A Reliability Analysis Of Supercapacitor Energy Storage In Multi Engine Unlimited Bus Systems Using The Critical Paths Method
Get PDFIn modern industry, industrial revolution 4.0, energy storage systems are becoming increasingly important to support reliable and efficient performance. One of the technologies used in energy storage systems is supercapacitors. where Supercapacitors offer advantages in terms of high energy charging and discharging speeds, long service life, and the ability to withstand extreme temperatures. One of the characteristics of this power plant is the instability of the power released by this plant due to varying wind speeds. One solution to overcome this is to add energy storage to the generating system which works as power smoothing so that the power sent to the load can be maintained constant. This system can work as an energy store when the power released by the generator exceeds the power required by the load and can be an energy source when the power released by the generator is less than the power required by the load. The problem with energy storage in general is that the usage cycle tends to be low. Supercapacitors, with their characteristics of high power density, high efficiency and high usage cycles, are considered capable of overcoming the problems of other energy storage systems. This final project contains a study of the use of supercapacitors as energy storage in wind power plants, with a focus on comparing several parameters of supercapacitors with lead acid batteries. Based on the simulation results in this research, it can be concluded that supercapacitors have a power density and number of life cycles that tend to be higher than batteries, but have disadvantages, including a small energy capacity and relatively more expensive costs compared to batteries. Supercapacitors can also work as power smoothers to keep power on the DC link constant
Communication Amongst Village Women's Groups As A Catalyst For Social Development
Get PDFThis research examines the role of communication among groups of village women as a catalyst for social development through a literature review method. Effective communication within village women's groups has great potential to improve various aspects of social development, including health, education and economic empowerment. However, challenges such as cultural barriers, infrastructure limitations, and internal conflicts can reduce the positive impact of communication. External support and strong leadership have proven important in facilitating productive communication. The research results show that good communication can increase access to basic services and strengthen participation in social programs. This research emphasizes the importance of a holistic approach to overcoming challenges and maximizing the benefits of communication in rural women's groups, as well as the need for further research to develop more effective strategies
An Application Of Infrared Sensors In Providing Instructions For Logic Gates In Automatic Doorstops
Get PDFA parking space unit is an effective square measure for placing one vehicle (passenger car, bus/truck, or motorbike). This includes free space on the left and right of the vehicle meaning that the doors can be opened for passengers to get on and off as well as certain things such as space for special wheelchairs to park vehicles for people with disabilities as well as free space at the front and back. Parking Gate Bar, or by another name barriergate, is a device for restricting entry and exit of vehicles, the function of this parking door barrier or parking barrier is to indicate that a vehicle is allowed to enter or leave the parking lot, after passing through the parking guard post. Parking door barriers are usually operated using direct DC or AC electricity. , depending on needs and the price level which is adjusted to field conditions. The speed of the parking gate opening is one of the points that determines the price for the item, because the speed of opening will affect the overall parking service cycle, if the parking gate opens faster, more vehicles will be served. , whether leaving or entering the parking area, and ultimately parking customers will be more satisfied, if this speed reduces the waiting time of parking customers
Analysis Of The Effect Of Implementing Work Culture And Leadership Style On Employee Performance Levels
Get PDFIn this study, researchers were interested in researching with the aim of finding out how much influence the partial and simultaneous application of work culture and leadership style has on employee performance. This research uses a quantitative method approach with data collection techniques through distributing questionnaires and is supported by secondary data. The data analysis method used in this research is multiple linear regression analysis. The number of samples used was 50 respondents from employees of the Administration section of Radio Republik Indonesia (RRI) Jakarta, the sampling technique used was saturated sampling. The results of this research show that partially the Work Culture variable (X1) has an influence of tcount 4.056 >ttable 2,012 and Leadership Style (X2) is tcount 3,089 >ttable 2,012. Simultaneous test results obtained a count of 28,917 > F table 3.20. So simultaneously there is a positive and significant influence on the performance of (Y) Radio Republik Indonesia (RRI) Jakarta employees. The employee performance variable can be explained by work culture and leadership style variables of 55.2% and the remaining 44.8% is explained by other variables not tested in this research
Development of Sales Employee Monitoring System in Integrated Performance Measurement Using Prototyping Method
Get PDFMeasuring employee performance is a critical component of ensuring the success and sustainability of a business in a competitive and dynamic business environment. The objective of this research is to create a web-based employee performance monitoring information system that can address the obstacles associated with managing employee performance, including data inaccuracy, reporting delays, and a lack of visibility of employee progress. The prototype method was employed to design this system, which enables the system to be developed iteratively in response to user feedback. This system's primary capabilities include the ability to access and revise employee data, prospects, and performance reports in real-time. The black box testing method was employed to evaluate the implementation of this system, and the results indicated that all of the features that were developed were valid and functioning properly. Ultimately, this system will facilitate more appropriate decision-making and increase company productivity by enabling companies to more effectively monitor employee performance. In summary, the information system for monitoring employee performance that has been developed provides a practical and effective solution to the numerous obstacles that organizations encounter when administering their performance
