Teaching and learning have shifted from synchronous meetings in the classroom and laboratory to virtual synchronous and asynchronous meetings. Teaching and learning can take place anytime and anywhere. The availability of ICT infrastructure is one of the supporting factors for teaching and learning in today's Education 4.0. This article describes the availability of ICT facilities to support blended learning. Accidental sampling was conducted on 56 lecturers of the Faculty of engineering, Universitas Negeri Yogyakarta (UNY), who participated in a webinar and filled out polls. The polls revealed that nearly 72% of respondents had subscribed to Internet Service Providers and cellular data packages. Total respondents who own laptops or PCs with Intel Core i3 / AMD Ryzen 3 processor specifications were only 23%, yet a mere 4% still own lower processors specifications. Cloud-based software provided by UNY, such as Microsoft 365, was only used by 46% of respondents. The availability of facilities to support virtual synchronous meetings included headset 96%, Zoom educational license 86%, and interactive application 18%. In contrast, facilities to support asynchronous meetings were owned only by less than 60% of respondents, including condenser or clip-on microphone types, graphic pads, video editing software, screen recording software, and project management software. Facilities to support collaborative asynchronous activities such as Google Workspace were applied by 66% of respondents. The availability of ICT facilities supporting teaching and learning is an indicator of readiness for Education 4.0, and this study shows it needs to be improved.

Indonesia has a high tendency of having landslides. Bogor is one of regency which is very prone to landslide disaster due to high rainfall. Landslides are a very dangerous threat to public safety. The preparedness can build disaster resilient communities that can support the national resilience. Sociodemographic characteristic and disaster experience are determining factors for the success of preparedness. The purpose of this research is to develop a model of the influence of sociodemographic characteristics and disaster experience toward household preparedness for facing landslide. This research is done in Cibadak Village, Sukamakmur Bogor. This research uses a quantitative approach with 100 sample of households. Multiple linear regression technique is used for analyzing the model. The results of the research showed that household preparedness is significantly influenced by sociodemographic characteristics which is education (p = 0.000), meanwhile age, income and the number of family member don't significantly influence. Beside that the household preparedness is also greatly influenced by disaster experience too (p = 0.000). Education influence on household preparedness for facing landslide as much as 38.81% and the disaster experience is 52.85%. © Published under licence by IOP Publishing Ltd.

With the rapid growth of the textile, leather, cosmetics, and pharmaceutical industries, concerns about pollutants in these sectors, especially dye pollutants, are increasing. This research characterizes bacterial nanocellulose acetate membranes made from Sargassum extract reinforced with copper oxide nanoparticles and tests their antibacterial properties and dye removal in water. Sargassum sp. extract was fermented using Acetobacter xylinum for 10 days, producing bacterial nanocellulose, which was then esterified to create bacterial nanocellulose acetate. Copper oxide nanoparticles were added to the bacterial nanocellulose acetate solution in varying concentrations, cast, and oven-dried. The membrane was analyzed using Fourier-transform infrared spectroscopy, X-ray diffraction, scanning electron microscope, antibacterial activity, and dye removal. Results showed uniform copper oxide nanoparticles distribution on the membrane surface. Structure analysis revealed diffraction peaks at 35.44° and 38.57°, indicating a reduced crystalline index but improved membrane effectiveness. Antibacterial tests showed a zone of inhibition against bacterial growth, increasing with higher copper oxide nanoparticle content. The addition of copper oxide nanoparticles also influenced the dye removal capacity for Metanil Yellow, Congo Red, Eosin Yellow, Methylene Blue, and Malachite Green. The kinetic analysis showed that the adsorption process follows a pseudo-first-order model, with higher correlation coefficients (R2) compared to the pseudo-second-order model. © 2024 The Author(s)

Gamification is the process of incorporating game design aspects into non-gaming products or services to enhance usage and provide more long-term effects. The implementation of gamification in diverse practical focus areas necessitates the application and adaptation of the gamification theoretical idea to technological breakthroughs and their application. The goal of this study is to examine the determinants of gamification in the marketplace using gamified learning theory. This research takes a quantitative approach, utilizing SEM-PLS modeling and the SmartPLS 4.0 analytic tool. Participants from Generation Z were employed for this study. This group is recognized for its tendency to become readily bored and to move around while utilizing a product. According to the findings of this study, varying the intensity of recommendations to other people can demonstrate that the output does not only stop at the outcomes of playing, such as the acquisition of coins or other rewards, but also extends to the act of recommending to others. This is consistent with the game's features, which include the ability to invite friends to help finish objectives. This study has theoretical significance for enhancing differentiated learning theory. In practice, the findings of this study highlight the importance of consistently designing instructional features and content to keep students' attention. The research's flaws stem from the usage of limited game elements and the participants' background profile, which was ignored in favor of ignoring their game experience.

This study evaluates bacterial cellulose (BC) membranes reinforced with zinc oxide nanoparticles (ZnO-NP) derived from pineapple biowaste. While BC membranes are widely studied, their use in aquaculture and ZnO reinforcement remains underexplored. Membranes were synthesized with 0.25–1.0 wt% ZnO-NP and characterized by SEM, XRD, FTIR, tensile strength, antibacterial activity, filtration efficacy, and analysis using one-way ANOVA. Results showed ZnO-NP enhanced membrane crystallinity and tensile strength, with 0.25 wt% being optimal. The membranes exhibited improved antibacterial activity, reducing bacterial content by 90.6 % and contaminants by 57 %, enhancing water quality for aquaculture and supporting sustainability and the long-term viability of aquaculture. © 2025

A manipulator robot is a robot that has a mechanical system consisting of an arrangement of arms and joints that can produce controlled movements. A robotic arm usually consists of several joints including the base, shoulder, elbow, roll, gripper, and pitch of the gripper. Robot movement is generated from mathematical calculations performed in the controller. The motion of the manipulator robot follows a motion trajectory. The motion trajectory is made based on a collection of stop points and effectors. This study aims to create a robot motion trajectory design system using Lagrange interpolation. Lagrange interpolation is engineered to be embedded in precise microcontroller control systems. In this study, an Arduino Uno R3-based microcontroller was used as a data acquisition module. Prediction of the robotic arm's trajectory has been successfully made using Lagrange interpolation. The rise time is 15 seconds, the delay time is 12 seconds, the steady-state time and the peak time are 21 seconds. While the second experiment increased 9 seconds, 7 seconds of delay, steady-state time, and 13 seconds of peak time. Then for the third experiment, the rise time is 17 seconds, the delay time is 14 seconds, the steady-state time and the peak time are 22 seconds, the overshoot value and the steady-state error value is 0% where the output value produced is by the input value.

The Raman peak position and linewidth provide insight into phonon anharmonicity and electron-phonon interactions in materials. For monolayer graphene, prior first-principles calculations have yielded decreasing linewidth with increasing temperature, which is opposite to measurement results. Here, we explicitly consider four-phonon anharmonicity, phonon renormalization, and electron-phonon coupling, and find all to be important to successfully explain both the G peak frequency shift and linewidths in our suspended graphene sample over a wide temperature range. Four-phonon scattering contributes a prominent linewidth that increases with temperature, while temperature dependence from electron-phonon interactions is found to be reversed above a doping threshold (ℏωG/2, with ωG being the frequency of the G phonon).
