Abstract

This article discusses the modeling and analysis of Photovoltaic (PV) modules with irradiation and temperature variations using simulation technology. Modeling is carried out on solar modules through the p-n junction principle, a PV module model with temperature independence of photocurrent sources, diode saturation currents, and series resistances based on the Shockley diode equation. The photovoltaic process of solar radiation, PV cells convert a portion of the photovoltaic potential directly into electricity with I-V and P-V output characteristics. Electromagnetic radiation from the sun's energy is converted into electricity through the photovoltaic effect. The photovoltaic module simulation process with Matlab/Simulink, is carried out to observe the performance through the I-V and P-V characteristics of the solar module. The model, which is developed in a user-friendly manner using the Simulink block, shows the results of the PV characteristics when irradiation increases, the output current increases and the output voltage also increases. This results in a net increase in power output with increased irradiation at constant temperature.

Abstract

This study aims to implement Google Maps API technology and the Havershine algorithm in the Emergency Reporting System (ERS) application at the Polrestabes Makassar, where this system runs on Android with quick access for user using the buttons on the screen and the volume up button. System development in this application uses the waterfall method with the UML (Unified Modeling Language) design language. Meanwhile, software using JAVA, PHP, HTML, CSS, Java script and MySql is used for database management. Data collection was obtained through observation, interviews and literature study. Based on the results of testing by 18 respondents consisting of 12 members of the public or reporters and 6 officers, it was found that the average percentage of respondents' scores for questionnaire questions was 82.5% with a Cronbach's Alpha value of 0.73. It can be concluded that the emergency reporting system application is considered very reliable. Testing this application using a button on the application screen ran smoothly on the first try with the average time the victim pressed the button to record less than 1 second or 0.64 seconds and the time it took for a message to reach the helper or police officer was 11.66 seconds. Testing the emergency notification application using the volume up (+) button on the device completed smoothly in 1.55 trials with the average time between the victim pressing the volume button and recording being 5.00 seconds and the time until the rescue team arrived was 14.00 seconds. This time includes the time required to set the maximum volume and activate the device screen. The percentage of correspondence between the accurate location points of the reporter and the recipient of the report using the Google Maps API with the Havershine algorithm to determine the relevant police station based on the closest distance is approximately 75% accurate on average with a distance difference of approximately 45.5 meters.

Abstract

Internal cash control is a control process to achieve specific goals. Internal control is carried out by people from each organization, including management and all employees. Internal control is expected to provide reasonable assurance to managers and employees in an organization. The data analysis method in this study uses simple linear regression to predict the effect of independent variables. The population in this study amounted to 100 employees in the Aceh SKPD. The results showed that the use of information technology affected the implementation of internal cash control. However, it indicates that information technology can play an essential role in the performance of internal cash control in the Regional Work Unit (SKPD). By utilizing information technology, SKPD can improve efficiency and effectiveness in controlling and managing cash internally, such as identifying potential fraud or weaknesses in the cash control system, monitoring financial transactions in real-time, and making more accurate and transparent financial reports.

Abstract

Delays in the payment of wages can occur in several situations, for example, when the shop owner is experiencing financial problems or when events disrupt the grocery store's operation. However, delaying the payment of wages without a valid reason and the employees' consent may violate labor laws. It may negatively affect the relationship between the grocery store owner and the employees. Suppose a grocery store is experiencing financial problems and cannot pay wages on time. In that case, it should clearly and transparently inform employees of the situation and provide assurances that wages will be delivered as soon as possible. Grocery stores must also make efforts to find appropriate solutions, such as finding funding sources or carrying out financial restructuring to pay employee wages on time. The research aims to look at the practice of delaying the payment of workers' salaries in Sigli City. The research method that the author uses in this research is descriptive analysis, with the research approach used in this research being qualitative. The results showed that the Cahaya Family grocery store never experienced delays in salary payments. Still, there were also delays in salary payments because there were workers who were allowed to go home during the day. Only at H. Nurdin's grocery store where the salary payment was late, and the reason for the transaction needed to be explained in detail.
