Many parents and teachers do not care about the motor development of early childhood. This is because their paradigm only focuses on certain developments. Therefore, as a professional and good teacher, it is necessary to know what methods need to be used in developing AUD motor skills. This service aims to make AUD teachers know what learning methods can be used in the process of developing children's gross motor skills. This PKM was held at YAPIS Merauke Kindergarten and was attended by 11 YAPIS Merauke Kindergarten teachers. This activity was carried out in 4 sessions where in each session using the lecture method and question and answer discussion. In the end, teachers are expected to be able to create more varied learning methods to support early childhood development.

The context of this research is that writing skills are very important for learning, because they can train students to think, channel their desires, emotions, and express their ideas.. The use of documentary film media tells true stories about natural events in accordance with explanatory text material that tells about natural or social phenomena that can occur, such as about water, plastic which is the source of human life. The objective of this research, the researcher wants to know is there any effect of documentary film media on the writing skill of the fifth grade students of Sedatigede II Elementary School. While the research methodology used is quantitative by using a Quasi-Experimental design in the form of Nonequivalent Control Group Design. The research subjects were class V A as the experimental class and class V C as the control class at SDN Sedatigede II Sidoarjo with a total of 35 students. The data collection method used is an assessment in the form of a performance test with the task of writing an explanatory text. Using statistical analysis methods, the formulas used are normality test, homogeneity test and T-test. The test before and after using the media with the SPSS version 22 application were used. The results of this study were based on the results of the independent sample test data analysis, which showed the value of sig < 0.05, namely sig. (2-tailed) of 0.000. From these results, it was concluded that there was an effect of documentary film media on students' writing skills in the explanatory text material of fifth grade students of Sedatigede II Elementary School. This is reinforced by the significant difference in skill test scores in the experimental and control groups before and after treatment.

Face recognition is an area that is still being researched and improved for various purposes such as attendance, population data collection, security systems and others. Two methods that are often used for face recognition applications are artificial intelligence methods, especially back-propagation neural networks (ANN) and learning vector quantization. Both of these techniques are directed learning techniques that are widely used to identify distinctive patterns, namely grouping patterns into groups of patterns, making them ideal for use in facial recognition applications. In this application, preprocessing of the input image includes the detection process of scaling, grayscale, edged with the sobel and threshold methods, carried out before the image is processed in ANN. Meanwhile, the ANN approach used to identify faces involves the Backpropagation method and the Learning Vector Quantization method. The findings of this analysis are a comparison of the backpropagation neural network method and quantization of the learning vectors of face recognition used to assess variations, limitations, strengths and optimal results of the two techniques for use in facial recognition systems.    

One of the tests that measures intelligence is the IST Test with 9 sub tests, and one of the sub tests in it is the last sub test, namely ME (Merkaufgaben). This subtest measures memory. This memory is closely related to attention and the ability to remember. Memory can be said to be sharp or dull when viewed from the accuracy, thoroughness or outline, or shallowness of the memory content. Estimates, feelings, emotions, affection, hopes and desires; Also plays a role in memory function. In this research, the researcher took only one thing, namely memory ability, the sample was carried out on psychology students in semesters 4, 6, 8, totaling 98 students. Using descriptive research methods. The aim of this research is to see a picture of the memory level of Psychology students at the Main Potential University in the morning and evening students because memory is very important for their ongoing learning process. Recall or memory is a mental process that an individual has to code, store, maintain and remember information, knowledge or past experiences in the brain which can be recalled for use some time later. This research approach uses a 6 minute test, then scoring based on morning and evening groups and based on semester level. Tests are given based on each class, the morning class is carried out during the morning class at 09.00 and the evening class is carried out at 18.00. The results obtained were that the superior level of memory was found in semester 8 students at 17.3%, semester 6 at 11.2%, semester 4 at 7.14%. High average memory level at semester 8 at 13.26% and semester 6 at 9.1% and semester 4 at 13.26%. 7 is 7.14% Average memory level is located in semester 6 with 14, namely 14.26% and semester 4 with 10, namely 10.20% and semester 8, namely 3, is 3.06%. Low Average level of memory is located in semester 6, namely 7, namely 7.14% and semester 6. of 6, namely 1.12% and semester 8 of 1 with 1.02%. The highest level of superior memory based on morning and evening classes is in semester 8 of the evening class, 17.34%. These results are useful in the future and need to be improved in upgrading memory to be able to carry out daily learning activities.
