The research took place in September 2020 in Noenebu, Tapenpah Village, Insana District, North Central Timor Regency, and the Laboratory of the Faculty of Agriculture, University of Timor. This study used a completely randomized design (CRD) with 4 treatments and 5 replications. &nbsp;Treatment R1&nbsp;consist of 10% tris solution, 10% olive oil, 80% semen;&nbsp;R2 treatment consist of 15% tris solution, 15% olive oil, 70% semen;&nbsp;R3 treatment consist of 20% tris solution, 20% olive oil, 60% semen, and R4 treatment consist of 25% tris solution, 25% olive oil, 50% semen. The results showed that the effect of different treatments was very significant (P &lt;0.01) on the viability of spermatozoa. The mean spermatozoa viability of each treatment was R1 of 89 ± 2.57%, R2 of 76.9 ± 12.51%, R3 of 62.8 ± 3.11%, and R4 treatment of 41.2 ±&nbsp;15, 38%. The spermatozoa abnormalities were significantly different (P &lt;0.05). Where the abnormality of the spermatozoa in treatment R1 was 8.8 ± 1.30%, R2 was 10.4 ± 1.67%, R3 was 11.6 ± 1.81%, and R4 was 14.4 ± 3.78%. The degree of acidity (pH) of the semen&nbsp;was not significantly different between treatments. The pH value of each treatment was R1 of 7.92 ± 0.83, R2 of 8.04 ± 0.54, R3 of 7.96 ± 0.39; and R4 treatment of 8.06 ± 0.64. It can be concluded that the addition of 10% to 20% olive oil can maintain the viability and abnormality of duroc boar male spermatozoa. However, the use of olive oil up to 20% does not affect to degree of acidity of the semen&nbsp;produced.</p> <p>&nbsp;</p> <p><strong><em>&nbsp;</em></strong></p> 2021-08-22T20:29:49+00:00 ##submission.copyrightStatement## https://jurnal.unimor.ac.id/JTAST/article/view/1205 Effect of Calcium Level in Feed on Blood Profile of Broiler Chicken 2021-08-23T02:56:52+00:00 Modesta Salu deamikaelsalu@gmail.com Charles Venirius Lisnahan charleslisnahan@yahoo.co.id Oktovianus R. Nahak oktovianusrafael@yahoo.co.id <p>This study aims to determine the effect of calcium supplementation in feed on the blood profile of broilers chickens. This research was conducted in a broiler chicken coop, owned by breeders in Sasi Village, Kefamenanu City &nbsp;District, North Central East District. This research was conducted from July to August 2020. This study used 96 broilers. The method used in this was a completely randomized design consisting of 4 replications and 4 treatments. The treatments given were T<sub>0 </sub>(control diet), T<sub>1</sub>&nbsp;(calcium supplementation 1,00 %), T<sub>2</sub>&nbsp;(calcium supplementation 1,50 %), T<sub>3</sub>&nbsp;(calcium supplementation 2,00 %). The variables observed in this study were the content of erythrocytes, hemoglobin, and blood leucocytes. The data obtained were analyzed using analysis of variance. Analysis of variance showed that the treatment had no significant effect on erythrocytes, hemoglobin, and leucocytes of broiler chickens. It was concluded that the addition of calcium in feed at different levels did not increase the content of erythrocytes, hemoglobin, and leucocytes of broiler chickens aged 6 weeks.</p> 2021-08-22T20:36:21+00:00 ##submission.copyrightStatement## https://jurnal.unimor.ac.id/JTAST/article/view/1032 Motility, Viability, Spermatozoa Abnormality, and pH of Bali Cattle Semen in Another-Yellow Water Driller Stored in a Different Time 2021-08-23T02:56:53+00:00 Fransiskus X. Manehat ferrymanehat@gmail.com Agustinus Agung Dethan agungdethan@yahoo.com Paulus Klau Tahuk paulklau@yahoo.co.id <p>This study aims to determine the quality of Bali cattle spermatozoa diluted using sugarcane juice-egg yolk. This research was carried out in the stables and Laboratory of the Faculty of Agriculture, University of Timor in August-September 2020. Semen was collected from an adult male bali cattle, aged ± 4.5 years in healthy condition. The method used in this study is an experimental method using a completely randomized design consisting of 4 treatments and 5 replications. Each treatment was T1: 0.075 ml semen&nbsp;+ 0.3 ml of egg yolk sugarcane juice diluent and stored for 24 hours, T2: semen&nbsp;0.075 ml + 0.3 ml of diluent for egg yolk cane juice and stored for 48 hours, T3: semen&nbsp;0.075 ml + 0.3 ml of diluent for egg yolk sugarcane juice and stored for 72 hours, T4: semen&nbsp;0.075 ml + 0 ,3 ml of egg yolk sugarcane juice diluent and stored for 96 hours. The variables measured were individual motility, viability, spermatozoa abnormalities, and semen pH. The results showed that the T4 treatment on a shelf life of 96 hours still showed a good average value with individual spermatozoa motility values of 45%, spermatozoa viability of 77.3%, spermatozoa abnormalities of 12.5% and semen pH 6.6. It can be concluded that the use of cane juice-egg yolk diluent has a positive impact because it is able to maintain the viability of spermatozoa for 96 hours.</p> <p>&nbsp;</p> <p>&nbsp;</p> 2021-08-22T20:39:57+00:00 ##submission.copyrightStatement## https://jurnal.unimor.ac.id/JTAST/article/view/1170 Performance Analysis and Added Value of Industry Processing Beef into Processed Meat Jengken and Shredded in the Kota Kefamenanu District 2021-08-23T02:56:53+00:00 VICTORIA SARI LAU sarilau76@gmail.com Stefanus Sio siostefanus@yahoo.com Theresia Ika Purwatiningsih theresiaicha@gmail.com Hilarius Y.

The semen used is in the form of fresh semen from 2-year-old duroc pigs. Semen was collected by a manual method using artificial broodstock. This research was conducted in November 2020 using an experimental method according to the Completely Randomized Design (CRD) procedure with 4&nbsp;treatments and 4&nbsp;replications so that there were 16 experimental units. Each treatment is P0: storage of semen for 0 hours, P1: storage of semen for 24 hours, P2: storage of semen for 36 hours, P3: storage of semen for 48 hours. The results showed that the use of tris-egg yolk-coconut water diluent had a significant effect (P &lt;0.05) on&nbsp;viability, abnormality, and degree of acidity (pH). The mean value of spermatozoa viability was P0: 96%, P1: 93.75%, P2: 84.5%, and treatment P3: 79.5%. The mean value of spermatozoa abnormality in treatment P0: 5.25%, P1: 6.5%, P2: 11.25%, and treatment P3: 14.75%. The average value of the degree of acidity (pH) of semen&nbsp;P0: 8.3 P1: 7.2; P2 7,3 and P3 treatment: 7,25. It can be concluded that the dilution of semen using tris-egg yolk and coconut water can maintain the value of viability, abnormalities of spermatozoa, and degree of acidity (pH).</p> <p>&nbsp;</p> 2021-08-22T00:00:00+00:00 ##submission.copyrightStatement##
