Abstract:
This study aims to determine the quality of forage ferns (Gleichenia linearis) as animal feed for ruminants in West Kotawaringin Regency, Central Kalimantan. 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<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<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.

Abstract:
This reseach aims to examine the effect of using rosella flour (Hibiscus sabdariffa Linn) on the chemical and organoleptic qualities of pork jerky. The materials used consist of pork, rosella flour and kitchen spices (garlic, onion, coriander, pepper, ginger, cumin, galangal, salt, brown sugar, granulated sugar and tamarind). The experimental design applied was completely randomized design (CRD) with 4 treatments and 3 replications.The treatments consisted of R0= without rosella flour, R1= 5% rosella flour, R2= 10% rosella flour and R3= 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 (P0.05) 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.

Abstract:
The purpose of this experiment was to evaluate the herbage production and energy value of Suket putihan grass (Bothriochloa pertusa) 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 (Bothriochloa pertusa), i.e. respectively at 40 days (BP40), 60 days (BP60), 80 days (BP80). The observed variables included the dry matter (DM) production, stem leaf ratio, In vitro digestibillity and energy value. Result showed that the defoliaton age had a significant effect (P<0.05) on dry matter production, stem leaf ratio, dry matter digestibillity and had a very significant effect (P<0.01) on the organic matter digestibillity and energy value of Suket putihan grass (Bothriochloa pertusa). The DM production of Suket Putihan grass (Bothriochloa pertusa) 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 B. pertusa is between 40 and 60 days after planting.

Abstract:
This experiment aimed to investigate the effect of including Clitoria ternatea and Ulva lactuca 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%+ Clitoria ternatea 30%, R2= native grass hay 30%+concentrate 40%+ Clitoria ternatea 15%+ Ulva lactuca 15% and R3= native grass hay 30%+ concentrate 40%+Ulva lactuca 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 feeding a complete feed containing Clitoria ternatea and Ulva lactuca did not significantly (P>0,05) affect the concentration of urea, glucose and plasm total protein in the blood of male kacang goats. Therefore, it can be concluded the inclusion of Clitoria ternatea and Ulva lactuca has no effect on the concentration of blood metabolites in male kacang goats.

Abstract:
This study aims to determine the organoleptic quality of beef Se’i which was given Schleichera oleosa bark extract at different levels. Se’i beef was processed by adding 0 mL of Schleichera oleosa bark extract (without the addition of extract), 20 mL, 30 mL and 40 mL, then the beef Se’i was smoked in a smoker house for ± 1 hour at a temperature of 80-90˚C. Se’i beef was then tested by 30 semi-trained panelists who were panelists who often consumed beef Se’i. The variables observed in this study included color, aroma, texture and taste of beef Se’i. The data obtained were analyzed statistically with a nonparametric alternative test, namely Kruskal Wallis. If the Kruskal Wallis test showed a significant difference (p<0.05), then it was continued with the Post Hoc Test using the Mann Whitney test. Panelists responded to the color of beef Se’i best in the addition of 30 mL of Schleichera oleosa bark extract with an average value of 4.37. Beef Se’i with the addition of Schleichera oleosa bark extract produces a reddish color compared to Se’i without the addition of Schleichera oleosa bark extract which has a more blackish color. The best beef Se’i aroma was shown in the addition of 40 mL of Schleichera oleosa bark extract at 5.30 followed by the addition of 30 mL and 20 mL of extract. 30 mL of Schleichera oleosa bark extract provides a distinctive taste that is favored by panelists. The best taste of beef Se’i in the addition of 30 mL of Schleichera oleosa bark extract was 4,70 followed by the addition of 20 mL of Schleichera oleosa 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 Schleichera oleosa bark extract, which was 4.00. Panelists assessed the best texture of beef Se’i produced in the addition of 30 mL of Schleichera oleosa bark extract, which was 5.26. Se’i beef with the addition of 40 mL of Schleichera oleosa bark extract had a second average of 5.23 and 20 mL, which was 4.50. Meanwhile, beef Se’i without the addition of Schleichera oleosa bark extract had the lowest average of 4.06.
