Abstract

The Andong Merah plant (Cordyline fruticosa) is known to have natural antibacterial properties, which can inhibit the growth of cancer and tumors. Several studies that have been carried out previously showed the potential of red Andong Merah plant extracts for health, especially in the Andong Merah leaves with many active compounds. This study explored the potential of Andong Merah leaves for their phytochemical analysis, antioxidant and antibacterial activity. Andong Merah leaves were macerated using n-hexane, ethyl acetate, and ethanol solvent to yield the crude extracts. The phytochemical analysis was evaluated by the Harborne and Kokate method. Antioxidant activity was evaluated by DPPH radical scavenging assay. Antibacterial activity was examined using the agar well diffusion method against Propionibacterium acnes, Streptococcus mutans, and Streptococcus sobrinus. The results showed that the Andong Merah leaves extract contains alkaloids, flavonoids, tannins, steroids, and saponins. The antioxidant activity test showed that the n-hexane and ethyl acetate of Andong Merah leaves extracts displayed the ability to inhibit DPPH free radical by 74% and 75% at 200 ppm concentration, while ethanol extracts by 79% at 100 ppm concentration. The antibacterial activity showed that the ethanol extract of Andong Merah leaves displayed the ability to inhibit the Propionibacterium acnes growth with 12 mm inhibition activity at 400 µg. The ethanol and ethyl acetate of Andong Merah leaves extract can inhibit the Streptococcus mutans growth with 9 mm at 400 µg. Antibacterial activity of n-hexane, ethyl acetate, and ethanol extract of Andong Merah leaves display the ability to inhibit the Streptococcus sobrinus growth with 10 mm at 400 µg concentration. Based on the results, Andong Merah leaves (Cordyline fruticosa) display potential as a natural antioxidant and antibacterial agent.

Abstract

Kayupuring village has a dense forest which also the habitat for Javan Gibbon. Coffee plants is also present in the forest and utilised by the local community for their livelihood. Therefore, forest protection and utilisation activities need to be aligned to ensure sustainability. Swara Owa is one of the stakeholders conducting that approach through a program of Coffee and Primates Conservation Project. This study aims to overview the future sustainability of the program. System thinking is employed, and data were obtained through desk study and literature review with the scope of 2013-2019. Four main variables selected to describe the system are forest degradation (ecosystem), coffee price (wellbeing), local institutional strength – Village Forest Community Institution/LMDH (social), and forest conservation awareness (cultural paradigm). The interaction of the program system can be explained that the higher the conservation awareness level, the higher the forest quality, then the stronger LMDH, the higher coffee price; and the higher coffee price makes conservation awareness high. The higher coffee price, the people are more aware to conservation issue because the coffee comes from an area of the wildlife habitat. The three main strategies to achieve ideal vision are tenure mapping, policy intervention, and community participation and empowerment.

Abstract

Increased attention to the environment causes the need for alternative preservatives to replace synthetic preservatives. Using plant extracts containing antifungal compounds can be an alternative to reducing the use of wood preservative chemicals. This study aimed to analyze the efficacy of the bark of Lannea coromandelica against the rot fungus Auricularia auricula-judge and to obtain an adequate concentration of preservative which can later be used as a natural preservative in wood from community forests. The method used in this research is divided into three stages. The first stage begins with the process of preparing raw materials. The second stage is to carry out the process of extracting the bark of Java. The last stage of this research is to test the effectiveness of antifungals in Java bark extract. Java bark extract was tested at various concentrations, namely 5 ppm, 10 ppm, 15 ppm, 20 ppm, and 25 ppm, and the control without extract. Each treatment was repeated five times. This study showed that Java bark extract at concentrations of 5 ppm, 10 ppm, 15 ppm, 20 ppm, and 25 ppm could inhibit the growth of the fungus Auricularia auricula-judge. It was indicated by the absence of hyphae that grew after 16 days of observation.

Abstract

This research aims to analyze the effect of paint viscosity on the adhesion of the final coating material to the radial and tangential sections of Rajumas wood. The research samples were smoothed using sandpaper and coated with water-based paint. Variations in paint viscosity are obtained by dilution using 10%, 20% and 30% of 1L of water. The viscosity of the paint solution obtained by dilution of 10%, 20% and 30% was 2.32 poise, 2.41 poise and 2.44 poise, respectively. Paint adhesion testing uses the Cross Cut Test method which refers to ASTM D 3359-09. The results of the research show that variations in paint viscosity have a significant effect on the adhesion of the final coating material to the radial and tangential cross-sections of Rajumas wood. A viscosity of 2.32 poise produces the best paint adhesion compared to a viscosity of 2.41 poise and 2.44 poise and the difference in cross-section (radial and tangential) does not show a significant difference in the adhesion value of the final coating material to Rajumas wood.

Abstract

Rajumas wood is one of the local wood forest products from West Nusa Tenggara and has low strength and durability. Finishing treatment is needed for the service life of wood. One of the indicators of finishing quality is the ability of paint liquid wetting on the wood surface (wettability). This research aims to analyze the effect of paint viscosity on the wettability of rajumas wood. The samples used were radial and tangential sections in air-dry condition, and the wood surfaces were sanded with abrasive paper of 150 grit. The value of viscosities was 2.44, 2.41, and 2.32 poise from each percentage of paint and water ratio of 90%:10%, 80%:20%, and 70%:30%. Wettability was determined based on the rate of change equilibrium contact angle using the S/G equation. The research results show that the low viscosity value of Aqua Politur produces the lowest equilibrium value and highest wettability value (K-Value) in both radial and tangential sections. A high K-value indicates that Aqua Politur's ability to wet the wood surface is better, as shown by the paint percentage ratio of 70%:30%.
