In the water works many problems can not be solved with available formulas. This is because the equations were derived from a certain condition that is not necessarily the same situation with the conditions of the planned the water works. Therefore, the hydraulic modeling is very useful. PLTGU Cilegon has several problems, among others: 1. in the event of high sea waves in the Java Sea, the sea water entering through the in take and can cause damage to the blade mixer behind the trash rack; 2. Trash and sediment sucked into thein take until the base so that it can inter fere with the performance of the cooling system. To overcome these problems several alternatives proposed by the pond wave absorbers.The first alternative (addressing sediment and litter) is performed with an entrance aperture variations to determine the water leveland wave in the channel. The second alternative is to be made baffles channel, where the channel baffles makes natural variation door openings. The third alternative is to regulate the water level and wave into the channel by increasing the dimensions of the channel.The results of the simulation in the laboratory, baffle channel before the in take tract with the door dimensional variation sand water level setting and the waves can be used so that thein take tract waves, sediment and trash can be overcome.Keyword: hydraulic modelling,PLTGU Cilegon, the channelbaffles

One of the biggest environmental issues today is plastic waste. This waste cannot be avoided and continues to increase which in its decomposition takes 50-100 years and will be fragmented into smaller forms called microplastics. Microplastic measuring < 5 mm with various shapes. The people of the Nipah Panjang area dispose of plastic waste into the Batanghari River which is likely to cause microplastic content. To determine the number of microplastics, it is necessary to identify the abundance of microplastics found in the Nipah Panjang area on the Batanghari River using quantitative methods. The tool used is Planktonet mesh 150 with a diameter of 20 cm. The sampling process was carried out for one day with two samplings, namely in the morning at low tide at 09.00-11.00 WIB and in the afternoon at high tide at 15.00 WIB. The study's results were sampling in the morning at low tide with 327 microplastic particles and the highest in the afternoon at high tide, namely 443 microplastic particles. The temperature in the morning and evening ranges from 29°C - 32°C. The results showed that four types of microplastics were found, namely the type of fiber, filament, fragment, and granule. From the four locations of Sungai Air samples, the most microplastic fragments were found with a total of 353 particles, the second most were filament types with a capacity of 191 particles, the third type of fiber with a total of 186 particles, and the least types of granules with a total of 40 particles. Microplastic at low tide is lower than at high tide. The abundance of microplastics from the four sampling locations of river water is 25,666.67 particles/m3.

The need for clean water is currently the concern of many people, especially brackish water that occurs from land water discharge and the mixing of sea water with fresh water. Jambi Province in particular, there are several areas downstream of the river where the chemical/physical properties of water are blackish brown and are brackish water content, with this water content it is necessary to find a way to reduce the level in order to get water that is suitable for use by the community. The purpose of this study was to separate the content of brackish water using the plasma DBD (Dielectric Barrier Dicharge) method. Where the plasma concentration of DHF affects the level of brackish water related to Ph, TDS and Salinity. From the results of research on the DHF Plasma process for purification / separation of parameters of brackish water content from parameters of Ph, TDS and Salinity, there is a change or decrease in each of these parameters at each change in the length of the test time (5 minutes, 10 minutes and 15 minutes).
