This research aims to determine the performance of the Diesel Particulate Filter (DPF) in reducing exhaust gas opacity, smoke temperature, and noise levels on the 1997 Isuzu Panther. The DPF used in this research is composed of copper and stainless steel, featuring a metallic honeycomb design. This experimental study involved installing a DPF on a standard diesel vehicle exhaust system and measuring exhaust emissions, smoke temperature, and noise levels. The measuring instrument used to test the opacity and temperature of the exhaust gas is a smoke opacity meter based on the SAE-J1667 test procedure (snap acceleration test procedure). Meanwhile, to test the noise level, a sound level meter based on ISO/FDIS 5130:2006 (E) standard was used. Tests were carried out under various conditions, including standard exhaust testing (Non-DPF), standard exhaust with DPF (DPF), DPF with 50 gram stainless steel material (DPF SS50), DPF with 100 gram stainless steel material (DPF SS100), and DPF made of 150 gram stainless steel (DPF SS150). The test results showed that DPF had a significant effect on reducing exhaust opacity, smoke temperature, and noise level of the 1997 Isuzu Panther. The greatest reduction in exhaust opacity, smoke temperature, and noise level was produced by DPF 150 gram stainless steel, with exhaust opacity that could be reduced by 87 1 ± 1.1%, smoke temperature of 43.2 ± 1.7%, and noise level of 15.2 ± 1.3%. These findings open up opportunities for the development of DPF technology that is more efficient in reducing diesel vehicle emissions, contribute to stricter emissions regulations, and support filter design innovation to improve air quality and reduce the negative impact of vehicles on the environment. In addition, the results of this research show that the use of DPF is in accordance with the diesel vehicle emission threshold regulations set in Indonesia.

The research demonstrates that the DPF significantly reduces exhaust opacity, smoke temperature, and noise levels in the 1997 Isuzu Panther.The greatest reduction was achieved with the DPF incorporating 150 grams of stainless steel, lowering opacity by 87.These findings support the development of more efficient DPF technology, stricter emission regulations, and innovative filter designs to improve air quality and minimize the environmental impact of vehicles.

Further research should focus on optimizing DPF materials beyond copper and stainless steel to enhance filtration efficiency and durability. Investigating the long-term performance and regeneration characteristics of DPFs under real-world driving conditions is crucial for assessing their lifespan and reliability. Additionally, exploring the integration of DPF technology with other emission control systems, such as selective catalytic reduction (SCR), could lead to synergistic effects in reducing overall vehicle emissions and improving air quality. These studies should also consider the economic feasibility and scalability of implementing advanced DPF technologies in various vehicle types and emission standards, ultimately contributing to a more sustainable transportation sector and public health benefits.
