Lampung is one of the provinces in Indonesia with an area of 34,623.85 km2 and has 15 districts/cities. Air pollution in Lampung Province has shown a significant increase, causing a decrease in air quality and environmental carrying capacity. This is based on the Lampung Province Regional Regulation Number 20 of 2014 concerning air pollution control. One of the most common inorganic air pollutants is sulfur dioxide (SO2). This study aims to determine the concentration of ambient air quality Sulfur dioxide (SO2) in the dry and rainy seasons and to compare the air quality in 15 districts in Lampung Province from the results of measurements using the Passive sampler method. Sampling was carried out in the rainy season (January) and dry season (August). The mean concentration was used as the annual mean value, and then data analysis was performed using a two-way ANOVA. Based on the two-way ANOVA test, the researchers found that the concentration of SO2 was not significantly different (p-value >α) between the average concentration of SO2 in each district/city for two consecutive years. This indicates that there is no difference in the average SO2 between the dry season and the rainy season, in other words that the dry and rainy seasons have no effect on SO2 pollutant levels.

Determination of the heavy metal content of Pb, Cd, and Mn in vannamei shrimp (Litopenaeus vannamei) in the waters of Labuhan Maringgai, East Lampung Regency. This research was conducted to determine the heavy metal contamination in the waters of Labuhan Maringgai, East Lampung Regency. Vannamei shrimp (Litopenaeus vannamei) was an aquatic biota that has the highest role in the absorption of heavy metals and had still commonly found in the waters of Labuhan Maringgai, so it was chosen as a bioindicator of heavy metal pollution. Shrimp sampling had been done by purposive random sampling method. Heavy metal analysis was carried out using Atomic Absorption Spectrophotometer (AAS) with wet digestion method which was carried out during sample preparation using HNO3 68% and H2O2 30%. The results of the analysis of metal concentrations of Pb, Cd and Mn in the vannamei shrimp samples, showed that the levels of Pb, Cd, and Mn metals had exceeded the safe limits set by BPOM RI No.5 of 2018.
