However, because of the current high population and activities, industrial and domestic garbage are being dumped straight into the Musi River. The purpose of this research was to study the variables that affect the processing of the Musi Riiver Water Samples to get the quality standard requirements of the third-grade river water. Water is filtered using a slow sand filter with a 50–70 cm sand height fluctuation and four different UV irradiation times 15, 30, 45, and 60 minutes. The results of this investigation showed that 2% DO was obtained for the filtration of Musi River water using a slow sand filter with a height of 70 cm sand. BOD5 and COD degradation were determined to be 82% and 93%, respectively. Meanwhile, 29/100 ml of E. Coli was discovered for the UV radiation therapy after a 60-minute irradiation period. Keywords: musi river, filtration, slow sand filter, UV radiation ABSTRAK Air Sungai Musi biasanya digunakan untuk memenuhi kebutuhan sehari-hari. Namun karena tingginya jumlah penduduk dan aktivitas saat ini, sampah industri dan domestik banyak dibuang langsung ke Sungai Musi. Tujuan penelitian ini adalah untuk mempelajari variabel-variabel yang mempengaruhi pengolahan Sampel Air Sungai Musi untuk mendapatkan persyaratan baku mutu air sungai kelas tiga. Air disaring menggunakan saringan pasir lambat dengan fluktuasi ketinggian pasir 50–70 cm dan empat kali penyinaran UV yang berbeda yaitu 15, 30, 45, dan 60 menit. Hasil penelitian menunjukkan DO 2% diperoleh untuk penyaringan air Sungai Musi menggunakan slow sand filter dengan ketinggian pasir 70 cm. Degradasi BOD5 dan COD ditentukan masing-masing sebesar 82% dan 93%. Sedangkan E. Coli sebanyak 29/100 ml ditemukan setelah radiasi UV setelah masa penyinaran 60 menit.

Based on the results of the exploration by (Abia et al., 2016), it was concluded that the river is largely defiled by index and pathogenic organisms and the use of undressed river water will pose a high implicit threat of infection. The threat of infection due to the use of this water for particular and ménage purposes increases in the stormy season compared to the dry season. Most importantly, conditioning that affects deposition disturbance will increase the threat of infection for river addicts.The topmost hazard associated with the ingestion of water is the microbial risk due to I. Introduction Musi River is a river that exists in the province of South Sumatera. With a length of 750 km, this river is the longest river in Sumatra Island and separated from Palembang City into two parts. Ampera bridge that became an icon of Palembang city across this river. Since the area of the Sriwijaya kingdom until now, this river is famous as the main transportation for society. This river separated the city Palembang into two parts: an area that is downstream across in the north part and across the pit in the south part. Musi River with the -152- Jurnal Engine: Energi, Manufaktur, dan Material e-ISSN: 2579-7433 Sriwijayasih, Novianarenti, Agustina, Nasir, Leonard, Rand & Kusminah, Vol.8,No.2,November 2024, Pp:152-160 water impurity by human and/ or beast feces. Drinking polluted water results in thousands of deaths every day, substantially in children under five times of age in developing countries. These conditions caused by consumption of polluted water, and poor hygiene practices are the leading causes of death among children worldwide, after respiratory conditions. Therefore, lack of safe drinking water force, essential sanitation and hygienic practices are associated with high morbidity and mortality from excreta related affections. Based on Public Health Hazards Due to Unsafe Drinking Water article, Ensuring water quality and safety requires the active participation of all stakeholders in the medical community. Nevertheless, the maturity of healthcare professionals have entered limited training in the evaluation of waterborne conditions. Lack of safe water to meet diurnal requirements is a reality for numerous people around the world and has serious health consequences. The situation is getting worse due to population growth, urbanization, and increased domestic and artificial water use described by (Pal et al., 2018). Contact with drinking or unsafe water can cause problems or serious risk to human health . Hence, water quality is a critical issue to insure public health. Since water is nearly associated with diurnal mortal conditioning, delivering safe drinking water is one of the important public health precedences. Acceptable access to safe water, perfecting quality of water source, treating ménage water, and storing it safely, acceptable sanitation installations, and encouraging good hygiene practices, especially hand washing can help waterborne conditions (Bain et al., 2014). The growth of the human population has caused the increase of human needs. To fulfill the human needs which vary, societies built their houses at the river side. In certain areas in Indonesia, the scarcity of clean water still frequently appears, including in big cities and finally the society utilizes water to survive so they are using water at the riverside which is containing dirt. The Musi River is a natural resource that is becoming one of the main lines of trade and the largest supplier of water for the residents of South Sumatra. Regional Water Company (PDAM) of Tirta Musi utilizes the Musi River as a source of raw water to fulfill the water needs of the population. The total customer of PDAM Tirta Musi has as much as 198.000 connections, or equal to 95% of the needs of clean water in Palembang. The need for clean water in the city of Palembang increased to 272 m3/day during the dry season. The river conditions declining quality and the quantity can be seen from the watershed which has increased critically. Currently, At the upper part of the river Musi there is a crowded residential area in the city of Palembang wi (...truncated)
