Abstract

Machine learning-based classification techniques are widely utilized for accurate analysis in various fields. This study focuses on assessing lecturer performance in higher education to enhance teaching standards and produce high-quality learning outcomes. Previous studies have employed multiparameter approaches, such as statistical correlation analysis, but these methods fail to achieve optimal accuracy and precision due to limited alignment with data characteristics. This research proposes a lecturer performance measurement model by evaluating three machine learning algorithms: k-Nearest Neighbors (k-NN), Decision Tree, and Na¨pve Bayes. The model integrates three feature selection techniques to improve classification performance: ANOVA, Information Gain, and Chi-Square. The study aims to enhance classification accuracy and assess the impact of feature selection techniques on performance metrics. A significant contribution of this research is introducing a dynamic feature selection approach tailored to data characteristics, which improves classification model performance. The methodology comprises three main stages: data loading and measurement of relevant parameters; data preprocessing, including filtering, cleaning, transformation, normalization, and feature selection; and performance evaluation using a machine learning-based classification approach. Experimental results demonstrate that the Decision Tree algorithm combined with Chi-Square feature selection achieved an accuracy of 0.887, precision of 0.903, recall of 0.887, and F1-score of 0.884. The proposed modelprovides a reliable framework for evaluating lecturer performance and can be utilized to recognize and reward high-performing lecturers effectively.

Abstract

Welding workshop MSMEs are businesses that make doors, light steel roofs, canopies and other materials made from aluminium and iron. Dewi Jaya Welding Workshop MSME is one of the MSMEs in the Tabanan Regency - Bali area, established in 1997. The obstacle faced by this MSME is limited production variants due to limited production equipment, which is still conventional and manual. Besides, several work safety procedures have yet to be carried out optimally. So, in the service activities, activities are proposed to provide production equipment and work safety training to improve, develop production variants, and create a safe environment for working at the Dewi Jaya Welding Workshop UMKM. The method of service activities carried out is mentoring and training. The activity results showed an increase of 2-5 product variants and succeeded in increasing 21% income. The results of the activity showed that there was an increase of 2-5 product variants and succeeded in increasing 18.28% revenue from March to Mei 2024. The new variants produced are a prayer place made of light iron and aluminum, and a kitchen set made of light iron. Income increases based on the number of orders for the new variant product types. This increase is expected to improve the welfare of the Dewi Jaya Welding Workshop MSMEs. The results of training activities show that workers and owners during production have used work safety standards. This was proven during the activity evaluation, workers used safety equipment such as gloves and welding glasses when welding.

Abstract

Academic Information Systems play a crucial role in supporting academic data management, administrative processes, and informed decision-making within higher education institutions. Despite their widespread adoption, the extent to which these systems effectively meet the needs and expectations of lecturers, their primary users, remains insufficiently explored. Understanding user satisfaction is critical, as it directly influences system acceptance, continued usage, and overall institutional performance. This study aims to evaluate lecturer satisfaction with Academic Information Systems at Bandung University of Technology by integrating two complementary evaluation methods, the System Usability Scale and End User Computing Satisfaction. The integration of these methods enables a more holistic assessment by combining usability measurements with multidimensional user satisfaction indicators. The findings reveal an exceptionally high SUS score of 99.94, classified as Best Imaginable, indicating that lecturers perceive the system as highly usable, intuitive, and supportive of their academic tasks. The EUCS analysis identifies Accuracy, Format, and Ease of Use as significant factors influencing lecturer satisfaction. These variables demonstrate the importance of accurate and reliable information, a well-structured interface, and system features that facilitate efficient task completion. The combined results highlight specific areas requiring strategic improvement, particularly in maintaining data accuracy, enhancing interface design consistency, and strengthening overall usability to accommodate users’ academic workflows. Theoretically, it demonstrates the added methodological robustness gained from combining SUS and EUCS in evaluating academic information systems, thereby ensuring more substantial alignment with user

Abstract

Pemantauan aliran air secara real-time pada jaringan distribusi pipa menjadi aspek krusial dalam menjamin ketersediaan air bersih bagi masyarakat, khususnya di daerah pedesaan. Pelaksanaan kegiatan pengabdian kepada masyarakat (PKM) yang telah dilakukan dan merupakan hilirisasi dari pelaksanan penelitian, mengembangkan rancang bangun sistem monitoring berbasis Internet of Things (IoT) untuk mendeteksi keberadaan aliran air pada pipa utama yang mensuplai kebutuhan air warga di Desa Gobleg. Sistem ini mengintegrasikan tiga jenis sensor, yaitu pressure sensor, water flow sensor dan contactless water level sensor, yang dipasang pada beberapa titik kritis jaringan pipa. Data dari sensor dikirimkan secara periodik melalui modul komunikasi GSM menggunakan protokol MQTT ke server pusat. Aplikasi Android dikembangkan untuk menampilkan status aliran air secara langsung dan memberikan notifikasi ketika ketiga sensor secara simultan tidak mendeteksi adanya air, yang mengindikasikan potensi kebocoran atau gangguan distribusi. Hasil pengujian menunjukkan sistem mampu mendeteksi kondisi abnormal dengan tingkat akurasi 95% dan memberikan notifikasi dalam waktu kurang dari 10 detik sejak kejadian terdeteksi. Sistem ini diharapkan dapat menjadi solusi efektif dan terjangkau untuk pengawasan distribusi air di wilayah pedesaan.

Abstract

Gangguan hama burung pada lahan pertanian, khususnya di area persawahan, menjadi salah satu faktor yang menyebabkan penurunan hasil panen. Penelitian ini bertujuan untuk mengembangkan sebuah alat otomatis berbasis sistem tertanam (embedded system) yang berfungsi sebagai pengusir burung di sawah. Alat ini bekerja dengan menarik tali lonceng secara otomatis, sehingga menghasilkan bunyi yang dapat mengusir burung secara efektif. Sistem ini terdiri dari beberapa komponen utama, yaitu panel surya sebagai sumber energi, motor penggerak, lengan penarik, dan mikrokontroler sebagai pusat kendali. Mikrokontroler diatur untuk menggerakkan lengan penarik dan mengatur waktu operasional secara otomatis. Hasil pengujian menunjukkan bahwa alat ini mampu beroperasi secara stabil dan efektif dalam mengusir burung, serta dapat bekerja secara mandiri dengan memanfaatkan energi terbarukan dari panel surya. Dengan demikian, alat ini diharapkan dapat menjadi solusi praktis dan berkelanjutan dalam mengatasi masalah hama burung di sektor pertanian.
