    Traditional markets are centers of social and economic interaction that provide daily necessities but often face environmental sanitation challenges, such as piles of waste that produce unpleasant odors. An unhealthy market environment can negatively affect the physical health and well-being of visitors and may serve as a breeding ground for disease vectors such as flies. This study aims to analyze vendor behavior (knowledge, attitudes, and practices) regarding market sanitation, assess the sanitation conditions, and measure the fly density in the dry area of Tavip Market, Binjai Kota District. This research is a descriptive survey using observational and interview approaches. The population consisted of all dry stall vendors at Tavip Market (121 people), with a sample of 55 vendors selected using purposive sampling. Primary data were obtained through interviews and fly density measurements using a fly grill. The results showed that the majority of vendors in the dry area were female (74.5%), aged 18–40 years (61.8%), and had been working for 1–10 years (83.6%). Most vendors had moderate knowledge of market sanitation (43.6%), but their attitudes were predominantly poor (96.4%). Likewise, the majority of vendor practices regarding market sanitation were also poor (47.3%). Overall, Tavip Market's sanitation was found to not meet health standards, with only 29.71 percent compliance based on the Indonesian Ministry of Health Regulation No. 17 of 2020. Fly density measurements in the dry area indicated a moderate category (3–5 flies/block/grill), with an overall average of 9.28. The highest fly density was found at the Temporary Waste Disposal Site (TPS), with an average of 28 flies (very high category). Vendors are expected to maintain market cleanliness by disposing of waste properly and providing individual trash bins at each stall/stand that meet the required standards.143 PagesSkripsi Sarjan

    No full text
    This study examines the phenomenon of Toyoko Kids, referring to groups of youths who gather near the Toho Cinema building in Tokyo, Japan. These Toyoko Kids are teenagers who have run away from home due to domestic violence, economic hardship, social media influence, and a lack of protection. The aim of this research is to understand the Toyoko Kids phenomenon in Kabukicho, Tokyo, and to identify the factors that lead Japanese teenagers to become Toyoko Kids. This study uses a descriptive qualitative method and literature review. Data were collected from documentation studies such as books, websites, articles, videos, and images as supporting sources. The analysis applies phenomenological theory, impact theory, and factor theory. The findings show that Toyoko Kids in Kabukicho are predominantly female teenagers who tend to support a lifestyle disconnected from structured environments, often involving alcohol and drug use. Many come from problematic families and join Toyoko Kids as a means of seeking understanding and escaping emotional distress. However, they often suffer psychological impacts such as stress, anxiety, and depression due to limited access to mental health services, while government and organizational interventions are frequently ineffective.70 PagesSkripsi Sarjan

    Infusion Fluid Monitoring System Using Weight Sensors and Optocoupler Sensors Based on the Internet of Things (IoT)

    No full text
    Hospitals are in dire need of fluids such as IV fluids for every patient being treated, because these fluids play an important role in maintaining electrolyte balance, hydration, and supporting the patient's nutritional needs. Infusion is a method of administering fluids and drugs intravenously that is commonly used in various health facilities, especially for patients who are dehydrated, have lost blood, or need medication in certain doses. However, infusion monitoring is still carried out manually by medical personnel, which has several limitations. One of the main obstacles is the possibility of delaying the replacement of IV fluids, which can cause serious complications such as severe dehydration, electrolyte disorders, or even organ failure. Therefore, an automatic infusion monitoring system based on the Internet of Things (IoT) is needed that can help increase the effectiveness and efficiency in monitoring patient infusions in real time. In this study, a weight sensor is used to measure the volume of IV fluid, while the optocoupler sensor functions to detect the infusion drip rate. Data obtained from both sensors is then sent to the IoT platform, allowing medical personnel or nurses to monitor the patient's infusion condition remotely via the Virtuino application on a smartphone or computer. The test results show that this system is able to combine the volume and drip rate of IV fluids with high accuracy and provide timely notifications. With this system, monitoring of infusion fluids becomes more effective, the risk of delays in infusion replacement is reduced, and patient safety can be more assured.70 PagesSkripsi Sarjan

    Comparison of National Institute of Health Stroke Scale (NIHSS) Scores in Hemorrhagic Stroke Patients After Cerebrospinal Fluid Drainage Who Received Midazolam and Dexmedetomidine Sedation in the Intensive Care Unit of Adam Malik Hospital

    No full text
    Background: Stroke is a leading cause of morbidity and mortality worldwide. The National Institutes of Health Stroke Scale (NIHSS) is used to assess the neurological status of stroke patients. Cerebrospinal fluid (CSF) drainage is a critical intervention used to reduce intracranial pressure, and the choice of sedation and analgesia is crucial in ICU care. Midazolam provides sedative, anxiolytic, and anterograde amnesic effects, while dexmedetomidine has analgesic and anxiolytic properties with minimal effects on hemodynamics. Objective: To compare the NIHSS scores in hemorrhagic stroke patients after CSF drainage who received midazolam and dexmedetomidine sedation in the Intensive Care Unit of Adam Malik Hospital. Methods: This was a single-blind, randomized, controlled trial (RCT) that compared the NIHSS scores in hemorrhagic stroke patients after CSF drainage who received midazolam and dexmedetomidine sedation in the Intensive Care Unit of Adam Malik Hospital, with a sample size of 34 patients. Results: The sample characteristics showed a dominance of female patients in the 45-75 age range. Dexmedetomidine had a more stable hemodynamic profile. The post-extubation NIHSS scores showed more significant neurological improvement in the dexmedetomidine group, with statistically significant differences (p=0.006). The effectiveness of dexmedetomidine is thought to be related to its analgesic, sedative, and minimal depressive effects, making it a superior sedative choice in the ICU. Conclusion: Dexmedetomidine is more effective than midazolam in improving NIHSS scores in hemorrhagic stroke patients after CSF drainage in the ICU, with NIHSS scores showing more significant neurological improvement. This effectiveness is supported by the mechanism of action of dexmedetomidine as an alpha-2 adrenergic agonist152 PagesTesis Magiste

    No full text
    The intercity rice distribution system in North Sumatra, managed by Perum Bulog Medan, continues to face significant challenges in the form of high transportation costs and suboptimal delivery scheduling. This study aims to develop an optimization model for transportation scheduling to minimize distribution costs while still considering operational constraints such as vehicle capacity, travel time, and fleet availability. The proposed method applies a Genetic Algorithm (GA), using actual distribution data from Gatot Subroto and Mustafa. The model was implemented using Python programming language. Simulation results show that GA successfully reduced the total distribution cost from IDR 5.399.566.000 to IDR 3.359.393.000, achieving cost savings of approximately 38%. The optimized solution complies with all predefined operational constraints. A paired t- test analysis confirms that the proposed optimization model has a statistically significant impact on cost efficiency. Therefore, the use of Genetic Algorithm is proven to be effective in improving transportation scheduling and enhancing the efficiency of rice distribution logistics in North Sumatra.74 PagesSkripsi Sarjan
