Abstract

Coptotermes curvignathus is a termite pest that attacks buildings, plantations, and forests. Controlling this pest requires environmentally friendly natural materials. The bintaro plant (Cerbera odollam) are known in Indonesia as natural insecticides and traditional medicines because of their strong toxic properties, so they have the potential to be used in termite control. This study evaluated the efficacy of C. odollam leaf and fruit peel extracts as natural termiticides and their effectiveness against subterranean termite C. curvignathus. The extraction process used three solvents with different polarities: n-hexane, acetone, and ethanol. Anti-termite bioactivity tests were conducted following the Japanese Industrial Standard (JIS) 1571-2010 method. Ethanol extract from C. odollam leaves produced the highest yield (9.52%). Phytochemical analysis showed the presence of alkaloids, flavonoids, phenolics, steroids, and saponins in both leaf and fruit peel extracts. The anti-termite bioactivity test showed that the leaf extract with acetone solvent caused 97.33% mortality, while the fruit peel extract with ethanol solvent caused 100% mortality at a 5% concentration. This study demonstrates that C. odollam leaf and fruit peel extracts have strong potential as natural termiticides.

Abstract

Wood vinegar, scientifically defined as the condensation product of thermal decomposition (pyrolysis) of biomass rich in cellulose, hemicellulose, and lignin, presents a critical strategic step in efficient biomass waste management in Indonesia. Raw materials like coconut shells and palm oil waste are abundant, making their market potential highly promising. However, Indonesian Small and Medium Enterprises (SMEs) predominantly produce Grade 3 wood vinegar, which contains high levels of carcinogenic tar, hindering access to premium food-grade and pharmaceutical markets. This review aims to present a comprehensive report on the scientific characteristics and quality classification of wood vinegar, specifically analyzing the mechanism of action, effectiveness, and potential use of Grade 3 as an anti-termite agent (termiticide) and wood preservative, alongside its other advanced applications, such as food preservation, agricultural biopesticide, and latex coagulant. The method employed is a literature review, synthesizing data on chemical composition, purification standards (SNI and BPOM), and experimental findings on its multi-functional properties. The main conclusion is that Grade 3 wood vinegar proves highly effective as a termiticide, providing total wood protection and offering a safe, sustainable alternative to chemical wood preservatives. For food applications, rigorous purification to Grade 1 is essential to replace harmful practices like using formalin or borax. The novelty of this study lies in its integrated analysis of the technical efficacy (Grade 3 in termiticide) and the regulatory/commercial trade-off with food safety requirements (Grade 1), culminating in strategic recommendations for developing downstream purification technology for Indonesian SMEs
