The use of conventional solvents in the oil paint industry often leads to volatile organic compound (VOC) emissions and toxicity, so this study aims to evaluate the potential of Fatty Acid Methyl Ester (FAME) as an environmentally friendly alternative solvent. FAME is synthesised from vegetable oil through a transesterification reaction, then formulated into alkyd resin-based paints with varying binder content (40%, 50%, and 60%) to be compared with acetone solvent. The paint performance evaluation includes tests on drying time, gloss level, hiding power, and Whiteness and Yellowness Index. The results show that FAME-based paints have a much higher gloss level (10–26 GU) than acetone (3–6 GU) because their slower evaporation rate provides optimal levelling time, though this results in much longer drying time, namely 780–819 minutes. In addition, FAME has been proven to produce better covering power and a lower Yellowness Index (1.39–4.15) than acetone (4.09–5.74). This superiority is influenced by the nature of FAME, which minimises damage to the polymer binder and uniformly disperses pigments, preventing agglomeration. Overall, FAME has great potential as a sustainable paint solvent that can improve optical and physical properties, although its formulation still requires optimisation to accelerate drying.

This community service activity aims to utilize eggshell waste from household businesses as raw material for Liquid Organic Fertilizer (POC) to support sustainable agriculture in Siak Regency. The main problems faced by partners are high dependence on inorganic fertilizers, rising production costs, and suboptimal utilization of local organic waste. The activity was carried out through the stages of POC production, counseling, demonstrations, discussions, and product distribution to farmer groups. The POC formulation was made from eggshells, water, molasses, and EM4, then fermented for seven days. The results showed that the POC product had good physical characteristics, with changes in pH indicating optimal fermentation. The counseling and hands-on practice also increased farmers' knowledge and skills in processing eggshell waste into fertilizer that can be used independently. This program has the potential to reduce dependence on inorganic fertilizers, reduce production costs, and open up opportunities for the development of other organic waste-based products. Thus, this activity supports the implementation of sustainable agriculture and a circular economy at the community level.

Achieving the Sustainable Development Goals (SDGs), particularly SDGs 11 and 12, is a top priority requiring the development of eco-friendly products and community empowerment through waste management. The Induk Pelangi Waste Bank in Siak Sri Indrapura is an active community-based waste management facility that requires support for infrastructure improvement. This program was conducted during October 2025, beginning with the identification of partner needs focused on the revitalization of the administration building. The solution was implemented through an appropriate technology approach, where the physical renovation process served as a vehicle for the application of eco-friendly natural rubber latex-based paint research. This innovative product is the result of research collaboration between Politeknik Negeri Sriwijaya PSDKU Siak and the University of Riau. The paint application was carried out in two coats in a participatory manner on the building's interior and exterior. The results show that the administration building now appears neater and more presentable. Furthermore, this activity successfully demonstrated the viability of green technology and served as an educational medium that aligns the waste bank's infrastructure with the environmental values it promotes.

Eco-enzyme is a filtrate resulting from the fermentation of sugar, organic materials, and water, which is produced not only to reduce organic waste but also as a functional product. This study aims to examine the effects of sugar type and the eco-enzyme's fermentation duration on three key parameters: bacterial optical density, hydrogen peroxide concentration, and inhibition zone against Staphylococcus aureus and Escherichia coli. The bacterial optical density was determined from absorbance measured at 600 nm using a UV-Vis spectrophotometer, the hydrogen peroxide concentration was determined by permanganometric titration, and the inhibition zone of the eco-enzyme against Staphylococcus aureus and Escherichia coli was determined using the disc diffusion method. The results showed that the eco-enzyme fermented with molasses for one month had the highest bacterial optical density. Meanwhile, the highest hydrogen peroxide concentration was found in the eco-enzyme fermented with molasses for three months. In addition, the eco-enzyme fermented with molasses for three months exhibited the highest antibacterial activity against Staphylococcus aureus and Escherichia coli, with inhibition zones of 6.59 mm and 6.37 mm, respectively. Eco-enzymes fermented with granulated sugar, palm sugar, and molasses all showed antibacterial activity against Staphylococcus aureus and Escherichia coli. However, the highest antibacterial activity against both bacteria was observed in the eco-enzyme fermented with molasses for three months.

Eco-enzymes produced from fruit and vegetable waste are increasingly used for waste valorization and natural disinfection, but the combined effects of sugar type, fermentation duration and dilution on their quality remain unclear. This study examined eco-enzymes from mixed fruit peels prepared with granulated sugar, brown sugar and molasses, fermented for 1, 2 and 3 months, and diluted to 20%, 10%, 1%, 0.2% and 0.1%. Physicochemical properties (pH, TDS) and antibacterial activity against Staphylococcus aureus and Escherichia coli were measured; data were analysed by one-way ANOVA with Tukey’s test and Pearson correlation. Eco-enzymes were strongly acidic (≈3.5–3.9) at 20–10% and approached neutrality at 0.1%, with molasses-based formulations maintaining the lowest pH at high dilutions. TDS showed fermentation‑time‑dependent trends that differed between concentrated and dilute solutions. No inhibition was observed in month 1; activity appeared after ≥2 months and was highest at 3 months, with three‑month molasses eco-enzymes at 20% giving the largest inhibition zones and retaining activity at 0.1–0.2%. These findings identify molasses and extended fermentation as key levers to improve eco-enzyme performance as low-cost natural antibacterial agents.
