Abstract

Abstract: The purpose of this study was to determine the effect of the Problem Based Learning (PBL) model on the science learning outcomes of Class VIII students of SMP Negeri 10 Sungai Penuh City. This type of research is quasi-experimental, using a Randomized Control-Group Posttest Only Design. The population in this study were all Class VIII students for the 2021/2022 academic year. The sample in this study was selected using a random sampling technique. The results showed that the science learning outcomes of experimental class students using the PBL model obtained a higher average score than the control class using the direct learning model, with an average score of 79.94 for the experimental group and 70.82 for the control group. In conclusion, the PBL learning model influences the science learning outcomes of Class VIII students of SMP Negeri 10 Sungai Penuh. Keywords: Learning Outcomes, PBL, Students

Abstract

Abstract: This research aims to produce a product in the form of Microlearning that students of class VIII SMP can use on vibration, wave, and sound material in everyday life. Research conducted in developing Microlearning on the pulse, ripple, and suitable material for class VIII SMP students, which has been carried out in sequential steps in obtaining product feasibility, was carried out by design experts of 83%, material experts of 82.3%, and media experts of 82.8% which means the product is suitable for use and can be followed up in trials on students in learning. The instrument used for product trials in the field obtained validity test results using a product-moment correlation of 0.266 (the correlation coefficient value was more significant than the Product Moment r-table matter). It said that the instrument in this study was valid or could measure the variables studied. The results of the reliability test were 0.920 (this value was more significant than the r-table value of 0.6), meaning that the results of the respondents' answers were reliable. In other words that if the same research were carried out at different times, the respondents would give the same answer. In conclusion, learning media products for developing microlearning video content on vibrations, waves, and sound materials for students of class VIII SMP in science learning can be significantly feasible to use in the learning process. The conclusions are obtained from the results obtained in the description of the data shown, which indicates a positive response when the trial is carried out. Furthermore, this product will be disseminated primarily to the local school environment and other schools to provide insight into this product. Microlearning is designing learning media (short videos, infographics, pictures, articles) into small segments and focusing on the expected learning objectives. Can accommodate the limitations of media and time variations in the teaching and learning process of e-learning vibration, wave, and sound material in everyday life for students of class VIII science subjects.

Abstract

Abstract: This study aims to determine the design of an LPG gas leak detection system using Internet-based Nodemcu ESP866. LPG gas cylinders are an essential kitchen fuel for most people. In preparing the research, the authors first collected data by conducting a literature study to find out the schematic circuit, component datasheet, and how the components work. Based on statistical data from the fire department from January 2010 to August 24, 2010, there were 46 fire incidents in the DKI Jakarta area, with an estimated material loss of Rp. and many materials. With the results, we get from our tool. Namely, the Buzzer as an alarm, the LED as an indicator, and the DC Fan can be On when the sensor detects a leak in the gas cylinder. In conclusion, the tool can be integrated with a smartphone using Wifi. In testing the device, the measurement range is 5-30 meters. At a distance of 5 meters, it produces 4.76, and at a distance of 10 meters, the time difference is around 2 seconds slower for smartphones to receive notifications. At a distance of 20 meters, it produces 7.66 seconds; at a distance of 30 meters, the time difference is 2.5 seconds slower for smartphones to receive notifications.

Abstract

Abstract: This study aims to determine how the level of communication skills is seen from the group of students' initial understanding and the level of students' final understanding. Is there a difference, and how much is the increase in students' communication results after applying the Think Talk Write model using PowerPoint media? This type of quantitative research with quasi-experiments utilizing a control group design. The population in the study was class VIII A as the control class and class VIII B as the experimental class, each of which consisted of 20 students. Data collection was obtained using the method of documentation, testing, and communication observation. The results showed that the application of the TTW Learning Model (Think Talk Write) using PowerPoint media to improve students' communication skills for the initial level of student communication results was included in the low category, with an average of 48.70 for the control class and 48.70 for the experimental type. The story of student communication is obtained from the pre-test scores. The students' final communication results increased after treatment, averaging 72.75 for the control class and 90.30 for the experimental type. The students' last communication level was obtained from the post-test scores. In conclusion, there are differences in improving communication results using the Think Talk Write (TTW) learning model using PowerPoint (PPT) media to improve student communication.

Abstract

Lateness is a common risk factors in construction projects that may result in additional costs and fines according to the project agreement. In order to meet the predetermined specifications and completion schedule, the contractor must carefully plan the project and sequence the work tasks to create a rational schedule. This study focuses on the use of probabilistic scheduling to overcome delayed construction projects, especially in the case of the Pogalan Health Center development project. The process involves data collection, network planning, identification of critical paths, implementation of overtime hours, and Monte Carlo Simulation using @RISK software. The simulation results show that the probability of completion of the Pogalan Health Center construction project within 161 days is 95%-99%, the probability of completion within 154 days is 2.5%-20%, and the optimal duration is 160 days with a probability of 75% based on the random number distribution. highest. However, accelerating the completion of the project will incur additional costs. For example, completing it within 154 days will require an additional fee of Rp. 25.160.080,00.
