<![CDATA[This research aims to analyze students' learning difficulties in solving mathematical problems, especially in mixed arithmetic operations at the elementary school level. The method used is Systematic Literature Review (SLR), which collects and analyzes relevant previous research. The research results show that most students have difficulty in understanding questions and doing arithmetic operations, especially in the arithmetic operations section (90% of students have difficulties). Common mistakes include errors in concepts, procedures, and operations, caused by lack of understanding, inaccuracy, and confusion in the order of processing questions. Internal factors such as attitude and motivation as well as external factors such as ineffective teaching methods also affect this difficulty. This research suggests solutions in the form of improving arithmetic exercises, improving the understanding of basic mathematical concepts, using relevant learning media, as well as guidance and remedial for students with difficulties. A creative learning approach is needed to overcome this challenge.]]>

<![CDATA[This study aims to analyze the difficulties faced by elementary school students in solving multiplication problems and the strategies implemented by teachers to address them. The background of this research lies in the importance of understanding multiplication as a foundational concept for mastering more advanced mathematical operations. This research employed a descriptive qualitative approach, using interviews as the primary data collection technique. The findings revealed that students struggle with understanding multiplication as repeated addition, applying problem-solving strategies, and maintaining accuracy due to over-reliance on rote memorization without conceptual understanding. To overcome these issues, teachers implemented various strategies such as the use of interactive learning media, concrete manipulatives, game-based learning, gradual practice, and individualized guidance in collaboration with parents. These strategies have proven effective in improving students’ conceptual understanding, accuracy, and confidence in solving multiplication problems.]]>

<![CDATA[Mathematics is often viewed by many elementary school students as a difficult subject. This is because if it is only taught in the lecture method, the material is abstract and not very interesting. To overcome this, the use of interactive learning media is a promising solution. The purpose of this study was to determine the extent to which interactive media affects mathematics learning outcomes in elementary school and what factors support its success. The method used is literature study research by collecting and analyzing various related research findings. The findings of this study indicate that interactive media such as animation, educational applications, digital games and other visual media can help to better understand the material, increase enthusiasm for learning, and promote active participation in the learning process. In addition, most of the studies analyzed showed an increase in students' academic reviews after using interactive media compared to traditional learning methods. The success of using this media is also greatly influenced by teacher motivation, institutions available at school, and the suitability of the media to student needs. Therefore, it is important for teachers to choose the right media and remain innovative. This will make the mathematics learning process more interesting and easier for students.]]>

<![CDATA[The Maluku Islands are a high-poverty region in Indonesia. The region consists of 2 provinces, namely Maluku province and North Maluku province. There are 21 districts/cities in the region, with 17 regencies and 4 municipalities. The poverty rate in this region is a challenge that always wants to be studied with a socio-population approach and a mathematical statistics approach. One method or approach in analyzing poverty is Principal Component Analysis (PCA). PCA has the advantage of simplifying information from various variables to several principal components without losing much information and can overcome the problem of multiple linearity by changing variables that correlate with freely related components. The purpose of this research is to identify poverty in districts/municipalities in Maluku Islands using the PCA approach. The results showed that the components formed by the PCA method were formed in 2 factors. Factor 1 consists of GRDP (X2), Life Expectancy Rate (X3), Unemployment Rate (X4) and Percentage of Population (X6). Meanwhile, factor 2 consists of 2 variables, namely the Poverty Level (X1) and TPAK (X5).]]>
