Apart from that, domestic rice production is relatively low, so finding an optimal distribution pattern to meet Indonesia's food consumption needs is necessary. This research aims to find the best route for rice distribution using sequential insertion and nearest-neighbor methods. The aim is to compare the two methods to determine which is suitable for distributing rice. Apart from that, comparisons are made to find the distribution route with the shortest distance and fastest time. The research results show that the optimal travel distance using the sequential insertion method is t = 1, namely 519 Km with a travel time of 779 minutes. Meanwhile, the optimal travel distance using the nearest neighbor method at r = 1 is 506 km with a travel time of 535 minutes. Thus, this problem's nearest neighbor method performs better than sequential insertion.

The research employed a research and development (R&D) method with the ADDIE development design. The developed learning materials consist of student worksheets (LKPD) and lesson plans (RPP). The lesson plans are designed to integrate Islamic religious content with various literary forms, such as critical reading, creative writing, and persuasive speaking. The research results showed that the developed learning materials have high effectiveness in improving students' literacy skills and learning outcomes. In terms of literacy skills, the average score was 84.31, indicating that the learning materials are easy to use by teachers and students. In terms of learning outcomes, the average score was 78.75%, indicating that the learning materials are effective in improving students' learning outcomes. This research contributes to the development of innovative and effective Islamic religious education learning materials that improve students' literacy skills and learning outcomes. The learning materials can be implemented in schools to improve the quality of Islamic religious education.

This problem can be solved using a fuzzy model that aims to minimize costs and minimize delivery time. This research was conducted at CV. Bebek Berkah Farm by discussing the Optimization of Egg Distribution using the FMOCIRP model. Completion of this model is done by using Winqsb software. Based on the results of calculations, the FMOCIRP model can save with an initial cost of 114,000 to Rp.84.500, and delivery time to 239 minutes from 277 minutes previously, where the optimal solution is a distribution route that provides minimum costs and time.

This type of research is quantitative research using data sources, namely secondary data. This research data was taken from clean water supply data at PDAM Tirta Silau Piasa, namely data on the volume of clean water for the period January 2021 to May 2023. From the calculation results of the prediction analysis of clean water supply at PDAM Tirta Silau Piasa using the Fuzzy Time Series Cheng method, for the amount of water supply clean water in June 2023 is 443,620, with a total predicted clean water supply from 2021 to June 2023 of 12,031,703. With a MAPE value of 3%, if we look at the MAPE which is less than 10%, the results of predicting clean water supply using the Fuzzy Time Series Cheng method produce the best prediction value.

This research is true experimental research because the researcher can control all the outside variables that affect the course of the experiment. The subjects in this study were class X MAS students Nur Ibrahimy who numbered 30 people. Data collection in this study used observation, documentation and test methods. In this study, the meeting was held for six times, namely one meeting carried out conventional learning, four times the implementation of learning with the HOTS-based mathematics pocketbook-assisted drill method and one test (post test). The data collected from the test results were analyzed using the "t" test. Based on the results of data analysis, it shows that there is an influence of the HOTS-based mathematics pocketbook-assisted drill method on student learning outcomes. This can be seen from the comparison of t table and t count. At a rate of 5% indicates that the t table is greater than t count (2.945>2.0003). Thus, it can be concluded that there is a significant influence between the HOTS-based mathematics pocketbook-assisted drill method on student learning outcomes and students learning using conventional learning.

When One of the culture applications in education is the use of teaching materials that contain cultural elements in it. In fact, it is still rare to find a learning tool that use local wisdom of local communities. One of the cultural elements that can be applied in mathematics learning is traditional market snacks that have curved side shapes. This research aims to develop an ethnomathematics-based Student Worksheet (LKPD) on the material solid figures with curved side for the 9 th grade of Junior High School and to see the feasibility of the worksheets through the validity and practicality aspects. The research model used is a 4-D model that has been modified into 3-D, which is divided into 3 steps; define, design, and develop. Research instruments include validation sheets to measure the feasibility of product, interview with subject teacher and students' response questionnaires to measure the level of product practicality. The worksheet obtained a score of 3.9 in material validation and 3.5 in media validation which had meet the very valid category. Based on the student response questionnaire, the worksheet had also obtained 76% in practicality percentage, which is in the very good category. Therefore, the ethnomathematics-based worksheet is feasible and practical to be used in the learning process.

To address this issue, innovations should be applied in the learning resources used in the teaching of mathematics, such as by developing digital learning modules. This research and development study was conducted to develop a digital module to teach students arithmetic based on the drill and practice method to improve students learning outcomes and interest in mathematics. The 4D research and development model was employed in the development of this interactive module which integrates multimedia to facilitate the variety of learning styles, including the audio and visual learning style. The digital module developed in this study showed very high validity as assessed by the media expert (3.64), content expert (3.64) and language expert (3.65). The assessment also showed that this module is practical to use (80%) and it successfully improved students' learning outcomes for social arithmetic material with N-gain score of 0.3635 (moderate improvement).
