Waste in Sorong consists of a mixture of organic and non-organic materials. Based on its categories, Sorong's waste can be classified as plastic, paper/cardboard, glass/bottle, iron/tin, hazardous waste (B3), and organic waste. The purpose of this community empowerment activity is to maintain the beauty of the public space panorama and instill discipline in the disposal of waste among all residents of Sorong. This community engagement activity took place on September 13, 2023, in front of DEO Airport in Sorong City, Southwest Papua Province. The community engagement activities included: (1) Delivering a presentation on the importance of World Cleanup Day; (2) Cleaning up waste around the public areas of DEO Airport; and (3) Collecting waste in bags for weighing. The theme for this activity was "Environmental Cleanup Service in Sorong City in Commemoration of World Clean Up Day 2023." The technical approach for World Cleanup Day this year involved dividing groups into "A, B, G, C" (academics, business, government, and community) within designated "work focus areas" (waste cleanup) spread throughout the DEO Airport area in Sorong City, particularly in public spaces that are central points for waste input. Therefore, the recommendation from this activity emphasizes the importance of avoiding the use of plastic in daily activities that tend to rely on plastic.

Most residents in Kilo 10, Sorong City, use well water for daily needs. One common issue is the presence of iron in the well water, which causes rust and brown stains on clothes or household items. This study aims to determine the pH, TDS (Total Dissolved Solids), salinity, conductivity, turbidity, TSS (Total Suspended Solids), and temperature in well water. The well water samples were taken from areas with neutral pH (Sumbersari), basic pH (Puger), and acidic pH (Kencong). The results showed that the pH of the well water samples was 6.2, TDS was 185, indicating that the well water met the standards. The salinity was 150 or 1.5 mg/L, and the conductivity of pure water ranged from 0-200 Î¼S/cm (low conductivity), large river water ranged from 200-1000 Î¼S/cm (mid-range conductivity), and saline water was 1000-10000 Î¼S/cm (high conductivity). The conductivity value for potable water is around 42-500 Î¼S/cm. The turbidity result was 19 NTU, indicating that the well water sample was not suitable for drinking. The TDS value was high at 667, and the temperature was 30.5Â°C.

The purpose of this research is to evaluate the condition of existing drainage channels in the area around Jalan Pulau Batanta Kompleks. In addition, it is also to determine the capacity of existing drainage channels to rainfall with a 2-year, 5-year and 10-year plan discharge. Rainfall frequency distribution analysis is carried out using the distribution analysis method, namely the Normal Distribution Method with chi-square calculations and Kolmogorov Smirnov suitability test. Rainfall intensity is calculated using the Mononobe equation and modeling with EPA-SWMM by simulating the drainage network and calculating the flood inundation area. The existing condition of the drainage system in the complex area along Jalan Batanta Island in accommodating the maximum rainfall discharge is still often overflowing, this is obtained from the results of the EPA-SWMM analysis that the channels around Jalan R.A. Kartini overflowed the most in the return periods of 2 years, 5 years, and 10 years with the largest runoff in channel 15. From the results of the evaluation of drainage channels and networks, it is known that the cause of flooding in the area around Jalan Batanta Island Complex is the existence of drainage channels that should accommodate rainwater, due to the large amount of sedimentation, as well as garbage that reduces the capacity of other channels. All channels reviewed have a sub-drainage area of 3.18 Ha with a total length of 7544.33 meters in good condition.

Organic waste is the most common in the Muhammadiyah University of Sorong's (UNAMIN) environment. The presence of organic waste can cause unpleasant odors, reduce the aesthetic value of the campus environment, and cause disease. Eco enzyme is a waste fermentation process in the form of fruit peels and vegetable remains. Eco-enzymes are widely used in household, agricultural, and fishing activities. One alternative to reducing organic waste in the UNAMIN campus environment is introducing and making Eco-enzymes from fruit waste. This community service activity aims to increase the knowledge and skills of the UNAMIN campus community, especially in the environmental engineering study program regarding making Eco enzymes from orange peel. This activity is specifically for environmental engineering students, hoping that ecological engineering study program students will provide an example for other study programs within the Mumahhadiyah University of Sorong. Until now, we have not handled wet organic waste in the campus environment. Eco enzyme can be an alternative use of wet (organic) waste that is environmentally friendly and easy for the campus community to use. The results of this Eco enzyme can be used as liquid fertilizer for gardens on the UNAMIN campus. The organic waste processed into enzymes is obtained from the campus canteen. Apart from being used as liquid fertilizer, this Eco enzyme is also used to clean fish ponds at the fisheries faculty.
