Throughout 2020, what was implemented at UM had an impact on the learning of practical subjects. Practical learning that has been carried out in laboratories/workshops must switch to an online system. One of them is the Body Electrical Practicum course, 3 credits/6 JS. Due to the nature of courses that are usually carried out by laboratories to provide effective skill acquisition and hands-on experience, it is often difficult to make these laboratories accessible online. Therefore, the solution offered in this research is to develop virtual lab-based learning content to complement the learning content that has been implemented so far. The purpose of this research is (1) to produce appropriate learning media (2) to test the effectiveness of the developed media. This research method uses research and development of the ADDIE model which consists of analysis, design, development, and implementation. Meanwhile, the data analysis used is in the form of a percentage that describes the size of the feasibility of the virtual lab developed according to experts, and the tow tail test is used to test the effectiveness. Based on the feasibility test from the experts that the developed media is suitable for learning in electrical courses in the Department of Mechanical Engineering, State University of Malang with minor revisions. While the results of the effectiveness test show that the media developed is very effective, as evidenced by an increase in the value of the respondents who are the object of the test. The contribution of this research is to complement the offline practical learning that has been carried out so far, so that it can provide solutions for online practicum models during the pandemic.

Battery cathode material is one of the four determinants of energy storage capacity, which is used as a power source in electronic equipment. laptops, and electric vehicles. Synthesis of the cathode material for LiNiO2 battery with one stage co-precipitation method, and variations in calcination time of 3, 6, 9 and 24 hours with a constant temperature of 7000C. Microstructure observations with SEM showed an uneven and homogeneous surface. The elemental compositions of Li, and Ni were analyzed by EDXS showing that Li and Ni metal decreased with increasing calcination time. The results of the crystal structure test using an X-ray diffractometer showed that with increasing calcination time the crystallite diameter decreased, but the dislocation density increased. The micro-lattice strain increased with increasing calcination time in the planes of the Miller hkl index (102), (104), (210), (108), and (113). The FTIR spectra show that the peak at wavenumber 433 cm-1 is caused by the asymmetric stretching vibration of Li–O in LiO6 and bending vibration of NiO6, namely [(Ni–O–Li)], appearing at 603 cm-1.

This study aims to determine the increase in learning motivation and learning outcomes in technical drawing lessons for class X TKRO 3 SMKN 1 Bulakamba students in the even semester of the 2021/2022 academic year. This research is a classroom action research conducted in two cycles, where each cycle consists of four stages, namely: planning, implementing action, observing, and reflecting. Learning in the first cycle was carried out by blended learning with a flipped classroom, while the learning in the second cycle was carried out by blended learning with a flipped classroom using a contextual teaching and learning approach. Sources of data were obtained from 36 students of class X TKRO 3, learning motivation data was obtained from questionnaires via google form while learning outcomes data were obtained from formative test scores and worksheet scores.

Hydropower on the lowest scale namely propeller pico-hydro, the turbine has a light workload so that allows it to be made from polymer materials with rapid manufacturing 3D printing technology. In the design of the propeller turbine, the most concerned loading is the axial load which results in failure. A failure of designing the dimensions of the propeller turbine with polymer materials causes a fracture in the blades. This study aims to analyze how the effect of blade thickness on the performance of a propeller water turbine. Data collection in this study uses numerical simulation through computational fluid dynamics using SolidWorks Flow Simulation with the blade thickness variable used 1 mm to 3 mm with a fillet size 1.5 mm. Based on the results, the thickness of the blade affects the value of static torque. At a blade thickness of 2 mm, it shows the most optimal torque value compared to a thickness value below or above 2 mm.

A solar thermal converter is an alternative device to optimize the generation of electricity. One implementation of it is Solar Updraft Tower (SUT) which has some advantages such as easy installation, zero-emission, and long-life investment. This paper aims to describe a method to design the process of a SUT power plant which can be used to predict the expected mechanical power output. The application is built using an open-source computation software, GNU Octave, to produce an interactive user interface. In this paper, data is collected experimentally from SUT prototype in laboratory scale. The operational data is processed using the proposed application to analyze the effect of the variation of inlet diameter on mechanical power output. From the result, the power output increases along with the increasing inlet diameter. The highest power output is produced by a SUT diameter of 0.165 m. This study contributes to increasing the development of renewable energy technology of solar thermal power plants.
