Abstrak: Kebutuhan dan tingkat konsumsi masyarakat akan penggunaan kertas setiap tahunnya semakin meningkat. Pertumbuhan industri pulp dan kertas dunia pada tahun 2011 mencapai 2,1%, sementara industri pulp dan kertas nasional mencapai 4,1%. Kebutuhan pulp dan kertas dunia pada tahun 2011 mencapai 340 juta ton dan diperkirakan akan naik menjadi 490 juta ton, sedangkan kebutuhan pulp dan kertas dalam negeri adalah 7,8 juta ton (Asosiasi Pulp dan Kertas Indonesia (APKI) dalam Medan Bisnis, 19 Juli 2012). Ketersediaan bahan baku kayu merupakan faktor utama dalam perkembangan industri pulp dan kertas. Penelitian ini bertujuan untuk mengetahui biaya produksi, menentukan efisiensi produksi dengan pendekatan Break Even Point (BEP), menghitung nilai Return on Infestment (ROI) dan menghitung harga pokok dua jenis kertas di PT.

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.
