The concept of social arithmetic is widely applied in various real life contexts. However, many students experience difficulties in learning and understanding the concept of social arithmetic. This is because learning in class generally focuses on memorizing formulas and does not involve students building their understanding independently. In general, mathematics activities are also presented in routine problems in which the students operate the numbers listed in the questions into mathematical formulas. Therefore it is necessary to apply a learning that encourage students to involve actively and to think critically and analytically in learning, so that they are able to build their understanding independently. In addition, learning resources are also needed to present mathematical activities based on real-life contexts and facilitate student centered learning. Learning model that is relevant for achieving this goal is inquiry-based learning, and learning resources that can be used are Student Worksheets (LKPD). Therefore this study aims to produce valid and practical inquiry-based worksheets on concept of social arithmetic for seventh grade students. This study is a Research and Development (RD) study and applies ADDIE model which consists of 5 stages: analysis, design, development, implementation, and evaluation. The results show that the LKPD meet valid and practical criteria, and the results of the learning tests show that the LKPD has a potential effect on conceptual understanding skills and could be used in learning.

Project-based learning is an approach that is able to facilitate authentic learning. Authentic learning as an experiential process that prepares future educators can help the development of necessary teaching skills. Assessment of project-based learning is required to evaluate how it successfully promotes students’ learning. A survey was conducted to assess students’ perspectives on the implementation of project-based learning. Undergraduate students who enrolled in a mathematics learning strategy course at a faculty of teaching training at a university participated in the survey. Student samples responded to the questionnaire based on their video production assignment project experiences. The collected research data were then analyzed descriptively. Data analysis results suggested that project-based learning positively impacted students’ learning, motivation, and performance. As a result, future research and learning can investigate and implement project-based learning in greater depth.

PT. Multiagro Sumatrajaya adalah perusahaan yang bergerak di bidang pengolahan minyak kelapa sawit. Menurut sumber dari perusahaan, permasalahan yang sering terjadi adalah bahan baku yang cukup intens mengalami perubahan ketika musim panen. Perubahan ini menyebabkan penumpukkan kelapa sawit yang mengakibatkan naiknya harga simpan perawatan kelapa sawit di gudang. Hal ini menyebabkan kekurangan dan kelebihan minyak kelapa sawit. Akibat dari pemesanan atau pembelian yang kurang efesien dan efektif yang dapat mempengaruhi proses produksi crude palm oil (CPO). Tujuan dari penelitian ini untuk meminimalkan total biaya persediaan minyak kelapa sawit sebagai bahan baku minyak. Metode yang digunakan adalah continuous review system (CRS), yaitu metode persediaan yang memantau apakah pesanan R sudah benar dan ukuran pemesanan atau jumlah pesan Q untuk setiap pemesanan selalu benar. Maka, berdasarkan hasil analisis metode CRS diperoleh bahwa total biaya penyimpanan minimal sebesar Rp 362.029.346.319. Sedangkan menurut perhitungan perusahaan sebesar Rp 362.295.973.755, sehingga menghasilkan penghematan biaya sebesar Rp. 266.627.439 dengan persentase penghematan biaya sebesar 0,07% dari total biaya metode persediaan perusahaan atau keadaan sebenarnya dari perusahaan. Metode pengendalian persediaan terbaik dalam pengambilan keputusan untuk pengendalian persediaan adalah metode CRS dikarenakan total biaya persediaan yang dihasilkan oleh metode CRS lebih kecil dibandingkan metode yang digunakan oleh perusahaan.
PT. Multiagro Sumatrajaya是一家专门从事棕榈油加工的公司。根据该公司的消息来源，最常见的问题是在收获季节发生强烈的原材料变化。这些变化导致油棕的积累，导致价格上涨，将油棕护理储存在仓库。这导致油棕的短缺和过剩。由于订单或购买不那么有效，可能影响原油(CPO)的生产过程。这项研究的目的是将油棕作为原料的总成本降至最低。使用的方法是连续审查系统(CRS)，即监控订单R是否正确、订单大小或每次预订数量Q消息的供应方法一直是正确的。因此，根据对CRS方法的分析，总储备金成本为362029346319卢比。而根据该公司的计算，即36295,97755卢比，因此节省了266,627.439卢比的成本，其成本比公司股票或实际情况的总成本高出0.07%。在决定控制库存方面，最好的存货控制方法是CRS方法，因为CRS方法产生的总成本比企业使用的方法要小。

Teknik sampling yang digunakan adalah purposive sampling sehingga sampel yang dipilih adalah mahasiswa sebanyak 124 mahasiswa semester 3 tahun ajaran 2022/2023 yang mengambil mata kuliah Probabilitas. Teknik pengumpulan data yang dilakukan adalah dokumentasi instrumen tes dan jawaban tes mahasiswa. Data yang diperoleh diolah menggunakan program Quest, dianalisis berdasarkan teori tes klasik, dan selanjutnya dideskripsikan. Instrumen tes yang dianalisis sebanyak 15 butir soal pilihan ganda dengan 5 pilihan jawaban yang memiliki 1 jawaban benar. Tingkat kesulitan butir soal pada soal UTS Probabilitas yaitu sedang sebanyak 4 butir soal atau sebesar 33,33% dan sulit sebanyak 11 butir soal atau sebesar 66,67%. Berdasarkan karakteristik estimisasi reliabilitas, estimasi reliabilitas subjek dengan koefisien 0,67 (tinggi) dan estimasi reliabilitas butir soal dengan koefisien 0,89 (sangat tinggi). Distraktor pada semua butir soal sebanyak 15 butir dapat berfungsi. Setelah mendapatkan data berdasarkan karakteristiknya, peneliti dapat mengetahui materi yang sulit bagi peserta tes, memberi masukan kepada peserta tes tentang kemampuannya dalam menguasai materi pada materi yang diujikan, dan pembuat soal dapat memperbaiki penyajian materi pada materi yang sama untuk semester berikutnya.Kata kunci: Butir soal, instrumen tes, kualitas, ujian tengah semester

Sometimes our smartphone's internal storage is complete, and we must download an application that is very necessary at that time; this is where numeracy plays a role in solving this problem, namely the way we download the desired application with a complete smartphone's internal storage. This study aims to produce valid and practical PISA-type questions and activities using a smartphone context and potentially effective on students' numeracy skills. This design research-type development study comprised a preliminary and formative evaluation phase consisting of the design stage, self-evaluation stage, expert review stage, one-to-one stage, and small group stage. This research used question grids, question cards, assessment rubrics, lesson plans, PISA-type questions, and student activity sheets as its tools. This study was initiated owing to the insufficient numeracy skills of Indonesian students. This study focuses on seventh-grade students at secondary school number 59 Palembang, Indonesia. The qualitative findings of this research are based on field data collected through walkthroughs, observations, tests, interviews, and document reviews. This research yielded PISA-type questions and activities, namely four activity questions and six evaluation questions with smartphone context that seventh graders may utilize to develop their numeracy abilities. In conclusion, PISA-type questions and activities in the context of smartphones can be used in classroom learning to strengthen students' numeracy skills.

This research is aimed to design learning environment in which teacher can create a learning process in develop their reflective practices. Gending Sriwijaya traditional dance, which is familiar with culture in South Sumatera Indonesia, can be as a starting point for context in geometry translation. Applying The Indonesian Realistic Mathematics Learning Approach (PMRI) is one approach that uses contextual. The research used design research consisting of preparation of the experiment, design experiment and retrospective analysis. This research data were collected through classroom observation, documentation, interview, and field notes. The result of this research tries to establish that reflective teaching practice is a tool to makes room for teachers to critically examine any assumptions regarding acceptable objectives, methods, problems and solutions. By reflecting, conducting analysis, and coming to conclusions about what has occurred, the teacher might indirectly learn about the benefits and drawbacks of applying what they have learned. Collaborative learning supports and enhances learning by engaging groups which work together to solve problems, complete tasks, or learn new concepts. Students who have more ability help less-able students. On the other hand, less-able students ask for help from more-able students.
