SISTEM INFORMASI DETEKSI DINI BAHAYA GAS AMONIA (NH3) PADA LINGKUNGAN PETERNAKAN MENGGUNAKAN METODE INVERSE DISTANCE WEIGHT

Amonia merupakan salah satu gas yang dianggap berbahaya di lingkungan peternakan, khususnya di peternakan unggas. Peningkatan konsentrasi gas amonia di kandang unggas dapat menyebabkan keracunan bahkan kematian unggas ketika mencapai kadar konsentrasi tertentu. Oleh karena itu diperlukan analisis yang tepat dan cepat untuk mengurangi angka kematian unggas yang disebabkan oleh gas amonia. Pada penelitian ini diusulkan sistem informasi yang mampu memantau kondisi kadar konsentrasi gas amonia secara realtime di lingkungan peternakan. Penelitian ini membangun sistem wireless system network yang mentransmisikan data ke web server melalui koneksi internet. Untuk menghitung kadar konsentrasi gas amonia penelitian ini mengusulkan metode interpolasi inverse distance weight sebagai metode komputasinya. Pengambilan data dilakukan di 3 titik lokasi sesuai dengan badan standarisasi nasional. Pengambilan data dilakukan dengan menggunakan sensor MQ-135. Dari penelitian ini dihasilkan sistem informasi yang mampu memantau kadar konsentrasi gas amonia secara realtime dan memberikan notifikasi efek bahaya sesuai kadar konsentrasi gas amonia di peternakan. Akurasi perhitungan metode yang digunakan menunjukan nilai MAPE sebesar 7,75%. Perubahan kadar konsentrasi gas amonia ditampilkan menggunakan visualisasi grafik di dashboard sistem informasi.Jika kondisi amonia berbahaya maka pesan bahaya dikirimkan melalui aplikasi sosial media pada smartphone dalam bentuk notifikasi ke pengguna. Kata kunci : amonia, peternakan, inverse distance weight, wireless sensor network, sosial media Ammonia is one of the gases that is considered dangerous in livestock environments, especially in poultry farms. Increasing the concentration of ammonia gas in poultry cages can cause poisoning and even death of poultry when it reaches a certain concentration level. Proper and fast analysis is needed to reduce poultry mortality caused by ammonia gas. Therefore in this study an information system was proposed which was able to monitor the condition of the concentration of ammonia gas in real time in the farm environment. This research builds a wireless system network system that transmits data to a web server through an internet connection. To calculate the concentration level of ammonia gas this study proposes an inverse distance weight interpolation method as its computational method. Data collection is carried out in 3 location points according to the national standardization body.Data is collected by using the MQ-135 sensors. From this research, an information system was produced which was able to monitor the concentration of ammonia gas in real time and provide a notification of the effects of hazards according to the concentration of ammonia gas at farms. The accuracy of the calculation method used shows the MAPE value of 7.75%.Changes in the concentration level of ammonia gas are displayed using graphical visualization on the information system dashboard. If the ammonia condition is dangerous, the hazard message is sent via the social media application on the smartphone in the form of notification to the user.
