Abstract

The Kalilo River in Banyuwangi plays a vital role in supporting ecosystems and community activities but faces ecological pressures due to human activities. This study aims to analyze the Biological Oxygen Demand (BOD) levels at the upstream and downstream sections of the Kalilo River and their impact on the ecosystem. The research was conducted in December 2024 using standard BOD testing methods through a quantitative and qualitative approach. Water samples were collected from Grogol Village (upstream) and Kampung Ujung Neighborhood (downstream) and tested at the Environmental Laboratory of Banyuwangi Environmental Agency. Results showed that BOD levels were 0.32 mg/L upstream and 1.33 mg/L downstream. Although both sites met the class II water quality standards (≤ 3 mg/L) according to Government Regulation No. 22 of 2021, the higher BOD level downstream indicated organic pollution from domestic activities. The ecological impact includes reduced dissolved oxygen levels, potentially disrupting aquatic life. This study highlights the importance of waste management and continuous water quality monitoring to ensure the sustainability of the Kalilo River ecosystem.

Abstract

Alas Purwo National Park in Banyuwangi is one of the conservation areas of mangrove forest potential big enough one of them is the Teluk Pangpang Blok Jati Papak which is the intertidal area, a lot of marine life that live in the region one of which is the bivalves. This study aims to determine diversity and the distribution pattern of bivalves in the Teluk Pangpang Blok Jati Papak. This study was conducted in 25 Mei - June 1, 2016. Determination of the sampling method used in this research is purposive sampling. Sampling sites are divided into three stations, with the distance between stations is 500 m, in each station there are four transects on each transect contained 10 plot. set the distance between transects 15 m and the distance between the plots 5 m with a plot measuring 2 × 2m. Measurement parameters abiotic do is measure temperature, salinity and pH. The research found 8 species of bivalves that Anomalodiscus squamosus, Placamen chlorotica, Pitar citrus, Chamelea gillina, Mactra grandis, Hiatula chinensis, Tellina timorensis, Anadara granosa. An index value of diversity bivalves in the Teluk Pangpang Blok Jati Papak categorized as low, with the highest index value at station 1 at 0.766 and the lowest at station 2 by 0.66. Biavalvia distribution patterns in the region are random in species Anomalodiscus squamosus, Pitar citrus, Chamelea gillina, Mactra grandis, Hiatula chinensis, Tellina timorensis, Anadara granosa and are clustered in Placamen chlorotica species.
