Laguna Segara Anakan (LSA) Cilacap yang terletak di antara Jawa dan Nusakambangan, Jawa Tengah, merupakan habitat yang baik bagi biota makrozoobentos. Habitat tersebut dicirikan dengan sedimen pasir, debu dan liat. Identifikasi dan analisis keanekaragaman makrozoobentos penting untuk menentukan kondisi ekosistem. Tujuan dari penelitian ini adalah untuk mengetahui jenis tekstur sedimen dan untuk mengetahui kualitas perairan dengan menerapkan bioindikator menggunakan makrozoobentos. Metode yang digunakan yaitu survei dan penggambilan sampel secara acak dilakukan pada saat mengambil sampel sedimen dan makrozoobentos pada 12 titik penenilitian menggunkaan hand packing dengan bantuan cetok. Pengambilan sampel dilakukan pada bulan September – November 2023. Untuk mengetahui pengaruh tekstur sedimen terhadap FBI makrozoobentos dianalisis secara regresi. Hasil penelitian tekstur sedimen fraksi pasir berkisar 1,09-1,7%; fraksi debu berkisar 31,43-48,31% dan fraksi liat berkisar 50,6-67,17%. FBI makrozoobentos berkisar antara 7,097-7,399 yang berarti kondisi perairan di LSA Cilacap dalam kategori buruk – sangat buruk. Tekstur sedimen fraksi pasir terhadap FBI makrozoobentos memiliki pengaruh yang sangat kuat dengan nilai regresi 0,916 sedangkan tekstur sedimen fraksi liat (R = 0,223) dan debu (R = 0,198) memiliki pengaruh yang lemah terhadap FBI makrozoobentos. Segara Anakan Lagoon (LSA) Cilacap, which is located between Java and Nusakambangan, Central Java, is a good habitat for macrozoobenthic biota. This habitat is characterized by sand, dust and clay sediments. Identification and analysis of macrozoobenthos diversity is important for determining ecosystem conditions. The aim of this research is to determine the type of sediment texture and to determine water quality by applying bioindicators using macrozoobenthos. The method used was a survey and random sampling carried out when taking sediment and macrozoobenthos samples at 12 research points using hand packing with the help of a spat. Sampling was carried out in September – November 2023. To determine the effect of sediment texture on the macrozoobenthos FBI, it was analyzed using regression. The results of the sediment texture research, the sand fraction ranged from 1.09-1.7%; the dust fraction ranges from 31.43-48.31% and the clay fraction ranges from 50.6-67.17%. The FBI macrozoobenthos ranges from 7,097-7,399, which means that the water conditions in the Cilacap LSA are in the bad – very bad category. The sand fraction sediment texture on macrozoobenthos FBI had a very strong influence with a regression value of 0.916, while the clay fraction sediment texture (R = 0.223) and dust (R = 0.198) had a weak influence on macrozoobenthos FBI.

Fresh waters in Indonesia are strongly broad and play a role for aquaculture as well as human activities, thus impacting water quality and river ecosystems. Periphyton acts as a natural food source. This study aimed to determine the abundance of periphyton species as natural food for fish in the Banjaran River, and the quality of river water. Survey method and purposive sampling were used and conducted at four stations. This research was conducted in situ and ex situ and the test results were analyzed descriptively quantitatively. The percentage of periphyton abundance the Banjaran River is 28% from the class Bacillariophyceae (25 species), 21% Chlorophyceae (9 species), 21% Cyanophyceae (3 species), 16% Eugelenophyceae (2 species), and 16% Rhizopoda class (1 species). The abundance of periphyton at each station was 3,275–5,574 individuals/cm² with species abundance values of 26–22,904 individuals/cm², while the percentage values for the abundance of each class were Bacillariophycae (82%), Chlorophyceae (9%), Eugelenophyceae (6%), Cyanophyceae (2%), and Rhizopoda (1%). The water quality that greatly influences the value of periphyton abundance is TDS (Total Dissolved Solid). The influence of TDS content on the abundance of periphyton was 0.8 and the influence was negative.

Microplastics in the digestive tracts of fish can make their way into the food chain, reaching higher trophic levels, including humans, and potentially causing health issues. The Banjaran River in Banyumas Regency is one such waterway at risk of microplastic pollution. This study aimed to identify the types and abundance of microplastics in fish from the Banjaran River. Sampling was conducted at four strategically chosen stations based on land use, with three repetitions at two-week intervals. Analysis of the type composition and abundance of microplastics in the fish digestive tract using laboratory testing with microscope observations. Four types of microplastics were found in all samples with a predominance of fiber (37%), fragments (31%), pellets (19%), and film (14%). The abundance of microplastics in the fish digestive tract ranges from 12.8-20.5 particles/individual. The highest abundance of microplastics was found in broomstick fish, while the lowest abundance of microplastics was found in broomstick fish.Keywords: Banjaran River; Fish Digestion; Microplastics

The Banjaran River is one of the rivers in the Banyumas Regency. This research aims to produce information related to macrozoobenthic community structure as a bioindicator of water quality in the Banjaran River and to produce information related to water quality in the Banjaran River for macrozoobenthic life. The research was conducted in September 2022 - February 2023 on the Banjaran River, Banyumas. This research uses a survey method, sampling was carried out 3 times in September-November 2022. The sampling method was purposive random sampling, namely the river was divided into 3 stations based on certain criteria. The results of this research obtained 15 species and were divided into 11 families, namely Perlidae, Psychomyiidae, Thiaridae, Lumbricidae, Naididae, Gecarcinucidae, Palaemonidae, Elmidae, Hydropsychidae, Atyidae, and Chironomidae in the Banjaran River. The highest abundance of individuals was at station two, namely 3156 individuals/m2. The dominant species is Melanoides tuberculata with an abundance of 1852 individuals/m2 at station two. The dominance index values at the three stations ranged from 0.1864 to 0.2886, which is relatively low. The water quality in the Banjaran River for macrozoobenthic life is still quite good based on the results of measuring environmental parameters which consist of physical parameters, namely water temperature and current speed.Keywords: Banjaran River, Macrozoobenthos Community, Water Quality Indicators

Plastic waste is a serious environmental problem for all countries in the world, including Indonesia. Plastic waste of various sizes can have a negative impact, especially microplastics. Microplastic contamination can be found in aquatic sediments. One of the waters potentially polluted by microplastics is the Banjaran River, Banyumas Regency. This research was conducted to determine the composition and abundance of microplastics as well as the effect of sediment texture on the composition and abundance of microplastics in the sediments of Banjaran River, Banyumas Regency. The research location was determined using purposive sampling at four stations. At each station, samples were taken randomly at three different places with three repetitions. Analysis of the composition and abundance of microplastics in sediments was done in a laboratory using microscope observation. Sediment texture analysis was done using a dry sieve and pipetting method. Five types of microplastics were found in all sediment samples with a predominance of fiber (35%), followed by fragments (29%), films (19%), pellets (10%) and foam (7%). The abundance of microplastics in sediments ranged from 2.3 to 4.86 particles/50 grams of dry sediment. The sediment texture that dominated the four stations was sand, with an average fraction proportion value of 86.62%. Sediment texture had the strongest effect on the composition of fragment-type microplastic at 50.2% and had the same impact on the overall abundance at 56%, which indicated that the sediment texture had a significant effect on these two variables.
