Abstract

Kuala Tolam Village, Pelalawan Regency, Riau Province, is one of the regions that still possesses significant peatland forests, which are ecologically, socially, and economically important. However, pressures from plantation expansion, land conversion, and limited community knowledge about forest functions have made this area vulnerable to degradation. This community service activity aimed to enhance public knowledge of the importance of forests. The method employed was socialization through an educational, participatory, and interactive approach combined with small group discussions. The respondents in this activity were stakeholders involved in community deliberations with the Siak Pelalawan Landscape Program in the context of forming a collective commitment to maintain forest functions and areas. The results of this activity showed an increase in community knowledge about forest functions as measured by several aspects, namely forest definition, forest types, and forest functions. Community understanding of the definition of forests increased by 39%, knowledge of forest types around Kuala Tolam Village increased by 36%, and knowledge of forest functions increased by 30%. These findings indicate that the socialization and educational approaches applied were successful in raising public awareness of the importance of forests in supporting the community’s commitment to preserving forest functions and areas. Furthermore, the formation of such commitment, supported by enhanced knowledge and understanding, is expected to serve as a strong foundation for establishing a forest patrol and monitoring team in Kuala Tolam Village, Pelalawan Regency.

Abstract

Salah satu vegetasi yang dijadikan sebagai alternatif dalam revegetasi lahan adalah anaman Trembesi (Samanea saman). Tumbuhan trembesi dapat tumbuh dengan baik jika diberikan unsur hara yang baik yaitu dengan campuran tanah dengan bahan orgnaik. Bahan organik yang berpotensi untuk perbaikan sifat fisik tanah adalah serbuk gergaji. Tujuan penelitian ini dilakukan untuk mengetahui pengaruh pemberian kompos serbuk gergaji gaharu sebagai media tanam dan untuk mengetahui komposisi optimal media tanam kompos serbuk gergaji gaharu terhadap pertumbuhan semai trembesi. Metode pengamatan ini dilakukan dengan memperhatikan persentase hidup, pertambahan tinggi semai dan diameter batang, nilai kekokohan, berat kering total, nisbah pucuk akar dan indeks mutu bibit. Data yang didapatkan kemudian dianalisis sidik ragam secara statistik menggunakan software SPSS versi 17.0. Kesimpulan dalam penelitian ini yaitu bahwa pemberian kompos serbuk gergaji gaharu berpengaruh terhadap persentase hidup, tinggi, diameter, dan kekokohan semai terhadap semai trembesi dan Komposisi optimal kompos serbuk gergaji gaharu terhadap pertumbuhan semai trembesi yaitu perlakuan P3 dimana rata-rata persentase hidup 60%, pertambahan tinggi 2,98 cm, pertambahan diameter 1,13 mm, nilai kekokohan semai 8,46, nisbah pucuk akar 1,56, dan indekd mutu bibit 1,86.
