Judul: Mempelajari tata letak dan sarana dalam mengoptimalkan kegiatan penanganan bahan : studi kasus: factory-3, PT. Yamaha Indonesia
Abstrak: Perancangan tata letak dan penanganan bahan pada dasarnya mempunyai kaitan yang sangat erat. Perancanaan tata letak harus dapat menjamin kelancaran aliran bahan dan penyimpanan bahan, baik bahan baku, bahan setengah jadi maupun produk jadi. Dalam hal ini, sering terjadi perencanaan tata letak dan perencanaan penanganan bahan dilakukan terlebih dahulu dibanding perencanaan fasilitas. Tata letak yang disusun dengan tepat akan sangat membantu dalam proses produksi serta dengan penempatan fasilitas produksi yang baik dapat memperlancar kegiatan penanganan bahan dan perpindahan bahan.

Judul: Desain Tata Letak Ruang dan Fasilitas Produksi Rumah  Pengomposan di PT Tanjungenim Lestari
Abstrak: Industri pulp and paper di Indonesia menghasilkan limbah berupa sludge yang berasal dari Instalasi Pengolahan Air Limbah (IPAL) dan abu sisa pembakaran boiler yang saat ini belum dimanfaatkan secara optimal. Salah satu alternatif penanganan dan pemanfaatan limbah tersebut yaitu dengan proses pengomposan. Proyek ini bertujuan untuk memanfaatkan limbah sludge dan boiler ash dari PT. Tanjungenim Lestari Pulp and Paper untuk dijadikan produk kompos dan menganalisis kualitas mutu kompos yang dihasilkan. Tujuan penelitian ini adalah merancang fasilitas bangunan rumah kompos. Hasil perancangan tata letak dilakukan dengan membuat desain 2D dan 3D dari usulan tata letak yang terpilih menggunakan bantuan software BPLAN90. Tata letak usulan yang terpilih merupakan salah satu dari 12 iterasi Algoritma BLOCPLAN. Layout yang terpilih yaitu layout usulan iterasi 7 dengan total luas area kerja 11236 m2 , total jarak penanganan bahan pada layout iterasi yang terpilih adalah sebesar 1457,72 m, dan nilai efektivitas tata letak sebesar 0,69. Desain 2D dan 3D dibuat dengan bantuan software SketchUp. Kata kunci: BLOCPLAN, IPAL, Kompos, Sludge, Tata Letak, The pulp and paper industry in Indonesia produces waste in the form of sludge originating from the Wastewater Treatment Plant (WWTP) and ash remaining from boiler combustion which has not been utilized optimally. One alternative handling and utilization of this waste is the composting process. This project aims to utilize sludge and boiler ash waste from PT. Tanjungenim Lestari Pulp and Paper to be used as compost products and to analyze the quality of the compost produced. The purpose of this research is to design compost housing facilities. The results of the layout design are carried out by making 2D and 3D designs from the selected layout proposals using the help of BPLAN90 software. The selected proposed layout is one of 12 iterations of the BLOCPLAN Algorithm. The selected layout is the iteration proposed layout 7 with a total working area of 11236 m2, the total material handling distance in the selected iteration layout is 1457.72 m, and the layout effectiveness value is 0.69. 2D and 3D designs are made with the help of SketchUp software.

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.
