An algorithm is an effective method or steps arranged in writing and sequentially containing a collection of commands to solve a problem. Every problem must be resolved logistically, systematically and organized. Programming is a process that allows computers to solve or solve problems in the form of solving steps, as done in programming code languages, so that computers can actually solve problems. A programming algorithm is a systematic collection of steps aimed at solving any computer programming problem. Based on the writing format, the application of the programming algorithm is descriptive, pseudocode, and flowchart. And the basic structure of a programming algorithm can be used in three forms: sequence, selection, and repetition. Algorithm writing is not governed by any particular rules; however, each step of the algorithm must have a clear goal. The purpose of writing this article is to study the functions and various implementations of programming algorithms and their applications in everyday life. To achieve this goal, this article was written using the literature study method, which means reading systematically and in an organized manner books, journals and other sources related to programming algorithms. Programming algorithms have many very important functions. Solving a problem is the main function of a programming algorithm. Algorithms function to simplify programs, make it easier to find errors, and minimize repetitive program writing. Programming algorithms also have implementations and functions for us in everyday life. Examples of algorithms in our daily activities, such as installing applications, sending emails, receiving payments at ATMs, making fried noodles, making cakes, making coffee, riding motorbikes, cooking rice, etc.

Toast is a common and popular food all over the world. Toast is generally made from slices of bread that are toasted until golden brown on the outside and soft on the inside. The basic bread used varies, from white bread to whole wheat bread, and can be cut in various shapes. The toasting process is a key stage in making toast, where the pieces of bread are toasted until they reach the desired doneness. Fillings are an important element in toast, with various options such as butter, jam, cheese, chocolate and nuts. Bread ingredients such as bread, butter, canned milk, etc. are a problem. If one of these ingredients is not met then production in the bakery business will be hampered. Therefore, to find out what variables hinder optimal value in the bakery business, mathematical modeling can be created using the simplex linear method program.

Education is the main foundation in community development and human resource development. In the context of higher education, the quality of the learning process and lecture management greatly affects student success. One aspect that has a significant impact on the learning process is student attendance management. Traditionally, recording student attendance is done manually by using a physical attendance list that must be filled in by students and signed by lecturers. Although it has been used for a long time, this method has a number of limitations that need to be overcome. In the rapidly evolving digital era, we have access to technology that can simplify and improve student attendance management. The use of information technology can provide a more efficient, accurate, and practical solution in recording student attendance. The app was developed using MIT App Inventor, a platform that makes it easy for users to create Android apps without in-depth programming knowledge.

Such quick change in information technology and computers have required changes in the educational paradigm, particularly in teaching and learning methods. Computer applications are software services that use computers as the medium. Programming language is the language used in computing to create programs. An algorithm, a systematic sequence of steps, is used to solve a problem, and an example of one of these is the Winnowing algorithm. The Winnowing algorithm is a document fingerprinting method that utilizes hashing to detect text similarities. In an essay exam, an instructor must carry out a manual assessment by checking and correcting each participant's answers. Currently, automatic assessment is still generally limited to multiple choice questions. The purpose of this study is to investigate the extent to which previous studies have examined the assessment of essay questions using the Winnowing algorithm. The results of the study indicate that the application of the Winnowing algorithm in automatic evaluation of essay responses on online learning platforms (e-learning) provides good and stable results, and has a high degree of accuracy.
