This research aims to 1) Find out the application of these 3 methods and which method is the best in projecting the population in North Sumatra Province, 2) Find out the calculation results of the population in North Sumatra Province in the next 10 years using one of these 3 methods. The methods used are the arithmetic method, geometric method and least square method. The research results show that the least square method has the smallest standard deviation value, namely 525818.9095 compared to the arithmetic method which has a standard deviation value of 539847.056 and the geometric method which has a standard deviation value of 1571337.94. The conclusion is that the least squares method is used in calculating population projections in North Sumatra Province in 2023-2033 because it has the smallest standard deviation value and the results of population projections using the least squares method in 2023 are 15252306 and in 2033 are 16915092. Keyword : Arithmetic Method, Geometric Method And Least Square Method, North Sumatra Province.

This study discusses the optimization of the production cost of dodol using Material Requirement Planning (MRP) with a linear programming to solve the problem of optimizing production costs in the dodol pulut sari business. This study identifies the MRP model, determines the objective and constraint functions of the MRP model, then optimizes the MRP model into a linear programming using the simplex method. There are various constraint function encountered in the company by modeling them into MRP, namely the main raw materials such as pulut, sugar, coconut milk, vanilla, management time, and waiting time for orders. While the objective function is to minimize production costs. The results of the MRP optimization study with a linear programming obtained Rp. 10.368.000 and has a difference with the costs incurred by the company of Rp. 80.000. therefore, the production cost of the MRP model by optimizing the linear programming using the simplex method is more efficient and can be used to solve problems in minimizing production costs.

This research explores the role of the extended family in providing Islamic religious education to children from broken homes. The research method used is descriptive qualitative using interview and observation data collection techniques. The results of this research are that the reason extended families are actively involved in religious education is because of the busyness and indifference of biological parents, as well as to prevent children from falling into promiscuity. The process of implementing religious education carried out by the extended family is that they teach prayer, reciting the Koran, religious values, sex education, and dress ethics through direct methods, media such as animated videos, and discussions. The extended family experience shows pride in children's development, despite challenges such as laziness and child denial. To overcome this challenge, lecture methods, punishment and reward systems are used. The observation results show the active involvement of children in religious activities, as well as the implementation of an effective punishment and reward system. This research highlights the important role of extended families in providing Islamic religious education to children from broken homes. However, to increase the effectiveness of this education, further research is recommended that focuses on empowering extended families through educational management training for children from broken homes. This training can help extended families develop better skills and strategies in educating and caring for their children.

Pneumonia is one of the leading causes of death in children in the world. The World Health Organization (WHO) estimates that this disease causes 16% of deaths in children under 5 years of age worldwide. Pneumonia is included in the top 10 diseases that suffer the most every month at the RSUD dr.Tengku Mansyur Tanjungbalai, throughout 2019 there were 73 children under five years with pneumonia and 5 of them were declared dead without hospitalization. This study is useful to find out the results of the classification accuracy of the classification and regression trees (CART) for risk factors for pneumonia in children under five years. CART classification is done by dividing the total data of under-five patients with the ratio of 15% testing data and 85% learning data. The classification accuracy obtained for the prediction data was 50% with the percentage of sensitivity and specificity of 94,12% and 14,29% respectively.

Tas anyaman tali macrame merupakan bagian dari budaya global yang mencakup unsur etnomatematika dalam proses pembuatannya. Pendidikan dan budaya sangat terkait satu sama lain dalam kehidupan sehari-hari. Konsep matematika yang diterapkan pada budaya disebut dengan etnomatematika. Pemahaman mengenai pembelajaran matematika sangat dipengaruhi oleh matematika yang bernuansa dengan budaya. Jenis tas yang dibuat dengan teknik anyaman membentuk struktur yang kuat dan fleksibel. Proses pembuatan tas anyaman melibatkan penggunaan tangan atau alat bantu untuk menyusun bahan-bahan dalam menentukan pola tertentu. Penelitian ini bertujuan untuk mengidentifikasi konsep-konsep matematika yang terlibat dalam proses pembuatan tas anyaman, serta untuk mengeksplorasi etnomatematika yang mungkin terkandung dalam proses tersebut dan relevansinya terhadap pembelajaran matematika. Penelitian ini menggunakan metode deskriptif kualitatif dengan pendekatan etnografi. Data dikumpulkan melalui wawancara, observasi, dokumentasi, dan angket dengan Ibu Prihartini. Analisis data meliputi reduksi data, penyajian data, dan penarikan kesimpulan dengan uji keabsahan menggunakan triangulasi sumber, teknik, dan waktu. Proses pembuatan tas anyaman meliputi konsep-konsep matematika seperti operasi bilangan, berhitung, pengukuran, geometri ruang, aritmatika sosial, dan barisan aritmatika. Penelitian ini diharapkan dapat menjadi sumber belajar untuk meningkatkan referensi mengenai etnomatematika yang dapat digunakan sebagai materi pembelajaran dengan mengaitkan budaya ke dalam matematika.

Many factors can cause poverty such as low income, health, education and the powerlessness or inability of certain people to be able to participate in development in their country. Education is one of the most influential aspects, especially for the development of human resources. Poverty can also be measured by the ability of the community to meet their basic needs or needs in the form of food and non-food. This study aims to determine how big the impact or influence of each independent variable on the dependent variable using panel data regression method consisting of cross section and time series. The panel data regression method with a fixed effect approach to the individual effects model has a result of R2 of 99,63% where the per capita expenditure variables for basic needs and school dropout rates are factors that have a significant effect on poverty in North Sumatra Province and the p-value results from the partial test (t-test) expeniture per capita for basic needs is 4,841 1,984 and the dropout rate is 3,733 1,984.

The implementation of rules in the classroom, including the imposition of punishment (iqab), can help students develop their personalities. In this study, the 'iqab program for elementary school children at the Darul Hikmah Islamic boarding school, Asahan Regency, will be described. A qualitative methodology and phenomenological approach are used in this investigation. employing observation, interviews, and documentation studies to gather data. data analysis that includes data display, data reduction strategies, and conclusion-making. The findings of this study show that: (1) the academic guidebook for pupils serves to socialize the idea of the "iqab"; (2) The purpose of implementing the 'iqab is to educate and stimulate students, thereby motivating them to behave well, maintain discipline, and abide by the law. Penalties must also have a high priority on benefits for pupils' education; (3) The diverse backgrounds of the students, the need for repeated warnings to get them used to following the rules of the pesantren, the students' lack of awareness, and the lack of cooperation between parents/guardians and the pesantren in maximizing the implementation of the rules are all obstacles to the implementation of iqab, and (4) The pesantren asks parents and guardians of students to assist in applying 'iqab, as well as to observe and assess the implementation each time a sanction is given to demonstrate the efficacy of enforcing sanctions on students, in order to overcome hurdles to doing so.
