Judul: Impact of forest royalty and reforestation fund on welfare
Abstrak: Dalam tiga dasawarsa terakhir sektor kehutanan memberikan kontribusi penting bagi perekonomian Indonesia. Kontribusi penerimaan pemerintah dari sektor kehutanan diantaranya bersumber dari Provisi Sumberdaya Hutan (PSDH) dan Dana Reboisasi (DR). PSDH dan DR dihitung atas dasar jumlah kayu bulat yang dihasilkan dari hutan alam dan hutan tanaman. Untuk mempertahankan keberlanjutan kontribusi tersebut maka diperlukan kepastian penyediaan bahan baku kayu bulat yang berkelanjutan bagi kebutuhan industri berbasis kayu. Tujuan dari penelitian ini adalah untuk (1) menganalis model penawaran dan permintaan kayu bulat melalui estimasi elastisitas supply dan demand pada pasar input kayu bulat dan pasar output produk primer kayu olahan, (2) menganalisis dampak kebijakan PSDH dan DR terhadap produksi, dan harga kayu bulat serta kayu olahan, dan (3) menganalisis berbagai skenario kebijakan PSDH dan DR dan dampaknya terhadap kesejahteraan produsen dan konsumen. Model persamaan yang digunakan untuk mendapatkan parameter dugaan dalam penelitian ini adalah persamaan simultan atau Two Stage Least Squares (2SLS) dan persamaan tunggal atau Ordinary Least Squares (OLS), sehingga diperoleh nilai parameter terbaik, yang merupakan penduga elastisitas. Dalam penelitian ini akan dicari estimasi model pasar input, pasar kayu bulat, yaitu kayu bulat dari hutan alam, kayu bulat dari HTI perkakas dan kayu bulat dari HTI pulp sebagai bahan baku industri pimer dan pasar output, yaitu pasar kayu lapis, kayu gergajian dan pulp. Data yang digunakan dalam penelitian ini adalah data time series dari tahun 1995 sampai dengan tahun 2009, diolah dengan menggunakan program statistik komputer RATS (Regression Analysis of Time Series).

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.
