Abstrak Perkembangan blog dan telepon seluler terus mengalami peningkatan. Blog mempunyai fungsi yang sangat beragam mulai dari catatan harian sampai dengan media publikasi. Tujuan penelitian ini adalah mengidentifikasikan kebutuhan blog sesuai dengan perkembangannya, melakukan analisa dan perancangan aplikasi mobile blog berbasis Java, menyediakan suatu media blogging baru dengan sistem offline. Metode pengumpulan data dilakukan dengan studi pustaka, penyebaran kuesioner dan wawancara. Hasil pengumpulan data dianalisis dan dipakai sebagai sebagai acuan pembuatan sistem. Metode perancangan yang dipakai dalam pembuatan sistem adalah dengan menggunakan Object Oriented Analysis and Design (OOAD) melalui pendekatan Unified Modelling Language (UML). Hasil dari penelitian ini adalah sebuah aplikasi mobile blog, yang akan memberikan kemudahan dalam pengaksesan blog, kapan saja dan dimana serta memberikan fasilitas blogging secara offline. Kata Kunci

: Weblog, Mobile.
