The COVID-19 pandemic has had a major impact on education, forcing learning to switch to an online system to prevent the spread of the virus. However, problems still persist, especially in elementary school mathematics education, students tend to think mathematics is difficult and not very interesting. This is due to the ineffective classroom learning approach, so that many students lose interest in learning mathematics. Therefore, innovative solutions are needed that can increase students' interest and understanding of mathematics learning, such as a gamification approach for students who prefer to play. The purpose of this study is to develop a mobile application that combines a gamification approach as a mathematics learning material for elementary school students. The system concept in this mobile application is that students can work on practice questions and see learning outcomes, choose an avatar on the edit profile, and access the discussion forum available in the application. This application is designed to create an interactive, fun and effective learning experience using the ADBO (Analyze, Design, Build, Operate) method which is systematic and directed to ensure that each stage of the process provides optimal results and according to user needs with the hope of overcoming complex problems faced by students. Through the modeling used in the preparation of this application, it is hoped that it will be in accordance with its purpose, namely to provide convenience to elementary school students, from grade 1 to grade 6, to become better at learning.

Fungal infections, such as those caused by Curvularia, can interfere with the vegetative growth and reduce the quality of oil palm seedlings, particularly in the main nursery phase. One solution to improve resistance to pathogens and support vegetative growth is by applying the right foliar fertilizer. This study aimed to determine the effect of Kenfolan foliar fertilizer application on vegetative growth and the level of Curvularia infection in oil palm seedlings during the main nursery phase. The study used a Completely Randomized Design (CRD) with five treatments of Kenfolan fertilizer concentrations: 0 ml/L (P1), 1 ml/L (P2), 2 ml/L (P3), 3 ml/L (P4), and 4 ml/L (P5), each repeated three times. The parameters measured included seedling height, stem diameter, number of fronds, and the percentage of Curvularia infection. Data analysis was performed using ANOVA followed by Duncan’s Multiple Range Test (DMRT) at a 5% significance level. The results showed that treatment P4 (3 ml/L) provided the best vegetative growth, with seedling height reaching 40.07 cm, stem diameter of 1.58 cm, and an average of 4.25 fronds. Additionally, treatments P3 (2 ml/L) and P4 (3 ml/L) successfully suppressed Curvularia infection, with no infection found in these treatments. In contrast, treatment P1 (control) showed the highest infection level of 33%, while P5 (4 ml/L) increased the infection compared to P3 and P4. Based on the results, the application of Kenfolan foliar fertilizer at a dose of 3 ml/L (P4) was the most effective in improving vegetative growth and suppressing Curvularia infection in oil palm seedlings in the main nursery phase.

This study aims to determine the effect of soaking time and coconut water concentration on the dormancy breaking of oil palm seeds (Elaeis guineensis Jacq.). This study used a Factorial Completely Randomized Design with two factors. The first factor is the concentration of coconut water (A): A1 = 25% coconut water/liter of water, A2 = 50% coconut water/liter of water, and A3 = 75% coconut water/liter of water. The second factor is the soaking time (L): L1 = 30 minutes, L2 = 60 minutes, and L3 = 90 minutes. Data analysis was conducted using variance analysis and Duncan's test. The results showed that the concentration of coconut water significantly affected germination power, germination age, plant height, and the number of leaves of oil palm seedlings. A 75% concentration of coconut water produced the best dormancy breaking of oil palm seeds. The soaking time in coconut water solution also significantly affected germination power, germination age, plant height, and the number of leaves of oil palm seedlings. A soaking time of 90 minutes resulted in the best dormancy breaking of oil palm seeds. The interaction between coconut water concentration and soaking time significantly affected the germination power of oil palm seeds. This study provides important information on the optimal soaking conditions to improve dormancy breaking success, which can be used to accelerate the germination and growth of oil palm seedlings.

With the times, cash transactions that used to use cash are now turning to credit cards. However, the increasing use of credit cards presents challenges, especially in maintaining customer loyalty. Customer churn is the loss of customers within a certain period for various reasons. Logistic Regression is a machine learning algorithm that studies the relationship between a dependent variable and several independent variables and Extreme Gradient Boosting (XGBoost) is a Gradient tree-boosting algorithm that offers out-of-core learning and sparsity awareness.The purpose of this study is to compare the performance between Logistic Regression and Extreme Gradient Boosting (XGBoost) algorithms in predicting customer churn in credit card services using evaluation metrics such as accuracy, precision, recall, and F1-score. Based on the research results, it can be concluded that XGBoost has better performance in all evaluation metrics, both in terms of precision, recall, F1-score, and accuracy. Based on the research, XGBoost shows superior performance compared to Logistic Regression in all evaluation metrics.

Clean and Healthy Living behavior in schools is a set of behaviors that are practiced in the school environment, so that it is independently able to prevent disease, improve health, and play an active role in creating a healthy environment . Health education is clean and healthy living behavior using audio-visual and demonstration methods. This study aims to determine the effect of health education using audio visual and demonstration methods on the skills of clean and healthy behavior in elementary school students 5 besuki. This research method uses quasi experimental approach with two-group pre test and post test design. The population of all students aged 6-12 SDN 5 besuki as many as 95 students SDN 5 besuki, sampling techniques used purposive sampling with a sample of 77 respondents. The instruments used are PHBS, SOP, and module videos. The Data obtained from the study were analyzed using the Wilcoxon Test and mann whitney Test. The results showed that the health education group using audio visual pre-test method amounted to 88.5 post-test 30.8 in the health education group using pre-test demonstration method amounted to 89.6 post-test 31.2. Wilcoxon test results in obtaining a p-value of 0.000 in the audio-visual and demonstration groups. Mann-whitneyy test results in getting the difference score from the difference between the two groups in getting the value of p-value 0.129 with an average value in the Audio-visual group of 35.42 and 42.49 demonstration group. It is expected that respondents who have not behaved in a clean and healthy life can apply health education using effective demonstration methods because the demonstration method is practiced directly by researchers and respondents so that it can be done independently.
