This community service aims at providing mentoring toward accreditation team in SDK Biloe in relation to school accreditation. School accreditation is a comprehensive assessment process of the feasibility of schools, the results of which are manifested in the form of public accountability carried out by an independent and professional institution, called BAN S/M. Assistance activities for the preparation of the 2020 Education Unit Accreditation Instrument Document (IASP) at SDK Biloe were carried out with the stages of preparation, mentoring, and reflection. The implementation of accreditation can be viewed from two things that are assessed, namely a review of administrative compliance and secondly related to the performance of the education unit for efficiency and simple and accountable implementation. After mentoring, it was found that there was an increase in the understanding and awareness of school principals, teachers, and education staff about accreditation which is one of the factors in improving the quality of education. The level of understanding is manifested by the preparation of complete documents referring to IASP 2020, namely documents on the components of graduate quality, quality of learning processes, quality of teaching staff, and quality of school management.

Microsoft excel is application that used as a learning aid in schools. The use of microsoft excel has been very commonly used in education activity. Microsoft excel is very useful to help learning process for students and educators. Microsoft excel has been known as a spreadsheet worksheet application program that is very helpful in data processing and reporting activities. It is equipped with calculation and graph creation features in the form of a number processor with various formulations to process data automatically including basic calculations, data management and data creation. SMP Kristen Kefamenanu had many students in the school that are still who do not understand and skilled in using computers. The lack of use of computers in learning materials except for Learning Information Technology and Computers (ICT) which is generally used as an extracurricular subject. The purpose of this community service activity is to introduce microsoft excel as a mathematics learning tool carried out at SMP Kristen Kefamenanu. The results of the activity can be knowing the basics of microsoft excel and finding mean values, median and single data mode with microsoft excel. At every lesson activity that has been conducted, students can show improvement in operating microsoft excel and can be seen from the test results provided.

An implementation of learning methods have to be adjusted for each course including Research Operation. This course relies on the process of critical thinking, problem solving and concept understanding. The selection of an appropriate learning methods is required to obtain an optimum learning outcome. An analysis of an appropriate learning methods can be done using Analytic Hierarchy Process (AHP). In this paper, AHP is applied to analyse and hence make decisions on appropriate earning methods for studying Operations Research course. The criteria used consist of effectiveness (K1), lecturer ability (K2), specialization (K3) and test scores (K4). While the alternatives used are the learning methods carried out, namely: Problem Based Learning (a1), drill and exercise (a2) and Blended Learning (a3). Based on the priority weight of each alternative, it is obtained that the Problem Based Learning learning method has advantages in effectiveness criteria, Drill and Exercise have advantages in student test score results and Blended Learning has advantages in the ability of lecturers. In calculating the overall weight, Problem Based Learning gives the highest weight among the Drill and Exercise learning methods and Blended Learning.

For the aspect of economic growth in NTT Province, it is necessary to understand regional characteristics in order to know the potential of each region. The aims of this study were to found the potential of regions in NTT that can increase the rate of economic growth by applying \textit{cluster} analysis, namely the Partitioning Around Method (PAM). The data used is based on data from BPS with variables of GDP, Labor Force, Unemployment, Average Length of Schooling and Investment in 2022. The results showed that optimal \textit{clusters} were obtained as many as 2 groups. \textit{Cluster} 2 shows a larger average value than \textit{cluster} 1. This means that districts/cities that tend to have higher GDP potential as well as labor force, unemployment, average length of schooling and investment are contained in \textit{cluster} 2. Meanwhile, districts/cities in \textit{cluster} 1 show a lower average.

The existence of student errors is due to the inability of the students to receive and process the information contained in the given questions. Therefore, it is necessary to conduct an analysis to find out student errors so that the results obtained in the analysis can be used by teachers to provide appropriate assistance to students, either through methods or media in learning mathematics. This study is a qualitative descriptive study. The purpose of this study was to find out how many errors were made by the eighth-grade class of Nurul Falah MTs in solving math problems according to Newman’s theory in school year 2021/2022. So that solutions to reduce errors can be found and also to emphasize which parts require a deeper understanding in solving math problems. The results of the analysis showed that the percentage of student errors in the Reading Error (RE) phase was 13.33%, Reading Comprehension (RC) phase was 42.22%, Transformation Error (TE) phase was 28.89%, Process Skill (PS) phase was 71.11%, and the Encoding Error (EE) phase was 86.67%. From the results of the analysis, it can be seen that the most errors made by students are Encoding Error, which are 86.67%.
