Abstract

Background: Our previous research successfully extracted astaxanthin from fermented Acetes shrimp (cincalok) using virgin coconut oil (VCO), resulting in astaxanthin-enriched VCO (VCOA). This innovative approach demonstrates the feasibility of incorporating VCOA into cosmetic preparations. In particular, its application in lip balm formulationsObjective: This study aimed to formulate a lip balm incorporating VCOA in combination with tengkawang butter.Method: The physical properties and sunscreen activity of the lip balm were evaluated as a function of storage duration at room temperature. The study examined the influence of varying concentrations and compositions of astaxanthin-enriched virgin coconut oil (VCOA) and illipe fat on the formulation. Key parameters assessed included homogeneity, pH stability, color stability, and melting point.Results: The test results indicated that a homogeneous lip balm was obtained when a high concentration of VCOA (15-30% w/w) was used and was stable for 28 days of storage. The acidity level (pH: 4.56-6.69) and melting point of the lip balm (50–67°C) have met the Indonesian National Standard. The presence of VCOA causes the lip balm to be yellow to orange. The resulting lip balm shows a sun protection factor (SPF: 51.1674 ± 0.0364) value with an ultra-protection category.Conclusion: In this study, astaxanthin was extracted from cincalok using VCO to produce VCOA, which was directly applied as a lip balm ingredient. The application of VCOA at the highest concentration (30%) yielded lip balm with excellent homogeneity, stable pH and melting point in accordance with SNI standards, the most pronounced color, and the highest SPF value.

Abstract

The use of mangrove leaves in functional beverages is increasingly popular due to their bioactive compounds, which have potential as natural antioxidant sources. This study aimed to analyze the antioxidant activity and organoleptic quality of tea infusions prepared from Acanthus ilicifolius and Rhizophora apiculata leaves. Leaf samples were collected from the coastal area of Kubu Raya Regency, vacuum-dried, ground, and prepared as tea infusions. Antioxidant activity was determined using the DPPH method, while organoleptic quality (appearance, aroma, and taste) was evaluated through a hedonic test with 10 panelists. The results revealed that A. ilicifolius tea exhibited higher antioxidant activity, with an IC₅₀ of 9.48 ppm, compared to R. apiculata at 16.36 ppm. Both values fall into the very strong category (IC₅₀

Abstract

The need for environmentally responsible extraction techniques has driven the development of green alternatives to conventional organic solvents. Deep eutectic solvents (DESs) offer a sustainable option due to their low toxicity, biodegradability, and simple preparation. In this study, a DES composed of glycine, glycerol, and water (1:11:15 molar ratio) was used as a green extraction medium to isolate bioactive compounds from the red algae (Eucheuma cottonii), providing an eco-friendly solution for efficient marine bioresource utilization. This final product offers a simplified process, as the resulting extract requires no further separation prior to application. The DES exhibited favourable physicochemical properties, including a pH of 5, density of 1300.14 kg/m³, viscosity of 0.0198 Pa·s, and a freezing point below 263.15 K. Phytochemical screening of the DES-based extract confirmed the presence of phenolic and terpenoid compounds. The extract was directly incorporated into sunscreen lotion formulations at concentrations ranging from 0 to 15% (w/w). All formulations showed good homogeneity, with the highest sun protection factor (SPF) value of 8.37 observed in the lotion containing 15% red algae extract. This research shows the success of extracting natural anti-UV ingredients in an environmentally friendly and efficient manner.

Abstract

The degradation of coral reef ecosystems requires rehabilitation efforts to support ecosystem recovery. One method of coral reef rehabilitation is through coral planula recruitment. Crustose Coralline Algae (CCA) that grow and attach to substrates serve as settlement sites for coral larvae, thereby supporting the recruitment process. This study aimed to determine the growth ability of CCA on concrete slab substrates with different compositions of constituent materials. The substrates used were concrete slabs made from different material mixtures. The differences in mixture composition were tested to determine the most suitable mixture for supporting CCA growth. The data collected included water quality parameters and the presence of CCA attached to the concrete slab substrates. The results showed that the 1:1 mixture produced concrete slabs with better physical conditions compared to the 3:1 mixture. Water quality parameters during the study were within ranges that supported marine organism growth, with salinity values of 36–39‰ and pH values of 7–8. Visual observations indicated that CCA was able to grow and attach to the constructed concrete slab substrates.

Abstract

Kuala Secapah Village serves as a prominent hub for capture fisheries along the coast of West Kalimantan. Alongside premium catches, local fishermen frequently haul trash fish (ikan rucah), that remains economically underutilized. Applying innovative and sustainable processing approaches to these marine resources can significantly generate added value for the community. This community service program aims to educate and train coastal women on upgrading these underutilized catches into competitive food products. The program was delivered in participatory workshop divided into two sessions: an instructional lecture and a hands-on culinary production practice. The intervention yielded substantial progress, with participants' technical knowledge skyrocketing from 64% to 99.6% regarding standardized and proper fish-processing techniques. Ultimately, this initiative successfully fosters local economic resilience by converting underutilized marine waste into high-value commodities.
