ECE) English teachers, focusing on its relationship with leadership perspectives and practices within the context of their listening classes. The study employed a mixed-methods research design and used a questionnaire as its instrument. questionnaire, in which its high reliability was guaranteed by the use of (Cronbach's Alpha = 0.930) and a validity test on its instruments, which confirmed that all items were valid for hypothesis testing. A group of 50 ECE English teachers offered their participation, and data was collected via a questionnaire. Descriptive analysis revealed positive feedback from respondents, concluding the significance of fostering listening skills in educational settings. The appropriateness of the data for regression analysis was ensured by employing classic assumption tests, including normality, multicollinearity, heteroscedasticity, and autocorrelation. Multiple linear regression analysis revealed a significant positive influence of both Teacher Leadership Perspective (β = 0.496) and Teacher Leadership Practice (β = 0.433) on Teacher Leadership Identity, with the model explaining 74.9% of the variance in the dependent variable. Findings stated the importance of understanding the interconnections among these constructs to enhance teacher leadership in educational contexts. It is recommended that educators facilitate programs focused on leadership and listening skills and establish professional learning communities to improve listening effectively. This study’s limitation is its reliance primarily on quantitative and qualitative data. Future research may benefit from a cross-method approach to avoid reliance on a single form of data.

Magnetohydrodynamics is a method for generating electricity by utilizing the interaction between a magnetic field and an electrolyte fluid. MHD components: salt water electrolyte, Neodymium N52 magnet, and Cu-Zn electrode. The MHD used is a coarse salt water electrolyte. The purpose of the MHD model is as an innovative technological breakthrough that is used to support increasing the efficiency of the power generation system. The lowest efficiency is shown in the second data with variations in salt content of the 5 grams/liter experiment without MHD support, which is 0.08%. The highest efficiency is shown in the twentieth data with variations in salt content of the 95 gram/liter experiment supported by MHD, which is 0.59%. The maximum efficiency increase that can be achieved is 0.37% with variations in salt content of 60 grams/liter.

””Overcurrent Relay is one of the protection system tools in the electricity network. Overcurrent Relay works based on the increase in fault current that exceeds a certain safety value and a certain period of time. The type of relay that will be used in this test is the IDMT NX203A Overcurrent Relay. The purpose of this test is to get a good practicum module and to prove the inverted time relay characteristic curve according to British Standard BS142. In the test, the tool to be assembled is tested for its work function so that in data collection errors can be avoided while the relay on the module will be given a current setting of 2A; 3A; and 4A with TMS0.05; 0.5; and 1.0 which will be connected to a digital timer so that if the fault current exceeds the setting current, the relay will automatically give a signal and the digital timer will show the time when the current is cut off. The final result is a practicum module where each tool functions under normal working conditions and a graph of time against relay current for setting current 2A, fastest time 0.498s at 9A fault current and 0.05 TMS, longest time 12.991s at 4A TM fault current. . 1.0. Current setting of 3A for the fastest time is 0.572s at fault current of 9A and TM 0.05, for the longest time is 35.854s at fault current of 4A and TM 1.0. Current setting of 4A for the fastest time is 0.708s at fault current of 9A and TM 0.05, for the longest time is 55.979s at fault current of 5A and TM 1.0.

The important matter about biogas as an alternative energy source was the presence of hydrogen sulfide (H2S) which is very corrosive. The biogas desulfurization process was absolutely necessary to reduce the risk of damage to the equipment. For small-scale applications, the selection of the type of adsorbent became important to reduce additional costs. One alternative material that can be used was iron gram waste. The aim of this study was to investigate the use of iron gram waste resulting from the machining practicum process at the Department of Mechanical Engineering, Politeknik Negeri Semarang as an alternative material for making adsorbents. Iron gram waste was processed into Iron (III) Oxide (Fe2O3) and Iron (III) Hydroxide (Fe(OH)3), formed into billets with an average billet mass of 250 gr. The performance test of the adsorbent in the biogas desulfurization process was carried out under conditions of variation in the flow rate of biogas feed 1, 2, and 3 liters per minute, and the volume of biogas purified in one process was 50 liters. As a result, the most optimum performance was obtained in the test with a feed biogas flow rate of 1 liter/minute, with a percentage reduction in H2S levels contained in the biogas by an average of 82,56%.

Energy audit is very necessary to calculate the level of energy consumption of a building or buildings. The research includes the amount of energy consumption based on the initial energy audit and detailed energy audit as well as saving opportunities based on conditions in the field. Based on the initial energy audit, the value of the Energy Consumption Intensity (IKE) is 0.699 kWH/m2month, while in the detailed audit the IKE value is 0.935 kWH/m2month. Based on the results of a detailed energy audit, the lighting measurement of 325 lux still meets the requirements for a classroom with a standard between 250 lux to 500 lux.

The limitations of deaf students in hearing significantly impact the minimal reception of information from their environment. This encourages deaf students to utilize their visual senses more by reading. This study aims to create a mobile learning product based on a multisensory approach to learning to read descriptive texts to improve the descriptive text reading skills of deaf students. This study uses a research and development method by adopting the Four-D model as a procedure for developing the product. The subjects in this study were deaf students, 2 media experts, 2 material and language experts, and an Indonesian subject teacher. This study's data were from observations, interviews, and questionnaires. The data analysis technique used a qualitative descriptive approach and a quantitative descriptive approach. This study has produced mobile learning based on a multisensory approach to learning to read descriptive texts that is feasible and practical for deaf students. In addition, this mobile learning is equipped with visual, tactile, and interactivity elements that support the multisensory principle that can be implemented in learning to read descriptive texts. This study concludes that mobile learning is very effective in helping deaf students understand the material and overcome the limitations of learning resources. This research implies that mobile learning can help overcome the limitations of learning resources for deaf students and is very effective in supporting the improvement of reading skills.
