Abstract

Inorganic waste is waste that is difficult to decompose, for example, plastic snacks, plastic bags, plastic/glass bottles, etc. Handling inorganic waste requires attention because wise methods are needed to manage and recycle inorganic waste properly. Because in reality, inorganic waste is the largest waste produced by humans. This can be seen from the accumulation of plastic waste around humans. Therefore, this activity aims to provide students with direct knowledge of how to process inorganic waste into valuable products. The method used in this journal is a qualitative descriptive method. This activity was carried out in class VIII I of SMP Negeri 7 Mstaram starting from 2 – 26 October 2023. The total number of students in this class is 40 students. The method of implementing this activity includes several stages, namely the problem identification stage, the action planning stage, the action implementation stage, and the final stage is turning around the results and actions. The products produced from processing this inorganic waste are handicrafts such as pencil cases, flower vases, pots, cars, and so on. Then the students' handicrafts were packaged and displayed. It is hoped that this activity can continue to be carried out and developed by the school to improve the quality of learning and improve student performance in processing and utilizing inorganic waste effectively and efficiently.

Abstract

This study examines the relationship between the ability to memorize the Qur'an and the mathematics learning outcomes of 11th-grade students at MA Putri Al-Aziziyah in the 2023/2024 academic year. Memorizing the Qur'an requires a high level of concentration, which also plays a role in enhancing brain performance. When brain cells are utilized positively and actively, brain performance improves, making students who are accustomed to memorizing the Qur'an tend to have better cognitive function. This research is a correlational study with a quantitative approach, involving 63 samples from a total of 170 students. Data was collected through oral tests and interviews and analyzed using the Pearson product-moment correlation. The results indicate that both mathematics learning outcomes and the ability to memorize the Qur'an are very good. The data shows that 57.14% of students have memorized 1-10 juz, 14.28% have memorized 11-20 juz, and 28.58% have memorized 21-30 juz. Based on the data analysis, a significance value of 0.042 < 0.05 was obtained, indicating a positive relationship between the ability to memorize the Qur'an and mathematics learning outcomes, with a correlation value of 0.257, signifying a weak relationship between the two variables.
