Abstract

The need for fast, stable, and affordable internet access is increasing along with the increasing dependence of society on information technology, especially in small business environments such as coffee shops and cafes. However, the operational costs of internet services are still a major challenge for micro-business owners. This study aims to design and implement a coin-based WiFi system that is independent, cost-effective, and easy to operate. This system integrates a coin sensor, microcontroller, and Raspberry Pi to detect coin denominations (Rp500 and Rp1000), automatically converts them into WiFi access duration, and records transactions in a local SQLite-based database. The web-based interface is built using Flask for ease of system administration and management. The research methods include literature studies, field observations, user interviews, and technical testing of sensor accuracy and network performance. Evaluations are carried out on download/upload speeds, latency, jitter, and packet loss to assess connection quality. The test results show that the system is able to detect coins with high accuracy and provide stable internet services according to the payment duration. The advantages of this system lie in its independence that does not depend on third-party applications, as well as its ability to be implemented in environments with technological and budget constraints. This system has the potential to be a viable alternative solution to expand internet access in the informal sector and drive digital transformation at the grassroots level.

Abstract

The growing popularity of mountain climbing among novice participants has been accompanied by an increased risk of accidents, largely attributable to inadequate understanding of safety procedures. Conventional safety induction methods—primarily verbal briefings and printed materials—lack interactivity and fail to adequately simulate real climbing conditions. While prior research has examined general safety education and conventional multimedia learning approaches, the application of markerless augmented reality (AR) as an interactive, mobile-based safety induction tool specifically designed for beginner mountain climbers remains underexplored . Accordingly, this study aims to develop and evaluate an Android-based markerless AR application to enhance pre-climbing safety induction for novice climbers.  The application was developed following the Multimedia Development Life Cycle (MDLC), encompassing the stages of concept development, design, material collection, assembly, testing, and distribution. Functional performance was assessed using black-box testing, while feasibility was evaluated through a Likert-scale questionnaire administered to 20 beginner climbers.  Black-box testing confirmed that all system functionalities operated as intended. The feasibility evaluation yielded a score of 87%, indicating a good to very good level of acceptance among users. By integrating markerless AR technology into mobile-based safety induction, this study addresses a critical gap in outdoor safety training research. The findings demonstrate the feasibility and practical potential of immersive AR applications to enhance safety awareness and improve the effectiveness of preparatory training for beginner mountain climbers.

Abstract

Keselamatan dan kesehatan kerja (K3) merupakan aspek penting dalam operasional industri, khususnya pada area Instalasi Pengolahan Air Limbah (IPAL) yang memiliki tingkat risiko tinggi. Salah satu upaya penerapan K3 adalah memastikan kepatuhan penggunaan Alat Pelindung Diri (APD) oleh operator. Namun, pengawasan secara manual memiliki keterbatasan dari segi efektivitas dan konsistensi. Penelitian ini bertujuan untuk mengembangkan sistem deteksi penggunaan APD secara otomatis menggunakan algoritma You Only Look Once versi 5 (YOLOv5). Metode penelitian meliputi pengumpulan dan pelabelan data, praproses data, pelatihan model, serta pengujian sistem menggunakan citra dan gambar yang diperoleh dari rekaman CCTV. Hasil penelitian menunjukkan bahwa model terbaik diperoleh pada skenario dengan resolusi 416, batch size 16 dan 120 epoch, dengan nilai mAP sebesar 89.02%. Sistem mampu mendeteksi objek APD seperti helm dan sepatu keselamatan dengan akurasi tinggi, namun mengalami penurunan performa pada objek berukuran kecil seperti masker dan sarung tangan, terutama pada kondisi pencahayaan rendah dan oklusi. Secara keseluruhan, sistem yang dikembangkan berpotensi mendukung pengawasan penggunaan APD secara real-time di lingkungan IPAL.
