Judul: Analisis penawaran dan permintaan kayu bulat: kebijakan pengaturan bahan baku untuk industry pengolahan kayu primer
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: Analisis Faktor-Faktor yang Memengaruhi Penawaran Kayu Bulat Hutan Alam di Indonesia
Abstrak: Kayu merupakan hasil utama yang diambil dari hutan, yang dapat berupa kayu bulat dan kayu olahan. Sejak awal, pembangunan sektor kehutanan lebih terkonsentrasi pada industri kayu bulat dikarenakan produk ini merupakan produk utama sektor kehutanan yang menjadi tombak penghasil devisa. Untuk meningkatkan industri pengolahan kayu serta untuk mengatasi permasalahan deforestasi, pemerintah telah mengeluarkan beberapa kebijakan pengelolaan hutan, di antaranya adalah kebijakan larangan ekspor kayu bulat. Pengembangan industri kayu bulat dalam negeri di Indonesia harus didukung oleh pemerintah sehingga dapat terus berjalan dengan baik. Tujuan penelitian ini adalah: (1) menganalisis faktor-faktor yang berpengaruh pada penawaran kayu bulat hutan alam di Indonesia, dan (2) menganalisis dampak kebijakan pelarangan ekspor kayu bulat dan skenario peningkatan jumlah ekspor kayu bulat serta skenario peningkatan Provisi Sumberdaya Hutan (PSDH) dan Dana Reboisasi (DR) terhadap penawaran kayu bulat hutan alam di Indonesia. Penelitian ini menggunakan data time series tahun 1995 – 2011. Spesifikasi model penawaran kayu bulat hutan alam terdiri dari 3 persamaan (2 persamaan struktural dan 1 persamaan identitas), dianalisis menggunakan model ekonometrika dalam bentuk persamaan simultan dan diestimasi dengan mengggunakan metode estimasi Two Stage Least Square (2SLS). Hasil penelitian menunjukkan bahwa produksi, ekspor, dan inventarisasi stok kayu bulat hutan alam merupakan faktor-faktor yang memengaruhi penawaran kayu bulat hutan alam Indonesia. Peningkatan PSDH dan DR akan meningkatkan produksi dan penawaran kayu bulat hutan alam Indonesia. PSDH dan DR perlu dipertahankan demi terus memotivasi perusahaan dalam melakukan kegiatan bisnis hasil hutan yang sehat dan agar pemerintah juga mendapat jaminan penerimaan jangka panjang.
