Abstract

Heart disease is a medical condition affecting the cardiovascular system, disrupting blood circulation and reducing cardiac function efficiency, which can lead to severe health complications. Early diagnosis of heart disease has become increasingly crucial as delayed detection can significantly impact patient outcomes and survival rates. While numerous studies have explored various approaches for heart disease classification, challenges related to data imbalance and improper parameter settings remain persistent issues that affect model performance. This research evaluated the effectiveness of combining TabNet with SMOTE and optuna hyperparameter optimization for heart disease classification. We conducted four experimental scenarios using a heart disease dataset with 303 instances: baseline TabNet, baseline TabNet with SMOTE, TabNet with Optuna, and TabNet with both SMOTE and Optuna. Results demonstrated that applying SMOTE alone to TabNet decreased model performance (accuracy from 85.24% to 77.04%, AUC from 0.89 to 0.83). However, when combining SMOTE with Optuna hyperparameter optimization, we achieved optimal performance with 90.16% accuracy, 93.33% precision, 87.50% recall, 90.32% F1-score, and 0.93 AUC. This represented a significant improvement over other configurations and several previous classification approaches. The integration of SMOTE with Optuna optimization  provided an effective framework for heart disease classification that outperformed traditional methods particularly in discriminative capability as evidenced by the superior AUC score.

Abstract

The use of Information and Communication Technology (ICT) has an important role in increasing the competitiveness of micro, small, and medium enterprises (MSMEs), including Nurisfood, a cooking spice producer in Sleman, Yogyakarta. Despite experiencing rapid growth, Nurisfood still faces several major challenges, such as limitations in accounting systems and digital marketing strategies. This Community Service Activity aims to overcome these problems with web-based Accounting Information Systems (AIS) and Cost Accounting and COGS training and digital marketing strategy training. With this intervention, it is hoped that Nurisfood can improve operational efficiency, expand the market, and increase turnover, so that it can compete in the industrial era 4.0. The approach used is through training activities carried out in four sessions for Accounting Information Systems (AIS) and Cost Accounting including the delivery of concepts and materials, discussions, training in calculating Cost of Goods Sold (COGS), and evaluation while digital marketing training includes digital marketing socialization and product photography training using smartphones. The results obtained are in the form of increased knowledge and skills of partners in managing businesses, as well as the application of more effective technology in daily operational activities in the use of AIS, Cost Accounting and quality product photos.

Abstract

Cerita rakyat lokal kini mulai terpinggirkan oleh kisah-kisah luar negeri, padahal nilai budaya dan religius di dalamnya sangat penting untuk dilestarikan. Salah satu kisah lokal yang kaya akan nilai adalah “Karomah Syekh Jangkung” dari Landoh, Pati, Jawa Tengah. Untuk mengangkat kembali cerita ini, dikembangkan film animasi dua dimensi (2D) menggunakan teknik cel animation sebagai media informasi yang bermuatan pendidikan. Penelitian dilakukan melalui tahapan pra-produksi, produksi, hingga pasca-produksi, dengan pemanfaatan perangkat lunak seperti Adobe Animate, Photoshop, After Effects, dan Premiere Pro. Evaluasi dilakukan melalui pengujian alpha oleh pengurus makam serta pengujian beta oleh wisatawan dan mahasiswa. Hasil menunjukkan animasi ini memenuhi aspek fungsional, visual, dan informatif dengan penilaian sangat baik. Indeks kualitas animasi mencapai 90%, pewarnaan, backsound, dan teknik cel masing-masing 80%, serta kualitas audio 77%. Dengan hasil tersebut, animasi ini dinilai layak sebagai media edukasi dan promosi budaya yang efektif, serta berpotensi meningkatkan ketertarikan generasi muda dan wisatawan terhadap warisan budaya lokal.

Abstract

Robusta coffee is a coffee variety that has unique characteristics, a strong taste and a different level of bitterness from Arabica coffee because Robusta coffee contains lower sugar and 2.2% more caffeine than Arabica coffee so that Robusta coffee production is quite helpful for the economy. several coffee producing countries in the world. The quality and productivity of coffee plants can decrease due to several factors such as pests and disease. However, the limitations of experts regarding coffee plant diseases are a factor and obstacle. The aim of this research is to create an expert-based intelligent system to identify pests and diseases in robusta coffee plants. The method that will be applied is Dempster Shafer. Data on disease names amounted to 13 and data on symptoms amounted to 27. The final result was that Robusta coffee plants were tested for expertise on the system with an average accuracy of diagnosis results of 94% from 13 test cases on pests and diseases of coffee plants, so it can be concluded that the system Experts can diagnose coffee plant pests and diseases very well using the Dempster Shafer method

Abstract

To maintain and enhance the quality of the Mobile Food Intake Control Application for Outpatients in the Hospital, usability testing must be conducted using the System Usability Scale (SUS). This research aims to evaluate usability and analyze user-friendliness for further action by the Hospital. The respondents consist of 138 outpatient patients. Testing is carried out by requesting respondents to perform scenarios on the Mobile Food Intake Control Application, observed directly by the examiner. Subsequently, respondents fill out a questionnaire containing ten statements with Likert scale responses. The average SUS score of 87.0471 indicates excellent acceptance of the application, and the user rating suggests that the application meets user expectations sufficiently. However, user speed in using the application and focusing on its features are still considered normal, and the error rate falls within acceptable limits.

Abstract

This research aimed to develop and evaluate an IoT-based electric safety buoy equipped with an autonomous navigation system to support Search and Rescue (SAR) operations in coastal environments. The system integrates dual‐thruster propulsion, GPS and Inertial Measurement Unit (IMU) sensors, IoT telemetry, and a Return-to-Home (RTH) mechanism, enabling both manual and autonomous operation modes. Prototype testing was conducted in a controlled aquatic environment under light wave conditions (10–25 cm) and mild surface currents (0.18–0.32 m/s), with calm weather and unobstructed line-of-sight communication. The buoy was evaluated in both unloaded and 2 kg payload conditions, traveling at an average speed of 1.25–1.35 m/s across test sessions lasting 12–18 minutes. Three predefined GPS waypoints were used to assess navigation accuracy, motion stability, RTH reliability, and telemetry performance. Results show that the autonomous mode achieved a mean positioning error of 1.12 m, a cross-track deviation of 0.35 m, and a waypoint success rate of 96%, outperforming manual navigation by 52%. The RTH function maintained a success rate of 100% under low-battery conditions and 92% during communication loss, while IoT telemetry remained stable up to 200 meters with less than 1% packet loss. These findings confirm that integrating IoT-based telemetry with adaptive autonomous navigation enhances rescue mission efficiency and operational safety, while indicating the need for further validation under more challenging open-sea conditions.

Abstract

Ruang tertutup merupakan tempat yang memiliki potensi lebih tinggi dalam penyebaran virus COVID-19. Hal ini dikarenakan virus COVID-19 dapat terbawa udara. Ruang tertutup membuat udara semakin lama di ruang tersebut. Terlebih ruang tertutup sangat banyak digunakan untuk beraktivitas seperti rumah, sekolah, mall, kantor, tempat ibadah, dll. Sehingga untuk ruang tertutup harus mendapat perhatian serius untuk dapat menghindari penyebaran virus. AirDisinfeX adalah alat berbasis IoT dengan dilengkapi sinar UVC yang dapat membunuh virus termasuk virus COVID-19. Alat ini dapat dikendalikan dari jarak jauh secara manual atau timer. Sehingga alat bisa diaktifkan terlebih dahulu sebelum ruang tertutup digunakan. Penelitian ini juga menggunakan mikrokontroler ESP32 dalam mendukung pengembangan alat AirDisinfeX berbasis IoT. Hasil penelitian ini dengan akurasi sistem IoT AirDisinfeX sebesar 96,10% dan waktu respon rata-rata 5,32 detik
