Gelatin adalah suatu protein yang didapatkan dari hasil hidrolisis kolagen pada tulang dan kulit hewan. Ceker itik mengandung kolagen, jumlahnya banyak dan belum dimafaatkan dengan baik sehingga dapat dijadikan sebagai alternatif bahan baku gelatin. Gelatin dikelompokan menjadi gelatin tipe A dan B. NaOH dapat digunakan pada proses demineralisasi pembuatan gelatin tipe B. Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi dan pola hubungan NaOH terhadap rendemen, kadar air dan kadar abu gelatin ceker itik. Penelitian dilakukan secara eksperimen menggunakan Rancangan Acak Lengkap (RAL), dengan 3 perlakuan konsentrasi NaOH (P1 = 3%; P2 = 5% dan P3 = 7%). Hasil penelitian diuji menggunakan analisis ragam, dilanjutkan dengan uji jarak berganda Duncan dan uji polinomial orthogonal. Hasil penelitian menunjukkan bahwa konsentrasi NaOH berpengaruh nyata terhadap rendemen, kadar air dan kadar abu gelatin ceker itik. Konsentrasi NaOH terbaik pada kosentrasi 3% dengan nilai rendemen 4,77%, kadar air 7,20% dan kadar abu 3,48%.

The purpose of this research was to find out physical properties of yogurt during storage at 4ÂºC. Yoghurt starters were using Lactobacillus bulgaricus FNCC 0041 and Streptococcus thermophilus FNCC 0040 (1:1). Yoghurt starter was inoculated on 10% (w/v) of skim milk and 10% (w/v) of skim milk which contained 5% (w/v) of sucrose, incubated at 42ÂºC for 6 hours then storage at 4ÂºC for 30 days. The result showed that posacidification until 6 days storage, pH tend constant between 6 days and 30 days. Until 9 days texture tend constant, but after 9 days storage texture tend decreasing. Storage yogurt at 10ËšC for 12 hours before 4ËšC gave higher viscosity, viscosity tend constant until 30 days storage. Water Holding Capacity increasing until 6 days storage, after 6 days tend constant. Sineresis increasing until 6 days storage, after 6 days tend constant. It concluded that physical properties of yogurt gave a little changes on first week storage, after that tend constant until 30 days storage. Â Keywords: yogurt, pH, Texture, Viscosity, Water Holding Capacity, Sineresis

The purposes of this research were to investigate the difference of harvesting time on honey production, viscosity, moisture and sugar content, as well as identifying the best harvesting time.The material used in this research was honey from Calliandra plantation. The method used was experimental design using Completely Randomized Design (CRD) with 3 treatments and 5 replications. The treatment consisted of harvesting time on day 11 P1on day 14 P2, and on day 17 P3. Data obtained were analyzed by ANOVA and continued by LSD test. The results showed that the treatments had significantly effect (P<0.01) on honey production, viscosity, water and sugar content. On P1, production obtained was 1.59 L/colony/harvest, while 0.72 and 0,26 from P2 and P3, respectively. Moisture of P1, P2, P3 respectively were 22.02, 21.00, 19.48 %, respectively. Viscosity obtained was 11.43, 18.56, and 33.67 P. Sugar content were 69.46%, 70.59%, and 71.67%, respectively. In conclusion, viscosity and sugar content of honey will increase when it is harvested on day 17, but decrease when it is harvested on day 11. However, harvesting time on day 11 is the best choice for farmer due to highest production obtained, but inadequate of standard of water content, viscosity, and sugar content.

The purpose of this research were to find out effect of using citric acid and lactic acid combination in liquid and encapsulated forms on broiler carcass percentage and internal organ weights (liver, pancreas, lymph, bile). The material used for this research was 108 Cobb broiler chicks with average initial body weight of 44,00 Â± 3,37 g. The method used in this field experiment was Completly Randomized Design with 2 factors and 4 levels, and if there were significant influence it would be tested with Duncanâ€™s Multiple Range Test. The result showed that citric acid and lactic acid combination in either liquid or encapsulated form showed no significant effect (P>0,05) on carcass percentage and liver, pancreas and lymph weights of broiler but it significantly affect (P<0,01) bile weight. The addition of 0.4 % citric acid and lactic acid combination in either liquid or encapsulated form gave the best result on percentage carcass. The conclusion that the additions of different level of citric acid and lactic acid combination in encapsulated form on broiler feed only gave significant effect on lymph weight. Â Keywords: citric acid and lactic acid combination, liquid, encapsulated, carcass percentage, internal organ

This study was conducted to evaluate the external physical quality and sensory quality of eggs fed diets added with purslane meal (Portulaca oleraceae) as a source of alpha-linolenic acids. The materials used were Hy-Line Brown laying hen (n= 150 hens, 54 weeks old). The design of the study was a one way classification with five experimental diets. Each diet was replicated five times with five hens for each replication. The diets were formulated by supplementing purslane meal to a basal diet. The levels of purslane meal were 0% (T0), 2% (T1), 4% (T2), 6% (T3), 8% (T4). The diets were given to the hens for 35 days with 7 days of adaptation period. To analyse the external quality of the eggs, a total of 30 eggs (n=6 per dietary treatment) collected at day 33, 34, and 35 were used. The sensory analysis used eggs from day 32. The results of the external quality of eggs showed that the addition of purslane meal (Portulaca oleracea) into the diets of laying hens reaching a level of 8% tended to increase egg weight and did not decrease shell thickness, shell weight, the shape index, and specific gravity (P>0.05). Dietary inclusion of purslane meal up to a level of 8% significantly increased (P<0.01) the preference of egg yolk color while texture, taste, flavor, and overall acceptance were not affected. The conclusion is that purslane meal can be included in the laying hen diets up to a level of 8% without decreasing the external physical quality and the sensory quality of boiled eggs. Diets containing purslane meal increase the preference of egg yolk color due to the increase in yolk color intensity.
