Abstract

Community service as one of the pillars of higher education occupies a strategic position in drawing and educating the community to improve the quality of life of the community. The form of coaching that is considered the most realistic is none other than providing provision through skills training and mentoring that is considered useful for the local community audience. The low awareness of taxpayers to comply with taxes is the biggest problem faced by the Directorate General of Taxes (DGT) while the government's largest source of funds to finance development is obtained from tax collection, the mechanism of which is coercive in accordance with Indonesian laws and regulations The desire to change people's mindset to be aware of taxes with early education requires systematic technical means, one of which is through inclusion in learning materials and training activities for various groups including private workers or private employees. The implementation method is the counseling method, by going through the preparation stage, the implementation stage and the results stage. Based on the results of the PKM team's observations during the activity, the interest from private employees towards the material provided was very high. The enthusiasm of the participants and the average participant were active in listening to the counseling material. This observation is shown by the high curiosity of private employees so that many questions are asked to the informants. The activity of the resource persons who also asked questions to the participants how far they knew taxation was shown by the many questions asked in the PKM counseling

Abstract

Penelitian ini dilakukan karena pemilihan strategi promosi di Efraim’s Billiard Tangerang Selatan sebelumnya belum memiliki dasar penilaian yang terstruktur dan objektif, sehingga diperlukan suatu sistem yang mampu membantu pengambilan keputusan secara lebih tepat. Penelitian ini bertujuan merancang Sistem Pendukung Keputusan berbasis web menggunakan metode Simple Multi Attribute Rating Technique (SMART) untuk menentukan strategi promosi paling efektif melalui pengolahan data pelanggan dan penilaian kriteria secara sistematis. Metode penelitian meliputi observasi, wawancara, kuesioner, dan studi pustaka, sedangkan pengembangan sistem menggunakan model Waterfall yang terdiri dari analisis kebutuhan, perancangan, implementasi, pengujian, dan pemeliharaan. Proses perhitungan SMART mencakup penentuan kriteria, pembobotan, pemberian skala nilai, normalisasi, perhitungan nilai akhir, dan perangkingan. Hasil penelitian menunjukkan bahwa alternatif A5 (Event Turnamen Billiard Berhadiah) memperoleh nilai tertinggi sehingga direkomendasikan sebagai strategi promosi terbaik. Sistem ini mampu meningkatkan objektivitas pengambilan keputusan dan efektivitas promosi. Temuan ini diharapkan dapat membantu pelaku usaha dalam menentukan strategi pemasaran yang lebih tepat sasaran dan berkelanjutan.

Abstract

Teacher performance evaluation plays a strategic role in sustaining instructional quality, yet existing appraisal systems in educational settings are often designed for conventional schools and lack structured computational frameworks capable of capturing the multidimensional demands of nature-based and spiritually integrated institutions. This study develops a web-based Decision Support System (DSS) integrating the Simple Multi-Attribute Rating Technique (SMART) to operationalize teacher performance assessment at Sekolah Alam Tahfidzpreneur, which combines academic instruction, Quran memorization, entrepreneurship, and outdoor learning. Unlike prior SMART-based implementations that primarily focus on score automation, this study formalizes weight rationalization, explicit benefit–cost criteria structuring, and utility normalization to enhance decision transparency and methodological replicability. Ten performance criteria were defined and weighted through institutional policy alignment, and teacher ratings were transformed into normalized utility scores to generate composite rankings. The system produced consistent performance stratification across eleven teacher alternatives, with top-ranked scores exceeding the institutional evaluation threshold. Efficiency gains and reduced subjectivity were inferred through comparative process mapping against the prior manual interview-based approach, demonstrating shorter evaluation cycles and explicit audit trails of weighting and scoring logic. By externalizing evaluation assumptions and computational procedures, the proposed DSS strengthens accountability and supports evidence-based professional development planning. The findings demonstrate that structured multi-criteria modeling can provide a transparent and replicable governance mechanism for complex hybrid educational environments.

Abstract

Indonesia possesses exceptional spice biodiversity, yet public familiarity with the original visual characteristics of many spices is declining because of packaged processing, reduced direct exposure, and changing food-consumption patterns. This study develops RempahID, a web-based spice identification system that integrates Content-Based Image Retrieval (CBIR) with machine-learning classification. The study addresses the limited availability of Indonesian spice recognition systems that simultaneously provide class predictions and visually similar reference images for user verification. The system uses a dataset comprising ten major spice categories, including ginger, turmeric, galangal, aromatic ginger, cinnamon, cloves, nutmeg, coriander, candlenut, and star anise. Each image is preprocessed through resizing, normalization, noise reduction, and Otsu-based segmentation. Visual representation combines 24 Hue-Saturation-Value color histogram features, four Gray-Level Co-occurrence Matrix texture descriptors, and seven Hu Moment shape features, producing a 35-dimensional feature vector. Euclidean Distance is employed to rank visually similar database images, while K-Nearest Neighbors, Support Vector Machine, and Random Forest are compared for classification. Performance is evaluated using accuracy, precision, recall, and F1-score. The Support Vector Machine with a radial basis function kernel achieved the best result, with 92.1% accuracy, 0.91 precision, 0.92 recall, and a 0.91 F1-score. Retrieved reference images also supported transparent visual comparison rather than presenting an isolated predicted label alone. These findings demonstrate that integrating complementary color, texture, and shape descriptors within a CBIR framework provides an effective and interpretable approach for Indonesian spice identification.
