Abstract

The Way Belerang Simpur Bath in Kalianda, South Lampung, is a protected forest and village forest rich in tropical vegetation, including timber and non-timber trees. However, with the development of tourism, it puts pressure on the tree vegetation around the location on tree growth. This study aims to determine the value of tree productivity parameters (indicators) and obtain the final value around the tourist location of the simpur eagle bath, Kalianda, South Lampung as one of the indicators of forest health assessment. The method used is the creation of FHM plot clusters which results in the determination of 4 plot around the Way Belerang Simpur Bath Tourist Location. Analysis of tree productivity parameter data (indicators) using the LBD formula (Base Field Area) = 1/4 πd². The forest health assessment is obtained from the final value of forest health conditions formulated by NKH (Forest Health Value) = NT (Weighted Value) x NS (Score Value). The results showed that the values of tree productivity parameters (indicators) for each plot cluster were 85.109 m² (cluster 1), 81.455 m² (cluster 2), 128.569 m² (cluster 3), and 12.879 m² (cluster 4) each. The final value of tree productivity is 1.00 – 1.85 in the medium category. The final tree productivity score for forest health reflects that forest areas have not been managed optimally, so tree planting is needed to maintain tree growth. Thus, the value of tree productivity parameters (indicators) is 77.003. The final value of the average tree productivity is 1.60 with medium category status.

Abstract

This study evaluates the anatomical characteristics and basic mechanical behaviour of kenaf (Hibiscus cannabinus L.) core with the objective of assessing its suitability as a raw material for oriented strand board (OSB). Anatomical observations (cross, radial and tangential sections) revealed three distinct stem components (bast, core, pith) and showed variation in fibre and vessel element lengths along the stem (top, middle, bottom). Compression testing perpendicular to the grain provided baseline mechanical data relevant to strand production and panel performance. Based on anatomical features and compression response, kenaf core is proposed as a viable alternative biomass feedstock for wood-based composites such as OSB, particularly for short-rotation and urban biomass sources. The work demonstrates promise but highlights the need for further quantitative processing and full-scale panel manufacture/testing (modulus of rupture, modulus of elasticity, internal bond, dimensional stability) to confirm industrial feasibility.
