<![CDATA[Robot soccer is a combination of sports, robotics technology, and multi agent system, to achieve goals. Besides requiring individual intelligence, it also requires the ability to work together between individuals. The main problem in robot soccer is detecting objects in the form of balls. These problems include varying lighting that produces shadows from the ball, there are objects similar to balls, as well as real-time detection. Ease and lightweight program implementation are also needed in detecting the ball so that it is easy to implement on embedded systems. Computer vision technology helps robot soccer in detecting balls.Therefore, an alternative process is proposed to detect the ball using a combination of color filters and the shape or contour of the object. The results obtained from the experiments showed relatively effective in object detection, with a recall value of 90,69%.]]>

<![CDATA[Resistansi pembumian di Laboratorium Instalasi Listrik Politeknik Negeri Bandung (Polban) sebesar 10,3 Ohm. Nilai tersebut melebihi standar maksimum menurut Persyaratan Umum Instalasi Listrik Tahun 2000 (PUIL 2000) yaitu maksimum 5 Ohm. Proteksi petir di Politeknik Negeri Bandung yang semula menggunakan sistem konvensional beralih ke sistem elektrostatis dikarenakan banyak kawat tembaga yang hilang sehingga banyak elektroda pembumian bekas proteksi petir konvensional yang tidak dipakai. Oleh karena itu elektroda pembumian tersebut bisa dimanfaatkan untuk memperbaiki nilai resistansi pembumian instalasi listrik. Hal tersebut menjadi latar belakang dalam penelitian ini yang bertujuan untuk memperbaiki nilai resistansi pembumian instasi listrik di Laboratorium Instalasi Listrik Polban sehingga bisa mengurangi bahaya sengatan listrik yang mungkin terjadi akibat kegagalan isolasi. Metode penelitian dalam penelitian ini adalah metoda eksperimental yaitu dengan melakukan pengukuran nilai resistansi pembumian instalasi listrik sebelum perbaikan dan setelah perbaikan dengan alat ukur Earth Tester. Perbaikan nilai resistansi pembumian instalasi dilakukan dengan cara menggabungkan elektroda pembumian bekas proteksi petir dengan elektroda pembumian instalasi listrik. Hasil yang dicapai dari penelitian ini adalah bisa memperkecil nilai resistansi pembumian instalasi listrik yang semula 10,3 Ohm sebelum perbaikan menjadi 1 Ohm setelah perbaikan, dan telah sesuai dengan Persyaratan Umum Instalasi Listrik Tahun 2000]]>
