Abstract

The number of watercrafts in the sea will have an impact on the amount of waste lubricant oil that is discharged into the sea, which ultimately results in pollution. The increasing level of hazardous and toxic materials (B3 waste) is concerned to have a wider impact on public health and environment quality. One of the B3 wastes that requires special handling due to its high quantities is used lubricating oil. Utilization and processing of waste lubricant oil discharged from the ship is an alternative that can be applied to reach efficient consumption of petroleum which is shrinking from year to year. Therefore, we need a processing method that can reduce the pollutants generated from the waste, one of which is the Acid Clay Treatment method. This treatment aims to determine the best conditions for reducing heave metal lead (Pb) through Acid Clay Treatment method and to assess the decrease in Pb concentration contained in used lubricating oil from ship. The adsorbent used was clay that has been activated with sulphuric acid. The processing of used lubricating oil was carried out using three variations, including adsorbent concentration, contact time, and acidity (pH). The test results of used oil lubricating oil processing were 15 gram of adsorbent concentration, 90 minutes of contact time, and pH 4. The Pb reduction efficiency obtained from Acid Clay Treatment method in the best conditions was 53.72%.

Abstract

Bar soap is a skin cleansing preparation in solid form made from soap with the addition of desired ingredients, be they natural ingredients or dangerous chemicals. Hydroquinone is a dangerous chemical which, if added excessively to facial cleansing soap, can cause hyperpigmentation on the skin. The use of hydroqunon according to BPOM regulation no. 18 of 2015 is included in the class of hard drugs. Hydroquinone is prohibited from being used because it has dangerous side effects such as skin irritation, facial redness such as a burning sensation and can also cause black spots on the face. This type of research is a laboratory observational study which aims to analyze the hydroquinone levels in bar facial cleansing soap that is sold at the Minasa Maupa market, Sungguminasa, Gowa Regency. The sampling technique was carried out by purposive sampling. The samples were tested qualitatively using the thin layer chromatography method and if positive results were obtained, quantitative analysis was continued using the UV-Vis spectrophotometry method. From the research results of 10 samples of bar facial cleansing soap, 1 sample was positive for containing hydroquinone, indicated by the presence of stains when observed under a UV lamp with an Rf value of 0.427, while the standard Rf value was 0.438. Meanwhile, the other 9 samples did not contain stains so the Rf value could not be calculated. Next, the positive samples were continued with quantitative analysis to obtain a hydroquinone level of 0.013%. The levels obtained were stated to be still below the standards set by BPOM No. 18 of 2015 which amounted to 0.02%

Abstract

Gallons of refilled drinking water usually don't run out in a single use but run out in a few days or even up to 1 to 2 weeks, depending on usage, and stored at room temperature (27-29 °C). Drinking water that is stored for a long time will allow the growth of microorganisms which are influenced by environmental factors, namely temperature conditions and oxygen supply during storage. This affects the pH and total organic content of drinking water. Inspection of the quality of water products according to the Regulation of the Minister of Health of the Republic of Indonesia Number 492/MENKES/PER/IV/2010, which is a maximum organic matter content of 10 mg/L. According to chemical parameters, drinking water must not contain inorganic and organic substances exceeding the standard with a pH value between 6.5-8.5. The purpose of this study was to determine the levels of organic substances in RO (Reverse Osmosis) refill drinking water. This type of research is a laboratory experiment using purposive sampling technique. The results showed that the average organic content of refilled drinking water with a storage period of 0 days was 1.839 mg/L, 3 days was 2.57 mg/L, and 6 days was 5.28 mg/L. Thus, the levels of organic substances in drinking water are based on storage time of 0, 3, and 6 days using the spectrophotometric method according to the maximum drinking water quality standard.

Abstract

Typhoid fever is an acute systemic disease caused by the bacterium Salmonella typhi. Salmonella typhi found in the small intestine will multiply and then produce endotoxin, where the endotoxin produced is a lipopolysaccharide complex and is considered to play a key role in the pathogenesis of typhoid fever. If it enters the body, it will cause the body's condition to become weak, making it easier for Salmonella typhi bacteria to attack body tissues such as the liver and cause SGPT levels to increase. Liver damage in patients with typhoid fever in the form of changes in hepatomegaly, jaundice, biochemical, and histopathological changes. This study aims to provide an overview of Serum Glutamic Pyruvic Transaminase (SGPT) levels in patients with typhoid fever at Haji General Hospital, Makassar City. The method in this study was descriptive, with a sample population of 10 typhoid fever patients. The sampling technique used is Random Sampling. From a study conducted on 10 samples of typhoid fever patients, it was found that 6 samples had normal SGPT levels, and 4 samples had high SGPT levels, with the highest level being 95.2 µl and the lowest level being 15.9 µl. It can be concluded that the increased levels of SGPT in patients with typhoid fever is due to strenuous physical activity and taking certain drugs which can trigger increased levels of SGPT.
