Abstract

Pada industri manufaktur, terutama seperti industri pakan ternak pastinya memiliki sebuah silo. Penggunaan silo digunakan sebagai tempat penyimpanan bahan untuk membuat pakan ternak. Di dalam sebuah silo terdapat sebuah mesin auger yang menggerakkan screw conveyor. Screw conveyor berfungsi untuk memindahkan bahan semi padat berbentuk halus seperti jagung. Penggunaan screw conveyor memiliki gerakan yang konstan yang mana apabila aliran jagung meningkat akan menyebabkan kelebihan muatan. Pada penelitian ini, jika kelebihan muatan akan terjadi peningkatan arus pada mesin auger yang bisa mengakibatkan korsleting atau kebakaran yang bisa mengakibatkan gagal atau keterlambatan produksi. Agar produksi berjalan lancar diperlukan sebuah sistem untuk menghindari arus berlebih tersebut sehingga mesin auger tidak mengalami trip. Dengan menggunakan sensor PZEM-004T yang dapat membaca arus pada mesin auger dan arduino uno sebagai mikrokontroler dapat mengontrol pergerakan dari sebuah tractor agar bergerak sesuai kebutuhan dan tidak menambah beban yang semakin berlebih pada mesin auger. Hasil pengujian menunjukkan bahwa sensor PZEM-004T memiliki error minimal sebesar 0% dan error maksimal sebesar 4% jika dibandingkan dengan clamp meter serta sistem yang dibuat sudah bisa mengatur jalannya tractor yang menggunakan lampu sebagai indikator sesuai arus yang ditentukan.

Abstract

Integrated Primary Education (TK Dharma Wanita) is a basic educational activity organized by and with the help of primary education officers. So, TK Dharma Wanita is a community initiative in the field of basic education, in which the village head is the responsible party. AA Gde Muninjaya (2002:169) states:“Basic education services are a form of integrated basic education services provided in primary education. Nowadays, computers are the tools used to process and create work reports, whether in the form of Word, Excel or PowerPoint data. Up to now, TK Dharma Wanita, headquartered in Sumberejo Badas Pare Village, Kediri Regency, still uses a conventional manual typewriter for reporting, which leads to many limitations that TK faces in terms of administrative operations. and data management.

Abstract

In general, photovoltaic (PV) array is not able to generate maximum power automatically, because some partial shading caused by trees, clouds, or buildings. Irradiation imperfections received by the PV array are overcome by applying maximum power point tracking (MPPT) to the output of the PV array. In order to overcome these partial shading problems, this system is employing particle swarm optimization (PSO) as MPPT method. It optimizes the output power of the solar PV array by Zeta converter. Output voltage of MPPT has high rate such that it needs stepdown device to regulate certain voltage. Constant voltage will be the input voltage of buck converter and controlled using adaptive PID. Adaptive control based on model reference adaptive control (MRAC) has design that almost same as the conventional PID structure and it has better performance in several conditions. The proposed system is expected to have stable output and able to perfectly emulate the response of the reference model. From the simulation results, it appears that PSO have high tracking accuracy and high tracking speed to reach maximum power of PV array. In the output voltage regulation, adaptive control does not have a stable error status and consistently follows the set point value.
