Abstract

Tujuan dari artikel ini untuk mengidentifikasi penyebab resiko pada perusahaan terkait budaya keselamatan berdasarkan pendekatan proses produksi. Metode yang digunakan adalah eksplorasi beberapa data dari sebuah perusahaan X di Surabaya, dikhususkan pada departemen Produksi. Selanjutnya didiskusikan dengan para pimpinan dan yang terkait dengan kinerja produksi. Hasil menunjukkan bahwa penyebab resiko yang dapat membahayakan keselamatan pekerja produksi, dan kebijakan peningkatan kinerja produksi selama ini belum mengedepankan keselamatan pekerja, sehingga dibutuhkan komitmen baru dalam hal keselamatan pekerja. Reorientasi kepemimpinan dalam mengedepankan keselamatan sangat dibutuhkan dalam pembentukan perilaku dan budaya keselamatan di dunia industri. Reorientasi tersebut dilakukan melalui komitmen keselamatan pada level individu, level aturan dan level manajemen.

Abstract

This study introduces Interval Track Lighting (ITL), an innovative, programmable visual pacing system designed to enhance the efficacy of interval training among competitive swimmers. Despite interval training's recognized physiological benefits, its practical application in aquatic sports often suffers from imprecise pacing, reliance on verbal cues, and limited individualization. ITL addresses these challenges by providing real-time visual feedback via synchronized LED lights installed along the swimming lane, allowing swimmers to match their strokes to target time intervals set by coaches. This research employed a Research and Development (R&D) framework using the ADDIE model comprising analysis, design, development, implementation, and evaluation phases. A prototype was developed and tested over 14 training sessions involving eight age-group swimmers. The effectiveness of the ITL system was evaluated through a mixed-method approach combining pretest-posttest sprint performance, structured observations, interviews, and surveys. The results revealed a statistically significant improvement in 50-meter sprint times (mean improvement = 0.84 seconds; p = 0.014; Cohen’s d = 0.87), with swimmers reporting enhanced pacing accuracy and focus. Coaches highlighted ITL’s usability and contribution to reducing cognitive and logistical load during training. The findings suggest that ITL not only improves interval training outcomes but also fosters athlete autonomy and supports self-regulated learning. This study contributes to the growing field of technology-assisted sports training by offering a scalable, evidence-based solution for optimizing performance in swimming and potentially other time-regulated sports.
