Abstract

Timber harvesting activities in forest concession using the Indonesia Selective Cutting and Planting silvicultural (ISCP) system can cause damage to residual trees. The greater the damage of residual trees to be indicator the less effective the activity. This study aims to determine the damage of residual trees caused by harvesting in the logged-over areas using the ISCP silvicultural system. The study used a research plot measuring 40 m x 240 m (0.96 ha) with 5 replications. Each research plot was consisted of 24 sub plots each for the trees, pole, sapling and seedling levels. Sample felled trees were determined as many as 30 trees. The results showed that the average damage caused by harvesting of 1 tree was 6.46 seedlings/ha; 7.17 saplings/ha; 2.13 poles/ha and 2.25 trees/ha. In general, the damage to residual trees due to felling was 11.28% for seedlings; 11.56% for saplings, 12.14% for poles and 11.8% for trees. The level of damage to seedlings, saplings and poles were in the medium category, while the level of damage to the tree level was in the low category.

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

The aim of the study was to determine the effect of a combination of mycorrhizal fungi and watering intervals on kayu kuku (Pericopsis mooniana) grown on gold tailings media. This research was conducted at the green house of the Indonesian Mycorrhizal Association (AMI) Southeast Sulawesi branch for 4 months (March-July 2019). The study used a factorial randomized block design (CRD) with two factors being tested, the first factors including no AMF inoculation, using Claroideoglomus etunicatum and Septoglomus constrictum which were given 10 grams each. The second factor included watering every day, every two days and every three days, with three replications and three crop units. The results showed that the treatment combination of AMF type S. constrictum with daily watering intervals increased P nutrient levels on the shoot and root, while three days watering intervals increased Mn uptake on the shoot. The combination of AMF treatment for C. etunicatum and daily watering intervals increased the Mn level of the roots and the two days watering interval increased the P uptake on the shoots and roots. The best treatment was a combination of AMF type C. etunicatum and two days watering intervals which effectively increased P uptake of the shoot. Independently, AMF treatment for S. constrictum and two days watering interval were effective in increasing the levels and P nutrients uptake on the shoot. Keywords: Drought stress, Arbuscular Mycorrhizal Fungi, Pericopsis mooniana, uptakeof nutrients.

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 research aims to (1) analyze the pattern of ecotourism management in Gili Lawang based on the concept of CBT (Community based tourism) according to Demartoto (2009) and (2) analyze supporting and inhibiting factors that affect the involvement ofcommunity in managing ecotourism. The research was located in Gili Lawang ecotourism area, Sugian Village, Sambelia, East Lombok Regency. This research used descriptive qualitative method, by using literature reviews data collection method,interviews, and observations. The number of respondents involved were 14 respondents. Data analysis that was used is descriptive analysis. The result of this research showed that the management pattern of community based ecotourism in Gili Lawang has not fully implement CBT (Community based tourism) concept since the involved community has not been included in evaluator aspect. Supporting factors that affect the involvement of the community in managing ecotourism is the potential of tourism that can be developed into tourism attraction, the desire of the community to preserve the nature, and to grow the economy surrounding the tourism area. Meanwhile, the inhibiting factor that affect the involvement of the community in managing ecotourism is the lack of education of the community regarding the development of ecotourism area and the lackof awareness of the community regarding the importance of their involvement in developing tourism area. Besides that, another inhibiting factor is the lack of government’s concern to make approach to the native community to show how importantcommunity based tourism is.Keywords: Ecotourism, management pattern, involvement factor
