Disposable diapers are non-biodegradable waste that can pollute the environment. Disposable diapers contain super absorbent polymer (SAP) which has an absorption capacity of up to 1,000 times. SAP can be combined with activated carbon as a coating agent in urea slow-release fertilizer (SRF) production. This research aims to analyze the effect of urea SRF formulation (FA, FB, FC, and FD), with the combination of SAP and activated carbon, on the characteristics and nitrogen release behavior. SRF was characterized by Scanning Electron Microscope (SEM), Fourier Transform Infra-Red (FTIR), and Water Retention (WR) testing to determine the morphological structure, functional groups, and the ability of the sample to retain water during observation. The percentage of nitrogen release from SRF was calculated using the Kjeldahl method. The results of SEM characterization show that the thickness of the layer formed is about 63.5 µm. Different sample formulations affect the intensity of the functional groups produced. From all formulations, FD showed the highest WR and the lowest nitrogen release percentage with values of 80.2% and 20.4%, respectively. In general, it can be concluded that the combination of SAP from disposable diapers and activated carbon can be used as a coating agent in SRF production.

The era of digitalization has a significant impact on various aspects of life, including education. However, the existence of traditional games is increasingly eliminated due to technological developments. This study examines the implementation of the traditional game of ball ball as an interactive learning medium of the earth's gravitational force for elementary / middle school students. Using  the Systematic Literature Review (SLR) method, this study identifies the benefits of the game of ball ball in improving students' understanding, motivation, and learning outcomes through a fun and interactive approach. The results of the study show that the ball game is able to integrate the concept of the earth's gravitational force in a simple but effective way. The game also facilitates the development of students' cognitive, psychomotor, affective, social, and spiritual aspects. The use of the game of ball in learning not only increases students' interest but also creates an inclusive and collaborative learning environment. The conclusion of this study confirms that the traditional game of bekel ball is an innovative and relevant learning medium in teaching physics concepts, especially the earth's gravitational force. The practical implications can be used as a guideline for educators to develop learning strategies based on local wisdom that support in-depth conceptual understanding. Further research is recommended to explore the potential of other traditional games in the learning of complex science concepts.

One of the key processes in the production of APAR cylinders is the welding of cylindrical plates, which is carried out using a Longitudinal Welding Cylinder machine and the CO₂ welding method. However, in practice, operators face several challenges, mainly due to the number of process steps that do not significantly contribute to the quantity or quality of the output, resulting in reduced productivity. This study aims to improve the productivity of the welding process through a series of improvements. The methods used include data analysis and root cause identification through the Overall Equipment Effectiveness (OEE) approach and Lean Six Sigma using the DMAIC stages (Define, Measure, Analyze, Improve, Control). Based on the Define stage, the initial OEE value was 67.49%, which is still far below the world-class standard of 85%. In the Measure stage, Pareto analysis revealed that the largest downtime (2,097 minutes or 40%) was caused by cycle time issues. Further analysis showed that activities such as material setup, additional plate placement, and additional plate cutting (totaling 85 seconds) could still be optimized. During the Improve stage, modifications were made, such as eliminating the additional plate cutting process and adding a stopper to ensure accurate welding alignment. These improvements successfully reduced the cycle time from 180 seconds to 120 seconds, thereby decreasing downtime and increasing the OEE value to 76.12%.

The utilization of OP-AMP as controllers for temperature sensors plays a crucial role in both the manufacturing and automation sectors. Nevertheless, traditional learning approaches often fail to engage students, leading to diminished interest and lower academic performance. To address this issue, an interactive learning media based on Android technology is being developed, aimed at enhancing current teaching methods and improving students' understanding of OP-AMP applications in temperature sensor control. The objectives of this study are threefold: (1) to analyze the viability of the developed learning media, (2) to evaluate the impact on learning outcomes, and (3) to compare the learning improvements between this new media and traditional teaching methods. The research follows the ADDIE model, with data collection carried out via pre-tests and post-tests. Media feasibility was evaluated using CVR and CVI tests, while the cognitive test's validity was measured through Aiken's V and ICC. Data analysis employed a two-tailed t-test and N-Gain calculation. The study involved 72 eleventh-grade students from the Industrial Electronics Engineering program at SMK NU Ungaran. Results indicated that the Android-based interactive learning tool was highly effective, with a CVR above 0.75, an Aiken's V score of 0.90, and an ICC value of 0.797. Moreover, this learning media significantly enhanced students' academic performance, with a t-value of 30.234 and a p-value of 0.000. The experimental group saw a 74.4% improvement in learning outcomes, compared to 67.4% in the control group, demonstrating the media’s effectiveness in teaching OP-AMP applications.
