Abstract

Patchouli (Pogostemon) can live in dry land and produce atsiri oil. Dry land often,experiencing drought but Patchouli can survive , Adaptability patchouli for life in drought stress condition interesting to ivestigate the cause. The aim of this experiment looking for morpho-physiological characteristics of patchouli varieties adaptive to drought stress condition. The experiment with A Randomized Completely Design with four replicates was used in the trial. Five varieties of patchouli namely Aceh Merah, Lhokseumawe,Tapak Tuan, Sidikalang and Girilaya were transplanted into 30 x 15 x 90 cm wood pot and treated with less water to initiate drought stress after transplanted, all pots were saturated with water (until 100% field capacity), and then treated with nowater addition up to 120 days after transplanting (DAT). Parameters observed were: growth and production biomass and proline content in leaf. The results showed that the highest growth and biomass production components were performed by Girilaya andfollowed by Tapak Tuan varieties. While Sidikalang variety was the lowest in productivity. Maximum length of root, fresh weight of root, and proline content in leaf were also found at Girilaya and followed by Tapak Tuan. Data collection on the growth, production, and morpho-physiological characteristics in relation to adaptation level to drought stress indicated that Girilaya, a Java patchouli group (Pogostemon haeyanus Benth), was the most tolerant among varieties tested. While among the Aceh patchouli group (Pogostemon cablin Benth) Tapak Tuan was the most tolerant variety.Keywords : Adaptation, Patchouli, morpho-physiological characteristic, drought stress

Abstract

Wood processing industry waste consists of waste produced by the plywood industry, sawing and woodworking consisting of ends, blades, peelings, chips and sawdust. The use of wood waste is not utilized by the furniture industry and one of the solutions to its utilization by processing wood waste into activated charcoal. Activated charcoal can be made from all carbon-containing materials both organic and inorganic provided that the material is porous. Bangkirai, Rengas and Sengon wood waste as materials used in this study were carbonized first then activated charcoal. The quality test of activated charcoal carried out includes yield, air content, ash content, volatile matter content, carbon content, absorption of benzene, absorption of iodine and absorption of methylene blue. Overall, the results of testing the quality of activated charcoal did not all meet the requirements of SNI 06-3730-1995. The quality of activated charcoal from Rengas wood has the best quality (>456.59 mg /g) of all needs because the highest iodine absorption capacity according to Kimia Farma (KF) standards requires (> 426.5 mg/g). Rengas wood activated charcoal to bore wells improves the quality of drinking water No. 416/ Menkes / Per/IX /1990 except turbidity. Keywords : Active Charcoal, Bangkirai Wood Waste, Rengas, Sengon, Drilled Well Water.

Abstract

Macaranga gigantea was one of the pioneer species who started the succession process after the forest fires and grew as dominant species. Therefore, the information on the spatial distribution pattern of M. gigantea is required as necessary data to determine the strategy for managing forest after forest fires. This study aimed to map out of distribution and identified the spatial distribution pattern of M. gigantea. Spatial analysis was to mapping out the location of M. gigantea distribution using remote sensing technology. Vegetation analysis was done by setting up a quadratic method in a square-shaped observation plot in 100 m track and then put into the location of the spread of M. gigantea by a purposive sampling method. The result showed that the spatial pattern of M. gigantea distribution tends to clump. The spatial pattern tends to clumped caused by thesimilarity of life needs between individuals, especially for light. Keywords: Pioneer species, spatial distribution pattern, composition and structure of vegetation

Abstract

This study aims to identify the species composition and estimate the potency for biomass, carbon and carbondioxide (CO2) uptake of understorey at a peat depth of 1 - <2 m; 2 - <4 m; 4 - <8 m and 8 - <12 m in Sebangau National Park Central Kalimantan. The results showed that the total number of understorey species found in all peat depths was 21 species. The most common understorey species found were at peat depths of 4 - <8 m, with 13 species. Several understorey species that dominate the entire peat depth are Pandanus tectorius, Pandanus amaryllofolius and Stenochlaena palustris. The potency of understorey biomass, carbon storage and CO2 absorption in all peat depths ranged from: 1.73 to 2.71 tons/ha; 0.81 - 1.30 tonC/ha and 2.98 - 4.77 tonsCO2/ha. Understorey that grows at a peat depth of 4 - <8 m has the highest potency for biomass, carbon and CO2 absorption.Keywords: biomass, carbon, carbondioxide, peat swamp forest, understorey

Abstract

The waste of wood processing industry such as the plywood, sawmill and woodworkingindustries give waste as form of end pieces, slash, peeling residue, scrap and sawdust.The wood waste is not utilized by the furniture industry. The solution of this problem isto process these wood waste into activated charcoal. Activated charcoal can be madefrom any material containing carbon, both organic and inorganic, provided that thematerial is porous.The first,the waste wood of Ulin, Benuas, and Agathis used asmaterials in this study were carbonized and then made into activated charcoal. Thequality test of activated charcoal were yield, moisture content, ash, volatile matter, fixedcarbon, absorption of benzene, absorption of iodine and absorption of methylene blue.Overall, not all research treatments on the quality of activated charcoal fulfill to SNI 06-3730-1995. The quality of Agathis wood activated charcoal has the best quality (520,83mg/g) from all treatments by the highest score of iodine absorption (Kimia Farma (KF)standard requires >426.5 mg/g). Based on the standar of drinking water quality No.416/Menkes/Per/IX/1990, activated charcoal of agathis wood can improve the quality ofbore well water except for turbidity.Keywords: Activated charcoal, ulin, benuas, agathis, bore well water

Abstract

This study aims to determine the social capital of the community in village forestmanagement in the Tangkahen Village area, Pulang Pisau Regency. Data retrieval using thesnowball sampling method, which means the researcher stops looking for additionalinformation when there is no more new information. The results showed that the cumulativesocial capital characteristics of the Tangkahen Village community in managing their villageforest were in the high category. The role of each element of community social capital,namely: elements of trust, social norms, pro-active actions and concern for others and theenvironment are included in the high category, only the social network element has a role inthe medium category. Activities in village forest management that have been carried out areidentifying the potential of village forests, building tree houses for natural ecotourismpurposes and marketing (promotional) activities.Keywords: Social capital, village forest management, village forest
