Abstract

The Lae Soraya River, which crosses two provinces, namely North Sumatra and Aceh, is utilized as a raw water source by some communities in the Rundeng District, Subulussalam City, for hygiene and sanitation needs directly without treatment and is also used as a raw water source for drinking. Considering this fact, the researcher studied the water pollution index of this river based on the Minister of Health Regulation number 32 of 2017 and Government Regulation number 22 of 2021, class I. The parameters in this study include temperature, odor, color, pH, Total Dissolved Solids (TDS), Turbidity, and Nitrate. This research aims to provide information on the quality status of the Lae Soraya River so that it can be used for pollution management and control. The method used in this study involves the measurement of the parameters at 7 sampling points through the grab sampling method and the water quality status of the Lae Soraya River is analyzed using the pollution index method (Minister of Environment Decree number 115 of 2003). The results obtained based on the tested parameters are the temperature ranges from 28ºC to 29ºC, the water has a slightly musty odor and a greenish color, pH ranges from 7.8 to 8.4, TDS ranges from 70mg/l to 74mg/l, turbidity ranges from 18.72NTU to 29.17NTU, and Nitrate testing values range from 7.85mg/l to 16.1mg/l. Based on the results, it is found that the Lae Soraya River has a mild pollution status. Considering the testing values and determination of water quality status, the river is not suitable for direct use for hygiene and sanitation needs or as a raw water source for drinking.

Abstract

Generally, the volume of water used for wudu varies for each person, with an average of 6 liters per person per time, depending on the habit of how one opens the tap and the water flow rate. However, according to hadith, the Prophet Muhammad Saw performed wudu using only one mud of water (625 milliliters). Water conservation during wudu can be achieved by reducing the amount of water discharged from the tap. In this study, an automatic wudu faucet prototype was designed, equipped with infrared sensors, a buzzer, ultrasonic technology, and controlled by an Arduino Uno microcontroller. In this system, the faucet will only open when there is an object or a hand/foot beneath it and will close when no object is detected anymore. Additionally, the system will produce a sound indicating that an object is approaching within a distance of 10 cm. This prototype is able to increase the efficiency of water usage during wudu by 67%. The average water usage for wudu using a manual faucet by the subjects was found to be 4.86 liters per person per time. After using the automatic wudu faucet prototype, the average water usage was reduced to 1.624 liters per person per time. Water conservation, even in small activities like wudu, can contribute to preserving water resources and ensuring their availability on Earth.
