Judul: Perbaikan Aliran Proses Produksi dari Aspek Tata Cara Kerja dan Tata Letak Pabrik dengan Metode Value Stream Mapping (Studi Kasus PT. X)
Abstrak: Effectivity and efficiency of production flow can be achieved by eliminating identified waste in the flow process. Value stream mapping is a fundamental tool in lean manufacturing system to identify and eliminate waste. The objective of this research is to analyze the production flow in PT. X from the work procedure and factory layout aspect, so that the effectivity and efficiency of the flow process can be improved continuously. This research consists of several important steps; choosing a product to be observed, making the current state VSM for the chosen product, analyzing the current state VSM, and then making the future state VSM. The depiction of current state VSM shows that the production lead time for the observed product is 17 hours 53 minutes and 52 seconds, with the percentage of value added time counted 56,87%. The result of improvement analysis in this research shows a reduction of production lead time for 13,16%, and also an improvement of value added time percentage to 60,26%.

Judul: Analisis Perbaikan Kinerja Aliran Material Can BodyProduk X dengan Metode Value Stream Mapping pada PT XYZ.
Abstrak: Efisiensi dari aliran material can body dapat dicapai dengan mengeliminasi pemborosan yang teridentifikasi. Penelitian ini bertujuan untuk mengidentifikasi pemborosan dan mengeliminasinya dengan merancang alternatif perbaikan, khususnya untuk material can bodyproduk X yang diproduksi di lini 3 PT XYZ. Value Stream Mapping (VSM) merupakan salah satu metode dalam sistem lean manufacturing yang dapat digunakan untuk mengidentifikasi dan mengeliminasi pemborosan secara tepat. Penelitian ini dilakukan dalam beberapa tahap, yakni identifikasi terhadap famili produk dan aliran produk untuk diamati, memetakan current state, mengidentifikasi pemborosan dan solusi perbaikan, serta pemetaan future state. Berdasarkan analisis dari current state VSM, teridentifikasi adanya pemborosan pada inventori, transportasi, gerakan, dan tenaga kerja. Waktu value added sebesar 313,34 detik dari lead time sebesar 26.459,74 detik. Hasil analisis menunjukkan bahwa terdapat aktivitas non value added yang besar dalam aliran materialcan body yang diakibatkan oleh adanya stage area. Penerapan sistem kanban diusulkan sebagai alternatif perbaikan. Perbaikan kemudian diilustrasikan pada peta kondisi masa depan. Hasil dari future state VSM menunjukkan bahwa terdapat pengurangan aktivitas non value added yang signifikan sehingga menghasilkan lead time sebesar 437,04 detik. Hasil dari penelitian ini meningkatkan efisiensi aliran material can body hingga 70,8%.

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.
