Gangguan antropogenik di wilayah pesisir akhir-akhir ini meningkat karena peningkatan populasi. Gangguan yang dimaksud dapat berupa produk kegiatan manusia yang merusak ekosistem di sekitarnya, seperti sampah, pembangunan industri, perumahan dan fasilitas umum. Salah satu ekosistem yang terancam dari gangguan tersebut adalah ekosistem mangrove. Ekosistem mangrove memiliki berbagai peran bagi lingkungan dan manusia, salah satunya sebagai habitat biota seperti burung air, yang memanfaatkan ekosistem mangrove sebagai tempat bersarang dan mencari mangsa. Pengaruh gangguan antropogenik terhadap lingkungan diketahui melalui media yang mampu menunjukkan hubungan antara keduanya, seperti Index of Waterbird Community Integrity (IWCI) dimana burung air digunakan sebagai bioindikator perubahan kualitas lingkungan. Penelitian ini bertujuan untuk mengetahui hubungan antara faktor gangguan antropogenik berupa penggunaan lahan, jumlah pengunjung, polusi suara, kecerahan air dan kadar fosfat terhadap kualitas lingkungan melalui penilaian skor IWCI. Penelitian dilakukan di Taman Wisata Alam Angke Kapuk (TWAAK) pada bulan Oktober hingga November tahun 2019. Sebanyak 17 jenis burung air berhasil diidentifikasi. Hasil penelitian menunjukkan bahwa nilai IWCI dalam TWAAK berkisar antara 13,75 hingga 17,61 dengan rata-rata 16,02. Berdasarkan kriteria skor IWCI, nilai rata-rata menunjukkan bahwa kualitas lingkungan TWAAK tergolong 'buruk-sedang'. Data korelasi gangguan antropogenik dan skor IWCI menunjukkan hubungan negatif yang signifikan terhadap jumlah pengunjung dan persentase penggunaan lahan. Hasil analisis regresi menunjukkan bahwa hubungan yang signifikan antara jumlah pengunjung mempengaruhi nilai IWCI sebesar -0,109 dan persentase penggunaan lahan yang paling signifikan adalah -0,136. ......Anthropogenic disturbances in coastal areas have recently increased due to population growth. The disturbance in question can be in the form of a product of human activities that damage the surrounding ecosystem, such as garbage, industrial development, housing and public facilities. One of the ecosystems that are threatened from this disturbance is the mangrove ecosystem. Mangrove ecosystems have various roles for the environment and humans, one of which is as a habitat for biota such as water birds, which use the mangrove ecosystem as a place to nest and find prey. The influence of anthropogenic disturbances on the environment is known through media that are able to show the relationship between the two, such as the Index of Waterbird Community Integrity (IWCI) where waterbirds are used as bioindicators of changes in environmental quality. This study aims to determine the relationship between anthropogenic disturbance factors in the form of land use, number of visitors, noise pollution, water brightness and phosphate levels on environmental quality through an IWCI score assessment. The research was conducted at the Angke Kapuk Nature Tourism Park (TWAAK) from October to November 2019. A total of 17 species of water birds were identified. The results showed that the IWCI value in the TWAAK ranged from 13.75 to 17.61 with an average of 16.02. Based on the IWCI score criteria, the average score indicates that the environmental quality of TWAAK is classified as 'poor-moderate'. Correlation data of anthropogenic disturbances and IWCI scores showed a significant negative relationship to the number of visitors and the percentage of land use. The results of the regression analysis showed that the significant relationship between the number of visitors affected the IWCI value of -0.109 and the most significant percentage of land use was -0.136.

Perubahan dalam lingkungan oleh aktivitas manusia dapat berasosiasi dengan akumulasi logam berat dan berpotensi meninggalkan jejak antropogenik dalam rekaman sedimen laut. Penelitian akan kondisi kemostratigrafi dilakukan untuk menentukan pengaruh aktivitas antropogenik di Perairan Banggai, yang dinilai tinggi karena fungsinya sebagai wilayah penangkapan ikan dan berdekatan dengan Pulau Taliabu, kepulauan agrikultural dengan potensi tambang yang tinggi. Penelitian ini dilakukan dengan melakukan penanggalan umur (dating) dengan isotop 210Pb, analisis logam berat, distribusi ukuran butir, dan kandungan TOC untuk menganalisis dan merekonstruksi perubahan lingkungan. Penanggalan menggunakan isotop 210Pb dilakukan menggunakan spektrometer alfa (AAS), logam berat dianalisis menggunakan spektrometri emisi optikal (ICP-OES), distribusi ukuran butir dianalisis menggunakan difraksi laser (LDS), dan kandungan TOC dianalisis menggunakan LOI. Hasil analisis menunjukkan bahwa distribusi konsentrasi logam berat dalam sedimen core BC-06 menghasilkan nilai geo-accumulation index dan enrichment factor yang rendah, dan menunjukkan bahwa sumber logam berat yang ditemukan merupakan campuran alamiah dan antropogenik. Jejak logam berat dengan pengaruh antropogenik dalam sedimen core BC-06 dapat dibagi menjadi tiga periode, yaitu: (I) 1831-1927 AD, (II) 1927-1994 AD, dan (III) 1994-2022 AD, yang diinterpretasi berhubungan dengan ekspansi militer pada zaman pemerintahan Hindia-Belanda dan perkembangan berbagai sektor perekonomian Indonesia modern. ......Changes in the environment by human activities is associated with heavy metal accumulation and can potentially leave anthropogenic traces in marine sediment records. Research focusing on the chemostratigraphic condition was done to determine the impacts made by anthropogenic activities in Banggai Waters, that are considered high because of its function as fishing grounds and is located near Taliabu Islands, which are agricultural lands with high mining potential. This research was done by Pb-210 dating, heavy metal, grain size distribution, dan TOC content analyses, to analyse and reconstruct environmental changes. Pb-210 dating was conducted by alpha spectrometer (AAS), heavy metal analysis was conducted by optical emission spectrometry (ICP-OES), grain size distribution analysis was conducted by laser diffraction (LDS), and TOC content analysis was conducted by the LOI method. Results show that heavy metal concentration distribution in sediment core BC-06 yield low values for geo-accumulation index (Igeo) and enrichment factor (EF), and showed that the metals found has a mixed source of natural and anthropogenic. Heavy metal traces with anthropogenic influence can be divided into three periods, such as: (I) 1831-1927 AD, (II) 1927-1994 AD, dan (III) 1994-2022 AD, which are interpreted as related to the military expansion during The Dutch’s colonialism, alongside the development of various economic sectors in modern Indonesia.
