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.

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.

Gastropods are a single shell mollusk phylum. Gastropods have a really significant function, particularly in the mangrove ecosystem. Mangrove forests are a very supportive habitat for gastropods. Gastropods have a very important role in the processof decomposing litter and maintaining nutrient dynamics in mangrove forests. This study aims to obtain and analyze data on the diversity of gastropods in the mangrove forest ecosystem in Sentebang Village, Jawai District, Sambas Regency. The research wasconducted in June 2020 using survey methods and data collection techniques using purposive sampling. Based on the results of the research that has been done, it was found that there were 11 types of gastropods from 5 families. The types of gastropods found were Nerita violacea, Cerithidea obtusa, Cerithidea cingulata, Littoraria melanostoma, Littoraria scabra, Littoraria angulifera, Pythia plicata, Ellobium aurisjudae, Cassidula nucleus, Cassidula aurisfelis, Spherassiminea miniata. The gastropod diversity index in line 1 = 1.2246, line 2 = 0.8689, and line 3 = 0.9554. Track 1 is in the medium category, for lines 2 and 3 it is in the low category. The overall diversity index is 1.6239 which is in the medium category. The similarity index for the types of gastropod lines 1 and 2 = 40%, lines 2 and 3 = 25%, lines 1 and 3 = 20% which are included in the low category.

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
本研究旨在(1)根据Demartoto(2009)基于CBT (Community based tourism)概念分析吉利拉旺生态旅游管理模式;(2)分析影响社区参与生态旅游管理的支持和抑制因素。研究地点位于东龙目岛Sambelia Sugian村的Gili Lawang生态旅游区。本研究采用描述性定性方法，采用文献综述法、资料收集法、访谈法和观察法。涉及的回答者数目为14人。使用的数据分析是描述性分析。研究结果表明，由于所涉及的社区没有被纳入评价方，吉利拉旺社区生态旅游管理模式没有充分贯彻CBT (community based tourism)理念。影响社区参与管理生态旅游的支持因素是旅游可以发展成旅游景点的潜力，社区保护自然的愿望，以及发展旅游区周围的经济。同时，影响社区参与生态旅游管理的抑制因素是社区对生态旅游区开发的教育不足，社区对其参与旅游区开发的重要性认识不足。除此之外，另一个抑制因素是政府缺乏关注，以接近当地社区，以显示社区为基础的旅游是多么重要。关键词:生态旅游，管理模式，介入因素

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","PeriodicalId":42714,"journal":{"name":"Jurnal Manajemen Hutan Tropika","volume":"4 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2022-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85265684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
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
广藿香(Pogostemon)可以生长在干燥的土地上，并生产atsiri油。土地常常干燥，经历干旱但广藿香却能存活，广藿香对生活在干旱胁迫条件下的适应性有趣，探讨其原因。本试验旨在探讨广藿香品种适应干旱胁迫的形态生理特征。试验采用随机完全设计，共4个重复。将5个广藿香品种(Aceh Merah, Lhokseumawe,Tapak Tuan, Sidikalang和Girilaya)移栽到30 x 15 x 90 cm的木盆中，并在移栽后进行较少的水处理以启动干旱胁迫，所有盆均被水饱和(直到100%田间容量)，然后在移栽后120天(DAT)进行无水处理。观察参数为:生长和产量、叶片生物量和脯氨酸含量。结果表明，吉莱拉娅和塔巴克团品种的生长和生物量产量最高;而Sidikalang品种的生产力最低。根长、根鲜重和叶片脯氨酸含量均以吉日拉雅最高，其次为塔巴克团。对爪哇广藿香(Pogostemon haeyanus Benth)品种的生长、生产和形态生理特征及其对干旱胁迫的适应水平的分析表明，吉里拉雅(Girilaya)对干旱胁迫的耐受性最强。而在亚齐广藿香类群(Pogostemon cablin Benth)中，Tapak Tuan是最耐受性的品种。关键词:适应，广藿香，形态生理特征，干旱胁迫

The research was conducted in October 2019 in the Bukit Tangkiling Nature Reserve, Central Kalimantan, aiming to find out the type composition, the community structure, and vegetation diversity. This research method is a survey with combination method and carried out purposively in sampling with total sample plots of 60. The results showed that there were 58 species of plants (6 species unidentified) which included 11 species of understorey, 32 species of seedlings, 32 species of saplings, 31 species of poles, and 38 species of trees. Vegetation at the level of seedlings, saplings, poles, and trees in the Bukit Tangkiling Nature Reserve is dominated by Acacia mangium, while the understorey is dominated by nut grass and thatch. The similarity index of vegetation communities between two locations ranged from 41.860 - 73.684%, while that between growth rates ranged from 32.558 - 7.143%. Plant communities have diversity values (H’), richness values (R), and evenness values (E) ranging from low to moderate. The horizontal stand structure has different exposed diameters, forming an inverted “J” curve and is concentrated in diameter class 1019.99 cm, while vertically the individual population is concentrated in high class 5 - 9.99 m.Keywords: Composition, Heterogeneity, Similarity, Stand structure

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.
