Abstract

Sources of water pollution are usually derived from industrial or factories, homes, markets, rice fields, and hospital liquid waste. Water that contains detergent, feces and leftover foods that go into the drain daily can affect the balance of physics and chemistry of water. Residues that go into the sewer pipes can cause a blockage in the pipes. The objective of this study was to use a filtration bar screen grease trap to lower fat content, solids, and turbidity in domestic wastewater (dish-cleaning wastewater). The study is divided into two main stages which is the grease trap filtration bar screen assembly and the process for the grease trap. The grease trap works to catch leftover dirt and fats so that they do not block the pipes in the drain. Dish-cleaning sewage that has been processed in grease trap is not clogging up pipes in the sewer because the filtration process had separate solids and fats/oil. Fat content, solids, and turbidity is decreased after treatment. The modification of grease trap is possible so it does not only separate leftover food, fat or oil, but also purify wastewater by decreasing Total Suspended Solid (TSS).

Abstract

Apu-apu plants or commonly referred to as kiambang plants are a aquatic species that grow abundantly in wetlands. This abundance of aquatic plants can be used as a biofilter in addressing environmental problems particularly water pollution. This study is carried to test efficiency and fitoremidiation rate of apu-apu plants in lowering COD (Chemical Oxygen Demand) levels in gasoline contaminated water. A sample of apu-apu plant was taken from Karangkandri, Cilacap. After aclimatization, 15 apu-apu plant trees and 5 carp were placed in a container box that contained of contaminated water of 10 mL gasoline and then observed for pH, temperature and COD for six days. Temperature of contaminated water on 1st day is 28.5 oC and on 6th day is 27 oC. The value of the pH range of wastewater ranges is between 7.2-7.7. This suggests that wastewater is alkali mild. Phytoremediation ability of apu-apu plants in reducing COD levels has efficiency of 60%. This result indicates that the apu-apu plant is a good phytoremediator against contaminated water. The rate of phytoremediation or equal with COD decreasing at which apu-apu plants develop is 2.9 mg/L/day and goldfishes in contaminated water does not suffer death.

Abstract

Plastic is a polymer compound whose main constituent elements consist of carbon and hydrogen where one of the raw materials that is often used to make plastic is naphtha, which is a material produced from refining petroleum or natural gas (Surono, 2013). Chemical decomposition through a heating process without oxygen where the raw material will undergo a breakdown of the gas phase structure called pyrolysis (Jahiding et al., 2020). The quality comparison of pyrolisis oil, kerosene and oil, namely pyrolysis oil is lower than the quality of kerosene but higher than diesel oil based on density oil, duration of combustion, water temperature and volume of water that evaporates. Based on the research that has been done by Wahyudi (2018) and Mustam (2021) which is shown from the comparison chart of kerosene, pyrolysis oil and diesel oil based on the density of oil, duration of oil burning, temperature of cooked water and vaporized water volume. The quality of kerosene is better when compared to pyrolysis oil and diesel oil which is determined by the flash point of kerosene which is lower between pyrolysis oil and diesel oil, which is 47.8 oC. The flash point of diesel oil is 55 oC (the data on the flash point of kerosene and diesel oil were obtained from the Ministry of Energy and Mineral Resources in 2006). While the point of pyrolysis oil can be under the range of more than 47.8 oC and less than 55 oC. This is because the quality of pyrolysis oil is between kerosene and diesel oil.
