ANALISIS PERENCANAAN INTENSITAS PENCAHAYAAN ALAMI DAN BUATAN DI LANTAI 1 GEDUNG FAKULTAS TEKNIK BERBASIS DIALUX SOFTWARE

The planning of natural and artificial lighting intensity in building spaces,
particularly classrooms and administrative rooms, is crucial to ensure visual
comfort and energy efficiency. Optimal lighting supports the quality of learning
and reduces reliance on energy-consuming artificial lighting. This study aims to
analyze the lighting intensity planning on the first floor of the Faculty of
Engineering building at Universitas Darul 'Ulum Jombang using Dialux software
and identify factors affecting the distribution of lighting in various rooms. The
data used include floor plans, lighting simulation results from Dialux, and
measurements using a lux meter. The findings indicate that most rooms on the
first floor of the Faculty of Engineering building have inadequate natural lighting.
For instance, the Vice Dean 1 Room has a natural lighting intensity of only 1.8
lux, far below the SNI standard of 300 lux. In contrast, the Classroom has 9.2 lux,
even though the standard for classrooms is 350 lux. The simulation shows that the
natural lighting in the Mini Hall and the Archive Room is fairly adequate, but still
requires improvement. The addition of 19-watt LED Philips CoreLine Downlight
gen5 DN142B 20S PSU-E/4000K WR lights increased the lighting to 429 lux in
the Vice Dean 1 Room and 376 lux in the Classroom, meeting the SNI standards.
This study recommends improvements in architectural design and the integration
of more efficient natural and artificial lighting to enhance visual comfort and
reduce energy consumption.
