Abstract

Examinations in the school are still carried out conventionally, in a written method using a computer answer sheet. The development of a Computer Assisted Test (CAT) application website to replace the current exam implementation process is a problem for users who are not proficient in using computers. Users must understand new features and go through a long process of exam preparation stages. This research aims to design user experience, for the appearance of the Computer Assisted Test (CAT) application website, using the five planes framework. This method has elements that are done in stages from the lowest level to the top, starting from the strategy plane, scope plane, structure plane, skeleton plane, and surface plane. The result of this research is a user interface design prototype to be implemented on the CAT application website at a later time. The selection of the Five Planes framework with systematic stages is appropriate for designing user experience, starting from identifying the analysis of stakeholders business needs and objectives, directing the planning of a structured system function flow to create a website menu, to designing interfaces with attention to usability and aesthetics that are guided by design guidelines in selecting and displaying each visual element.

Abstract

Remo Dance is one of Indonesia’s traditional dance that originated from East Java and need to be preserved. The preservation act from collaboration of the Goventment and the Society started with a mass Remo Dance at Surabaya city on the year of 2022 that successfully granted a MURI record. This research is meant to support all the effort by calculating balance of the movements as one of the aspect of biomechanics. Biomechanics it self is a branch of study that learns about movement mechanism of living organism. The calculation of balance as an ability to keep a posistion on the change of movements is aim to analyze which movements has the most difficulty in balance and which one is the most stable from the chunk of motion capture data. Computation is done with high-level matrix/array language and the data form is a biovision hierarchy file (BVH). The Visualization of data shows that ‘ucek-ucek’ motion is the most stable movements, while 360 degree spin motion is a difficult movements and require great balance.

Abstract

Mitra Rakyat Wlingi Cooperative is still facing problems in managing customer data. The problem occurs because data management is split into two media, namely Microsoft Excel and books, which results in data duplication. Difficulties arise when searching for a list of customers who have made transactions or simply making monthly reports carried out by cooperative officers. This occurs due to unsynchronized data storage, which also affects the efficiency of service to customers. To overcome this problem, the author built an integrated system for cooperative officers in accordance with their roles in order to minimize data duplication and provide accurate information. The Research and Development (R&D) type research method uses the Systems Development Life Cycle (SDLC) which applies a development approach using a prototype model. The application was created using a website-based bootstrap framework. The application is tested using the black box method which focuses on evaluating and observing the input and output results of the application so that it suits user needs, so as to improve the quality of cooperative management and the image of service to customers.

Abstract

NoSQL Injection is one type of attack on the NoSQL Database management system (DBMS). This attack exploits a vulnerability that allows the attacker to send arbitrary requests to the server. If the server responds to an error query or an invalid query, the attacker will manipulate the query. The process of doing Blind NoSQL Injection is complicated. As a result, Pentester often takes a long time to be able to obtain information and penetrate the database server. Based on these problems, this research will provide a solution by developing a tool to automate Blind NoSQL Injection attacks. The results of this research indicate that the development of an exploit tool can enhance performance and efficiency. The binary search algorithm demonstrates a shorter runtime compared to linear search, making it a more effective choice. Additionally, the mitigation approach involving sanitization and validation of input for each key object has proven to be effective in preventing NoSQL Injection attacks.

Abstract

All business actors compete to find as many customers as possible and of course provide the best service, one of which is by considering the level of customer satisfaction. The aim of this research is to understand the level of customer satisfaction more effectively and provide valuable information for Jaya Fotocopy in making decisions to improve service quality in more detail. By grouping customer satisfaction into appropriate categories, customer management based on purchasing patterns, time of visit, and service received can identify areas that require improvement to ensure better customer satisfaction using the K-means algorithm. The results of this research classify customer satisfaction with dimensions of responsiveness of 76.32%, reliability of 91.10%, empathy of 90.11%, guarantee of 92.09%, and real evidence of 93.08%. Meanwhile, the specificity test of the K- Means algorithm method can classify customer dissatisfaction with the dimensions of responsiveness 27.17%, reliability 19.11%, empathy 19.00%, guarantee 19.50%, and real evidence 20.29%. From the results of the data obtained, Jaya Fotocopy must increase the dimension of responsiveness to only reach 27.17%. Jaya Photocopy needs to ensure that customer service is more responsive to customer needs and requests. This could include improvements in response times to customer questions or complaints and improving the ability to resolve customer issues quickly. Apart from that, Jaya Photocopy must also carry out further analysis to understand the causes of customer dissatisfaction in the dimensions of responsiveness, reliability, empathy, guarantees and concrete evidence. With a deeper understanding of the problem, more specific remedial steps can be taken. Jaya Photocopy can also improve communication with customers to hear their input and feedback regularly to find out what customers expect.
