Abstract

Penelitian produktivitas dan biaya penyaradan kayu dengan traktor pertanian yang dilengkapi alat bantu dilakukan di hutan tanaman kayu mangium di KPH Bogor. Tujuannya adalah untuk mendapatkan inforrmasi teknis finansial tentang penyaradan kayu dengan traktor pertanian yang dilengkapi alat bantu. Data panjang dan diameter kayu yang disarad, waktu kerja dan biaya penyaradan dikumpulkan.Hasil penelitian penyaradan menggunakan traktor pertanian yang dilengkapi alat bantu sederhana mampu menyarad 3 batang/rit atau 2,075 m3.hm/jam. Traktor pertanian yang dilengkapi alat bantu winch menghasilkan produktivitas penyaradan yang lebih baik, yaitu sebesar 2,328 m3.hm/jam. Biaya penyaradan dengan traktor pertanian yang dilengkapi alat bantu sederhana sedikit lebih rendah dibanding biaya penyaradan dengan traktor pertanian yang dilengkapi alat bantu winch. Disarankan bahwa alat bantu taktor pertanian perlu disempurnakan. Di samping itu penyaradan pada areal dimana penyaradan secara manual tidak mungkin dapat dilakukan, traktor pertanian yang dilengkapi alat bantu dapat dijadikan salah satu alternatif.

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

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.

Abstract

This paper presents the results of an investigation on the use of forest roads as log transportation infrastructure at two logging companies in Jambi  and one logging company in South Kalimantan  carried out in 1990. The objective is to find out the information of the intensity of forest roads use as log transportation infrastructure.  For that purpose, the data on forest road length (km) and actual log production  (m3)  for the period of between three and  ten years were  collected. The results reveal that:1.   Forest roads at several forest companies in Sumatra  and Kalimantan  were commonly unpaved, and therefore, can only be used when they are dry.2.  The average lengths of forest roads built by A, B and C  companies were 6.050 km/year  with the range of between 2.000 and  13.000  km/year;  and  12. 733 km/year  with  the range of between 7.600  and  19.800  km/year;   11.275 km /year with the range of between 2: 565 and 22. 650 km /year, respectively.3.   Actual  log production  ranged from 18,045,48  to 45,555.60  m3 /year  with  the average of 27,249.88 m3 /year for A company; from 19,484.07 to 41,526.29 m3 /year with the average of 31,485.36  m3 /year for B company; and from 15,892.25 to 54,553.95  m3 /year  with the average of 36,745.30  m3 /year for C company.4.   Correction factor to be used in calculating actual production from target production at A, B and C companies were respectively 0. 74 with the range of between 0.36  and 0.98;  0.97  with the range of between  0.96  and 0.99; and 0. 76 with the range of between 0.32  and 1.09.5.  The intensity of forest roads use as log transportation  infrastructure at A, B and C forest companies range between 1,503. 79 and  17,234.05  m3 / km-year  with  the  average of  7,165. 73 m3 / km-year;  between 984.04   and  4,400. 75 m3 / km-year  with the average of 3,076.61  m3 / km-year; and between 1,352.53  and 13,292. 74 m3 / km- year with the average of 5,147.53  m3 / km-year, respectively.

Abstract

Dalam pemanfaatan kayu, pemanenan hutan merupakan tahap kegiatan utama yang dilakukan agar potensi pohon dapat dikeluarkan dari dalam hutan. Banyak atau sedikitnya limbah yang terjadi selama proses pemanenan kayu dapat dijadikan tolok ukur faktor eksploitasi (FE). Selama ini, pemerintah menetapkan angka FE sebesar 0,7. Padahal, paradigma pengelolaan hutan alam sudah semakin baik dengan diterapkannya pembalakan berdampak rendah (reduced impact logging/ RIL) dan/atau berdampak rendah karbon (RIL-C). Dilihat dari aspek ekonomis, nilai FE mempunyai peranan sangat penting karena digunakan sebagai pengali didalam menentukan jatah produksi tahunan (JPT) dan dasar untuk menjadi memperkirakan penerimaan besarnya provisi sumberdaya hutan (PSDH). Sedangkan dari aspek ekologis, penetapan nilai FE yang lebih besar dapat mengurangi terjadinya kerusakan hutan. Hasil penelitian yang dilakukan di 5 IUPHHK-HA di Kalimantan Timur menunjukkan besarnya bilangan FE berkisar antara 0,77 - 0,89. Besar kecilnya bilangan FE lebih dipengaruhi oleh faktor ketrampilan penebang dibandingkan dengan factor kompetensi manajemen IUPHHK-HA.

Abstract

An investigation of the efficiency of tree felling at forest areas using the Indonesian selective cutting and planting system (TPTI) was carried out at 5 logging companies in Central Kalimantan and 3 other companies in South Kalimantan in 1990. The objective is to find the way increasing the efficiency of tree felling at the natural production forests. For that purpose, data on felled tree volume, actually utilized logs and part of good logs left in the forest were collected. The investigationresults are as follows :1. Considering log diameter of 10 cm and up, the efficiency of improved felling technique can be increased by 6. 23 %.2. By using the improved felling technique, the volume of good quality clear bole logs is increased by 4. 90 %.3. The averages of stump heights between improved and existing felling techniques were 51.07 cm and 114.86 cm, respectively.4. the improved felling technique could increase the quality and volume of log for veneer (from 61.34% to 65. 83%) and for sawn timber (from 10.19 % to 10.45 %).5. It is necessary that the existing felling technical guidance and log administration be improved.
