Abstract

This study aims to improve the efficiency of the PVC doll production line at CV. Eye Wind by integrating Time Study and Line Balancing methods using the Ranked Positional Weight (RPW). The research began with data uniformity and adequacy tests, followed by determining standard time through Time Study. RPW was applied to balance the production line, while 5 Whys and 5W+1H methods were used to identify root causes and propose improvements. The results show that the stirring process is the main bottleneck with a standard time of 2,941.28 seconds. This study provides accurate work standards and practical recommendations expected to reduce bottlenecks and increase overall production efficiency

Abstract

Penelitian ini bertujuan merancang sistem kontrol berbasis Internet of Things (IoT) pada tungku pemanas anti nyamuk elektrik untuk meningkatkan efisiensi energi, keamanan, dan kenyamanan pengguna. Perangkat konvensional saat ini masih bersifat manual, rentan overheating serta boros energi. Penelitian menggunakan pendekatan mixed-methods melalui observasi, wawancara, kuesioner, dan metode Quality Function Deployment (QFD) dengan House of Quality (HoQ). Hasil analisis menunjukkan bahwa keamanan produk dan kontrol jarak jauh melalui smartphone menjadi prioritas utama dengan Importance Rating tertinggi. Rekomendasi teknis meliputi penggunaan mikrokontroler ESP32, sensor suhu DHT22, relay proteksi serta aplikasi mobile untuk monitoring real-time serta timer otomatis. Penelitian ini diharapkan dapat menghasilkan prototipe tungku pemanas anti nyamuk yang lebih aman, efisien serta sesuai dengan kebutuhan masyarakat di era smart home.
