The demand for premium beef continues to increase along with changes in the lifestyle of upper middle class, increasing tourists and expatriates from abroad. Local cattle usually cannot produce premium beef, but aging can improve the quality of meat. This study aimed to characterize the physical quality (pH, cooking loss, water holding capacity, and tenderness) of bali beef with different aging times. This study used three types of muscles, which is Longissimus dorsi, Gluteus medius, and Semitendinosus from bali beef aged ± 3 years and body weight of ± 350 kg. Samples were aged at cold temperatures for 1, 21, and 42 days. A completely randomized design with a 3x3x4 factorial was used in this study. Least Square Means test was applied if the data obtained is significantly different. The results showed that the three types of muscle produced relatively the same physical properties, except for cooking loss. The Longissimus dorsi and Semitendinosus muscles were aged for 21 days to show the best results ofmeat tenderness.

The objective of this research was to determine the effect of concentration of seaweed and palm sugar to the quality of nata de seaweed. This research used factorial randomized block design with two treatments and 3 replications. The treatmens were different concentration of seaweed at 1%, 2%, and 3% and different amount of palm sugar at 7.5%, 10%, and 12.5%. The parameters observed were yield, thickness, elasticity, water content and insoluble dietary fiber of the nata. The treatment of seaweed and palm sugar with increased concentrate tended to decrease the water content of nata de seaweed, while the insoluble dietary fiber content of nata de seaweed tended to increase with treatment of seaweed and palm sugar with increased concentrate. The best treatment in this research was the treatment of 10% palm sugar and 3% seaweed (G2R3) resulting nata with insoluble dietary fiber of 1.89%.
