Kegiatan ini dimotivasi oleh keadaan anak-anak asli papua yang putus sekolah dan tidak sekolah, mendapatkan pembelajaran non formal dari unit PKBM. Metode yang digunakan adalah pendampingan pembelajaran calistung kepada anak-anak PKBM Jehova Jireh, tahapan yang dilakukan tim yakni, persiapan, dan pelaksanaan. Lokasi pengabdian berada di dalam kota Merauke, namun bila cuaca hujan, maka tim akan kesulitan untuk menuju lokasi karena kondisi tanah yang sangat berlumpur. Pelaksanaan berlangsung selama 7 kali pertemuan. Tim pengabdian menjadi pengajar dan pendamping anak-anak dalam kegiatan belajar mengajar. Kelas terdiri dari 3 kelompok belajar, dengan jumlah total anak-anak sebanyak 50 orang. Materi pendampingan yang diberikan adalah membaa, menulis, dan berhitung yang disesuaikan dengan kelompok belajar. Hasil yang diperoleh, bahwa terdapat 65 % anak usia 4-6 tahun yang mampu mengenal huruf, dan angka, 70% anak usia 7-9 tahun yang memiliki kemampuan calistung yang baik, dan 80% pada usia 10-13 tahun.

This study seeks to determine how a media video practicum based on science affects students' capacity for critical thought in class VII Junior High School 4 Satu Atap Barusjahe. Quasi-experimental research using a research design is the method used. the non-equivalent control group design for the pretest and posttest. This research’s subject is Junior High-class VII-A (Control Class/ 32 students), and class VII-B (Eksperimen Class/ 32 students). The data collection technique used a pretest and posttest. The data analysis used inferential statistics and parametric descriptive and used IBM SPSS Statistic 26. Results of posttest ability students’ critical thinking are (2,659) > (1,677), showing that there are differences in the ability of students' critical thinking. When comparing the ability of students’ critical thinking in the experiment class to the control class, it can be said that the media video practicum's impact on the ability of students’ critical thinking was much greater.

The decline in student interest in learning affects learning outcomes, thus putting pressure on lecturers to produce high-quality teaching. To create quality learning, modules that meet the needs are required; thus, research was conducted to produce interactive modules in the development of valid and practical mathematics teaching materials. This study's objective was to produce a module that is interactive in the development of valid and practical mathematics teaching materials. The ADDIE model was used in this development research, but only up to the development stage. One media expert and one material expert acted as research subjects. The results showed that the developed mathematics teaching material development module can be applied to learning in the Musamus University primary school teacher education study program. This is evident from the validation of the material by the material expert, who obtained a score of 92 placings it in the "very feasible" category in terms of the feasibility of the content and presentation. The media validation of the resulting module is in the excellent category, according to the media validation score of the media expert, which is 95. Therefore, it is recommended to use the module as one of the learning resources for developing mathematics teaching materials.

Mathematical abilities need to be possessed on the grounds of being able to equip life in solving problems regularly. The RME course bridges students to study mathematics in everyday life. The research was conducted to determine the mathematical thinking abilities of PGSD students in the RME course on number types. The type of research carried out was descriptive qualitative with the use of random sampling to determine 3 research subjects (high, medium and low mathematical abilities). The stages that were passed were the lecturer making questions, assessment criteria, conducting tests, scoring and assessment ending with data reduction assisted by MS Excel. The data obtained was that there were 16.67% students in the high mathematical ability category, 75% in the medium category and 8.33% in low mathematical ability. MS excel calculations show that the average value of students' mathematical ability is 52.78, so it is in the medium category. Students with high mathematical abilities are very good at understanding the material on odd numbers as well as irrational numbers, both on prime numbers and need guidance on prime numbers. Understanding of prime numbers is very good, good for even numbers as well as odd numbers but needs improvement in irrational numbers for students with moderate mathematical abilities. Students with low mathematical abilities have a good understanding of prime numbers, understand enough material for odd and even numbers and have no clue about irrational numbers.

The best approach to addressing this issue is necessary due to parents' lack of understanding about children's education and current needs. Therefore, it is imperative to provide services that seek to improve parents' understanding through socialization. This service was held to better inform parents of RT 08 Kelurahan Mandala Merauke about educational efforts. The participants in this service totaled 20 people, all of whom were parents of children in the school age range. The method of service carried out was mentoring with a lecture, discussion, and question and answer approach. The results of the service showed a positive influence on parents' perceptions of education for children. After the material was delivered, it was clear that parents' understanding increased. To increase parents' awareness of education for children, it is recommended that the activities carried out be continued and made into routine activities.
