Abstract

Penelitian ini mengkaji penerapan model pembelajaran mesin untuk mengklasifikasikan perilaku ayam pada kondisi suhu dan kelembapan yang bervariasi, dengan tujuan mengoptimalkan kesejahteraan dan produktivitas unggas melalui pemantauan otomatis. Analisis difokuskan pada perilaku utama seperti Beristirahat, Makan/Minum, dan Aktivitas Fisik, serta meneliti bagaimana fluktuasi lingkungan memengaruhi respons fisiologis ayam, khususnya dalam termoregulasi. Selama periode pengamatan selama 21 hari, data dikumpulkan dari enam ayam menggunakan sensor suhu dan kelembapan, disertai dengan rekaman video. Sebanyak lima model pembelajaran mesin diuji, yaitu Random Forest, Support Vector Machine (SVM), K-Nearest Neighbors (KNN), Multi-Layer Perceptron (MLP), dan metode ensemble, untuk mengidentifikasi model yang paling efektif di antara lima model yang digunakan. Model Random Forest menunjukkan kinerja terbaik dengan akurasi sebesar 98,65%, membuktikan kemampuannya dalam membedakan berbagai aktivitas dengan efektif. Selain itu, temuan penelitian ini menekankan pentingnya mengintegrasikan data lingkungan secara real-time dan meningkatkan teknik ekstraksi fitur untuk meningkatkan keandalan klasifikasi. Wawasan dari penelitian ini berpotensi memberikan kontribusi terhadap pengembangan sistem pemantauan cerdas adaptif, meskipun masih memerlukan validasi lebih lanjut dengan jumlah sampel yang lebih besar, sekaligus menjadi landasan awal yang berpotensi mendukung kemajuan di masa depan dalam manajemen unggas komersial dengan memungkinkan intervensi kesejahteraan yang tepat waktu dan mendukung operasi yang efisien serta berorientasi pada kesejahteraan.

Abstract

This study aims to analyze the effect of oxygen absorber on the color stability of gelamai. It evaluates changes in chroma and hue angle using the CIE Lab color system under two types of packaging (PE and vacuum) and two storage temperatures (room temperature and freezer) during 8 days. The colour changes observed in the samples were caused by oxidation. Throughout storage, the oxygen absorber reduces or retardes oxidative reactions. These findings revealed that vacuum packaging slowed colour changes more effectively than PE packaging, especially at room temperature, while freezer storage produced more complex and nonlinear patterns, likely due to physicochemical interactions. Kinetic analysis disclosed a difference in reaction rate constants (k) between packaging and temperature conditions, vacuum packaging disclosed lower kinetic value and more stable color than other conditions. PE room temp (R² = 0.9311), Vacuum room temp (R² = 0.5776), PE freezer (R² = 0.5847), Vacuum freezer (R² = 0.7258). Statistically disclosed no significant difference in all treatments. This study concludes that oxygen absorbers are effective in preserving the color quality of gelamai during storage.
