Abstract

Increased global warming and awareness of the need to reduce greenhouse gas emissions have strengthened the focus on energy efficiency in various sectors, including the HVAC (Heating, Ventilation, and Air Conditioning) industry. In this context, the selection of air conditioning (AC) systems becomes crucial in providing thermal comfort. However, decisions regarding air conditioning systems are often complex as they involve considerations of energy efficiency, operational costs, system reliability, and environmental impact. To address this complexity, Complex Proportional Assessment (COPRAS) emerged as an effective multi-criteria analysis method. However, the application of COPRAS in determining AC system traffickers is still limited. This research explores the possible application of COPRAS in this context and identifies key factors to consider. The evaluation results show that Medan Elektronik and Citra Inovasi Prima are the top choices in the selection of AC system traffickers. This research is expected to contribute to the development of more sophisticated analysis methods in the HVAC industry as well as assist decision makers in selecting more appropriate and sustainable air conditioning systems.

Abstract

Penelitian ini bertujuan untuk mengembangkan sistem pakar berbasis metode Certainty Factor dalam mendeteksi kerusakan pada mesin Vibration Continuous Monitoring. Mesin ini digunakan untuk memantau getaran pada mesin industri, yang jika tidak terdeteksi dapat menyebabkan kerusakan lebih parah dan mengurangi efisiensi operasional. Metode Certainty Factor digunakan untuk mengukur tingkat kepastian dalam diagnosis kerusakan berdasarkan gejala yang terdeteksi. Penelitian ini melibatkan pengumpulan data melalui observasi, wawancara dengan ahli, dan studi literatur untuk membangun basis aturan dan menghitung nilai CF untuk setiap gejala. Hasil penelitian menunjukkan bahwa sistem pakar ini mampu mendeteksi kerusakan dengan tingkat kepastian yang tinggi, dengan beberapa jenis kerusakan memiliki nilai CF di atas 90%. Dengan menggunakan sistem ini, proses diagnosis kerusakan dapat dilakukan lebih cepat dan akurat, mengurangi ketergantungan pada kehadiran teknisi ahli dan mengoptimalkan pemeliharaan mesin. Penelitian ini memberikan kontribusi penting dalam penerapan kecerdasan buatan di bidang pemeliharaan mesin industri, yang dapat meningkatkan efisiensi dan mengurangi biaya operasional.
