Persamaan Schr¨odinger Diskrit Nonlinier (SDNL) dengan penambahan parameter driving merupakan model persamaan yang lebih realistis dalam memodelkanfenomena perambatan serat optik. Hal yang menarik dari Persamaan SDNL ini adalaheksistensi solusi soliton yang dimilikinya. Dalam penelitian ini dikaji tentang hampiran solusi soliton cerah intersite dari persamaan SDNL dengan menggunakan metodeaproksimasi variasional (AV) untuk dua ansatz yang berbeda, katakanlah ansatz (1)dan ansatz (2). Solusi analitik dari kedua ansatz tersebut dibandingkan dengan solusinumeriknya. Diperoleh bahwa AV sangat baik dalam menghampiri solusi soliton untuknilai konstanta coupling yang semakin kecil serta nilai parameter driving yang semakinbesar. Hasil AV dari kedua ansatz juga menunjukkan bahwa hampiran solusi yang diperoleh sama bagusnya dalam menghampiri solusi numeriknya.

PT XYZ, engaged in the financial industry, has a target to become a leading company in Southeast Asia and has been supported by more than 200 million customer data in its core system. This huge amount of data is expected to create business opportunities, build a risk-aware culture, and increase supremacy in the business strategy of PT XYZ. These things can be achieved if the data used is of good quality data. In fact, found anomalies in a large number of customer data. To get recommendations for improving the quality of customer data, it is necessary to assess the quality of customer data. The customer data quality assessment in this study uses the method introduced by Loshin (2011). Loshin’s Data Quality Management Model (DQMM) adopts a capability maturity level model in building its characteristic matrix. Maturity levels obtained are 3.6 (expectations), 3.6 (dimensions), 4.4 (policy), 3.8 (procedures), 4.2 (governance), 3.8 (standardization), 4, 2 (technology), and 3.8 (performance management). Regarding the expectation that senior management can achieve the highest level of data quality, 9 strategic recommendations were produced 9 strategy recommendations were submitted to PT XYZ is the result of mapping between criteria that have not been met with data quality management activity in Data Management Body of Knowledge (DMBOK) version 2.0. Measurement and monitoring of good data quality is the most influential recommendation for PT XYZ.

Mathematics is one of the most essential basic sciences because it closely relates to everyday life and the development of other disciplines. It should be taught at every education level, likewise for Islamic boarding school students. In addition to having extensive religious knowledge, students must also have increased thinking, logic and reasoning. In addition, mathematics is also an essential tool in studying several topics of Islamic law, such as inheritance law and zakat. Therefore, mathematics must be taught in the education and teaching curriculum at the Islamic boarding school, including the As-'Ashry Islamic Boarding School. One of the obstacles the Al-'Ashry Islamic boarding school faces in teaching mathematics is that students need more interest and motivation in learning mathematics. Therefore, this community service activity was carried out to increase the interest and motivation of students to learn mathematics. The activity was held on December 7, 2022. The activity was carried out in two forms: a motivational lecture and a math puzzle called Magic Square. Based on the evaluation carried out by the community service team, it was evident that the students were interested in the activities carried out. Students were fully involved in every activity carried out.

Numerical literacy is an ability that requires an understanding of basic mathematical concepts and skills. Private Integrated Islamic Junior High School (SMPS IT) "Karakter Anak Shalih" (KAS) has not implemented the Minimum Competency Assessment (MCA) of the 2022/2023 school year, which will be held in 2023. The preparations for MCA implementation should be started in 2022. One of the problems schools encounter is how to prepare the students to conceive numeracy literacy for MCA. The Community Service Activities (CSA) of the Department of Mathematics and Data Science of Universitas Andalas aims to accompany teachers and students to increase students' understanding of basic concepts and skills in mathematics, providing socialization and assistance to teachers and students regarding numeracy literacy knowledge, and supporting schools to improve learning process services. Those activities were carried out in three main stages, namely, the preparation stage, the implementation stage, and the activity evaluation stage. The results of this CSA activity were evaluated by observing the students' understanding of mathematical concepts, numeracy literacy, and improving services that support the learning process. Based on the CSA activities, it was concluded that mentoring activities must be continued to assist schools in dealing with MCA.

By current global needs, students are expected to be able to adapt to a rapidly changing world and participate actively in society. Students must become lifelong learners who need reading literacy and numeracy literacy competencies. Literacy Numeracy, often called numeracy, can be interpreted as the ability to apply mathematical concepts and skills to solve practical problems in everyday life. Starting in 2021, this ability will be measured through the Minimum Competency Assessment (AKM) aimed at classes V, VIII, and XI. The aim is to obtain information about the quality of a school so that it becomes a basis for improving the learning process in that school, especially concerning students' numeracy and literacy abilities. The problem faced by the Shalih Children's Character IT SMPS (KAS) is a lack of guidance on students' numeracy literacy skills needed to take AKM. Therefore, the Service Team from the Department of Mathematics and Data Science felt it necessary to carry out service at SMPS IT KAS as a continuation of the guidance that had been carried out in the previous year. The method used is to apply the Contextual Teaching Learning model, which helps teachers link learning material with real life and encourages students to connect their knowledge with application in everyday life. It is hoped that implementing this service can help teachers guide students in preparing for AKM in the following year.
