The Effect of Preoperative Maltodextrin Administration on the Incidence of Postoperative Nausea and Vomiting (PONV) in Cesarean Section Patients Undergoing Spinal Anesthesia
No full textBackground: Postoperative Nausea and Vomiting (PONV) is a common side effect
following anesthesia, including in patients undergoing Caesarean Section (CS) with
spinal anesthesia. PONV negatively affects patient comfort and postoperative
recovery. The preoperative administration of carbohydrate-rich fluids such as
maltodextrin has been recommended as part of the Enhanced Recovery After
Surgery (ERAS) protocol to reduce the incidence of PONV.
Objective: To evaluate the effect of preoperative maltodextrin administration on
the incidence of PONV in patients undergoing CS with spinal anesthesia.
Methods: This study was a randomized controlled trial with a single-blind design.
Subjects were elective CS patients with spinal anesthesia who met the inclusion
criteria. They were divided into two groups: the treatment group received 400 ml
of a drink containing 50 g of maltodextrin twice (8 and 4 hours before surgery),
while the control group followed standard preoperative fasting. PONV was assessed
at 6, 12, and 24 hours postoperatively using the ISS-PONV questionnaire.
Results: The maltodextrin group showed a significant reduction in ISS-PONV
scores compared to the control group at 6, 12, and 24 hours postoperatively
(p<0.001). The average PONV scores were lower in the group receiving
maltodextrin. No significant difference was found in blood glucose levels before
and after maltodextrin administration. There were also no significant differences in
demographic or baseline clinical parameters between the two groups.
Conclusion: Preoperative administration of maltodextrin is effective in reducing
postoperative nausea and vomiting in CS patients undergoing spinal anesthesia.94 PagesTesis Magiste

Analysis of The Effect of Sunlight Intensity on Battery Charging Efficiency From Solar Panels Based on The Internet of Things (IoT)
No full textThis study aims to analyze the effect of sunlight intensity on the efficiency of battery charging using a solar panel monitored in real-time through an Internet of Things (IoT)-based system. The results show a proportional relationship between light intensity and charging efficiency. Higher light intensities (above 40,000 lux) generate stable current and voltage, leading to faster and more efficient battery charging. Conversely, at lower intensities (below 10,000 lux), the charging process slows down or even stops. The monitoring system was built using an ESP8266 microcontroller, a BH1750 light sensor, and an OLED display as a local output, all integrated and functioning properly. The system is connected to the Blynk IoT platform, enabling remote data monitoring in the form of digital values and interactive graphs. This facilitates performance analysis of the solar panel under various environmental conditions. Overall, the system successfully meets the research objectives: analyzing the relationship between light intensity and charging efficiency, developing an IoT-based monitoring system, and presenting real-time data visualization for practical and informative analysis.54 PagesKertas Karya Diplom
Implementation Of Rank-Based Ant System On Android-Based Time Management Application
No full textThe Directorate of Digitalization and System Integration (Ditgrasi) of Universitas Sumatera Utara faces significant challenges in manually scheduling website training activities, which are complex, time-consuming, and prone to schedule conflicts. This research aims to develop an Android-based time management application that implements the Rank-based Ant System (RankedAS) algorithm to provide an automated scheduling solution for these issues within the Ditgrasi environment. The application's core scheduling function was tested using the Black Box Testing method through two complex scenarios. The results showed that the application successfully generated an optimal and entirely conflict-free schedule in the first scenario, which involved 20 training activities and 2 meeting schedules as constraints. In the second, more complex scenario with 30 training activities and 5 meeting schedules, the system's performance was deemed quite satisfactory despite two identified conflict case related to human resource allocation, in which a programmer was scheduled in two different rooms simultaneously. However, most schedules were successfully optimized according to the existing constraints. Furthermore, algorithm testing was performed to prove its accuracy by comparing the application's results with manual calculations in a simple scenario. In the first iteration, two solutions generated by the ants scored 100, with the first-ranked solution's pheromone updated by 200 and the second-ranked by 100. In the second iteration, both solutions also scored 100, and the pheromones were updated to 290 and 200 for the first rank and 280 for the second rank, matching the manual calculation. The results indicate that the application can produce accurate calculations. This research demonstrates that the developed automated scheduling application based on the Rank-based Ant System functions, as expected, shows great potential for improving efficiency and reducing the workload at Ditgrasi USU. Nevertheless, the application requires further optimization to handle constraints for high complexity and density scheduling scenarios.93 PagesSkripsi Sarjan
Comparative Analysis of The Application of Fuzzy Logic Using The Sugeno and Tsukamoto Method in Weather Forecasting in Medan City
No full textThis study aims to compare the Sugeno and Tsukamoto methods applied in weather forecasting using Fuzzy Logic. The input variables include air temperature, humidity, sunlight duration, and wind speed, while the output variable comprises weather categories: no rain, light rain, moderate rain, and heavy rain. The data used are secondary data obtained from the Meteorology, Climatology, and Geophysics Agency (BMKG) Region I Medan for October 2024. The Sugeno and Tsukamoto methods were implemented to forecast the weather in Medan City. The performance of both methods was evaluated using the sign test with a binomial distribution against actual weather data. The results showed that the Sugeno method produced 7 positive signs and 2 negative signs (p-value = 0.0898), while the Tsukamoto method produced 5 positive signs and 2 negative signs (p-value = 0.2264). Since both p-values are greater than the significance level of 0.05, it can be concluded that there is no statistically significant difference between the forecast results of the two methods and the actual data. However, the smaller p-value of the Sugeno method indicates a closer alignment with the actual data, suggesting that this method has better accuracy than the Tsukamoto method. A linear regression model was used to predict the input variable values for the 32nd and 33rd data entries. Both methods forecasted moderate rain for these entries, while the actual data showed moderate rain and heavy rain. This indicates that both methods were able to provide forecasts that closely matched actual weather conditions.61 PagesSkripsi Sarjan
