Abstract

Kelagian Lunik Island is located in Pesawaran Regency which has three ecosystems that are mangrove, seagrass, and beaches ecosystems. These three ecosystems affect the survival of one of the biotas living on the substrate of the water that is macrozoobenthos. Macrozoobenthos are invertebrate biota that live on the base of the substrate or inside the substrate. The role that is large enough in the aquatic ecosystem is to describe the organic matter that falls to the water base. It is therefore the research to study the diversity and abundance of macrozoobenthos. This research was conducted in December 2019 to January 2020 located on Kelagian Lunik Island, Padang Cermin District, Pesawaran Regency, Lampung Province. The method is purposive sampling at five stations with three repetitions. The results show that the highest abundance found in the species Tellina perna with 2880 ind/m3 on Station 1, Nassarius globosus with 1851 ind/m3 on station 2, and Marshalora adversa with 1645 ind/m3, 2674 ind/m3, and 1851 ind/m3 at stations 3, 4 and 5. The biodiversity of macrozoobenthos such as the index of diversity and uniformity in the waters of Kelagian Lunik Island is relatively high and the dominant index is relatively low thereby the condition of the water can fit in the good category.

Abstract

Pasaran Island waters is the location of green mussel cultivation (Perna viridis), where the waters has the potential to experience heavy metal pollution including Cadmium (Cd). Green mussels are filter feeders and have a slow movement, thus they have the potential to experience heavy metal bioconcentration on their bodies. The aim of this study was to determine the bioconcentration of heavy metal cadmium (Cd) in green mussels (Perna viridis) which were cultivated in the waters of Pasaran Island. Samples were collected in February 2018 in green mussel cultivating cages of Pasaran Island water with 3 and 6 cm mussel size. Sampling was taken at three stations with three replications each. The Cd content was analyzed using AAS method. The results showed that the water content of Cd at the observation location ranged from 0.022 to 0.024 mg/l. The content of Cd of mussel meat is 0.030 to 0.033 mg/kg, the value is below the threshold based on Indonesian National Standard (SNI). The BFC value of 3 cm mussel is 1.33 mg/kg, while the 6 cm mussel is 1.47 mg/kg which indicates that the green mussels on Pasaran Island are accumulatively low on Cd.

Abstract

This research was conducted from May to June 2020, located at Sari Ringgung Beach, Pesawaran District, Lampung Province. This study aims to assess the ecological conditions of Enhalus acoroides seagrass and to analyze the relationship between Enhalus acoroides ecosystem and water quality. Determination of observation points using purposive sampling method. Data on seagrass conditions and measurement of water quality parameters were carried out using a quadratic transect measuring 50 cm x 50 cm. The relationship between seagrass density and coverage with water quality parameters was tested using principal component analysis (PCA). The results showed that the type of seagrass vegetation at Sari Ringgung beach was single with the type of seagrass Enhalus acoroides. The highest average density value of Enhalus acoroides was at station 3 with a range of 76 individuals / m2 and the lowest density was at station 1 with a range of 36 individuals / m2. Meanwhile, the highest average value of Enhalus acoroides cover was at station 3 with a range of 48.48% / m2 and the lowest was at station 1 with 25.0% / m2. Seagrass density and cover have a positive correlation with phosphate, temperature, depth, brightness, and current and negatively correlated with parameters TDS, TSS, salinity, dissolved oxygen (DO), pH and nitrate.

Abstract

Raman River is located in Purwoasri Village, North Metro District, Metro City. People use this river for various purposes, namely irrigation for rice fields , fisheries, transportation, tourism, and other uses. The increasing use of rivers by the community might caused a negative impact to the waters quality and affect the organisms living there, such as macrozobenthos. The purpose of this study was to analyze the pollution status of the Raman River waters based on the macrozoobenthos community structure. Sampling was done from April to Mei 2020. The research location was determined using a survey method and the sampling was carried out by purposive sampling. The data obtained were analyzed using Abudance-Biomass Comparison (ABC) method. The analysis showed that Raman River is moderately contaminated.Keywords: macrozoobenthos, Raman River, pollution stastus

Abstract

Desa Tarahan Kecamatan Katibung merupakan salah satu wilayah di Kabupaten Lampung Selatan yang memiliki luas wilayah ± 40.20 Ha. Desa ini berada di Kawasan yang cukup unik karena merupakan perpaduan fungsi sebagai kawasan konservasi, wisata yan dinamakan Pantai Sembalang dan industri. Meningkatnya aktivitas antropogenik di kawasan tersebut menyebabkan besarnya tekanan yang diterima, termasuk pada daerah pantai. Salah satu masalah yang signifikan penyebab degradasi lingkungan adalah sampah, termasuk sampah laut (marine debris). Tujuan dari pengabdian ini untuk melihat pemahaman masyarakat terhadap sampah laut, di sekitar kawasan Pantai Sembalang. Kegiatan dilakukan dalam dua tahap untuk mengobservasi sampah laut dan pemahaman masyarakat. Asil yan didapat dari kegiatan ini adalah jenis sampah yang mendominasi berbahan dasar plastik karena berada di wilayah kegiatan pariwisata dan terdapat variasi pemahaman yang ada pada responden tentang marine debris dan memiliki pemahaman yang tinggi tentang sikap menjaga lingkungan
