Abstract

This study aimed to examine the effect of time differences on motility, viability, abnormality, and intact plasma membrane of spermatozoa of Sapera goats before freezing. This study used a Completely Randomized Design (CRD) with three settings, namely the equilibration time P1 (1 h), P2 (3 h), and P3 (4 h), each of six replications. The results of motility using One Way Anova statistical analysis through the Duncan Test were (P1) 71.50 ± 3.94, (P2) 66.00 ± 2.60, and (P3) 60.33 ± 2.42. The results of viability was (P1) 83.00 ± 6.16, (P2) 75.17 ± 4.70, and (P3) 69.00 ± 3.40. Abnormal results was (P1) 2.50 ± 0.55, (P2) 3.33 ± 1.18, and (P3) 6.50 ± 2.88. While the results of intact plasma membranes were (P1) 79.50 ± 8.50, (P2) 72.67 ± 5.28, and (P3) 65.67 ± 3.78. The conclusion of the study showed significant significant results (p<0,05) between the equilibration time and spermatozoa quality of Sapera goats before freezing. The highest presentation of motility, viability and overall plasma membrane was at an equilibration time of 1 h, while the lowest abnormality presentation was at equilibration time of 1 h.

Abstract

The reason for this research is to test the effects of financial ratios such as Current Ratio, Debt to Equity Ratio, SIZE, and Return on Equity on the financial work of companies listed on the IDX in 2021-2022. Current Ratio, Debt to Equity Ratio, Return on Equity and SIZE as independent variables are used in this study, with ROA as the dependent variable. The population in this study is coal companies listed on the IDX in 2021-2022 using participants as many as 60 companies. The technique used in this study is known as purposive sampling (the process of determining the sample based on certain conditions). The type of information utilized in his research is secondary information obtained on the Indonesia Stock Exchange (IDX) for 2021-2022. The results of this study show that the Current Ratio has a positive insignificant impact on financial performance, the Debt to Equity Ratio variable has a negative insignificant impact on financial performance, the Return On Equity variable has a significant positive impact on financial performance and the SIZE variable has a positive insignificant impact on financial performance.
