“…By doing recalculation in accordance with the interim planning that [3] has conducted, agroforestry land will develop Jabon crops in an area of ± 5454 ha. Jabon plant is a plant with a planting age of seven years which is predicted to have an average height of 12.5 m and a diameter of 25 cm [4]. Assuming the yield of Jabon planting after the seventh year can be harvested every year, 5454 ha of land is divided into seven blocks with an area of 779 ha each.…”

This open-pit mining activity has a very helpful environmental potential, soil chemistry, erosion and sedimentation. Change in land use from mining actively after mining requires land and energy closure to ensure that the land is safe for and returned. In accordance with the local spatial pattern in Muara Enim, South Sumatra, the transfer of post-mining land after the dismissal of mining operations will be used as a conservation area managed by the mining community. The concept is an environmental addressing plan to determine the sustainability of various aspects of community life, including local sustainability, food environment, awareness, biodiversity, and sustainability. This study aims to ensure community sustainability after mining operations. The methodology that is an interview with Experts. The results of this research indicate that community empowerment in mining area can use one of the community's natural resource management strategies to ensure social sustainability with land use as agroforestry and integrated agricultural industries.

The productivity of cajuput plantation has improved through tree breeding, while manipulation of site and management engineering of timber plantations have been less attention. Management engineering can be obtained by determining the optimum cycle of cajuput leaves harvesting. This study aims to determine the optimum cycling of cajuput leaves harvesting at KPH Yogyakarta by considering the biological cycles of cajuput leaves, chemical physical properties, and the yield of cajuput oil. The tools used in the research were digital scales, distillation devices, and testing tools of physical-chemical properties of cajuput oil. The material for research was the cajuput plants at KPH Yogyakarta. Data of cajuput leave-twig biomass were obtained for 9 months from 9 plots which were well distributed on various ages. Biological cycle analysis uses curent monthly increment (CMI) and mean monthly increment (MMI) intersection approach. Analysis of the physical-chemical properties on cajuput oil refers to SNI 3954:2014 on cajuput oil. The results showed that the biological cycles of cajuput leaves were obtained 5 months after leaves harvesting. The chemical physical properties of cajuput oil that meet the requirements of SNI were achieved after the leaves are 7 months after harvested. The yield of cajuput oil which is above 0.7% was obtained after the leaves are 8 months after harvested. Thus, the optimum cycle for harvesting of cajuput leaves in KPH Yogyakarta is after 8 months.

Abstract. Cajuput (Melaleuca leucadendra L.) oil is one of potential commodity that provides an important role for the country's foreign exchange but the extraction of these essential oil is still using conventional method such as hydrodistillation which takes a long time to produce essential oil with good quality. Therefore it is necessary to optimize the extraction process using a more effective and efficient method. So in this study the extraction is done using solvent-free microwave extraction method that are considered more effective and efficient than conventional methods. The optimum yield in the extraction of cajuput oil using solvent-free microwave extraction method is 1.0674%. The optimum yield is obtained on the feed to distiller (F/D) ratio of 0.12 g/mL with microwave power of 400 W. In the extraction of cajuput oil using solvent-free microwave extraction method is performed first-order and second-order kinetics modelling. Based on kinetics modelling that has been done, it can be said that the second-order kinetic model (R 2 = 0.9901) can be better represent experimental results of extraction of cajuput oil that using solvent-free microwave extraction method when compared with the first-order kinetic model (R 2 = 0.9854).
