Pollution with microplastics (MPs), nanoplastics (NPs) and trace elements (TEs) remains a considerable threat for mangrove biomes due to their capability to capture pollutants suspended in the water. This study investigated the abundance and composition of plastics and TEs contained in the soil and pneumatophores of Avicennia alba sampled in experimental areas (hotel, market, river mouth, port, and rural areas) differentiated in anthropopressure, located in Bima Bay, Indonesia. Polymers were extracted and analyzed with the use of a modified sediment isolation method and Fourier transform infrared spectroscopy. Trace elements were detected by inductively coupled plasma optical emission spectrometry. The lowest and highest quantities of MPs in soil were recorded in rural and hotel areas, respectively. The rural site was characterized by distinct MP composition. The amounts of sediment-trapped MPs in the tested localities should be considered as high, and the recognized polymers partly corresponded with local human activity. Concentrations of seven plastic types found in plant tissues did not entirely reflect sediment pollution with nine types, suggesting a selective accumulation (particularly of polyamides and vinylidene chloride) and substance migration from other areas. Very low concentrations of non-biogenic TEs were observed, both in sediments and pneumatophores. The results highlight the relevance of environmental contamination with plastics.

In 2019 we captured specimens of Oreochromismossambicus Peters, 1852 from Batu Batu River, an estuary river on Kangean Island (Indonesia), a conservation area in the Java Sea. These records are among the first of this species from an island in the Java Sea. A description of morphological characters of sampled specimens is provided.

Informasi mengenai distribusi penduduk memiliki peran krusial dalam proses perencanaan dan pengambilan keputusan publik. Namun demikian, Kabupaten Sumbawa yang merupakan wilayah administrasi terluas di Provinsi Nusa Tenggara Barat (NTB), belum memiliki peta distribusi penduduk yang dapat diandalkan. Dalam rangka mengatasi masalah tersebut, penggunaan teknologi informasi, khususnya Sistem Informasi Geografis (SIG), dapat menjadi solusi untuk mengumpulkan dan menganalisis data kependudukan secara efisien. Penelitian ini bertujuan untuk memetakan penduduk secara spasial berbasis sistem grid skala ragam dengn resolusi 0,155 Km x 0,155 Km. Model ini mengintegrasikan data spasial seperti jenis tutupa lahan, jenis jalan, dan batas administrasi daerah, dengan data non-spasial seperti data sensus. Data penduduk Kabupaten Sumbawa sesuai sensus akan didistribusikan pada grid dengan memperhatikan aspek ekonomi dan sosial lahan. Dari penelitian ini diperoleh informasi tentang jumlah penduduk di setiap grid pada wilayah Kabupaten Sumbawa. Penduduk Kabupaten Sumbawa terdistribusi hanya pada lahan yang memiliki fungsi ekonomi dan sosial penting saja. Terdapat 63,72% grid pada wilayah Kabupaten Sumbawa yang tidak berpenduduk, sedangkan 30,31% grid berpenduduk tetapi kepadatannya hanya 1 – 5 penduduk per grid. Berdasarkan kepadatan penduduk taip grid, Kecamatan Sumbawa memiliki beberapa grid dengan konsntrasi penduduk padat, yakni 90 penduduk per grid. Metode sistem grid skala ragam terbukti efektif dalam pemetaan distribusi penduduk di Kabupaten Sumbawa.
