Judul: Potential of Useful Plants of HCV (High Conservation Value) Area in Palm Plantation Areas at Kapuas Hulu District, West Kalimantan Province (Case Study at PT Sawit Kapuas Kencana, PT Paramitra Internusa Pratama and PT Persada Graha Mandiri).
Abstrak: Based on the result of High Conservation Value (HCV) study, which performed by Tim Terpadu (2010a, 2010b, 2010c) in PT Sawit Kapuas Kencana (PT SKK), PT Paramitra Internusa Pratama (PT PIP) and PT Persada Graha Mandiri (PT PGM), there has been found respectively 259, 225 and 149 plant species. Nevertheless, data and information about the potential of useful plants were unknown yet. In order to support its conservation and utilization efforts, all data and information about potential of useful plants was critically required, thus this research was required. The objective of this research was to identify the potential of useful plants in palm plantation area in Kapuas Hulu district, West Kalimantan province. This research performed at Section of Plants Diversity Conservation, Department of Forest Resource Conservation and Ecotourism, Forestry Faculty of Bogor Agricultural University (BAU), library of Forestry Faculty and LSI library of BAU at April to June 2011. Collected data and information in this research included primary and secondary data. Primary data collected by observation and literature review, while secondary data collected by literature review. Result identification shows that 355 species of useful plants, which classified into 88 families, found in study area with detail: PT SKK (225 species and 77 families), PT PIP (208 species and 65 families) and PT PGM (140 species and 46 families). Useful plants, in this research, was classified into 13 groups; those are: medicine (PT SKK: 100 species, PT PIP: 60 species and PT PGM: 38 species), ornament (PT SKK: 25 species, PT PIP: 22 species and PT PGM: 9 species), aromatic (PT SKK: 12 species, PT PIP: 12 species and PT PGM: 8 species), food (PT SKK: 62 species, PT PIP: 44 species and PT PGM: 35 species), feed (PT SKK: 21 species, PT PIP: 14 species and PT PGM: 6 species), herbal pesticide (PT SKK: 4 species, PT PIP: 4 species and PT PGM: 3 species), fibre (PT SKK: 6 species, PT PIP: 5 species and PT PGM: 1 species), colour and tannin (PT SKK: 24 species, PT PIP: 17 species and PT PGM: 13 species), construction material (PT SKK: 69 species, PT PIP: 58 species and PT PGM: 35 species), traditional custom material (PT SKK: 13 species, PT PIP: 11 species and PT PGM: 10 species), rope, plait and handicraft material (PT SKK: 21 species, PT PIP: 22 species and PT PGM: 16 species), fuel (PT SKK: 23 species, PT PIP: 17 species and PT PGM: 16 species) and others (PT SKK: 21 species, PT PIP: 18 species and PT PGM: 12 species).

Judul: Potensi tumbuhan berguna pada areal HCV (High Conservation Value) di perkebunan kelapa sawit, Kabupaten Kapuas Hulu, Provinsi Kalimantan Barat (Studi Kasus di PT Sawit Kapuas Kencana, PT Paramitra Internusa Pratama dan PT Persada Graha Mandiri)
Abstrak: Berdasarkan hasil kajian High Conservation Value (HCV) yang dilakukan oleh Tim Terpadu (2010a, 2010b, 2010c) di PT Sawit Kapuas Kencana (PT SKK), PT Paramitra Internusa Pratama (PT PIP) dan PT Persada Graha Mandiri (PT PGM) di Kabupaten Kapuas Hulu, Provinsi Kalimantan Barat, ditemukan jumlah jenis berturut-turut sebanyak 259, 225 dan 149 jenis tumbuhan. Namun data dan informasi mengenai potensi tumbuhan berguna belum diketahui. Dalam rangka mendukung upaya pelestarian dan pemanfaatannya, data dan informasi tentang potensi tumbuhan berguna sangat dibutuhkan, sehingga perlu dilakukan penelitian ini. Tujuan dari penelitian ini yaitu mengidentifikasi potensi tumbuhan berguna pada areal perkebunan kelapa sawit di Kabupaten Kapuas Hulu, Provinsi Kalimantan Barat.

Judul: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
