is easy to implement, easy to understand, and flexible so that it can be adapted to the company's conditions and needs [5], [6]. The OMAX method can provide an overview of how effective the production process is and how efficient the utilization of resources is by the company [7].
production capability of a company. XYZ Company is one of the producers of Balinese robusta coffee powder that has been established for more than 50 years. Nowadays the company has problems meeting the increasing market demand. This study aims to measure and analyze the company's productivity using productivity indicators that are considered important by experts so that they can be used as a benchmark for improving productivity in the company's production department. The objective matrix (OMAX) method is used to measure productivity helped with analytical hierarchy process (AHP) as tools to weighting the productivity indicators and Fault Tree Analysis (FTA) method to analysis the roots of productivity problem. Based on analysis using Trafict Light System (TLS) method, the company's productivity index in 2023 was categorized as low with an average score of 3,105 that caused by the low performance of all five productivity indicators. These indicators are the main factors contributing to the low company productivity index, with a total potential increase in the productivity index of 222.08%. The problems that cause the company's low productivity value are roasting machine downtime and the number of days of leave taken by production staff. To significantly increase productivity, the company is recommended to replace the current machine with a modern one, provide training for production staff, and utilize information technology (IT). Key Words: fault tree analysis, productivity, robusta coffee.
objective
XYZ Company is one of the producers of powdered robusta coffee in Bali Province that has been established for more than 50 years. The company has experienced difficulties where the increasing level of market demand has become difficult for the company to meet. According to [1], if a company experiences high profitability but is not balanced with high productivity, the company will not be able to maintain that level of profitability in the long term because low productivity can erode the company's profits. To determine the factors that affect productivity, productivity measurement can be carried out using the Objective Matrix (OMAX) method. In the OMAX method, a method is needed to determine the weight of each productivity indicator. The Analytical Hierarchy Process (AHP) method is used in this weighting to prevent misinterpretation of the importance of each indicator. Indicators that show the accumulation of the worst performance figures are analyzed using the fault tree analysis (FTA) method to find the root of the problem. Measuring the productivity index at XYZ Company has several objectives. The objectives of this study are to determine the value of the productivity index of XYZ Company, to identify the factors that most influence the low performance value of the production department of XYZ Company, and to provide recommendations for improvements that XYZ Company must make to improve the productivity of its production department.

I. INTRODUCTION Productivity is a value used to measure the performance of individuals, organizations, and companies [1]. Therefore, productivity is a crucial factor in determining the sustainability of a company in the future. It involves the utilization of resources (inputs) as efficiently as possible to produce or increase outputs in the form of goods and services effectively [2], [3].A company's productivity needs to be measured periodically to determine whether the company's performance level has met the established targets or standards[4]. One method that can be used to measure productivity is the objective matrix (OMAX) method. The objective matrix method is a partial productivity measurement method that

II. LITERATURE RIVIEW 2.1. Productivity Productivity is a value assigned to the production capacity of an individual, organization, or company [1]. [8] states that productivity is defined as the result obtained from each production process that uses one or more production factors. Productivity is usually calculated as an index or ratio of output to input and can be expressed in physical and financial measures. A similar opinion was
