Abstract

Generator magnet  permanen merupakan salah satu generator populer untuk  sistem energi terbarukan. Generator magnet  permanen dipilih karena efisiensi dan keandalannya yang tinggi. Pada penelitian ini dibuatlah generator magnet permanen 12 kutup dari motor induksi pompa air power jet 125 Watt, dengan cara merubah lilitan stator dan menambahkan Neodymium magnet pada rotor. Setelah lilitan stator dirubah dan magnet telah dipasang pada rotor kemudian dilakukan pengujian dengan memutar rotor menggunakan bor cordlees dan dilakukan pengukuran tegangan pada keluaran generator.  Dari hasil percobaan yang dilakukan dapat dilihat bahwa perhitungan secara teori sangat jauh berbeda dengan praktek. Hal ini disebabkan oleh kurang kuatnya medan magnet yang dihasilkan oleh rotor.

Abstract

The Menaming Dam is located in Menaming Village, about 3 km away from residential areas, so it is far from the reach of electricity service providers. From the dam, the water is distributed through irrigation canals to the rice fields and fishery and contains hydraulic power, then could be utilized for electricity generation. The location of the dam has attractive views so that it becomes tourism, but there is no electricity available, causing its development to be hindered. Utilization of water resources in irrigation can be done by developing a waterwheel as driving for electricity generators. The power plant with an undershot waterwheel is very suitable to be developed because it is easy to manufacture and maintain. Besides that, the structure and shape can add to the beauty and attractiveness of visitors to tourist sites. Now a hydroelectric power plant has been installed with a total power of about 70 W. Electricity is transmitted using cables through the power poles and an LED light is installed on each of them. Furthermore, in one of the stalls in the tourist location, the installation of lights and sockets for charging mobile phones was made. Lights were also installed in an adjacent house.

Abstract

This study aims to determine the influence of convenience, Benefits, and security on consumer preferences in using QRIS as a non-cash payment system. This study uses a quantitative approach with a purposive sampling technique, namely a sampling method based on certain considerations or criteria relevant to the research objectives so that the selected respondents truly match the required characteristics. The number of respondents in this study was 100 people who had met these criteria. Data collection was carried out through an online questionnaire, while data analysis included validity, reliability, normality, multicollinearity tests, T-tests, F-tests, and coefficients of determination processed using SPSS version 2025. The results of the study indicate that ease, Benefits, and security each have a positive and significant effect on consumer preferences in using QRIS. The easier QRIS is to operate, the more consumers are interested in adopting it. Likewise, the greater the perceived benefits, the stronger the tendency for consumers to prefer QRIS as a payment method. In addition, a secure system fosters greater consumer trust, thereby increasing the likelihood of usage. Collectively, these three factors ease, Benefits, and security interact to enhance consumer interest and decision-making in adopting QRIS. The practical implication of these findings is that service providers and policymakers should prioritize the continuous improvement of system usability, perceived benefits, and security features to strengthen consumer trust and encourage wider adoption of QRIS in daily transactions
