Abstract

Stunting is a very important public health problem because it can have a big impact on a generation. One of them is the risk factor of nutrition and food intake that is not fulfilled in toddlers. For this reason, a system is needed to find out earlier the growth and development period of toddlers so that stunting symptoms can be detected as early as possible so that it can provide solutions to overcome these problems. The proposer's linkage from previous research in 2018 focusing on elementary school children and toddlers is included in the research roadmap from 2018-2028. For this reason, an early detection system is designed with the stages of designing a height measuring device, toddler weight using an ultrasonic sensor and information detecting stunting is displayed on an LCD screen integrated with Arduino. The software development method uses prototypes and testing for accuracy in toddler height using Mean Absolute Percentage Error (MAPE) with a value of 2% and from the results of testing 10 toddlers, there were 3 children in the stunted category.

Abstract

The success of students in core computer science courses such as Algorithms and Programming is a critical factor in their academic journey, as it reflects both mastery of fundamental concepts and readiness for more advanced studies. Academic performance in this course is not only shaped by grades but also by behavioral and psychological attributes that influence learning outcomes. This study investigates the influence of academic performance on graduation in Algorithms and Programming using a predictive machine learning approach. The dataset includes 106 student records encompassing academic variables (attendance, average grades, assignment scores), psychological factors (motivation, anxiety toward examinations), and behavioral indicators (discussion participation, AI tool usage, online learning activities). The research adopts the SEMMA methodology, consisting of sampling, exploration, modification, modeling, and assessment. Several classification algorithms were tested, and Random Forest was selected as the primary model due to its strong performance and interpretability. The results indicate that academic achievement variables, particularly average grades and attendance, significantly influence graduation. Additionally, non-academic factors such as motivation, discussion activity, and exam anxiety contribute to predictive outcomes. The model achieved an accuracy of around 91% and an AUC score of 0.93, confirming its reliability in distinguishing between students who passed and those who did not. These findings highlight that academic performance influences success in algorithm and programming courses.

Abstract

User Interface (UI) design plays a crucial role in enhancing user interaction, efficiency, and satisfaction in digital information systems. This study aims to design and evaluate the login module of the membership information system for Kelompok Seni Sigertengah using the User Centered Design (UCD) approach. The research methodology follows the UCD framework based on ISO 9241-210, which includes understanding the usage context, identifying user requirements, designing prototypes, and conducting evaluations through usability testing. Data were collected through observation, interviews, documentation studies, and prototype testing involving five representative users. The results show that the questionnaire scores ranged from 4.0 to 4.8, with an overall score of 4.43 out of 5, categorized as “Very Good.” Qualitative findings further indicate that the UI is easy to use, reflects local artistic identity, and improves both user comfort and system access efficiency. Therefore, the application of UCD has proven effective in producing a user interface design that meets user needs and is feasible to be implemented as a development model for UCD-based UI in arts and culture MSMEs.

Abstract

Deep Learning is a popular Machine Learning algorithm that is widely used in many areas in current daily life. Its robust performance and ready-to-use frameworks and architectures enables many people to develop various Deep Learning-based software or systems to support human tasks and activities. Traffic monitoring is one area that utilizes Deep Learning for several purposes. By using cameras installed in some spots on the roads, many tasks such as vehicle counting, vehicle identification, traffic violation monitoring, vehicle speed monitoring, etc. can be realized. In this paper, we discuss a Deep Learning implementation to create a vehicle counting system without having to track the vehicles movements. To enhance the system performance and to reduce time in deploying Deep Learning architecture, hence pretrained model of YOLOv5 is used in this research due to its good performance and moderate computational time in object detection. This research aims to create a simple vehicle counting system to help human in classify and counting the vehicles that cross the street. The counting is based on four types of vehicles, i.e. car, motorcycle, bus, and truck, while previous research counts the car only. As the result, our proposed system capable to count the vehicles crossing the road based on video captured by camera with the highest accuracy of 97.72%

Abstract

Breast cancer is one of the deadliest diseases, especially for women. Early diagnosis of breast lesions and differentiation of malignant nodules from benign nodules and normal nodules are important for breast cancer prognosis. In diagnosing this disease, one radiological method, namely medical image analysis using ultrasonography, can be used to determine early diagnosis of breast cancer. Breast cancer ultrasound images have several characteristics, such as color, shape, size, and texture, which make segmentation difficult due to object accumulation. This study implements a Convolutional Neural Network classification algorithm and modified watershed segmentation to separate nodules or tumors in breast cancer. From the segmentation performance test with Watershed Transform, the average ZSI index was 40% for malignant images and 60% for benign images. The results of the VGG architecture for classification modeling showed 47% for watershed segmentation and 80% without watershed segmentation.

Abstract

This study aims to develop an automated deep learning-based system to monitor compliance with the use of Personal Protective Equipment (PPE) in the manufacturing industry. Manual monitoring, which has been carried out so far, is considered inefficient and prone to error. This system compares three approaches: the YOLOv8 model, SSD Mobile Net, and a hybrid method that combines the two. The dataset consists of 700 images covering eight classes related to PPE use. The results show that the hybrid method performs best with: 1. Accuracy: 95.1%, 2. Precision: 98.7%, 3. Recall: 97.2%, and F1-Score: 94.5%. Although its detection speed (18 FPS) is slightly lower than SSD (29 FPS), its detection quality is superior. The system has been implemented in a web application that can run in real-time using a webcam, equipped with an alarm and “SAFE” or “NO SAFE” notifications. This system is expected to be an accurate and efficient digital solution to improve work safety.

Abstract

Agricultural development requires reliable methods for measurable soil condition monitoring to support crop growth. Soil moisture and soil pH are critical parameters that significantly affect plant development. Manual observation of these parameters is inefficient and often produces inconsistent data. This study designed a smart drip irrigation system integrating soil moisture and soil pH sensors with RS485 communication using the MAX485 module. Arduino Nano was applied as the sensor node for data acquisition, and ESP32 was used as the master controller for decision-making in irrigation and fertilization. System validation employed Lavios VT-05 as the reference instrument. Experimental results showed that soil moisture sensors provided consistent readings with minimal deviation across different conditions, while soil pH sensors maintained high accuracy compared to standard buffer solutions. RS485 communication was tested up to 7 meters and demonstrated stable performance. These findings confirm that the system is capable of accurate soil monitoring and reliable communication for smart drip irrigation applications.

Abstract

The rapid development of information technology demands companies to have a network infrastructure that is not only fast but also secure and efficient. PT. XYZ, as a company engaged in distribution and customer service, faces challenges in managing increasing data traffic while maintaining the stability and security of its internal network. One strategic solution to address this issue is the implementation of a proxy server. A proxy server functions as an intermediary between users and the internet, enabling it to filter data requests, store cache, and restrict access to unwanted content. Thus, the implementation of a proxy server can improve bandwidth efficiency, accelerate access to frequently used websites, and strengthen network security systems through traffic monitoring and restriction. This research aims to implement and evaluate the effectiveness of using a proxy server within PT. XYZ’s environment. The evaluation results show that the use of a proxy server can enhance network efficiency and provide better protection against cyber threats. With a more controlled and secure system, the company can run its operations more optimally and sustainably.
