Judul: Analisis Lean Manufacturing pada Produk Teh Celup dengan Metode Value Stream Mapping
Abstrak: Produktivitas pada lini produksi dapat ditingkatkan dengan mengeliminasi segala pemborosan yang ada pada lantai produksi. Penelitian ini bertujuan untuk mengidentifikasi dan merancang perbaikan berkelanjutan untuk produk Sarimurni Teabag 25 yang diproduksi di PT Y. Value stream mapping merupakan sebuah tool pada lean manufacturing yang mengidentifikasi pemborosan berikut penyebab permasalahan melalui current dan future state map. Mengacu pada Toyota production system (TPS), teridentifikasi bahwa terdapat beberapa pemborosan yang terjadi di lini produksi seperti transportasi, inventori, gerakan, waktu menunggu, produksi berlebih dan produk cacat. Total lead time efektif adalah 1 325 detik dari total lead time keseluruhan 4 408 detik. Analisis produktivitas menunjukkan besarnya persentase aktivitas tidak bernilai tambah akibat kerusakan mesin pada proses akhir yang sering terjadi. Upaya dari perbaikan produktivitas diilustrasikan pada peta kondisi masa depan dengan penerapan beberapa lean tools: one-piece flow, 5S, poka yoke, dan andon. Pendekatan lean pada lini produksi dapat mengurangi 53% lead time per satu kardus produk menjadi 2 069 detik.

Judul: Process and Lean Manufacturing Analysis of Ready to Eat Curry Sauce Product with Value Stream Mapping Method in PT XYZ
Abstrak: Produktivitas dapat ditingkatkan dengan mengeliminiasi atau meminimalisir pemborosan yang terjadi pada lini produksi. Penelitian ini bertujuan untuk mengidentifikasi aliran dan tahapan proses, mengevaluasi kendala serta pemborosan yang terjadi serta merancang perbaikan pada produksi saus gulai. Value stream mapping adalah tools pada konsep lean manufacturing yang berguna untuk mengetahui aliran informasi dan material serta mengidentifikasi pemborosan yang terjadi pada lini produksi melalui pemetaan. Berdasarkan konsep Toyota Production System (TPS), memborosan teridentifikasi pada lini produksi adalah pergerakan, waktu menunggu dan proses produksi berlebih. Total lead time pada pemetaan sekarang adalah 25621,4 detik. Analisis pada pengembangan peta masa depan menunjukkan penggunaan sumberdaya yang masih kurang optimal sehingga menyebabkan berbagai pemborosan pada lini produksi. Usulan perbaikan pada peta masa depan seperti penerapan 5S, standarisasi tugas serta jumlah pekerja, sistem andon dan proses FiFo. Usulan perbaikan dapat mengurangi lead time menjadi 25018,2 detik., Productivity is described through good use of resources. Productivity can be increased by eliminating or minimizing wastes that occur on the production line. This research is aimed to identify the flow of information and stages of the process, evaluate wastes that occur and design improvement to the production of curry sauce. Value stream mapping is a tool in the lean manufacturing concept that is usefull for knowing the flow of information and materials as well as identifying wastes that occur in the production line through mapping. According to Toyota Production System (TPS) concept, this research has identified several wastes, motion, waiting and extra-processing. Total lead time on the current mapping was 25621,4 seconds. Analysis on the future map showed that used of resources was still less than optimal. The future map suggested implementation of 5s, standardization of tasks and number of workers, andon system and FiFo process.The suggested improvement was able to reduce the lead time to 25018,2 seconds.

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.
