Abstract

Pemanfaatan teknologi dalam pembelajaran sangat penting untuk meningkatkan pemahaman dan keterampilan siswa, khususnya dalam pemrograman mikrokontroler berbasis Arduino. Pelatihan ini dilakukan di SMA N 1 Tahunan dengan menggunakan simulator online Wokwi sebagai alternatif pembelajaran praktis. Metode yang digunakan mencakup pemaparan teori, demonstrasi, diskusi interaktif, dan praktik langsung. Sebelum pelatihan, dilakukan pre-test untuk mengukur pemahaman awal siswa terkait konsep dasar Arduino, dengan rata-rata nilai pre-test sebesar 68,0. Setelah pelatihan, nilai rata-rata post-test meningkat menjadi 88,0, menunjukkan selisih rata-rata sebesar 20,0 poin. Hasil pelatihan menunjukkan peningkatan signifikan pada sebagian besar siswa. Contohnya, Siswa 21 yang awalnya memiliki nilai pre-test 20 berhasil mencapai nilai post-test 90, mencerminkan peningkatan pemahaman yang luar biasa. Namun, terdapat siswa seperti Siswa 4 yang menunjukkan peningkatan terbatas, dari nilai pre-test 30 menjadi 70, menunjukkan perlunya pendekatan yang lebih personal. Pelatihan menggunakan Wokwi terbukti efektif dalam meningkatkan pemahaman siswa terhadap pemrograman Arduino sekaligus mengatasi keterbatasan fasilitas laboratorium. Kegiatan ini juga berhasil meningkatkan minat siswa terhadap teknologi dan penerapannya dalam kehidupan sehari-hari. Untuk hasil yang lebih optimal, disarankan adanya bimbingan tambahan bagi siswa tertentu dan penambahan sesi praktik menggunakan perangkat Arduino fisik.

Abstract

This study investigates public sentiment on the Mobile JKN application using Logistic Regression enhanced with SMOTE-based statistical feature selection. Unlike prior works that relied solely on conventional feature combinations such as TF-IDF or Word2Vec, this research performs a comparative evaluation of three statistical feature selection techniques: Recursive Feature Elimination (RFE), Chi-Square, and Mutual Information, under both TF-IDF and Word2Vec representations in a low-resource Indonesian language setting. The dataset consists of 2,382 user reviews from the Google Play Store, balanced using SMOTE to mitigate class imbalance. The best configuration, TF-IDF combined with Mutual Information, achieved an accuracy of 73.38% and an F1-score of 50%, indicating a moderate yet consistent performance. A confusion matrix-based error analysis revealed that most misclassifications occurred between neutral and negative classes due to semantic overlap. The relatively low F1-score highlights challenges in sentiment separability, while the superior performance of Mutual Information demonstrates its ability to capture discriminative linguistic features. The superior performance of Mutual Information is attributed to its ability to capture non-linear dependencies between features and sentiment labels, yielding richer discriminative information compared to Chi-Square or RFE. This research establishes a comparative methodological framework that integrates feature selection and data balancing techniques, providing interpretable sentiment classification insights for under-resourced language settings.

Abstract

In the retail industry, fast and responsive service is essential for maintaining customer satisfaction and loyalty. A key challenge faced by store owners is delayed responses to customer arrivals, leading to dissatisfaction and potential lost sales. This project develops an automatic notification system using Speech-to-Text technology and a Telegram bot to detect voice keywords and send real-time notifications to store owners. The system was developed using the prototype methodology, allowing for iterative testing and refinement to ensure it met user needs and functional requirements. It integrates the Deepgram API for accurate speech transcription, the Telegram Bot API for notifications, and a web interface for managing keywords and monitoring system status. To enhance efficiency, a Voice Activity Detection (VAD) module was added, ensuring that only human speech is processed, thereby reducing unnecessary processing. Experimental results showed that the system achieved 100% accuracy in quiet environments and 80% in noisy conditions. The system's response time was also impressive, with an average time of 3.72 seconds in quiet conditions and 3.8 seconds in noisy environments. Word Error Rate (WER) and Character Error Rate (CER) evaluations indicated perfect accuracy in quiet conditions (WER 0%, CER 0%) and slight errors in noisy conditions (WER 13.33%, CER 12.5%). Overall, the system effectively improved service speed and responsiveness, offering store owners a valuable tool for enhancing customer experience in retail environments.

Abstract

The process of prioritizing the development of an industrial area's site is a matter that necessitates a mature approach. The establishment of an industrial region has significant social implications for the surrounding locality. However, it is also necessary to take into account the availability of variables that facilitate the functioning of such an industrial zone. The goal of the study "A Comparative Analysis of Multi-Criteria Decision Making Methods (MCDM) for Determining the Priority of Industrial Area Location Development" is to compare and contrast different MCDM methods in the context of deciding which industrial area locations should be developed first. A case study was undertaken, examining various possible industrial sites for future development. Multiple approaches, namely MOORA, WASPAS, ARAS, COPRAS, and AHP, are employed to ascertain the prioritization of industrial area development locations. This study presents a comparative analysis of each approach by using the Spearman Rank correlation and utilizing the factual data obtained from the Department of Capital Plantation and Integrated One Door Services (DPMPTSP). The external research is anticipated to involve a comprehensive review of the literature on the efficacy of Multiple Criteria Decision Making (MCDM) methods. This research has the potential to assist both governmental bodies and private entities in establishing priorities for the development of industrial areas, taking into account prevailing circumstances and conditions while also considering various significant factors and criteria.

Abstract

This study aims to identify the most effective social media platforms for digital marketing. The use of social media for promotion continues to grow, yet many businesses still struggle to determine which platforms have the greatest impact. Therefore, this study compares the performance of various machine learning platforms to predict the best platform. The algorithms used are Gradient Boosting Regressor, XGBoost Regressor, Convolutional Neural Network (CNN), and Support Vector Regression (SVR) to estimate digital conversion potential based on user reviews, ad reach, and content trend patterns. A Knowledge Discovery in Databases (KDD) workflow is used to identify the most important key factors. This process includes data preprocessing, TF-IDF feature extraction, sentiment analysis, feature engineering, and feature elimination (RFE). The results showed that the CNN algorithm excelled in prediction, with the highest R² score of 0.74 and the lowest RMSE of 14.78. CNN predictions showed YouTube topping the list in terms of conversion potential, followed by Facebook and TikTok. These results highlight the higher promotional effectiveness of video-based platforms and the importance of machine learning in digital marketing decision-making. However, this study is limited by its reliance on static user review and ad reach data, which may not fully capture the dynamic changes of social media platforms.

Abstract

The rapid growth of motorized vehicles in Indonesia, unmatched by proportional expansion in road infrastructure, has intensified pressure on the national transportation system. This study examines the application of a Long Short-Term Memory (LSTM) model to analyze and forecast the national traffic load ratio, defined as the ratio of total motorized vehicles to total road length. Annual aggregate data from the Indonesian Central Bureau of Statistics (BPS) for the period 2016–2023 were used in the analysis. The results indicate that the model achieved a strong fit on the training data, with RMSE = 0.3652 and MAE = 0.3617, but performed substantially worse on the test data, with RMSE = 1.7585 and MAE = 1.7585. This discrepancy suggests overfitting, largely attributable to the extremely limited sample size. As such, the findings should be interpreted as exploratory rather than as evidence of reliable forecasting performance. Despite these limitations, the model projects a continued upward trend in national infrastructure pressure over the next five years. These findings provide an initial data-driven indication that transportation infrastructure demand in Indonesia is likely to intensify, while also underscoring the need for future research using larger datasets and baseline model comparisons before policy-level application can be justified.

Abstract

Traditional fishermen in Surodadi Village face productivity constraints due to their reliance on conventional fishing gear and the lack of post-harvest facilities. This community service program offers a solution through the planned implementation of Internet of Things (IoT)-based Robotic Ship Fishery (RSF) technology and the construction of cold storage infrastructure. The implementation method uses the Participatory Rural Appraisal (PRA) approach, encompassing socialization, technical and managerial training, and hardware engineering, and involves 20 fishermen as target partners. The results indicate that the RSF prototypes are currently undergoing functional laboratory testing, while the construction of the 100 kg capacity cold storage is in the physical development phase. This intervention has significantly improved human resource cognitive capacity, with posttest evaluations showing that 100% of partners (20 people) understand the function of navigation technology for fuel efficiency and 93.3% (19 people) understand cold chain management. It is concluded that the program has successfully established a foundation for human resource readiness and a paradigm shift toward modern, independent fishery businesses. However, the real economic impacts will require monitoring following full implementation of the technology.

Abstract

Sleep disorders are health problems that may affect an individual’s physical condition, mental well-being, and daily productivity. These conditions can be influenced by lifestyle and physiological factors, such as sleep duration, sleep quality, stress level, physical activity, heart rate, and blood pressure. This study aims to apply the Support Vector Machine (SVM) method to classify sleep disorders into three categories, namely normal, insomnia, and sleep apnea, as well as to develop a Streamlit-based web application to support interactive prediction. The dataset used in this study is the Sleep Health and Lifestyle dataset obtained from Kaggle. The research stages include data preprocessing, normalization using StandardScaler, model training using SVM and five comparison algorithms, and hyperparameter tuning to obtain the best performance. The evaluation results show that the SVM model with a poly kernel achieves an accuracy of 97.33% and a macro F1-score of 0.9569. The best model is then implemented into a web application that displays classification results along with the probability of each class, making it useful as an accessible early screening tool for sleep disorders.
