Cuscus (Spilocuscus maculatus) in captivity that were given a dominant fruit diet needed additional feed from their natural habitat because of the higher nutritional potential and fiber components. This study aims to determine the palatability of cuscus to the feed based on organic value. An experimental method was used, consisting of 4 treatment groups: 100% banana (Musa paradisiaca) as control, 70% banana mixed with 30% matoa (Pometia pinnata) leaves, 70% banana mixed with 30% ironwood (Pongamia pinnata) leaves, and 70% banana mixed with 30% crickets (Gryllus bimaculatus). The results showed that banana was the most preferred feed ingredient, either alone or as a supplementary feed mixture. In terms of quantity, its mixture with matoa leaves had a higher consumption level than ironwood leaves and crickets. The consumption level of organic matter was higher in the treatment with 100% banana than in other treatments. This information will help support ex-situ and in-situ conservation programs formulated by the government and other parties, including the community.

The mangrove ecosystem faces significant challenges, as its quality and quantity are threatened with decline. This study aimed to analyze the mangrove density and macrobenthos diversity in the Ampekale Ecotourism Village, Indonesia. This research utilizes remote sensing image analysis through the Normalized Difference Vegetation Index (NDVI) method. Complementary ground-check surveys were conducted to ascertain the density and diversity of mangrove and macrobenthos species. The overall mangrove density in the Ampekale area was relatively high, with some areas displaying moderate density. The sequence of mangrove species, from most common to least common, includes Rhizophora mucronata, Avicennia marina, Avicennia alba, Rhizophora apiculata, Sonneratia alba, Bruguiera gymnorhiza, and Acanthus ilicifolius. The most prevalent macrobenthos belong to the Crustacea class, such as Uca sp., Sesarma, Metaplax sp., and Scylla serrata. Moreover, the most diverse macrobenthos belong to the Gastropods class. The distribution of this biodiversity depends on their location (coastal or inland), tidal fluctuations, and river estuaries. Mangrove ecosystems situated in estuaries with high densities exhibited elevated macrobenthos abundance. This correlation suggests that areas characterized by dense mangroves also harbor stable ecosystem conditions with abundant macrobenthos. In contrast, ecosystems featuring lower biodiversity demonstrated reduced stability. These findings contribute valuable insights into the conservation and sustainability of mangrove ecosystems.

Halu Oleo University (UHO) Botanical Garden is one of the green open spaces that contribute to maintaining climate stability and environmental comfort in Kendari City, along with the high land use change due to increased population and city progress. The study aimed to determine the effect of land cover types on microclimate in UHO Botanical Garden and its surroundings. The research was conducted from June 2021 to January 2022. The research was conducted on three types of vegetation land cover. The variables measured were microclimate, including light intensity, temperature, relative humidity, and temperature humidity index. Measurements were conducted in the morning, afternoon, and evening. The method used was descriptive quantitative and statistical analysis using the analysis of variance and the least significant difference (LSD) test. The results showed that the microclimatic conditions of UHO Botanical Garden in tree-dominant land cover are more comfortable and significantly different from grass-dominant and settlement-dominant, but they are not significantly different between grass-dominant and settlement-dominant. This fact indicates the importance of the conservation of tree vegetation and the need for supervision so that there is no diversion of functions into settlements to maintain the preservation and sustainability of UHO Botanical Garden as one of the green open spaces that control climate stability and environmental comfort in Kendari City.

Mangrove forests are important ecosystems. However, land conversion and degradation have destroyed a significant area of mangrove. Mangrove restoration employing native species has been performed in several degraded areas, including some North Sumatra regions. However, information regarding floristic diversity in monoculture restoration areas is still limited. This research aims to analyze the floristic diversity in the mangrove restoration area, which is dominated by Soneratia alba species in Pasar Rawa Village, North Sumatra. The plotted path approach was employed for vegetation analysis in a 3-ha area in Pasar Rawa. The findings revealed that 8 (eight) species were found in the S. alba restoration area. The highest Important Value Index (IVI) in the seedling stage was found in Acanthus ilicifolius, while at the sapling and tree stages, S. alba was the highest. The highest diversity index was obtained at the sapling stage, which was 1.46 (medium), and the lowest was obtained at the tree stages, which were 0.26 (low). The result showed a new recruitment of seedlings in the research location, although the species diversity value is still lower. The appearance of new species, particularly pioneer species, in the research area indicates that natural succession processes are currently taking place.

红树林是重要的生态系统。然而，土地转换和退化破坏了大片红树林。在一些退化地区，包括北苏门答腊的一些地区，已经采用本地物种恢复红树林。然而，有关单一栽培恢复区植物多样性的信息仍然有限。本研究旨在分析北苏门答腊 Pasar Rawa 村以 Soneratia alba 树种为主的红树林恢复区的植物多样性。在 Pasar Rawa 面积为 3 公顷的区域内采用了绘制路径法进行植被分析。研究结果表明，在白叶松恢复区发现了 8 个物种。在幼苗阶段，重要价值指数（IVI）最高的是刺桐（Acanthus ilicifolius），而在树苗和树木阶段，白眉刺桐的重要价值指数最高。树苗阶段的多样性指数最高，为 1.46（中），树龄阶段的多样性指数最低，为 0.26（低）。结果表明，虽然物种多样性值仍然较低，但研究地点出现了新的树苗。研究区出现的新物种，尤其是先锋物种，表明目前正在进行自然演替过程。 关键词：植物学；红树林；单一物种；恢复；白桑树

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. Keywords: bamboo, methylene diphenyl diisocyanate, natural weathering, oriented strand board, steam treatment
这项研究的目的是检验用天麻竹丝制成的竹材定向刨花板（BOSB）在经过和未经蒸汽处理的情况下的质量。此外，还研究了自然风化暴露时间的长短对定向竹刨花板物理和机械特性的影响。蒸汽处理持续一小时，温度为 126°C，压力为 0.14 兆帕。二苯基二异氰酸甲酯（MDI）和石蜡被用作粘合剂和添加剂，浓度分别为 5%和 1%（基于烘干重量）。BOSB 在印度尼西亚西爪哇 Bukit Bogor Raya Pajajaran 遭受了不同时间（0、1 和 3 个月）的自然风化。随后，对 BOSB 的物理和机械性能以及保留价值进行了测试。结果表明，与未经处理的 BOSB 相比，蒸汽处理能更好地改善用 MDI 粘合剂粘合的 BOSB 的尺寸稳定性和机械性能。然而，与未经处理的样品相比，蒸汽处理对自然降解的保护水平更高。这证实了经蒸汽处理的定向刨花板是一种耐用且可持续的建筑材料。 关键词：竹材；亚甲基二苯基二异氰酸酯；自然风化；定向刨花板；蒸汽处理
