Abstract

This Paper Company is a manufacturing company at the field of thin paper industry. At the beginning, this company did not have the quality assurance to final product which has the standard of the quality management system. This study represents that the company doesn't have the Quality Plan to the product. The Quality Plan become the main concern to assure the product quality until they are distributed to the customer. This study is meant to design the Quality Plan for the company management system. It will be divided into three parts; first, the inspection of the raw and chemical materials, second, the inspection of the production process, and the final is the inspection of the output jumbo roll. This first inspection is done five times, the second inspection will done in twelve times, and the final process will be done in one process only.

Abstract

The problem faced by company is the difference in PPIC Department between actual result and planned result. The second problem is the low efficiency in bush forming and pin cutting area. Related to that problem, company asked to researcher to do a research on current total workers composition whether it's suitable or not. The method used in this research is standard work combination sheet. The current total workers in bush forming and pin cutting area is proper enough, each area with one operator and one supporter to help both area. The first improvement to do is to divide the task and to shift the role between operator and supporter. Workers with high ability work as supporter to fix machines and workers with moderate ability work as operator. The second improvement is to revise work motion for bush forming and pin cutting operator to be more efficient in movement and time.

Abstract

The article discusses the measurement model of tourism destination images perceived by travellers based on five dimensions of the service quality, i.e. tangibles, reliability, responsiveness, empathy, and assurance. Measurement problems occur when a traveller assesses the quality of a tourism destination service subjectively with vague boundaries and perceives the image of a tourism destination to vary. To address these issues, we designed an inference model using Mamdani's fuzzy inference system. The results of this study are quantitative assessments of the image of tourism destinations by various travellers based on qualitative perceptions of the quality of service experienced by the traveller.

Abstract

This paper develops a principal–agent model for ISO 9001:2015 quality audit in a manufacturing company, where the auditee is an informed agent and the auditor is a principal who designs an incentive-compatible audit mechanism. The proposed mechanism combines self-reported performance, risk-based audit probabilities, and quadratic penalties on deviations between reported and verified performance. We establish explicit mathematical conditions for incentive compatibility and individual rationality that guarantee truthful reporting and substantive compliance as the optimal strategy for the auditee. The mechanism is shown to be constrained Pareto optimal within a natural class of audit contracts: no alternative contract can increase the auditor’s expected utility without reducing the agent’s utility, given the informational constraints. We prove the uniqueness of this optimal solution given a maximum feasible penalty. A parametric sensitivity analysis and a case study from the Indonesian manufacturing sector illustrate how the choice of audit probability, certification benefit, and penalty parameter can transform a symbolic certification regime into an equilibrium with genuine quality improvement and credible ISO 9001 implementation

Abstract

The Free Nutritious Meal Program (MBG) involves a tiered flow of funds from the National Nutrition Agency (BGN) to foundations that contract local catering partners. In practice, two recurrent problems emerge: partial diversion of program funds and delays in payments to caterers. These issues threaten service quality and the financial sustainability of small catering providers. This paper develops a mathematical model that combines principal–agent theory and goal programming to support policy design for BGN. The foundation’s utility captures legal margin, potential diversion, and expected monetary penalties that depend on audit intensity and audit effectiveness. The principal (BGN) pursues three goals simultaneously: minimizing total diverted funds, minimizing weighted payment delays, and limiting total audit cost. Individual rationality (IR) and incentive compatibility (IC) constraints are incorporated to ensure foundations are willing to participate and prefer honest behavior. The resulting nonlinear goal programming formulation provides a structured way to explore trade-offs and to select audit and penalty parameters consistent with MBG objectives. A small numerical illustration demonstrates how the model operates and how policy parameters influence outcomes.
