The BKAD Regional Asset Sub-sector in Banyumas Regency has a type of Goods Inventory Card (KIB) that has not been managed properly, including KIB for office vehicles making it difficult to make a proposal for office vehicle maintenance. Maintenance of office vehicles is the initial stage of replacing vehicles according to employee needs so that employee performance can be maximized. Forecasts for office vehicle maintenance are presented to facilitate the implementation of duties in carrying out business trips. The methods used in data collection are survey methods, literature, and interviews. The data collection method used in this report uses a quantitative method with the C.45 algorithm. Predicting the quality of office vehicles can carry out several stages such as reviewing office vehicles, classifying the condition of office vehicles, after that a decision is made on which vehicles are suitable for use or not suitable for use. Analysis of predicting the quality of office vehicles using the C.45 algorithm with the rapidminer application can produce results in the form of a decision tree that is used by the asset sub-sector in order to make a decision. Based on the prediction results of office vehicle quality, it can be concluded that office vehicles will be suitable for use if the year of purchase or procurement is more than 2000 and office vehicles will not be suitable for use if the year of purchase or procurement is less than or equal to 2000. If you want to compare the results obtained it is advisable to use other tools or algorithms to make the next report.","PeriodicalId":233506,"journal":{"name":"Journal of Information System Research (JOSH)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134270378","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}

WeTV is an online streaming that is used by the public as a medium of entertainment. The WeTV application has a rating of 4 out of 256 thousand reviews written by its users. The collection of reviews in the form of text can be collected and classified into negative responses, neutral responses, and negative responses. Positive responses are comments that are optimistic or supportive. Negative responses are comments on phrases or cases that do not support statements about related cases. Neutral responses are comments that are difficult to understand between negative or positive in nature to provide suggestions, sentences that have reviews from application users can be positive, negative and neutral, the data will go through a classification process using the K-Nearst Neighbor method. In this study, 12,000 reviews were used from the playstore. The research used the preprocessing stage, namely cleaning, case folding, tokenizing, normalization, stopword removal and steaming then to the TF-IDF stage and the final results will be tested with a confusion matrix using the Python programming language.

This company provides services and services related to waste transportation, waste recycling, as well as waste management education and consultation. These services can be accessed online through the website owned by Waste4Change. Based on the website, there are several programs and features that can be used by users, one of which is the Send Your Waste program. However, in the program, there is a waste delivery flow which has drawbacks, namely flow mismatch and copywriting on the Send Your Waste page. Therefore, this study aims to improve and develop the waste delivery flow in the Send Your Waste program to make it more user-friendly for users. The research method used is the design thinking method to find out what are the complaints and needs of users regarding the experience and appearance of the website interface. This method was chosen because it can solve complex problems with empathy to understand the needs and motivations of users and there is also an iterative process in order to find the best design solution.

The authentication process in applications and the web is used to identify ownership of user data, this is because there is a vulnerability to attacks in the use of unsafe usernames and passwords. There are several security issues, one of the most common being passwords. Most systems use passwords to verify user identity. However, these passwords come with major security issues as users tend to use ones that are easy to guess, use the same password across multiple accounts, write it down and store it on their devices. Hackers have many options using which to steal passwords or hack user accounts such as credential stuffing, phishing, password.spraying, bruce force, prior data breach / reused passwords, password reset, keystroke logging and local discovery. To overcome security attacks, Multi-Factor Authentication (MFA) techniques provide higher security guarantees.
