Judul: Kajian Pengurangan Pemborosan Proses Produksi Kemasan Karton Bergelombang dengan Lean Six Sigma di PT Dayacipta Kemasindo Plant Karawang.
Abstrak: PT Dayacipta Kemasindo Plant Karawang merupakan salah satu perusahaan yang memproduksi karton bergelombang. Perusahaan tersebut menghadapi permasalahan pemborosan berupa waktu menunggu, gerakan yang tidak diperlukan, dan produk cacat khususnya produk XYZ. Lean Six Sigma dapat digunakan sebagai pendekatan yang sistematis untuk mengurangi pemborosan tersebut. Penelitian ini bertujuan untuk mengidentifikasi jenis dan penyebab pemborosan pada proses produksi dan menganalisis pengurangan pemborosan dengan Lean Six Sigma di perusahaan tersebut. Metode penelitian menggunakan metode Define, Measure, Analyze, Improve, Control (DMAIC) yang divisualisasikan dengan Value Stream Mapping kemudian ditelusuri akar masalahnya menggunakan Root Cause Analysis berupa diagram fishbone. Hasil usulan perbaikan menunjukkan pengurangan aktivitas Necessary but Non Value Added (NNVA) dari 24.22 menjadi 6.22 jam, aktivitas Non Value Added (NVA) dari 21.73 jam menjadi 6.00 jam. Pengurangan masing-masing aktivitas dapat meningkatkan nilai Process Cycle Efficiency (PCE) dari 4.27% menjadi 9.48%, dan peningkatan nilai sigma dari 3.95 menjadi 4.20.

Judul: Analisis Pengurangan Jumlah Produk Cacat pada Industri Kertas dengan Pendekatan Lean Six Sigma
Abstrak: The high number of the defective product that occur in each company can affect quality. PT. X is a company engaged in the pulp and paper product. Lean approach does not allow for waste, in this case, defective product. Product defects that often arise in this industry are paper holes, dirty paper, folded, size variations and foreign contamination. The purpose of this study is to identify the causal factors in the production line of a product defect based on six sigma stages. The solution that can reduce the number of defects. The stages of six sigma are define, measure, analyze, improvement and control. The results of calculation of the value sigma of paper holes for two months was 4.66 and 4.58. Dirty paper has a sigma value of 4.99 and 5.06. The sigma level indicates that the performance of the production is above average Indonesian company. The costumer complaint coming into the company for folded paper, size variations and foreign contamination has decreased from 2010 to 2011. But it has not reached the six sigma target. Therefore, the company needs to be improved using the Lean tool, that is Kaizen Blitz.

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.
