Abstract

Students at SMA Negeri 1 Central Bengkulu are still dominated by the manual method, namely taking student absences by recording them on paper which will later be summarized from each student's attendance data. Because the manual recap of student attendance data also affects the information about attendance recaps which is still limited to the school, so parents/guardians cannot monitor student attendance levels. Inconsistency in attendance data can be detrimental to students, there is often a difference between the absences listed in the attendance register book/record into the system, which is one of the factors that makes the original data and data that have been verified into the system different. Utilizing the location of an Android smartphone to become an attendance system, which functions to provide location information based on the user's nearest location, assisting in searching for locations based on 6 existing parameters, namely education (high school/vocational school/university), hospital, hotel, restaurant, tourist attraction , and malls/traditional markets. It is hoped that this application will always be up to date so that this application follows developments in Android-based lecturer/teacher attendance information technology using the Flutter framework.

Abstract

This study aims to evaluate the effect of ramie fiber length on the tensile strength of Fiber Metal Laminate (FML) hybrid composites. The background of this research is the saturation with the use of synthetic composite materials, which encourages the search for renewable materials to replace synthetic fibers. In this study, ramie fibers were immersed in a 6% NaOH solution before use, and the composite manufacturing process was carried out using the hand lay-up method. Annealed Aluminum 1100 was used as the laminating layer. The results of the study showed that the highest tensile strength was obtained in composites with a ramie fiber length of 5 cm, with a tensile strength of approximately 105 MPa. These findings indicate the potential of using ramie fibers as a sustainable and efficient alternative in FML hybrid composite applications.

Abstract

State regulations state that village funds come from the State Budget (APBN) and are used to support governance, development, development, and social activities as well as community empowerment. It is hoped that the existence of village funds will increase the sources of income for each village, and the addition of village income by the government will improve public service facilities.1. As a result, a sentiment analysis of village officials will be carried out in this study. The Naive Bayes approach will be used to classify public sentiment as part of this investigation. We will evaluate two methods to see which produces more accurate results. In addition, the village government's function as the most important social institution in the community is essential for setting standards, facilitating socialization, and allocating resources. Furthermore, some Eweta community members have not received assistance, which could cause social rivalry among neighbors. Through sentiment categorization, responses will be categorized as either positive or negative. Based on feedback from visitors, this study attempts to assess the validity of the two approaches put to the test and offer insights into the caliber of services rendered by the village administration.

Abstract

At every educational institution there is a library for students to use at that institution. Likewise with SMP Negeri 2 Wewewa Tengah. At the school there is a library but it still uses a bookkeeping management system or is still written manually, while the number of active borrowers is almost all students carrying out the borrowing process at the school. The process of borrowing books in the library begins when students come to the library and tell the library staff that they want to borrow books. Then students select the books they want to borrow on the shelves provided. Next, the library staff records the borrower's data, such as full name, student identification number, and class, as well as data on books borrowed, such as book title, author, and inventory number in the ledger used as a borrowing register.). The school library has a strategic role and function in developing the potential of students from the entire academic community in the school environment. The library is part of the learning resources that every school has, a library that is still manual is something that needs to be created a system that can help with administrative activities. With the e-library, users can access it together with other users without having to wait in line. The search process is easier and faster because it is assisted by an information search engine that uses a database. This system presents a variant of the digital library, including a user page section that presents books available at the Central Wewewa State library
