Judul: Perancangan Tata Kerja Bagian Kupas-Periksa pada Proses Pengolahan Ubi Jalar di PT Galih Estetika Indonesia.
Abstrak: The objective of the research were to examine the workload for several age levels of workers, to observe the tools and equipments utilization effect to fatigue, and also to recommend an optimal work system that related with tools/equipment utilization and work scheduling through ergonomic approach of sweet potato processing. The subjects employed in this research were 12 employees that divided based on age level into young, middle, and old age. The results of this research showed that the highest energy consumption when doing a work is on subject in old age group. Therefore, the morning shift is preferable to be taken by the old age workers with assistance from young and middle age workers, whereas afternoon and night shift were preferable for middle and young age. The highest productivity was coming from the middle age group that was constant in every work shift. The questionnaire results indicated that the workload of subjects on medium workload category, but in case of working equipment, subjects were situated in very uncomfortable category for using working tools and equipment, so the repairments based on anthropometric dimensions are required in order to fit the workers to the task.

Judul: Distribution and Diversity of Ectoparasite Mites on Geckos in Indonesia
Abstrak: Data on the diversity and dispersal of parasitic mites on house geckos in Indonesia are very scarce. In this work, the distribution and diversity of mites living on three species of house geckos, namely Cosymbotus platyurus, Hemidactylus frenatus, and H. garnotii collected throughout Indonesia, has been elaborated. Geckos and mites were captured and immediately preserved in 70% ethanol. Whole mount of the mites was prepared by clearing in lactophenol followed by mounting on polyvinyl lactophenol solutions. The SEM preparation was conducted to examine the detail morphological characters of the mites. The results showed that among 448 individuals of geckos, 221 geckos were infected by Geckobia mites. Prevalences of C. platyurus, H. frenatus, and H. garnotii infested by mites were 14.8%, 50.69%, and 79.6%, respectively. Three different spesies of Geckobia (G1, G2, and G3) could be differentiated; and based on similarities of their morphological characters to ones described in published literatures, Geckobia G2 is Geckobia glebosum and Geckobia G3 is Geckobia bataviensis while G1 could not be identified to the species level. The highest mean intensity of Geckobia G1 infestation was found on H. garnotii (I=7.0), G. glebosum infestation on H. frenatus (I=3.5), and G. bataviensis infestation on H. garnotii (I=11.8). In general, C. platyurus was infested by the least number of mites. Geckobia G1 were found living on the skin folds on the claws, G. glebosum were found mainly on the body and thigh, and G. bataviensis were found on almost all parts of the host’s body. Geckobia mites are distributed randomly throughout Indonesian Archipelago, following the pattern of distribution of their hosts. So it is concluded that Geckobia G1, G. glebosum, and G. bataviensis are sympatric.
