Abstract

Flipped classroom (FC) have advantages compared with traditional lectures. One of them is the occurrence of active learning.  This study aims to assess the flipped classroom learning method's effectiveness, feasibility and acceptability. Research method with mixed method. Quantitative method with pre-test and post-test control group design. One with traditional lecture (TL) and another with the flipped classroom method. Effectiveness was assessed by pre-test and post-test. The post test was carried out on day 0, 3, 7 and 14. FGD assessed the feasibility and acceptability of FC. TL are in pregnancy physiology courses, while FC are in labor physiology courses. There were differences in pretest scores in the FC group compared to TL, 4.89 (± 0.85) vs 4.29 (±1.01) (p=0.000), respectively. There were differences in posttest scores d-0, d-3, d-7, d-14 between the FC group and TL group, 7.89 (± 0.85) vs 7.29 (±1.01) (p = 0.000); 6.82 (± 0.78) vs 6.14 (±0.81) (p= 0.000); 5.85 (± 0.80) vs 5.20 (±0.88) (p= 0.000); 5.81 (± 0.77) vs 4.78 (±0.82) (p= 0.000), respectively. FC are difficult, burdened students, stimulate more active learning, are not suitable for certain learning, and provide an overview of real situations.

Abstract

Zooplankton in the food chain acts as the primary consumer which connects phytoplankton as producers with organisms that have higher nutritional levels, for example nekton and benthos. This research aimed to identify zooplankton diversity and abundance in Lake Sunter. This research used a purposive sampling method to take the samples, to determine station points based on the environmental conditions of the lake. The results obtained were the identification of species from the genus Candacia, Nauplius, Eudiaptomus, Tintinnopsis, Polyarthra, Brachionus, Trichocerca, Philodina, dan Polydora. The diversity index of station 1 was categorized as medium (1.32), station 2 was in the low category (0.64), and station 3 was in the medium category (1.47). The abundance value at station 1 was 26,000 Ind/L, station 2 had an abundance value of 9,302 Ind/L, and station 3 had an abundance value of 32,500 Ind/L. In conclusion, the results of research at Lake Sunter found 9 genera of zooplankton. The diversity index of Lake Sunter was in the low to medium category, which indicates that the area has high ecological pressure and the species diversity index is low. The zooplankton abundance index value was categorized as high because each station had an abundance value above 500 Ind/ L.

Abstract

The Commuter Line is a train service that serves short routes within or between cities, mainly for daily commuters in urban areas. Launched on February 10, 2021 to replace KRD Prameks, KRL Jogja-Solo aims to improve the efficiency of intercity travel. Passenger numbers for KRL Jogja-Solo continue to increase, based on PT KAI Commuter Line's latest data, with passenger numbers per month in 2023 showing a significant increase. For example, in August there were 512,547 passengers, while in December it increased to 709,634 passengers. This increase creates pressure on the existing carrying capacity. This research aims to assess the challenges faced by KRL Jogja-Solo in accommodating the increasing number of passengers and find solutions to meet the growing demand. This research focuses on improving the operational efficiency of KRL Jogja-Solo through schedule improvements, assessing passenger volume, cross capacity, and passenger projections for the period 2024-2033. The Scott method is used for cross capacity analysis and the geometric growth formula for passenger projections, with optimal solutions based on optimistic, moderate, and pessimistic scenarios. Results show that the addition of four afternoon trips and skip-stop scheme is the best solution in the optimistic scenario, skip-stop scheme without additional trips in the moderate scenario, and improvement of the existing schedule in the pessimistic scenario. This research emphasizes the importance of long-term planning and regular evaluation to ensure the smoothness and convenience of the Jogja-Solo KRL service.

Abstract

This study aims to develop learning media by utilizing the TikTok application with the PBLA model on the topic of measurement and to determine the enhancement of participants' argumentation skills. This study is a Research and Development (R&D) study employing the ADDIE development procedure (Analyze, Design, Development, Implementation, and Evaluation). The research subjects were 36 students from class X-E of MAN Purworejo in the academic year 2023/2024. The research instruments used were validation sheets, participant response questionnaires, observation sheets, pretest-posttest questions, and learning implementation sheets. The data analysis results show that the physics instructional video media utilizing the TikTok application with the PBLA model meets the "valid" criteria, with material expert validation scoring 3.45, equivalent to 86.30%, categorized as "good," and media expert validation scoring 3.58, equivalent to 89.58%, categorized as "very good." The developed physics instructional video media using the TikTok application with the PBLA model received a score of 85.5% with the predicate "very good" from participant response testing. Meanwhile, the observation data on learning implementation achieved a Percentage Agreement (PA) score of 99% with the predicate "reliable," meeting the "practical" criteria. Utilizing the TikTok application with the PBLA model is effective according to trial results using a paired sample t-test, which produced a calculated t-value of 0.000 < 0.05, indicating an improvement in argumentation skills after using physics learning media with the TikTok application. Thus, the developed physics learning media is considered "effective" for improving students' argumentation skills based on pretest and posttest scores with a normalized gain of 0.71, which falls into the "high" category.
