The impact that arises is the teaching and learning process must be carried out from home using the online learning method. This teaching and learning method raises a variety of responses from students. This is what makes researchers analyze these views, both in the form of positive opinions or negative opinions. The analysis process is carried out by applying sentiment analysis or opinion mining from the comment on Facebook, text mining is processed using the preprocessing method, labeled it to positive and negative. Based on the available data, a classification process is carried out using the K-Nearest Neighbors algorithm. Rapid Miner is used to experiment text data with the KNN algorithm in order to find the value of accuracy, precision and recall. From the results of research, it was obtained a value of 87.00% for accuracy and 0.916 for the AUC value. The values are high enough for the classification of student opinion against this pandemic so that this research is classified as Excellent Classification.","PeriodicalId":309539,"journal":{"name":"Ultima InfoSys : Jurnal Ilmu Sistem Informasi","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122949431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PT Ikido Jorr Indo Sepatu is a manufacturing company that produces shoes for babies, and toddlers. The authors find problem such as most of its business processes still do not take full advantage and not optimally using IS and IT, and sometimes problems in the form of human errors, such as writing wrong memos, wrong data entry, and not having “real time” data processing between each of company division that can interfere with ongoing business processes. Therefore the authors will design a company enterprise architecture (EA) that results in harmony between IS / IT and the business needs of PT Ikido Jorr Indo Sepatu. In this study, the authors will design the EA using TOGAF (The Open Group Architecture Framework) with the ADM (Architecture Development Method) method. The results of this study are in the form of a enterprise architecture blueprint for the TOGAF method that is adapted to the business processes that are running at PT.

With the condition of a high level of need, the management of official manuscripts in the XYZ organization still uses conventional methods. So, this raises obstructed letter distribution and loss documents problem, and waste of paper use. We propose the Electronic Service Manuscript Management Application to replace the official script management process that previously applied conventional methods to using electronic methods to solve this problem. Besides, we also implement security aspects in the SHA-512 algorithm to fulfill authentication, AES-128 to meet confidentiality, and RSA2048 to meet integrity and non-repudiation. Apart from the security aspect, functionally, the system is built based on the Guidelines for Electronic Service Manuscripts, which are tailored to the organization's needs. The system development uses the Web Development Life Cycle (WDLC) methodology using the Yii2 framework. From the research results, it is concluded that the Electronic Service Manuscript Management Application has been built according to the needs of the organization and can be a security alternative in the official script management process. \u0000 \u0000Index Terms—digital signature; encryption; official script management; WDLC","PeriodicalId":309539,"journal":{"name":"Ultima InfoSys : Jurnal Ilmu Sistem Informasi","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123323180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data is processed in a short time, it will increase work efficiency, one of which is by using the system to process and display data into information. Information systems are needed considering technology is growing and now people are required to use more technology to reduce activities outside the home. Problems that often arise are the tight location of registration and the length of service for one registrant due to filling out registration forms and screening examinations for new students. In addition, the large accumulation of registration and trial files also takes a long time so that announcements of new student graduations cannot be made. The goal is to build a new student admission information system for all faculties at the Indonesian Methodist University, reduce applicants who come to the registration location, reduce the use of paper registration forms, help submit and fill in student data, conduct online screening exams, provide information on new student registration, schedule and payment of tuition fees.

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).
