Abstract

Penelitian ini bertujuan untuk memodelkan dan memprediksi jumlah calon santri baru di Pondok Pesantren At-Tadzkir Maja dengan memanfaatkan algoritma Prophet berbasis data harian periode tahun 2022–2025. Dataset yang digunakan berasal dari sistem penerimaan santri baru dan menunjukkan pola fluktuatif yang signifikan, dengan rentang nilai yang bervariasi antara hari dengan jumlah pendaftar rendah hingga hari-hari dengan lonjakan pendaftaran yang tinggi. Setelah dilakukan proses pra-pemrosesan yang mencakup normalisasi tanggal, agregasi harian, serta penyiapan struktur data yang sesuai untuk Prophet, model kemudian dilatih untuk mempelajari komponen tren, musiman mingguan, dan musiman tahunan. Hasil pemodelan menunjukkan adanya tren penurunan jumlah pendaftar dari tahun ke tahun, serta pola musiman yang kuat terutama pada awal pekan dan periode tertentu dalam satu tahun. Evaluasi menggunakan MAE sebesar 1,52 dan RMSE sebesar 2,06 menunjukkan bahwa model mampu merepresentasikan pola historis dengan tingkat kesalahan yang relatif rendah, meskipun tantangan masih muncul pada prediksi lonjakan harian yang bersifat sporadis. Secara keseluruhan, model Prophet terbukti efektif untuk memberikan gambaran prediktif yang dapat dimanfaatkan sebagai dasar perencanaan dan pengambilan keputusan strategis di lingkungan pesantren.

Abstract

Penelitian ini membahas penerapan metode Latent Dirichlet Allocation (LDA) untuk pemodelan topik berita terkini di Indonesia. Data dikumpulkan melalui RSS feed dari beberapa portal berita nasional seperti Detik, Kompas, Tribunnews, Liputan6, Tempo, CNN Indonesia, dan Antara News. Proses penelitian meliputi tahapan pengambilan data, pembersihan dan preprocessing teks, eksplorasi awal frekuensi kata, penyusunan representasi korpus, pemodelan topik LDA, visualisasi interaktif dengan pyLDAvis, serta evaluasi model menggunakan metrik coherence score. Hasil analisis menunjukkan model LDA dengan lima topik memberikan distribusi kata kunci yang relevan dengan isu-isu utama seperti bencana, politik, demonstrasi, korupsi, dan kriminal. Nilai coherence score sebesar 0,3591 mengindikasikan tingkat koherensi cukup baik, meskipun terdapat ruang optimasi melalui penyesuaian parameter. Visualisasi interaktif menunjukkan keterpisahan topik yang memadai, dengan tumpang tindih yang relatif kecil. Temuan ini memperlihatkan bahwa LDA efektif untuk mengidentifikasi topik dominan dalam berita nasional, sehingga dapat dimanfaatkan untuk analisis tren isu publik, pengelompokan konten media, serta mendukung pengambilan keputusan berbasis data.

Abstract

The rapid development of Artificial Intelligence (AI) has significantly influenced various educational practices, including English language learning. Many students still experience difficulties in speaking English due to low self-confidence, fear of making mistakes, and limited opportunities for speaking practice. This community service activity aimed to enhance students’ self-confidence through AI-based English speaking training. The program involved 25 students who participated in interactive speaking practices using AI applications such as ChatGPT and AI voice assistants. The methods employed included training sessions, demonstrations, guided speaking practice, discussions, and evaluations through questionnaires and observations. The results indicated that participants experienced improvements in self-confidence, motivation, and speaking participation after attending the training. Students perceived AI-based learning as a flexible, interactive, and supportive medium for independent speaking practice. Furthermore, the implementation of AI in English language learning created a more comfortable learning environment, reducing speaking anxiety. Therefore, AI-based speaking training was found to be effective in enhancing students’ self-confidence and communication skills in English language learning.

Abstract

Twins Hotel Syariah Bandung is currently developing a digital-based service system to improve the efficiency and quality of services provided to guests. In the room reservation process, the hotel continues to face challenges such as manual data recording, errors in data management, and limitations in reporting. To address these issues, a team of lecturers from YPIB Majalengka of University initiated a training program on a digital hotel room reservation system designed to be simple yet capable of overcoming the classic limitations of manual processes. Furthermore, the need for ease of information delivery, service availability, and accessibility is crucial for the future development of the hotel's business. The activity was carried out in several stages, including system needs identification, system analysis and design, system development, preparation of training materials, implementation of the system in the hotel environment, and intensive training for relevant staff. The methods used include in-person and online training, hands-on practice with the system, and evaluation sessions to identify challenges during and after the training. The results showed an increase in staff skills in using the hotel room reservation application, a reduction in administrative errors, and improved time efficiency in serving guests. Additionally, the system is capable of generating automatic reports that assist management in decision-making. Overall, this community service activity had a positive impact and can serve as a model for the application of information technology-based community engagement that is practical and sustainable.

Abstract

This community service program was conducted to address the need of Pondok Pesantren At-Tadzkir Maja for a more effective planning mechanism regarding the number of new student applicants, which previously lacked a data-driven prediction system. The purpose of this program is to implement a prediction model for forecasting the number of prospective students by utilizing the Prophet algorithm developed in prior research, and to provide an accessible predictive dashboard for operational use by the institution. The implementation involved needs assessment, model integration into the online admission system, dashboard development, user training, and evaluation of the administrators’ understanding. The results indicate that the model runs automatically and produces informative daily forecasts, while the dashboard enables administrators to interpret trend and seasonal patterns to support capacity planning and admission strategies. The program concludes that the implementation successfully improves the pesantren’s ability to make data-driven decisions, and it is recommended that future work integrates additional external variables and ensures regular model updates to maintain predictive accuracy.
