Abstract

Atma Jaya Catholic University of Indonesia has Faculty of Engineering, which is committed to empower its surrounding communities. This empowerment is implemented based on its core values. The present community empowerment activities have been planned through a series of agreements and the main goal of the activities is to develop the entrepreneurship based on the strength of the area. This paper discusses the assistance given by Faculty of Engineering in designing piping installation for supporting aquaponic activities in Desa Sampora. The project was divided into three steps. First, this project focused on observation and data collecting. This first step also involved discussion with experts. Second, it focused on the design process. The result of the first step was used in the design. Third, the design was implemented and installed in the location. All the steps required careful planning to minimize errors. The expected target of these activities was an aquaponic piping design that is feasible to implement to support sustainable and productive entrepreneurship. The final result was piping installation that can grow 120 plants, is easy to clean up, and has area efficiency.

Abstract

Salah satu yang mempengruhi peningkatan efisiensi pompa adalah geometri sudu impeler. Tujuan dari penelitian ini adalah untuk mendapatkan desain geometri impeler terbaik pada mini pompa sentrifugal. Geometri impeler yang digunakan dalam penelitian ini memiliki tiga variasi yaitu: tipe impeller radial miring, radial melengkung, dan radial airfoil. Sudu impeler didesain selanjutnya dibuat mengunakan mesin 3D print dengan bahan filamen PLA. Motor penggerak pompa yang digunakan adalah dinamo 775 DC 12Volt dengan kecepatan putaran pompa diatur menggunakan potensio pada 2000 rpm, 2150 rpm, 2300 rpm, 2450 rpm, 2600 rpm, dan 2700 rpm. Hasil pengujian menunjukkan bahwa perbedaan geometri sudu impeler mempengarui efesiensi mini pompa sentrifugal. Efisiensi tertinggi terjadi pada tipe impeler radial melengkung dengan nilai efesiensi mencapai 19,35% pada putaran 2700 rpm. Kondisi ini lebih baik daripada tipe impeler lainnya dengan trend kenaikan efesiensi meningkat seiring dengan peningkatan putaran pompa.

Abstract

Educational technology in its contribution to the management and learning of education is opening up knowledge horizons about changing strategic environments. We need the growth of science and technology caused by learning and learning activities of innovation. Speaking in this case is inadequate because the concept of technological studies provides a formula for how to bring teaching and learning activities. Then, the application of educational technology, especially ICT (Information and Communication Technology) in education to overcome learning problems has a number of requirements. For example, the need for large investment costs and energy that are skilled in managing and developing education and utilizing technological advancements that will support the process of learning. It is noteworthy that education is a long-term investment. Therefore, investment in basic education facilities must be calculated with future educational outcomes
