PERTUMBUHAN TANAMAN GAHARU Aquilaria spp DENGAN PEMBERIAN MIKORIZA DAN MULSA PADA LAHAN TERBUKA DI TANAH ULTISOL
Get PDFAgarwood (Aquilaria spp) only can be grown under shade on the first phase of planting because this plant has silvic semi tolerance. This condition make agarwood difficult to grow under open field. Due to this condition, to grow in open field, arbuscular mycorrhizal fungi and mulching are needed. The research work aimed to find the effect of mycorrhizal fungi and mulching on agarwood growth in open field. The research work was conducted in experiment garden of Universitas Tanjungpura in Pak Laheng village, Toho district, Mempawah regency until the plant aged 8 weeks. The research work employed split plot design using a randomized block design. The treatment consisted of main factor with seedling without fungi (A1) and seedling with fungi (A2) and additional factor with plant without mulching (B1) and plant with mulching (B2). The research findings showed that in the age 8 weeks the mycorrhizal fungi only could fasten the growth of diameter and while mulching had effect on height, diameter and number of leaves. The interaction of these two treatment gave significant impact on diameter and number of leaves. Keywords : Aquilaria spp, Arbuscular Mycorrhizal Fungi and Mulching, Open Field and Ultisol Soi
IDENTIFIKASI JENIS TUPAI (Tupaia Sp.) DI HUTAN TEMBAWANG DESA MENSIKU BERSATU KECAMATAN BINJAI HULU KABUPATEN SINTANG
Get PDFForest ecosystem and flora and fauna variety are a basic capital for national development which benefit for human’ s life in particular at Tembangan forest located in Mensiku Bersatu village of Binjai Hulu sub-district of Sintang. Tembangan forest located in Mensiku Bersatu village of Binjai Hulu sub-district of Sintang has a lot of flora and fauna and one of its familiar animals is squirrel. For several reasons, squirrel conservation is considered as an unimportant action since this wild animal is often regarded as one of potential pests. In fact, squirrel has several significant roles in maintaining the sustainability of forest ecosystem since this animal can perform as a flora distributor or a insect controller that distribute seeds around Tembangan forest. The purpose of this study is to investigate the type of squirrel species at Tembangan forest located in Mensiku Bersatu village of Binjai Hulu sub-district of Sintang. The study result is expected to have significant contribution regarding the required data for management, protection, and conservation of Tembangan forest. The setting of this study is in Tembangan forest located in Mensiku Bersatu village of Binjai Hulu sub-district of Sintang. Survey method and purposive sampling technique are applied in this study to identify the squirrel’s main territory around Tembangan forest. Based on the results of observation and identification, it can be concluded that Tembangan forest located in Mensiku Bersatu village of Binjai Hulu sub-district of Sintang has 5 species of squirrel specifically Spotted Squirrel (Tupaica picta), Slim Squirrel, (Tupaica gracilis), Small Squirrel (Tupaica minor), Javan Treeshrew Squirrel (Tupaica javanica),and Beautiful Squirrel (Tupaica splendidula). There are approximately 183 squirrels living in Tembangan forest and Spotted Squirrel (Tupaica picta) is the most common type of squirrel found in there and Tembangan forest has 82 spotted squirrel (Tupaica picta), 36 slim squirrels (Tupaica gracillis), 45 small squirrels (Tupaica minor), 13 Javan Treeshrew Squirrel (Tupaica javanica), and 7 beautiful squirrels (Tupaica splendidula).

EFEKTIFITAS CAMPURAN DAUN KAYU PUTIH (Melaleuca eucadendra) DAN LIMBAH KERTAS HVS SEBAGAI BIOATRAKTAN PADA RAYAP TANAH (Coptotermes sp)
Get PDFAt recent year, termite control strategies is still using of synthetic termiticide which is applied either by soil treatment, wood preservation or impregnation of the thermiside into the target. This control technique is very effective and beable to protect buildings and agricultural crops from termite attack, on the other hand, synthetic termite can pollute the environment and potentially poison to human. Therefore, it is necessary to develop termite control technology using baiting system, which is made from natural material as environmentally friendly. Eucalyptus leaves are potentially used as attractants for termite control by bait method. The test was conducted in two methods: no-choice test and two-choice test, using 5 treatment composition, eucalyptus leaves: official waste paper, 80%: 20%, 60%: 40, 40% : 60%, 80% : 20%, and 0% : 100% as control. The results showed that the mixing of eucalyptus leaf (Melaleuca leucadendra) and official waste paper at composition of 60%: 40% was effective as bioatractant to termites (Coptotermes sp).

SUKSESI VEGETASI PADA LAHAN BEKAS PENAMBANGAN EMAS RAKYAT DI KECAMATAN MONTERADO KABUPATEN BENGKAYANG
Get PDFThis study aims to obtain information about the succession levels of natural vegetation on ex – community gold mining in Monterado. The method of this research was survey method through vegetation analysis by double plot size 20 m x 20 m. Placement of plots dileberately based on the tailing period of ex – community gold mining which were : 10 years. The result showed that kinds of shrub found in all age level of ex – community gold mining area. The type of woody plants at the seedling found in all period of ex – community gold mining area, whereas sapling, pole and tree only found in ex – community gold mining at age level > 10 years. Based on the vegetation analysis, it showed that Ischaemum rugosum and Melastoma malabathricum L. dominanted at all age level of ex – community gold mining. Seedling in the ex – community gold mining at all age level were dominanted by Dillenia suffruticus. The index of species diversity showed that it was still low on ex – community gold mining in Monterado.Until the age of tailing > 10 years, succession was still in the level of competition, so it was concluded to be slow. To accelerate succession, revegetation, land restoration, and people awareness should be undertaken.Keyword : Gold mining, Monterado Sub district, Succession

ANALISA BIAYA DAN PENDAPATAN INDUSTRI PENGOLAHAN KAYU DI KABUPATEN KUBU RAYA
Get PDFWood furniture industry is one of the wood industries in the district of Kubu Raya, West Kalimantan Province. The industry has long existed and has to compete with other local furniture industry. The objectives of this study is to investigate the cost of each manufacture unit and actual income of each production type, analyze the economic income, indentify the amount of production break-even point and break event point of each production unit since West Kalimantan forests have sufficient raw material of wood for furniture production. The average cost of door production is 293.111 rupiah per unit,the average cost of window production is 141.045 ruiah per unit and the average production cost of sills is 134.053 rupiah, actual profit of door production is 41.731 rupiah per unit, actual profit of window production is 49.536 per unit and actual income of sills production amounted to 105.947 per unit, break even point rupiah for door production amounted to 334.828 rupiah, break even point rupiah of window amounted to 190.581 rupiah and break even point rupiah of sills amounted to 240.000. The findings indicate that the furniture industry is the industry that is highly helpful in increasing the incomes of enterpreneurs. Therefore, many people are interested. Community needs in the use of furniture production is increasing and the limited availability of raw materials make the selling price to be expensive. Accordingly for the furniture enterpreneurs should have sufficient supplies of raw materials in the warehouse.
