Abstract

This study aimed to examine the qualities of bamboo-oriented strand board (BOSB) made from Dendrocalamus asper bamboo strands, both with and without steam treatment. Furthermore, the effect of exposure length to natural weathering on the physical and mechanical characteristics of BOSB was examined. The steam treatment lasted one hour at 126°C and a pressure of 0.14 MPa. Methylene diphenyl diisocyanate (MDI) and paraffin were utilized as adhesives and additives, with concentrations of 5% and 1%, respectively, based on oven-dried weight. The BOSB was exposed to natural weathering in different exposure durations (0, 1, and 3 months) in Bukit Bogor Raya Pajajaran, West Java, Indonesia. Subsequently, the BOSB was tested for its physical and mechanical properties and retention value. The result showed that steam treatment improved the dimensional stability and mechanical properties of BOSB bonded with MDI adhesive more than untreated BOSB. However, steam treatment has a better protection level against natural degradation than untreated samples. These confirm that BOSB with steam treatment is a durable and sustainable construction material.

Abstract

Indonesia known for its high biodiversity, is home to various species of wildlife, with 17% of the world's wild animals found in its territory. However, this wealth makes Indonesia one of the major suppliers of both legal and illegal wildlife trade, which threatens conservation efforts. This study aims to identify the potential of wildlife trade, health factors, and the welfare of traded animals. Conducted in Bandar Lampung in February 2022, the research employed direct observation through structured interviews with pet shop owners, as well as document studies. The findings indicate that despite a post-pandemic decline, wildlife trade in the region still holds significant potential. Health factors, such as mouth ulcers in pythons and metabolic diseases in geckos, pose major challenges, although adequate care is provided in these shops. Animal welfare remains a critical concern, as dependence on wild-caught animals from the wild threatens their sustainability. This study emphasizes the importance of implementing sustainable management practices and adhering to existing regulations to ensure the continuity of wildlife trade in Indonesia
