Judul: Penyusunan alat bantu inventarisasi hutan menyeluruh berkala (IHMB) pada IUPHHK-HA PT Austral Byna Kalimantan Tengah
Abstrak: Hutan memegang peranan penting dalam menopang sistem kehidupan di muka bumi. Oleh karena itu, diperlukan kegiatan pengelolaan hutan yang sehat dan lestari. Pengelolaan hutan yang sehat membutuhkan adanya data dan informasi yang memadai (handal, akurat, dibutuhkan, standar, tidak berbias dan dapat diakses). Berdasarkan Peraturan Pemerintah Nomor 6 Tahun 2007 tentang Tata Hutan dan Penyusunan Rencana Pengelolaan Hutan, serta Pemanfaatan Hutan, para pemegang Izin Usaha Pemanfaatan Hasil Hutan Kayu dalam Hutan Alam (IUPHHK-HA) dan Izin Usaha Pemanfaatan Hasil Hutan Kayu dalam Hutan Tanaman (IUPHHK-HT) diwajibkan menyusun Rencana Kerja Umum Pemanfaatan Hasil Hutan Kayu sepuluh tahunan (Pasal 73 dan 75 Peraturan Pemerintah Nomor 6 Tahun 2007) yang disusun berdasarkan inventarisasi hutan berkala sepuluh tahunan yang selanjutnya disebut sebagai Inventarisasi Hutan Menyeluruh Berkala (IHMB). Penelitian ini bertujuan untuk melakukan penyusunan alat bantu IHMB guna memperlancar kegiatan IHMB PT. Austral Byna, dalam hal ini adalah penyusunan Tabel Tinggi, Tabel Volume, dan Tabel Berat Pohon yang disusun berdasarkan data pohon contoh dengan menggunakan regression analysis methods. Alat bantu IHMB yang berupa tabel tinggi, tabel volume, dan tabel berat ini dapat digunakan dalam kegiatan IHMB pada IUPHHK-HA PT. Austral Byna sehingga dapat memudahkan dan mempercepat pelaksanaan kegiatan IHMB di perusahaan tersebut. Kata kunci: hutan alam, pengelolaan hutan yang sehat dan lestari, IHMB, alat bantu IHMB.

Judul: Inventarisasi Hutan Menyeluruh Berkala dalam Pengelolaan Hutan Produksi di Indonesia (Studi Kasus di Provinsi Papua)
Abstrak: The availability of data and information of forest resources plays an important role to determine the direction and clear targets in forest management at forest management unit (FMU) level. In order to preserve sustainable forest management at the sites level, management plans should be set with consideration of the entire ecosystem landscape while maintaining biological diversity and productivity as well as regeneration ability in sustaining life and potential to fulfill functions of the ecological, economic and social for current time and the future. The periodic comprehensive forest inventory (Inventarisasi Hutan Menyeluruh Berkala called IHMB) is Indonesian forest stands inventory were based on compartment at forest effective area of forest management unit (FMU). The purpose of this study is to get information about the suitability and accuracy of the IHMB implementation results to arranging long-term forest management plans (rencana kerja usaha pemanfaatan hasil hutan kayu pada hutan alam called RKUPHHK-HA) in order to forest management that aims to produce sustainable timber. Data gathered with purposive sampling technique with location consideration is the FMU that have been implemented of IHMB and the results has been evaluated and verified by the Ministry of Forestry and Forestry Provincial Office. Sampling plot of IHMB is carried out with consideration: forest cover stratification, accessibility, time and cost. The results of IHMB implementation that contain the availability potentially standing stock and other general information can not be uses as a basis to preparing a forest management plan with the aims of generating sustainable timber with the sustainability forest principles. At the FMU level, the long-term forest management (RKUPHHK-HA) which contains goals and objective of the activity that based on comprehensive data and information covering the aspect of ecological, economic and social. The sense of word “comprehensive” on IHMB is meaningfully only covered the forest area, without including all components of the data and information on forest ecosystem. The data result of IHMB implementation is uses as a basis to arranging RKUPHHK-HA, meanwhile in the short-term forest management (rencana kerja tahunan usaha pemanfaatan hasil hutan kayu pada hutan alam called RKTUPHHK-HA) is implemented by the stage of silvicultural system (tebang pilih tanam Indonesia called TPTI).

Abstrak: The solution of Schrodinger equations with plasma Coulomb potential in spherical coordinat results solution wave function and energy plasma particle. Electron probability density at Debye length with thermal effect same as ion, which indicates plasma in neutral state. Electromagnetic waves perturbation of an electric field given to result wave function perturbation system. The probability density of plasma particle due to electromagnetic waves perturbation is the largest when an electromagnetic waves frequency 1.41 times the plasma frequency .
