      Abstract
      Penelitian ini bertujuan menganalisa produksi gas CH4 dan tingkat akurasi methane gas detector terhadap pengukuran dengan estimasi stoikiometri pada sapi perah berfistula dengan variasi imbangan pakan. Parameter yang diamati meliputi produksi CH4, dan karakteristik fermentasi. Rancangan penelitian yang digunakan adalah bujur sangkar latin 3×3 dengan perlakuan: P1 (60% hijauan+40% konsentrat), P2 (50% hijauan+50% konsentrat), dan P3 (40% hijauan+60% konsentrat). Analisis data dilakukan dengan analisis korelasi Pearson, ANOVA dan Duncan. Hasil yang didapat menunjukkan bahwa imbangan pakan tidak berpengaruh signifikan terhadap produksi CH4. Selain itu, ditemukan korelasi antara CH4 hasil pengukuran methane gas detector dengan CH4 estimasi, namun nilai korelasi cenderung lemah dengan nilai Pearson’s r -0,49 dan nilai koefisien determinasi (R2) 0,24. Dapat disimpulkan bahwa imbangan pakan yang diberikan tidak memengaruhi produksi CH4 sapi perah berfistula dan methane gas detector belum dapat menggantikan metode estimasi stoikiometri.
       
      This study aims to analyze CH4 production and the accuracy level of CH4 measured by a methane gas detector against stoichiometric estimation method in dairy cattle with various feed balances. The parameters observed included CH4 production, and fermentation characteristic. The research design used was a 3×3 Latin square with treatments namely: P1 (60% forage+40% concentrate), P2 (50% forage+50% concentrate), dan P3 (40% forage+60% concentrate). Data analyzed using Pearson correlation analysis, ANOVA, and Duncan. The results obtained showed that the provision of feed balance did not significantly affect CH4 production. In addition, a correlation was found between CH4 measured by the device and estimated CH4, but the correlation value tended to be weak, namely with Pearson’s r value of -0.49 and coefficient of determination (R2) value of 0.24. Can be concluded that feed balance given did not affect the fistulated cows CH4 production and methane gas detector could not substitute the stoichiometric estimation method yet.
