Judul: Laju pengeringan spageti jagung pada berbagai kondisi udara pengering dan pengaruhnya terhadap mutu masak
Abstrak: Noodles and pasta drying with conventional method (dry air) has some disadvantages such as long drying time and very much influenced by weather condition. High temperature drying has been widely applied in pasta production. This method gives several advantages such as shorter drying time, increase productivity, and produce pasta with better cooking quality. In this study, corn spaghetti drying conducted at three levels of air velocity (1,29; 0,90; and 0,49 m/s), three levels of temperature setting (temperature level 6, 8, and 10), as well as two levels of drying position (vertical and horizontal towards the airflow). The cooking quality parameters being analyzed were cooking loss, elongation, and texture profile. Corn spaghetti drying using high temperature was significantly reduce drying time compared with conventional drying. Drying rate of corn spaghetti was increased when higher drying temperature used. Corn spaghetti drying rate could be represented well by the Page model thin layer drying equation. Drying position had an effect on corn spaghetti hardness when drying conducted in 1,29 m/s air velocity. While the combination of temperature and drying position had affected elongation of corn spaghetti when air velocity 0,49 m/s was used. The other drying condition were not influenced corn spaghetti cooking quality.

Judul: aKajian perilaku mi jagung selama proses pengeringan menggunakan fluidized bed drier
Abstrak: The objective of this study were to optimize corn noodles drying process utilizing fluidized bed drier, and also to determine the influence of dried noodles moisture content and the amount of water addition in noodles dough to the quality of dried noodles. The study was done in three stages, in which the first stage was done to determine the optimum temperature and air velocity to dry corn noodles. The second stage was done to determine the time needed to dry the corn noodles, and the last stage is used to determine the critical moisture content that has effect over the quality of dried corn noodles. The result of this research concludes that noodles with best rehydration profile can be attained from drying at 60°C and drying air velocity 2.17 m/s. Furthermore, the quality of dried corn noodles was proofed to be affected by its final moisture content and the amount of water added to its dough. Critical moisture content is the lowest amount of moisture content that did not caused cracking on corn noodles. The critical moisture content for noodles which made from dough that has 60% water addition is 12%, while for noodles which made from dough that has 70% water addition it is 11%, and for noodles which has 80% water addition in its dough the critical moisture content is 10% (wb). Dried corn noodles which has optimum quality was made from dough that has 80% water addition and dried at 60°C and drying air velocity 2.17 m/s for 107 minutes until its moisture content reaches 10% (wb).

Abstrak: Balantiosis merupakan suatu penyakit pada manusia dan ababi yang disebabkan oleh Balantidium coli. Penyakit ini pertama kali diamati oleh Kalmsten pada tahun 1857 pada pasien yang mendrita diare, sedang balantidiosis pada babi pertama kali dilaporkan oleh Leukart pada tahun 1862. Parasit ini merupakan protozoa terbesar yang berada pada usus manusia dan babi dan salah satu Giliata yang patogen.
