Abstract

Introduction: Since the outbreak of Corona Disease-19 (COVID-19) spreads all over the world, various ways of health attempts have been conducted. However, overflowed information intertwines with mis/disinformation could raise public anxiety and stigma-related diseases. We aimed to assess the help of the young generation of millennials and Gen-Z whom are active college students in debunking hoaxes and myths of COVID-19 into their community.Method: The selected students were given a short course on COVID-19 basic information, prevention, and circulated myths. Later, they become ambassadors and actively educated via offline and online platforms. The impact of outspread information on audiences was investigated through a qualitative survey.Result: The knowledge of students were measured by pre- and post-test within the short course. Prior knowledge showed the least understanding part was prevention and myth of COVID-19. There was a significant improvement of knowledge in post-test after receiving seminar (p=0.0002). There were 97 respondents who filled the online survey that predominantly in young adulthood age. Respondent's insight was enhanced and they likely intend to spread the actual information to their surroundings.Conclusion: Appointing student as the spokesperson for health education can raise their social responsibility. Clarifying misinformation and health behaviour could be more influential within the same sharing community. In addition, the use of various online platforms could efficiently reach massive target, especially young ages.

Abstract

The use of engines that motorized the world based on fossil fuel sources has led to many problems, such as air pollution, energy security, global warming, and climate change. To prevent further damage reducing the application of fossil fuel as a source of the motor is crucial. Hence, utilizing an electric motor could be the solution to reduce the application of motors based on fossil fuel. Among the number of electric motors, permanent magnet synchronous motor (PSMS) is becoming more popular due to their efficiency. However, the challenge here is how to design the controller of PSMS, especially the speed controller. Hence, this paper proposed a design of a speed controller of PSMS using a PI controller. The hybrid differential evolution algorithm-particle swarm optimization (DEA-PSO) is used to optimize the PI controller for better performance. From the simulation result, it is found that the proposed method can enhance the performance of PSMS.

Abstract

Integration of photovoltaic (PV) based power plant have been increased significantly over the years. The integration of this devices is ranging on the small-scale capacity such as in distribution system and large-scale capacity such as in transmission system. Although, PV generation could provide sustainable and clean energy to the grid, they could also bring new challenge on the system stability. One of the stabilities of power system that can be affected by integration of this devices is small signal stability. Hence, it is important to capture the dynamic model of PV generation. This paper is on investigation of dynamic model of PV generation for small signal stability analysis. The simulation is carried out in MATLAB/SIMULINK environment. From the simulation results, it is found that by capturing the dynamic model of PV generation, the modes of the PV generation can be captured.

Abstract

Community service has been carried out in Pasuruan, Eastern Java. A hydroponics farming system, run by a group of farmers in Kecamatan Gempol, consumes electric energy provided by a 900 Wp solar power system. The power plant is equipped with two batteries, 12 V 100 Ah, with a Depth of Discharge (DoD) of 80% each, which enables the power system to store the energy of 1920 Wh as a reserve. According to the farmer’s report, one of the essential components in the solar power system was damaged twice due to lightning strikes at an adjacent time. Also, the hydroponics system is unable to run all night continuously due to the insufficient capacity of the storage system. Therefore, surge protection devices (SPD) are installed in the solar power plant system to protect crucial components from damage caused by lightning strikes. Furthermore, this activity adds two more batteries to the system that double the energy reserve to extend the operating hours of hydroponics electrical equipment when sunlight is unavailable. The work also created a new hydroponics platform with 126 holes as a part of capacity expansion to meet the market demands. Extra protection against insects is also provided by shielding the hydroponics platforms close to the bushes with the insect net.

Abstract

In collaboration with a group of hydroponics farmers, an activity as a part of community service implementation has been carried out in Pasuruan, Eastern Java. The activity aims to develop a 900 Wp solar power plant capable of providing energy for running the essential electrical devices for the hydroponics system uninterrupted. This idea is to resolve the energy issue when the outage occurs. Moreover, the reliance on the public grid also adds additional expense for the electricity bill. Based on the observation, the power plant reliably provides sufficient energy to turn on different hydroponics electrical devices. It can supply energy for 12 hours without charging to activate, in total, 160 Watt of diverse loads all night long. While during the day, solar panels deliver energy for the batteries recharging and the other loads. Some other facilities are also developed in this activity, including UV plastic roof and addition of the grow lights to promote the plants’ growth acceleration. The plastic roof efficiently reduces the sunlight intensity to lower the heat experienced by the plants, transmits specific wavelengths crucial for growth, and prevents the rainwater from entering the nutrient water tank. Meanwhile, the grow lights stimulate faster growth and quickly recover the plants after receiving much heat that causes them to look wilt. As a result, the farmers are now less reliant on the public grid, and the hydroponics system is more weather-resistant.

Abstract

Hydroponics is one of the agricultural techniques with great potential to produce plant products. Hydroponics is also a pattern of plant breeding that is environmentally friendly and does not require a large area of ​​land. Although it has been developed for long time ago, the quality and quantity of hydroponics does not really give significant results. In order to improve the quality of agricultural products, a modernization step is needed by implementing an automation system based on Internet of Things. Thus, the solution offered to overcome the problems of the current hydroponic system, the innovation offered is green hardware, namely Airlangga Sahabat Petani Hidroponik (Arsenik). In this hardware, monitoring of the system with an integrated manner and measuring several aspects such as environmental and soil levels, nutrients in plants and interpreting them into an output that can be read directly by users. The expected result through this hardware is community empowerment in developing hydroponic systems and maximum hydroponic plant yields.

Abstract

This paper presents an examination study of 11 autofocus algorithms for printed circuit board (PCB) automated optical inspection (AOI). A selection of an optimal algorithm for that application based on some criteria was carried out. Unlike microscopy, PCB optical inspection does not require very high magnification. The object in this work was also different from that of microscopy and thus influenced the image features. We analyzed 47 PCB images, size of 640×480, sequentially captured every 1 mm in the z-direction. This work utilized USB digital microscope, and the magnification was set at ten times. Each algorithm calculated the sharpness values of the image sequences, and the plot of the sharpness profile was created. Moreover, the research also carried out experiments in several strategies, including image resizing and applying the non-local means (NLM) denoising filter to assess the algorithm performance in different situations. The algorithms were examined and ranked based on five criteria, i.e., computation time, full width at half maximum (FWHM), accuracy, number of half maxima, and range. The experimentation results showed that the Brenner gradient worked best for analyzing images both in their original dimension or resized images.
