Abstract

The study aims to analyze the quality of physical chemistry beef meatballs soaked in liquid smoke with different concentrations. Research conducted at the Laboratory of Livestock Product Technology and Microbiology, Faculty of Animal Husbandry Udayana University for two months, starting from January 30 to March 31, 2014. Liquid smoke is used from the village of Panti subdistrict Sukorambi, Jember, East Java. The meatballs were taken from the company meatballs are often consumed by the general population in Bali. The study design used completely randomized design (CRD) with five treatments and observed variables include moisture content, total acid, TBA value, phenol and water activity (?w). The results showed that the increase of liquid smoke concentration in soaking of beef meatballs could significantly increase (P<0,05) of total phenol from cow meatballs produced. The use of 2% concentration (P5) yields the highest phenol content (0.11%). Against the rancidity/Thiobarbituric Acid variables, the use of 1% liquid smoke concentration (P3) is capable of producing the lowest degree of rancidity (0.03%). While the other variables are water content, total acid and water activity, the use of different concentrations of liquid smoke, does not result in a significantly different value (P> 0.05). Based on the results of the research can be concluded the use of liquid smoke at a concentration of 1% capable of producing cow meatballs with the lowest rancidity. Keywords: Liquid Smoke, BeefMeatballs, Concentration, Quality

Abstract

The study aim to determine the effect of the natural fermentation of cow milk and goat milk to flavor (taste and aroma), total acid and protein concentration. The samples were fresh Frisian Holstein Crossbreed (FHC) cow milk, and Etawa Crossbreed (PE) goat milk. Those were obtained from CV. Margo Utomo, located at Pulau Batam Street, No.10, Denpasar and a distributor of fresh goat milk was UD. Bali Sariwangi, located at Sepang Village, Busungbiu, Buleleng, Bali. The experimental design used was Randomized Block Design (RBD) consisted of 2 factors and 3 replicated. The first factors were milk type, namely S1 (100% cow milk), S2 (50% cow milk+50% goat milk) and S3 (100% goat milk). The second factors were fermentation time, i.e. W0 (control), W10 (10 hours of fermentation) and W20 (20 hours of fermentation). The variables observed were: flavor (taste and aroma), total acid and protein concentration. The result showed that milk type was not significantly differen (P>0,05) on taste and aroma, while the total acid and protein concentration were significant differen (P<0,05). The fermentation time was significantly different (P<0,05) to taste, aroma, the total acid and protein concentration. The interaction between milk type and fermentation time was significantly differen (P<0,05) to taste whereas in aroma, total acid and protein concentration were not significantly diferen (P>0,05). Based on the result of the study, it can be concluded that the type of milk does not affected the taste and aroma of sour milk, but could increase total acid and reduce protein concentration during 20 hours fermentation. The fermentation time could increased total acid and reduce protein concentration, and reduce the score of panelis preference for taste and aroma of sour milk. There were interaction on taste. To make nature mixed milk and goat milk fermentation for 10 hours, due to it has no effect on taste and aroma, and total acid andprotein concentration is still in accordance with the standard, so it still suitable for consumsion and acceptable to consumers. Keywords: natural fermentation, cow milk, goat milk, total acid, protein, flavor.

Abstract

Penelitian mengenai pengaruh tingkat protein terhadap penampilan ayam kampung periode awal reproduksi telah dilakukan di Stasiun Penelitian Fakultas Peternakan Universitas Udayana selama sembilan minggu. Periode awal meliputi periode bertelur pertama, periode mengeram pertama , hingga telur menetas. Materi yang digunakan dalam penelitian ini berupa ayam kampung betina yang berjumlah 15 ekor umur 22 minggu dan enam ekor ayam kampung jantan dewasa kelamin. Tujuan penelitian ini adalah untuk mengetahui berapa tingkat protein ransum yang paling baik untuk ayam kampung betina periode awal reproduksi. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap dengan tiga perlakuan ransum dan lima ulangan.  Ayam kampung ditempatkan secara acak  kedalam tiga perlakuan, yaitu ayam kampung yang mendapat perlakuan A diberi ransum berprotein 11%,  perlakuan B diberi ransum berprotein 13%, dan perlakuan C diberi ransum berprotein 15%. Berdasarkan hasil penelitian didapatkan bahwa selama periode bertelur ayam kampung yang diberi perlakuan ransum dengan tingkat protein yang berbeda tidak menunjukan perbedaan yang nyata (P>0,05) untuk produksi telur, konsumsi ransum, dan konversi ransum. Bobot badan ayam kampung yang diberi ransum dengan protein 15% pada periode bertelur mengalami penurunan paling banyak yaitu sebesar 129,7 g. Selama periode mengeram bobot badan ayam kampung yang diberi ransum dengan protein 11% mengalami penurunan bobot badan yang nyata (P<0,05) lebih banyak dari ayam kampung yang diberi ransum berprotein 13% dan 15% dan memiliki konsumsi ransum tertinggi. Setelah periode mengeram ayam kampung yang diberi perlakuan ransum dengan tingkat protein yang berbeda tidak menunjukan perbedaan yang nyata (P>0,05) untuk produksi telur dan konversi ransum. Ayam kampung yang diberi ransum dengan protein 15% memiliki peningkatan bobot badan tertinggi yaitu 167 g. Dengan demikian pemberian ransum dengan tingkat protein 11%, 13%, dan 15% menunjukan penampilan yang berbeda pada ayam kampung periode awal reproduksi.
