Solar radiation could be used as alternative energy by using solar panel as a transducer to convert solar radiation energy to electricity energy. Jamal SSFarm, a family-owned business in decorative fish cultivation had problem in electricity energy limitation for their operational works. Researcher and team offered solutions to install and implement solar energy as an alternative energy by using solar panels. This community service works have done by two steps, the first step was surveying and buying stuffs and the second step was installment and testing at the partner location. In our activities, the alternative energy system works well. The testing device showed 1.25 ampere of its current, which shows that the device works well. That matter are in line with our partner expectation.

Permanent Magnet Synchronous Motor (PMSM) applications include electric vehicles, industrial pumps, wind turbines, aerospace technology, and many others. In this study, cogging torque is the central aspect of the discussion, which is the motor model, the thickness of the permanent magnet rotor, and the air gap in the electric motor influence. The Taguchi method uses parameter levels on the motor, which are divided into 16 types of orthogonal arrays, where the process is carried out twice in iterations. The first stage of simulation testing was to produce the primary model where number 4 (A1B4 series) was obtained as the most optimal motor model with a cogging torque of 1.56 Nm and an air gap flux density of 768 mTesla (mili tesla). Then the second test was to modify several parts of the motor with the following 16 orthogonal array types, which produced number 8 (A2B4 series) with a cogging torque of 1.08 Nm and an air gap flux density of 733 mTesla. One of the parameters apart from the cogging torque must be maintained is the air gap flux density. This variable affects the permeability of the motor so that later it will affect the amount of material used and the production costs of electric motors. The final result is a model that produces the lowest cogging torque while maintaining other parameters on the motor.

The voltage sensors are widely used in various applications. In certain applications, such as medical devices, autonomous vehicles, or the military, the sensor's accuracy and level of precision play an important role, making it necessary to evaluate the sensor's performance. In this research, testing of direct current (DC) voltage sensors was carried out using analysis of variance (ANOVA) and Tukey honestly significant difference (HSD) to test sensor performance in various voltage ranges. This research used an experimental-based quantitative approach, using the ATmega328P. Data collection begins by calibrating the analog-to-digital converter (ADC) readings against voltage values with linear regression, the Chauvenet criterion to eliminate outlier data caused by noise from the environment, One-way ANOVA is used to determine differences in variations between voltage distances, and a Q-Q plot is used to determine the normality of the sensor error distribution. This research obtained from Tukey-HSD that 9 comparisons accepting the null hypothesis (H0). And 27 pairs accepting the alternate hypothesis (H1). The data was found to be normally distributed through the calculation of residual ANOVA, and visualization of data with the Q-Q plot, and the use of the sensor was effective in the range of 3V to 24.5V.
