<![CDATA[Breakfast is an activity that has benefits for school children which contributes energy and nutritional needs to support daily activities. Better memory is associated with increased glucose, indicating brain performance, especially those related to memory aspects. Consuming breakfast can improve cognitive learning and academic achievement. If children have good nutritional knowledge, they will determine which foods to consume that are healthy and have high nutrition. The aim of this research is to determine the relationship between breakfast habits and knowledge of nutritional status and learning achievement at SMPN 02 Banjar Agung, Lampung. The method used in this research uses descriptive analytics with a cross sectional approach. This research was conducted from June to July 2022. The number of samples in this research was 120 class VII students at SMPN 02 Banjar Agung who were filtered according to inclusion and exclusion criteria. The data was tested in the semester. This research showed that 100 people (80.0%) had good breakfast habits and 89 people (74.2%) had good learning achievements. Based on the results of the Chi Square test, the relationship between breakfast and knowledge of nutritional status obtained a p value = 0.040 (p < 0.05). The results of the Chi Square test regarding the relationship between breakfast and learning achievement obtained a p value = 0.000 (p < 0.05). It can be concluded that there is a significant relationship between breakfast and children's nutritional status and learning achievement.]]>

<![CDATA[Difficulty learning mathematics is a problem that often occurs, and this condition is considered to give a stigma that mathematics is a difficult subject. Various learning theories and approaches have been used, including recognizing, and exploring students' potential to find out whether there is other potential that can support their ability to understand mathematics, such as the ability to understand and evaluate oneself, also known as intrapersonal intelligence. This research aims to measure the influence of students' intrapersonal intelligence on their mathematics learning achievement by distributing questionnaires to measure their intrapersonal intelligence, as well as students' report cards as a representation of their mathematics learning achievement. In this study, the researcher used quantitative methods and found a positive and significant influence between intrapersonal intelligence on mathematics learning achievement on a strong scale.]]>

<![CDATA[Students' understanding of mathematical concepts is still relatively low, especially in data material. One of them is caused by the learning process which is still student-centered. So this research aims to find out how to increase student's ability to understand mathematical concepts using tournament-based learning with the help of panta media. This type of research is quasi-experimental with a nonequivalent control group research design. The population used was class V students in North Sumedang District with research samples from class V at SDN Sindang II as the experimental class and SDN Jatihurip as the control class. The instrument used is a test of the ability to understand mathematical concepts with description questions. The analysis technique in this research is the mean difference test (paired sample t-test and independent sample t-test) which has been tested for normality and homogeneity. To determine the increase in students' mathematical abilities, the N-Gain test was carried out. The two classes were given different treatments, namely the experimental class with tournament-based learning assisted by panta media and the control class with conventional learning. The increase in students' ability to understand mathematical concepts can be seen from the average N-Gain results in the experimental class of 0.6500 in the moderate improvement category and in the control class of 0.2591 which is classified as low improvement. The two classes have significant differences in their ability to understand mathematical concepts. It was concluded that tournament-based learning with the help of panta media can improve students' understanding of mathematical concepts.]]>

<![CDATA[Genetics is a part of biological science that contains topics such as genetic structure, protein synthesis, cell division, and inheritance of traits. Genetics is one of the most commonly found misconceptions and difficulties in learning this material due to its complex, abstract and rapid development. To overcome these problems, it is necessary to analyse TPACK and analyse various learning strategies used in teaching genetics so that it can be taken into consideration for teachers in teaching genetics in the classroom. This research uses descriptive qualitative method by collecting relevant research in the form of national and international articles available on various websites. From the results of the research, it was found that teachers have applied a variety of models, methods, and media in learning genetics. The success in this learning process certainly depends on the teacher's TPACK analysis skills so that the teacher not only pays attention to the content but also can adjust it to the needs of students.]]>

<![CDATA[Students typically have less interest in learning mathematics because it is still seen as a challenging subject. As a result, when compared to other disciplines, the pupils' mathematics understanding abilities remained below average. The aim of this study was to find out how employing visual aids, such as PowerPoint, to teach geometric shapes to students improved their mathematical comprehension skills. This kind of study uses a random subject posttest design and is therefore quasi-experimental. The population of this study consisted of students in class VIII SMPN 1 Pagelaran; the samples were drawn using the purposive sampling technique from students in class VIII C, which was the experimental class, and class VIII D, which was the control class. The t-test, homogeneity test, and normalcy test are the data analysis methods employed. With a significant rate of0.05, the testing results for the hypothesis produced tstat= 3.2 > ttable= 1.6801. This indicates that while Ha is acceptable, Ho is denied. This demonstrates how employing PowerPoint-assisted visual aids in mathematics instruction increases students' capacity for mathematical knowledge.]]>

<![CDATA[A premium reserve is the amount of funds that the insurance company needs to prepare for the payment of liability benefits when a claim occurs. One method of calculating premiums is the commissioners method which is an extension of the prospective reserve method.The main factor in the actuarial calculation is the mortality rate that can be determined using the WOOLHOUSE mortality law. This study aims to determine the size of the life insurance premiums reserve using the commisioners method and the WOLHOUSE mortality laws. The calculation of the premium reserve is linked to the determination of a person's chances of survival over a period of years of WOALHOUSE law which is then used to find the value of the insurance, the initial annuity value, the annual premium, the modified premiums based on the Commissioners method, and the amount of the premie reserve at the end of the year. The study was conducted on a 25-year-old woman who was enrolled in a dwiguna life insurance program with a 25 year liability period and a 23 year premium payment period at a 4% interest rate with a liability of Rs. 500,000,000. The results of the analysis showed that the large reserves of premiums obtained at the end of the period of liability with the Commissioners method and the WOOLHOUSE mortality law are equal to the given reservation value, so that the insurance company is prepared to give the amount of reservation promised to the policyholder.]]>

<![CDATA[Tuberculosis is a chronic infectious disease caused by Mycobacterium tuberculosis. This bacteria is commonly known as Acid Resistant Bacilli (BTA). The Hurst Exponent Fractal Dimension method was used in this work to identify the properties of time series data and fractal patterns in tuberculosis (TB) patients. The Hurst exponent method is calculated by the smallest prime factor that divides the data (pi). This fractal dimension's value is calculated using the Hurst exponent value. Time series data is classified into three groups depending on computation results: random, anti-persistence, and persistence. In the study, three data ranges (n) were obtained from the observed data, namely tuberculosis (TB) patients from July to December 2023 (174, 87, and 29). The value of the Hurst exponent obtained was 0,475 (0<H<0,5) and the value of the fractal dimension obtained was 1,525 (1,5<H<2). Based at the Hurst exponent value and fractal dimension fee, it indicates that the records is anti-persistence. Anti-persistence means that the time series data of cases of tuberculosis (TB) patients which if the data increases at one time, it tends to decrease at the next time and if the data decreases at one time, it tends to increase at the next time.]]>

<![CDATA[Vector is one of the most important subjects in mathematics, but many students face difficulties in learning vector. To find out the cause, this study is conducted to find the differences and similarities in learning opportunities presented in the vector tasks from Indonesian and Singaporean mathematics textbooks. Therefore, vector tasks from the two books are compared with the aspects of representations, contextuality, and response types. Firstly, this study finds out that the chosen Indonesian textbook provides fewer learning opportunities than the chosen Singaporean textbook in terms of vector tasks. Secondly, this study also finds out that the Indonesian textbook tends to present tasks in visual representation, while the Singaporean textbook tends to present tasks in pure mathematics form. Thirdly, this study also finds out that Indonesian textbook usually uses applicative tasks that correlate with real-life situations, while the Singaporean textbook does the otherwise. Lastly, this study also finds out that both textbooks mostly use close-ended tasks.]]>

<![CDATA[Educational statistics is a crucial course that students of Islamic Education Management must master. However, students whose majors are not directly related to mathematics often face difficulties in learning educational statistics. Therefore, it is necessary to develop a learning model that can improve students' understanding and is applicable to practical courses such as educational statistics. One promising alternative is the Project-Based Learning (PjBL) model. This study was conducted at IAIN Takengon Aceh and involved 23 fourth-semester Islamic Education Management students in the 2023/2024 academic year. The research data were collected in the form of video recordings, photos, and final project reports. The data were analyzed using qualitative techniques and presented through narrative description. The results showed that the PjBL model is effective in promoting an understanding of descriptive statistics, fostering collaboration, and providing opportunities for students to develop problem-solving skills]]>
