Abstract

The distribution system is one of the most important elements to be able to distribute electrical energy from power plants to consumers. Tanjung Balai Karimun, Kepulauan Riau is an island near the island of Batam. PT Karimun Power Plant has built a plant with a total capacity of 7.5 MW consisting of 5 machines with a capacity of 1.5 MW each. This research is aimed at the appropriate distribution system to be applied there. Medium voltage air duct is one of the existing systems, and is suitable to be applied in Zone II Tanjung Balai Karimun Riau Islands. The cross section size used in the calculated conduit is 100 mm² in the upstream and 16 mm² in the downstream. These conveyors are supported by a pole with a height of 12 m and with a distance between the poles as wide as 100 m. in this system there is also a transformer with a capacity of 160-4000 kVA. This system was tested using ETAP software and produced data that the available generator was not enough to carry the burden in Zone II Tanjung Balai Karimun. Due to inadequate power generation, the long-term solution is to increase the number of plants while the short-term solution is to reduce the burden to be carried.Keywords.

Abstract

It requires a tool in a high voltage laboratory to convert the voltage from a PLN of 220 VAC to a DC high voltage. The study aimed to evoke DC high voltage using the flyback method of coils with the Pulse Width Modulation (PWM) technique raised by microcontrollers within the Arduino system and observed the effect of frequency on spark gaps posed by voltage output from flyback transformers. In this study it has been successfully at a 7.90 kV–58.70 kV DC output voltage using Flyback transformer converters and using PWM techniques. The results of the study showed that with frequencies of 100 Hz, 200 Hz, 300 Hz, 400 Hz, 500 Hz, 600 Hz, 700 Hz, 800 Hz, 900 Hz, 1000 Hz, 2000 Hz, 3000 Hz, and 4000 Hz, yielded output voltages according to Ritz's spark gap theory of 7.9 kV, 1700 kV, 17.00 kV, 24.V, 24.00 kV, 24.V, 24. 24.00 kV, 31.35 kV, 31.35 kV, 39.20 kV, 39.20 kV, 48.35 kV, 48.35 kV, 58.70 kV, 58.70 kV. This test showed that with duty cycles of 50% organized using Arduino the higher the frequency the higher the output voltage generated as the above is listed. Diperlukan suatu alat di laboratorium tegangan tinggi untuk mengubah tegangan dari PLN sebesar 220V AC menjadi tegangan tinggi DC.  Penelitian ini bertujuan untuk membangkitkan tegangan tinggi DC menggunakan metode flyback dari kumparan dengan teknik Pulse Width Modulation (PWM) yang dibangkitkan oleh mikrokontroler di dalam sistem Arduino dan mengamati pengaruh frekuensi terhadap spark gap yang ditimbulkan oleh keluaran tegangan dari transformator flyback. Pada penelitian ini telah berhasil di dapatkan tegangan keluaran sebesar 7.90 kV – 58,70 kV DC dengan menggunakan konverter transformator Flyback dan memakai teknik PWM. Hasil penelitian menunjukkan bahwa dengan frekuensi sebesar 100 Hz, 200 Hz, 300 Hz, 400 Hz, 500 Hz, 600 Hz, 700 Hz, 800 Hz, 900 Hz, 1000 Hz, 2000 Hz, 3000 Hz, dan 4000 Hz, menghasilkan tegangan keluaran menurut teori spark gap Ritz sebesar 7.9 kV, 17.00 kV, 17.00 kV, 24.00 kV, 24.00 kV, 31.35 kV, 31.35 kV, 39.20 kV, 39.20 kV, 48.35 kV, 48.35 kV, 58.70 kV, 58,70 kV. Pengujian ini menunjukkan bahwa dengan duty cycle sebesar 50 % yang diatur menggunakan Arduino semakin tinggi frekuensi semakin tinggi tegangan keluaran yang dihasilkan seperti yang tertera di atas.

Abstract

Sampah merupakan salah satu masalah yang ada di sebuah negara. Indonesia menepati urutan ke-2 pemasok sampah terbesar di dunia setelah China. Pembangkit listrik tenaga sampah (PLTSa) merupakan salah salah satu pembangkit dengan energi terbarukan. sampah yang akan digunakan sebagai bahan bakar PLTSa akan di keringkan secara alami dengan penimbuan di ruangan terbuka dan pencacahan dengan crane selama lima hari. Perancangan system pengering sampah menggunakan gas sisa pembakaran dan konveyor otomatis ini bertujuan mempersingkat waktu penyimpanan sampah dan ingin menigkatkan produksi dari Pltsa Bantargebang. Metode penelitian yang digunakan adalah studi literatur. Adapun hasil yang diharapkan dengan menggunakan sistem ini sampah dapat kering hingga kadar air yang tersisa 20% dengan nilai kalori 2000 kkal/kg. Garbage is one of the problems that exist in a country. Indonesia is the second largest supplier of waste in the world after China. The waste power plant (PLTSa) is one of the plants with renewable energy. The waste that will be used as fuel for PLTSa will be naturally dried with an open hoarding and crushing with cranes for five days. The design of a waste dryer system using combustion residual gas and automatic conveyors aims to shorten waste storage time and wants to increase production from PLTSa Bantargebang. The research method used is the study of literature. As for the expected results using this system the garbage can dry up to the remaining 20% water content with a caloric value of 2000 kcal / kg. The method used is to collect data and visit observations to the Bantargebang PLTSa. The results of this research are the drying process becomes shorter and the heating value increases so that it can produce with 700kW.
