Abstract

Introduction: Humans use water to fulfill various daily needs. Each individual's water needs vary from one location to another and at each level of demand. The higher the standard of living in a place, the greater the need for water. Objective:  This study aims to examine the quality of water in several depots in Tanjung Morawa District. Method: The method used in this study is a gravimetric method in which the parameters measured determine the quality of water, namely TDS (Total Dissolved Solid) and TSS (Total Suspended Solid). Then measure the pH using a universal pH indicator, litmus paper and a pH meter. As well as the measurement of taste and turbidity. Result: The results of this study indicated that 8 out of 9 samples of TDS levels had levels higher than the maximum 2010 PERMENKES quality standard, namely 500 mg/L. TSS (Total Suspend Solid) is still lower when compared to the maximum standard content of refill drinking water stipulated by SNI (Indonesian National Standard) for clean water, which is 50 mg/L. The pH level is within normal limits, there is a sweet taste in drinking water and at turbidity levels clear drinking water has particles and is clear without particles.

Abstract

Standard Operating Procedures (SOP) serve as work guidelines to ensure the quality and consistency of laboratory services. Laboratory personnel compliance with SOPs is essential to minimize errors in the pre-analytical, analytical, and post-analytical stages that may affect the quality of examination results. This study aimed to analyze laboratory staff compliance with SOP  and its relationship with the quality of laboratory examination results at Grandmed Hospital, Lubuk Pakam. This research used a quantitative approach with an analytical cross-sectional design. The population consisted of all laboratory personnel at Grandmed Hospital Lubuk Pakam, totaling 30 people, selected using total sampling. Data were collected through questionnaires and observation, then analyzed using descriptive analysis and the Chi-Square test. The results showed that the level of laboratory personnel compliance with SOPs was in the high category. The Chi-Square test indicated that examination result quality, individual factors, and organizational factors had a significant relationship with SOP compliance (p < 0.05), while environmental factors showed no significant relationship (p > 0.05). In conclusion, compliance with SOPs plays an important role in maintaining the quality of laboratory examination results. Therefore, regular supervision, periodic SOP training, and continuous evaluation are needed to improve the quality of laboratory services
