Abstrak: One of ectoparasites on Hemidactylus lizard are Geckobia mites of family Pterygosomatidae. This research aimed to determine the diversity, prevalence, infestation intensity, chaetotaxy, and total intensity of ectoparasites mites on Hemidactylus lizard in Depok. Mites were taken from head, eyes, a part of body, thigh, tail, front finger, and back finger, then preserved in 70% alcohol. Mites were prepared on whole mount method using polyvinyl alcohol (PVA). This research found 107 of lizard and nine species of ectoparasites mites namely Geckobia sp1, G2 (Geckobia glebosum), Geckobia sp4, Geckobia sp5, Geckobia sp7, Geckobia sp10, Geckobia sp11, Geckobia sp13, and Geckobia sp14. Prevalence mite on lizard H. garnotii was 85.18%, and H. frenatus was 84.61%. The highest of mite infection intensity on lizard H. garnotii was mite G1, and H. frenatus was mite G. glebosum. The highest infection intensity of mite was on H. garnotii. Leg chaetotaxy observations indicated that mites G2 is G. glebosum, G5 and G11 including Geckobia indica group, G10 and G14 including G. gleadoviana group, G13 including G. keegani group, and G4 including Geckobia group 1.

Abstrak: Ectoparasite mites are parasite that live on the body surface of the host. This research aims to see the diversity, intensity of infestation, and prevalence value of mites on house gecko, Cosymbotus platyurus, in Depok Area. Geckos were collected in three locations, such as houses, markets, and the city forest, and then preserved in 70% ethanol. Mites were collected from the head, tympani, armpit, part of body, thigh, tail, fingers, and toes of the geckos. From 140 individuals collected, 246 individuals of mites were found. The mites could be grouped in the genus of Geckobia and the family of Pterygosomatidae. Based on the morphological characteristics, the mites could be grouped into G1, G4, G5, G6, G7, and G10. Species identification of the mites based on chaetotaxy had confirmed that G5 and G10 were of close similarity to G. gleadoviana, while G4 and G6 were Geckobia Group 1, whereas the similarity of chaetotaxy G1 and G7 could not be confirmed. Prevalence of ectoparasites mites was the highest (55%) on the geckos from the city forest. The highest infestation value (4.0) were found in house geckos infected by G6, while the highest total infestation (4.6) was found among the geckos collected from the city forest.

Abstrak: Sorghum can be used as a basic ingredient in developing ready to eat cereals. The general aim of this study was to develop cereal milks based beverages with sorghum as a main ingredient. The materials used to make cereal milk sorghum were milk powder, sorghum flour, sugar, cocoa powder, vanillin powder, and salt. This study covered two stages of experiment, i.e. preliminary and main experiments. The objective of preliminary study was to produce sorghum flour that can be rehydrated and has good characteristics. Flour that can be rehydrated known as pragelatinized flour. Pragelatinized sorghum flour can be achieved by studying the comparison of the amount of water added in the cooking stage that studied in the preliminary experiment. The ratio of coarse sorghum flour and water (w/v) tested were 1 : 2.5, 1 : 3, 1 : 3.5, 1 : 4, 1 : 4.5. The physical properties of the products resulted such as yield, water solubility index, and the rehydration time were analyzed. Based on these test results, the ratio of flour and water to be used in the main study was 1 : 4. The main study aimed to get a cereal milk formula that was suitable and acceptable by consumers. Variables observed on the main research in determining the optimum formulation of cereal milk were the amount of pragelatinized sorghum flour and milk powder added. The organoleptic test conducted showed that the formulation with a ratio of milk and pragelatinized sorghum flour 3 : 7 was chosen. Based on proximate analysis, the chosen formula contain (dry basis) 5.82% moisture content, 5.87% fat, 8.16% protein, 2.73% ash, and 83.24% carbohydrate. Chosen formula also contain 14.76% dietary fibre and total phenolic compound 3.28 mg GAE (Gallic Acid Equivalent)/ g product. Financial analysis that has been done shows milk cereal product development is feasible.
