The variables observed in this study included color, aroma, texture and taste of beef <em>Se’i</em>. The data obtained were analyzed statistically with a nonparametric alternative test, namely Kruskal Wallis. If the Kruskal Wallis test showed a significant difference (p&lt;0.05), then it was continued with the Post Hoc Test using the Mann Whitney test. Panelists responded to the color of beef <em>Se’i</em> best in the addition of 30 mL of <em>Schleichera oleosa</em> bark extract with an average value of 4.37. Beef <em>Se’i</em> with the addition of <em>Schleichera oleosa</em> bark extract produces a reddish color compared to <em>Se’i</em> without the addition of <em>Schleichera oleosa</em> bark extract which has a more blackish color. The best beef <em>Se’i</em> aroma was shown in the addition of 40 mL of <em>Schleichera oleosa</em> bark extract at 5.30 followed by the addition of 30 mL and 20 mL of extract. 30 mL of <em>Schleichera oleosa</em> bark extract provides a distinctive taste that is favored by panelists. The best taste of beef <em>Se’i</em> in the addition of 30 mL of <em>Schleichera oleosa</em> bark extract was 4,70 followed by the addition of 20 mL of <em>Schleichera oleosa</em> bark extract, which had a second average of 4.50 and 40 mL, which was 4.16. Meanwhile, the lowest mean value was in the treatment without the addition of <em>Schleichera oleosa</em> bark extract, which was 4.00. Panelists assessed the best texture of beef <em>Se’i</em> produced in the addition of 30 mL of <em>Schleichera oleosa</em> bark extract, which was 5.26. <em>Se’i</em> beef with the addition of 40 mL of <em>Schleichera oleosa</em> bark extract had a second average of 5.23 and 20 mL, which was 4.50. Meanwhile, beef <em>Se’i</em> without the addition of <em>Schleichera oleosa</em> bark extract had the lowest average of 4.06.</p> Aristo Kurniawan Sio, Irma Isnafiah Arief, Tuti Suryati ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://jurnal.unimor.ac.id/JTAST/article/view/2481 Mon, 08 Aug 2022 12:45:14 +0000 Comparison of Quality Physicochemical Longissimus Dorsi Mucsle of Ongole Crossbred Culled Cow Beef and Bali Culled Cow Beef https://jurnal.unimor.ac.id/JTAST/article/view/2800 <p>Each meat of the breed has different quality of physicall and chemicall, they are several factors that influence it, one of them is age factor.

The experimental design applied was completely randomized design (CRD) with 4 treatments and 3 replications.The treatments consisted of &nbsp;R<sub>0</sub>= without rosella flour, R<sub>1</sub>= 5% rosella flour, R<sub>2</sub>= 10% rosella flour and R<sub>3</sub>= 15% rosella flour. Parameters observed included color, taste and fat oxidation. The result of statistical analysis showed that the use of rosella flour in pork jerky had a very significant effect (P&lt;0.01) on taste scores and fat oxidation but no significant effect (P&gt;0.05) on color scores. It can be concluded that the use of rosella flour can increase the score of taste and fat oxidation while the color score of pork jerky does not change. The highest taste score at the 15% level and the lowest fat oxidation value at the 5% level.</p> Yakob Robert Noach, Geertruida Margareth Sipahelut, Heri Armadianto, Agustinus Ridolf Riwu, Agustina Mariana Kumat ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://jurnal.unimor.ac.id/JTAST/article/view/2662 Tue, 09 Aug 2022 13:59:27 +0000 Effect of Defoliation Age on The Production and Energy Value of Indian Bluegrass (Bothriochloa pertusa) https://jurnal.unimor.ac.id/JTAST/article/view/2508 <p>The purpose of this experiment was to evaluate the herbage production and energy value of Suket putihan grass (<em>Bothriochloa pertusa</em>) harvested at different ages. The experiment was carried out following a completely randomize design with 3 treatments and 3 replications. The treatments consisted of different defoliation ages of Suket putihan grass (<em>Bothriochloa pertusa</em>), i.e. respectively at 40 days (BP<sub>40</sub>), 60 days (BP<sub>60</sub>), 80 days (BP<sub>80</sub>). The observed variables included the dry matter (DM) production, stem leaf ratio, <em>In vitro </em>digestibillity and energy value. Result showed that the defoliaton age had a significant effect (P&lt;0.05) on dry matter production, stem leaf ratio, dry matter digestibillity and had a very significant effect (P&lt;0.01) on the organic matter digestibillity and energy value of Suket putihan grass (<em>Bothriochloa pertusa</em>). The DM production of Suket Putihan grass (<em>Bothriochloa pertusa</em>) increased with increasing defoliation age, while its In vitro digestibility and energy value decreased due to the high stem to leaf ratio and increased harvesting time. In conclusion, the best defoliation time for <em>B. pertusa</em> is between 40 and 60 days after planting.</p> I Gusti Ngurah Jelantik, Kristina Bedinan, Imanuel Benu ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://jurnal.unimor.ac.id/JTAST/article/view/2508 Tue, 09 Aug 2022 00:00:00 +0000 Effect of The Inclusion of Butterfly Pea (Clitoria ternatea) and Green Sea Weed (Ulva lactuca) in The Complete Feed on The Concentration of Blood Metabolites of Male Kacang Goats https://jurnal.unimor.ac.id/JTAST/article/view/2524 <p>This experiment aimed to investigate the effect of including&nbsp; <em>C</em><em>litoria</em><em> ternatea</em> and <em>Ulva lactuca</em> in the complete feed on the concentration of blood metabolites of male kacang goats. Four male kacang goats were involved in this experiment arranged following a Latin Square Design with 4 treatments and 4 periods as replication. The treatments were R0= native grass hay 60%+concentrate 40%, R1= native grass hay 30%+concentrate 40%+ <em>Clitoria ternatea</em> 30%, R<sub>2</sub>= native grass hay 30%+concentrate 40%+ <em>Clitoria ternatea</em> 15%+ Ulva lactuca 15% and R<sub>3</sub>= native grass hay 30%+ concentrate 40%+<em>Ulva lactuca</em> 30%. Data were analyzed using analysis of variance (ANOVA) and followed by the Duncan Multiple Range Test when significant differences were found. The results showed that&nbsp; feeding a complete feed containing&nbsp; <em>Clitoria ternatea</em> and <em>Ulva lactuca</em> did not significantly (P&gt;0,05) affect the concentration of urea, glucose and &nbsp;plasm total protein in the blood of male kacang goats. Therefore, it can be concluded the inclusion of <em>Clitoria ternatea</em> and <em>Ulva lactuca</em> has no effect on the concentration of blood metabolites in male kacang goats.</p> I Gusti Ngurah Jelantik, Wigberta N.

This study used 3 cull Onggole cows (BW range 194-210.5 kg) aged 8-9 years. The experiment was conducted following the Latin Square Design (LSD) with 3 treatments and 3 periods as replication. The treatments were basal feed and supplemented with <em>Acacia nilotica</em> fruit at a level of 0% (BAN0), 0.5% (BAN0.5), 1% (BAN1) of the animal's body weight respectively. The results showed that supplementation of <em>Acacia nilotica</em> fruit up to 1% of body weight increased (P&lt;0.01) the intake of DM and OM. Meanwhile, the supplementation of <em>A. nilotica</em> at 1% BW increased the digestibility of DM but had no effect on the digestibility of OM. The conclusion of the study was that the supplementation of black kabesak fruit (<em>Acacia nilotica</em>) up to a level of 1% BB could be beneficial in increasing the intake of DM and OM and the digestibility of DM in cull Onggole cows.</p> I Gusti Ngurah Jelantik, Robertus A.

Ferns fermented with molasses and starbio to determine nutrient content, in vitro dry matter digestibility (IVDMD) and in vitro organic matter digestibility (IVOMD). This research method uses a completely randomized design (CRD) with four treatments and three replications. The feed treatments were P0 (control): 100% fermented paku resam, P1= P0 + 2% molasses + 2% starbio, P2= P0 + 2% molasses + 4% starbio, and P3 = P0 + 2% molasses + 6% starbio. The parameters of this study were physical quality, feed nutrients, IVDMD and IVOMD. The results showed that the physical quality of all treatments was brown, smelled, and had a hard texture. Nutrients of ferns contain P0= (CP 10.79%, TDN 60.8%), P1= (CP 10.41%, TDN 65.78%), P2= (CP 13%, TDN 68.54%), and P4= (CP 10.90%, TDN 61.14%). The results of IVDMD showed a change (P&lt;0.05) in each fermentation treatment, the highest in P2 of 21.13% or an increase of 40.68% compared to control (15.02%), then in P3 of 18.25% or an increase of 21.5% , and in P1 by 18.2% or an increase of 21.17%. The results of IVOMD showed a change (P&lt;0.05), the highest in P2 of 17.2% or an increase of 12.79% compared to control (15.25%), in P1 of 15.49% or an increase of 1.57%, will but in P3 it was 14.62% decreased by 4.13%. The conclusion of this research is the addition of molasses and starbio to fermented feed increases the digestibility of dry matter and organic matter to the level of molasses 2% + starbio 4%. However, as a ruminant feed ingredient, ferns have a low digestibility.</p> Ida Ketut Mudhita, Asih Pujiastuti, Bambang Dedy Harsono ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 https://jurnal.unimor.ac.id/JTAST/article/view/3029 Tue, 09 Aug 2022 00:00:00 +0000
