Fish processing waste management in the coastal area of ??Kenjeran Beach is very critical to the environment. The production process of smoked fish has also created various solid wastes in the form of offal, head, tail, and fish fins. In this case, the solid wastes produced were disposed of without any prior management thus it can cause environmental pollution to reduce the pollution, it is necessary to utilize it to minimize the pollution. Bulak Fish Center Surabaya has plenty of smoked fish retailers selling their catches. Waste management has not been carried out optimally because it was relatively expensive for retail scale traders, so there needs to be an alternative utilization of fish waste. Wastes generated from smoked fish have great potential to be used as raw material for fish feeds with a fairly high content of protein and lipids. In addition to protein and amino acid sources, fish waste also contains minerals and vitamins. Utilization of smoked fish waste such as innards in the form of digestive organs, heads, and tails of these fish can be used as fish pellets raw material. The knowledge about waste and how to utilize the waste as fish feed needs to be informed to the fish processing business owners and the community around the Bulak Fish Center Surabaya. This community service will provide basic knowledge, and counseling, and become a pioneer of fish feed production so that it can be applied as fish feed materials used for fish cultivation.

Proses koagulasi dan flokulasi secara mekanik merupakan proses yang sering digunakan dalam mencampurkan koagulan dengan air sampel. Hidroulik koagulasi merupakan proses koagulasi yang digunakan mencampurkan koagulan secara hidroulik, yaitu dengan manfaatkan aliran air untuk pengadukannya. Parshall Flume merupakan unit yang biasanya diganakan dalam proses aerasi. Unit Parshall flume memanfaatkan betuk penyempitan saluran untuk membentuk suatu terjunan. Pada titik dipenyempitan saluran Parshall Flume dimanfaatkan sebagai proses pencampuran antara koagulan dengan air yang akan diolah. Sehingga Debit aliran yang melalui penyempitan saluran tersebut berpengaruh terhadap tinggi terjunan nya. Level air pada terjunan akan menimbulkan kontak pula antara air dengan udara, sehingga perlu diketahui nilai Dissolve Oxygen yang turut mempengaruhi proses penyisihan senyawa organik yang berada pada air yang akan diolah. Variasi debit dan variasi koagulan digunakan untuk mengetahui nilai optimum aliran dan koagulan dalam menyisihkan senyawa organik

The abundance of microplastics in Surabaya's surface water can disrupt the sustainability of the river ecosystem and have a bad impact on humans. Because most of the raw water used by the people of Surabaya comes from surface water. Microplastics less than 5µm in size contain hazardous chemicals such as Polycroline Binefil (PCB) and are toxic. Microplastics can carry heavy metals and also some pathogenic microorganisms that attach to the microplastic body, this can possibly enter the bloodstream and infect the body. One of the processing alternatives that can be used to reduce microplastic levels is to use electrocoagulation. Electrocoagulation is the process of clumping and depositing fine particles in water using electrical energy. Microplastics contained in water are removed through a process of flocculation and deposition. This study aims to determine the effectiveness of reducing levels of microplastics using electrocoagulation with variations in the distance between electrodes and detention time. The variation of the distance between the electrodes used was 1.5 cm; 2 cm; 3cm; and 5 cm. From the research conducted, it was found that in order to reduce the microplastic levels in surface water samples, the most effective distance between electrodes was 3 cm with a decrease in microplastic levels by 89%.

ABSTRACT Leachate contains high levels of organic matter, TSS and ammonia. Moving Bed Biofilm Reactor (MBBR) is a biological treatment that can reduce the concentration contained in leachate. The purpose of this study was to determine the ability of MBBR to reduce the content of organic matter, TSS, and ammonia, by using variations in the detention time of aerobic-anoxic processes and sticky media. This research is a laboratory scale research. Leachate samples came from the Kotawaringin Timur TPA Inlet. The reactor is operated in batches. During the aerobic process the moving media is assisted by an aerator pump and submersible pump, while in the anoxic process it is only from a submersible pump. The MBBR processing used has a capacity of 5L with a media capacity of 2L. The variations of the media used were K1 and K3 caldness, while the aerobic detention time was 14.5 hours - anoxic 10 hours and aerobic 10 hours anoxic 7 hours. The results obtained show that MBBR can be used to treat leachate. The best decrease in COD, TSS, and ammonia concentrations occurred in K1 media with 14.5-anoxic 10-hour aerobic detention time with a reduction of 74.8%, 93.14%, and 83.72%.
