Abstract

Tourette Syndrome (TS) is a neurological disorder affecting children under 18, with an estimated prevalence of over 150,000 cases annually in Indonesia and 1% globally. Misdiagnosis rates of 20-30% complicate effective management. TS involves involuntary, repetitive tics, ranging from sudden movements or sounds to aggressive behaviors, posing significant challenges for diagnosis and treatment. This study utilizes an expert system with a case-based reasoning (CBR) approach to improve TS diagnosis. Interviews with TS patients and specialists provided data on symptoms and diagnostic structures. A weighting mechanism and an accumulation formula were implemented to deliver accurate diagnostic outcomes and first aid suggestions, optimized for minimal computing resources without reliance on extensive datasets. Testing on 10 patients, under expert supervision, demonstrated the system's ability to accurately diagnose and classify TS. The system effectively simulates expert-level TS detection, offering precise diagnosis and recommendations, potentially enhancing early intervention and reducing diagnostic errors.

Abstract

Indonesia as a maritime country with a long coastline, holds significant potential in the marine and tourism sectors. However, these sectors are often disrupted by adverse weather conditions, particularly irregular wind speeds. Accurate wind speed forecasting is therefore essential for disaster mitigation. This study aims to forecast wind speed at Pantai Pangandaran using the Triple Exponential Smoothing (TES) method, which is more effective in handling data fluctuations with trend and seasonal patterns. The data used includes daily data from January 2014 to September 2024. The results show that the TES method provides highly accurate forecasts, with a low error rate evaluated through an RMSE of 0.51 and a MAPE of 17.85% for wind speed. These forecasts are expected to support disaster mitigation, enhance safety, and improve the efficiency of activities in coastal areas, particularly at Pantai Pangandaran, in facing adverse weather conditions.

Abstract

The Information Technology Certification Center (ITCC) currently uses a manual system for creating financial accountability reports. This process is time-consuming and often leads to errors. Furthermore, because the necessary data is not centralized, data loss is a frequent problem, hindering the creation of accurate reports. To address these issues, the author developed "lpjkita," an application designed to streamline and improve the financial reporting process. The development employed the spiral model, which integrates risk management with iterative development and prototyping, while incorporating the structured approach of the waterfall model. This methodology allows for rapid development and gradual software improvement. The resulting application, "lpjkita," enables faster creation of financial accountability reports at ITCC, minimizes errors, and improves data recording. In addition to these benefits, the application also contributes to environmental sustainability by reducing paper consumption at ITCC, thereby mitigating the impact of global warming.

Abstract

Ornamental fish care requires regular feeding, but the owner's busy schedule is often an obstacle. This study aims to design an Arduino-based automatic fish feeder, using an RTC (Real Time Clock) module for time scheduling and a servo motor to drive the feeding mechanism. This system is designed to ensure that feed is given at the right time without manual intervention. The prototype of this tool was tested in an ornamental fish pond and showed satisfactory results. This tool is able to provide feed accurately according to a predetermined schedule, and the servo motor functions well in controlling feed distribution. The use of RTC has proven effective in maintaining time accuracy, ensuring that fish eating patterns remain consistent. This tool is also efficient in energy use and provides convenience for ornamental fish owners, reducing the risk of missed or excessive feeding.

Abstract

Container throughput is an important indicator for measuring the efficiency of a kontainer terminal. Kontainers that enter and exit are those transported to and from the terminal, respectively. Kontainers are stacked in the kontainer yard before they leave the terminal. Handling these kontainers accounts for a major workload at the terminal. Therefore, accurate short-term forecasting of daily kontainer gate-in and Gate-Out at a kontainer terminal is crucial for operational planning. While most forecasts are made at the strategic level of overall kontainer throughput, this study focuses on the daily kontainer gate-in and Gate-Out quantities with a case study at the TPKNM Makassar Kontainer Terminal. The study results show that the Epoch for each training set and performance metrics for each feature are 10, 50, and 100. Based on this, the difference in prediction performance with different epoch sizes is quite significant. The larger the Epoch, the smaller the MSE level.

Abstract

One of the key success factors in the e-commerce industry is the increase in consumer engagement. High engagement has been proven to drive sales growth and customer loyalty. To achieve this goal, the application of gamification in marketing campaigns has been shown to have a significant impact on customer engagement in e-commerce. This study aims to optimize the selection of gamification types in pop-up campaigns to enhance consumer engagement on the XYZ e-commerce platform. The selection of the right type of gamification is crucial, but it is often influenced by subjectivity in assessment. To that end, this research uses the Analytic Hierarchy Process (AHP) method, which integrates historical data as a reference in filling alternatives based on criteria to reduce the subjectivity of the AHP method in determining the most effective type of gamification based on the criteria of Click-Through Rate (CTR), Conversion Rate (CR), and Impression. The research results show that the Memory Card type of gamification is the most effective type with the potential to increase consumer engagement. This approach is expected to serve as a reference for e-commerce platforms in designing more effective and data-driven gamification strategies.
