This study aims to optimize the route traveled so that the transportation costs incurred by the company can be much less. This is done because the company as an agent of 3 kg LPG gas cylinders in distributing LPG gas to each base is still not optimal with irregular routes so that the costs incurred by the company are quite large. One solution that can be done in solving this distribution problem is to apply the Saving Matrix method. The Saving Matrix method is one method that can be used to determine the distribution route of a product to the area to be marketed by determining which route to take by looking at the capacity of the vehicle and the number of goods carried in order to get the shortest route and the cost for transportation incurred is small. Based on the results of the study, a distance of 100.73 km was obtained with a total initial distance of 144.29 km, with transportation costs incurred initially of Rp. 98,117.1 to Rp. 68,496.4. So, this shows that the saving matrix method can minimize distance and transportation costs.

The numeracy literacy of Indonesian students at the international level is still relatively low. This can be seen based on the results of the PISA test. In 2015, Indonesia obtained a PISA score of 386 for mathematics from each country's average score, namely 487. Low numeracy literacy can occur due to student errors in solving numeracy questions, namely conceptual and work procedure errors. Numerical Literacy is closely related to solving mathematical problems, primarily found in questions of the Higher Order Thinking Skills (HOTS) type. Therefore, no research examines numeracy skills in solving HOTS problems. This research uses a qualitative approach with a case study type. This study's subjects were class VIII MTs Negeri 5 Tulungagung students. This study used 2 data collection techniques: tests in the form of descriptions and interviews. The analysis model used is Miles and Huberman's model, which consists of data reduction, data display, and conclusion drawing/verification. The results of this study indicate that the level of numeracy ability of students at MTs Negeri 5 Tulungaguang is quite diverse, although, in percentage terms, those with moderate numeracy skills are more dominant. (1) Students with low numeracy abilities cannot fulfil all indicators of Numerical Literacy ability in solving problems, (2) Students with moderate numeracy ability can only fulfil three indicators of Numerical Literacy ability in solving problems, and (3) Students with high numeracy abilities can fulfil all indicators of Numerical Literacy ability in solving problems.

Learning mathematics has a significant role in forming the students’ attitudes and mindsets and solving problems independently. The problems students face have low mathematics learning outcomes and feel that the material they are learning is complex and the way of learning mathematics is less effective. The teacher is still the center of mathematics's learning process. Therefore, this study aims to determine the effect of Kahoot learning media on the mathematics learning outcomes of fifth-grade students at MI Unwanul Huda. The Kahoot media application is interactive and exciting, so students do not feel bored and bored in learning. This application is a game in the form of a test. The method used is a quantitative experimental method in the form of a quasi-experimental design with one group pre-test and post-test design. The saturated technique sampling consisted of class V, with 28 students. The data collection technique used is the test. The results of the hypothesis test used the t-test with parametric statistics. It is known that the average post-test of student learning outcomes using Kahoot learning media is 65.00, and the average pre-test of student learning outcomes is 37.14. So it can be concluded that there is an influence on the mathematics learning outcomes of students who use Kahoot learning media.

North Sumatra is a province that carries out import activities in other provinces to complement the shortage of goods in North Sumatra. Every month based on data from the Central Bureau of Statistics (BPS) of North Sumatra, the import value of North Sumatra constantly fluctuates. So a method is needed to show the increase or decrease in the value of North Sumatra in the next period. The method is forecasting, where forecasting is an activity that predicts something in the future, intending to get information in the next period as a decision or decision in the future. Many forecasting methods can be used, but this study uses fuzzy time series Markov Chain and fuzzy time series Lee methods. These two methods aim to obtain the best forecasting method based on the minor mean absolute percentage error (MAPE) and mean square error (MSE). In this study, the data is on the value of imports in North Sumatra taken from the Central Statistics Agency (BPS) of North Sumatra. The test results on forecasting the import value of North Sumatra show that the fuzzy time series Markov Chain is better than the Fuzzy Time series Lee based on the smallest MAPE and MSE values. The MAPE fuzzy time series Markov Chain value is 7.7467%, and the MSE value is 176,748,587. Meanwhile, Lee's fuzzy time series has a MAPE of 10.014% and an MSE value of 2,387,874,804.

This study identified the numeracy literacy skills of Almuttaqin MTS students in a rigid material. A hallmark of numeracy literacy is the capacity to apply numbers and related symbols to operations on algebraic forms, analyze data, and understand analysis findings to predict and make judgments. Tests and interviews were used to collect data, which were then analyzed through data reduction, presentation, and conclusion. Based on the findings, the numeracy literacy skills of MTS Almuttaqin students, one student (4%) is included in the excellent group for numeracy literacy, nine students (34%) are included in the excellent category, 15 students (50%) are included in the good category, and five students (11)% is included in the less category. Students with high numeracy literacy (ST) can use various numbers and symbols to solve problems, analyze information to make predictions, evaluate the findings of their analysis, and make decisions when handling the challenges of the given material. Using various numbers and symbols to solve problems and analyze information is the only marker that satisfies students with moderate numeracy literacy (SD). They have not yet reached the stage where they can make the best choices regarding their assigned content. Students with limited numeracy literacy (SR) only write numbers and are identified when completing assignments. As a result, SD and SR have not fully learned numeracy skills. The indications that were not fulfilled were caused by mistakes made by students, including not carefully recording known and asked data, choosing an inappropriate problem-solving approach, and not understanding ideas well enough to answer questions problem.
