Abstract

Pooti (Hopea gregaria) is an endemic plant in Southeast Sulawesi that produces resin. But until now it has not been used because information about the quality of pooti resin has never been available. Therefore, this study aims to test the quality of pooti resin based on visual, acid number and ash content test. Pooti sap taken is on a tree with a diameter of 30 cm and a visual test is carried out based on SNI 2900-1-2012 and SNI 2900.2: 2013 for laboratory tests. The result is pooti resin with a clear yellowish color with a chunk size> 3x3 cm2, based on SNI 2900-1-2012 classified as Quality Class A. While the ash content value is 0.7% and the acid number is 29. This value indicates the ash content and acid number based on Laboratory tests are classified as quality class II based on SNI 2900.2: 2013.

Abstract

This study aims to determine the biomass and the amount of carbon found in Sengon stands (Falcataria moluccana)   community forest in the location of planting KBR (Kebun Bibit Rakyat) in Jati Bali Village, Ranomeeto Barat District, South Konawe Regency. This research was conducted from July to August 2018. The population in this study included a community forest of which was the location of planting KBR in 2014 with a plant age range of 5 years determined by purposive sampling. The sample in this study were all sengon stands (Falcataria moluccana) found in the observation plot determined using amethod completely randomized design (CRD).The results showed that the biomass found in Sengon stands (Falcataria moluccana) in community forests where the community nursery was planted in 2014, the amount of biomass based on the place of growing was wet enough, the place to grow wet and where to grow dry were 3,20 ton/ha, 0,60 ton/ha, and 1,68 ton/ha. While the amount of carbon in Sengon stands  (Falcataria moluccana) in community forests the location of community nursery plantations in 2014 was obtained at 1,50 ton/ha at the place of growing wet enough, 0,28 ton/ha at the place to grow wet and 0,79 ton/ha at the place of dry growth .

Abstract

Jati putih (G. arborea Roxb.) termasuk dalam kelas ketahanan tipe IV-V. Umur layanannya relatif singkat. Perlu dilakukan pengawetan untuk memperpanjang umur layanannya. Penelitian ini bertujuan untuk mengetahui daya tahan kayu jati putih (G. arborea) yang diawetkan dengan pengawet boraks dan terusi terhadap serangan rayap tanah (Coptotermes curvignathus). Penelitian ini dilaksanakan di Laboratorium Kehutanan Fakultas Kehutanan dan Ilmu Lingkungan Hidup dan Kebun Raya Universitas Halu Oleo pada bulan Desember 2020 sampai Maret 2021. Metode pengujian serangan rayap bawah tanah menggunakan metode grave selama 12 minggu. Ketahanan kayu dihitung dari persentase kehilangan berat dan tingkat serangan rayap tanah terhadap kayu. Hasil penelitian ini menunjukkan bahwa pengawet terusi memberikan hasil terbaik dengan konsentrasi 4% rata-rata persentase susut bobot 2,27%, sedangkan posisi di batang yang memberikan hasil terbaik adalah posisi pangkal dengan persentase. penurunan berat badan sebesar 1,61%. Daya tahan kayu jati putih terhadap serangan rayap tanah dari kedua bahan pengawet tersebut memberikan hasil yang baik, menurut SNI 01-7207-2006. Mengenai klasifikasi ketahanan kayu terhadap serangan rayap tanah yaitu konsentrasi 4% termasuk dalam kelas sangat tahan (I) sedangkan konsentrasi 2% termasuk dalam kelas tahan (II). Pada level serangan, kontrol mengalami serangan yang sangat berat. Sampel yang menggunakan boraks dan terusi dengan konsentrasi 4% menunjukkan tidak ada serangan, sampel boraks dan terusi dengan konsentrasi 2% menunjukkan sedikit serangan.

Abstract

The Kendari Bay mangrove ecosystem has an important role in maintaining the balance of coastal and marine ecosystems, especially as a natural protector from coastal erosion and seawater abrasion, as well as a habitat for various flora and fauna. However, these ecosystems continue to face pressure from human activities, such as deforestation for ponds, reclamation, and coastal development, which are exacerbated by climate change. This community service aims to increase awareness of mangrove sustainability in Kendari Bay, by involving religious extension workers and youth organizations. This activity included socialization about the importance of mangrove conservation and the planting of 300 mangrove seedlings in the area. Religious extension workers, as pioneers in the community, have an important role in spreading a culture of caring for the environment. Similarly, youth organizations act as agents of change that promote the values of environmental care among members and the wider community. Through the collaboration between Halu Oleo University, the Regional Office of the Ministry of Religious Affairs of Southeast Sulawesi, and the Ansor Youth Movement, this program is expected to be able to create conservation cadres and build a culture of caring for the environment. This effort not only focuses on mangrove planting, but also integrates religious and youth values in conservation practices. Thus, this program contributes to the preservation of sustainable mangrove ecosystems in Kendari Bay

Abstract

The objective of this community service activity was to improve the understanding of fifth-grade students at SD 92 Kendari regarding the medicinal plant Melaleuca cajuputi through an ecotourism education programme at the Halu Oleo University Botanical Garden. The methods used included presenting material on the benefits of medicinal plants, particularly cajuput, as well as direct observation of cajuput trees in the botanical garden. The activity also involved explanations from the botanical garden managers regarding biodiversity and the importance of preserving medicinal plants. The results of this activity showed a significant increase in students' knowledge of the medical and ecological benefits of cajuput. Before the activity, most students only knew white wood as a mild medicinal product, but after participating in the activity, 85% of students demonstrated a deeper understanding of the medical benefits of white wood, including its antimicrobial, anti-inflammatory, and analgesic properties. Additionally, students developed an awareness of the importance of preserving medicinal plants and biodiversity. This eco-tourism-based educational activity proved effective in increasing students' interest in environmental conservation and introducing them to sustainability concepts. These findings underscore the importance of developing botanical gardens as educational centres that can support environmental conservation and the preservation of medicinal plants for a better future.
