HTI Area PT. Bhatara Alam Lestari (BAL) is one of the locations that has the potential of orchids. The efforts to conserve the use of orchid species and data collection on the types of orchids need to be done. But the lack of data and information on orchid species identification, the study identified the orchid species in the area.This study aimed to identify orchids (Orchidaceae) nature to the level of the genus. While the benefits were expected to provide information about the existence of orchid species in the protection and preservation efforts could be maintained naturally in the secondary forest IUPHHK-HTI PT. Bhatara Alam Lestari.This research used survey method with exploration and flora collection system. Length of line 500 m, path width 20 m (10 m left and 10 m right). The path was placed by purposive sampling based on the existence of orchids. The results showed 11 species of orchids with 49 individuals from seven genera: Bromheadia, Bulbophyllum, Flickingeria, Coelogyne, Dendrobium, Liparis, Plocogtottis. The largest genus found was Bulbophyllum with four species. The types of orchids found mostly grow on trees (epiphytes) namely: Bulbophyllum macranthum, Bulbophyllum purpurances, Bulbophyllum sp. 1, Flickingeria sp, Coelogyne verucosa, Dendrobium crumenatum, Liparis sp, Coelogyne sp. It was also found growing in the soil (teresterial), namely: Bromheadia finlaysoniana, Bulbophyllum sp. 2, Plocogtottis lowii.Keywords: Bulbophyllum, Epiphytes, Identification, Orchidaceae, Terrestrial

Nepenthes is one of plant species that found in Indonesian tropical forests. This plant has uniqueness and many benefits make this plant being hunted and exploited, caused the existence of its population are decreasing. Nepenthes inhabit in various conditions, one of the site is in lowland secondary forest. This study aims to find out site diversity of nepenthes in various secondary forest land cover conditions in Bukit Batu Village. This research is expected to be a baseline information on nepenthes diversity for the goal of protection and use fullness of nepenthes. This research employed survey method with purposive sampling on plot placement. Plot size was 20 m × 20 m with sub plot was of 10 m × 10 m. The results show that secondary forest of Bukit Batu Village which were varied on coverage condition, on open canopy 4 species of nepenthes were found such as N. ampullaria jack., N. bicalcarata Hook.F., N. rafflesiana Jack. and N. gracilis korth., under medium canopy coverage there was 3 nepenthes species found, which was N. ampullaria jack., N. bicalcarata Hook. F. and N. rafflesiana Jack., and under closed canopy conditions there was 2 species of nepenthes found N. ampullaria jack. and N. bicalcarata Hook. F. The results showed that only few nepenthes species found in this forest area and species nepenthes found more under open canopy condition, due to those species needed more light to survive.Keywords: Canopy Cover, Diversity, Nepenthes spp, Secondary Fores

PENGARUH PEMBAKARAN BERULANG PADA LAHAN GAMBUT TERHADAP BEBERAPA KARAKTERISTIK TANAH DI DESA RASAU JAYA UMUM KABUPATEN KUBU RAYA KALIMANTAN BARAT

The National Disaster Management Agency (BNPB) identifies eight provinces considered prone to forest and land fires in Indonesia. Four provinces are in Sumatra and four are in Kalimantan, one of which is West Kalimantan. Forest and land fires seem to have become a disaster in West Kalimantan, especially every dry season. Burning activies in the preparation of land for agriculture in the village of Rasau Jaya General is still using a relatively simple technology, namely the method of "slash and burn". The impacts caused by the peat fire process are in the form of water vapor from the combustion process in the air so that smoke formed which is very thick, causes environmental pollution and can affect soil conditions such as physical and chemical properties of peat soils. The purpose of this study was to obtain information about the effects of repeated burning on peatlands on soil characteristics in Rasau Jaya Umum Village, Kubu Raya Regency, West Kalimantan. This research was conducted by survey method and carried out with purposive sampling on 3 research sites, which were on land that had repeated burning twice, 4 times and 5 times. Soil physical properties observed were peat maturity (fiber content), water content, soil moisture, water level and bulk density. The level of fertility of peatlands is influenced by the chemical nature of the soil. The chemical nature of the soil is one of the limiting factors for knowing nutrients in the soil that are beneficial for plant growth. Determination of the level of soil fertility in peatlands can be done by analyzing the chemical properties of the soil. Analysis of the soil chemical properties includes analysis of the main element content such as acidity (pH), nitrogen (N), phosphorus (P), potassium (K) and cation exchange capacity (CEC). The physical properties of the soil consisting of the weight of the contents, the moisture content varies with different levels of burning, the higher the value of the weight of the contents, the more dense a soil and vice versa. In the value of water content, the amount of combustion influences the amount of ground water content, the more number of combustion, the value of water content also increases. Peat environmental conditions observed in the field consisted of soil moisture, soil temperature and ground water level measured for 7 days and obtained a mean value that also varied did not show its effect on the number of repeated fires. The chemical properties of peat soils on the number of repeated burning can increase and decrease each nutrient value consisting of N, P, K and also CEC. Nutrients that increase in the amount of combustion are pH, N, and CEC while the value of nutrients that decrease is K and P. This shows that the greater the level of combustion, the pH, N, and CEC greater.Keywords: peatlands, repeated burning, soil characteristic

KEANEKARAGAMAN TUMBUHAN OBAT DALAM KAWASAN HUTAN SEKUNDER AREAL IUPHHK PT. KALIMANTAN SATYA KENCANA KABUPATEN MELAWI

Forest in the area of IUPHHK (Timber Forest Product Utilization Permit) PT. Kalimantan Satya Kencana is one of the forest where located in the Melawi district that has high enough of flora diversity. The medicinal plants that is part of the biological germplasm. The purpose of this study this to determine the diversity of medicinal plants in secondary forest (slash ex 2008) at the area of IUPHHK PT. Kalimantan Satya Kencana Melawi District. This study used quadrant method with multiple plots. Purposive sampling it has chosen by observation in according to the local communities most numerous types of medical plants. There was 71 medicinal plants outside the plots founded in the observations. The dominance index (C) of the tree level = 0.108. Tree level (C) of = 0.238. Saplings (C) of = 0.83. Plant Nursery and Lower level (C) of = 0.042. Species Diversity Index (H) to the level of the tree = 1.017, for the level of the pole (H) at = 0.629, sapling level (H) at = 1.084 and lower levels, and Plant Nursery (H) at = 1.455. Wealth index type (d) at tree level of = 6.695. Pole at = 2.590 level. Of = 10,204 saplings, seedlings and undergrowth for 20,325. Abundance index type (e) at the tree level of = 0.937. Tree level index (e) of = 0.924.
