Abstract
Penelitian ini mengkaji keandalan sistem deteksi gas karbon dioksida (CO2) yang esensial untuk mengoptimalkan pertumbuhan tanaman di greenhouse. Namun, tantangan seperti ketidakstabilan kinerja sensor akibat faktor eksternal sering menghambat akurasi data. Tujuan utama penelitian ini adalah mengkarakterisasi kinerja sensor CDM-4160 dan MQ-135 dalam mendeteksi gas CO2, menganalisis tingkat keandalannya, serta menerapkan penilaian Risk Priority Number (RPN) untuk mengidentifikasi risiko kegagalan sistem. Metode penelitian mencakup perancangan perangkat keras dan lunak, kalibrasi sensor, pengujian performa di bawah variasi suhu dan kelembapan dalam chamber terkontrol, serta analisis data menggunakan Failure Mode Effect and Critically Analysis (FMECA). Hasil penelitian menunjukkan bahwa sensor CDM-4160 memiliki stabilitas dan akurasi tinggi dengan R2=0.984 dalam karakterisasi, serta tingkat keandalan 95.8% dan 92.06% pada uji temperatur dan kelembapan. Sementara sensor MQ-135, menunjukkan fluktuasi signifikan dengan nilai R2=0.974 dalam karakterisasi, dengan tingkat keandalan 77.88% dan 100% pada uji temperatur dan kelembapan. Analisis RPN menunjukkan Adaptor 5V sebagai komponen paling kritis, disusul oleh kedua sensor gas yang menyumbang 40% dari total kegagalan. Meskipun begitu, MQ-135 tetap dapat dijadikan alternatif ekonomis dengan kalibrasi yang tepat dan pengendalian lingkungan yang ketat. Implikasi dari penelitian ini memberikan kontribusi praktis terhadap strategi pemeliharaan berbasis keandalan pada sistem deteksi gas, serta mendorong pemanfaatan sensor low-cost yang lebih efisien.

This study investigates the reliability of a carbon dioxide (CO₂) detection system, which is essential for optimizing plant growth in greenhouse environments. However, challenges such as sensor performance instability due to external factors often hinder data accuracy. The primary objectives of this research are to characterize the performance of the CDM-4160 and MQ-135 sensors in detecting CO₂ gas, assess their reliability levels, and apply the Risk Priority Number (RPN) evaluation to identify potential failure risks within the system. The research methodology involves the design of both hardware and software components, sensor calibration, performance testing under varying temperature and humidity conditions in a controlled chamber, and data analysis using Failure Mode, Effects, and Criticality Analysis (FMECA). The results reveal that the CDM-4160 sensor exhibits high stability and accuracy, achieving an R² value of 0.984 during characterization, with reliability rates of 95.8% and 92.06% in temperature and humidity tests, respectively. In contrast, the MQ-135 sensor displays significant fluctuations, with an R² value of 0.974, and reliability levels of 77.88% and 100% in the same tests. RPN analysis identifies the 5V Adapter as the most critical component, followed by the two gas sensors, which together account for 40% of total system failures. Despite this, the MQ-135 sensor remains a viable low-cost alternative if it undergoes proper calibration and is operated under tightly controlled environmental conditions. The implications of this study offer practical contributions to reliability-centered maintenance strategies in gas detection systems and encourage the use of more efficient, low-cost sensor solutions.
