Abstract

Hydroponics is an agricultural system that requires electricity to drive water pumps that flow irrigation, and solar panels are tools to convert solar energy into electrical energy. The drawback of installing solar panels so far is static so that the power received is not optimal, considering that the sun is always moving around the earth. In this case a solar panel with a solar tracker system is used as a source of electrical energy for the water pump. The purpose of using a solar tracker on this hydroponic solar panel is to optimize the absorption of the energy received by the solar panel. The method used in this research is the method of literature study and experimental research. The research was conducted from March 4 - April 15 2023 from 07.00 - 18.00 WIB with 1 day of static position testing each, and 1 day of solar tracker solar panels every day. The total power obtained during the test was 2823.31W on the solar tracker system after deducting the power consumption of the solar tracker system, while in a static position the power obtained was 1843.71W. On the solar tracker system it takes 3 Hours 54 Minutes to charge the battery after the battery power is used for 13 hours. Meanwhile, in a static position it takes 6 hours. The conclusion from this study is that the solar panel solar tracker system in hydroponics is capable of producing a power increase of 53% compared to hydroponic solar panels in a static position.

Abstract

Analytical research on improving calistung abilities was carried out because of complaints that emerged from the school that there were still many students in class VI who were still weak in calistung. This research was conducted with the aim of describing the implementation of tutoring activities to determine learning outcomes and improve the calistung abilities of class VI students at SD NU Pemanahan. This research uses a qualitative descriptive research method. With a population of 10 students in class VI of SD NU Pemanahan. Data collection techniques in this research used interviews, observation and documentation. Interviews were conducted with class VI teacher Mrs. I, to determine the development of students' calistung abilities when learning in class. Meanwhile, observations were made during the guidance process. Documentation in the form of photos, videos and student evaluation results over a period of time after guidance. The data analysis technique is carried out through three stages, namely data reduction, data presentation, and drawing conclusions. In implementing the guidance process, students are divided into 3 categories, namely less fluent in calistung, less fluent in reading and writing, and the third less fluent in arithmetic. Grouping is done to make it easier to provide guidance. After the end of the guidance process, a test of the abilities of each group was carried out and the results showed that they had improved. From the results of interviews with teachers, there was a significant improvement in the class during the learning process after the guidance process was carried out. So there was an increase in calistung ability in students who were given tutoring treatment.
