Analysis of Food Sanitation and Hygiene Practices in Eateries on Karya Wisata Street, Medan Johor District
Background: This study aims to analyze food sanitation and hygiene practices at food establishments on Karya Wisata Street, Medan Johor District. Method: A descriptive observational method was applied to 15 food establishments, including restaurants, food stalls, coffee shops, small eateries, and cafés. Data were collected through direct observation using a checklist based on the Indonesian Minister of Health Decree Number 1098/MENKES/SK/VII/2003, as well as brief interviews with food managers or handlers. The data were analyzed descriptively. Result: The results showed that most establishments met the requirements for clean water availability (93.3%), building and ventilation conditions (86.7%), and cleanliness of eating and cooking utensils (86.7%). However, several aspects remained below the required standards, including the use of personal protective equipment (PPE) by food handlers (40%), personal hygiene of food handlers (53.3%), availability of fire extinguishers (26.7%), wastewater disposal systems (60%), and pest control (60%). A total of 66.7% of establishments lacked proper wastewater drainage systems, while toilet cleanliness and food storage practices were also suboptimal. Overall, food sanitation and hygiene practices at the study location were fairly good, but improvements are still needed in basic sanitation and personal hygiene of food handlers. Conclusion: The study concludes that the implementation of food sanitation and hygiene on Karya Wisata Street has not yet fully complied with health standards. Therefore, regular supervision, continuous education, and increased awareness among managers and food handlers are necessary to prevent contamination risks and foodborne diseases. <div class="intersub-ai-chat" style="color-scheme: initial;

Quality of Environment Analysis Report at SDN 101820 Pancur Batu & SDN 106172 Desa Tuntungan II
Background: School sanitation plays an important role in creating a healthy, safe, and comfortable learning environment for students. Adequate sanitation facilities can help prevent environmental-related diseases and support students' health and well-being. This study aimed to describe the condition of environmental sanitation facilities at SD Negeri 101820 Pancur Batu and SD Negeri 106172 Desa Tuntungan II, Deli Serdang Regency, North Sumatra, Indonesia. Method: This study employed a descriptive qualitative design using direct observation and interviews. Data were collected on May 12, 2026, using an observation checklist covering clean water facilities, toilet facilities, handwashing facilities with soap (CTPS), wastewater management, and solid waste management. Result: The results showed that both schools generally met the standards for clean water facilities in terms of availability, accessibility, and physical quality. However, several deficiencies were identified in other sanitation components. Toilet facilities lacked some required supporting facilities, while CTPS facilities were not evenly available in all locations. Wastewater management was the most critical issue, as both schools did not use septic tanks that met the applicable standards and did not conduct routine desludging. In addition, solid waste management practices were inadequate due to the absence of waste segregation and limited waste disposal facilities. Conclusion: In conclusion, although clean water facilities met the required standards, improvements are still needed in toilet facilities, CTPS facilities, wastewater management, and solid waste management. Strengthening sanitation infrastructure and environmental health management is essential to create a healthier and safer school environment.
Analysis of Hygiene and Sanitation at Drinking Water Depots in the Tuntungan Subdistrict of Medan City
Background: Refillable Drinking Water Stations (DAMIU) are a widely used source of drinking water because they are easily accessible and relatively affordable. However, the quality of the drinking water produced is greatly influenced by hygiene and sanitation practices regarding the facility, equipment, and handlers/operators. This study aims to analyze the hygiene and sanitation conditions of DAMIUs in Medan Tuntungan Subdistrict, Medan City, based on the aspects of premises, equipment, and handlers/operators in accordance with Regulation of the Minister of Health of the Republic of Indonesia No. 43 of 2014. Method: This study employs a descriptive design with a qualitative approach. The study sample consisted of seven DAMIUs selected using purposive sampling. Data were collected through direct observation using a DAMIU hygiene and sanitation inspection checklist and analyzed descriptively. Result: The results showed that scores for the facility aspect ranged from 16 to 26; the equipment aspect scored 29 across all depots; and the handler/operator aspect scored between 15 and 18. Based on the cumulative assessment results, only one depot (14.3%) met the hygiene and sanitation requirements with a score of ≥70, while six depots (85.7%) did not meet the requirements. Non-compliance was most frequently found in the facility aspect, particularly regarding environmental conditions, ventilation, lighting, waste management, and disease vector control. All depots have met the equipment requirements; however, some operators were found to lack hygiene and sanitation certificates. Conclusion: It was concluded that most DAMIUs in Medan Tuntungan Subdistrict have not yet met hygiene and sanitation requirements; therefore, enhanced guidance, supervision, and training for managers and operators are needed to ensure the safety of the drinking water consumed by the community. <div class="intersub-ai-chat" style="color-scheme: initial;

Analysis of Environmental Sanitation at The Emerald One Swimming Pool in Medan Tuntungan District, Medan City
Background; Environmental sanitation is a crucial aspect of maintaining public health, particularly in public facilities used by many people, including swimming pools. Environmental sanitation conditions that do not meet health standards can increase the risk of disease transmission through water or the surrounding environment. This study aims to analyze the environmental sanitation conditions at the Emerald One Swimming Pool in Medan Tuntungan District, Medan City. Method: This study employed an observational design with a descriptive quantitative approach. Data collection was conducted through direct observation using a checklist based on environmental health regulations for swimming pools. The variables observed included the location, building, swimming pool, sanitation facilities, supporting facilities, as well as management and safety. Data analysis was performed descriptively by calculating the percentage of indicators that met and did not meet the requirements. Reslut: The results of the study show that, of the 35 indicators observed, 33 met the criteria and 2 did not. The overall compliance rate for environmental sanitation reached 94.3%. The aspects of location, buildings, swimming pools, supporting facilities, and management and safety achieved a 100% compliance rate, while the aspect of sanitation facilities achieved a 71.4% compliance rate. Conclusion: It can be concluded that the environmental sanitation conditions at the Emerald One Swimming Pool are very good. However, improvements are needed in the provision of handwashing facilities and soap to support clean and healthy living habits and to improve the overall quality of environmental sanitation.
Analysis of Hygiene and Sanitation Quality of Traditional Markets in Medan City
Background: Traditional markets are public facilities that play a vital role in community economic activity. Poor sanitation can increase the risk of spreading environmental-based diseases. This study aims to determine the hygiene and sanitation quality of traditional markets in Medan City and analyze their fulfillment of Healthy Market requirements. Method: This study used a descriptive design with an observational approach. Data were collected through direct observation using a checklist based on the Healthy Market indicators of the Indonesian Ministry of Health Regulation No. 17 of 2020 at five traditional markets in Medan City: Melati Market, Pancur Batu Market, Simpang Selayang Market, Karya Anak Bangsa (KBN) Market, and Tavip Binjai Market. Result: The study results showed that only Karya Anak Bangsa (KBN) Market met the Healthy Market category with a score of 78%. Meanwhile, Tavip Binjai Market scored 55.9%, Melati Market 52.5%, Pancur Batu Market 35.6%, and Simpang Selayang Market 30.5%, thus falling short of the minimum standard of 70%. The main problems identified included suboptimal waste management, poor drainage conditions, limited handwashing facilities, poor disease vector control, and inadequate implementation of PHBS. Conclusion: The quality of hygiene and sanitation of traditional markets in Medan City generally still does not meet the Healthy Market standards based on the Indonesian Minister of Health Regulation Number 17 of 2020. Efforts are needed to improve sanitation facilities and increase clean and healthy living behaviors to create a healthy, safe, and comfortable market. <div class="intersub-ai-chat" style="color-scheme: initial;

Sanitation and Healthy Living Behavior in Campus Boarding Houses: A Case of UINSU Medan
Background: Poor environmental sanitation can affect students’ learning motivation, concentration, and daily activities in boarding houses. This study aimed to assess environmental sanitation facilities and healthy behaviors among students living in boarding houses around the State Islamic University of North Sumatra, Medan Tuntungan. Method: This study used a case study approach involving 96 student boarding houses located around the Universitas Islam Negeri Sumatra Utara, Medan Tuntungan campus. Data were collected through direct interviews with boarding house residents and field observations using an observation form. The variables observed included housing conditions, clean water supply, wastewater drainage, garbage disposal facilities, and toilet availability. Result: The majority (85.4%) of boarding houses had tiled or ceramic floors. More than half of the boarding rooms lacked adequate ventilation. Refill drinking water was the main source of drinking water for most respondents (71.9%). All boarding houses had toilet facilities. However, disease vectors such as flies, mosquitoes, rats, and cockroaches were found in 69.8% of boarding houses. Most residents did not have a smoking habit (92.7%). Conclusion: Overall, most student boarding houses around the State Islamic University of North Sumatra, Medan Tuntungan, met the requirements for a healthy home. Nevertheless, improvements are still needed, particularly regarding ventilation and the control of disease-transmitting vectors to support a healthier living environment for students. <div class="intersub-ai-chat" style="color-scheme: initial;
