Then in evaluating the website the author also uses an additional method in the form of System Usability Scale (SUS). System Usability Scale (SUS). The solution design evaluation stage is almost the same as the initial design evaluation, namely measuring usability which includes three aspects of effectiveness, efficiency and user satisfaction. The respondents who participated in this assessment are the same respondents who participated in designing the initial design assessment. The researcher's observations showed that overall all the respondents successfully completed the task. This can be seen from the calculation of the percentage of effectiveness obtained by 100%. In the aspect of efficiency, the average time required for working on the task. Information related to the tasks assigned is the fastest at 3.26 seconds. This aspect of user satisfaction uses a System Usability Scale (SUS) questionnaire. The respondents involved in the design of this solution were still the same as at the time of the initial design, which used 10 respondents consisting of 3 stakeholders and 7 internship children from PT.

Abstract

Baraya Cargo is a shipping company that carries out shipping activities through a series of business process activities starting from contract agreements, shipping preparation, delivery, and ending with the issuance of invoices. The current business processes are still experiencing problems from time delays and the occurrence of a lack of documents that disrupt the performance of Baraya Cargo. Therefore, improvement activities were carried out starting from modeling the main business processes in the form of Business Process Model and Notation (BPMN) in the Bizagi application. The business process model is then evaluated using the Quality Evaluation Framework (QEF). It was found that there are 3 main business processes that have problems where there are inappropriate metric values. After that, an analysis was carried out using Root Cause Analysis (RCA) to find the root cause of the metrics that did not match. Recommendations are then given using streaming tools from Business Process Improvement (BPI). Finally, a simulation was carried out through the Bizagi application to determine the time performance improvement between business processes (as-is) and business processes (to-be). The simulation results show that the contract agreement business process has increased performance by 75.5%, the delivery business process is 1.6% and the invoice issuance business process is 76.5%. It can be seen that the implementation of the recommended business process shows a significant performance improvement when applied to Baraya Cargo.

Abstract

Vinokost is one of the boarding houses in Malang City. This boarding house is close to various well-known university in Malang City. The existing management or administrative system at Vinokost uses simple recording on books and receipts for payment. Payments made by boarding house residents are also still in cash. The occupants or renters of the boarding house must go to the automated teller machine to withdraw the money which will then be paid to the boarding house manager. This process certainly does not take a short time. Therefore, a web-based information system is needed to facilitate the management of boarding houses and is also integrated into the payment gateway to facilitate payments. The Vinokost boarding house management system was built by adapting the Waterfall development method. There are 5 stages, namely data mining, requirements analysis, system design, implementation, and testing. The boarding house management system is developed using the Laravel framework for the backend and Bootstrap for the frontend. The database used is MySQL with the help of phpMyAdmin. As for the payment gateway using services from Midtrans. In the tests carried out using Black Box Testing, the status of 100% successful means that the requirements that must be met by the system have been met.

Abstract

In the process of daily activities at Perum Bulog, the Malang branch office still uses the conventional method, namely, marketing to consumers using paper leaflets that are distributed or given directly to consumers by the BULOG commercial division. And consumers who want to join as RPK (official BULOG distributor) must come and register directly at the Malang branch of BULOG. To overcome this, an online information system is needed in order to organize marketing management properly. Utilization of internet technology in the marketing efforts of a company's products is one solution in increasing sales and income in the business world. To overcome the barriers of space and time that have been obstacles to conventional sales systems, this cannot be separated from the role of the web as a source of information on the internet. The implementation of the development of the BULOG Product Catalog Information System uses one of the SDLC (System Development Life Cycle) methods, namely the Waterfall Model. The Waterfall model was chosen by the author over other models because the author feels that this model is the most effective and suitable model to help solve this problem. Development using the Waterfall model is carried out in stages and a detailed definition of each phase is carried out, especially in the system requirements planning phase at the beginning of the application process. Furthermore, in this development the author uses the CodeIgniter Framework, because the CodeIgniter framework is relatively easy to understand and CodeIgniter also provides various kinds of libraries that can facilitate application development.

Abstract

Warung Wareg is a restaurant that serves a home-cooked menu with a mainstay menu in the form of various processed fish-based ingredients. In its business activities, restaurants need to carry out customer relationship management, one of which is by managing feedback well. One way that can be done is to manage reviews from users. The number of reviews numbering in the thousands makes it difficult for Warung Wareg to manage customer reviews, therefore a sentiment analysis is necessary to find out what customers think about Warung Wareg's services and products. The source of review data comes from Google Reviews and Tripadvisor by utilizing selenium for web scraping. Sentiment analysis was performed using the Support Vector Machine (SVM) method with term frequency - inverse document frequency (TF-IDF) as word weighting. Random undersampling technique is used to handle imbalance dataset. Hyperparameter tuning technique is done to produce the best model. Testing the results using the confusion matrix produces an accuracy value of 94%. The dashboard page is used to visualize the classification results using the Google Data Studio platform. The negative review ranking process is carried out to find the most negative reviews given by customers. From the results of the classification, a root cause analysis is also carried out to find the root causes of the negative reviews to formulate business recommendations that can be taken to overcome these problems.
