Abstract :
Choosing the method of bacteria identification is crucial to obtain accurate and quick results. This study will analyze the identification results of Gram negative and Gram positive from aerobic bacteria by examination using conventional and automatic methods at Dr. Wahidin Sudirohusodo Hospital Laboratory. A total of 85 samples consisting of 66 Gram negative bacteria and 19 Gram positive bacteria were identified using conventional and automated methods. In this study, there was some correspondent identification result between the conventional as well as the automated methods, namely 31.5% for Gram negative bacteria and 30.8% for Gram positive bacteria. However, the non-correspondent identification result between conventional and automated methods was found greater, namely, 68.5% for Gram negative bacteria and 69.2% for Gram positive bacteria. The non-correspondent identification result was due to the development of bacterial taxonomy and the differences of numbers and types of the biochemical tests between conventional and automatic methods. Bacteria identification using automated method is more accurate and faster than the conventional method, so it is recommended using this particularly for the laboratory and educational referral center. Pemilihan metode identifikasi bakteri sangat penting untuk mendapatkan hasil yang tepat dan cepat. Penelitian ini adalah untuk mengetahui hasil menganalisis identifikasi bakteri aerob Gram negatif dan Gram positif menggunakan metode konvensional dan otomatik di laboratorium RS Dr. Wahidin Sudirohusodo. Sebanyak 85 sampel yang terdiri dari 66 bakteri Gram negatif dan 19 Gram positif diidentifikasi mengunakan metode konvensional dan otomatik. Di telitian ini didapatkan kesesuaian hasil identifikasi antara metode konvensional dan otomatik, yaitu 31,5% untuk bakteri Gram negatif dan 30,8% untuk Gram positif. Namun, ditemukan bahwa ketidaksesuaian hasil identifikasi antara metode konvensional dan otomatik tersebut lebih besar yaitu 68,5% untuk bakteri Gram negatif dan 69,2% untuk Gram positif. Ketidaksesuaian hasil identifikasi ini disebabkan karena perkembangan penggolongan ilmiah (taksonomi) serta jumlah dan jenis uji biokimiawi yang berbeda antara metode konvensional dan otomatik. Identifikasi bakteri dengan metode otomatik lebih tepat dan cepat dibandingkan dengan yang konvensional, sehingga disarankan penggunaan cara tersebut terutama bagi laboratorium di pusat rujukan dan pendidikan
