This study uses a relevant dataset containing anthropometric information on children, such as gender, age, birth weight and length, current weight and length, and breastfeeding status. The research stages include dataset search, preprocessing, classification, evaluation, and implementation in a local web-based prediction program. The XGBoost algorithm was chosen because of its advantages in speed, scalability, and efficiency. After preprocessing and data sharing, the model was trained and tested, resulting in 86% accuracy, 89% precision, 95% recall, and 92% F1-score. Evaluation using the confusion matrix and classification report shows that this model is quite effective in classifying stunting status.  

The Problem-Based Learning (PBL) method is a popular approach in education that allows students to develop critical thinking and problem-solving skills through solving real problems. PBL involves steps such as problem identification, research, and presentation of solutions, with a focus on students learning independently and in small groups. Although PBL is effective in improving student learning outcomes, there are challenges such as the need for teachers who are skilled in guiding students and longer time to solve problems. Characteristics of PBL include student-centered learning, teachers as facilitators, and problems as learning stimuli. The PBL strategy emphasizes the importance of starting learning with problems that are relevant to students' real lives and gives students great responsibility in their own learning process. The research method in this study uses qualitative research methods. The method used is library research.

Stunting is a nutritional problem caused by insufficient nutritional intake for a long time. The condition of failure to thrive in children under five is a result of chronic malnutrition so that the child is too short for his age. Indonesia is among the highest in stunting cases with a prevalence of 37.2% compared to other neighboring countries. Indonesia targets the stunting rate to fall to 14% in 2024, while the stunting rate in 2021 will reach 24%. The impact of stunting is an increase in morbidity and mortality rates in children, growth in body posture or height that is not optimal compared to the child's age, disruption of motor development, increasing the incidence of degenerative diseases, less than optimal learning performance so that children's cognitive and productivity are affected and that furthermore is the increase in Health costs. The Kupang City Government, in an effort to reduce the prevalence rate of stunting below 10% in 2024, is carrying out convergence work or cross-sectoral collaboration within the scope of Pentahelix (Government, PT, Private, Community and Mass Media). The foster parent program is a form of care and effort made by involving all sectors in accelerating the prevention and handling of stunting in toddlers. The sub-districts that are used as places for community service activities are Penfui and Oesapa Selatan Subdistricts, Kupang City. The foster parent program aims to help families who really need health care for children suffering from stunting and malnutrition, and this is based on a sense of care and responsibility. The Kupang Ministry of Health Polytechnic, as one of the implementations of health transformation, supports the government's program in strengthening primary health services, especially stunting, and is expected to be involved and become a team in accelerating the prevention and handling of stunting in Kupang City. The method for implementing this community activity is the Peekaboo Psychoeducational method, namely the Kiss, Hug and Give Feed method as well as providing nutritious food to children aged 6-24 months for 90 days. The results of this community service are the achievement of measurement data on children's body weight, improvements in nutritional value/body weight of children suffering from stunting and increased knowledge of the psychoeducational parenting style of the Peekaboo method to increase parents' knowledge about stunting.

In the 21st century, technological development is increasingly rapid and tends towards digitalization, when compared to a few decades ago. So, if it is not utilized, it will be something in vain. Using technology-based learning media will facilitate the learning process, so that it can improve the quality of learning and can improve students' mathematical representation skills. One of the technology-based mathematics learning media that can help students in representing mathematical models/problems is GeoGebra Software. The purpose of this research activity is to find out whether the use of GeoGebra software  media can improve students' computational thinking skills in mathematics learning. Improving students' understanding of how to show a model or mathematical problem in graph form or vice versa is one of the benefits of research. The method used in this study is Systematic Literature Review (SLR). This research method is carried out by reviewing journals in a structured manner with predetermined steps. The result of this research activity is that GeoGebra can help students understand the concept of straight line graphs in more detail with a varied and attractive appearance. In addition, for teachers themselves, GeoGebra can be used as a mathematics learning tool to create interactive learning that allows students to explore various abstract mathematical concepts.  

Computational thinking is the ability to solve problems and design systems using concepts and techniques generally associated with computers and computer programming. The aim of this research is to conduct a literature review, namely to determine the application of computational thinking in mathematics learning. The technique used is the Systematic Literature Review (SLR) strategy. SLR is a research method that aims to identify, study and interpret data in journals systematically with specified stages. The conclusion obtained from the research results is that the application of computational thinking in mathematics learning can be done using four foundations of computational thinking, namely: (1) Decomposition, namely the problem is divided into small parts, (2) Pattern recognition, namely the process of identifying patterns or sequences of problems, (3) Abstraction, namely consideration of the important parts of a problem, and (4) Algorithm, namely a series of instructions for solving the problem. Examples of its application include the use of interactive mathematics software, mathematical simulations, problem-based learning with technology, adaptive learning and the use of educational games.  

Along with the development of technology, application/software-based learning media is needed to help students understand mathematics material. This study aims to identify, review, and conclude related to the use of scratch application-based math learning media.  The method used is Systematic Literature Review (SLR). Using the Google Scholar database, articles were searched according to the topics studied in the 2019-2024 time span. The search was based on Garuda and Sinta 1-6. The results showed that the use of mathematics learning media based on scratch application optimizes students' problem solving and improves students' understanding of mathematics concepts, thus increasing their involvement and making learning more fun.

The aim of this research is to find the problems of advanced writing skills of upper elementary school students, and provide solutions. The research method used is a literature review. Based on the research results, it can be concluded that there are two factors that cause students' difficulties in writing at a high level, namely internal factors and external factors. Internal factors include students' weak motor skills, weak visual memory, low students' interest and motivation to learn, and finally students' study habits in class and at home. Meanwhile, external factors include lack of attention from parents towards students, an atmosphere at home that is less supportive, environmental conditions and finally the influence of social media. The lack of writing skills in elementary school students may also be caused by the less than optimal use of innovative learning methods. One way to optimize the writing learning process and increase students' writing motivation is to increase students' interest in writing through interesting learning models and learning media.

The learning that has been carried out so far in the school tends to apply classical learning techniques that do not pay attention to the stages in the variety of learning. For this reason, a good way is needed to learn a lesson, one of which is known as a learning technique. In this research activity, the theme of mathematics learning for school children is based on the KUMON method. This technique is considered one of the solutions that is expected to increase children's academic values and awareness in learning and train children to have independence and full responsibility in the learning process. Indirectly, when repeating the material done by the child, the child will get a reinforcement value that is more than the material conveyed Repetition is intended to provide added value in learning a new material and is implicit in the hierarchical structure of the material that has been learned so that it will be self-absorbed when the child is faced with a problem that establishes a relationship to relates the past material to the future material. the regression analysis test using simple linear regression analysis with the general form of the equation formed is as follows: Y = 0.099X + 36.823. Where the learning variable affects the bound variable of learning outcomes of 0.099 and the value of the constant when no one variable influences, it will produce a learning outcome value of 36, 823. hypothesis test proved to be accepted and the null hypothesis was rejected from the results of the calculation of the value of t obtained was t calculated 6.796 greater than t tabel = 0.697 and sig = 0.763 > sig 0.05, it can be proven that the learning variable has a positive and significant effect on the learning outcome variable.
