Abstract

In today's internet age along with the advancement of web technology and its growth, large amounts of data today can be used and utilized to analyze and win the market. Social networking sites such as Twitter are quickly able to get neutral, positive and negative customer opinions and discussions using sentiment analysis methods. In this study the process of classifying sentiments using the Naïve Bayes Classifier method. This method approach provides digital-based surveys and comparative analysis such as machine learning and lexicon-based approaches. The results obtained from research based on data mining surveys there are five main complaints that are the main focus of telecommunications service companies, namely network, convenience, price, internet and services. Sentiment analysis based on test results showed the highest polarity of opinion was in the network at 60.07% and the lowest comfort with a value of 36.63%. The higher the polarity value, the higher the company's chances of making further improvements. The results showed that the development of big data mining systems helped companies to more accurately and effectively meet customer needs and classify sentiment towards products that have been launched.

Abstract

PT XYZ is one of the companies in the snack food industry that focuses on processing biscuits. There is still waste in the production process, such as waiting and transportation, which adds time to the production process and makes it longer. To reduce waste and improve business efficiency, this research uses lean methodology and value stream mapping to ensure the biscuit processing production process runs smoothly. The results of the research that has been done, there is a decrease in non-value-added time by 13.27 minutes from 22.77 minutes, a total lead time of 68.32 minutes from 77.82 minutes, and process cycle efficiency increased by 75.29% from 66.10%. This shows that implementing lean methods using value stream mapping can improve the company's efficiency and productivity.

Abstract

Multi-project management are a huge challenge in organizations project management. In order to improve the success of multi-project practice, organizations are begun to considering to implement Project Management Office (PMO) inside their organization structure as a single structure that focused on managing project portfolio inside organization. PMO is a type of business-oriented organizational structure that supports the enterprises business strategy, development and describes the rationale of how a project-portfolio management organization shold be. The major challenge in this qualitative research is to identify which variables that proposed PMO department have to take concern of and formulize a relevant PMO model, scope and project management process to its organization. Literature reviews enrich that the ideal PMO should have able to integrate organizations project portfolio, standardize project management methods, providing tools, managing continuous improvement and designing effective communication system. As results, proposed PMO department will be adopting controlling model, have strategic, tactic and operation scope with their own maturity level based on PMO maturity cube and a new proposed project management process, involving entire stakeholders within project environment.

Abstract

The Vehicle Routing Problem (VRP) is one of the basic combinatorial optimization problems that takes a central place in the sphere of logistics, transportation, and supply-chain management. A systematic literature review (SLR) of VRP scholarship dated 2000 to 2025 is conducted herein, where over 500,000 publications are analyzed to carry out the study of VRP solutions evolution and methodological advancements as well as their practical use. The results highlight the current popularity of metaheuristic algorithms, such as Ant Colony Optimization (ACO), Genetic Algorithms (GA), and Particle Swarm Optimization (PSO), in solving complex variants of VRP, in particular, the Capacitated Vehicle Routing Problem (CVRP) and the Vehicle Routing Problem with Time Windows (VRPTW). The combination of real-time data streams, machine-learning methods and adaptive algorithms represents a revolutionary track, and helps to develop more active and responsive VRP models. Moreover, increased attention to sustainability and green logistics has triggered the development of the eco-efficient VRP models, which combine the use of electric vehicles (EVs) and energy-consumption optimization. The spread of autonomous vehicles presents new opportunities and threats to future VRP solutions, particularly in the area of urban freight and last-mile delivery. In conclusion, the review outlines future streams of research, highlighting the need to find adaptive, sustainable, and autonomous VRP models that can resolve the growing complexities in the modern world of logistics.
