Abstract

Renewable energy sources are worthy of being utilized and developed in Indonesia. Renewable energy has great potential considering Indonesia's geographic location. By utilizing solar panels, solar energy can be converted into electrical energy. Solar energy into electrical energy is still not optimally utilized. One of the methods used to optimize the use of solar energy into electrical energy through solar panels is a solar tracker system and real-time remote monitoring based on the Internet of Things. With a solar tracker system and remote monitoring, the solar energy absorbed by the solar panels which is then converted into electrical energy will be greater. The design of this solar tracker and remote monitoring system, to be able to work optimally and be able to find out how optimal the use of the solar tracker is regarding the amount of power produced by the solar panels and being able to monitor environmental conditions including temperature, humidity, light intensity, air conditions and being able to find out how much influence these parameters have on the amount of power produced. The results of the research that has been carried out can be concluded that the power produced by solar panels with a solar tracker is an average of 21.61W. Light intensity is a parameter that influences the three other parameters on the amount of power produced by solar panels. The use of a solar tracker on a solar panel significantly impacts the amount of power produced by the solar panel.

Abstract

Radio broadcasting is a source of information for the public. In delivering information, the broadcaster must read the text of the news before it is transmitted through a radio transmitter. Implementing a text-to-speech conversion can help solve this problem. The purpose of this study is to develop a Broadcasting Service Application by implementing text to speech on a Web-Based Radio Broadcasting service application that can convert data/information in text form into information in the form of voice. This paper does not discuss text-to-speech conversion techniques but emphasizes how to apply text-to-speech conversion techniques in web-based broadcasting service applications, especially news and music data management. This application utilizes web hosting services and Google voice services to convert text data into voice. The method used is Analyzing the application system of Broadcasting Radio services, Application of Text to speech (TTS), which functions to convert text into sound before being transmitted to broadcasting stations and to test the response of the conversion results and data management to the quality of the design. The process carried out in this system, namely retrieval of text data from the news database, converting text data into sound, adjusting the volume of music and sound information, and updating the status of the text data that has been broadcast. Based on application testing carried out with the Black Box Testing Method, all functional applications have been running well and are now successfully operationalized.

Abstract

Saat ini kWh meter konvensional masih digunakan untuk memantau konsumsi listrik di Indonesia, sehingga masih diperlukan petugas yang mengunjungi rumah pelanggan setiap bulannya. Hal ini mengakibatkan Perusahaan Listrik Negara (PLN) harus menyediakan pencatat meter yang menjadi beban biaya perusahaan. Sementara itu pencatat meter mengalami kendala ketika rumah pelanggan kosong dan tidak dapat dicatat meternya. Permasalahan ini dapat diselesaikan jika menggunakan teknologi pencatatan yang otomatis dan bisa dikendalikan dari jarak jauh. Saat ini kemajuan teknologi memungkinkan konvergensi antara saluran komunikasi dengan berbagai hal. Teknologi yang dikenal dengan Internet of Things (IoT). Penelitian ini bertujuan untuk membuat pemantauan konsumsi energi listrik berbasis Internet of Things (IoT). Alat ini akan membantu perusahaan (PLN) dalam memantau penggunaan listrik setiap pelanggan tanpa petugas pencatat meter. Prototype alat ini telah berhasil dikerjakan menggunakan PZEM-004T yang kemudian mampu menampilkan tegangan, arus daya, power factor dan waktu. Luaran dari alat kwH meter teknologi IoT ini kemudian dikirimkan ke basis data Firebase. Firebase memiliki keunggulan karena ditempatkan dalam cloud. Sehingga data yang diperoleh dapat juga ditampilkan dalam aplikasi android. Hasil pengujian dari prototype kemudian dilakukan pengujian beban dan dibandingkan dengan alat ukur sejenis yang ada di pasaran. Pengujian beban menghasilkan keakuratan sistem dengan rata-rata persentase akurasi tegangan: 99.25%, arus: 99.82%, daya: 97.50% dan factor daya: 98.78%. Penelitian ini menghasilkan prototipe menggunakan ESP32 dan PZEM-004T yang sangat akurat sehingga dapat direkomendasikan untuk pencatatan daya listrik yang mampu mengurangi beban biaya operasional PLN.
