk persegi berukuran 100 m x 100 m, masing-masing 10 plot untuk kedua metode pemanenan. Data yang dikumpulkan berupa kerapatan awal tegakan, intensitas pemanenan, dan kemiringan lahan. Hasil penelitian menunjukkan (1) Tingkat kerusakan paling besar yang terjadi baik pada metode pemanenan CL maupun RIL adalah tingkat kerusakan berat, masing-masing sebesar 66,5% dan 74,51%; (2) Faktor yang mempengaruhi terjadinya kerusakan tegakan tinggal pada pemanenan kayu adalah intensitas pemanenan; dan (3) Metode RIL dapat menurunkan kerusakan tegakan tinggal sebesar 9,56% atau sebanyak 2,9 pohon per hektar dibandingkan dengan metode CL. |
