One of the most widely used methods is the You Only Look Once (YOLO) algorithm, which is capable of real-time object detection with a high degree of accuracy. This study aims to analyze the performance comparison of two variants of the YOLOv8 model, namely YOLOv8n and YOLOv8s, in detecting objects using evaluation metrics and confidence scores. The dataset used consists of 5000 images, which are divided into training data (70%), validation data (20%), and testing data (10%). Model performance evaluation is carried out using several object detection metrics, namely precision, recall, and mean Average Precision (mAP), as well as additional analysis in the form of computation time and confidence scores to assess the stability of the model's predictions. The results show that the YOLOv8n model achieved a precision value of 0.9313, while the YOLOv8s model achieved a recall value of 0.8415 and a mean Average Precision (mAP0.5) of 0.9055, which is slightly higher than YOLOv8n with a mAP0.5 value of 0.9009. In terms of computational efficiency, YOLOv8n has a faster training time of around 2670 seconds, compared to YOLOv8s which takes around 4477 seconds. In addition, the YOLOv8s model shows a higher confidence score, which indicates a better level of prediction confidence in detecting objects. Based on these results, it can be concluded that YOLOv8n is superior in computational efficiency, while YOLOv8s provides more stable and accurate detection performance.

Waste incineration can serve as a solution, but it has the potential to cause undesirable consequences if not properly supervised; therefore, a monitoring system capable of tracking the waste incineration process in real-time is necessary. With the rapid advancement of technology, wireless technology can be utilized to address this issue. However, most wireless technologies still rely on internet networks, making them less effective in areas with limited internet connectivity.

Delayed diagnosis remains a primary challenge, as nearly half of those affected are unaware of their condition in the early stages, thereby increasing the risk of fatal complications. Data mining approaches using classification algorithms have been widely utilized for early screening. However, the development of medical record models is often hindered by imbalanced data, which causes models to be biased toward the majority class and reduces detection sensitivity for the minority class (patients with diabetes). Furthermore, there is a lack of research integrating these predictive models into responsive application interfaces for end-users. Consequently, this study implements Random Forest optimized with the SMOTE (Synthetic Minority Over-sampling Technique) into a web-based application to serve as a practical early detection tool. Random Forest was selected for its ability to handle complex data and reduce the risk of overfitting. The research stages include data preprocessing, balancing training data using SMOTE, model parameter adjustment through hyperparameter tuning with Grid Search, and the development of a client-server architecture using AstroJS and Flask. The evaluation results demonstrate that the use of SMOTE significantly improves the model's ability to identify the minority class. The model achieved a Recall of 75.0% and an overall accuracy of 95.8%, effectively minimizing False Negative errors.

The literature indicates that conventional Electronic Health Record (EHR) systems remain vulnerable to data breaches, information manipulation, and system failures due to their centralized architecture. This review examines the development of blockchain technology as a potential solution for modern healthcare data management. The study employs a systematic literature review using the Publish or Perish approach, with Google Scholar as the data source to identify relevant scientific articles, which were subsequently screened based on predefined inclusion and exclusion criteria and analyzed qualitatively. Owing to its characteristics of decentralization, immutability, strong cryptography, and the use of smart contracts for access control, blockchain offers significant improvements in medical data security, transparency, and interoperability. Its applications have been reported in EHR systems, telemedicine, pharmaceutical supply chains, medical imaging, and clinical trial data management. Nevertheless, several limitations continue to hinder widespread adoption, including scalability issues, computational overhead, integration complexity with legacy systems, the transparency–privacy trade-off, and regulatory challenges such as compliance with data protection laws and international standards. Future research trends point toward the integration of blockchain with artificial intelligence, the Internet of Medical Things (IoMT), and federated learning, as well as the development of lightweight blockchain solutions for resource-constrained environments. Overall, blockchain demonstrates considerable potential to strengthen the security and reliability of healthcare information systems; however, its implementation requires a gradual, standardized, and regulation-compliant approach.</p> <p> </p>2025-04-28T00:00:00+07:00Copyright (c) 2026 Jurnal CoSciTech (Computer Science and Information Technology)https://ejurnal.umri.ac.id/index.php/coscitech/article/view/10988Tinjauan Penerapan CNN dan YOLO Pada Pengolahan Citra Agraria Medis Insdutri Cerdas2026-04-04T20:49:14+07:00Robby Saputra14240031@nusamandiri.ac.idYan Riantoyan001@gmail.comMuhammad Romadhona Kusumam.romadhona.kusuma@darunnajah.ac.id<p style="font-weight: 400;"><em>The Rapid growth of Artificial Intelligence </em>(AI), <em>particularly Deep Learning, is driving significant transformations in digital image processing in the argricultural, medical, and smart industrial sectors.

Determining calorie requirements is not simple because it must take into account factors such as age, gender, <br>body mass index (BMI), and physical activity level. This study aims to develop a Mamdani fuzzy logic-based expert system to <br>provide recommendations for daily calorie requirements for people with type 2 diabetes. The system process is carried out <br>through the stages of fuzzification, inference, aggregation, and defuzzification using the centroid method. Testing was conducted <br>using 20 type 2 diabetes patient data with input variables of age, height, weight, gender, and physical activity. The testing <br>methods used were accuracy and black-box. Accuracy testing was performed by comparing the system's results with manual <br>calculations based on medical standards, while black-box testing ensured that the system functioned as designed. The results <br>showed that the system had an accuracy rate of 80%, making it sufficiently valid and usable as a tool for recommending daily <br>calorie intake to support diet management for type 2 diabetes patients.</p>2026-04-28T00:00:00+07:00Copyright (c) 2026 Jurnal CoSciTech (Computer Science and Information Technology)https://ejurnal.umri.ac.id/index.php/coscitech/article/view/10955Usability Testing Analysis of Digital Transportation Applications Using the System Usability Scale (SUS)2026-04-27T10:06:46+07:00Insan Rezqy Aghniyainsanrezqyaghniya@gmail.co.idWulani Daripenulis.dua@xmail.ac.id<p><em>The development of information technology in the transportation sector has transformed the way people carry out their mobility activities, particularly through the use of digital transportation applications. Although these applications offer various conveniences, several issues are still encountered in their practical use, which may affect user comfort and satisfaction. Therefore, usability becomes a crucial aspect in evaluating the quality and performance of digital transportation applications. This study applies the System Usability Scale (SUS) method using a Likert scale in the research questionnaire to analyze usability. Primary data were collected through observation, interviews, literature review, and the distribution of SUS questionnaires to users of digital transportation applications in the DKI Jakarta area aged between 17 and 45 years. The results of the analysis show an average score of 73.4, which falls into the acceptable category and indicates that the application is well accepted by users. This research contributes an evaluation of the usability level of digital transportation applications, which can serve as a basis for system improvement recommendations, particularly in terms of usage flow, user interface, and user feedback, as well as a reference for future studies related to user experience development</em></p>2026-04-28T00:00:00+07:00Copyright (c) 2026 Jurnal CoSciTech (Computer Science and Information Technology)https://ejurnal.umri.ac.id/index.php/coscitech/article/view/10598Sistem Pakar Analisis Love Language untuk Menilai Kualitas Komunikasi Pasangan Milenial Menggunakan Forward Chaining dan Certainty Factor2025-12-20T12:01:13+07:00Deosa Putra Caniagodeozaofficial@gmail.comVincent Tan2322008@iteba.ac.idSindy Silvia Soarta Pakpahan2322011@iteba.ac.idSalsabila Adine Susyantika2322035@iteba.ac.idM Rachmat Sulthonytony.rachmat@gmail.comMaria Yosefina Meinadia Sekar Kinanti Aswirawanariayosefinameinadia.ska@upnyk.ac.id<p><em>This research aims to analyze the influence of love language on communication quality among millennial couples in Indonesia. Millennials, who are highly immersed in digital interaction, tend to communicate quickly and text-based, making romantic interactions dynamic yet prone to misunderstanding. A quantitative survey was conducted involving 180 respondents aged 22–35 who had been in a relationship for at least one year. A Likert-scale questionnaire measured preferences across the five love language categories—Words of Affirmation, Quality Time, Acts of Service, Physical Touch, and Receiving Gifts, as well as communication quality indicators including openness, clarity, trust, and emotional intimacy.</em></p> <p><em>Findings indicate that all five love languages significantly affect communication quality, each with varying levels of influence. Quality Time emerged as the most dominant category with an estimated tendency of <strong>92–96%</strong>, followed by Words of Affirmation with a dominance level above <strong>85%</strong>. These results suggest that understanding and adapting to one’s partner’s love language can serve as an effective communication strategy to increase emotional closeness, reduce conflict, and strengthen relationship harmony among millennial couples.</em></p>2026-04-28T00:00:00+07:00Copyright (c) 2026 Jurnal CoSciTech (Computer Science and Information Technology)https://ejurnal.umri.ac.id/index.php/coscitech/article/view/11335Klasifikasi Penyakit Daun Singkong Menggunakan Arsitektur Efficientnet Berbasis Transfer Learning2026-05-12T18:00:18+07:00Syahrul Ramadanisyahrulgeal363@gmail.comMuh. Rasyid Ridharasyid4sky@gmail.comSamsudin Samsudinsamsudinsadek@gmail.com<p><em>Cassava (Manihot esculenta) is a strategic agricultural commodity whose productivity is frequently threatened by leaf diseases such as bacterial blight, brown streak, green mottle, and mosaic disease. Manual identification by humans tends to be subjective, time-consuming, and prone to error. This study aims to develop an automatic and intelligent Cassava leaf disease classification system based on Deep Learning that is both accurate and efficient. To overcome the computational burden of conventional models and address real-world data challenges, such as class imbalance and lighting variations, this research proposes the use of the EfficientNet architecture combined with the Transfer Learning method. The model utilizes pre-trained weights from ImageNet to accelerate convergence and optimize visual feature extraction. Experimental results on the Cassava leaf image dataset show that the proposed model successfully achieved an accuracy rate of 81%. These findings demonstrate that the EfficientNet approach provides objective predictions with high computational efficiency. This research has significant potential for implementation in portable devices as an early detection tool for farmers, supporting rapid mitigation actions and maintaining global food security stability</em></p>2026-04-28T00:00:00+07:00Copyright (c) 2026 Jurnal CoSciTech (Computer Science and Information Technology)https://ejurnal.umri.ac.id/index.php/coscitech/article/view/11058Recommendation for Determining Mustahik Priority at BAZNAS Pontianak Using the AHP–TOPSIS Method2026-04-04T20:42:16+07:00Wahyu wahyuwwwahyu.march@gmail.comAlda Cendekia Siregaralda.siregar@unmuhpnk.ac.idMenur Wahyu Pangestikamenur.wahyu@unmuhpnk.ac.id<p><em><span dir="auto" style="vertical-align: inherit;"><span dir="auto" style="vertical-align: inherit;">Prioritas mustahik menimbulkan tantangan signifikan dalam administrasi zakat, karena prosesnya sering dipengaruhi oleh faktor subjektif dan kurangnya efisiensi.
