The Industrial 4.0 Era encourages educators to be able to apply information technology in the learning process. One application of technology in the learning process is the use of learning videos. Especially during the current Covid 19 pandemic that applies online learning, videos can be an alternative source for learning. However, in reality, many teachers in Indonesia cannot make learning videos. Online learning is currently mostly only in the form of providing material from textbooks, discussions via WA, visiting students' homes to give assignments, and so on, so it is not optimal. Therefore, this training activity aims to train teachers in making learning videos so that teachers have other alternatives as a source of student learning. This activity is in the form of training in making and editing videos using the Bandicam application, Microsoft PowerPoint 2013, and the Kinemaster application. The results of this activity are participants/teachers for the Bandicam application with a 100% success rate, Microsoft PowerPoint 2013 100% success rate, Kinemaster the first stage success rate 70%, then the second stage 100%.

AbstrakPenelitian ini bertujuan untuk mengembangkan e-katalog sebagai sistem informasi pemasaran kopi sapit berbasis web serta untuk mengetahui kelayakan dari e-katalog pemasaran kopi sapit.

Didapatkan persentase kelayakan dari ahli media sebesar 71% dengan melihat 3 aspek yaitu tampilan media, functionality, dan komunikasi visual sehingga dinyatakan "Layak". Persentase kelayakan dari ahli materi sebesar 93% dengan melihat 3 aspek yaitu desain isi, isi, dan bahasa komunikasi sehingga dinyatakan "Sangat Layak". Hasil uji coba pada pengunjung e-katalog yang berjumlah 20 orang diperoleh hasil persentase kelayakan sebesar 67% dengan melihat 4 aspek yaitu kegunaan, kualitas informasi, kualitas interaksi, dan kepuasan pengguna sehingga dinyatakan "Layak" untuk digunakan sebagai website pemasaran kopi. AbstractThis study aims to develop e-catalog as a web-based marketing information system for Sapit coffee and to determine the feasibility of e-catalog marketing of sapit coffee. This type of research uses the method of R&D (Research and Development). The feasibility trial of the learning media was carried out by 2 media experts and 2 material experts, as well as 20 visitors to the web-based sapit coffee marketing e-catalog. Obtained the percentage of eligibility from media experts by 71% by looking at 3 aspects, namely the appearance of the media, functionality, and visual communication so that it is declared "Eligible". The percentage of eligibility from material experts was 93% by looking at 3 aspects namely content design, content, and communication language so that it was declared "Very Eligible". The results of trials on e-catalog visitors totaling 20 people obtained the percentage of eligibility results of 67% by looking at 4 aspects namely usability, information quality, interaction quality, and user satisfaction so that it was declared "Eligible" to be used as a coffee marketing website.

RapidMiner is an application that is used to analyze data quantities and qualitatively to obtain information and knowledge as expected. This software is implemented to process data using several methods or algorithms in Data Minig learning. However, when using this software, users sometimes cannot distinguish between various methods or algorithms in Data Mining. Therefore, it is necessary to evaluate to optimize the use of this software in data mining learning. This study focuses on RapidMiner evaluation of data mining learning using the Persiva model. This model consists of aspects of satisfaction, behavior, impact, and effectiveness. The data collection technique was in the form of a questionnaire with 48 subjects. Data analysis used is descriptive statistics to determine satisfaction, behavior and effects. Meanwhile, Think-Aloud Retrospective technique is used to determine the effectiveness of RapidMiner. Our findings show that users are satisfied with the results of respondents on average agreeing (80%), in the aspect of behavior and impact, the percentage results are above 80%, and the use of this application has been effective with a completion rate above 90%. So it can be concluded that by using this application in data mining learning users can easily complete tasks, and be motivated, and add insights and knowledge in relevant disciplines.

This Community Service program aims to socialize the Zero Waste (ZW) environmental program and to train the community to manage waste (used goods) into goods that can be recycled using an Android-based application. The methods used are lectured and demonstrations (hands-on training). For education on the Zero Waste environmental program through the Zero Waste application, training through demonstrations or direct training (practice). The location for implementing this community service is in Lengkok Lendang hamlet, Tembeng Putik village, East Lombok regency, Nusa Tenggara Barat (NTB) province. So far, at Tembeng Putik, there has never been any training on Waste Management and the Zero Waste environment program, so that public knowledge and awareness about environmental health are still low. The results obtained are the formation of this knowledge about the Zero Waste environment's importance, and the community can make or manage waste into more valuable finished goods

Computational thinking ability need to be trained from an early age through the mathematics ability approach at the primary schools level. This study aims to analyze the effect of the analysis of mathematic ability to computational thinking abilities in primary schools age in sdn 2 sekarteja with 2 measurement variables including: computational thinking ability and math ability. This type of research is quantitative using descriptive methods. The population of this study was class V SDN 2 Sekarteja with a total of 30 students and the entire population becomes the sample, the type of research sample is saturated sample. Data collection techniques in this study used tests and documentation. The technique used to analyze the data was descriptive statistics. The results of this study indicated that, with n = 30 and a significant level of 5%, r table = 0.361, while the result rcount = 0.304. The results obtained were rcount ≤ rtabel, then Ha was rejected and Ho was accepted and the direction of the correlation was negative. It can be concluded that there was no significant relationship between the computational thinking abilities of elementary school age children in terms of mathematics abilities at SDN 2 Sekarteja
