SIM Accreditation Cloud is a media accreditation simulation facility that is used by the Study Program and BPM in implementing and monitoring the feasibility of the study program whether it is in accordance with the standards that should be in creating a quality culture. In the face of the Regulation of the Minister of Education and Culture (PERMENDIKBUD) No. 5 of 2020 and the regulation of the National Accreditation Board for Higher Education (BANPT) No. 1 of 2020, related to the mechanism for extending the accreditation of universities and study programs that already use the Higher Education Accreditation Instrument (IAPT 3.0) and Study Program Accreditation Instrument (IAPS 4.0), so We need a system that can help Lancang Kuning University in the preparation and implementation of accreditation assessment simulations for both universities and study programs in order to be able to adjust the implementation and preparation of the mechanism for extending the validity period of accreditation for colleges and study programs. However, the fact is that until now there has been no study program that has proposed an extension of the accreditation period using the Study Program accreditation instrument. Lancang Kuning University has 21 Study Programs consisting of 9 Faculties, in implementing an internal quality assurance system, Lancang Kuning University has a Quality Assurance Agency in charge of managing a quality culture, but in the implementation of accreditation with IAPS 4.0 this has not been effective, this is proven to be absent from the study program. who are ready to apply with IAPS 4.0, because there are still obstacles in the preparation of accreditation instruments, while the need for accreditation ratings is very much needed by study programs so that they are able to compete and realize the vision and mission of the study program.

Image captioning task generates a description from an image in a form of a sentence. It holds various critical usage in different applications and domains, such as indexing in retrieval system, by capturing semantic information within the images. In the area of live quality support system, an image captioning model may be used by visual impaired people to achieve visual understanding of their surroundings. In this paper, we present a novel image captioning model that aims to give visual understanding on household environment. To develop the model, we use five different household objects (sinks, chairs, tables, beds, couches) from MS COCO datasets. We create three new captions, in Bahasa Indonesia, for the selected data. The captions describe the name, the color, the position/location, the size, and the type/characteristic of the related object and its close surrounding. InceptionV3 and LSTM architecture is used to train the model with GloVe as the word embedding. In this study, our developed image captioning model can generate caption well and achieved BLEU-1 score of 0.502033, BLEU-2 score of 0.312539, BLEU-3 score of 0.193333, BLEU-4 score of 0.106111, METEOR score of 0.183193, ROUGE-L score of 0.358339, and CIDEr score of 0.348903.

Smart city 4.0 is a development of the three previously published articles, namely smart city 1.0,2.0 and 3.0. The smart city article that we created is a long process in research, so we have to make it gradually and make it into several parts. Smart city 1.0 and 2.0 we designed a big picture of a smart city and how the maturity level understood. Next, in smart city 3.0, our focus is on how smart education can be applied in collaboration between each educational institution so that a high-quality level of education achieved in the area. In smart city 4.0, we focus on designing a concept that focuses on developing tourists and how to get investors interested in investing. Factors such as culture, infrastructure/facilities, human resource development in the community, safety and comfort, profit sharing, development of tourist attractions, innovation in improving people's lives and many other factors are our main concern in this article. The methods used in smart city 4.0 are PDCA & USEPDASA, which are both appropriate methods for developing a special framework for tourists and investors. The stages in smart city 4.0 are mapping in terms of culture, human resources, facilities, information technology, security and comfort. These divided into two parts: on the side of increasing tourists and the side of increasing investors. The result of smart city 4.0 is a framework to be able to connect all activities in a smart city to generate profits for the area.

The need for well-maintained facilities can certainly affect activities in the building. To meet these needs, a building maintenance work program is needed to achieve the planned life of the building. The problem with contractors is that they still use telephone communication to receive reports of any damage to the building. This paper discusses the needs analysis in the construction of a building damage reporting system from the back-end side. The application is built on a web-based basis and provides information about the building in terms of the structural aspect as well as grouping the damage based on the damage criteria. The results of this study are obtained in the form of 10 tables that will compile a system database and transaction analysis that can be done in the system, namely generating building damage data reports where there are four categories of damage, namely light damage, moderate damage , severe damage, total damage and this application can later be used by building managers in reporting building damage through applications and contractors can monitor through applications

Each company has its own standards in giving bonuses to outstanding employees in accordance with the company's rules. So we need a system that is able to solve the problem so that the bonus is given according to the performance of each employee. The problem that often occurs today is in the form of a lack of user knowledge in providing bonuses according to employee performance, so that this research can be used as a reference in giving bonuses to each employee according to performance. The solution for giving this bonus uses a decision-making system using Sugeno's Fuzzy Logic. The Sugeno method is to determine the input variable and the output variable which is a firm set, the second step is to change the input variable to a fuzzy set with a fuzzification process, then the third step is to process the fuzzy set data with the minimum method. And the last or fourth step is to change the output into a firm set with a defuzzification process using the centroid method, so that the desired result will be obtained on the output variable. Solving production problems using a comparison of the Sugeno and Mamdani methods. This method uses constants or mathematical functions of the input variables, and in the defuzzification process uses the centralized average method.

Teaching administration is a teacher's needs that are recorded or recorded into files stored by the school curriculum section. Teaching administration is in the form of lesson plans per semester made by the teacher to be applied based on the planned subject matter. Archiving of learning outcomes data and teaching materials is often ignored so that teachers do not provide subject matter according to the study plan and evaluation of learning outcomes is not satisfactory. In addition, the teacher administration file is a need for school accreditation which is a benchmark for the education office's assessment, which is a serious concern for schools in making reports in their work units. To reduce administrative errors, loss of data and the effectiveness of teaching services and assist teachers in managing lesson plans and evaluating learning outcomes, a tool that is able to provide solutions is needed. Near Field Communication, abbreviated as NFC, is a development tool for Bluetooth and RFID. NFC allows the phone to store important data securely and sent to other phones equipped with NFC or read by an NFC reader. In addition, this NFC allows mobile phones to be developed for the administration of school payments as well as giving class schedules to students. In this study, a teaching administration system based on Near Field Communication (NFC) has been developed using the Raspberry Pi as a microcontroller as well as a computer capable of applying web-based programs. Electronic teaching administration with NFC is expected to replace conventional teaching administration. The advantages of NFC-based E-Teach are that it takes a short time to use, does not depend on internet access and is easy in delivering teacher administration to those in need. Study plan data processing and evaluation of student learning outcomes are faster, more accurate and integrated with the management of education providers.

A sense of security and easy access in managing the house is a must that every home must-have. With advances in technology, it makes it easy for us to manage and maintain the security of our homes, one of which is by utilizing an embedded system in home management using fingerprints. Fingerprints are used as the main key to access the house to provide a sense of security, convenience in managing the house, and minimizing cases of theft that occur in houses that still use conventional keys. based on trials carried out the use of fingerprints is easier to use than using an ordinary key with a success rate in the test, namely 100% in a clean and not wet state, 40% in wet fingerprints, and 0% in dirty fingerprints or dusty.
