Judul: Studies on Hydrocolloids and CaCl2 Effect on Gelatinization Profile of Raw Material and Its Application on Breadfruit Bihon-Type Noodle.
Abstrak: The objectives of this research were: (1) to study the effect of rice flour addition on gelatinization characteristics of raw material, (2) to study the effect of hydrocolloids and salt addition on pasting profile of raw material and (3) to investigate the effects of flours, hydrocolloids and salt interactions on the quality of bihon-type noodle making. The pasting properties of breadfruit flour alone and its composite with 15 and 30% rice flour were investigated. The viscosity of the flour mixtures increased with increasing proportion of rice flour, except for peak viscosity. The addition of 15% rice flour resulting in better characteristics of mix flour compared to the addition of 30% rice flour, showed by higher setback and lower breakdown viscosity. The pasting properties of mix flours consists of breadfruit flour alone or composite of 85% breadfruit flour and 15% rice flour, hydrocolloids, including guar gum and konjac flour, in the presence or absence of CaCl2 were investigated using Rapid Visco Analyzer. The addition of 1% CaCl2 lowered the viscosity of mixed flours, while addition of 2% CaCl2 increased the viscosity of mixed flours. The addition of CaCl2 improved the heat stability of breadfruit flour in the presence of both guar gum and konjac flour, showed by the decreased value of breakdown viscosity. Bihon-type noodle made from composite mix flours as described above were prepared. Bihon-type noodle quality of composite mix flour in the presence or absence of CaCl2 was examined by cooking loss, rehydration weight, color, texture analysis and sensory tests. It was found that the substitution of breadfruit flour with 15% rice flour in the presence of guar gum improved the characteristics of bihon-type noodle quality, i.e. lower rehydration weight and higher hardness. In the presence of konjac flour, addition of rice flour resulting in higher cooking loss and lower elasticity.

Judul: Development of organic rice noodle and Pad Thai preparation
Abstrak: This study was aimed to develop rice noodle from broken organic Jasmin rice with addition of different additives. Physicocemical of flours were determined as dried rice noodle was prepared with wet casting method and determined in chemical, physical and cooking properties. The physicochemical properties of organic rice flour (ORF) in comparison with commercial rice flour (CRF) and tapioca flour (TPF) were significantly different (p<0.05). The ORF contained low amylose content compared with others (p<0.05). Swelling power of ORF (10.76) at higher temperature (85°C) was lower compared to others (12.37 for CRF and 21.33 for TRF). Water absorption index of ORF was significantly higher at ambient temperature but lower than CRF and TPF in higher temperature (p<0.05). There was no significant difference in term of water solubility index between ORF and CRF both at ambient and high temperature (p>0.05). Addition of 1% (w/w) microbial transglutaminase (MTGase) increased yellowness of cooked rice noodle from -1.34 to 8.23 as well as improved tensile strength and cooking weight when compared to control (p<0.05). Addition of glycerol mono-stearate (GMS) 1% (w/w) significantly increased hardness (787.03g to 1331.00g) of cooked rice noodle as well as increased cooking loss (7.43% to 10.86%) (p<0.05). Addition of 2% (w/w) NaCl improved the noodle quality significantly in tensile strength (42.91g to 59.24g) and cooking loss (7.43% to 4.78%) (p<0.05). Rice noodle with 2% (w/w) NaCl addition was chosen and compared to the commercial rice noodle in the form of Pad Thai dish. The commercial rice noodle was significantly superior to the developed rice noodle on textural properties and sensory ratings in terms of overall acceptability, firmness, elasticity and stickiness (p<0.05). Further study should be finding or modifying process parameters of organic rice noodle such as combining flours or other additives addition to improve noodle quality that comparable to commercial rice noodle, especially the textural properties

Judul: Ornithonyssus Bursa (Berlese, 1888) Famili Macronyssidae yang Menyerang Unggas Dan Penaggulangannnya
Abstrak: Ornithonyssus bursa adalah tungau penghisap darah pada unggas di daerah tropis dan subtropis. Tungau ini relatif kecil, dengan panjang tubuh antara 700-1000 mikron dan lebarnya 250-490 mikron. Tubuhnya bulat berwarna coklat kekuningan sebelum menghisap darh dan berwarna merah setelah menghisap darah dari induk semangnya.
