Kombucha tea is a drink produced through a fermentation process of a mixture of tea and sugar using kombucha culture or also called SCOOBY ( Symbiotic Culture of Bacteria and Yeast) . The basic ingredients for making kombucha tea are granulated sugar solution and tea bags, in this study it was varied using fruit skin. Vitamin C is known as an important antioxidant found in many fruits, including in rujak fruit skin which is often considered waste. The purpose of this study was to determine the levels of vitamin C in kombucha tea fermented from fruit skin waste. This study used qualitative and quantitative methods. The qualitative method uses the Benedict test and the quantitative method uses the calculation of the percentage of vitamin C content using the iodimetric titration method. The results of the qualitative analysis of the Benedict test were positive for vitamin C with a change in the color of the sample solution to green-yellowish and the analysis of the percentage of vitamin C content obtained a result of 2.3124% or equal to 0.23124 mg / 10 mL of sample solution. The vitamin C content of kombucha tea can vary depending on the base ingredients used, fermentation time, and storage temperature.

Electrical energy is a vital element in daily life, supporting nearly all equipment used. One of the main components in the electrical distribution system is the 20 kV cubicle. This cubicle plays an essential role in controlling power flow, protecting the system from faults, measuring electrical parameters, and enabling remote monitoring and control. Additionally, the cubicle functions to maintain the stability, reliability, and efficiency of power flow to load centers. However, various technical issues, such as short-circuit faults, protection system failures, and corona phenomena caused by high humidity, often threaten its performance. This study aims to evaluate and optimize the design and operation of 20 kV cubicles in electrical distribution systems. The research focuses on analyzing technical factors that affect energy efficiency and system reliability, as well as identifying challenges in implementation, such as installation and maintenance issues. The research methods include literature reviews, interviews, and field observations. The results indicate that modular designs, high-quality insulating materials, and modern technologies such as Intelligent Electronic Devices (IEDs) and Supervisory Control and Data Acquisition (SCADA) enhance system efficiency and reliability. It is recommended that cubicle designs be adapted to the load capacity and routine maintenance be performed to maintain efficiency and extend equipment lifespan.
