Abstract

This study aims to analyze students' conceptions of reaction rate topics using the three-tier multi-representation test. Based on the characteristics of reaction rates concepts that involve the understanding of multiple representations, it is essential to analyze student conceptions that include multiple representations, namely macroscopic, microscopic, and symbolic. A three-tier diagnostic test can be done to assess students' conceptions, with the questions given in the first tier presented with macroscopic, microscopic, or symbolic representations according to the characteristics of the concept in question. This research uses a descriptive quantitative method conducted at Madrasah Aliyah Negeri 2 in Palu City, Central Sulawesi. The subjects of this study were 50 students consisting of 28 female students and 22 male students. It was determined by random sampling technique. Instrumentation used a three-tier representation test with 15 multiple-choice questions. Validation of instruments showed that the questions were feasible and fell into the high category. The findings reveal that only 29 % of students know the concept, categorized as low. Additionally, 40 % of students were identified as having misconceptions, placing them within the medium category, while 31 % of students exhibited not knowing the concept, also classified in the medium category. Symbolic representation emerged as the most challenging representation for students, with 35 % failing to comprehend it, categorized as medium. Furthermore, among students with misconceptions, symbolic and macroscopic representations were the most problematic, collectively accounting for 34 %, also classified as medium. These results underscore the need for targeted instructional strategies to address specific areas of difficulty and improve overall conceptual understanding.

Abstract

Sandimas Group is a trading airline that is a leading supplier of building materials throughout Indonesia. This building materials trading company markets various granite tile and sanitary products. But unfortunately, this trading company still has a problem, namely that it is still difficult to ensure the quantity of supply of products that customers really like. This problem can be solved with a system that can identify the best-selling products from various product groups. The aim of this research is to find out the right and appropriate product supply so that there is no buildup of product in the warehouse. This can be seen based on the clusters that have been formed. The formation of clusters to group merchandise products in this trading airline uses the K-Means Clustering algorithm. This algorithm can perform calculations accurately. This research is expected to be able to answer this problem correctly based on the similarity of the data. The application of the K-Means Clustering algorithm at the Sandimas Group is by collecting known product supplies in the sales transaction recap for 1 period in 2022. The results of calculating the K-Means Clustering algorithm from 15 known products are 5 products which are included in clusters 1, 6 products are included in cluster 2 and 4 products are included in cluster 3. This cluster can be seen based on the similarity of the data, namely cluster 1 is formed where buyers really like the price in the range of IDR 152,640 to IDR 225,000, cluster 2 is formed where customers quite like the product price in the range of IDR 455,896 to IDR 530,000 while cluster 3 was formed where customers liked product prices ranging from IDR 217,000 to IDR 252,000.

Abstract

Salak seeds have a reasonably high cellulose content. This suggests that salak seeds can be used as a raw material for producing activated charcoal to refine used cooking oil. This study aims to determine the effectiveness of refining used cooking oil using active charcoal adsorbents derived from Salacca zalacca seeds. The methods used to determine free fatty acid levels and peroxide values are the acid-base and iodometric titration methods. This study will observe several variables that affect the adsorption process, namely the mass of activated charcoal and the contact time of used cooking oil. The results showed a decrease in free fatty acids and peroxide number, and the colour of the oil became brighter with increasing adsorbent and contact time. The best results were obtained at a mass of 15 grams and an adsorption time of 120 minutes. Based on the quality requirements for cooking oil as specified in SNI 3741-1995.
