Electrical energy is one of the most important energies in everyday life so high-voltage electrical equipment has a vital role in maintaining the reliability of electric power distribution. The corona effect is caused by insulation failure in high-rise equipment which results in disrupted electrical power distribution. The purpose of this research activity is to produce a multi-sensor tool to test the condition of equipment in distribution network booths that have experienced the corona phenomenon. The input data from several sensors used, such as the ozone sensor, will detect ozone gas exposed in the 20kv chamber, detection of ultraviolet light by the UV sensor module, and detection of sound frequency from the hissing of equipment through the microphone sensor experiencing corona will be processed by the Microcontroller and if the value is detected exceeds the reference value that has been set, the output in the form of an LCD will display a corona symptom warning message and instruct the buzzer alarm to sound. The results showed that the prototype of the corona detector was able to identify ozone levels with a maximum value of 21.88 ppb, the largest UV index value of 336, and a maximum hissing frequency of 157 dB in distribution cubicles that experienced the corona effect.

Hijab Fashion Small and Medium-Sized Enterprises (SMEs) need to develop competitive advantages brands as a source of SME competitiveness. However, most Hijab Fashion SMEs experience limitations in developing the competitive advantages of their brands. This research was conducted to find out and understand the competitive advantages of Karleen Hijab Fashion SME competitors as the object of study. The method used is sentiment analysis using the Naïve Bayes algorithm. Sentiment analysis was carried out using online review data of Shopee e-commerce. Sentiment analysis data processing was done using orange data mining software. Sentiment analysis using the Naïve Bayes algorithm produced an average value of AUC, CA, F1, Precision and adequate recall for the entire Hijab Fashion SME brand, which is 0.72, 0.887, 0.856, 0.833, and 0.887. Based on the percentage of the largest positive sentiment on each fashion quality attribute, it is known that competitive advantages of Lozy are in the Fabric Quality Attribute (30.77%), and Good Fit (15.38%), and Halwa's competitive advantage is in the Design attribute (34.19%). Competitive advantages of Hijup are on the Serviceability Attribute (21.74%) and Packaging (15.38%), and Competitive advantages of Lafiye are on the Price Attribute (6.17%). Competitive advantages of Deenay brand are on the Reliability Attribute (20.89%), while Karleen does not have a relative advantage on any fashion quality attribute because the percentage of positive sentiment for each attribute is still below competitors.

A quadcopter can be manually controlled or can be autonomous. Therefore, a control system is needed to support the quadcopter's movement. PID and fuzzy control are used in this research to adjust the quadcopter's altitude position. The control system proposed in this research is to keep the quadcopter at a certain altitude. The control system design uses a PID controller, where the control parameters are obtained using the Ziegler-Nichols 2 tuning method. Ziegler-Nichols 2 tuning method is used to obtain the parameters Kp, Ti, and Td. PID control tuning becomes a reference for fuzzy control design in determining input and output membership functions and the rules. Also, in this study, the flight controller board design is proposed. The experiment results show that the PID control has a faster rise time of 0.2 seconds, a better maximum overshoot of 1.56%, a quicker settling time of 1.69 seconds, and a steady-state error of 0% compared to the fuzzy control. The result shows that the use of PID control is more suitable for proposed quadcopter plants because it requires a fast output response.
