Single Tuition is a single tuition fee that is borne by each student every semester based on their economic ability while Single Tuition fee is the total operational cost of each student every semester in the Study Program at State Universities. Determination of these fees is calculated based on several criteria such as the work of the father, the work of the mother, the income of the father and mother, the number of dependents of parents, the status of parents, the vehicle owned, taxes borne by parents, and several other criteria. How to calculate and determine the single tuition fee for each student is done manually, so that problems arise that are not efficient with time and cost. Therefore, in this study, a computerized single money determination system was created by making a decision support system that was able to automatically determine the Single Tuition group. Several studies have been conducted relating to this decision-making system, including the methods used such as Multi-Attribute Decision Making, Data Mining, and AHP. In this study using a combination of Fuzzy C-Means and Simple Additive Weighting methods to determine the Single Tuition Fee. Fuzzy C-Means groups the same data into one group, while Simple Additive Weighting performs a weighted sum with a performance rating on each alternative on all attributes. The study used 13 criteria and 62 sub-criteria as parameters in determining the Single Tuition group. From the results of testing 73 test data, it is known the results that in this test the number of clusters is 8 pieces, the number of weights is 2, the iteration is maximum 100, the smallest iteration is 0.01 and the initial iteration 1. The result is known that the decision-making system succeeded in ranking with a margin error 0 - 0.01.

High school teachers who have been teaching from home (WFH) experience their challenges to teaching online. This condition causes high school teachers to adapt to the changing demands of their work. During this online learning process, high school teachers are also required to do extra-role behavior such as teaching more than needed. Therefore, this study aimed to see the effect of job crafting on Organizational Citizenship Behavior (OCB) in high school teachers during WFH. This research was conducted using a quantitative approach with 111 high school teachers who underwent WFH as respondents. Data analysis using simple linear regression analysis technique. The results of this study indicate an effect of job crafting on OCB in high school teachers who undergo WFH.

Penelitian ini di latar belakangi oleh rendahnya motivasi belajar siswa dalam proses pembelajaran yang ditandai dengan siswa yang pasif dan kurang antusias. Tujuan penelitian ini untuk mengatahui perbedaan motivasi belajar matematika sebelum dan sesudah menggunakan metode hypnoteaching. Pendekatan dalam penelitian ini adalah kuantitatif jenis eksperimen, metode penelitian ini adalah pre-eksperimental design dengan desain one-group pretest-posttest. Subjek dalam penelitian ini adalah seluruh siswa kelas III SDN 2 Kuanyar sebanyak 29 siswa yang terdiri dari 16 siswa laki-laki dan 13 siswa perempuan. Pengumpulan data dalam penelitian ini adalah dokumentasi dan angket. Uji validitas menggunakan expert judgment dan analisis indeks aiken’v. Uji prasyarat menggunakan uji normalitas dengan uji kolmogrov smirnov berbantuan SPSS V 23. Pengujian hipotesis menggunakan uji t dua sampel dependen (paired-samples t-test) berbantuan SPSS V 23. Hasil penelitian menunjukkan bahwa terdapat perbedaan motivasi belajar matematika, hasil tersebut dibuktikan dengan hasil uji t dua sampel dependeng yaitu sig < 0,05 atau 0,000 < 0,05. Disimpulkan bahwa penggunaan metode hypnoteaching berpengaruh terhadap motivasi belajar matematika siswa kelas III SDN 2 Kuanyar Kecamatan Mayong Kabupaten Jepara.

Scientific literacy is the answer to prepare students to face the challenges of the 21st century. The resulting ebooklet with the theme of food security based on scientific literacy is an alternative solution to improve students' scientific literacy skills. The food security e-booklet contains food sources, substances contained in food, and food processing methods which were compiled based on the integration of aspects of scientific literacy and problem-based learning models. The research method used was the 4D development model developed by Thiagarajan et al. (1974), which consists of define, design, and develop stages. These stages were done because this research and development were only focused on development and accuracy due to limited energy, time, and cost. The assessment was carried out using a validation sheet filled out by a team of experts. The study results obtained that the percentage of content and language feasibility aspects was 82.1%, the presentation aspect was 86.3%, and the graphic aspect was 84.1%. Therefore, this e-booklet with the theme of food security reflects students' scientific literacy and is suitable for use in science learning.
