Abstract

This research explores the pervasive issue of cyberbullying, primarily targeting children and teenagers due to their close proximity to communication technologies. Cyberbullying manifests through various forms such as flaming, harassment, and identity impersonation, causing significant psychological and academic impacts on victims. The study, based on a selection of 30 Scopus publications, reveals that cyberstalking holds the highest classification at 90%, followed by flaming at 73%. The consequences of cyberbullying are classified into social (67%), psychological (63%), and academic (57%) impacts. The research emphasizes the need for specific knowledge about cyberbullying in coastal communities, where victims experience feelings of insecurity, isolation, and reduced academic concentration. The conclusion highlights the importance of raising awareness, implementing literacy programs, and enforcing regulations to combat cyberbullying, especially in the context of the Fourth Industrial Revolution. The findings provide valuable insights into the coastal community's perception of cyberbullying, urging parents to play an active role in safeguarding their children and promoting digital literacy.

Abstract

Abstrak Pengelolaan penyiangan buku di Perpustakaan Daerah Kabupaten Kudus masih dilakukan secara manual menggunakan formulir kertas dan Microsoft Excel, sehingga menyebabkan pencatatan yang tidak terintegrasi, rawan kehilangan data, dan pelaporan yang tidak efisien. Kegiatan ini bertujuan mendigitalisasi pengelolaan penyiangan koleksi buku melalui pengembangan dan implementasi Sistem Informasi Penyiangan Buku berbasis web di Dinas Arsip dan Perpustakaan Daerah Kabupaten Kudus. Mitra sasaran kegiatan adalah Perpustakaan Daerah Kabupaten Kudus dengan tiga kelompok pengguna yang terlibat, yaitu Admin, Petugas, dan Kepala Perpustakaan, dengan total 5 peserta yang berpartisipasi aktif dalam proses pengembangan dan implementasi sistem. Metode pelaksanaan menggunakan Rapid Application Development yang terdiri atas empat fase, yaitu perencanaan kebutuhan, perancangan bersama pengguna, konstruksi sistem, dan implementasi. Pengumpulan data dilakukan melalui observasi lapangan, wawancara terstruktur, dan studi literatur. Hasil kegiatan menunjukkan bahwa sistem berhasil dibangun dengan 11 modul fungsional yang dilengkapi mekanisme kontrol akses berbasis peran untuk ketiga pengguna. Modul inti penyiangan buku mampu mencatat proses penyiangan secara digital, memperbarui stok buku secara otomatis, dan merekam seluruh riwayat aktivitas pengguna. Pengujian fungsional terhadap 60 skenario uji pada 9 modul menghasilkan tingkat keberhasilan 100%, sehingga sistem dinyatakan layak diimplementasikan dan terbukti mampu meningkatkan efisiensi serta akurasi pengelolaan penyiangan buku di Perpustakaan Daerah Kabupaten Kudus. Kata kunci: penyiangan buku; sistem informasi perpustakaan; rapid application development; digitalisasi; berbasis Web. Abstract Book weeding management at the Kudus Regency Regional Library is still carried out manually using paper forms and Microsoft Excel, resulting in unintegrated recording, prone to data loss, and inefficient reporting. This activity aims to digitize the management of book collection weeding through the development and implementation of a web-based Book Weeding Information System at the Kudus Regency Regional Library and Archives Service. The target partners of the activity are the Kudus Regency Regional Library with three user groups involved, namely Admin, Officer, and Head of Library, with a total of 5 participants actively participating in the system development and implementation process. The implementation method uses Rapid Application Development which consists of four phases, namely needs planning, design with users, system construction, and implementation. Data collection was carried out through field observations, structured interviews, and literature studies. The results of the activity show that the system was successfully built with 11 functional modules equipped with role-based access control mechanisms for the three users. The core book weeding module is able to record the weeding process digitally, update book stock automatically, and record the entire history of user activity. Functional testing of 60 test scenarios in 9 modules resulted in a 100% success rate, so the system was declared feasible to implement and proven to be able to increase the efficiency and accuracy of book weeding management at the Kudus Regency Regional Library. Keywords: book weeding; library information system; rapid application development; digitalization; web-based.

Abstract

Purpose: This study evaluated an inventory system integrating LSTM forecasting and Hyperledger Fabric blockchain to improve prediction accuracy and transaction integrity. Design/Methods: A design-and-development approach used 12,450 inventory records from Retail Company X (January 2021-December 2023), split chronologically into 70% training, 15% validation, and 15% testing subsets. The LSTM used two hidden layers, 128 units per layer, dropout 0.2, Adam optimizer, learning rate 0.001, batch size 64, and 100 epochs. Blockchain used Hyperledger Fabric with Raft consensus. Evaluation included forecasting benchmarks, 50 stock-modification simulations, and 45 purposively recruited users after hands-on prototype interaction. Findings: LSTM achieved MAE 3.2% and RMSE 4.5%, outperforming Moving Average and Exponential Smoothing. A two-tailed paired-samples t-test across 62 matched testing windows against Exponential Smoothing confirmed significant improvement (t(61) = -5.34, p < 0.001, Cohen's dz = 0.68). Blockchain detected 48 of 50 unauthorized stock modifications, producing a 96% detection rate with two missed detections (4%) and 120 ms latency. User evaluation was positive across forecast accuracy, security, transparency, ease of use, and intention to use. Implications: The prototype can support inventory planning, auditability, and secure transaction records. Originality: The study empirically combines AI forecasting, permissioned blockchain integrity, and user acceptance in one inventory workflow.

Abstract

Transformasi digital dalam pelayanan publik menjadi kebutuhan penting untuk meningkatkan kualitas pelayanan administrasi di instansi pemerintahan. Namun, masih terdapat banyak kantor kecamatan yang melakukan pengelolaan administrasi secara manual sehingga proses pencatatan, pengolahan, dan pencarian data menjadi kurang efektif serta berpotensi menimbulkan kesalahan. Oleh karena itu, kegiatan ini bertujuan untuk mengimplementasikan SIREKAP (Sistem Informasi Rekapitulasi Administrasi) sebagai upaya mendukung transformasi digital dalam pelayanan administrasi di kantor kecamatan. Sistem ini dirancang untuk membantu pengelolaan data administrasi data Kartu Keluarga (KK), Kartu Tanda Penduduk (KTP), legalisasi, Surat Keterangan Waris (SKW), pencatatan NTCR (Nikah, Talak, Cerai, Rujuk),perpindahan penduduk, serta administrasi surat lainnya. Metode pengembangan sistem yang digunakan adalah Waterfall Model, yang meliputi tahap analisis kebutuhan, perancangan sistem, implementasi, dan pengujian sistem. Sistem SIREKAP dikembangkan berbasis web menggunakan framework Laravel, bahasa pemrograman PHP, serta basis data MySQL. Hasil implementasi menunjukkan bahwa sistem ini mampu membantu pegawai kecamatan dalam mengelola data administrasi secara lebih terstruktur, mempercepat proses pencarian data, serta meningkatkan efisiensi pelayanan administrasi kepada masyarakat.

Abstract

Gold is widely recognized as a safe-haven asset whose price is sensitive to economic and geopolitical uncertainty. This study develops a web-based international gold price prediction system using the Gated Recurrent Unit (GRU) algorithm and evaluates the contribution of geopolitical sentiment from the X social media platform. The study uses historical XAUUSD data and English-language posts related to the Iran–United States–Israel conflict. Text data were processed through cleaning, case folding, tokenization, stopword removal, lemmatization, TF-IDF transformation, and sentiment analysis using VADER. The resulting daily sentiment scores were integrated with historical gold price features and used as an additional input to the GRU model. Two experimental scenarios were evaluated: GRU without sentiment and GRU with sentiment. The results show that the GRU model without sentiment achieved an MAE of 55.07, RMSE of 69.81, MAPE of 1.17%, and R² of 0.9629, while the model with sentiment achieved an MAE of 80.87, RMSE of 92.93, MAPE of 1.72%, and R² of 0.9342. These findings indicate that incorporating daily aggregated social media sentiment did not improve prediction performance for the dataset used. The developed Flask-based web application provides prediction, sentiment analysis, visualization, and model evaluation features, demonstrating the practical implementation of the proposed approach.
