Abstract: The Dinoyo road is a connecting road and the entrance of Malang city from the north side starts from Soekarno-Hatta roads, then becomes the entry point to the tourist area of Batu City and several campuses. The volume of vehicles on the Dinoyo road often experiences a significant increase. The types of activities in the Dinoyo road area are very diverse, making the intensity of traffic movements on this road to be high and potentially lead to traffic congestion. Increasing the number of movements using motorized vehicles can cause congestion and can reduce environmental quality and cause impacts, one of which is noise. Measurements are made to determine Ls, that is, certain values of noise change. (fluctuations during a certain time, which is equivalent to the noise level of steady noise at the same time interval) in units of dB. The measurement procedure is carried out by taking two times (morning and evening time). Each measurement time is carried out at 3 points with 5 times replication of data every 15 minutes. The results of the measurement value at the highest morning time division are 95.5 dB (triple road section on the fourth measurement) and the lowest is 82.2 dB (one road on the first measurement). Furthermore, the classification of the measurement value at the highest afternoon time division is 100 dB (road two on the third measurement) and the lowest is 81.7 dB (road three on the first measurement). Efforts that can be made by the community to reduce noise include the use of earplugs or sound absorbers installed in stores or homes, as well as controlling at the source, and receiving the sound so that unwanted things do not occur.
