Field Work Practices are part of achieving the expected competencies in the educational process. The suitability of students to companies that serve as street vendors is something that is important to note. The weakness of the previous field work practices system was that there were still many students who were inaccurate in choosing a company or institution as a place for street vendors. This study aims to help determine industry partners in accordance with the competency achievements of each department. The method to be used in this research is Fuzzy Analytical Hierarchy Process (FAHP) in the process of determining the weight priority of each criterion and the TOPSIS method in carrying out the ranking process. The criteria used are the suitability of the department with the company's core (C1), company credibility (C2), and company commitment (C3). corporate environment (C4), and the facilities provided (C5). Each of these criteria consists of several sub criteria. The weights of the criteria obtained through the FAHP are  Furthermore, the process of ranking 37 companies using the TOPSIS method obtained the highest preference value, namely 0.8157.

This optimization is an optimization case that organizes all possible and feasible solutions in discrete form. One form of combinatorial optimization that can be used as material in testing a method is the Traveling Salesman Problem (TSP). In this study, the bat algorithm will be used to find the optimum value in TSP. Utilization of the Metaheuristic Algorithm through the concept of the Bat Algorithm is able to provide optimal results in searching for the shortest distance in the case of TSP. Based on trials conducted using data on the location of student street vendors, the Bat Algortima is able to obtain the global minimum or the shortest distance when compared to the nearest neighbor method, Hungarian method, branch and bound method.

Application Programming Interface (API) is a function concept that can be called by other programs. The API works as a link that unites various applications of various types of platforms, commonly known as API public names. The public API has been widely spread, while its users, programmers who want to search for public APIs, must browse through various methods such as general search engines, repository documentation or directly in web articles. The user does not yet have a system specifically for collecting public-public APIs, so that users have difficulty in performing API public link searches. The solution to these problems can be solved by building a web framework with a search engine interface that provides specific public-public searches for the API, so that users can search the API public more easily. Web Service is an API that is made to support the interaction between two or more different applications through a network. Representational State Transfer (ReST) is one of the rules.

The guesthouse management process of PT PPA is done conventionally, the Group Leader (GL) and the admin coordinate face to face for data collection or changes in employee data on the homestead dwellers. Temporary data collection is done by paper, then entered by MS. Excel. Reporting on homesteads is done by MS. Excel. If there is a change in data, then the reporting of the guest house is invalid. The researcher's goal is to implement a guesthouse management application to accommodate real-time data collection by the Group Leader. Reporting on the residents of the guesthouse can be done based on the date of the guesthouse management transaction. Testing is done by black-box testing and user acceptance test (UAT). All test results are functionally successful, and the test is carried out by the IT department. Based on the UAT test, the mes management application has an attractive appearance, is very easy to use, is very helpful for room relocation, is very in accordance with the proposed design, is very well organized by employees' rooms, is very suitable for the data entered and passwords can be hidden very well.   Index Terms—guesthouse; homesteads; management; reporting; User Acceptance Test (UAT)

SDS Waladun Sholeh merupakan salah satu sekolah swasta di Kabupaten Tanah Laut yang terdampak virus Covid-19, sehingga kegiatan belajar mengajar harus dilakukan secara online atau daring (dalam jaringan) dengan memanfaatkan teknologi komputer yang dilengkapi jaringan internet. Hal tersebut bertujuan agar materi pembelajaran tersampaikan dengan baik kepada peserta didik. Metode pelaksanaan pengabdian terdiri dari 3 (tiga) tahapan yaitu tahapan persiapan berupa koordinasi dengan panitia SDS, tahapan pelaksanaan berupa pelatihan penggunaan 2 (dua) aplikasi pembelajaran besutan google yaitu google meet dan google classroom dan yang terakhir tahapan evaluasi. Pada tahapan evaluasi peserta diminta untuk mengisi kuisioner sebelum dan sesudah pelatihan, hal ini dilakukan agar panitia pengabdian dapat mengetahui tingkat pemahaman dan keterampilan peserta dalam menggunakan google meet dan google classroom. Berdasarkan hasil evaluasi tersebut terlihat peningkatan pemahaman dan keterampilan peserta dimana rata-rata nilai peserta sebelum pelatihan adalah 59.8 sedangkan setelah pelatihan dilakukan rata-rata nilai peserta meningat menjadi 91.42.
