Abstract

Konsumsi energi pada sektor bangunan di Indonesia menyumbang hingga 40% dari total energi tahunan, di mana sistem pendingin udara (AC) menyerap 50–60% dan sistem pencahayaan sekitar 7–8,56% dari total energi listrik gedung. Kondisi ini membebani jaringan listrik nasional dan memperbesar emisi gas rumah kaca. Audit energi menjadi langkah strategis dalam konservasi energi, namun pengambilan data lingkungan oleh Dinas Lingkungan Hidup Kota Surabaya masih konvensiona dengan menggunakan tiga alat ukur terpisah dan pencatatan manual, menyebabkan proses audit 31 kantor kecamatan dan 160 kelurahan berlangsung hingga 66 hari serta rentan kesalahan pencatatan. Penelitian ini merancang dan membangun alat ukur lingkungan terintegrasi berbasis Arduino Uno yang mampu mengukur suhu ruangan, kelembapan, intensitas cahaya, dan suhu keluaran AC. Sistem terdiri dari sensor AHT20, VEML7700, dan MLX90614-DCI, dilengkapi tampilan LCD realtime, tombol pengambil data, dan penyimpanan otomatis ke kartu SD dalam format CSV. Kalibrasi dilakukan dengan regresi linear terhadap alat referensi, menghasilkan akurasi 98,90%, 98,89%, 95,20%, dan 95,71%, dengan rata-rata 97,68% dan error relatif 2,32%. Pengujian efisiensi menunjukkan penurunan waktu pencatatan dari rata rata 349,5 detik menjadi 83,4 detik atau 3,85 kali lebih cepat, tanpa menurunkan ketelitian, dengan nilai RMSE suhu ±0,42 °C, kelembapan ruangan sebesarr ±0,91%RH, intensitas cahaya ruangan sebesar ±14,1 lux, dan suhu keluaran AC sebesar ±1,14 °C, seluruhnya berada di bawah ambang toleransi teknis. Alat ini terbukti menghemat waktu dan akurasi audit energi secara signifikan, serta berpotensi direplikasi untuk mendukung konservasi energi dan keberlanjutan sistem audit lingkungan di kota-kota lain di Indonesia.

Energy consumption in the building sector in Indonesia accounts for up to 40% of total annual energy, with air conditioning (AC) systems consuming 50–60% and lighting systems consuming around 7–8.56% of total building electricity. This situation strains the national power grid and increases greenhouse gas emissions. Energy audits are a strategic step in energy conservation, but the Surabaya City Environmental Agency's environmental data collection remains conventional, using three separate measuring devices and manual recording, resulting in the audit process for 31 sub-district offices and 160 villages taking up to 66 days and being prone to recording errors. This study designed and built an integrated environmental measurement device based on Arduino Uno capable for measuring room temperature, humidity, light intensity, and AC output temperature. The system consists of AHT20, VEML7700, and MLX90614-DCI sensors, equipped with a real-time LCD display, data acquisition buttons, and automatic storage to an SD card in CSV format. Calibration was performed using linear regression against a reference instrument, yielding accuracies of 98.90%, 98.89%, 95.20%, and 95.71%, with an average of 97.68% and a relative error of 2.32%. Efficiency testing showed a reduction in recording time from an average of 349.5 seconds to 83.4 seconds, or 3.85 times faster, without compromising accuracy, with an RMSE of ±0.42 °C for temperature, ±0.91%RH for room humidity, ±14.1 lux for room light intensity, and AC output temperature of ±1.14 °C, all within technical tolerance limits. This device has proven to significantly save time and improve energy audit accuracy, and has the potential to be replicated to support energy conservation and the sustainability of environmental audit systems in other cities across Indonesia.
