Bentuk pembinaan bagi anak usia dini adalah pemberian rangsangan pendidikan agar anak tersebut memiliki kesiapan dalam memasuki jenjang pendidikan selanjutnya. Salah satu pendidikan dasar dan menjadi kurikulum dasar yang diajarkan orang tua kepada anaknya adalah pendidikan agama yang berupa pengenalan huruf hijaiyah. Lebih seringnya anak-anak berinteraksi menggunakan handphone dibanding dengan buku menyebabkan para orang tua yang mengajarkan anaknya membaca dan menulis dengan berpedoman pada buku dan poster-poster menjadi kurang menarik minat anak-anak tersebut untuk belajar karena merasa terlalu monoton. Dari permasalahan itulah sehingga penelitian kali ini penulis ingin membangun sebuah aplikasi pembelajaran berbasis android dengan menggunakan media smartphone. Media pembelajaran akan dilengkapi dengan suara pengucapan lafal huruf hijaiyah, serta memberikan evaluasi kepada anak-anak untuk dapat belajar menghafal dan menebak huruf hijaiyah secara benar dan tepat. Media pembelajaran yang dibangun diharapkan dapat menarik minat belajar anak-anak usia dini dalam mengenal huruf hijaiyah dan membantu orang tua memperkenalkan tulisan tulisan arab kepada anak mereka.

Sistem penyeleksian penerima beasiswa masih memungkinkan terjadinya kesalahan yang disengaja ataupun tidak disengaja sehingga output menjadi kurang optimal dan dapat berakibat seleksi penerima beasiswa menjadi tidak objektif. Dari masalah ini sehingga dibutuhkan sebuah sistem yang dapat membantu manusia dalam memberikan pertimbangan keputusan yang akan kita ambil atau dikenal dengan Sistem Pendukung Keputusan (SPK). Beasiswa Peningkatan Prestasi Akademik (PPA) merupakan beasiswa yang acuan penilaiannya adalah dilihat dari nilai IPK (Indeks Prestasi Komulatif), Satuan Kredit Semester (SKS), Prestasi, dan Kemampuan Ekonomi. Sistem Pendukung Keputusan (SPK) merupakan solusi yang efektif , dikarenakan dapat memberikan penilaian terhadap setiap alternatif untuk mencapai pilihan yang terbaik. Sistem Pendukung Keputusan (SPK) mempunyai metode untuk memberikan dukungan dalam proses pengambilan keputusan, yaitu Fuzzy Multiple Attribute Decision Making (FMADM) digunakan untuk menentukan nilai bobot untuk setiap atribut, kemudian dilanjutkan dengan proses perangkingan yang akan menyeleksi alternatif yang sudah diberikan dengan algoritma Weighted Product (WP).

Rice is a food crop commodity that produces rice which plays an important role in the economic life of Indonesia. Rice as a staple food is very difficult to replace by other staples. This study aims to determine the results of the design of the internet-based monitoring system for rice field irrigation and to determine the results of monitoring soil pH with Thinger.io. The tools used in the design of this system are Node MCU ESP8266, Ultrasonic Sensor HC-SR04, Soil pH Sensor, Servo Motor (MicroServo 9G – SG90), UTP Cable. Soil pH sensor can send soil acidity level data to NodeMCU and send data to thingger to display results, while ultrasonic sensor can read elevation value on surface if water level (11 cm) then servo will receive signal to open and when water level height value ( 6 cm) then the servo will receive a signal to close, the last process is to send data to the web server or thingger.io. The results of the pH test are that with a pH value equal to 7 then it is suitable for planting rice seeds and if the pH value is below 7 then it is not suitable for planting rice and dolomid lime will be added to neutralize the acidity level in the soil of paddy fields. The tests carried out are using the BlackBox method and the results of this test are the system runs as expected

The traditional perimeter-based security model has proven inadequate in addressing modern cybersecurity challenges characterized by cloud adoption, remote work, and sophisticated cyber threats. This mixed-methods study examines Zero Trust Architecture (ZTA) as an emerging paradigm that fundamentally shifts security principles from "trust but verify" to "never trust, always verify." Through systematic literature review of 156 peer-reviewed articles and analysis of 12 cross-sector implementation case studies, this research explores the core principles, implementation strategies, benefits, and challenges of ZTA adoption. Key quantitative findings demonstrate that organizations implementing ZTA achieve 67% reduction in breach costs, 48% improvement in threat detection, and 52% enhancement in incident response capabilities. However, implementation faces significant barriers including technical complexity (78% of organizations), cultural resistance (65%), and skills gaps (72%). This study contributes a novel cross-sector ZTA maturity framework and provides evidence-based insights for cybersecurity professionals and organizational leaders considering ZTA adoption.

Writing of scientific paper is done by following specified rules and regulations. In reality there are many students at the Faculty of Engineering, University of Sulawesi Barat who do not understand this well, for example: not paraphrasing quotations and not including reference sources correctly. Mendeley application can help students in writing scientific papers or final assignments but it still underutilized by students. This shows the importance of reference citing skills and utilizing the Mendeley application. So, it is necessary to conduct scientific paper citation training. The training was done through planning, training and evaluation activities. Planning aims to prepare and determine the needs during the training. The main activity, training, was organized for two days using a webinar concept on the first day which focused on providing material for preparing scientific work references and a training concept on the second day which focused on practice using Mendeley and coaching research proposals. Last activity, an evaluation was carried out to measure the successfulness of the training and further plans related to similar activities. The results of the training activities showed the participation of 68 students on the first day and 36 students on the second day. The results of the survey showed 100% of students who participated in training felt the benefits of the training therefore they hoped similar activities could be held every year. Another evaluation result is that student supervision should be done in small groups, so the reception of material more effective regarding how to cite scientific papers.

Open Journal Systems (OJS) has become the dominant platform for scholarly journal publication in Indonesia, with more than 8,500 active journals in 2024. However, the growing cyber threats targeting academic infrastructures demand the development of digital forensic methodologies specifically tailored to the OJS ecosystem. This research develops a comprehensive framework for digital forensic investigation on the OJS platform through the analysis of 45 security incidents that occurred in Indonesian scholarly journals during the 2022–2024 period. The proposed Digital Forensic for Academic Publishing (DFAP) methodology covers preservation, acquisition, examination, analysis, and presentation, specifically designed for the OJS architecture. The implementation of this framework in 12 real-world cases demonstrated a success rate of 89.3% in data recovery, 76.2% in perpetrator identification, and 94.4% in operational system restoration, with an average resolution time of 72 hours. The study also identified 15 common vulnerability patterns in Indonesian OJS installations and produced 28 security recommendations that can reduce incident risks by up to 67%. The main contributions of this research include the development of OJS-specific forensic tools, the standardization of investigation procedures for academic institutions, and the establishment of the Indonesian Academic Digital Forensic Database (IADFD) as a knowledge-sharing repository.
