Abstract

Learning media plays an essential role in conveying material to students. Learning media can be divided into media that Teacher directly use in learning and media made by Teacher that later adapted to the abilities and needs of students. Engineering mechanics is one of the primary subjects that civil engineering students must master at. The engineering mechanics course discusses the analysis of the balance of a structure. Students can use mobile application-based teaching materials as online learning media amid the COVID-19 pandemic. Engineering mechanics book, we called EMB, can be used by students to study independently at home during learning online but still in the monitoring/monitoring of Teacher (lecturers). The research and development use ADDIE design. The stage includes 1) Analysis, 2) Design, 3) Develop, 4) Implementation, and 5) Evaluation. EMB product had been tested the validity and implementation during the learning process. EMB got 3.32 valid results for the product. EMB can also train students in digital literacy. Students' digital literacy is in the quite proficient category. This condition is not regardless of the influence of student habits in using technology which is more often used for online communication and entertainment. The frequency of using digital technology for entertainment purposes is higher compared to use for academic purposes.

Abstract

School located in a remote areas has a complex educational problems such as limited teachers, inadequate building conditions, difficult road access and even lack of textbooks. This service aims to help SD N 1 Tumbang Kuling Central Borneo in organizing more varied teaching and learning activities using several learning methods. The Community Service Team introduced guessing method, team games tournament, and singing to students to motivate them in learning despite their limitations. The students can follow the given learning process well and feel happy to be able to learn through the existing methods. This kind of service activity can be an inspiration for the community to assist the government in overcoming the problem of education disparities in schools in a remote areas.

Abstract

The global shortage of freshwater and energy issues require the advancement of sustainable desalination technologies. This work introduces a novel structured fabric combined with an airflow channel for enhanced solar steam generation (SSG) efficiency. The instrument employs a synergistic composite of carbon fiber, serving as a wide-band photothermal absorber, and Tencel, which facilitates rapid capillary water movement due to its hydrophilic cellulose structure. Engineered airflow channels were incorporated into the evaporator design to surmount the thermodynamic limitations of stagnant vapor boundary layers. The findings indicate that a 5 mm channel width offers the ideal equilibrium between vapor diffusion and active photothermal surface area, resulting in a peak mass loss of approximately 1.75 kg/m² under 1 sun illumination. This layout markedly surpassed 2 mm, 10 mm, and non-channeled designs in both photothermal and convection-driven circumstances. This study presents a scalable and efficient approach to improving solar desalination by structural micro-environment alteration.

Abstract

Impulse and momentum mobile app can be another alternative to overcome the problem of using printed teaching materials. Impulse and momentum mobile app present concepts accompanied by examples in everyday life in images, animations, and videos. It can reduce students' difficulties in connecting concepts or materials with phenomena. The difficulties experienced by these students can have an impact negative on students' understanding of physics concepts. The impulse and momentum mobile app shows valid results with an average value of 3.32. Comments and suggestions from the validator are considered as revision material so that impulse and momentum multimedia teaching materials in mobile applications are better, more attractive, worthy of being tested for effectiveness. The mobile app needs to be revised based on comments and suggestions given by physics lecturers and teachers. The improvement of students' understanding of physics concepts is shown by testing the effectiveness of multimedia teaching materials in the experimental class and class control. In the analysis of the different tests with t-test, which involved 70 student respondents, the value of t count is 19.587 with t table of 1.99. P-value is p = 0.000, where the P-value is smaller than 0.05. It can be concluded that there is a significant difference in post-test value data on the ability to understand concepts between the experimental class and the control class. These results indicate that impulse and momentum mobile app effectively improves the ability to understand concepts of student physics.
