The high market demand for coffee products made from robusta coffee requires PT Tinkerbels Permata Indah to produce more coffee continuously in an effective and efficient, therefore companies need to measure productivity to determine the performance of using several inputs to produce output. The purpose of this research is to analyze the level of productivity of robusta coffee bean production and to make a proposed improvement plan for PT Tinkerbels Permata Indah. The method used to measure productivity in this study is the objective matrix (OMAX) method. The weight of each criterion was obtained with the help of the pairwise comparison method by filling out a questionnaire by the three experts involved. Based on the research results, the company^s highest productivity achievement was 5.893 in April 2022 and the lowest was in September 2022 with a current value of 0.880. Proposed improvements include companies needing to pay attention to their warehouses by maintaining temperature and humidity so that materials are not damaged by warehouse pests, implementing flexible daily hours to reduce wastage of employee work time, implementing an energy-saving culture and conducting energy audits, and implementing maintenance management at the machine.
