Abstract

Adding the solar tracking control system was an attempt to increase the efficiency of solar panels. The solar tracking control system was a control system that follows the sun position. The purpose of this solar tracking system was to position the cross-section always to face the sun. The Single Axis system in solar tracking was intended to follow the sun’s angle or solar azimuth angle from the east to the west. There needed a control optimization to get the position as desired. Optimization often used artificial intelligence to obtain the automatic best optimization, such as Bat Algorithm (BA). This research compared several methods: without control, using PID control, using PID-Auto control, and using PID-BA control. The simulations showed that the smallest elevation angle deviation was found in PID-BA controller. In conclusion, PID-BA was the best controller in this research. This research could be used as a future reference with other controllers to get the most optimized controller.

Abstract

This article presents a comparative analysis of honing different talents and potential for goodness, specifically comparing various methods or approaches to developing and maximizing an individual's talents and potential for goodness. The research method used is library research. The findings indicate that humans have the potential for both good and bad tendencies. The moral teachings in the Quran emphasize the development of good traits and the avoidance of bad ones, as explained in Ibn Kathir's commentary on the purity and corruption of a person’s inner self. Humans possess two tendencies that differentiate between good and bad. Allah provides imbalance and punishment in accordance with human choices. Acts of adultery and murder are described in the Quran as grave wrongdoings that must be avoided and controlled by humans to prevent their negative consequences.   Keywords: Talent, potential, character   Artikel ini menyajikan perbandingan analisis tentang mengasah bakat dan potensi kebaikan yang berbeda, yaitu menyajikan suatu perbandingan yang menganalisis cara atau metode yang berbeda dalam mengembangkan atau memaksimalkan bakat serta potensi kebaikan seseorang. Metode penelitian yang diterapkan adalah studi kepustakaan (library research). Hasil penelitian ini adalah Manusia mempunyai kemungkinan serta kecenderungan baik dan buruk. Pelajaran moral dalam Al-Quran fokus pada pertumbuhan sifat baik dan menjauhi sifat buruk, seperti yang dijelaskan dalam penjelasan Ibnu Kasir tentang kesucian dan kekotoran batin seseorang. Manusia mempunyai dua kecenderungan yang dapat membedakan antara yang baik dan yang buruk. Allah memberikan ketidakseimbangan dan hukuman sesuai dengan keputusan manusia. Perbuatan zina dan pembunuhan dijelaskan dalam Al-Quran sebagai perilaku yang sangat buruk yang harus dijauhi dan dikendalikan manusia demi menghindari konsekuensi negatifnya.   Kata kunci: Bakat, potensi, karakter
