Abstract

Indonesia faces increasing pressure on its natural forest resources due to deforestation and rising demand for wood, encouraging the utilization of fast-growing species such as sengon (Falcataria moluccana) and underutilized invasive species such as African tulip (Spathodea campanulata). However, both species are characterized by naturally light surface colors, which are often perceived as less attractive for decorative and interior applications. Oil heat treatment (OHT) has been used to modify wood color and enhance visual appearance. This study evaluated the effects of OHT at 160°C, 180°C, 200°C, and 220°C for 2 hours on color changes and public color preferences of sengon and African tulip woods. Color changes were visually observed and quantitatively analyzed using the CIE-LAB color system, while preference data were collected through an online survey involving male and female respondents. The results showed that OHT caused significant darkening of wood surfaces, with African tulipwood exhibiting greater color changes than sengon. Preference analysis indicated that female respondents tended to favor wood colors heat-treated at moderate temperatures (180°C), whereas male respondents preferred darker colors produced at higher temperatures (200–220°C). For African tulip wood, treatment at 200°C was the most preferred overall by both genders. These findings demonstrate that oil heat treatment effectively modifies wood color and that consumer color preferences vary by gender, which may be considered in visually oriented wood applications.

Abstract

Purpose: This community service program aimed to explore the feasibility and benefits of utilizing corn cob waste for biochar production as a sustainable practice that can serve as a solution to address the issues of corn biomass waste, while simultaneously enhancing waste management, improving soil fertility, and stimulating local economic development. Methodology/approach: This community service program involved 27 farmers in Bangun Sari Village, Pesawaran, focusing on biochar benefits for soil improvement. The methodology included technical training on building biochar production facilities from corn biomass using clay kilns, production process training, establishing a biochar production unit, and providing ongoing support for production, packaging, and marketing of biochar. Results/findings: The community service program has significantly improved farmer’s knowledge on the agricultural waste utilization to support sustainable farming in Bangun Sari Village. The community service activity reveals that the application of biochar production technology using clay kiln techniques is easily adoptable by the community and involves relatively low production costs. Conclusion: By focusing on biochar production units, process training, and business development, the program will benefits local farmers and the community. Its success hinges on effective technical implementation and strong community and government support. Continued commitment and collaboration promise long-term positive impacts on environmentally friendly agriculture.
