Abstract

PT. Perkebunan Nusantara I Cot Girek is one of the palm oil mills owned by PT. Perkebunan Nusantara I which is engaged in processing palm oil into Crude Palm Oil and Palm Kernel Oil. The problem faced by PTPN I Cot Girek Unit is that there are several wasteful activities that cause the company to experience time losses, production does not reach targets and quality damage to Fresh Fruit Bunch (FFB) and Coconut Palm Oil (CPO). The problem solving method used are Value Stream Mapping to identify wasteful activities, the 5W1H method to identify the causes of waste and the Weighted Product Method to determine the order of priority for improvement. Based on the results of the study, there are 4 activities that can be taken corrective action. After being analyzed using VSM, it was found that the Manufacturing Lead Time decreased from 1185.70 minutes to 1069.73 minutes and the Process Cycle Efficiency value increased from 67% to 74%.

Abstract

One of the factors that requires more attention for the success of an industry is a smooth production process. PT XYZ is a company engaged in urea fertiliser and other chemical components. In its production process, the company needs steam as a primary resource, which is used both as a raw material for production and as an energy source. The problem the company faced during production is boiler downtime, resulting the lack of steam production generated. This study aims to calculate the boiler's effectiveness level using Overall Equipment Effectiveness (OEE) and to identify the risks of failure that occur in the boiler using Failure Mode and Effects Analysis (FMEA). Additionally, this study identifies the implementation of Total Productive Maintenance (TPM) within the company. Based on the OEE calculations, the boiler's effectiveness rate stands at 79.26%. These results indicate that the boiler's effectiveness has not met the international standards. The FMEA analysis reveals eight critical risks in the boiler, categorised as top priorities for maintenance. Improvements in OEE can be achieved by implementing one of the TPM pillars, which is preventive maintenance.

Abstract

This study investigates how Customer Relationship Management (CRM) strategies impact customer satisfaction and loyalty within the space rental service industry. Employing a quantitative approach through Structural Equation Modeling - Partial Least Squares (SEM-PLS), this study evaluates three CRM dimensions: people, process, and technology. The data were obtained via a structured questionnaire administered to 98 respondents and analyzed using the SmartPLS software. The findings reveal that process and technology significantly affect satisfaction and loyalty, whereas the people dimension has a minor impact. Specifically, the CRM process dimension positively influences satisfaction (t = 3.184, p < 0.01) and loyalty (t = 2.590, p < 0.05), while technology shows strong effects on both (satisfaction: t = 3.696; loyalty: t = 4.850; p < 0.001). The study recommends implementing operational CRM initiatives such as call centers, feedback mechanisms, and digital engagement strategies. This work contributes to the CRM literature by offering targeted insights for physical service businesses in Indonesia.
