Abstract

PT Putra Chandra Sentosa is a company engaged in food and packaging machinery. In the business process that runs in the customer service division, the process of recording service submissions by customer service is carried out using word processing software which has the potential for data accumulation and the search for information on service submissions to be slower. Customer service has difficulty dividing technicians' duties due to service status updates that are not real-time, and they have to wait for technicians to submit a letter of assignment after the visit. In addition to using conventional data processing, customers who complain about service results or technician attitudes make management feel they need feedback reports regarding customer satisfaction. This study aims to design a website that is useful to facilitate the search for service information, perform a balanced division of technician tasks and assist management in seeing customer satisfaction in the form of reports. The Helpdesk Ticketing website in this study has been developed using Website Development Life Cycle (WDLC) model with the Hypertext Preprocessor (PHP) programming language, Unified Modeling Language (UML) notation and MySQL database. The PHP programming language is used in this research because various operating systems can run it via a browser. This research produces a Helpdesk Ticketing website that can answer the needs of the company PT Putra Chandra Sentosa. This research also proves that the website can optimize business processes in recording service submissions compared to using word processing software

Abstract

As an obligatory application during the COVID-19 pandemic by Indonesians, PeduliLindungi must have provided outstanding quality services to its users. However, as of December 2021, users’ sentiment toward the quality and service of the PeduliLindungi application was still low, with an application rating of 3.6 out of 5 on the Google Play Store. This study uses text mining techniques for the Aspect-Based Sentiment Analysis (ABSA) task in the PeduliLindungi application review, a sentiment analysis task based on the aspect category of the application. This study aims to classify the users’ sentiment on aspects of the application and provide insight and knowledge to improve the quality of the PeduliLindungi application. The ABSA method used in this study is the classification of aspects and sentiments using the Convolutional Neural Network (CNN) algorithm. The results showed that the CNN model could produce such good performance with an f1 score of 92.23% in the aspect classification and 95.13% in the sentiment classification. The results of user sentiment modelling showed the dominance of negative sentiment in the eight aspects of the application, namely Visual Experience, Scan – Check-in/Out, Vaccine Certificate, eHac, COVID Test, Register/Login, Performance and Stability, and Privacy, Data, and Security. Index Terms—Aspect-Based Sentiment Analysis, Convolution Neural Network, PeduliLindungi, Text Classification, Text Mining.

Abstract

PT Andalan Bunda Bijak is a company engaged in the distribution of baby equipment. In running its business, PT Andalan Bunda Bijak implements a system called MySoft to assist the company's business activities. The business development of the company has not fully run optimally. This is because there are still problems related to risk management (no SOP for handling problems, no division to handle problems, and no problem recording) and information security (no information security policy and no information security training). With this problem, it is necessary to measure the level of capability in corporate information technology governance. This study was conducted to analyze the level of corporate information technology governance capability using the COBIT 5 framework. This study uses 3 domains (EDM, APO, and DSS) and 4 processes (EDM03, APO12, APO13, and DSS05) obtained from the mapping results of PT Andalan Bunda Bijak's vision, mission, goals, and strategies for the problems faced by the company. Data was collected by interviewing the company's operational leaders and managers and observing the systems, documents, and company environment. The results of this study determined that each process was at level 1 (performed process). There is a gap of 1 level between the level of capability of the company's current state and the level of capability of the company's expectations. There are 28 recommendations for improvement given to the company.
