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

Abstract

Village development includes village funding, and the community takes the lead in developing and initiatives that advance village welfare are developed through cooperation with the community. Village development is an important instrument that must be used because it directly improves the welfare of the village community. Village communities are the focus of development, and each village is given the authority by the government to carry out its own development according to its capacity. Thus, the government supports the improvement of village development and empowerment. Village funds are used to provide or improve village public services, reduce poverty, advance the village economy, and reduce tandem between villages. This study uses a weighted summation approach of alternative rankings on all attributes, which is often known as the Simple Additive Weighting method. To determine which residents receive social assistance, the system can calculate the value of the multi-criterion preference index, preference value, outflow, inflow, and net flow for each alternative and sub-criterion.

Abstract

One of the government initiatives of the Sobawawi sub-district is Direct Cash Assistance, or BLT, which aims to lessen the financial strain on the population. Not everyone is eligible for direct cash assistance because it is meant to help low-income families fulfill their basic necessities. The government offers cash support to those who are considered impoverished through the Direct Cash support (BLT) program. This program is intended to help those who struggle to manage their financial situation. In order to help resolve and minimize errors when assessing who was eligible to receive BLT (Direct Cash Assistance) in the Sobawawi district, a decision support system was developed in response to the issues that arose throughout the selection process. The goal of this system is to support decision-making processes that employ the Analytical Hierarchy Process (AHP) technique. The results of both system and manual computations demonstrate how the decision-making system uses the AHP method's notion to determine. Based on the method employed, the system delivers findings that are legitimate and accurate. Ultimately, alternate priority weights based on ranking are determined.

Abstract

In order for students to actively develop their potential for religious spiritual strength, self-control, personality, intelligence, morality, life sciences, general knowledge, and the skills they need for society based on the law, education is a planned basic effort to create a learning atmosphere and learning process. Invite. Although it can also be autodidactic, education frequently takes place with the assistance of other people as well as biological parents. Preschool, elementary school, middle school, high school, and finally college, university, or apprenticeship are the typical phases of education. Another important factor in a region's development is education. Therefore, a decision support system that can make suggestions for choosing state institutions and study programs is required for West Sumba Regency SMA/Vocational Schools. The Analytical Hierarchy Process (AHP) approach is used to weight the value of each criterion, and the Simple Additive Weighting (SAW) method is used to calculate the weighted total or to order the alternatives from best. The weights of each alternative—a state university or study program—along with all of its features are added up to determine recommendations for selecting one. The chosen option will be indicated by a higher value. This system generates a report on the outcomes of management decisions, which includes the management's selections based on all options arranged from greatest to smallest SAW value. MySQL and Microsoft Visual Studio 2008 were used to develop the decision support system suggestions for choosing state colleges and study programs for the database.
