Growth of bacteria in the Simmental liquid semen is is the cause of the quality of liquid cement to be bad. The addition of antibiotics has been done to inhibit the growth of bacteria in the liquid semen. One of antibiotic that often used is penicillin. The addition of sweet orange essential oil is expected to further suppress the growth of bacteria because it contains antibacterial. The research objective was to determine the value of the percentage Membrane Integrity and Acrosome Integrity on Simmental liquid semen with the addition penicillin and sweet orange essential oil. The method used was experimental using Completely Randomized Design with 5 treatments and 5 replications. The treatment was addition 0%, 0,25%; 0.5%; 0.75% and 1% sweet orange essential oil on tris yolk and penicillin extender. The results showed that addition sweet orange essential oil and tris yolk and penicillin extender resulted the best percentage value of the Membrane Integrity and Acrosome Integrity in Simmental liquid semen was the addition of sweet orange essential oil 1%.

The purpose of this study was to know the quality of Boer liquid semen during storage by adding sweet orange essential oil and gentamicin into the tris yolkextender.The semenlongevity test was carried out by storing semen in a closed tube at room temperature and refrigerator, and evaluated motility and Viability every 3 hours at room temperature and 12 hours in refrigerator. The results showed that the characteristics of the liquid semen, with the addition of 1% of essential oils showed percentage of motility and Viability significantly higher than 0.5% and without the addition of essential oil, either stored at room temperature or in the refrigerator. This may be related to the content of essential oils of sweet orange peel containing flavonoids and antibacterials that are capable of maintaining liquid semen quality of Boer Goat.In addition, gentamicin contains antibacterials capable of suppressing the growth of bacteria which can damage and durabilitythe spermatozoa.Keywords: Boer Goat,Gentamicin, Liquid semen, Sweet orange

One of the causes a poor quality of liquid semen is increasing bacterial growth. The addition of sweet orange essential oil and penicillin in Simmental liquid semen is expected to improve the quality of liquid semen because it contains antibacterial. The purpose of this research is to know the value of the percentage of motility, viability and spermatozoa abnormalities in Simmental liquid semen with an addition of combination penicillin with sweet orange essential oil on tris yolk extender. The research hypothesis is the addition of combination penicillin with sweet orange essential oil to tris yolk extender can increase the value of the percentage of motility, viability and spermatozoa abnormalities in Simmental liquid semen. Materials used in this study is the Simmental fresh semen, tris yolk extender, penicillin, and sweet orange essential oil. The experimental design used randomized design with 5 treatments and 5 replications. Treatment on the research is the addition of sweet orange essential oil 0%, 0.25%, 0.5%, 0.75% and 1%. The parameters observed were the evaluation of motility, viability and abnormality spermatozoa before equilibration and after equilibration. The results showed the best result was the addition of 1% sweet orange essential oil and the lowest on the addition of 0% sweet orange essential oil before and after equilibration.

The income analysis function is to measure the success or failure of business activity, find the main components of income, and whether that component can still be improved or not. This study aims to analyze the income of beef cattle fattening business in West Binjai District, Indonesia.
