Marine pollution by microplastics is becoming an increasingly worrying environmental issue, especially for filter feeder organisms such as blood clams (Anadara granosa), which are at high risk of bioaccumulating microplastic particles. This study aims to determine the accumulation rate of 20 µm and 150 µm polystyrene (PS) microplastics in blood clams in environments with different salinities,…
Microplastics and heavy metals are aquatic pollutants that have the poten tial to disrupt the physiological functions of marine organisms, including blood clams (Anadara granosa) as filter feeders. This study aims to analyze the effect of exposure to polypropylene (PP) microplastics, cadmium (Cd) heavy metals, and their combination on lipase digestive enzyme activity. The experiment was con duc…
Peningkatan pencemaran laut oleh mikroplastik, khususnya jenis Polistirena (PS), menimbulkan risiko serius terhadap organisme laut, termasuk kerang darah (Anadara granosa) yang merupakan filter feeder. ingkat akumulasi mikroplastik polistirena dengan dua ukuran berbeda, yaitu 20 μm dan 150 μm, pada kerang darah yang dipelihara dalam suhu berbeda (28°C, 30°C, dan 32°C). Sampel kerang dipero…
The community of gastropods is very influenced by change as which happened in the ecosystera, maritime tourism development give on effect to the community gastropods in Pasir Padi Beach. This research aimed to know the community gastropods in Pangkalpinang City Bangka Belitung Island Province including density, diversity, similarity, dominancy, everest and some environment parameters (temperatu…

The research of Gastropods community in Ringgung Waters, South Lampung was conducted from 30th June until July 2007. The objectives of the research are to know the Gastropods community in Ringgung Waters, especially at location with seagrass and without seagrass. The sample of Gastropods were taken from all plots with the area of 25x25 cm2. The environmental factors such as temperature of water…
Ecosistem of mangrove represent switchover ecosistem between land and sea that have a habitat, spawning ground, nursery ground and feeding ground from kind of fish, as crustacea, mollusc. Gastropods represent amount of mollusc that have a habitat in mangrove forest. This research is detain to see a relationship between gastropods density and mangrove density which is done on march 2006 whitch t…
This research aimed to determine the physical, chemical and sensory characteristics of blood clam (Anadara granosa) broth using the foam mat drying method. This research method used a randomized block design (RBD) with three treatment factors which were repeated 3 times. The treatment in this study was the difference in oven drying temperatures, namely temperatures of 60 oC, 70 oC and 80 oC for…

This research was conducted from March to December 2020. The research method used a randomized block design (RBD) model. With 4 treatments and using 3 repetitions. The treatments given were 10 mesh size sand, 30 mesh size sand, 10 mesh scallop s…
Penelitian ini membahas kerangka acuan mutlak berdasarkan relativitas DSSU dan kontribusinya dalam pembelajaran fisika. Tujuan penelitian ini adalah menerapkan relativitas DSSU pada persamaan transformasi Lorentz, memperoleh persamaan umum dari transformasi Lorentz berdasarkan relativitas DSSU, dan menerapkan persamaan umum dari transformasi Lorentz berdasarkan relativitas DSSU pada persamaan d…
Rangka pondasi adalah hal penting dari komponen alat dalam hal ini kursi roda listrik, maka dari itu rangka harus lah kuat ringan dan tahan lama. Hal inilah yang mendasari penulis menggunakan program aplikasi dari SolidWorks 2012 SP0.0. Analisa simulasi terhadap tegangan pada redesain kursi listrik menunjukkan bahwa redesain konstruksi kursi sangat baik sehingga tegangan berada di bawah batas…
