The aviation sector in Indonesia, a vital sector of Indonesia's economic growth and national connectivity, faces challenges related to significant greenhouse gas emissions, particularly carbon dioxide (CO2). The Indonesian government, through the Ministry of Energy and Mineral Resources, has set a target to develop bioavtur with a 5% biofuel content by 2025. This regulation follows the international regulations of the International Civil Aviation Organization (ICAO) and the Environmental Protection Agency (EPA). These regulations set emission standards for pollutants such as particulate matter (PM) and nitrogen oxides (NOx) for aircraft engines. This research focuses on the design of an aircraft emission measurement system, based on the requirements and objectives of the regulations. Key questions involved identifying parameters and methods for measuring aircraft emission gases and evaluating the performance comparison of the current measurement system with existing regulations. The result of this study is the identification of important parameters for measuring aircraft exhaust emissions, namely smoke, hydrocarbons (HC), carbon monoxide (CO), nitrogen oxides (NOx), non-volatile particulate matter mass (nvPM mass), and non-volatile particulate matter number (nvPM number). The six parameters are measured using 3 different test methods. These methods are smoke testing to measure smoke emissions, gas emissions testing to measure HC, CO, and NOx, and nvPM testing to measure nvPM mass and nvPM number. Based on the review, only 2 of the 3 recommended testing methods are gas emission testing and nvPM testing. The recommended measurement system for gas emission testing is the MEXA-1700 because it uses three different methods depending on the gas emissions being measured. The recommended measurement systems for nvPM testing are AVL Micro Soot Sensor 2, AVL CPC and CPC 3750-10 due to their compliance with regulations. For now, it is necessary to search for data on these measurement systems to ensure that the measurement tools can be used for aircraft exhaust emission testing.
