Abstract

The use of natural ingredients as components in eco-friendly cleaning products is an important alternative for reducing the impact of synthetic surfactants on human health and aquatic environments. This study aims to analyze the effect of adding pedada mangrove fruit extract (Sonneratia caseolaris) on the physicochemical characteristics of dishwashing soap as an eco-friendly cleaning agent. Extraction was performed using the maceration method with 96% ethanol, and the extract was formulated into liquid dish soap at varying concentrations of 0%, 10%, 15%, and 20%. The testing included phytochemical screening, viscosity, pH, homogeneity, organoleptic evaluation, and foam stability. The results of the phytochemical screening indicated the presence of flavonoids, tannins, and saponins, which have potential as natural antimicrobial agents. The addition of the extract caused a decrease in viscosity from 3550.21 cP to 932.95 cP as the extract concentration increased; however, all formulations still met the SNI 4075-2:2017 standard. The pH ranged from 6.06 to 6.44, which is considered safe for household use and relatively compatible with the skin’s physiological balance. Foam stability increased from 81.82% to 92.59% due to the presence of saponins, which act as natural surfactants. All formulations exhibited good homogeneity without phase separation. The formulation with a 15% extract concentration produced the most optimal and stable physical characteristics. This study indicates that pedada fruit extract has the potential to be developed as a coastal bio-based cleaning biomaterial that supports the concepts of green technology, environmental health, and the sustainability of aquatic ecosystems.

Abstract

ABSTRACT Household medicinal plants (TOGA) represent an initiative to utilize plants with medicinal properties to improve public health through self-reliance. The use of medicinal plants can serve as an easily accessible and relatively safe alternative to traditional medicine for addressing various minor health complaints. However, the utilization of medicinal plants in the community remains suboptimal due to a lack of knowledge regarding the types of medicinal plants and how to use them. This community service activity aims to improve the community’s knowledge and skills in developing family medicinal plants as a preventive measure to maintain health. Implementation methods include health education on the benefits of medicinal plants, training in planting and maintaining TOGA, and community assistance in managing TOGA gardens. The results of the activity indicate an increase in community knowledge regarding medicinal plants as well as increased community participation in the utilization of family medicinal plants. The TOGA development program can serve as a strategy to enhance community self-reliance in maintaining health. Keywords: Family Medicinal Plants, Community Empowerment, Preventive Health, Public Health. ABSTRAK Tanaman obat keluarga (TOGA) merupakan salah satu upaya pemanfaatan tanaman yang memiliki khasiat obat untuk meningkatkan kesehatan masyarakat secara mandiri. Pemanfaatan tanaman obat dapat menjadi alternatif pengobatan tradisional yang mudah diperoleh serta relatif aman digunakan untuk mengatasi berbagai keluhan kesehatan ringan. Namun, pemanfaatan tanaman obat di masyarakat masih belum optimal karena kurangnya pengetahuan mengenai jenis tanaman obat serta cara pemanfaatannya. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pengetahuan dan keterampilan masyarakat dalam mengembangkan tanaman obat keluarga sebagai upaya preventif dalam menjaga kesehatan. Metode pelaksanaan meliputi penyuluhan kesehatan mengenai manfaat tanaman obat, pelatihan penanaman dan pemeliharaan TOGA, serta pendampingan masyarakat dalam pengelolaan kebun TOGA. Hasil kegiatan menunjukkan adanya peningkatan pengetahuan masyarakat mengenai tanaman obat serta meningkatnya partisipasi masyarakat dalam pemanfaatan tanaman obat keluarga. Program pengembangan TOGA dapat menjadi salah satu strategi dalam meningkatkan kemandirian masyarakat dalam menjaga kesehatan.
