Abstract

Pencahayaan menjadi peranan penting untuk membantu aktivitas belajar mengajar dalam suatu instansi pendidikan. Ruang Sidang Fisika ITS menjadi salah satu fasilitas penunjang di ITS. Kenyamanan visual pencahayaan dan kebutuhan intensitas cahaya yang diperlukan di ruang sidang belum terpenuhi. Ruang sidang Fisika ITS menjadi objek pada penelitian ini. Dengan tujuan mengetahui desain pencahayaan paling optimal dan efisien terhadap energi menggunakan lighting management system di ruang sidang Fisika ITS. Standar acuan intensitas cahaya minimum ialah 250 lux menurut SNI-03-6575-2001. Menggunakan simulasi DIALux evo 9.2 untuk pengoptimalannya. Pengukuran hanya dilakukan di bagian work area dengan luas 86.23 m2, sehingga yang diolah data hanya 28 dari 40 titik pengukuran. Pengukuran dilakukan dengan 2 variasi, yakni ketika lampu menyala dan mati. Intensitas cahaya rata-rata ketika lampu dinyalakan adalah 135.5 lux sedangkan ketika lampu mati (mengukur daylighting) adalah 26.4 lux. Dari hasil tersebut, menjadi penting adanya bukaan (jendela) agar ruangan memiliki daylighting yang cukup. Validasi antara hasil simulasi yang senilai 132 lux dengan pengukuran, menghasilkan perbandingan 0.974, artinya penggunaan simulasi untuk pengoptimalan hampir akurat. Selanjutnya, dilakukan perhitungan dan didapatkan beberapa variasi untuk desain optimal serta efisiensi energi. Dengan jumlah titik lampu 7, 8, 12, 13 dan 16. Dipilih lampu SIMPLITZ Panel 32W 3520 lumen L60x60 dari OSRAM untuk pengoptimalan ataupun efisiensi energi. Intensitas cahaya rata-rata paling optimal adalah pada titik lampu sebanyak 12. Karena senilai 337 lux, sudah sesuai dengan acuan rekomendasi dan tidak terlalu terang serta persebaran cahaya yang merata. Dengan LMS, sensor yang dibutuhkan berjumlah 6 sehingga menghasilkan efisiensi energi kurang dari 384. Desain yang paling efisien adalah titik lampu sebanyak 7. Total daya yang dibutuhkan 224 W dengan intensitas cahaya rata-rata 208 lux. Dengan LMS, sensor yang dibutuhkan sebanyak 5 dan menjadi lebih efisien karena konsumsi daya kurang dari 224 W.

Lighting being an important role to help teaching and learning activities in an educational institution. The ITS Physics courtroom is one of the supporting facilities at ITS. The visual comfort of lighting and light intensity not required in the courtroom. The ITS Physics courtroom is the object of this research. To know the most optimal and energy-efficient lighting design using a lighting management system in the ITS Physics courtroom. The minimum light intensity reference standard is 250 lux according to SNI-03-6575-2001. Using DIALux evo 9.2 simulations for optimization. Measurements were only carried out in the work area with an area of 86.23 m2, so that only 28 of the 40 measurement points were processed. Measurements are carried out with 2 variations, namely when the lights are on and off. The average light intensity when the lamp is turned on is 135.5 lux while when the lamp is off (measuring daylighting) it is 26.4 lux. From these results, it is important to have openings (windows) so that the room has sufficient daylighting. The validation between the simulation results which are worth 132 lux with the measurement, results in a comparison of 0.974, meaning that the use of simulation for optimization is almost accurate. Furthermore, calculations are carried out and several variations are obtained for optimal design and energy efficiency. With the number of light points 7, 8, 12, 13, and 16. The SIMPLITZ Panel 32W 3520 lumen L60x60 lamp was selected from OSRAM for optimization or energy efficiency. The most optimal average light intensity is at 12 light points. Because it is worth 337 lux, it is by with the recommendation reference and is not too bright and the light distribution is even. With LMS, 6 sensors are needed, resulting in an energy efficiency of less than 384. The most efficient design is 7 light points. The total power required is 224 W with an average light intensity of 208 lux. With LMS, 5 sensors are needed, and it becomes more efficient because the power consumption is less than 224 W.
