Abstract

The management of medical liquid waste is an important aspect in efforts to maintain environmental quality and public health. This study aims to analyze the effectiveness of medical liquid waste management at the Sakra Barat Health Center, East Lombok Regency, based on quality standards set forth in the Ministry of Environment Regulation No. 68 of 2016. The research method used is a quantitative approach with testing of waste samples before and after treatment in the Wastewater Treatment Installation (IPAL). The results show that before treatment, several waste parameters such as BOD (139 mg/l), COD (825 mg/l), and TSS (282 mg/l) exceeded the established quality standards. However, after treatment, these values significantly decreased and met the quality standards, with TSS values of 2.50 mg/l at an effectiveness percentage of 99.11%, BOD of 1.53 mg/l at an effectiveness percentage of 98.90%, COD of 38.0 mg/l at an effectiveness percentage of 95.39%, and a pH value of 7.26. This indicates that the IPAL at the Sakra Barat Health Center is effective in processing medical liquid waste, ensuring that the discharged waste is safe and does not pollute the environment.

Abstract

The process of re-filtering or filtration of sample water in the IPA IKK Pandan Duri reservoir tank is due to the parameter levels that sometimes do not meet the quality standards according to PERMENKES No. 2 of 2023 concerning the Standards for Water Needs for Hygiene and Sanitation. Several factors causing the high levels of parameters in the water that has been filtered by the PDAM unit branch include, among others, the insufficient amount of filtration media used, corrosion in the filtration equipment (WTP), and/or the reservoir not being cleaned regularly. This leads to the filtered clean water becoming re-contaminated, so sometimes the clean water ready to be supplied to the communities in Desa Keruak and Jerowaru gets contaminated again. This research uses experimental research methods and descriptive analysis. Results obtained: pH levels experienced a concentration decrease of 0.22 mg/l with an effectiveness of 50.76%; NTU with a decrease of 12.44 mg/l with an effectiveness of 97%; TDS levels decreased by 315 mg/l with an effectiveness of 83.72%; Fe reduction was 0.963 mg/l with an effectiveness of 98%; lastly, the NO3 parameter with a decrease of 21.98 mg/l and the highest effectiveness reaching 99%.

Abstract

Wastewater from washing restaurants contains many hazardous substances that can reduce environmental quality. Pollutants contained can be BOD, COD TSS, Ammonia, and Oil and Fat. Restaurant liquid waste needs to be treated first before being discharged into the environment or water bodies. One method of wastewater treatment that is quite effective in neutralizing hazardous substances is the downflow filtration system. This study aims to determine the effectiveness of the downflow filtration method of zirconia sand, zeolite stone, activated charcoal and cotton media in reducing parameters contained in restaurant liquid waste such as pH, BOD, COD, TSS, Ammonia, and Oil and Fat Based on Permen LHK No. 68 of 2016.. The results of this study are that the processing of restaurant wastewater with a downflow filtration system is quite effective in reducing pH, BOD, COD TSS, Ammonia and Oil and Fat parameters. The results can be seen, namely pH before processing 7.4 Mg / L and after processing 7.4 Mg / L, BOD 2.79 Mg / L after processing 1.53 Mg / L, COD 36.7 Mg / L after processing 51.1 Mg / L, TSS 35.0 Mg / L after processing 4.00 Mg / L, Ammonia 32.0 after processing 0.222 Mg / L, Oil and Fat 32.0 after processing 1.00. From the parameter values of the processed results, the downflow filtration values of pH, BOD, TSS, Ammonia and Oil and Fat have met the standard quality standards, while COD has not met the standard quality standards for the average reduction results according to the Regulation of the Minister of Environment and Forestry No. 68 of 2016 concerning the Domestic Waste Quality Book.

Abstract

Livestock is an agricultural sub-sector that plays a very important role in providing food needs, especially animal protein. The more chickens there are, the more manure will be produced so that the Ammonia Gas (NH3) will be higher. The research method used is the observational research method, which is descriptive analytical with a cross-sectional approach. Based on the results of observations made on broiler chicken cage workers, most respondents agreed that the smell of ammonia (NH3) in broiler chicken cages disturbed their sense of smell. Most respondents had the answer. For measurements at points 2 and 3, there was a lower average NH3 concentration., this is because there is not too much broiler chicken waste and there is not too much activity in the cage at points 2 and 3 so the NH3 concentration is low. Most of them had answers agree with values ​​38, 38, 38, 38, 39, 43, 45, 48, and some had answers quite agree with values ​​30 and 33. It can be concluded that exposure to ammonia gas (NH3) is high in the environment. Broiler chicken cages have a negative impact on workers' sense of smell, and can increase the risk of partial anosmia (partial loss of the ability to smell) in broiler chicken cage workers. As many as 80% of respondents agreed that impaired sense of smell was caused by the smell of ammonia. These disorders not only reduce workers' quality of life, but also have the potential to affect their performance in carrying out daily tasks.

Abstract

The limited availability of clean water, unable to meet the ever-increasing demand, raises concerns for the community. Therefore, an analysis of the clean water balance is necessary to ensure an adequate water supply. This study aims to calculate the availability of clean water, assess water needs, and analyze the clean water balance in Joben Hamlet, Pesanggrahan Village, Montong Gading Subdistrict, East Lombok Regency, in 2024. The research method used was a descriptive quantitative approach, with data comprising primary and secondary sources. Data collection techniques include observation, direct field measurements, interviews with local residents, and documentation related to water resources in the area. Data analysis techniques involve calculating water availability, water needs, and the status of the water balance in the hamlet. The study results show that the primary water sources in Joben Hamlet come from springs, rivers, water reservoirs, and groundwater. These sources were sufficient to meet domestic and non-domestic water needs. The water requirement per household is calculated to be 165 liters/day, assuming an average household size of five people, each needing 33 liters per day. The total domestic need for 226 households amounts to 37,290 liters per day. The total water availability recorded over one day is 3,457,368.248 liters, while the water requirement is only 1,767.227 liters. Thus, there is a surplus of 3,455,601.02 liters per day. This balance indicates that the area still has abundant water resources, capable of meeting future community needs and supporting other economic sectors.
