Batu Ampar Port is the largest loading and unloading port of the three existing loading and unloading port facilities in Batam and the largest port for manufactured goods used by companies to supply the industrial sector in Batam. In addition to having a positive impact, the Batu Ampar port also has a negative impact in the form of a decrease in environmental quality, especially the noise level generated by activities in the Batu Ampar Port area. In this study the noise sampling process used the Svantek tool, sampling was carried out for 24 hours with a time limit of 24 intervals, then sampling was carried out for 10 minutes at each time interval. The research results obtained were that from all sampling points the highest noise was in the East Pier area of 70 – 78.5 dB(A) at 08:00 – 23:00 WIB. While the area with the lowest noise level is in the BPJS flat area of 54.7 – 73.5 dB(A) at 06:00 – 05:00 WIB. It can be concluded that many of the noise values obtained exceed the quality standards in accordance with Kepmen LH No. 48 of 1996. This was due to several factors, namely loading and uploading of very dense containers which resulted in more and more work activities. Noise elimination measures in the Batu Ampar port area are important to do considering the results of noise measurements still exceed the quality standards, Barriers are one of the technologies that can be applied to reduce noise in the Batu Ampar port, Batam, both natural and artificial barriers, so the Batu Ampar port noise problem can be solved.

Mining activity is one of the producers of coarse particulates and fine particulates in the air which can have an impact on the surrounding environment. Limestone mining carried out by PT. Semen Padang is likely to contribute particulates such as Total Suspended Particulate (TSP) in the air. This study evaluates the dispersion pattern of TSP with variations in time and place to see its movement and direction of spread to determine affected areas or areas with high pollutants. Sampling and location determination refers to SNI 19-7119.6-2005 which consists of 30 observation points in 8 cardinal directions in the area around mining. Meteorological data was taken to see the dominant wind direction using the PCE-FWS 2.0 tool and then processed using the WR Plot software. TSP concentrations were measured using an EPAM 5000 tool which was divided into 4 shifts with the duration of each shift measured for 30 minutes, then TSP concentrations were mapped using Surfer 10 software. The results showed that TSP concentrations in the morning and afternoon were influenced by sampling distance and mining activity. , while the concentration of TSP at night is influenced by the wind direction and the sampling location. The TSP dispersion pattern in the morning and afternoon tends to be east, south, and west, while at night the dispersion pattern tends to be high in the southwest direction.

Increasing Green House Gases (GHG), including Carbon Dioxide (CO₂), have the potential to increase global temperatures, thereby causing climate change. Total CO₂ from human activities, for example transportation, electricity generation, industry, trade and agriculture, is expressed as a carbon footprint. Andalas University (Unand) has facilities that produce GHGs. This research aims to analyze the carbon footprint in Unand in the transportation sector. Samples were taken at the main gate (point 1) and back gate (point 2) Unand. For these two locations, the number of vehicles and fuel is calculated using the direct calculation method. The carbon footprint calculation refers to the Intergovernmental Panel on Climate Change (IPCC). The next step is to identify the potential for GHG reduction in Unand. The alternative GHG reduction observed is the absorption of CO₂ by vegetation. The research results show that the total carbon footprint on the Limau Manis Unand Campus is 2,221,020 kgCO₂eq/year from Point 1 and Point 2. The total CO₂ eq absorption capacity by vegetation on the Limau Manis Unand Campus is 9,297,557.51 kgCO₂ equivalent/year. When compared with the total CO₂ eq from transportation activities, the potential for reducing CO2 eq by vegetation is quite large. So, the Unand Campus road vegetation is still sufficient to reduce the 'contribution' of CO₂ eq from transportation activities in Unand to greenhouse gases. However, it is necessary to consider other possible sources of CO₂ besides transportation and the need to maintain existing vegetation

The eruption of Mount Marapi has caused damage to agricultural land and the temporary closure of Minangkabau International Airport. Simulations were conducted using HYSPLIT to detect the initial direction of volcanic ash dispersion. The trajectory analysis from HYSPLIT indicated that the volcanic ash dispersion on December 3, 2023, and January 5, 2024, extended beyond 100 km, while on December 22, 2023, January 19, February 4, and February 23, 2024, the dispersion was less than 100 km. HYSPLIT models indicated that the ash dispersion was directed towards Minangkabau Airport during the closure period. As a result, HYSPLIT can be considered a suitable software for simulating volcanic ash dispersion. Concentration evaluations based on Government Regulation No. 22 of 2022 revealed that several areas exceeded the applicable air quality standards. Validation using data from the HIMAWARI satellite and NASA WorldView indicated similar dispersion direction patterns in the simulation results. However, the Mann-Whitney test revealed significant differences when comparing the concentration outputs from HYSPLIT to PM2.5 levels before and during the eruption, based on PM2.5 monitoring documents from GAW Kototabang. Recommended mitigation measures include prioritizing the volcanic ash hazard zone within a 0-10 km radius from the crater by restricting activities and planning evacuation routes and safe areas away from volcanic ash exposure.
