Abstrak: The role of forestry sector in national economies show a declining trend. This decrease was caused by various factors. One of them is the occurrence of an imbalance between supply and demand for logs in which there is excess demand for primary wood processing industry. Many efforts have been made such as the arrangement of primary wood processing industry and implementation of a log export ban, but has not given encouraging results yet. This research is applying a simultaneous equations model of the Indonesian timber market system that are more detailed than previous studies. On the supply side, the behavioral model of timber supply from various sources (natural forests, plantation forests and community forests) is constructed. Meanwhile, on the demand side, this research constructed demand behavior of sawntimber, plywood, and pulp industries. The model developed is intended to answer questions relating to (1) the factors that influence production of roundwood production and its derivatives, (2) forms of government policies that ensure the sustainability of the forest industry (upstream-downstream), and (3) policies that can reduce the gap of supply and demand of logs. 2SLS method was used for model parameter estimation. The results show that the decision to determine the extent of timber harvesting area in natural forest and plantation forest are influenced by previous cutting experience in addition to the demand by the industrial roundwood, roundwood prices, taxes and levies and wage rates. Roundwood production from natural and plantation forests are influenced by land productivity, while for community forest production is more affected by extensive logging. Level of demand by the industry is affected by the production of primary wood processing industry, the world price of processed wood products, and the price of logs. Efforts to accelerate the decline in the gap can be done through increased productivity of natural forests through the implementation of intensive silviculture. Other efforts that could be implemented are acceleration of development of community’s plantation forests (HTR) in production forests are not burdened with rights, implementation of compensation fee for the people who developing HTR as much as their opportunity cost if they reduce cash crops in HTR area simplify the procedure so that the community can meet the required conditions, granting access to financing credit, encouraging participants to plant perennials HTR; application of multi-system silviculture. Increased production of logs per unit area as described above is expected to increase the contribution of the forestry sector, through increased taxes and charges up to certain limits. Application of the use of efficient wood processing technology, especially in the application of new industrial units, to offset rising production costs, for example increase the wage rate.

Judul: Econometric Analysis of the Development oflndonesian Plywood Industry 1975-2010: A Policy Simulation
Abstrak: Dengan menggunakan model persamaan simultan yang mengaitkan industri kayu lapis dan industri log, permintaan kayu lapis pasar domestik dan ekspor, serta permintaan dan penawaran kayu lapis dunia, studi ini bertujuan untuk menganalisis faktor-faktor yang mempengaruhi perkembangan industri kayu lapis Indonesia dan prospek perkembangan industri kayu lapis ini di masa mendatang, khususnya dalam periode 2000-2010. Hasil dugaan menunjukkan bahwa perilaku produksi log dipengaruhi oleh nilai tukar rupiah tcrhadap US $, melemahnya nilai tukar rupiah terhadap US $ akan diikuti oleh meningkatnya produksi log. Produksi kayu lapis Indonesia tergantung pada besarnya jumlah log dan tingkat teknologi pengolahan kayu lapis yang digunakan. Hasil simulasi menunjukkan bahwa krisis ekonomi yang melanda Indonesia sejak pertengahan tahun 1997 mengakibatkan melemahnya nilai tukar rupiah terhadap US $ secara drastis yang diikuti dengan dicabutnya larangan ekspor log pada tahun 1998 sesuai dengan komitmen dengan IMF, diberlakukannya penerapan ekolabelling, penurunan tarif impor secara bertahap oleh negara pengimpor, dan perbaikan teknologi pengolahan yang meningkatkan produktivitas industri kayu lapis akan menyebabkan terjadinya peningkatan produksi log Indonesia yang cukup tinggi di masa mendatang. Karena permintaan log oleh industri kayu lapis relatif tidak mengalami perubahan, ini berarti bahwa sebagian besar dari peningkatan produksi log tersebut ditujukan untuk pasar ekspor karena harga log di pasar internasional jauh lebih tinggi daripada di pasar domestik. Kemungkinan ini perlu diwaspadai karena berpotensi mengancam kelestarian hutan produksi nasional, dan tentu saja, prospek perkembangan industri kayu lapis nasional., By using a simultaneous equation model which links plywood industry with log industry, demand for plywood in domestic market and export market, and supply of and demand for plywood in the world market, this study aims to analyze factors affecting the development of Indonesia's plywood industry and its prospects in the period of2000-2010. Results of estimation show that the behavior of log production is significantly affected by exchange rate of rupiah to US dollar, depreciation of rupiah to US dollar will be followed by increasing log production. Indonesia's production of plywood is dependent on the number of log and level of processing technology used. Simulation results indicate that economic crisis in Indonesia since the middle of 1977 which depreciates exchange rate of rupiah to US dollar drastically, the withdrawal of policy to ban log export in 1998 in accordance with the Government of Indonesia commitment with IMF, the immediate imposition of ecolabelling, the gradually declining of import tariff for plywood by importing countries, and the advancement of processing technology which improve the productivity of plywood industry will cause an increase in log production. As the demand for log by the plywood industry remains relatively constant, this means that most of the increase in log production will go to export market which offers higher ,prices than the domestic market. One has to be on the alert with this possibility since it has the potency to threat the sustainability of national production forest and, of course, the prospect of Indonesia's plywood industry.
