Abstract

Kajian ini dilakukan untuk mengevaluasi target volume tebangan kayu ramin tahun 2003 di PT. DRT (Diamon Raya Timber). Evaluasi dilakukan menggunakan metode French (1883). Hasilnya memperlihatkan volume tebangan untuk seluas 2.000 ha sekitar 9.104,3 m3 berasal dari sebanyak 3.672 pohon. Dari hasil penelusuran pada lokasi bekas tebangan diketahui penebangan di1akukan antara 5,75-14,61 pohon/ha atau rata-rata 10,18 batang/ha; dengan sekitar 1,3-4,0 batang diantaranya dari jenis kayu ramin. Sumber informasi lain memperlihatkan pohoo ramin yang ditebang antara 5,65 - 7,22 batang/ha atau rata-rata 6 batang/ha. Besaran ini memperlihatkan bahwa perusahaan telah berusaha menerapkan prinsip kelestarian pemanenan di hutan a1am. Kendati demikian untuk menambah tingkat kelestariannya maka penebangan pohon berdiameter besar perlu dibatasi, utamanya diperlukan untuk penyediaan pohon induk yang sangat penting sebagai sumber benih dao anakan alam masa mendatang.

Abstract

Hingga saat ini limbah tebangan hasil dari tebang penjarangan maupun tebangan habis jenis kayu tusam, utamanya pada bagian bawah batang yang disadap getahnya yang disebut brongkol, masih tetap melimpah.   Rendahnya pemanfaatan terjadi karena berbagai sebab, antara lain harga jual tidak seimbang dengan biaya  pemungutannya. Untuk meningkatkan nilai tambah telah diuji coba pengoperasian meja penggergajian yang digerakkan dengan mesin Expo-2000. Dengan alat ini, limbah tersebut dapat dibuat menjadi berbagai produk seperti kaso, papan,  reng, dan bahkan balok, tergantung ukuran  bahan Selama  kegiatan uji coba diketahui  bahwa  diameter  limbah  bervariasi  dari  8 - 38cm, dengan panjang 0,66 - 1,5 m. Rata-rata penggergajian dolok memerlukan waktu 188,7 detik atau sekitar  3 menit untuk sortimen clolok berukuran 1,3 meter clengan diameter 20-30 cm menjadi papan tebal 3 cm. Dengan penggunaan gergaji mesin tersebut hampir 55% lebih dari brongkol yang semula d.ikategorikan sebagai Limbah dapat d.itingkatkan nilainya menjad.i berbagai procluk siap pakai. Hasil analisis biaya memperlihatkan bahwa biaya pemilikan clan biaya  operasi  seluruhnya berjumlah  Rp 35.720/jam, tercliri dari biaya tetap Rp 4.770/jam clan biaya tak tetap Rp 30.590/jam. Dengan kemampuan  mengolah limbah  1,75 m3 /jam, berarti biaya pemilikan clan penggergajian potongan kayu aclalah sebesar Rp 20.411/ m3•  Sela.in itu biaya pengeluaran clan pengolahan kayu aclalah sebesar Rp 36.200/ m3 (d.ibulatkan)-. Apabila tarif procluksi pengeluaran clan pengolahan kayu sebesar Rp 40.000/m  maka nilai NPV clan IRR secara berurutan adalah sebesar Rp 3.887.479  clan 19,59%

Abstract

To enhance effectiveness of natural resources evaluation an assessment on the trend of land- use and its impacts is necessary. This is needed by regions which are interacted each others and covering large areas. A remote sensing technology is a reliable and appropriate choice for such area. A study on the land-use assessment was employed using manual method through the implementation of Spot, Landsats, and Radar imageries. The results were as follows:1) Until the year 1980, the concession area situated at Long Nah, administratively under authority of PT Inhutani I. East Kalimantan were mostly still covered by virgin forest with occasional and scattered small villages2)  Manual interpretation using imageries of Spot, Landsats and Radars disclosed the following results: (a) Spot imageries turned out to be 64. 7% as the correct figure and 35.3% as the false figure;, (b) Landsat imageries interpreted 53.3% as correct and 46.7% as false; (c) Radar imageris conducted in March and April 1998 revealed 38. 1% as correct and 61.9% as false.3) Changes forest land-use during the period 1980-1998 occurred in low-land dry forest andpartly in swampy forest, which were further converted to the plantation forest. Meanwhile, the changes for other land-uses among others agriculture were almost insignificant ( less than 3%). This is because soil layers in the corresponding land were thin and acidic rendering unsuitable for agriculture activities.4)  In order to reduce high commission error, the appropriate number of strata relevant to the land-use interpretation should not be too detailed but adequately established as simply aspossible.

Abstract

Biomass of timber post forest harvest (natural forest or made man forest0 that available at the felling site is one of natural sources which have a volume still potentially. These materials can be use for energy sources or fulfil of additional materials for pulp and paper industries or another product as availability of volume, type and seize of biomass which usually called as wastes. This potency can be obtained from plantation forest and or natural forest especially on conversion forest production in the form of wastes of bucking, trimming, main stem, branch and stump. The problem is how to collect it in an effective and efficient way. The availability of wood wastes among other due to other function has high condition, particularly for plywood and timber construction as well. For example the length of wood to short, to small of diameter, many defect, decay and holes or bending. Other form are stump and roots, branches and to many bandings. Mostly all of wood wastes are used for layer when equipment wills passing that rows. Similar thing can also obtain from limb trees hit by tree which is cut, hit on skidding operation and road construction.

Abstract

Current management of natural forests or crops are facing a lot of problems. Among the big issues are issues of law and policy sentralistis, which is less supportive, practice the utilization that are not concerned with sustainability and the environment, a proliferation of Wild wood processing industry, logging, looting the land, forest fires, floods and landslides, drought, destruction of the wealth and diversity (biodiversity), as well as many other social problems again. It all became a part of the integral to be a consideration in an attempt to rebuild the forest and forestry. In this reform era, Manager of natural resources forest (SDH) should change the paradigm, which is based with the appropriate forest, environmental understanding is a comprehensive, long-term and eco-efficient. In an effort to achieve the goal in question, it is very necessary that harvesting methods and strategies of eco-efficient and appropriate, so that the results can be obtained in addition to wood, can be built to the maximum return of damaged forests, also exploiting the existing potential can still be managed effectively and efficiently, among others achieved by implementing eco-efficient (productive and minimum impacts ").

Abstract

Since industrial area around Bekasi-Karawang-Purwakarta enhanced, it is necessary considering the review of alternate optimally function of the forest production as conservation area. It is important due to existence of District autonomy which can arrange the plan and manages natural resources and not only for environment, but also from economic and social aspects. The reasons are (1) benefit in enjoying transportation view; clean air along journey with green plantations, (2) indirectly as media education and counselling for how important of existence forest, (3) production of wood yield cannot real supplier that could answer demand wood requirement, (4) wood product unfavourable quality, (5) of [his/its] function for environmental health as absorber of dirty air as effect of air pollution from industrial and the reduce noise, ( 6) function of natural beauty with variation of other life’s and birds. Others benefit among others are (1) laboratory of various target of biological research and conservation, ( 2) medium of development for recreation service , ( 3) sample for environmental greening movement in more proactive and ( 4) civilizing movement for all birds flown freely.

Abstract

Timber extraction from felling area to road side is not an easy job. This activity facing a number of difficulties particularly due to geo-biophysical conditions, such as steep terrain, up and/or down-hill, valley or river-to be crossed, slippery road and also the size of the timber and low accessibility. To anticipate those obstacles two engineering designs of the skyline system had been tried, the so called Expo-2000 Generation-1, using gasoline engine of 6 HP (G-1), and Expo-2000 Generation-3 using dieselengine of 12 HP (G-3). G-1 model has been tested in Cimeong and Rancaparang in 2011. G-3 model has been examined in Cibatu Canjur and Cibaliung Banten in 2013. This paper evaluates the modification of skyline system for steep terrain and to compare the performance between two modified skyline systems, in term of productivity and cost. The data collected included working time, log volume extracted, log extraction distance and fuel used. Data were analyzed to get the average productivity and cost of operation. Result show that prototype G-3 with logs in horizontal position at a distance of 130-430 m, can extract logs averaging 1.72 m3/hr, at a cost of about Rp 80,346/m3, while prototype G-1 and logs in vertical position at a distance of about 50-320 m, could only extract logs averaging ± 0.85 m3/ hr at a cost of about Rp 156,351/m3. It suggests that prototype Expo-2000 G-3 is more effective for log extraction logs in steep terrain.
