The Bengawan Solo is the longest river in the Indonesian archipelago, located on the island of Java. It crosses the slopes of Mount Lawu, crosses the province of Solo, flows over the plains and then flows into the Java Sea. Java is well known for having a tropical monsoon climate; therefore flooding is a common environmental problem throughout Indonesia. Java has a long humidity forecast from October to April, with the wettest months January and February. Due to the recent eruptions of Mount Merapi, Kelut and Lawu, there has been a distinct distribution of volcanic ash and remains carried by the waters of the Solo River. Volcanic ash contributes to the high agricultural fertility of farmland near the river. While it may be beneficial to the fertility of Solo's farmland, the ash brings illness and disease to those near the river. Furthermore, the floods affected people and their homes, making them habitable due to the access of water that entered their homes. The construction of the Wonogiri Dam was part of a major flood resistance strategy and hydroelectric power source for Solo, however annual floods continue to haunt the people of Solo. Annual floods have caused severe ecological, social and economic losses and damage. Local geologists predict that severe climate change will lead to better weather forecasts during rainy seasons, resulting in greater river overflows, severe flooding, landslides, casualties and losses. Due to the recent floods, which claimed over 100 lives, much of Solo's agriculture has been affected; buildings and transport were destroyed, thus causing great economic losses. Because of Solo's history with...half the card...even with use. Corruption is widespread in Indonesia. The organization may request a sum of money from the government to solve the flooding problem, although IFPP leaders may choose to pocket the money for their own use, instead of properly solving the flooding problem in Solo. Due to corruption, the remaining money may not be enough for construction, so they have to minimize the use of resources that could lead to a weakening of the dam, or they have to build a smaller dam that cannot decrease the levels of the dam. floods as well. Although problems such as corruption exist, the dam system would be an effective method because flood levels are controlled and hydrological energy could be provided to the population, thus slowly covering costs and resulting in a highly effective method. for the people of Solo.
