Abstract This study aims to develop an android-based application to calculate the amount of fuel adjusted to the distance and speed of the ship based on the trajectory (way point). The calculation of distance in this application uses the concept of a spherical triangle which is used in voyage navigation. This development adopts the Waterfall model with the stages of Requirement Engineering, Design and implementation, Testing, Release and Maintenance. At the product review stage, it involves software experts (to provide criticism and suggestions for improvement), then testing is carried out by comparing the results of calculations using applications with manual calculations and ECDIS (electronic Chart Display Information System). The test results show that there is no significant difference between the results of calculations using the application with manual calculations and ECDIS. Thus, this application can be used to calculate the amount of fuel needed according to the distance traveled and the speed of the ship based on the selected trajectory.

Background: Chronic suppurative otitis media (CSOM) is one infectious disease of the middle ear, most commonly caused by Pseudomonas aeruginosa. A high number of patients come to the ENT outpatient clinic with active benign type of CSOM. The bacteria Pseudomonas aeruginosa is capable of producing biofilm which protects itself from penetration of antibiotics, and therefore creates resistance towards antibiotics and difficult to eradicate. Objective: The aim of this study was to compare the sensitivity levels of chloramphenicol, polymyxin-neomycin, cyprofloxacin and ofloxacine against Pseudomonas aeruginosa in patients with active benign type CSOM in ENT clinic. Method: The method used was across sectional study on 25 patients, from August 2010 until December 2010. Samples were taken withear swab and then put on sensitivity test to chloramphenicol, polymyxin-neomycin, cyprofloxacin andofloxacine using the diffusion disc method. The analysis used in this study was Cochran test. Results: Results showed a significant difference in sensitivity among chloramphenicol (38,70%), polymyxinneomycin(83,87%),cyprofloxacin(90,32%)andofloxacin(58,06%)withp=0,000(p<0,05).PostHocanalysisusing the Mc Nemar indicated that there were significant differences in sensitivity betweenpolymyxin-neomycin to chloramphenicol with p=0,000 (p<0,05), ciprofloxacin to chloramphenicol andciprofloxacin to ofloxacine with p= 0,002, but there were no significant differences between cyprofloxacinto polymyxin-neomycin with p=0,687, polymyxin-neomycin to ofloxacin p=0.057 and ofloxacin tochloramphenicol p=0,109.   There were significant differences in antibiotic ear dropssensitivity to Pseudomonas aeruginosa in patients with active benign type of CSOM. Cyprofloxacin andpolymyxin-neomycin were more sensitive than ofloxacin and chloramphenicol. Keywords: Pseudomonas aeruginosa, active benign type of chronic suppurative otitis media, antibioticear drops.  Abstrak :  Latar belakang: Otitis media supuratif kronik (OMSK) merupakan penyakit infeksi kronik telinga tengah yang sering dijumpai di klinik THT. Penyebab tersering OMSK adalah bakteri Pseudomonasaeruginosa. Pseudomonas aeruginosa mempunyai kemampuan untuk membentuk biofilm yangmelindunginya dari penetrasi antibiotik sehingga menimbulkan resistensi terhadap antibiotik dan sulituntuk eradikasinya. Tujuan: Untuk mengetahui perbandingan tingkat sensitivitas kloramfenikol,polimiksin-neomisin, ciprofloksasin dan ofloksasin terhadap isolat Pseudomonas aeruginosa padapasien OMSK benigna aktif di klinik THT RSMS. Metode: Metode yang digunakan adalah crosssectional terhadap 29 pasien OMSK di klinik THT RSMS periode bulan Agustus 2010 - Desember2010.
