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.

Abstract

The reliability of electric power distribution, in mitigating fault and disturbances, is strongly influenced by the effectiveness of grounding systems. A key factor in achieving low grounding resistance an essential requirement per construction and safety standards is soil condition. High grounding resistance is frequently observed in field implementations and is closely linked to soil resistivity, type, stratification, moisture content, and acidity (pH). This quantitative applied research addresses the persistent challenge of high grounding resistance by experimenting with investigating six grounding system models subjected to varying soil acidity levels. The study introduces the use of eco enzyme as a natural additive to modify soil pH and examines its effect on grounding resistance. Findings reveal that eco enzyme application successfully lowers soil pH, with an optimal reduction in grounding resistance observed at pH 3.8 achieving a drop from 40 ohms to 9 ohms. However, further lowering the pH below 3.8 results in a rise in resistance, indicating a threshold where acidic conditions become counterproductive. This research opens opportunities for broader applications of eco enzyme-treated soil in non-rod electrode systems and across diverse soil types, suggesting promising pathways for enhancing grounding systems in various environmental conditions.
