The variables observed included Respondent Characteristics, Service Per Conception (S/C), and Conception Rate (CR). From the results of the study, it can be concluded that Service per Conception (S/C) was recorded at 1.32. High S/C values tend to cause longer birth intervals compared to livestock that have normal birth intervals of 12 months. In addition, the Conception Rate (CR) obtained in this study reached 75.3%, which is in accordance with the ideal standard (CR) of cattle ranging from 60-75%, where the higher the CR value, the better the fertility rate of the livestock.

Analisis Nilai Guna dan Efektifitas Faktor Produksi Fibers Polyester di PT. QRS melalui Perbandingan Hasil Aktual dan Perhitungan
Get PDFIn the industrial era 4.0, most of the production processes use automatic machines. However, not a few companies still carry out their production processes manually, for this reason it is necessary to carry out an analysis of the value of effectiveness and efficiency between the workforce and also the machines so that production runs well 0020GHIn writing this data and information obtained through interviews, observation, and documentation. This research uses descriptive method using a quantitative approach. Effective capacity of labor 1515.2. Whereas the effective capacity of the extruder machine is 378.8, the labor factor has not yet shown the maximum figure because it has not reached 100%. This can be seen from the average efficiency which only reaches 25%, while the efficiency of using extruder machines is maximized with the results of calculating an average efficiency of 100% per month, suggestions that explain the efficiency of the use of labor and machines. The results of the author\u27s research at PT. QRS revealed that the condition of the low level of efficiency in the labor factor needs to be reviewed regarding the operation of the extruder machine which is still manual for the input of production raw materials. The efficiency of using the extruder machine at PT.QRS is already very good, it\u27s just a matter of maintaining it.
