Abstract

As the smallest unit of life, a person has the ability to function independently of himself to maintain his survival. The smallest entity that has the ability to reproduce and divide is a cell. The two types of cell architecture are eukaryotic and prokaryotic. Plant cells will also be discussed apart from that. Plant cells will be closed separately even though they are eukaryotic and have special organelles. Every biological process is cellular and controlled. As a result, as long as all basic needs are met, the cell can operate independently. Organisms, or living things, consist of many cells (multicellular) or one cell (unicellular), such as bacteria, archaea, fungi, and protozoa. Viruses are microscopic organisms that exist outside cells. Viruses are obligate parasites because viruses do not have the cellular machinery needed for reproduction, so viruses can only reproduce in living things by entering and exploiting their cells.

Abstract

In the rapidly evolving era of technology, the need for innovative and effective Islamic education for young children is becoming increasingly pressing. Therefore, this research aims to explore the effectiveness of the film "Rara and Nussa" as a means of Islamic education for young children in the digital age. Against the backdrop of changing dynamics of life and the need for innovation in Islamic education, this research presents an analysis related to the validity and reliability of the research instrument as well as the effectiveness of the film. Through data collection using questionnaires distributed to 50 respondents, and analysis using SPSS software, the research findings indicate that the film "Rara and Nussa" has a strong correlation with understanding Islamic values, reinforces moral values, and enhances the quality of Islamic education. Statistical analysis results show high correlation values and convincing significance, as well as instrument reliability that can be trusted. This conclusion confirms that the use of appropriate research methods and accurate data analysis can strengthen research findings regarding the effectiveness of films as a means of Islamic education for young children, providing a significant contribution to the development of Islamic education in the digital era.

Abstract

Market Basket Analysis (MBA) is an analytical technique used to identify relationships between items in purchasing transactions. This notebook uses retail transaction datasets and the Apriori algorithm to discover hidden associations and patterns that retailers can leverage in optimizing marketing strategies, store layouts, and product recommendations. Through initial data processing, data exploration, and application of the Apriori algorithm, this analysis succeeded in identifying various significant associations between items that are frequently purchased together. The results provide valuable insights for retailers to develop targeted promotions and improve customer shopping experiences, while emphasizing the importance of selecting the right parameters to obtain accurate and relevant results.

Abstract

Adsorption is a separation process on a particular substance based on the affinity of a compound to a solid. The adsorption process requires an adsorbent as an absorbent material and an adsorbate as an absorbed component. The adsorbent that is often used to absorb Cu2+ ions is silica gel. Silica gel is a rigid gel that is amorphous. In silica gel there are two main bonding groups, namely siloxane and silanol groups which cause silica gel to easily absorb polar molecules, especially water. The purpose of this research is to get the best mass of silica and the effect of the initial concentration of Cu ions on the final concentration of Cu metal. In this study, two operating conditions were varied, namely the mass of silica gel adsorbent 0.4 grams; 0.6 grams; 0.8 grams; 1 gram; 1.2 grams and the initial concentration of Cu metal 3 ppm; 4 ppm; 5 ppm; 6 ppm; 7 ppm. The results of this study showed that the silica content of bagasse ash was 70.97% with a surface area of 283.802 m2/g. The best result of this study reduced the content of copper metal (Cu) by 88% in the condition of silica gel mass of 1.2 grams. The adsorption isotherm shows that the data is more in line with the Freundlich equation. The resulting equation is y = 0.4268x + 0.4969 with an R2 value of 0.9837.

Abstract

Students need to have mathematical problem-solving skills to solve mathematical problems both in school and in real life. But in reality, students' mathematical problem-solving skills are still low. This study aims to analyze students' mathematical solving abilities from the perspective of gender differences, so that teachers can find the right solutions to improve students' abilities. This research is a qualitative research. The instruments used in this study are test questions and interview guidelines. The subjects of this study were three students taken from 20 students in grade VIII MTs Azzainiyah II. The subject consists of one student representing each of the high, medium, and low abilities. The results of the study showed that the mathematical solving ability of female students was better than that of male students. In the group of high-ability students, female students can meet all four indicators of the mathematical problem-solving stage, while male students can only meet the three indicators of the mathematical problem-solving stage. In the group of moderate-ability students, female students can meet three indicators of the mathematical problem-solving stage, while male students can only meet two indicators of the mathematical problem-solving stage. In the group of low-ability students, female students can meet two indicators of the mathematical problem-solving stage, while male students can only meet one indicator of the mathematical problem-solving stage.
