Furthermore, this study provides valuable insights that would allow us to better grasp the positive impacts of innovative policies in managing KPH.Keywords: forest management unit, nature-based tourism, social forestr
Pemodelan Spasial Kesesuaian Habitat Elang Jawa (Nisaetus bartelsi) di Taman Nasional Bromo Tengger Semeru (Spatial Modeling of Javan Hawk-Eagle (Nisaetus bartelsi) Habitat Suitability in Bromo Tengger Semeru National Park)
No full textBromo Tengger Semeru National Park (TNBTS) is a conservation area as the habitat of endemic species in Java Island, such as the Javan hawk-eagle (Nisaetus bartelsi). One of the spatial models of habitat is the Ecological Niche Modeling (ENM) approach. This study aimed to determine habitat suitability for the Javan hawk-eagle in TNBTS. The research was conducted from September 2019 to January 2020. The habitat suitability model used the present coordinate point data and the Javan hawk-eagle habitat environment variables. The data were then analyzed to build a Javan hawk-eagle habitat suitability model using the Maximum Entropy (MaxEnt) algorithm. The results showed three models of habitat suitability categories, i.e.: high of 15,131.18 ha (30%), medium 11,216.61 ha (22%), and low 23,298.41 ha (48%). The evaluation of the Javan hawk-eagle habitat suitability model in TNBTS has an excellent model accuracy with an AUC value of 0.97 and a standard deviation of 0.93.Keywords: endemic, habitat, Javan hawk-eagle, maximum entropy, spatial modelin
Efficacy of Liquid Smoke Produced from Medang Wood (Cinnamomum sp.) against Schizophyllum commune
Full text linkThe efficacy of liquid smoke obtained from medang wood (Cinnamomum sp.)against Schizophyllum commune fungus was evaluated. This study aims to evaluate the antifungal properties of liquid smoke from medang against S. commune fungus. Potato Dextrose Agar (PDA) medium was used to determine the efficacy of the liquid smoke of medang wood on S. commune fungus growth. Three kinds of liquid smoke were obtained from the pyrolysis of medang wood at 370, 400, and 430°C. The efficacy of liquid smoke from medang wood for antifungal is a factorial 3 by 4 in a completely randomized design; the first factor was pyrolysis temperature of liquid smoke from medang (370, 400, and 430°C), and the second factor was the treatment of concentration of liquid smoke from medang wood (0, 0.5, 1.0, 1.5, 2.0, 2.5, and 3.0%, v/v). The results showed that pyrolysis temperature affected liquid smoke from medang, and the concentration of liquid smoke was significantly different for inhibition of fungal growth. The results indicated that the pyrolysis temperature of liquid smoke production and the concentration of liquid smoke had a significant effect on S. commune fungus growth inhibition. Medang wood liquid smoke effectively inhibited the growth of S. commune fungus about 98.57% at a concentration of 2.5% with liquid smoke pyrolysis temperature used is 430°C.Keywords: efficacy, inhibition of fungal growth, liquid smoke, medang wood, Schizophyllum commun
Toposequent Effect on Soil Morphology and Classification of Ultisol Soil in the Ayer Hitam Forest Reserve, Peninsular Malaysia
Full text linkMorphology in forest soils has developed over a long time due to the non-intensive management of forest soils. Damage to forest soil occurs when there is logging activity, fire, or land use change. Some forest was used as productive land for example agroforestry and forest production. As with landuse in agriculture, intensive management of forests can also reduce soil productivity. Inaccuracy forest land use would cause environmental or economic damage, so basic soil management data in forest areas is needed. However, the soil morphology of the Ayer Hitam Forest Reserve (AHFR) in Malaysiahas never been observed. The objective of this study is to assess the soil characteristic and soil morphological properties of theAHFR. Studying the characteristics of soil morphology in toposequent conditions is necessary to find out the differences in soil from different heights and the effects of erosion, transportation, and deposition on the soil. This study was conducted in the AHFR, Puchong, Selangor Darul Ehsan, Peninsular Malaysia. Mapping of the area under investigation was carried out by conventional soil survey techniques with a physiographic approach using maps with a scale of 1:30,000. The results showed that AHFRhas some different soil morphological characteristics and classification in subgroupamong five different slope positions with similar soil order, which is a Ultisol soil. The soil in the AHFRis formed from highly weathered soil due to high rainfall in this location.The results of this study are important for soil development, identification management, and land use priority such as erosion control on steep-slope forest areas, regeneration and reforestation, and it can also be used for forest education, practice, research, and training activities.Keywords: Ayer Hitam Forest Reserve, forest soil, soil morphology, toposequent, Ultisol soi
Pengaruh Karakteristik Kimia terhadap Sifat Mekanis dan Keawetan Alami Tiga Jenis Kayu Kurang Digunakan (Effect of Chemical Characteristics on Mechanical and Natural Durability Properties of Three Lesser-Used Wood Species)
No full textChemical, mechanical, and natural durability properties of three lesser-used wood species from North Kalimantan, namely nyatoh (Palaquium lanceolatum), pisang putih (Mezzettia leptopoda), and sepetir (Sindora wallichii) woods,were analyzed to seek the interrelationships amongthem and give an overview related to their utilization. The results showed that pH values of three wood species were categorized into moderate to weak acid levels. The extractive contentsin hot and cold water as well as in NaOH 1% of sepetir wood were higher than those of nyatoh and pisang putih woods. In contrast, the solubility in ethanol-benzene of nyatoh wood was the highest. The ash content in the three wood species were categorized intomedium level. Lignin contents in sepetir and nyatoh woods were classified as moderate, while lignin content in pisang putih wood was high. Holocellulose and hemicellulose contentsin sepetir wood were higher than those in nyatoh and pisang putih woods, whereas alpha cellulose in sepetir wood was the lowest. MOE values of the three wood species were classified as strength class of IV‒V, while MOR and compression parallel to the grain were classified as strength class of IV. The hardness value of nyatoh wood was higher than that of other woods.The durability of the three wood species was classified into poor (low durable). The relationship between chemical characteristics and mechanical properties of wood was primarily influenced by its major components (cellulose, hemicellulose, and lignin), whereas natural durability was influenced by its minor components (extractives and inorganic materials).Keywords: lesser-used wood species, mechanical properties, natural durability, parameters interrelationship, wood chemical characteristic
Modal Sosial Masyarakat Pengelola Hutan Kemasyarakatan di Kesatuan Pengelolaan Hutan Batutegi (Social Capital of Community Forest Management in Batutegi Forest Management Unit)
Full text linkSocial capital has a role in the management of Community Forests (HKm) as a resource that could encourage individuals or groups to work together in achieving mutual goals. The objective of this study was to determine the social capital of the HKm management in the area of Batutegi Forest Management Unit, Tanggamus Regency, by farmers groups as Gapoktan Sinar Harapan and Gapoktan Mahardika. Data were collected in both farmers groups through structured interviews, unstructured interviews, observations, and literature review. The social capital of the community was analyzed qualitatively using social capital elements, such as trust, social networks, and social norms. The results showed that social capital has a positive role in managing HKm to encourage the community to manage the forest in sustainable manners. The results also showed that trust in a group creates social networks. Gapoktan Sinar Harapan implemented the three elements of social capital, such as trust, social networks, and social norms in their management. Gapoktan Mahardika only implemented trust and social norms, because the member of Gapoktan Mahardika was not only consisted of local people but also some immigrants. Hence, the implementation of social networks is needed in the management of HKm by Gapoktan Mahardika. Keywords: community forest, social capital, social networks, social norms,trus
Pengaruh Pematahan Masa Dormansi melalui Perendaman Air dengan Stratifikasi Suhu terhadap Perkecambahan Benih Aren (Arenga pinnata) (The Effect of Dormancy Breakdown through Water Immersion with Temperature Stratification on the Germination of Sugar Palm Seeds (Arenga pinnata))
Full text linkSugar palm (Arenga pinnata) has a hard and impermeable pericarp, which make an obstacle for it’s germination. Scarification of seed is needed to breakdown the physical dormancy of seeds. One of the methods to break the physical dormancy is stratification by soaking seed in to the water in some different temperature level. The aims of the study were to determine the effectiveness of stratification and to figure out the best water temperature in breaking the dormancy. A Completely Randomized Design (CRD) in four treatments (control, water immersion at 25°C, 50°C, and 75°C) with four replications was employed as research design. Statistical analysis was conducted using homogenity of variance, variance analysis, and least significant difference tests. The result showed that the water immersion of arenga seed at 25°C and 50°C resulted in the germination percentage, germination rate and test germination that was comparable to control. Water immersion at 75°C reduced the percentage of germination and germination rate, however the treatment could increase the germination test. Water immersion of arenga seed at 25°C, 50°C, and 75°C were not effective to break the dormancy of sugar palm seed.Keywords: aren seeds, dormancy, water immersio
