Sumber air bersih yang berasal dari sungai sudah tercemar dan tidak bisa digunakan untuk kebutuhan sehari - hari. Salah satu penyebab pencemaran air sungai adalah limbah kamar mandi. Sifat air limbah kamar mandi yang basa dan mengandung banyak deterjen mengakibatkan air tersebut susah diurai oleh mikroorganisme yang ada dalam air, agar air limbah tersebut dapat digunakan, maka perlu adanya proses daur ulang. Penelitian dilakukan menggunakan teknologi plasma untuk mengolah air limbah. Plasma dibangkitkan dengan menggunakan memodifikasi transformator flyback berfrekuensi 7 KHz, 8 KHz dan 10 KHz. Tegangan yang dihasilkan berupa tegangan tinggi (High Voltage) antara 5 ? 24 KV. Variabel yang diteliti dari air limbah kamar mandi adalah pH dan TDS (Total Dissolve Solid). Proses daur ulang dimulai dengan dipaparkannya plasma pada permukaan air selama 20 menit dan dijaga pada suhu konstan. Hasil penelitian menunjukkan terjadi penurunan pH air dari 10,0 menjadi 8,1 dengan menggunakan teknologi plasma (electron discharge). Sedangkan untuk pengukuran TDS mengalami kenaikan dari nilai 135 ppm menjadi 210 ppm.

Clean water sources from rivers are polluted and cannot be used for daily needs. One of the causes of river water pollution is bathroom waste. The nature of bathroom waste water which is alkaline and contains a lot of detergent causes the water to be hard to decompose by microorganisms present in the water. so that the wastewater can be used, it is necessary to have a recycling process. The study was conducted using plasma technology to treat wastewater. Plasma is generated by modifying flyback transformers with a frequency 7 kHz, 8 KHz and 10 KHz. The resulting voltage is in the form of high voltage (High Voltage) between 5-24 KV. The variabels studied from bathroom wastewater were pH and TDS. The recycling process begins with the exposure of plasma to the water surface for 20 minutes and maintained at a constant temperature. The results showed a decrease in water pH from 10.0 to 8.1 using plasma (electron discharge) technology. As for the measurement of TDS, it has increased from 135 ppm to 210 ppm.

Comma 2.0 is an English learning application for early childhood that is specifically created for TK Roudlotul Muttaqin Mojokerto. . The purpose of this research was to process user feedback regarding the comparison of the development of Comma 2.0 with the previous version by using the Quality Function Deployment method in order to provide more optimal development in accordance with the users' expectations. One of the methods proven to be effective in language learning was Total Physical Response (TPR), which emphasized learning English by using three important aspects: commands, speaking, and actions. The research employed an experimental design with 15 children aged 4–6 years as participants. Data were collected through structured observations and user feedback assisted by teachers and parents, and analyzed using the Quality Function Deployment (QFD). The analysis focused on five attributes: material comprehension, application usability, attractiveness of animated characters, clarity of sound and visuals, and ease of imitating animations and sounds. From the results of the research, it could be concluded that the Comma 2.0 application was easy to use, contained easy-to-understand materials, and featured attractive animated characters with clear images and sounds that were easy to imitate by the application users.

This study investigates the effectiveness of the Ocean application in enhancing listening skills among maritime students, a crucial competency in the maritime industry where clear and accurate communication can significantly impact safety and efficiency. The primary purpose of this research is to evaluate how the integration of auditory and visual stimuli within the Ocean application can improve students' ability to comprehend and retain maritime communication protocols. A mixed-method approach was employed in this study to provide a comprehensive analysis of the application's impact. The quantitative aspect involved pre- and post-assessment tests administered to a sample group of maritime students, measuring their listening skills before and after using the Ocean application. The qualitative aspect included interviews and surveys to gather user feedback on their experiences with the application, focusing on its usability, engagement, and perceived learning outcomes. The results of the study demonstrated a marked improvement in the listening skills of students who utilized the Ocean application. Quantitative data showed a statistically significant increase in test scores, indicating enhanced comprehension and retention of the material. Additionally, qualitative feedback from students highlighted the application's interactive features, such as synchronized audio-visual content, as particularly beneficial for maintaining engagement and reinforcing learning. Students reported that the application made complex maritime communication scenarios easier to understand and practice. These findings suggest that the Ocean application is an effective tool for enhancing listening skills in a maritime education context. The study concludes by recommending the broader adoption of such technology-driven learning tools in maritime training programs, emphasizing their potential to improve essential communication skills and overall safety in the industry.
