Abstract

Kuala Tolam Village, Pelalawan Regency, has forest areas and peatland ecosystems that play an important role ecologically, economically, and socially for the community. However, these areas have been experiencing continuous decline and pressure due to industrial activities and land-clearing practices. This condition requires a deeper understanding of stakeholder perceptions of forest functions, as an essential basis for building a commitment to preserve and maintain the remaining forest areas. The purpose of this study is to analyze stakeholder perceptions of forest functions in efforts to maintain forest areas in Kuala Tolam Village, focusing on three aspects: economic, social, and ecological. The research employed both quantitative and qualitative approaches, using interviews with stakeholders who were involved in discussion forums for the formation of commitments to protect forest areas in Kuala Tolam Village. The results show that stakeholder perceptions of forest functions in Kuala Tolam Village fall into the “agree” category across all measured aspects economic, ecological, and social. The positive perceptions of stakeholders regarding forest functions indicate a collective awareness of the importance of forests for life. This awareness serves as social capital for building a shared commitment to safeguarding forest functions and areas.

Abstract

Swietenia mahagoni can grow on marginal land and is suitable for use as a revegetation plant. Peat is classified as marginal soil due to its high organic acid content and low levels of macronutrients. One approach to improving the productivity of peat soil is the application of ameliorants, one of which is oil palm boiler ash. This study aimed to evaluate the effect of mixing peat with oil palm boiler ash and to determine the optimal composition of this mixture for the growth of mahogany seedlings. A completely randomized design (CRD) was employed, consisting of five treatments with four replications, resulting in a total of 20 experimental units. The planting media compositions tested were: P0 = 100% peat soil (control), P1 = 10% boiler ash + 90% peat soil, P2 = 15% boiler ash + 85% peat soil, P3 = 20% oil palm boiler ash + 80% peat soil, and P4 = 25% oil palm boiler ash + 75% peat soil. Data were analyzed using SPSS version 26.0. The application of oil palm boiler ash had a significant effect on the growth of mahogany seedlings. The optimal composition was 15% boiler ash and 85% peat, which resulted in an average seedling height increase of 10.01 cm and an average dry weight of 6.61 g.

Abstract

This community service activity aimed to enhance the competencies of Forestry students at SMK Negeri 1 Tualang, Siak Regency, in drone-based videography using Unmanned Aerial Vehicle (UAV) technology. The training was conducted through an experiential learning approach that integrated theoretical instruction, technical demonstrations, and hands-on field practice. Training materials covered UAV fundamentals, flight safety, and aerial videography techniques relevant to forestry applications. The effectiveness of the program was evaluated using pre-test and post-test methods, supported by observations and interviews. The results indicated a substantial increase in the participants’ average scores, from 57.91% before the training to 96.51% after the training. The Wilcoxon Signed Rank Test revealed a statistically significant difference between pre-test and post-test results (p 0.05), confirming the positive impact of the training on students’ knowledge and technical skills. In addition, the program fostered improved confidence, discipline, and responsibility in drone operation. This activity contributes to strengthening vocational competencies and technological literacy in forestry education.
