Abstract

Selection of student majors is one of the decision-making rules in determining majors based on interests and talents, this aims to understand one's potential and existing opportunities. In determining student majors in the 2013 curriculum, it is carried out at the beginning of the first semester, namely in class 10 (X) of senior high school. The implementation of the 2013 curriculum aims to support the adaptation of educational programs by capturing the characteristics and potential of students. [1]. The implementation of the 2013 curriculum had an impact on one of the schools, especially the counseling teacher, who did not know the talents, interests, character and financial capabilities of the students' families to choose certain subjects, so the counseling teacher had to really be able to recommend majors that matched the interests and talents of students. Based on these problems, the application of data mining using the Naïve Bayes algorithm and the Decesion Tree C4.5 algorithm is carried out for classifying student majors at MA El-Bayan Majenang. The Naïve Bayes algorithm [2] and the Decesion Tree algorithm C4.5 [2] are algorithms with a decision tree classification pattern that are used because they have several advantages compared to other algorithms. In this study, the authors compared the two methods, starting with data collection, then cleaning the data and continuing to process data testing and training data. After all the data has been processed, it will proceed to the classification process for each algorithm.

Abstract

Fingerprint image identification plays a crucial role in biometric authentication systems; however, selecting an appropriate algorithm remains challenging due to trade-offs between identification accuracy and computational efficiency. This study aims to comparatively evaluate the performance of a traditional Minutiae-Based algorithm and a Convolutional Neural Network (CNN) for fingerprint image identification to determine their respective strengths and limitations. The Minutiae-Based method extracts distinctive ridge features, such as ridge endings and bifurcations, followed by a similarity-based matching process. In contrast, the CNN model automatically learns discriminative features from raw fingerprint images through deep learning. Experiments were conducted on a multi-subject fingerprint dataset, and performance was assessed using identification accuracy, False Acceptance Rate (FAR), False Rejection Rate (FRR), and computation time per image. The results show that CNN achieved a higher identification accuracy of 98.6%, with a FAR of 1.2% and FRR of 1.4%, outperforming the Minutiae-Based algorithm, which obtained 92.3% accuracy, 4.8% FAR, and 3.9% FRR. However, the Minutiae-Based approach demonstrated superior computational efficiency, requiring an average processing time of 0.42 seconds per image compared to 1.35 seconds for CNN. These findings highlight a clear performance trade-off between accuracy and processing speed. The novelty of this study lies in providing a structured quantitative comparison that integrates accuracy, security metrics, and computational cost within a unified evaluation framework. The results contribute to the development of biometric systems by offering practical guidance for selecting fingerprint identification algorithms based on application-specific requirements, whether prioritizing high recognition accuracy or real-time computational efficiency.

Abstract

Kampung Laut, Kabupaten Cilacap, memiliki sumber daya mangrove yang melimpah, tetapi daun mangrove belum dimanfaatkan secara optimal sebagai produk pangan bernilai tambah. Hasil observasi awal menunjukkan empat persoalan mitra, yaitu pengetahuan yang masih terbatas, kekhawatiran terhadap keamanan bahan, belum tersusunnya proses produksi yang higienis, serta lemahnya aspek pengemasan dan pemasaran. Kegiatan ini bertujuan memperkuat kapasitas ibu-ibu PKK dan kelompok perempuan produktif melalui pembuatan prototipe kerupuk daun mangrove. Program dilaksanakan pada 11 September 2025 di Balai Desa Ujunggagak melalui tahap persiapan dan pemetaan kebutuhan, edukasi, demonstrasi dan praktik, evaluasi formatif, serta penyusunan tindak lanjut. Evaluasi menggunakan tanya jawab terstruktur, observasi partisipasi, dan penilaian unjuk kerja pada tahapan pemilihan bahan, sanitasi, pengolahan adonan, pengukusan, pengeringan, penggorengan, dan pengemasan. Hasil kegiatan menunjukkan peserta mampu menjelaskan potensi dan kehati-hatian pemanfaatan daun mangrove, menyelesaikan seluruh tahapan produksi secara berkelompok, menghasilkan prototipe kerupuk, serta mengidentifikasi kebutuhan label, harga, dan pemasaran sederhana. Perubahan kapasitas dilaporkan secara kualitatif karena kegiatan belum menggunakan instrumen pretest-posttest terstandar. Program ini mengintegrasikan edukasi kesehatan, keterampilan produksi, sanitasi pangan, dan orientasi usaha rumah tangga. Keberlanjutan kegiatan memerlukan autentikasi spesies, pengujian keamanan, proksimat, mikrobiologi, dan sensori, standardisasi formula, pengurusan perizinan, serta pendampingan pemasaran.
