This Classroom Action Research (CAR) was motivated by the finding of a learning motivation crisis that resulted in low participation and passivity among 25 students of grade IV at SD Muhammadiyah 3 Kuala Beringin in learning the Indonesian Language. This condition hindered the development of students' reading, speaking, writing, and listening skills. This study aimed to improve students' learning motivation through the application of Reinforcement Techniques focused on a combination of specific verbal reinforcement and a token economy in the form of active stickers. The research was conducted in two cycles, each consisting of planning, acting, observing, and reflecting stages. Data collection was carried out exclusively using observation techniques through a learning motivation observation sheet. The success indicator was set at 75% of the total students reaching a minimum scale of "Good" in all observed aspects. The results showed that in Cycle I, the success rate of students' learning motivation only reached 44% (11 students). After reflection and optimization of actions in Cycle II, the success percentage jumped significantly to 84% (21 students). This improvement proves that providing verbal appreciation that highlights effort and visual rewards in the form of active stickers is effective in fostering students' self-confidence, enthusiasm, and proactive participation. Thus, the application of reinforcement techniques successfully transformed the classroom climate to be more dynamic and convincingly improved the motivation to learn the Indonesian Language among grade IV students.

Clustering is one of the roles in data mining which is very popularly used for data problems in solving everyday problems. Various algorithms and methods can support clustering such as Apriori. The Apriori algorithm is an algorithm that applies unsupervised learning in completing association and clustering tasks so that the Apriori algorithm is able to complete clustering analysis in Uninhabitable Houses and gain new knowledge about associations. Where the results show that the combination of 2 itemsets with a tendency value for Gas Stove fuel of 3 kg and the installed power meter for the attribute item criteria results in a minimum support value of 77% and a minimum confidence value of 87%. This proves that a priori is capable of clustering Uninhabitable Houses to help government work programs.

Penelitian ini bertujuan untuk meningkatkan hasil belajar siswa dengan menerapkan model pembelajaran kooperatif tipe scramble pada materi pokok transformasi geometri di MAS PONPES Darul Qur'an tahun ajaran 2021/2022. Jenis penelitian ini adalah penelitian tindakan kelas (action research). Penelitian ini dilaksanakan dalam dua siklus. Setiap siklus terdiri dari perencanaan, pelaksanaan, observasi, dan refleksi. Data peningkatan hasil belajar diperoleh dari hasil evaluasi peningkatan hasil belajar siswa menggunakan soal esai yang diberikan kepada siswa kelas X MIA 3 yang berjumlah 32 siswa. Hasil penelitian menunjukkan adanya peningkatan hasil belajar siswa kelas X MIA 3 di MAS PONPES Darul Qur'an setelah mengikuti pembelajaran menggunakan model pembelajaran kooperatif tipe scramble. Peningkatan hasil belajar siswa dapat dilihat dari nilai rata-rata tes hasil belajar siswa siklus I dan II secara berturut-turut adalah 72,13 dan 86,55, serta ketuntasan belajar klasikal siklus I dan siklus II secara berturut-turut adalah 68,75% dan 90,63%. Dengan demikian dapat disimpulkan bahwa model pembelajaran kooperatif tipe scramble dapat meningkatkan kemampuan hasil belajar siswa AbstractThis study aims to improve student learning outcomes by applying the scramble-type cooperative learning model to geometric transformation lessons at MAS Ponpes Darul Qur'an for the 2021/2022 academic year. This study follows the classroom action research (CAR) method. This research was conducted in two cycles. Each cycle consists of planning, implementing, observing, and reflecting. Data on improving learning outcomes were obtained from the evaluation results of improving student learning outcomes using essay questions given to the tenth-grade students of MIA 3 with a total of 32 students. The results indicate that there was an increase in the learning outcomes of the tenth-grade students of MIA 3 at MAS PONPES Darul Qur'an after learning using the scramble-type cooperative learning model. The increase in student learning outcomes can be seen from the average scores of student learning outcomes tests cycles I and II respectively which are 72.13 and 86.55, as well as the classical learning mastery cycles I and cycle II respectively which are 68.75%. and 90.63%. Thus, it can be concluded that the scramble-type cooperative learning model can improve the ability of student learning outcomes.

The development of communication and collaboration skills constitutes a critical demand in 21st-century learning. However, classroom practices remain predominantly teacher-centered, limiting students’ opportunities to actively engage in scientific investigation and collaborative work. This study aims to examine the effectiveness of the Investigation-Based Scientific Collaborative (IBSC) learning model in enhancing students’ communication and collaboration skills.This research employed a quasi-experimental design involving students as research participants. The experimental group received instruction using the IBSC model, while the control group was taught using conventional methods. Data were collected through assessment instruments measuring communication and collaboration skills, observation sheets, and supporting documentation. Data analysis was conducted using descriptive and inferential statistics to determine differences between the two groups.The findings indicate that students taught using the IBSC model demonstrate significantly higher communication and collaboration skills compared to those taught through conventional learning. The IBSC model promotes active student engagement in investigative activities, scientific discussions, and collaborative problem-solving, thereby positively influencing their ability to communicate and work effectively in teams.This study concludes that the Investigation-Based Scientific Collaborative (IBSC) learning model is effective as an alternative instructional approach for developing students’ communication and collaboration skills.

Usaha Kecil dan Menengah (UKM) memiliki peranan penting dalam pertumbuhan ekonomi, namun sering menghadapi kendala dalam mengakses pembiayaan. Proses penentuan kelayakan penerima bantuan pinjaman kredit UKM umumnya dilakukan secara manual, sehingga berpotensi memakan waktu dan bersifat subjektif. Penelitian ini bertujuan mengembangkan sistem pakar berbasis metode Breadth First Search (BFS) untuk membantu proses evaluasi kelayakan secara lebih objektif, sistematis, dan efisien. Metode BFS digunakan untuk menelusuri semua kemungkinan jalur keputusan secara menyeluruh berdasarkan kriteria penilaian yang telah ditentukan, seperti kejujuran, kedisiplinan, tanggung jawab, modal awal, aset usaha, lokasi, dan stabilitas pendapatan. Sistem ini dirancang menggunakan bahasa pemrograman PHP, basis data MySQL, dan pemodelan UML. Hasil pengujian menunjukkan bahwa sistem mampu memberikan keputusan kelayakan secara tepat sesuai aturan yang telah ditentukan, serta dapat membantu lembaga penyalur kredit dalam mengefisiensikan proses seleksi penerima bantuan pinjaman.

This study aimed to develop GeoGebra-assisted interactive learning media on the topic of gradients for junior high school students that are valid and practical for use in mathematics learning. This research employed the Research and Development (RD) method using the 4D model, which consists of the define, design, develop, and disseminate stages. The trial subjects consisted of 15 eighth-grade students of SMP Negeri 1 Tanjung Pura. The research instruments included media expert validation sheets, material expert validation sheets, and student response questionnaires. The results showed that the developed media met the validity criteria based on the media expert validation results with an average score of 3.61 and the material expert validation score of 3.66. In addition, the media received positive responses from students with an average score of 3.63, indicating that it was practical for use in learning activities. The GeoGebra-assisted interactive learning media was able to help students understand the concept of gradients visually and interactively. Therefore, the developed media is feasible to be used as an alternative mathematics learning medium in junior high schools.
