The problem in the Romaromi expedition which is addressed to Padangsidimpuan City, South Tapanuli Regency, Marancar District, precisely in Sugi Julu village which produces salak fruit is that the delivery of goods is done manually and irregularly where the goods are sent from the warehouse to the customer, and back to the warehouse, so it will cost a lot of time and also costs. Furthermore, to determine the allocation of consumers among existing routes, the sequence of routes that are able to go to all consumers from the specified route from vehicles that are able to pass all routes. Based on the problem in question, this study was made with a vehicle routing problem using Clarke and Wright savings or saving matrix by completing the calculation of savings measured from the many reductions between distance traveled and time used, involving nodes also making it one of the best route paths based on the greatest savings value, namely the distance traveled from the starting point to the intended end point. From the results obtained in data processing using Clarke and wright savings as many as 14 distribution routes. This shows that the Clarke and wright savings algorithm can minimize distance and also save company expenses.

One of the coffee producers in North Sumatra is Karo Regency. Currently, the growth of coffee production in Indonesia is still hampered by the low quality of the coffee beans produced, which affects the development of the final coffee production. coffee, both in terms of selecting the best coffee beans and in terms of processing and benefits. To overcome this problem requires a system that can assist in making decisions regarding the selection of the best Arabica coffee beans with association pattern rules. As for applying associative rules to the selection of the best Arabica coffee beans in Tanah Karo between item combinations so as to form an itemset combination pattern and the Apriori Algorithm. Important association rules can be known with 2 parameters, namely, minimum support (the percentage of item combinations in the database) and minimum confidence (the strength of the relationship between items in the associative rules), both of which are determined by the user. The results of data mining calculations using the Apriori algorithm, data on the assessment of Mr. RM's coffee beans with a minimum support of 25% and a minimum confidence of 75%, form seven rules for Mr. RM's coffee beans. One of the best rules is that if the selection of Normal Bean Presentation is on the Andungsari 1, Andungsari 2, and Komasti coffee varieties, then with a 100% probability the selection on Leaf Rust Resistance will also be good for the selection of Andungsari 1, Andungsari 2, and Komasti coffee varieties. The best selection combination is {BN,B,KD,A} with a 100% confidence level and has the highest lift value, namely, 3.70.

The Sipirok woven fabric industry is one of the industrial characteristics of South Tapanuli Regency in North Sumatra. In general, the challenges encountered in the industry are related to production optimization. There have been numerous research on production optimization that use mathematical methods such as the simplex method. However, the simplex technique has limits, as it only has one objective function. As a result, the Fuzzy Multi-Objective Linear Program method is employed in this study. Because Fuzzy Multi-Objective linear program includes two objective functions, maximizing profits and reducing/minimizing processing time, it can be used to tackle optimization issues in the Sipirok woven fabric company. This sort of research employs primary data, specifically interviews and direct observation at the research site, the Sipirok Woven Fabric Industry. This study's calculations were supplemented by the simplex method, which was then followed by the two-phase simplex method to generate the ultimate outcome of woven fabric manufacture. The woven fabric industry now produces 472 units of Samuel's woven fabric, with a maximum profit of Rp. 37,920,000 and a minimum processing time of 7,110 hours, where the variable value λ is 0.10 to represent the maximum degree of each objective function.

This research aims to find out how the application approach influences students' ability to solve mathematical problems using algebra material. The differentiation approach used is process differentiation. This research uses a quantitative research approach with experimental methods in class VII Budisatrya Private Middle School. This research sample consisted of two groups, namely the experimental group VII-2, 25 students who used a differentiation approach, and the control group, Class VII-1, 25 students who used the conventional approach. This research design uses Pretest – Posttest Control Group Design. Research data was collected through mathematical problem solving ability tests both at the pre-test and post-test stages. The results of the analysis using the Independent Sample t Test with the IBM SPSS program showed results with one-sided and two-sided significance of p<0.001, which means that students who used the process differentiation approach were better at solving mathematical problems compared to students who used the conventional approach. In simple terms, the use of the process differentiation approach has a significant influence on students' ability to solve mathematical problems in algebraic material. Keywords: Differentiated Learning, Problem Solving Ability

This study aims to develop a health service module based on Islamic values in children aged 4-5 years. The module development was conducted through five stages, namely analysis, design, development, implementation, and evaluation, with the application of the ADDIE model. Module validation was conducted by health, design, and language experts to ensure its feasibility and quality. The development of health service modules based on Islamic values for children aged 4-5 years proved to be effective based on the results of validation and effectiveness tests. Module validation by health, module/design, and language experts showed excellent results, with a final score above 97% from all three experts. Module implementation was conducted in two educational institutions, RA Banatus Shalih and RA Rabiatul Adawiyah, through parenting activities. The test results showed a significant increase in children's understanding of health. In RA Banatus Shalih, the pre-test average score rose from 57.5 to 93.75 with an N-Gain of 8.85, while in RA Rabiatul Adawiyah the pre-test score rose from 58.125 to 87.5 with an N-Gain of 0.70. This shows that the module is very effective in improving children's understanding of health.

Every company in the world always hopes for the maximum possible profit so that the company's life cycle runs well. For this reason, the company must be able to manage the costs used in such a way so that there is a gap between the company's expenses and income. PT. Indomarco Adi Prima is one of the companies operating in the food products sector which still finds it difficult to determine the right method for optimizing transportation costs. Therefore, this research aims to obtain optimal transportation costs at PT. Indomarco Adi Prima in the city of Palu using the Modified Distribution (MODI) method. The results of this research show that before implementing the Modified Distribution (MODI) method the transportation costs incurred by PT. Indomarco Adi Prima, which is IDR. 61,510,000 and the resulting transportation costs after using the Modified Distribution (MODI) method are IDR. 55,565,000. This shows that PT. Indomarco Adi Prima can optimize transportation costs for the distribution of food products in December 2023 with distribution cost savings of IDR. 5,945,000 or around 10.7%.
