Abstract

Development of cajuput plantation currently becomes the most important activity in KPH Bojonegoro since it provides an essential contribution to maintain the future viability of company. However,the growth performance of cajuput stand relatively varies one of which is influenced by planting design. This study aims to determine the optimum planting design for supporting cajuput stand development. It was conducted by evaluating two different planting designs that generally used for cajuput establishment, namely C1 (spacing 3 m x 1 m) and C2 (spacing 5 m x 1.5 m x 1.5 m). Five parameters were used to evaluate the growth performance and oil production of cajuput stand for each planting design, i.e., survival rate, quadratic mean diameter, basal area, harvesting biomass, and cajuput oil production. Data were collected by field measurementusing a sampling plot 50 m x 50 m with six replications for each planting design. Comparisonmean of cajuput growth performance between two planting designs were analyzed separately for each parameterusing t-test. Results documented there were not a significant different for all parameters, except survival rate. The planting design C2 generated higher survival rate (94.9%) than planting design C1 (64.7%).The planting design C2 was recommended for cajuput development in KPH Bojonegoro. Besides requiring the lower planting density, the use of planting design C2 can optimize land utility with a similar productivity to planting design C1.

Abstract

Forest rehabilitation of Timor Island's dryland ecosystems using eucalyptus plants plays an important role in improving land cover but also in mitigating climate change and providing an alternative renewable energy source. The aim of this study is to explore the enormous energy storage potential of eucalyptus plants for commercial purposes using a high spatial resolution remote sensing approach. The Pléiades satellite imagery acquired on 10/09/2021 covering ca. 27 ha study area managed by Timor Tengah Selatan Forest Management Unit was used to identify the density of eucalyptus plants using Normalized Difference Vegetation Index (NDVI) values greater than 0.699. The density of eucalyptus plants is classified into low, moderate, and high tree density with NDVI values greater than 0.699 to 0.765, greater than 0.765 to 0.833, and greater than 0.833 to 0.901, respectively. The total potential energy production of the study area was estimated using a combination of assumed eucalyptus tree density, the calculated area of each density, and the average energy storage of individual trees. The results showed that the density of eucalyptus trees was classified as low, moderate, and high, with coverage areas of 6.8 ha, 12.9 ha, and 3.0 ha, respectively. The potential energy production of low, moderate, and high density approaches 1,103,432.33 MJ; 5,522,999.19 MJ; and 2,120,715.04 MJ, respectively, with a total estimated energy storage of 8,747,146.57 MJ. This obtained number of potential energy estimations indicates that forest rehabilitation of dryland ecosystems through eucalyptus plantations has a promising future as an alternative renewable energy source.

Abstract

Community-based tourism has become an alternative sustainable development strategy that enhances local livelihoods while promoting forest conservation, especially in areas where resource use is limited. This study used a five-dimensional framework, including ecological, economic, social, nature tourism services, and institutional dimensions, to assess the sustainability status of the Jurang Jero Nature Tourism Object’s management. Field observations and respondent interviews were used to gather primary data, which was then analyzed using a rapid appraisal technique for fisheries (Rapfish) modified for Rap-tourism. The results show that management of the Jurang Jero Nature Tourism Object is moderately sustainable, reflecting balanced performance across ecological, economic, social, institutional, and nature tourism service dimensions. Even though the ecological and social dimensions are comparatively strong, more advancements in nature tourism and economic dimensions are required. Improving sustainability and promoting advancement require increased cooperation between stakeholders. Recommended strategies include strengthening human resource capacity through targeted training, developing environmentally sustainable tourism infrastructure, and improving the quality of tourism services and attractions through corporate social responsibility initiatives.
