Abstrak: ASEP ROHANDI. Strategic Development of Forest Tree Seed Sources Based on Spatial and Land Potential in West Java. Under the direction of BUDI MULYANTO and UUP S WIRADISATRA. Deforestation affects forests function such as conservation and production. Recovering the functions can be conducted by any means including land rehabilitation and conservation, and increasing the forest yield production through the extensive planting programme on critical land degradation and increasing the land productivity. Based on the research results indicated the potential area for planting target covers 1 235 210.50 hectares. The implication of this fact that the need of seed/seedling will be in huge number. The seed/seedling procurement in good quality (physical, physiologycal and genetical) in sufficient number in continous way is still a facing problem today. In relation to that condition, the need of strategic seed procurement has to be planned in many steps to guarantee seed availability and to support the sustainability of forest plantations. Another result of this research indicated that the forest tree seed sources distribution in West Java is mostly spreaded in the land that managed by Perum Perhutani (99.14%), and the rest of them managed by other institutions including government institutions (0.66%), universities (0.17%) and public society (0.04%). The seed sources mostly classified into seed stand (seed stand identification and selection) that need improvement of the class/quality of the seed sorces and intensive silviculture treatments for increasing the seed production. The total of seed production dominated by jati (50.19%) and mahoni (30.18%), as the main species in planting programme. The area of potential land for the development of priority species, such as for jati covered 371 217.60 hectares, mahoni 303 741.85 hectares, pinus 329 177.23 hectares, sengon 39 647.06 hectares, rasamala 100 969.18 hectares, and damar 90 457.59 hectares, that can be used for prediction of seed procurement and the seed sources area as a guidance in the seed sources establishment programme. That areas were determined by criterias as follow : nearest distance from the seed sources location, ecanomic value of timber and physical constrain to the growth of tree. The need of seed procurement for planting is 2 182 575.89 kilograms that could be such huge number and could not be procured entirely from the exist seed sources as a matter fact it is still need seed procurement in immediate planning through the selection of forest stand into the seed sources, the use of trees seed or seed imported from other countries. The seed procurement in the long term can be achieved by the seed sources establishment combined with the tree improvement programme and forest resources genetic conservation. Based on the potential seed production of the exist seed sources, the seed procument for the forest plantations for jati will need 22.14 years, mahoni 54.79 years, pinus 138.60 years, rasamala 0.98 years and damar 40.19 years, in the mean time for sengon that would need the seed sources establishment before. If the entire area as a target for planting, West Java will has forest area 1 235 210.50 hectares or equal to 28.61% of the total area of

Judul: Strategi pengembangan sumber benih mindi (Melia azedarach L.) pada hutan rakyat di Provinsi Jawa Barat
Abstrak: Melia azedarach L. or mindi (local name) is one of the widely planted exotic species in Indonesia, mostly found in community forests in West Java. It is still an urgent need for improvement of mindi plantation productivity, especially in community forest in West Java. One of the factors that affect forest productivity is high quality seed, but seed quality is not easily obtained by farmers. For this it is necessary to carry out a strategies which can support the development of seed sources in the community forest. The general objective of this research is to formulate development strategies of mindi seed sources in the community forest in West Java, while specific purposes of this study are to (1) determine the genetic and morphology diversity of mindi in the community forest in West Java, (2) improve seed pre-treatment to develop the seed viability of mindi, and (3) analyze of socio-economic and institutional aspect of farmers, to support the development of the seed sources. Six populations of mindi plantation in the community forests were chosen for this research. i.e Nagrak village (Bogor); Megamendung (Bogor); Hamlet of Gambung (Bandung); Wanayasa subdistrict (Purwakarta); Padasari village (Sumedang) and Babakan Rema village (Kuningan). RAPD markers were used to assess the genetic variation, while various pre-treatments employing chemical and physical methods were tested to improve seed viability and vigor. SWOT analysis was used to evaluate the capacity of farmers in developing seed source. The results showed that the genetic variation of mindi in community forests in West Java was moderate ranging from He = 0.1603-0.1956. With respect to seed treatment, the use of sulfuric acid (95%) increased the viability of seed by 57% over control, especially seed from Padasari (Sumedang) population. Prospective populations to be developed for seed sources were proposed namely Padasari (Sumedang) and Legok Huni (Purwakarta). Evaluation of socio-economic and institutional aspect in these two location showed that generally farmers have the sufficient capacity to manage community forests. Four strategies that can be used to develop seed sources of mindi in community forest in West Java : i.e 1. The strategy based on utilization of plant genetic resources of mindi to increase seed production in order to meet the need of mindi timber market. 2. The strategy based on market and networking opportunities to improve the quality of mindi seeds . 3. The strategy based on capacity building and institutional development of farmers in the cultivation of mindi. 4. The strategy based on increasing farmers' interest in cultivation of mindi In conclusion, effective strategy of mindi seed source development should emphasize following important considerations such as the utilization of exisiting genetic resources, enhancement of institutions and networks as well as optimizing opportunities in mindi timber markets.
