Abstract

PLTD (Pembangkit listrik tenaga diesel) merupakan penyumbang  emisi tinggi yang  berkontribusi pada polusi udara. Perancangan silica gel filter untuk mereduksi emisi, berbasis adsrorpsi pada parameter SO₂, NOₓ, NO₂, CO₂, dan CO diharapkan membantu menekan polusi udara, meningkatkan kualitas lingkungan, dan memenuhi regulasi pemerintah. Untuk itu dilakukan pengujian pada genset 101-500 KW. Filter dibuat dengan adsorben silica gel dan karbon aktif, diuji di Laboratorium Lingkungan NTB mengikuti standar emisi Indonesia. Data dikumpulkan melalui observasi, uji emisi, dan regresi analisis untuk menilai efektivitas filter. Hasil uji emisi pada prototipe perancangan silica gel filter mendapatkan hasil signifikan dengan persentase efektivitas NOₓ mencapai 35,8% sedangkan  CO sebesar  22,5%. Selain itu emisi yang tidak dilakukan uji laboratorium seperti SO₂ mengalami penurunan hingga 87,5%, NO₂ sebesar 87,2%, dan sedangkan CO₂ sebesar 94,7%. Efektivitas silica gel dipengaruhi oleh suhu, kondisi mesin ( daya hisap) dan ukuran pori-pori adsorben. Ini menunjukkan bahwa filter silika gel dapat mereduksi emisi dan meningkatkan kualitas udara.

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

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.
