Kegiatan pemanenan kayu memberikan kontribusi yang sangat besar terhadap produksi kayu. Pohon produksi yang berada di dalam hutan tidak dapat dimanfaatkan jika tidak ditebang dan tidak dikeluarkan dari dalam hutan. Metode penelitian ini adalah membuat 6 plot contoh pengamatan (PCP) masing-masing 3 PCP untuk teknik perbaikan (TP) dan 3 PCP untuk teknik konvensional (TK) pada satu petak tebang, melakukan penebangan pohon dan penyaradan dengan  TP dan TK, melakukan pengamatan  dan pengukuran produktivitas pemanenan kayu dan luas areal hutan yang terbuka akibat penebangan dan penyaradan serta menganalisis pengaruh kedua teknik terhadap produktivitas  areal hutan terbuka dengan uji t. Tujuan penelitian adalah untuk mengetahui pengaruh dua teknik pemanenan kayu terhadap produktivitas dan areal hutan terbuka. Hasil penelitian menunjukkan bahwa : 1) Rata-rata produktivitas penebangan dengan TK dan TP masing-masing adalah 10,60 m3/jam dan 13,95 m3/jam 2) Rata-rata produktivitas penyaradan dengan TK dan TP masing-masing adalah 7,25 m3/jam dan 9,60 m3/jam;  3) Rata-rata areal hutan terbuka akibat penebangan dengan TK dan TP masing-masing adalah 15,67% dan 7,43% ; 4) Rata-rata areal hutan terbuka akibat penyaradan dengan  TK dan TP masing-masing adalah 10,50% dan 6,68%. Menerapkan teknik perbaikan dapat mengurangi terjadinya keterbukaan hutan pada penebangan dan penyaradan masing-masing sebesar 8,24% dan 3,82%.ABSTRACTTimber harvesting provides a very large contribution to timber production. Tree production that is in the forest can't be used if they are not felling and removed from the forest. This research method is to make 6 sample observation plot (SOP) each 3 SOP for improving technique (IT) and 3 SOP for conventional technique (CT) on one logging compartment, do felling and skidding by IT and CT, make observations, and measuring the productivity of timber harvesting and the area of open forest due to felling and skidding and analyzing the effect of the two techniques on the productivity of the open forest area with t-test. The research objective was to determine the effect of two timber harvesting techniques on productivity and open forest areas. The results showed that the average productivity of felling by CT and IT was 10.60 m3/hour and 13.95 m3/hour respectively. The average productivity of skidding by CT and IT was 7.25 m3/hour and 9.60 m3/hour respectively. The average open forest area due to felling by CT and IT was 15.6% and 7.43% respectively.

Forestry Plantations

Forest resources can be utilized through various activities in the land-based sector, including forestry, plantations, and mining. The implications of the issuance of various permits are indicated to cause changes in the area of forest and land cover. This paper aims to analyze and explain the implications of the various land-based sector licenses that have been issued by the local government and the central government on the condition of forest areas in Riau Province. The research method was carried out with qualitative descriptive analysis, through interviews, spatial analysis, and review and tracking documents. The results of the study showed that during the period 1986-2017 there had been a change in the area of forest area and land cover. The biggest changes in forest areas occur due to the conversion of forest areas into plantations, while the largest land cover changes in successive classes are land cover for plantations (Pk), forest plantations (Ht) and mining (Pn). Some of the recommendations that we propose are the temporary dismissal of licenses in the Riau forest area, the rearrangement of all licenses related to forest areas, increasing integrity and willingness of all parties in Riau and the central government in sustainable forest management.

Local Ordinances

Abstract Local governments may enact ordinances that have a substantial impact on forestry operations. Direct estimation of the economic impact of ordinances requires site-specific forest inventory data and management assumptions. In this study, we attempt to quantify, for four counties in Virginia,the forest area that would be subjected to timber harvesting restrictions under local ordinances. Ordinances that restrict timber harvesting within buffer zones of roads, streams, and property boundaries were simulated for four study counties. Using GIS overlay analysis with forest cover data,estimates of forest area within these buffers were obtained. In addition to this direct effect, we considered indirect effects of ordinances as they fragment potential forest management parcels to small sizes (<20 ac) deemed less conducive to operational forest management. Direct effectsranged from 9 to 33% of operable forest area and averaged 21% of operable forest area. Indirect effects averaged 7% of operable forest area, or ⅓ of the direct effect. Ordinances focused on protecting visual quality affected twice as much forest area as ordinancesdirected toward preserving water quality. Of the total forest area in these four counties, 13.6% lies in protected areas, 27.7% is in inoperable small parcels (prior to ordinances), and 16.7% is affected directly or indirectly by ordinances, leaving only 42% offorest area potentially available for management.

Support Decision Making

Several multi-criteria decision support methods have been introduced to sustainable management of natural resources, but different methods suit different planning situations. One way to support decision-making is to apply voting theory. In this study, a multi-criteria decision-support method based on voting theory, called multicriteria approval (MA), is applied to wood supply chain management in a forest area owned by the state of Finland. The area is called Leikko and is located in the rural municipality of Pieksämäki. MA seems to have some promising features in relation to participatory decision support. The most essential advantages are its ease and comprehensibility. MA is also able to deal with ordinal and imprecise information. Since the method does not demand much preference information from interest groups, the inquiries may be conducted using the Internet. In the case study, nine timber-harvesting alternatives were devised for the forest area. The study involved seven interest groups, whose representatives defined seven criteria by which the alternatives were compared. The purpose was to find a consensus or compromise solution for a practical harvesting schedule. Two different versions of MA were tested and compared from the participatory decision-support aspect. Usability and ease of method, the comprehensibility of the inquiries, and the congruence of the results were examined.

Prescribed fire is used as a site treatment after timber harvesting. These fires result in spatial patterns with some portions consuming all of the forest floor material (duff) and others consuming little. Prior to the burn, spatial sampling of duff thickness and duff water content can be used to generate geostatistical spatial simulations of these characteristics. Results from field studies indicated that spatial patterns of duff characteristics occurred, and they were then modeled by kriging, simulation and a trend-surface modeling techniques. The higher elevations of the study unit burned more severely than the lower portion. This is believed to be due to the heat generated by the fire drying out the upper portions of the units, thus consuming more duff material and thinner pre-burn duff thickness due to ground-based harvesting techniques. Attempts to predict duff consumption and subsequent post-burn duff thickness were successful using a trend-surface model developed for this site and a general duff consumption model. Knowledge of spatial patterns of duff remaining may help land managers adjust prescriptions and alter ignition patterns to reduce areas where total consumption of duff might occur.

The existence of large plantations in Indonesia has proven the failure of individualism value to uphold agrarian justice. This study aims to examine regulations regarding to the land ownership which contradicts with social function principles of Land Cultivation Rights (LCR) and provide recommendation for setting the land ownership which can realize land utilization for plantation ideally. This study employs normative legal research method by statute and conceptual approach. The legal materials were analyzed by inductive, deductive and interpretative syllogism. The results of this research are as follows. First, regulations on Site Permit, Plantation Operation Permit and Release of Forest Area for Plantation based on utilitarian justice and concentrative land ownership are not in accordance with social function principles of Land Cultivation Rights (LCR). Second, the setting of maximum ownership for plantation companies should be based on their type of plants and given fully assets that enable the plantation companies to use the land optimally.Keywords: Land Cultivation Rights, cultivation land area, people’s welfare
