Abstract

This study investigates the potential of using domestic wastewater as a growth medium for Chlorella sp. and examines how it affects water quality over a period of 24 days. The experiment was conducted using a Completely Randomized Design (CRD) with a single factor: four levels of domestic wastewater concentration0%, 25%, 50%, and 75%each tested in three replicates.The results showed that the highest biomass production occurred on day 8, reaching 0.337 mg/L in the 75% wastewater treatment (TR3), while the lowest was observed in the control group (C) at 0.210 mg/L. Statistical analysis using ANOVA followed by the Tukey test confirmed that the differences between treatments were significant (p 0.05). Correlation analysis showed a strong positive correlation between biomass and dissolved oxygen (DO, 0.949) and temperature (0.626), indicating that optimal light intensity and nutrient availability promote photosynthesis and biomass growth. In contrast, phosphate was negatively correlated with temperature (-0.738), suggesting that higher temperatures accelerate phosphate uptake by Chlorella sp. The study concludes that cultivating Chlorella sp. using domestic wastewater presents a sustainable solution for both biomass production and wastewater treatment. The microalgae help remove excess nutrients like nitrogen and phosphorus, enhancing water quality. However, as the algae decompose, they can also contribute to higher biological oxygen demand (BOD). This dual role underscores the promising potential of microalgae in promoting ecological wastewater management while supporting sustainable biomass production.Keywords:BiomassChlorella sp.Photobioreactorwastewater

Abstract

Herbal teas derived from local plant resources have considerable potential for development as functional beverages; however, their physical characteristics are strongly influenced by raw material composition. This study aimed to evaluate the effect of the proportion of rambusa leaves and sappan wood on the physical characteristics of rambusa-sappan herbal tea. A completely randomized design was applied with six sappan:rambusa ratios (0:100, 10:90, 20:80, 30:70, 40:60, and 50:50) and three replications. The analyzed parameters included moisture content, water absorption capacity, solubility percentage, pH, and color characteristics (L*, a*, b*). The results showed that formulation significantly affected all evaluated physical parameters. Increasing the proportion of rambusa tended to enhance water absorption capacity and produced a lighter infusion color, whereas higher sappan proportions increased solubility and red color intensity due to the presence of water-soluble pigments and phenolic compounds. All samples exhibited low moisture content and neutral to slightly acidic pH, supporting product stability during storage. The interaction between leaf-based and wood-based materials governed the rehydration behavior and visual characteristics of rambusa-sappan herbal tea in a complementary manner. Overall, rambusa-sappan formulation plays an important role in determining physical quality and visual appearance and can serve as a basis for developing functional beverages from local plant resources with controllable characteristics.
