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.

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.

The Sugio–Tlanak Road Section, Sugio District, Lamongan Regency, is a vital transportation infrastructure as it connects interregional activities, both in economic, social, and community mobility aspects. This road is the main route used by various types of vehicles, from light vehicles to heavy vehicles with quite high traffic intensity. This condition has a significant impact on the quality of the road pavement, as indicated by the presence of various types of damage at several points, such as cracks, potholes, and road surface deformation. Therefore, a comprehensive evaluation is needed to determine the level of road damage as a basis for consideration in planning maintenance and repairs. This study uses two assessment methods, namely the Bina Marga method and the Pavement Condition Index (PCI). The Bina Marga method assesses road conditions based on the Surface Distress Index (SDI) value obtained from direct identification in the field. The evaluation results show that the road condition on the Sugio–Tlanak section is classified as severely damaged at 60%, moderately damaged at 30%, and good condition at only 10%. Meanwhile, the PCI method provides results in the form of more detailed quantitative values. The analysis results obtained an average PCI score of 58.6, which is included in the Fair category. A comparison of the two methods shows that the Bina Marga method has advantages in terms of speed and ease of implementation, but its assessment is relatively subjective. In contrast, the PCI method provides more accurate and measurable results because it uses a quantitative approach with clear damage condition parameters. Therefore, although the Bina Marga method can still be used for rapid assessments in the field, the PCI method is more recommended as a basis for technical decision-making in planning road maintenance and quality improvement programs.
