Abstract

The existence of many fisheries products is directly proportional to the number of existing fish markets, including the Sidoarjo Fish Market in the eastern ring area. The many activities in this fish market produce wastewater that must be considered for its management so as not to pollute the surrounding environment. These activities forexample from fish washing activities. The parameters of water used for washing fish are organic, with organic pollutants high enough, namely COD. The purpose of this study was to determine the reduction in levels of BOD (5,20) treatment of wastewater from fish washing from the Sidoarjo Fish Market using sedimentation tub reactors and Rapid Sand Filters (RSF). The research phase will be carried out using a laboratory scale using a Precipitating Body as a pretreatment and RSF as a secondary treatment. The research began with a preliminary test to determine the influent quality of fish washing water effluents, then pretreatment was conducted. RSF uses buffer media in the form of: zeolith and gravel Influent discharge effluents are varied in two variables 10 liters / dayand 15 liters / day. The processing results from the RSF were then analyzed by BOD parameters (5.20) for 4 consecutive days using the standard EPHA method. The results showed that treating fish washing wastewater using sedimentation tanks and RSF can reduce the content of organic pollutants through BOD parameters (5.20) with an effectiveness reaching an average of 90% with gravel media and 95% with zeolith media. So it can be concluded that the fish washing wastewater from the Sidoarjo fish market can be treated before being discharged into the river so that the BOD pollutant can be reduced up to 95% using RSF technology with zeolith media. Keywords: Fish Washing Liquid Waste, BOD, Rapid Sand Filter, Zeolith.

Abstract

DPI Kabpaten Sidoarjo produces liquid waste from the fish washing process, which has the potential to pollute the environment. The results of the laboratory test of liquid waste produced by DPI Kabupaten Sidoarjo contains 764 mg/L BOD and 1.440 mg/L COD. DPI Kabupaten Sidoarjo uses phytoremediation methods with water hyacinth (Eichornia crassipes) and water spinach (Ipomoea aquatic). The parameters analysed were BOD5, COD, TSS, and TDS and biodegradability ratio. The reactor used was a 25 L batch reactor and the residence time used was 6 days. The results obtained by water hyacinth plants were able to reduce COD and BOD5 levels better than water spinach, namely 98.60% and 98.70%. Then the results of the TDS parameters of the water hyacinth reactor also got the lowest concentration of 368 ppm. For TSS parameters the best value was obtained from the water spinach reactor with a value of 400 mg/L. The pH parameters of the water hyacinth reactor and water spinach got a value between 6-7. The best biodegradability ratio was obtained from the water hyacinth plant reactor, which was 0.5-0.53.

Abstract

Sidoarjo Regency is a buffer zone for industrial estates in Surabaya, East Java Province. Therefore, the economic growth of the Sidoarjo Regency is increasing along with the development of trade and industrial potential. One of the industries that have grown well in Sidoarjo Regency is the tofu factory. Many tofu craftsmen industry causes an increase in the volume of liquid waste which also flows into water bodies. The purpose of this study was to determine the reduction of TDS and ammonia levels in the tofu factory wastewater treatment in the Sepande area, Sidoarjo Regency, by using a wetland construction with a Typha latifolia remediator. The research stages will be carried out using a laboratory scale using acclimatization as the adaptation stage of Typha latifolia and a constructed wetland reactor as a phytoremediation process. Based on the results and discussion, it can be concluded that there was a decrease in TDS and ammonia levels in the tofu industrial wastewater in Sidoarjo with the Constructed Wetland system. The largest decline in TDS content was in soil media with three Typha latifolia stems and a detention time of four days by 76%. Meanwhile, the most considerable percentage reduction in ammonia levels occurred in sand media with three stems of Typha latifolia and a detention time of four days by 70%.

Abstract

Micro, Small and Medium Enterprises (MSMEs) are currently one of the important sectors supporting the Indonesian economy. Lack of understanding in the meaning of NIB ownership as a legal form for business actors is a problem for MSMEs and also the community. The same problem was also found in MSMEs in Buduran Village, Sidoarjo. The purpose of this community service is to provide direction to business actors regarding preparing and registering to obtain an NIB. This community service begins with location observations, data collection, and implementation of socialization and mentoring activities. After participating in socialization and mentoring, entrepreneurs have a better understanding and are able to manage and have an NIB. It is hoped that this community service can be carried out irrationally for MSME actors in Sidaorjo Regency.

Abstract

The Dandu Bridge is one of the important infrastructures that functions as a land transportation link on the Suko-Sowominangun section, Lamongan Regency. The current condition shows that the bridge surface has suffered a lot of damage in the form of holes that can interfere with the smooth flow of traffic and endanger the safety of road users. Therefore, regular maintenance is needed so that the function of the bridge as a public facility remains optimal. One of the maintenance methods used is the Detailed Bridge Inspection Report (LPMJ), which aims to identify the condition of the bridge components as a whole. Field work practices carried out by students of the Lamongan Institute of Technology and Business in March-April 2025 are a means to understand the factors that cause damage. The results of the observation show that the damage is not only caused by structural factors, but also by non-structural aspects such as lack of awareness of road users and lack of communication with the surrounding community. Therefore, intensive education is needed for the community regarding the importance of maintaining the sustainability of the bridge's function, including the installation of proper traffic signs to minimize damage. In the LPMJ method, the upper structure components examined include floor plates, girders, and joints. Meanwhile, the lower structure includes pillars, abutments, and foundations. The bridge equipment that was observed included sidewalks, waterways, and railings. Maintenance should not only be focused on physical improvements, but also on social management that involves the active participation of the community, especially in areas with high traffic intensity. In conclusion, the maintenance efforts of the Dandu Bridge require an integrated approach that combines technical improvements and social empowerment, so that the sustainability of its function can be maintained for the long term.

Abstract

Although Malaysia has abundant water resources, some parts of Malaysia are currently facing water shortage problems. The increasing demand for water has sparked initiatives to seek alternative water supplies. Rainwater harvesting has been proposed by governments as part of the solution to alleviate the problem of water scarcity. Literature related to rainwater harvesting is available from a variety of sources. In this study, rainfall was analysed as a crucial factor affecting RWHS efficiency, rainwater potential at different zones for residential, industrial, and commercial. In addition, the study evaluated the rainwater quality that obtain fresh rainfall and roof rainfall. Furthermore, potential of treatment technology for rainwater was suggested to optimate rainwater harvesting.
