Abstract

Teori Dempster-Shafer adalah teori matematika bukti berdasarkan fungsi keyakinan dan penalaran yang masuk akal, yang digunakan untuk menggabungkan bagian yang terpisah dari informasi. Dempster- Shafer teori alternatif teori probabilistik tradisional untuk representasi matematis dari ketidakpastian. Dalam diagnosis penyakit informasi kehamilan yang diperoleh dari pasien kadang-kadang tidak lengkap, dengan metode dan sistem pakar Dempster-Shafer aturan bisa menjadi kombinasi dari gejala yang tidak lengkap untuk mendapatkan diagnosis yang tepat sedangkan pohon keputusan digunakan sebagai alat pendukung keputusan pelacakan referensi gejala penyakit. Penelitian ini bertujuan untuk mengembangkan sebuah sistem pakar yang dapat melakukan diagnosis kehamilan menggunakan metode Dempster Shafer, yang dapat menghasilkan nilai kepercayaan untuk diagnosis penyakit. Berdasarkan hasil tes diagnostik Dempster-Shafer metode dan ahli sistem, akurasi yang dihasilkan dari 76%. Kata kunci: sistem ahli, penyakit kehamilan, dempster shafer.

Abstract

Meningkatnya penggunaan gadget pada anak usia dini (golden age) menimbulkan kekhawatiran terkait dampaknya terhadap perkembangan kognitif, fisik, dan emosional mereka. Penelitian ini bertujuan untuk memprediksi tingkat kecanduan gadget pada anak usia dini menggunakan algoritma Naive Bayes dengan dataset yang terdiri dari 104 responden yang dikumpulkan melalui kuesioner yang divalidasi oleh pakar. Model ini dievaluasi menggunakan metode validasi silang 10 kali lipat untuk memastikan keakuratan prediksi. Hasil penelitian menunjukkan bahwa algoritma Naive Bayes mencapai akurasi 94,36% dengan presisi dan recall yang tinggi pada kategori “normal” dan “kecanduan berat”. Namun, kesalahan prediksi masih ditemukan pada kategori “kecanduan sedang” dan “kecanduan ringan”. Penelitian ini memberikan kontribusi yang signifikan dalam mengidentifikasi hubungan antara kebiasaan penggunaan gadget dan tingkat kecanduan pada anak usia dini, serta memberikan acuan praktis bagi orang tua untuk mengatur pola penggunaan gadget pada anak. Sistem prediksi yang dikembangkan juga dapat menjadi dasar untuk aplikasi berbasis teknologi dalam manajemen perilaku anak. Studi ini merekomendasikan pengumpulan dataset yang lebih besar dan seimbang pada penelitian selanjutnya untuk meningkatkan akurasi prediksi dan memperluas model generalisasi.

Abstract

Having high level human resources that globally competitive is very important in this era of constant changes. The limited use of concrete media contributes to the decline of efficiency, creativity, and involvement in the classes. The purpose of this research is to assess the feasibility and efficiency of various learning media. The ADDIE R&D model is used in this study. The results of the validation test by material and media experts shows a score of 33 out of 40 or 82.5%, which means that this product is "very feasible". The learning expert gives it a score of 38 out of 40 or 95%, which also indicates that the product is "very feasible". The effectiveness test conducted by pretest and posttest shows an increase of 51.6 points, and the questionnaire given to students shows product usability of 90.5%, which means this product is "very feasible". The observation of Pancasila Student Profile Strengthening Project shows that the character of student profile improves from level 2 to level 4. Based on the research result, the “Detective Air” (Water Detective) media can optimally improve learning and can be a reference in facilitating learning process.

Abstract

Purpose: This research aims to assess the maturity level of governance and service management in the Library Information System (SIPERPUS) at UNISNU Jepara. The objective is to identify strengths and gaps, ensuring better alignment with ITIL V4 best practices. Methods: The research was conducted using a qualitative methodology that incorporated a literature review, user questionnaires, and the creation of a web-based audit application designed specifically for this study. Service practices such as Service Request Management, Service Desk, Change Control, and Service Catalog Management were evaluated using the ITIL V4 framework. Result: The findings indicate that SIPERPUS has independently attained a managed maturity level with well-defined Service Request Management and Service Desk practices. Additional work is required to improve Change Control and Service Catalog Management to increase process integration and make information clearer. The new web-based audit application described in this study demonstrates its capability to systematically evaluate, produce data-based recommendations, and continuously improve digital library services. Novelty: This study introduces a new web-based audit application that conforms to ITIL V4, providing an efficient and reliable alternative to manual audit methodologies. The tool significantly reduces audit time, enhances operational efficiency, and optimizes user satisfaction while improving overall service quality. The study adds to the literature on IT governance audits, specifically in higher education, and presents a scalable approach for institutions striving to meet the standards of Society 5.0.

Abstract

Mata pelajaran Seni Budaya dan Prakarya (SBdP) di sekolah dasar memiliki peranan penting dalam mengembangkan kreativitas siswa, terutama melalui keterampilan menggambar. Namun, banyak guru yang menghadapi kesulitan dalam mengajarkan keterampilan ini, terutama karena kurangnya pelatihan dan latar belakang pendidikan di bidang seni rupa. Program pengabdian ini bertujuan untuk meningkatkan keterampilan menggambar guru di SDN 2 Undaan Lor, Kudus, sebagai upaya mendukung implementasi Kurikulum Merdeka. Metode yang digunakan dalam pengabdian ini meliputi sosialisasi, pelatihan, penerapan praktik menggambar, pendampingan, dan evaluasi keberlanjutan. Hasil pengabdian menunjukkan bahwa pelatihan yang diberikan berhasil meningkatkan keterampilan menggambar guru, baik dalam teknik dasar maupun dalam penerapannya di kelas. Sebagian besar guru merasa lebih percaya diri dan kompeten dalam mengajarkan keterampilan menggambar setelah mengikuti pelatihan ini. Evaluasi keberlanjutan menunjukkan bahwa media pembelajaran berbasis gambar juga memberikan dampak positif bagi siswa dengan berbagai gaya belajar. Dengan demikian, program ini tidak hanya meningkatkan keterampilan guru, tetapi juga mendukung tercapainya tujuan kurikulum yang berbasis pada kreativitas dan keterampilan orisinal siswa. Cultural Arts and Crafts (SBdP) subjects in elementary schools have an important role in developing students' creativity, especially through drawing skills. However, many teachers face difficulties in teaching this skill, mainly due to lack of training and educational background in fine arts. This service program aims to improve teachers' drawing skills at SDN 2 Undaan Lor, Kudus, as an effort to support the implementation of Merdeka Curriculum. The methods used in this service include socialization, training, application of drawing practices, mentoring, and sustainability evaluation. The results of the service show that the training provided has succeeded in improving teachers' drawing skills, both in basic techniques and in their application in the classroom. Most teachers feel more confident and competent in teaching drawing skills after attending this training. The sustainability evaluation showed that the drawing-based learning media also had a positive impact on students with various learning styles. Thus, this program not only improves teachers' skills, but also supports the achievement of curriculum objectives based on students' creativity and original skills.
