Judul: Analisis dan Perbaikan Sistem Kerja Berdasarkan Metode Studi Gerak dan Waktu Pada Lini Produksi Squash Orange di PT. Buanasari
Abstrak: Assessment of work productivity should be done routinely by a company. Achieving high productivity required special attention to efficiency and effectiveness of work. For that reason, there was a need to analyze working movement and work time required for one cycle of process. Time required at the beginning and the end of a process shift was different depends on the decrease of labor’s motivation and stamina, which related to fatique condition of labor. Fatique could be caused by working conditions and work capacity of workers. Motions were analyzed and grouped according to the cycle and type of motion. Average time of each motion adjusted with Westinghouse rating and allowances to obtain the standard time. Standard time for the squash orange production from was 25.46 seconds/bottle, while the standard time for the packaging process was 20.22 seconds/bottle. Productivity can be calculated by dividing the daily product output with the number of workers and duration to finish one cycle of process. It was obtained from the calculation that each production worker’s productivity was 36 bottles/hour, while the packaging worker’s productivity was 7 cartons/hour.

Judul: Peningkatan Produktivitas melalui Modifikasi Peralatan dan Metode Produksi di PT. Buana Segar Lestari, Tangerang Selatan.
Abstrak: Manufacturing plant affects many aspects of food production. One of those important aspects it affects is productivity. Low productivity often results in low yield, huge loss, and undoubtedly reduced revenue. Due to the importance of those impacts, any problems affecting productivity should be addressed immediately with appropriate measures. In PT. Buana Segar Lestari, these productivity problems include inefficient processing technology, bottleneck processes, and non-value-adding production process. In order to handle those problems, modification of manufacturing equipments and methods are necessary. The modifications are focused on improving filling efficiency by modification of filling equipment and reducing process cycle time by eliminating bottleneck processes. This internship assess the productivity of PT. Buana Segar Lestari before and after modifications in four aspects: production efficiency, length of process steps, material flow analysis, and line capacity efficiency. After modification, production efficiency increase by 8.54 percent, while 2 bottleneck processes are successfully eliminated. Amount of products waiting in bottleneck process is also reduced from 3372 bottles to only 1508 bottles, while the maximum capacity for 8 hours production increase from 4032 bottles to 7694 bottles. Through those improvement, the line capacity efficiency also increase from 42,70% to 64,60%. Thus, the modifications to manufacturing equipment and methods are proven to be able to increase productivity in PT. Buana Segar Lestari, South Tangerang.

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.
