Abstract

Buduran River, Sidoarjo Regency, is one of the rivers in Sidoarjo City, which has various functions. The primary function of the Buduran River at the moment is to supply raw material water for one of the PDAM Delta Tirta Sidoarjo, namely the Drinking Water Treatment Plant (IPAM) branch in Siwalanpanji. For this reason, efforts are needed to maintain and monitor river quality using the Qual2Kw method. QUAL2Kw method begins with the determination of 3 segments. Furthermore, an analysis of hydraulic data, water quality, and pollutant sources was carried out, determining the scenarios used, running the QUAL2Kw program, and calculating the carrying capacity of pollution loads. River water quality parameters include pH, BOD, COD, TSS, Phosphate, and Nitrate. Applying the QUAL2Kw method in evaluating the Buduran River with three scenarios according to existing conditions, initial conditions according to quality standards, and trial & error with maximum pollutant load. The capacity value is determined based on the calculation of the difference in pollutant load in scenario three and scenario 2. The result is that the Buduran River is classified as a polluted river, and the negative (-) pollutant load capacity indicates that management is necessary to reduce pollutant loads.

Abstract

The fishing port, which acts as a public agency, provides services and facilitates fishing activities for fishermen. One indicator that the service provided is already optimal is the minimum number of vessels in the process of dismantling fish in the port. The study aims to find out the fishing landing system and the number of ships that landed during the period September–August 2022. The method used is directly through field observations and collecting secondary data to supplement the data obtained. The system applied to each port is different. The port of Pondokdadap applies the queue method as well as the system of nahkoda, where the ship's documents must be submitted and the fisherman's number taken before landing. Boats that want to sell fish to the TPI must be equipped with a catch letter. In the period September–August 2022, the highest number of ships was found in June 2022, with 603. For the smallest number in January 2022, there were 22 ships. Based on the results obtained, it is known that the period of April–September has the highest number, while there is a decrease in the number in October–March. There was an increase in the number of vessels that carried out fishing, which was affected by the fishing season, with the high season in the Eastern season.

Abstract

Periphyton is an attached biota that lives on a substrate. Seagrass meadows and periphyton associate to form an ecological system. Seagrass meadows provide a place of attachment or habitat for periphyton organisms. Periphyton itself is one of the producers of primary productivity in the waters. Baluran National Park is one of the National Parks in which there are land and water habitats, and is a protected area that has natural and native ecosystems. Data collected to support this research included temperature, salinity, dissolved oxygen, pH, nutrients (nitrate and phosphate), seagrass cover data and periphyton data. Physical and chemical water parameters are taken directly on the spot or in-situ. Data collection on seagrass cover and periphyton samples was carried out using a 50 x 50 cm2 quadrant transect. Periphyton community structure analysis includes abundance, diversity index, diversity index and dominance index. Community structure is calculated to determine the community condition of a particular organism, to see its stability and presence in an area.

Abstract

Lumpur Sidoarjo (LUSI) (Sidoarjo mud), which has its center in Porong, Sidoarjo, East Java, has had a major impact on environmental conditions, especially on water quality. Our previous analysis proves that the groundwater in this area has been contaminated, especially by heavy metals. In this case, the presence of contaminants from Fe, Mn, and Hg was detected. Heavy metals in this water will certainly affect human health if this contaminated water is consumed, considering that groundwater is the main water resource utilized by local people in this area. Thus, the objective of this study is assessment of health risk from exposure to Fe, Mn, Zn, As, and Hg in the groundwater near to LUSI. The calculation method used the formula recommended by the United States Environmental Protection Agency (US EPA). Scenario subjects for the calculation included 1) children aged 1-3 years, 2) children aged 4-8, 3) children aged 9-12, 4) career women, and 5) career men. The calculation results show that a Hazard Quotient (HQ) value of more than 1 has been detected in several samples and subjects. The highest HI value is in sample B5, and the smallest is in sample B2. In addition, the calculations show that there is a risk of cancer effects from Hg-contaminated water.

Abstract

The various characteristics of catches and fishing gear provide distinct advantages for fishermen, but these characteristics can cause other problems, namely pressure on stock availability caused by an increase in the number of catches and the use of various types of fishing gear and the efficiency provided. There needs to be good management to handle this. The purpose of this research is to find out the clusterization (grouping) of fishing areas based on the catch and the type of fishing gear in which the results of this study are used as a reference in sustainable fisheries management. This research uses descriptive methods and case studies at PPP Bulu. The analytical method used is the Shannon-Wienner index of diversity (S-W,H'), Margalef richness (R') and clusterization. Clusterization was analyzed using the Hierachical Cluster Analysis (HCA) method to obtain the Euclidean distance. The results showed that the value of diversity has a range of 0-2 and the value of wealth has a range of 1-10. The results of the clusterization show that there are 3 clusters of fishing areas formed based on the catch, while no clusters of fishing areas are formed based on the type of fishing gear operated.

Abstract

Southern waters of Malang are one of the areas in the south of Java where some of its coastal areas have not been electrified. The purpose of this research is to determine the magnitude of wave energy potential in the waters of South Malang. The theoretical amount of wave energy is obtained through wave data processing (wave period, significant wave height, and wave direction) and the results are in the form of the wave energy value with the highest value in 2021 occurring in August with an average value of 40 kW /m - 50 kW/m while in 2022 the highest value occurs in July with an average value of 40 kW/m to 50 kW/m. The technical potential value of wave energy is calculated by adding the efficiency formula from AquaBuOY so that results with the highest technical wave energy potential value are obtained in 2021 in August with an average value of 40 kW/m - 50 kW/m while in 2022 the highest potential wave energy value occurs in July with an average value of 40 kW/m - 50 kw/m. Potential locations are determined based on theoretical and technical potential results and the suitability of placing AquaBuOY so that a station point that meets these criteria is obtained, namely at the 29, 30, and 34 where station 30 is the station that has the closest criteria to effectively installing buoys with the total theoretical energy is 4838.46 MW and technically it is 4354.61 MW in 2021 while in 2022 the total theoretical energy is 4387.95 MW and technically it is 3977.38 MW.
