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.

Judul: Inventarisasi dan Identifikasi Tungau Ektoparasit pada Cicak di Kabupaten Cianjur
Abstrak: Ectoparasite mites are parasitic organisms that live on the surface of the host, sucking the blood or feed on hair, fur, skin, or skin secretions. This research aim to inventarisation and identification of mites ectoparasites on gecko in Cianjur areas. The research was conducted from January 2012 until July 2012. Gecko and mites were collected and preserved in 70% alcohol. Whole mount of the mites was prepared used polyvinyl alcohol media. The result showed that there are three species of gecko (Cosymbotus platyurus, Hemidactylus frenatus, and Gehyra mutilata) was infested by Geckobia mites. There are new seven spesies of Geckobia (G4, G5, G6, G7, G10, G11, and G12). Analysis of the presence of mites done by calculate the value of prevalence (P), the average intensity of infestation (I), and the total intensity (It). The prevalence in C. Platyurus gecko (P = 74.38%) is higher than G. mutilata (P = 50%), and H. frenatus (P = 33.33%), while the average infestation intensity (I) and total intensity (It) is the highest found in G. mutilata (I = 10 and It = 11). Geckobia G4 and Geckobia G10 were found only on C. platyurus; Geckobia G5 and Geckobia G12 were found on C. platyurus and G. mutilata; Geckobia G6 were found on whole infected gecko; Geckobia G7 were found on C. platyurus and H. frenatus; and Geckobia G11 were found on H. frenatus and G. mutilata. So it is concluded that the new seven species mites has not a specific distribution pattern of their hosts.

Judul: Peningkatan kualitas produksi air PDAM Tirta Perwitasari, Kabupaten Purworejo : penerapan metode quality function deployment
Abstrak: Air merupakan sumber daya alam yang sangat penting bagi kehidupan. Namun pada saat ini, ketersediaan air telah berkurang hampir mencapai sepertiganya dibandingkan dengan ketersediaan pada tahun 1970 ketika bumi baru dihuni oleh 1,8 milyar penduduk. Peningkatan taraf hidup masyarakat mengakibatkan semakin bertambahnya permintaan akan air bersih, demikian halnya dengan pertumbuhan penduduk dunia. Peningkatan penduduk akan meningkatkan kebutuhan air bersih, sedangkan jumlah air bersih setiap tahunnya semakin menurun. Penurunan kualitas air antara lain disebabkan oleh kurang bertanggungjawabnya masyarakat dalam pengelolaan air. Dengan semakin terbatasnya air, maka masyarakat rela untuk mendapatkan air dengan cara membayar. untuk mencukupi permintaan air bersih, sehingga dipakailah air yang berasal dari PDAM (Perusahaan Daerah Air Minum). Kualitas air minum yang diproduksi oleh PDAM semakin lama semakin rendah. Masyarakat sering mengeluh air yang disalurkan PDAM sering macet. keruh, dan masih bau kaporit. Sehingga banyak masyarakat yang akhirnya hanya menggunakan air PDAM untuk mandi saja, sedangkan untuk minum mereka membeli air minum dalam kemasan yang harganya lebih mahal. Berbagai keluhan lainnya dari masyarakat adalah mulai dari air yang tidak mengalir, pipa bocor. persil bocor, meteran macet, dan sebagainya. Untuk mengurangi berbagai keluhan yang timbul, maka perusahaan harus meningkatkan kualitas pelayanan sesuai dengan yang dikehendaki oleh pelanggan. Agar dapat memenuhi keinginan pelanggan, maka dapat digunakan metode Quality Function Deployment (QFD). Tujuan penelitian ini adalah untuk mengimplementasikan metode QFD untuk meningkatkan kualitas air dan pelayanan PDAM pada masyarakat atau pelanggan.
