Sengon (Paraserianthes falcataria (L.) Nielsen) is a major forest tree species that is widely planted by smallholders in Indonesia. Ganodema infection as red root-rot or basal stem rot is becoming a more prevalent disease causing significant tree death. This research investigates the potential of biological control agents to protect Sengon seedlings from Ganoderma attacks. In vitro tests for antagonism between two Trichoderma spp (DT38 and DT39) and five fungal isolates of Ganoderma on PDA were undertaken. Four treatments were applied to sengon seedlings: 1) without Trichoderma + without organic materials (A0B0); 2) without Trichoderma + organic materials (A0B1); 3) Trichoderma + without organic materials materials (A1B0); 4) with Trichoderma + organic materials (A1B1). Seedling height and the number of leaves was recorded.

Tracking timber on teak and teak wood products can be conducted using different methods, such as DNA finger printing, chemical composition of the wood, Near Infra Red spectra (NIR) and stable isotopes. Samples were collected from wood material and leaves in Java (9 Forest Management Units district) of Perhutani to determine: i) pattern of genetic variation within and among populations, ii) to determine the protocol for DNA extraction from wood, and iii) to study the feasibility of DNA marker for timber tracking in the field. Results show that: i) genetic variation of cpDNA (PCR-RFLP) is low, while RAPD variation is moderate, ii) there are differences in chemical composition of wood among the Forest Management Units (FMUs) of Perhutani, iii) variation of isotopic carbon and oxygen in Central and East Java were higher than from of West Java, iv) absorbtion intensity of NIR in West Java was higher than for Central and East Java, and iv) testing of DNA marker showed that genetic structure in the forest site is not significantly different from that in log yards, indicating that the timber flow is still according to the procedure. RAPD marker also is able to determine the origin of illegal timber and wood in industry without clear identity.

Penerapan Multisistem Silvikultur Pada Areal Hutan Produksi (IUPHHK) di Indonesia: Tinjauan Aspek Teknik Silvikultur

Kekayaan sumber daya hutan Indonesia telah memberikan sumbangan yang sangat besar bagi perkembangan pembangunan di Indonesia. Sejarah perjalanan pengelolaan hutan produksi secara intensif telah dimulai sejak tahun 1967 setelah dikeluarkannya Undang-Undang No. 1 tallun 1967 tentang Penanaman modal Dalam Negeri (PMDN) dan Urdang-Undang No.6 tahun 1968 tentang Penanaman Modal ASing (PMA).

Multisistem Silvikultur : Pilihan-Pilihan Usaha Atraktif dan Layak Kombinasi dalam Satu Unit Pengelolaan Hutan (Konsep Subsidi Silang Hasil Usaha Berjangka)

Kurang menariknya usaha pemanfaatan hasil hutan kayu terutama diakioatkan oleh investasi yang betjangka panjang, ketidakpastian kawasan, dan ketiadaan jaminan keamanan berusaha. Upaya untuk memperbaiki kondisi ini antara lain melalui multisistem silvikultur yang mengizinkan lebih dari satu sistem silvikultur dalam satu unit manajemen hutan. Prinsipnya harus ada subsidi silang antara blok unit silvikultur betjangka pendek ke menengah, menengah ke panjang, atau sebaliknya. Oleh karena itu, mencari kombinasi tanaman dalam satu unit manajemen usaha pemanfaatan hasil hutan kayu dan agroforestrynya menjadi penting, khususnya untuk tujuan pengembalian ekuitas dan investasi bisnis yang sehat.
