Abstract

The surge in positive cases of Covid-19 in Indonesia has increased the demand for medicines and vitamins. As a result, many residents visited the village health center, pharmacies, and drugstores to buy medicine or vitamins to boost their body's immunity during a pandemic. health protocols that limit room capacity result in queues of buyers snaking which can lead to the potential for new infections. The World Health Organization (WHO) itself urges people to implement contactless payments, by using e-money or using electronic payments and avoiding touching touchless devices. This research is a continuation of the activity plan for Community Service at the Jatimelati village health center Pondok Melati Bekasi. Machines providing medicines that accommodate contactless and face-to-face contact with officers are deemed necessary to meet the needs of medicines and vitamins as a complement to machines providing medicines and vitamins so that people can get them more easily during and after the pandemic. In this study, this drug supply machine is equipped with a payment system using a balanced RFID card such as e-money and is also integrated with the website to facilitate monitoring of drug stock availability.

Abstract

Nowadays, energy sources in the world at the end until now tends to be filled using fossil fuels. It is estimated that the world energy consumption until 2025 is still dominated by fossil fuels, namely oil, natural gas and coal. The Ministry of Energy and Mineral Resources said that petroleum dominates 54% of energy use in Indonesia. One way to overcome the use of fossil energy sources is to replace them with renewable energy especially photovoltaic. Therefore, this paper presents solar charge system using Buck Converter PID Controller for Spotlight load. Buck Converter with PID Controller is used to produce a smaller and more stable output voltage from solar panels of 14.4 Volts for charging the battery. The PID parameter values ??obtained after performing calculations using the Analytic Tuning method and tuning are Kp = 0.0307, ??Ki = 58.20 and Kd = 0.000263. The expected result of this research is to design and implement a solar charge controller as a producer of electrical energy from environmentally friendly energy.

Abstract

The selection of an appropriate number of blades for a propeller is a critical factor in the design and performance of UAVs. This study aims to analyze aerodynamics. The analytical methodology employed in this research involves computational fluid dynamics (CFD) simulations using state-of-the-art software. A parametric study is conducted to evaluate the effect of different blade numbers on various aerodynamic performance metrics, such as dynamic pressure, static pressure, velocity, and force (Y). These simulations are carried out over a range of operating conditions, including varying airspeeds and altitudes. Our findings reveal that the number of blades significantly influences the aerodynamic characteristics of the propeller. Based on the CFD results, the type of propeller generates a different characteristic of aerodynamics. It will produce more static pressure, dynamic pressure, and velocity if we add the number of blades to it. But, with the CFD process we know that if we need to generate more force, especially in the (Y) axis as the representation of thrust on UAV, we need to consider using a propeller with a 2-blade or 4-blade that generates more thrust efficiently with 367.79 N and 450.59 N respectively rather than 3-blade or 5-blade. Because if the number of blades is added it will cost more pressure either on dynamic or static and velocity value but not following by force (Y) value. Using 200 the trajectories are enough to represent the aerodynamic characteristic produced by each type of propeller.

Abstract

This study explores an alternative method of generating electrical energy using a thermoelectric generator that utilizes heat from the soleplate of a steam iron and six thermoelectric units connected in series. Based on the Seebeck effect, the thermoelectric modules convert the temperature difference into voltage. An increase in the heat source temperature leads to higher voltage production by the series-connected thermoelectric modules, although the electrical power output depends on the connected load. The power generator design includes thermoelectric modules, a buck-boost converter, an 18650 lithium-ion battery, and a 5-watt, 12-volt DC lamp. The study addresses key aspects such as the impact of temperature on power output in series-connected and parallel-connected thermoelectric circuits, and the efficient conversion of heat from the steam iron soleplate into electrical energy. The research objectives are threefold: to determine power and temperature values for series-connected thermoelectric circuits, to evaluate power and temperature values for parallel-connected thermoelectric circuits, and to utilize heat from the steam iron soleplate as a thermoelectric heat source for generating electrical energy. Testing involved a buck-boost converter connected to a battery, producing 12.35 volts with a temperature difference of 49°C. Design enhancements, such as integrating heatsinks or coolers on the cold side of the modules to maintain a significant temperature differential, are critical for optimizing performance.

Abstract

An electric vehicle charging station (EV charging station) is an infrastructure designed to charge electricity for electric vehicles. However, most EV charging stations still rely on fossil energy sources. Innovation is needed to overcome this problem. One of them is through the use of solar panels. Using solar panels on the CBMS turns it into a clean and environmentally friendly energy source. However, environmental factors such as weather significantly affect the energy conversion produced by solar panels. Panels that are covered by trees and tall buildings cause partial shading conditions. Partial shading conditions can result in a direct decrease in PV output power. To overcome this, output power optimization using a DC-DC converter is required. The MPPT boost converter system with a modified P&O method is designed to maximize the output power of solar panels when partial shading occurs. The test results show that the developed system can maximize the output power of solar panels in partial shading conditions with an average power increase of 8.13 and an efficiency of 91%. This method can reduce the negative impact of changes in light intensity, keep the system close to the maximum power point, and improve the efficiency of charging electric vehicles at SPKL during unstable weather conditions. However, the modified P&O method is less effective in maximizing the output power in standard solar panels. This research does not address the effectiveness of solar panels concerning temperature, humidity, and dust.

Abstract

his research introduces an innovative drone-based air quality monitoring system, equipped with multi-parameter sensors to measure temperature, humidity, CO2 concentration, and PM2.5 in real-time. The system is designed with integration to the Internet of Things (IoT), enabling direct data transmission to smart devices for instant access and quick analysis. This system provides a practical solution for monitoring air quality flexibly, especially in areas that are difficult to reach with conventional monitoring devices. Simulations showed that the drone canoperate for 4.8 to 14.77 minutes with an 80% battery depletion, depending on environmental conditions. Calibration testing of the sensors showed high accuracy, although data variations were significantly affected by temperature changes. The system underwent trial and calibration as an initial step to ensure device reliability and open opportunities for broader application development, including air quality monitoring in urban areas, industrial zones, and natural environments. The main advantage of this system lies in its ability to provide real-time data and flexibility in data collection from various locations. However, the study also identified several challenges, such as battery capacity limitations and communication range, which will be the focus of further development. Potential improvements include optimizing battery capacity, expanding communication range, and developing predictive
