KEANEKARAGAMAN JENIS ROTAN DI KAWASAN HUTAN ADAT SEPORA DESA KASROMEGO KECAMATAN BEDUAI KABUPATEN SANGGAU
Get PDFIn the wood is complex structure creates an environment that is, allowing the diversity and plants to live within. One of the diversity that can grow in the woods Indonesia is rattan. Wicker including the typical tropical belonging to the family palmae (Dransfield and Manokaran 1996 in Jumiati et al, 2012). In the woods customary Sepora there have been a number of rattan. It can be seen from surrounding the use of these plants as the rattan, wicker rattan, mat, wicker vegetables, basket, the material and forth. The types of rattan is in an area of forest customary Sepora had not yet been attention so that infomation about the types of rattan not yet avaible. The purpose of this study is to find the diversity of spesies in the industry, wicker especially a kind of which is generally usedby the community and rattan supplies as feedstocks. Of the field observation finding of rattan derived of the genus, calamus, korthalsia and daemonorops. Of the six flavors of the raw materials only one kind of rattan a solitary namely of the genus calamus. Based on analysis obtained diversity field index to spesies (Hʹ) ranges from 0,0642-0,1530, or less than one which means that the diversity of the species in this area relatively low. While the dominant index value (C) of 0,0024-0,0708, or less than one showing that the absence of distinction from one species with other species within to community, to achieve that in a community has an equal chance of good growing.

KUALITAS PEWARNAAN KAYU SENGON (PARASERIANTHES FALCATARIA (L). NIELSEN) DENGAN MENGGUNAKAN EKSTRAK KULIT BUAH MANGGIS, KULIT KAYU AKASIA DAN KULIT KAYU BAKAU
Get PDFThe usage of wood is not limited to household appliances but also used wood for the exterior. Wood have a high decorative value because of its color and fiber pattern. Wood decorative value increase the economic value of wood. Sengon (Paraserianthes Falcataria (L). Nielsen), one of wood species which not have interesting pattern and color thus through this research dyeing process conducted to know the optimum concentration of Sengon staining by using several natural extract such as the rind of Mangstosteen fruit (Garcinia mangostana L.), bark of Acacia mangium and Mangrove tree bark. There were four level of concentration used 5%, 10% , 15% and 20%. The result showed that the highest extract yield percentage derived from A. mangium bark followed by mangrove bark and mangoosten fruit rind (32.67%, 29.09% and 28.37 respectively). While for pH value, mangoosteen fruit rind extract have the highest value followed by mangove bark extract and A. Mangium bark (5.8-6, 5-7 and 5-5.2 respectively). The highest absorbance value derived from A. Mangium bark extract followed by mangosteen fruit rind extract and mangrove bark extract (0.715 ppm, 0.476 ppm and 0.439 ppm respectively). A. Mangium bark extract also shown the highest absorbance followed by mangrove bark extract and mangosteen fruit rind (0.699 ppm, 0.477 ppm and 0.4 ppm) in 478 nm wavelength with 800C. Dyeing process with mangosteen fruit rind extract with 20% concentration resulted highest retention value (9.064 kg/m3) while for the brightness resulted from 10% concentration.

Get PDFThe Tawang Panyai Customary Forest has various species of trees which produce timber, fruits, medicinal plants, rattan and bamboo used by the indigenous De’sa Dayak people around it. To date, the Tawang Panyai Customary Forest is well preserved through local wisdom of the local community. This research aims to find out the forms of local wisdom and describe how such wisdom in the community preserve the Tawang Panyai Customary Forest in the village of Tapang Semadak in Subdistrict of Sekadau Hilir, Sekadau Regency. The research findings show that there are six forms of local wisdom in preserving the forest i.e. prohibition on felling / stealing trees in the forest, prohibition on taking or killing animals, prohibition on opening the customary forest for farming, myth/belief about bunyik (ghost), traditional rituals of badarak, maintaining good attitude and speech.

STUDI LAJU KONSUMSI UMPAN RAYAP COPTON 0.5 RB DALAM PENGENDALIAN RAYAP COPTOTERMES CURVIGNATHUS HOLMGREN PADA PERKEBUNAN KELAPA SAWIT ELAEIS GUINEENSIS JACQ
Get PDFOil palm plantations in West Kalimantan are located in an area dominated by peat soils. This condition makes oil palm trees vulnerable to subterranean termite attack. Coptotermes curvignathus Holmgren currently has become one of major key pest of oil palm. These termites attack the oil palm trunk, crown, fronds and fruits. Current practice of Termite control in oil palm is by direct spraying chemical pesticides, but this type of treatment proves uneconomical and hostile to the environment. In addition, chemical sprays are ineffective due tothe termite nest is below ground and the pesticide does not reachthe termites inside the nest. Therefore a new paradigm, such as baiting systemwhich the objective for termite colony elimination are needed to control termites in oilpalm plantation. This study aimed to evaluate the effectiveness of Copton 0.5 RB containing the active ingredient hexaflumuron 0.5% to control Coptotermes curvignathus in oil palm plantation at mature oil palm. Four blocks of an oil palm plantation with severe termite damage was chosen as test site. In each block consisted of four oil palm trees and one bait was place at one tree within each block. Monitoring was conducted every seven days for one month, and after that bait consumption and colony elimination were analyzed. The results showed average bait consumption value was 96.87%.The bait consumption activities start from seven days after installation. 1st monitoring showed good palatability that the termites consumed 13 from 16 baits. The consumption began to decline at the end of the fourth week. It was assumed that the baits were eliminatethe termite colony. The decline in termite attack in the oil palm trees was first observed with drying of the termite shelter tubes and by no termites inside the oil palm fronds. It is concluded that Copton0.5RB (hexaflumuron 0.5%) is effective for colony elimination of Coptotermescurvignathusin oil palm plantations.

PENGARUH FREKUENSI PEMBERIAN DAN DOSIS PUPUK ORGANIK AIR TERHADAP PERTUMBUHAN DAN INDEKS MUTU BIBIT GAHARU (AQUILARIA MALACCENSIS LAMK) DI PERSEMAIAN
Get PDFAquilaria malaccensis Lamk is one of the agarwood-producing plants have high economic value and low populations in the natural forest. Since 2004 CITES sets of this type in Appendix II and the needed multiplication of the species. This study aimed to obtain information about the frequency and dosage which was optimum for the growth of seedlings of A. malaccensis. Giving of liquid organic fertilizer is expected to increase the growth and Seedling Quality Index (SQI) A. malaccensis. This research was conducted using a Completely Randomized Design (CRD) with two factors, namely the frequency of fertilizer (a1: 10 days, a2: 15 days and a3: 20 days) and dozis of fertilizers (b0: 0 cc / l of water, b1: 2.5 cc / l of water, b2: 5 cc / l of water and b3: 7.5 cc / l of water). Parameters measured were height, leaf number, diameter, fresh weight and dry weight of seedlings. The results showed that the frequency and dosage of fertilizers provide a good influence on the growth of seedlings of A. malaccensis and same with the seed quality index. The frequency of the best fertilizer is 10 days (a1) with a dose of fertilizer 2.5-5 cc / l of water (b1 and b2). Keywords : Aquilaria malaccensis, liquid organic fertilizer, agarwood
