Abstract

Cryoprotectant is one of determining factors for the success of stallion semen cryopreservation. Formost mammalian sperm cryopreservation,glycerol has been widely used as the cryoprotectant. Glycerol inhigh concentration is toxic to the sperm but in low concentration it has protective effect on the semen. Theobjectives of this experiment were to find appropiate glycerol concentration by using skim milk extender inorder to maintain motility and viability of spermatozoa of stallion frozen semen. Semen was collectedfrom three sexually mature stallions by using artificial vagina. The semen characteristics and qualitywere examined both macro and microscopically. Prior to extension, semen was centrifugated at 3000 rpmfor 15 minutes. The pellet was re-extended with skim milk extender with glycerol 5% (G5) 7.5% (G7.5), and10% (G10). The extended semen as then packed in mini straw (0.3ml), equilibrated at 5 oC for 2 hours,frozen in the liquid N2 vapor for15 minutes and then stored in liquid N2 container until futher evaluation.The frozen semen, was thawed at 37 oC for 30 seconds. The percentages of sperm motility and viabilitywere examihed. The result of this research showed that the sperm motility and viability in G5 was (23.8 %;35.6 %) significantly hihger (P<0.05) as compare a with G7.5 (18.1%; 28.6%) and G10. (11.8%; 23.1%). Therecovery Rate in G5 (35.4%) was significant high er (P<0.05) than G7.5 (26.9%) and G10 (17.6%). In conclusion,glicerol of 5% is recomended for cryopreservation of stallion semen extended with skim milk.

Abstract

BPR memiliki peranan penting dalam menjaga stabilitas keuangan. Dimana sasaran nasabahnya merupakan sektor riil yang akan mengalami pertumbuhan apabila perkreditan yang diberikan oleh BPR tersalurkan secara merata.Dilandasi fakta bahwa terdapat pertumbuhanpenyaluran kredit oleh BPR, bahkan pada tahun 2022 angka penyaluran kredit semakin bertumbuh 11.35%dibandingkan pada tahun 2021. Sehingga, penelitian ini dilakukan untuk melihat pengaruh dari kinerja keuangan berupa rasio likuiditas yang di wakili oleh variabel LDR (Loan to Deposit Ratio)dan rasio kredit oleh NPL (Non-Performing Loan) terhadap profitabilitas dengan variabel yang digunakan ialah ROA (Return on Asset) pada tahun 2017-2022 untuk BPR di Indonesia dengan menggunakan metode Analisis Regresi Linear Berganda. Berdasarkan analisis tersebut, didapatkan bahwa LDR dan NPL, serta LDR dan ROA,memiliki hubungan yang positif dengan kategori sangat lemah. Namun untuk NPL dan ROA memiliki hubungan negatif yang kuat. Selain itu juga didapatkanmodel regresi, dimana model tersebut menjelaskan variabel LDR dan NPL secara bersama-sama signifikan terhadap ROA, namun pengaruh paling signifikan terhadap ROA adalah variabel LDR, yaitu rasio kredit yang bermasalah.Sebesar 63.23% nilai-nilai dari variabel ROA mampudijelaskan oleh LDR dan NPL dalam model.
