Abstract

Eccentricity measurement techniques are developed to ensure optimization of operational works, either for large or small objects such as upper bearing kWH meter. Small object eccentricity testing has been done by using precise and sensitive touch trigger probing and a special sofware that makes it expensive. This study developed a more economical vision systemin eccentricity testing. It consists of bearing holder and CCD microscope as an image recorder and computerized image processing. It uses three tested bearing during image recording process, which obtained 12 images from each tested bearing taken from every 30o angle, and one image as registration reference. Image registration process is conducted to correct imperfections bearing mounting into its holder and use centroid method to test the eccentricity of upper bearing kWH meter. This study is succeed in making an eccentricity testing prototype of upper bearing kWH meter which obtained result of 2nd bearing has its largest standard deviation. From all standard deviation value obtained that x -axis (horizontal) standard deviation is larger than y-axis (vertical) which means that detection of x direction is more accurate than y direction. To enhance precision image acquisition in the next study, it is expected the use of a computer system with homogeneous illumination is enabled.

Abstract

This study aims to analyze the use of digital-based media in enhancing the professional competence of teachers at SMAN 5 Batam. Teacher competence is crucial for improving the quality of learning, and digital technology offers potential strategies for professional development. The research employed a quantitative approach, using descriptive and inferential analyses, with simple linear regression to examine the relationship between digital media use and teacher competence. The results show that integrating digital media positively impacts teachers’ knowledge, pedagogical skills, and learning innovation. The study found a strong correlation between digital media use and professional competence (r = 0.770) and a coefficient of determination of 58.83%, indicating that digital media contributes significantly to competence improvement. Despite these positive outcomes, several challenges were identified, including limited infrastructure, insufficient ongoing training, and resistance to adopting new technologies. The findings suggest that the effective use of digital media can enhance teacher competence when supported by proper policies, continuous training, and capacity-building programs. This research highlights the strategic role of digital technology in teacher development and provides empirical evidence that supports the integration of digital media as a tool to foster professional growth and innovation in education.

Abstract

In the current digital era, Internet of Things (IoT) technology offers innovative solutions to increase efficiency and accuracy in various sectors, including the rice sales business. This journal discusses the design of IoT-based scales specifically designed to help with bookkeeping in rice sales businesses. The main objective of this research is to develop a weighing system that can automatically measure the weight of rice and integrate it with a digital bookkeeping system, thereby minimizing manual errors and increasing operational efficiency. The research methodology includes design of weighing hardware and software, implementation of weight sensors, and development of IoT applications that connect scales with bookkeeping systems. The system is designed to send real-time weight data to a cloud-based bookkeeping platform, enabling more accurate and faster monitoring and reporting. Test results show that this IoT-based scale can provide weight data with high accuracy and seamless integration with the bookkeeping system. Users report increased efficiency in the process of recording and managing rice sales data. In conclusion, IoT-based scales offer an effective solution for modernizing the bookkeeping process in rice sales businesses, supporting better decision making and improving the accuracy of financial reports.

Abstract

Penyortiran barang secara manual berdasarkan atribut warna rentan terhadap kesalahan dan memakan waktu. Penelitian ini bertujuan untuk merancang dan mengimplementasikan sistem penyortiran otomatis menggunakan Siemens S7-1200 PLC, motor servo SIMOTICS S 1FL6, sensor warna GDS3011W untuk deteksi hitam-putih, dan sensor fotolistrik E3F-DS30C4 untuk deteksi keberadaan objek. Sistem ini memiliki mode operasi otomatis dan manual, dikontrol melalui Simatic KTP 700 Comfort HMI, dan mendukung pemantauan jarak jauh melalui Node-RED sebagai platform IoT. Metode pengujian melibatkan validasi posisi motor servo menggunakan busur derajat dan pengukuran kecepatan putar dengan takometer digital. Hasil penelitian menunjukkan bahwa motor servo berhasil menggerakkan tabung putih ke sudut -90° seperti yang diperintahkan dan kembali ke 0° setelah penundaan 5 detik, mempertahankan kecepatan putar 200 mm/s. GDS3011W dan sensor fotolistrik beroperasi dengan andal dalam rentang deteksi yang ditentukan. Integrasi IoT memungkinkan pemantauan waktu nyata terhadap kuantitas dan status objek yang diurutkan.
