Rain is one of the water sources for life on the earth. The presence of rain becomes very important for the life of plants and animals because it will meet their need for water. In addition to the quantity of rainwater, its quality becomes an important role for life on the earth. Contaminated rainwater will result in decreased rainwater quality. This contamination can be physical, chemical and biological. Physical factors that can make rainwater quality worse is the value of acidity level (pH). Low value of acidity levels can lead to acid rain which is dangerous for plants, animals and even humans. This research focuses on rainwater quality seen from its acidity level. It can see how the impact of industrial pollution that developed in Cilacap to the quality of rainwater produced. The method used in this study used an analysis method based on SNI 06-2413-1991 with the rainwater samples from 15 places in Cilacap. The analysis obtained from 15 samples shows that rainwater in Cilacap district has pH 4.5 â 7.6. The rainwater pH <5 occurs in Trenggiling, Manunggal, Karangtalun, and Kutawaru.
