Process monitoring conventional parking area is currently still using manual way to know the number and availability of existing capacity in the parking area, the monitoring process carried out in several ways such as recording the number of vehicles entering and see firsthand the state of the vehicle that was parked. The conventional method is certainly cause some problems for both the parking attendant and the owner of the vehicle, where these obstacles include the difficulty to obtain accurate information about the number of parking slots are available as well as difficult to know where to position the parking slot. Automatic parking monitoring system uses a microcontroller arduino uno as a data processor which utilizes multiple types of sensors are placed at some point areas, where the use of these sensors function as an input device that later processed with output an instruction to the servo motor and also the appearance of an information on an LCD screen that displays information about the number of parking slots are available as well as the location of the parking slot. In addition to using the LCD, the tool is also equipped with two indicator lights that show the status of the parking area and a buzzer will sound as a form of notification to the officer and the owner of the vehicle that the state of the car parking area has full.

The numerical method is a technique used to formulate mathematical problems so that they can be solved using ordinary arithmetic operations. In general, numerical methods are used to solve mathematical problems that cannot be solved by ordinary analytical methods. In the Numerical Method, we know two types of system equations, namely the Linear Equation System and the Non-Linear Equation System. Each system of equations has several methods. In the System, the Linear Equation between the methods is the Gauss Elimination method, the Gauss-Jordan Elimination method, the LU (Lower-Upper) Decomposition method. And for the Non-Linear Equation System between the methods is the Bisection method (Share-Two), Falsi Regula method, Newton Raphson method, Secant method, and Fix Iteration method. In this study, researchers are interested in comparing the two methods in the Non-Linear Equation System, namely the Bisection method and the Falsi Regula method. And this benchmarking process uses the Java programming language tool, this is to facilitate analysis of method completion algorithms, and monitoring in terms of execution time and output analysis. So that we can clearly know what differences occur between the two methods.

There are various kinds of data sorting methods that we know of which are the Bubble Sort, Selection Sort, Insertion Sort, Quick Sort, Shell Sort, Heap Sort, and Radix Sort methods. All of these methods have advantages and disadvantages of each, whose use is determined based on needs. Each method has a different algorithm, where different algorithms affect the execution time. One interesting algorithm to be implemented on 2 variant models of data sorting is the Bubble Sort algorithm, the reason is that this algorithm has a fairly long and detailed process flow to produce an ordered data sequence from a previously unordered data sequence. Two (2) data sorting variant models that will be implemented using the Bubble Sort algorithm are: Ascending data sorting variants moving from left to right, and Descending data sorting variants moving from left to right. And the device used in implementing the Bubble Sort algorithm is the Java programming language.

In the field of computer science the efforts made in solving a problem are to use systematic, logical, and strategic flow and steps. These steps are known as algorithms. So many algorithms exist for solving a particular problem. In connection with this paper the algorithm discussed is about the data sorting algorithm, among the few known are: Merge, Selection, Insertion, Bubble, Quick, Heap, Shell. All of these algorithms have advantages and disadvantages of each. One interesting algorithm to be implemented on 2 models of data sorting variants is the Bubble Sort algorithm, the reason is that this algorithm has a fairly long and detailed process flow to produce sequential data sequences from previously unsordered data sequences. And the purpose of implementing them using the language of the program is to be able to provide a translation picture of a complicated and long Bubble Sort algorithm that becomes easier and concise to solve using the program language, which in this case uses the Java program language. For ascending sequencing moving from left to right the method is by shifting the larger values to the right position in sequence, so that finally the smaller values are on the left, whereas for descending sorting moving from left to right the method is by shifting the smaller values to the right position in sequence, so that finally the larger values are on the left. And the programming technique differs only in relation operators that are used against the data being compared.

The conventional attendance system has problems and raises many questions so that administrative management becomes less effective and efficient. The focus of research is on making attendance tools an automatic attendance system by utilizing student cards as a tool to collect attendance data. Methods of collecting data were obtained by direct visits, interviews, and literature review. The analysis method is obtained by comparing the old system with the new one using the system development life cycle. The prototype method used in this research is the rapid prototyping approach. The RFID prototype for the attendance system uses student cards as a tool for attendance. So that the card becomes more useful and multi-functional. The purpose of this research is to help GT Vocational School in making a better automatic attendance system so that the system can make it easier for staff and teachers to manage attendance. The attendance system uses student cards as a tool for attendance, can make students more independent in the attendance process, and teachers just confirm on the website, and they don”t need to bring attendance papers anymore. With the automatic attendance system, all data is integrated into the website, the administrative section no longer prepares attendance papers for each teaching and learning activity.
