Abstract

Informasi mengenai keanekaragaman dan pemanfaatan etnobotani bambu di Kecamatan Lampasio, Kabupaten Tolitoli, masih terbatas, meskipun wilayah ini memiliki potensi sumber daya bambu yang tinggi dengan sebaran relatif merata di hampir semua desa. Penelitian ini bertujuan menganalisis jenis-jenis bambu dan bentuk pemanfaatannya oleh masyarakat. Penelitian dilakukan pada Februari–April 2025 menggunakan metode jelajah untuk eksplorasi jenis, serta studi etnobotani dengan purposive sampling dan snowball sampling. Nilai kepentingan budaya setiap jenis dianalisis dengan Index of Cultural Significance (ICS). Hasil penelitian menemukan sembilan jenis bambu yaitu Bambusa vulgaris var. striata (Lodd.ex Lindl), Bambusa vulgaris var. vulgaris Schard, Schizostachyum brachycladum Kurz, Dendrocalamus strictus (Roxb). Nees, Gigantochloa pseudoarundinacea (Steud.) Widjaja, Gigantochloa atroviolacea Widjaja, Schizostachyum lima (Blanco) Merr, Bambusa glaucophylla Widjaja, dan Bambusa multiplex (Lour.) Jenis bambu dengan nilai ICS tertinggi adalah Schizostachyum brachycladum Kurz (ICS = 516), yang dimanfaatkan luas sebagai bahan pangan, pagar, kayu bakar, wadah nasi lemang, tali, dan anyaman. Jenis ini perlu difokuskan pada konservasi dan budidaya untuk menjaga ketersediaannya. Sebaliknya, Bambusa glaucophylla Widjaja dan Bambusa multiplex (Lour.) memiliki nilai ICS terendah (ICS = 12), mencerminkan pemanfaatan yang terbatas. Kedepan, kedua jenis ini berpotensi dikembangkan melalui eksplorasi pemanfaatan baru dan peningkatan kesadaran masyarakat terhadap nilai tambahnya.

Abstract

Customary forests play a crucial role in maintaining ecosystem balance, biodiversity, and the sociocultural sustainability of local communities. However, pressure on forest cover continues to increase due to land clearing and conversion. This study was conducted from February to July 2025 in the Ngata Toro Customary Forest, Toro Village, Kulawi District, Sigi Regency, to analyze land cover changes from 2021 to 2025 using satellite imagery and the Object-Based Image Analysis (OBIA) segmentation method. The results show a decrease in forest area from 1,604.16 ha (2021) to 1,475.98 ha (2025), or a decrease of approximately 128.18 ha (7.99%), accompanied by an increase in non-forest area from 140.99 ha to 268.88 ha. Initial changes occurred in high-access areas near settlements and roads, then spread inland, leading to forest fragmentation. Peak deforestation occurred in 2024, with a decrease of 57.49 ha in one year. Spatial patterns show a close relationship between deforestation and accessibility, topography, and agricultural intensification. Classification accuracy tests yielded an overall accuracy of 80–85%, with the highest in 2021 and the lowest in 2023. Fragmentation reduces habitat connectivity, threatens wide-ranging species, and degrades ecosystem functions such as carbon storage and hydrological regulation. These results underscore the importance of ecosystem-based management strategies and controlled land clearing to maintain the ecological integrity of customary forests.

Abstract

The soil physical and chemical properties and fertility under the natural stands of ebony were investigated from October 2022 to June 2024. The locations are the Gunung Sojol Nature Reserve and the Forest Management Unit of Sintuwu Maroso, Sulawesi. Ebony is dominant at all growth levels in Sintuwu Maroso, but only at pole level in Sintuwu Maroso as indicated by the IVI. The basal area and volume in Sintuwu Maroso are higher, indicating higher potential than Gunung Sojol. The medium texture soil with optimal moisture in Sintuwu Maroso also supports better growth than the coarse soil in Gunung Sojol. The soil in Gunung Sojol is characterized by acidic pH and high level of organic C, total P, total K, and Al-dd. Meanwhile, the soil in Sintuwu Maroso is slightly acidic with moderate levels of previous parameters. Despite high organic matter and CEC, the soil fertility of Gunung Sojol is hampered by low acidity and base saturation. While Sintuwu Maroso is challenged by low nutrient and organic matters. In general, both locations have moderate soil fertility. The results can serve as a basis for effective cultivation and conservation strategies for both in-situ and ex-situ methods
