Abstract

Drinking water quality is critical to public health. This article reviews studies that evaluated sulfate, pH, conductivity, and dissolved oxygen (DO) levels as key parameters in determining drinking water quality. Various water sources, such as tap water, wells, and bottled water, were analyzed in several studies. Sulfate was measured using the spectrophotometric method with BaCl2 reagent and absorbance was measured at a wavelength of 420 nm, while pH used a digital pH meter, conductivity was measured with a conductometer, and DO was measured with the Winkler method. The results showed significant variations in sulfate and dissolved oxygen levels between water sources. Some samples had pH that was below the standard, while sulfate levels in some samples were close to the maximum limit allowed by Permenkes No.492/MENKES/PER/IV/2010 (250 mg/L) and Permenkes No. 32/2017 (400 mg/L). DO proved to be the most sensitive parameter in detecting changes in water quality, followed by pH, and conductivity plays an important role in assessing drinking water quality as it provides an early indication of the concentration of dissolved ions that could indicate contamination, while sulfate is more effective in detecting certain contamination. The combination of these four parameters is important to ensure safe drinking water. This article is expected to guide research and assist water providers in maintaining drinking water quality standards.

Abstract

The Aedes aegypti mosquito is a species of mosquito that is known to be the main factor in the spread of Dengue Hemorrhagic Fever (DHF). This outreach aims to educate about the potential of the citronella plant as a natural mosquito repellent. Citronella (Cymbopogon nardus L.) is a plant that contains essential oils consisting of citronellal (27.87%), citronellol (11.85%), geraniol (22.77%), geranial (14.54%) , neral (11.21%). The citronellol compound contained in citronella essential oil has toxic properties that cause dehydration in animals, especially insects. In the Flagship KKN program Batch 50, KUBAR 12 Group, Mulawarman University innovated in making anti-mosquito spray from citronella plants and provided outreach and carried out direct practice with PKK women in Long Iram Seberang Village, numbering approximately 20 people.  The manufacturing process includes drying, cutting, boiling, and mixing with alcohol to maximize the effectiveness of mosquito repellent. The results of this activity show that the resulting spray can last for approximately three days at room temperature and up to seven days if stored in the refrigerator, making it a simple but effective solution in protecting families from mosquito bites. It is hoped that this activity will succeed in increasing public awareness of the importance of maintaining environmental cleanliness and identifying local habits that can naturally reduce the risk of spreading dengue fever
