Abstract

The quality of beauty treatment services will be evaluated by the clients subjectively whether they are satisfied or otherwise with the services provided. However, the reports and complaints related to customer dissatisfaction when receiving beauty treatment services at beauty centers are increasing. Unfortunately, the suggestions for improvement from the previous studies are still insufficient. Therefore, this study was conducted to examine the importance of proficiency in communication skills and the need for training modules in the teaching and learning process (T&L). It is required to improve communication skills among cosmetology students for Upper Secondary Vocational Education Program (USVEP) in beauty arts course. The data were collected through the interview method on six USVEP teachers and a beauty salon entrepreneur. The findings of the study found that the proficiency in communication skills among the cosmetology students is an important requirement for employers in selecting their employees, increasing customer loyalty and the customer’s frequency to visit beauty salons, and maintaining the excellent performance of cosmetology students in the workplace. In addition, there is also a high demand for the development of communication skills training modules in helping cosmetology students to constantly updated with new knowledge and skills needed from time to time. Therefore, adequate training is required to improve the competency in communication skills among the cosmetology students.

Abstract

Plant microbial fuel cell (P-MFC) is an electrochemical reactor that converts organic compounds to electrical energy through the catalytic reaction from electrochemically active bacteria (EAB). However, there is no sign of an attempt in developing the functional model in predicting the energy conversion and utilization of P-MFC. In this study, an analytic model is proposed to show the whole production process of the organic compound to electrical energy generation. Pandanus Amaryllifolius plant was used as sources of photosynthate, where biomass product from rhizodeposition, acetate was produced, and soil bacteria as the microbial culture, and air as the input to the cathode chamber. The proposed analytical model is able to predict the output of the P-MFC using the parameters from the experiment. The generated data from the model was then compared with the monitored data from the Pandanus Amaryllifolius P-MFC. The results show the electrical power output has a high similarity pattern with the bacterial growth curve model and able to achieve the coulombic efficiency of 95.32%.

Abstract

An electronic circuit that functions to block or hold signals with intermediate frequencies (median) and will forward signals between low frequencies and high frequencies is the definition of a Notch Filter. The Band Stop Filter, also often referred to as the Notch Filter, is a combination of a Low Pass Filter and a High Pass Filter connected in parallel. This connection differs from the Band Pass Filter, which connects the Low Pass Filter and High Pass Filter in series. This study aims to discuss the simulation of the Sallen-key notch filter Circuit. The author also conducts real simulations to prove the Circuit by changing or adjusting the value of the components installed in the Circuit so that the frequency response is according to the target. The purpose and role of the Sallen-key notch filter and the working principle of the theory of each filter used. The research method used in the research work is to carry out virtual simulations using virtual simulators and live simulations
