Abstract

Kelurahan Sepan is one of the villages located in the Penajam District, Penajam Paser Utara Regency. One of the issues in Sepan Village is the lack of infrastructure, which impacts the mobility and daily life of the community. A specific problem is the absence of a waste disposal site (TPS), leading residents to dispose of waste carelessly. This activity aims to reduce waste accumulation by utilizing organic household waste as raw material for making easy and appropriate fertilizers. The method used includes socialization and direct practice, where the socialization is divided into three materials: an explanation of the types of waste, the procedure for making eco-enzyme, and biopore. The outcome of this activity is the successful implementation of socialization and direct practice among the residents of Sepan Village. Some residents understood the materials presented and successfully applied eco-enzyme and biopore techniques in their environment after the activity was completed.

Abstract

Sirsdak (Annona muricata L.), is a plant whose fruit is edible and the leaves and fruit have been used by the community as traditional medicine. This study aims to test the chemical content, toxicity, and antioxidant activity of ethanol extract of soursop leaves (Annona muricata L.). Phytochemical tests were carried out to identify bioactive compounds contained in the extract, while toxicity tests used the Brine Shrimp Lethality Test (BSLT) method to determine toxic potential. Antioxidant activity was evaluated using the DPPH (2,2-diphenyl-1-picrylhydrazyl) method to measure the ability to scavenge free radicals. The results showed that the ethanol extract of soursop leaves contained steroid, saponin and quinone compounds, had significant toxicity potential with an LC50 value of 31.19 ppm, and showed weak antioxidant activity with an IC50 value of 111.27 mg/L Keywords : Soursop Leaves., Phytochemical Analysis Antioxidant and Toxicit.

Abstract

Excessive exposure to ultraviolet (UV) radiation can cause various negative effects on the skin, including erythema, hyperpigmentation, premature aging, and even skin cancer. The use of natural-based sunscreens is considered a safer and more environmentally friendly alternative to synthetic sunscreens. This study aimed to determine the Sun Protection Factor (SPF) of the crude extract and fractions of surian leaves (Toona sinensis (Juss.) M. Roem) using a UV-Vis spectrophotometer based on Mansur's equation. Extraction was carried out by maceration with 96% ethanol, followed by liquid-liquid partition using solvents with different polarities, namely n-hexane, ethyl acetate, and ethanol-water. Phytochemical screening showed the presence of bioactive compounds such as phenolics, flavonoids, quinones, tannins, and steroids, which are known to have photoprotective potential. The SPF test results revealed that the ethyl acetate fraction had the highest SPF value of 34.34 at a concentration of 250 ppm, classified as ultra-protection. The ethanol extract and ethanol-water fraction also showed high SPF values of 31.02 and 24.51, respectively, while the n-hexane fraction had the lowest SPF value. These findings indicate that surian leaves, particularly the ethyl acetate fraction, have promising potential as an active ingredient in natural sunscreen formulations.
