The objective of this study was to determine the effect of piperine as a phytogenic feed additive on quail performances and egg quality. The experiment used a completely randomized design with five treatments and four replications and used ten quails with one week of age in each replication. The piperine was added to the diets at concentrations of 0 (T0), 15 (T1), 30 (T2), 45 (T3), and 60 mg/ kg body weight (T4) for 8 consecutive weeks. The results showed that addition of 60 mg/kg body weight (T4) of piperine significantly (P<0.05) reduced feed consumption, egg production, egg mass, income over feed cost (IOFC), and increased water consumption as compared to the other treatments. The addition of 15-60 mg piperine/kg body weight significantly (P<0.05) reduced eggshell weight and increased egg yolk color score. The conclusion of this experiment was that the addition of piperine at 15-45 mg/kg body weight could be used as phytogenic feed additive to improve performance, IOFC, haugh unit, and yolk color.

Carcass composition was determined in 44 grey kangaroos, 17 red kangaroos and 34 sheep.

Whey is a liquid produced from the separation of curd that its utilization is still very limited, so it can cause environmental pollution. The purpose of this study was to determine the effect of starter concentration on alcohol, pH, and total titrated acids in whey kefir. Pasteurized whey was added starter with concentration of 5, 7, and 9% (w/v) then incubated at 20°C for 24 hours. The research method used was Completely Randomized Design (CRD) with 3 treatments and 3 replications. The treatment used was cow milk added 5% starter as control (T0), whey added starter 5% (T1), whey added starter 7% (T2), and whey added starter 9% (T3). The data were analyzed using Analysis of Variance (ANOVA) and continued by Duncan Multiple Range Test (DMRT). The results showed that the higher starter concentration, the higher the alcohol content and tend to increase the total value of titrated acids (TTA).

Penelitian ini bertujuan untuk mengetahui pengaruh lama penyimpanan dengan berbagai bahan penstabil terhadap sifat fisikokimia mayonnaise. Jenis bahan penstabil yang digunakan pada penelitian ini yaitu CMC, gum arab, dan xanthan gum dengan penyimpanan menggunakan suhu ruang selama 8 hari. Penelitian ini menggunakan 4 sampel 5 perlakuan dan 3 kelompok. Penelitian ini menggunakan sampel berupa S0 (tanpa bahan penstabil), S1 (CMC 1%), S2 (Gum arab 1%), dan S3 (Xanthan gum 1%).  Hasil penelitian menunjukkan bahwa penambahan berbagai bahan penstabil dan lama penyimpanan mayonnaise pada sifat fisik menunjukkan hasil nyata (P<0,05) pada penyimpanan dan tidak terjadi interaksi namun pada sifat kimia menunjukkan hasil (pH, FFA, Kadar air) nyata (P<0,05) pada berbagai jenis bahan penstabil dan penyimpanan serta ada interaksi pada parameter kadar air. Berdasarkan penelitian ini dapat disimpulkan bahwa masing-masing bahan penstabil memiliki keunggulan dan kestabilan yang berbeda disetiap parameter sehingga perlakuan terbaik tidak bisa dipastikan.
