Abstract

Service is one of the important factors that need to be considered for the Industry, Bandung Konveksi is a company that provides various uniforms, such as for schools and offices. The company has experienced a decline in customers and revenue every year due to dissatisfaction with services. This study aims to identify service variables that are less important and need improvement, and to develop improvement proposals based on priorities. The methods used are Service Quality and Quality Function Deployment. The research begins by determining the variables of customer needs, followed by determining the level of customer satisfaction. Then, determine the priority of service quality improvement and end with the preparation of service improvement proposals. The results showed a negative GAP of -2.17 on average, indicating customer dissatisfaction. Importance performance analysis identified 7 important variables that need to be improved. Quality Function Deployment determined 6 improvement priorities: providing training to employees, implementing structured handling procedures using customer relationship management (CRM), improving communication efficiency by utilizing chatbots, optimizing detailed production schedules, being polite and courteous, and establishing procedures for handling the change process.

Abstract

The increasing generation of municipal solid waste (MSW) in Pekanbaru, a densely populated city in Riau Province, has led to higher waste management costs. In 2023, the city generated 1,011 tons of waste daily, with management costs reaching around IDR 93 billion. Traditional cost calculation methods are often inaccurate, failing to account for the activities involved in MSW management. This study develops an activity-based cost management model using Activity-Based Costing/Management (ABC/M) to map costs to specific waste management activities, combined with Causal Loop Diagrams (CLD) to analyze activity relationships and formulate a mathematical cost model. The application of ABC/M identified four primary waste management activities: collection, transportation, processing, and disposal. The results show a total waste management cost of approximately IDR 91 billion, with CLD revealing dynamics such as the impact of incentives on recycling rates and the balancing effects of transportation and waste bank usage on waste generation. This study contributes provides a novel cost model for municipal waste management, offering both theoretical and practical contributions for improving cost efficiency and resource allocation.
