Abstract

The biodiversity owned by a country is a gift that must be appreciated. The potential of these natural resources can be used as research material to overcome existing problems. One of them is about how to answer the challenges of the effects caused by the use of chemicals that can harm the environment and surrounding living things. Therefore, it is necessary to modify the use of chemicals to be more optimal and of course safe both in use and effects. Modification of the particle size of a substance provides benefits because the size of a substance becomes smaller (nanoparticles) so that it will expand the surface of the contact substance. Several applications of the use of nanoparticles of a substance as a drug target carrier agent, sensor, increased bioavailability, and reduced effects of a substance have been carried out by several researchers. This study aims to evaluate the continuation of the potential of namnam leaves which have quite good bioactivity as antimicrobials. The method used is laboratory experimental. The research stages include the manufacture of namnam leaf extract, phytochemical test of the extract, and antimicrobial activity test. The extract was made by maceration using methanol for 3x24 hours and produced a yield of 11.2%. The results of the phytochemical test showed that the methanol extract of namnam leaves contains active compounds such as flavonoids, saponins, phenolics, steroids, and tannins. The content of these active substances has the potential as antimicrobials. The preliminary bioactivity test was carried out using the well method which produced inhibition zones of 15 mm, 18 mm, and 18 mm. The value of this inhibition zone is included in the sensitive category according to the CLSI data division.

Abstract

Background: Dermatitis is a common skin health problem among farmers and is associated with personal hygiene practices in humid working conditions and exposure to agricultural chemicals. Objective: This study aims to analyze the relationship between hygiene practices and the risk of dermatitis in the feet of orange farmers in Berastag. Methods: The study design employed a descriptive-analytical approach using a cross-sectional method. The study sample consisted of 30 orange farmers selected via purposive sampling. Data were collected through interviews, observation of hygiene behaviors (foot washing, use of personal protective equipment/PPE, and workplace cleanliness), as well as clinical and mycological laboratory examinations. Results: The study found that 13 respondents (43.3%) had dermatitis, while 17 respondents (56.7%) did not. A total of 19 farmers (63.7%) were in the habit of washing their feet after work, 9 people (30%) used PPE, and 12 people (73.4%) maintained workplace hygiene. Analysis indicated a trend that farmers who did not wash their feet were more likely to experience dermatitis (72.7%) compared to those who did (26.3%). The use of PPE and workplace hygiene were also associated with the occurrence of dermatitis. Laboratory identification revealed pathogenic fungi such as Trichophyton rubrum and Candida albicans, which were implicated in the cases of dermatitis. Conclusion: Hygiene practices are associated with the risk of dermatitis among citrus farmers.

Abstract

Background: Background: Citrus fruits are a natural source of vitamin C, which acts as an antioxidant, boosts immunity, supports collagen synthesis, aids in iron absorption, and contributes to wound healing and cellular function. Vitamin C deficiency can lead to scurvy, a condition characterized by symptoms such as fatigue, anemia, bleeding gums, and impaired wound healing. Therefore, analyzing vitamin C levels in food, particularly fruits, is important to determine their contribution to meeting daily nutritional needs. Objective: To determine and compare vitamin C levels in several types of citrus fruits. Methods: The study employed a quantitative approach using the iodometric titration method, known for its simplicity, accuracy, and widespread use in vitamin C analysis. The study samples consisted of four types of citrus fruits: lemon, lime, kaffir lime, and sweet orange. Results: The analysis results showed that vitamin C levels varied among the orange varieties, with the highest value found in lime at 0.08 mg/25g, followed by lemon at 0.06 mg/25g, sweet orange at 0.06 mg/25g, and kaffir lime at 0.05 mg/25g. Conclusion: Variations in vitamin C content are influenced by differences in citrus varieties, ripeness levels, and the characteristics of the soil and growing environment, all of which affect the chemical composition of each fruit.
