Abstract

This article is a conceptual review on Rova et. al. (2001) “When Regulation Fails: Vendace Fishery in the Gulf of Bothnia”. A relevant core message and its implication was drawn considered as a useful lesson learnt, especially for our future option on direction of natural resources management (NRM) reform, including that on forestry. There is a strong relationship between characteristic of natural resources, social conditions of its stakeholders and the institutional structure of its management. The institutional arrangement need to seriously taking into account this essential relationship; including efforts to guarantee that all resiliencies (institutional, managerial, social and ecological) are materialized. These resiliencies could be existed and mutually powerful if and only if the authority of the NRM was not centralized and was based on the NR characteristics by themselves. Need a serious institutional arrangement that is not just for having a restructured institution, but also have to materialize all the resiliencies and provide the consequences of having options for collective actions toward joint outcomes: the sustainability of the NRM. This is a core message actually implying to where the future NRM reform to be directed, especially from institution point of view.

Abstract

Tanjung (Mimusops elengi) is a multipurpose tree species, besides the use of its wood for bridge, boat, floor, door, and furnitures, other parts of this tree such as root, leaves and bark, can be used for medicine. This species is one of tree species that potential be developed in planting programme. Tanjung seed has variation in weight and size that need information in how the variation will influence the germination and the seedling growth. The seed has been collected in Padang, West Sumatera. Research was done to examine the influence of seed size to the germination and physical quality of seedling by using the extracted seed. The seeds were divided into three parts in size including large, medium and small. The experiment design was completely ramdomized design. Every unit of the experiment consist of 3 replications that contain 100 seeds each replication for germination and 25 seedlings each replication for the growth of seedling. Sterilized medium for germination and the growth of seedling was mixed of soil and sand (v/v 1:1). The parameters to be observed were germination percentage and speed of germination, and height and diameter of seedling. The results indicated that for collection of tanjung (M. elengi) seeds should be done only at the large and medium size caused by the capability of the seed to grow to be seedling within 3 months in the nursery higher compared to the small size.

Abstract

This study was conducted to acquire how forest policy making process and implementation have been going on. The role of discourses, knowledge, actors and their networks determine effectiveness of policy debate to meet its goal. Forest policy making process and implementation was not occurred in a linear process as constructed in the rational framework. Imperfected knowledge creates dispute resolution. Effective interaction among actors to solve their diverse perception was determined by knowledge as well as discourses. The strength of actors and their networks and gap of their interest are significant factors to meet their agreed solution. The facts of forest policy process and implementation are expected to be understood by stakeholders and they should bear in mind that effort to improve performance of forestry development based on implementation of existing policy and policy reform remain unpredictable. This analysis are also expected to be used by stakeholders to get better policy intervention strategy.

Abstract

The purpose of land use planning on a river basin or a watershed is "to promote the accomplishment of service wide objectives and targets" subject to the lands potential and the public's desires. This paper aimed to describe a representative formulation of the analitical hierarchi process and linear programming application and show how it may be modified for goal programming. The purposive sampling was used to collect primary data. From five persons were represented each stakeholders on a watershed. The secondary data was collected from the report of each stakeholders and internet. The results show that goal programing had generated considerable interest as a tool for land use planning in multiple goal situations. It does present problems in terms of somewhat difficult data requirements-linearity in its usual form, possible inferior solutions, and lack of explicit recognition of tradeoffs.

Abstract

Provenance trials is one of planting test activities aimed at finding the best provenance in a certain area of forest plantations. The best provenances can be used for establishing the seed sources in the location. The objective of this research was to identify the character or trait performed in every provenance of A. mangium to the observed variable and to see the relation between variables in order to find the potential provenances that can be developed as seed sources. Provenance trials stand as an object for this research was planted in 1995 in Parung Panjang Forest Research Area with Completely Random Block Design. The spacing in planting between trees was 3 metres located at 3 blocks. Number of provenances to be observed were 15 provenance. In every provenance was taken 5 trees sample randomly that equal to 75 trees in each block as representave of every provenance. Totally the sample trees was 225 trees from the 3 blocks. The variables to be observed in this research were tree height (X1), clear bole (X2), tree diameter (X3), tree volume (X4), stem form (X5), branching system (X6), dan bentuk tajuk (X7). Analisis yang digunakan dalam penelitian ini adalah analisis biplot dan korespondensi.

Abstract

Objective of this study was to provide spatial information of Javan gibbon habitat suitability and distribution in Gunung (Mt.) Salak area for Management Authority of Mt. Halimun-Salak National Park. Informations on Javan gibbon distribution was collected through a number of survey during December 2005–June 2006 in Kawah Ratu (Parakan Salak, Sukabumi), Pondok Wisata Cangkuang (Cidahu, Sukabumi), and Bobojong Village (Bogor). Twenty two groups were identified using direct count and triangle count method from over 47 identified positions. Habitat suitability was formulated based on10 ecogeographical variables (criteria), consisting of forest type (primary forest, secondary forest, low-land forest, and submontane forest), slope (0–15%, 15–45%, >45%), and distance to non-forested land, river/water body, and road/tracks. The result showed that Mt. Salak consisted of 13.20% (17.53 km2), 26.25% (34.86 km2), 19.40% (25.77 km2), 4.16% (5.53 km2), and 20.17% (26.78 km2) of high-suitable, suitable, moderate suitable, less and low suitable level subsequently, and 12.69 km2 or 9.56% was not suitable for Javan gibbon habitat. It was also revealed that that 3 and 9 groups were living in high suitable and suitable habitat respectively; 13 groups in moderate suitable, while for each less and low suitable habitat, 2 Javan gibbon groups lived in.
