The problem in this study is the lack of use of media in the learning process. This indirectly affects student learning outcomes. This type of research is research and development (r&d), researchers develop miniature learning media (Windmills and Solar Panels) on alternative energy sources for grade IV Elementary School. The purpose of the study was to determine student learning outcomes using miniature media. This study took samples from 28 students of SDN MRICAN 1 Kediri City. The development model used in this research is ADDIE. The ADDIE model has five stages, namely (1) Analysis (2) Design (3) Development (4) Implementation (5) Evaluation. The data collection technique used is in the form of a questionnaire through data analysis techniques of validity, practicality, and effectiveness. The results of the research on the development of miniature learning media obtained include: (1) the development of miniature learning media for class IV alternative energy sources at SD Negeri Mrican 1 in accordance with the ADDIE development procedure. (2) the miniature media is declared suitable for use seen from: (a) the results of media validation get a percentage value of 90% and material validation obtains a percentage value of 89%, (b) the results of the teacher's practicality questionnaire get a value of 90%, (c) the results of the student response questionnaire in the trials that have been carried out, the percentage value is 91%. Based on the statement above, it can be concluded that miniature media has a significant influence on student learning outcomes on alternative energy sources.

Tujuan kegiatan pengabdian masyarakat ini adalah mengadakan seminar marketing untuk memotivasi dan menambah wawasan para pemilik usaha UMKM untuk memasarkan prodaknya melalui online marketing guna memulihkan perekonomian pasca pandemi Covid-19. Adapun metode dalam kegiatan pengabdian masyarakat ini adalah dengan melakukan survey lapangan dan analisis kebutuhan terkait permasalahan yang dihadapi serta angket survey terhadap peserta seminar. Hasil dari kegiatan seminar marketing ini adalah para responden Sebagian besar memiliki usaha lain selain bertani, diantaranya ada yang bergerak dalam bidang UMKM. Para responden ada yang sudah punya pengalaman marketing online meski sebatas melalui status whatsapp, sedangkan yang lainnya masih belum memiliki pengalaman. Para responden sangat tertarik untuk diajarkan dan didampingi dalam mencoba strategi marketing online. Kesan para responden terhadap seminar marketing ini sangat baik karena narasumber yang menyajikan materi dan memberikan pendampingan tidak bertele-tele dan mudah dipahami.

Changes in the learning process during the pandemic affected student learning outcomes. As many as 68% of students score below 75 in computational mathematics courses. These results are not comparable to learning outcomes when learning takes place offline. The results of the interviews show that students have difficulty understanding the material when learning is done online. For this reason, a qualitative descriptive study was carried out which aimed to analyze and describe students' conceptual understanding abilities in solving matrix problems using the APOS stages. The research subjects were 3 students of the informatics engineering study program who had taken computational mathematics courses and received matrix material, were in the category of students with low, medium, and high conceptual understanding, and were able to communicate their thoughts orally and in writing. Data collection techniques were carried out through written tests, interviews, and observations. The results showed that students with low conceptual understanding were able to solve matrix problems up to the object stage and made calculation mistakes. Students with a moderate understanding of concepts can solve matrix problems up to the schematic stage but are not careful in doing calculations. Meanwhile, students with high conceptual understanding can solve matrix questions up to the schematic stage, determine the correct answer, make conclusions, and reflect on the problem-solving obtained.

Kekerasan terhadap anak dan perempuan merupakan salah satu bentuk pelanggaran hak asasi manusia. Berbagai bentuk kekerasan kepada perempuan terus berkembang dalam kehidupan masyarakat, mulai dari kekerasan nonfisik atau verbal dan fisik. Hal inilah yang kemudian membuat masyarakat mendorong pemerintah untuk menetapkan Undang-Undang yang berlaku secara luas dalam rangka menghapuskan berbagai kekerasan. Rancangan Undang-undang Penghapusan Kekerasan Seksual berulang kali masuk dalam Program Legislasi Nasional, hingga kini belum terbentuk Undang-Undang yang sah sebagai tonggak penegakan keadilan yang menjadi dasar dalam memberikan sanksi pada pelaku dan memberikan perlindungan kepada korban. Oleh karena itu, metode pada kegiatan pengabdian ini yaitu penyampaian materi oleh narasumber kemudian di akhir kegiatan peserta membuat poster dengan aplikasi canva yang berisi tentang informasi UUTPKS. Dengan begitu, kegiatan pengabdian kepada masyarakat memiliki harapan untuk mencegah segala bentuk kekerasan seksual. Hal ini dilakukan dengan membuat dan menyebarkan poster melalui sosial media agar seluiruh masyarakat Kabupaten dan Kota Kediri sadar terhadap bahaya tindak kekerasan seksual. Khususnya juga mengetahui cara pencegahannya agar Kabupaten dan Kota Kediri dapat menjadi kota nol TPKS. Oleh sebab itu, perlu adanya sosialisasi UUTPKS kepada lapisan masyarakat agar dapat menjadi proteksi diri bagi anak dan perempuan.

Mathematics has an important role in the computer field and provides a theoretical foundation for people working in the computer field. The facts show that in the Informatics Engineering study program, Unisba Blitar, the selection of specializations is carried out without considering the grades of courses that teach basic mathematical skills. In fact, mathematical ability is needed by a computer expert. For this reason, research was conducted that aimed to cluster student mathematics learning outcomes. Clustering was carried out on 51 students in semester 4, through the application of the K-means clustering algorithm. The attributes used are school origin data, majors currently in high school, and student learning outcomes in informatics logic, statistics, computational mathematics, and advanced computational mathematics courses. The results show that through clustering with the K-Means Clustering algorithm, 5 clusters are obtained, starting from the highest average score, namely cluster 2 with a value of 86.81 and the lowest average value is cluster 5 with a value of 76.50. In cluster 2, it is dominated by students from SMK graduates majoring in TKJ. Meanwhile, cluster 5 was dominated by students from high school graduates majoring in natural sciences. In addition, there are findings indicating that vocational high school graduates do not always have lower mathematical abilities than high school graduates, because intrinsic motivation also influences the level of learning outcomes.
