Abstract

Lingkungan kerja yang optimal merupakan faktor penting dalam meningkatkan kenyamanan dan kinerja karyawan, terutama di kawasan industri yang dinamis seperti Surabaya. Penelitian terdahulu masih terbatas dalam mengintegrasikan elemen desain interior secara komprehensif dengan *Post-Occupancy Evaluation* (POE) yang tervalidasi secara metodologis. Penelitian ini menganalisis pengaruh elemen desain interior, yaitu tata ruang, pencahayaan, akustik, material, furnitur, ergonomi, dan suhu, terhadap kenyamanan multidimensi (fisik, visual, termal, akustik, dan psikologis) serta kinerja karyawan, dengan kenyamanan sebagai variabel mediasi. Penelitian menggunakan pendekatan *mixed methods* pada PT GMB (Olympic Group), Surabaya, dengan melibatkan 71 dari 141 karyawan sebagai responden (response rate 50,35%). Instrumen utama berupa kuesioner POE berbasis CASBEE dengan skala 0–3, yang dilengkapi observasi lapangan dan pengukuran teknis pada enam area kerja. Analisis meliputi statistik deskriptif, *Item Response Theory* (Graded Response Model) untuk validasi instrumen (41 butir tervalidasi), serta korelasi Pearson dan regresi berganda. Hasil penelitian menunjukkan bahwa lima dari tujuh elemen desain interior, yaitu material (r = 0,667), ergonomi (r = 0,653), furnitur (r = 0,549), tata ruang (r = 0,521), dan pencahayaan (r = 0,392), berpengaruh signifikan terhadap kenyamanan (p < 0,001), sedangkan akustik dan suhu tidak menunjukkan pengaruh yang signifikan, yang diduga disebabkan oleh adaptasi kolektif terhadap kondisi lingkungan yang seragam namun kurang baik. Kenyamanan terbukti menjadi mediator yang kuat antara desain interior dan kinerja (r = 0,741), dengan desain interior mampu menjelaskan 72,9% variasi kinerja (R² = 0,729). Seluruh area kerja juga belum memenuhi standar SNI untuk aspek pencahayaan, akustik, dan suhu. Temuan penelitian ini menghasilkan rekomendasi perbaikan yang memprioritaskan pencahayaan, furnitur, suhu, dan tata ruang, serta menghasilkan instrumen POE-IRT yang tervalidasi dan dapat direplikasi pada penelitian maupun evaluasi lingkungan kerja selanjutnya.

An optimal work environment is a key factor in enhancing employee comfort and performance, particularly in dynamic industrial areas such as Surabaya. Previous studies have been limited in comprehensively integrating interior design elements with a methodologically validated *Post-Occupancy Evaluation* (POE). This study analyzes the influence of interior design elements, including spatial layout, lighting, acoustics, materials, furniture, ergonomics, and temperature, on employees’ multidimensional comfort (physical, visual, thermal, acoustic, and psychological) and performance, with comfort serving as a mediating variable. A mixed-methods approach was employed at PT GMB (Olympic Group), Surabaya, involving 71 of 141 employees as respondents (response rate 50.35%). The primary instrument was a CASBEE-based POE questionnaire using a 0–3 scale, complemented by field observations and technical measurements across six work areas. Data analysis included descriptive statistics, *Item Response Theory* (Graded Response Model) for instrument validation (41 validated items), as well as Pearson correlation and multiple regression analyses. The results indicate that five of the seven interior design elements—materials (r = 0.667), ergonomics (r = 0.653), furniture (r = 0.549), spatial layout (r = 0.521), and lighting (r = 0.392)—have significant effects on comfort (p < 0.001), whereas acoustics and temperature do not show significant effects, presumably due to collective adaptation to uniformly poor environmental conditions. Comfort was found to be a strong mediator between interior design and employee performance (r = 0.741), with interior design explaining 72.9% of the variance in performance (R² = 0.729). Furthermore, none of the work areas met the applicable Indonesian National Standards (SNI) for lighting, acoustics, and temperature. These findings provide practical recommendations prioritizing improvements in lighting, furniture, temperature, and spatial layout, while also contributing a validated and replicable POE-IRT instrument for future workplace evaluation and research.
