Pemakaian komputer dewasa ini semakin luas di segala bidang. Lamanya penggunaankomputer dianjurkan tidak lebih dari 4 jam sehari. Apabila melebihi waktu tersebut, mata cenderungmengalami kelelahan. Kelelahan mata tersebut akan meningkat apabila kualitas pencahayaan diruang kerja tersebut kurang baik. PT. XYZ adalah perusahaan yang bergerak dalam pengolahanproduk makanan ternak, dimana sebagian besar proses produksi dijalankan oleh mesin. Prosesproduksi tersebut diatur dan diawasi oleh 3 operator melalui komputer di dalam ruang kontrolselama 7 jam kerja. Setiap operator bekerja mengamati display dari 4 monitor. Pada penelitian awal,tingkat pencahayaan pada ruang kontrol PT. XYZ bekisar antara 21-65 Lux. Pencahayaan tersebuttidak memenuhi standar Kepmenkes Nomor 1405/MENKES/SK/XI/2002 yang merekomendasikansebesar 300 lux. Beberapa keluhan kelelahan mata yang didapat dari wawancara dengan operatoryaitu operator merasakan keluhan penglihatan seperti berkabut, mata perih dan mata seringberkedip. Oleh karena itu penelitian ini dilakukan untuk melihat pengaruh pencahayaan terhadapkelelahan mata operator, dan memperbaiki pencahayaan sesuai dengan standar kebutuhan kerja.Penelitian ini bersifat kuantitatif karena dilakukan pengukuran langsung terhadap iluminasi sumbercahaya dan luminansi dari monitor dengan menggunakan instrumen lux meter serta kelelahan matadengan instrumen fliker fusion. Metode penelitian bersifat deskriptif korelasional, yaitu untukmendapatkan gambaran mengenai tingkat pencahayaan ruang kontrol dan dibandingkan denganstandar yang sudah ditetapkan, serta mengkaji keterkaitan antara faktor iluminasi dan luminansiterhadap kelelahan mata operator. Hasil perhitungan korelasi antara tingkat iluminasi dan luminansikelelahan mata menunjukan bahwa terdapat hubungan yang rendah, hal ini menunjukkan bahwailuminasi dan luminansi bukan faktor dominan penyebab kelelahan mata.

The main problem faced by students in the vocational field is the lack of specificity in the scientific field that focuses on mastering the knowledge, skills, and attitudes needed in the world of work. In addition, the emphasis on learning by doing the role of the student-centred learning approach becomes less attention from educators. This study aims to develop and implement an experiential learning design in the nautical science program through student worksheets based on the Kolb experiential learning stages by considering the Felder- Silverman student learning style and analyzing student attitudes and responses after participating in learning activities. We used the field case study method (case study research) with qualitative descriptive data analysis techniques. The results showed that the learning style preferences of nautical science students from the learning style categories: (1) 87.41% were categorized as active; (2) 84.44% were categorized as visual; (3) 81.48% were categorized as sensing; and (4) 57.04% were categorized as sequential. The results also show that the experiential learning design is feasible for using learning models and learning material assessments. The implementation of experiential learning activities was carried out very well. Learning activities are carried out on force based on the stages of concrete experience, reflective observations, abstract conceptualization, and active experimentation. Students' attitudes and responses are positive towards the experiential learning design. Experiential activities help students learn Basic Mechanical Engineering Design (cognitive), and they like to participate in learning activities (affective). The experiential design is practical in learning, canin learning, career theory and practice learning. H o w e v e r , some students respond that experiential learning activities are less challenging and too much of a task because they prefer to avoid many tasks.
