Abstract

The objective of this study was to determine the mercury content in sediment in the waters of Aceh Jaya coastal. The research was carried out in the Estuary of Krueng Sabee, Panga, and Teunom River on October 2015. Samples were analyzed using the Atomic Absorption Spectrophotometer (AAS) at the Laboratory of Chemistry, Mathematics and Natural Sciences Faculty, Syiah Kuala University. It was found that the Hg content in sediment of Krueng Sabee, Panga, and Teunom were 0.76, 0.68, and 1.03 mg/kg, respectively. Hg metal content in the sediment at all stations remained below the threshold. Despite,  the correlation between Hg content and sediment size in this study was weak, but there was a tendency the finer sediment size the higher Hg content found in sediment. However, heavy metal from water was easier to be deposed and embedded in fine sediment.Tujuan dilakukannya penelitian ini adalah untuk mengetahui sebaran logam berat merkuri (Hg) yang terkandung pada substrat dasar di beberapa muara sungai Kabupaten Aceh Jaya. Pengambilan data dilakukan pada Bulan Oktober 2015 di Krueng Sabee, Krueng Panga, dan Krueng Teunom. Sampel substrat diambil berdasarkan metode coring menggunakan pipa paralon, Atomic Absorption Spectrophotometer (AAS) atau Spektrofotometer Serapan Atom digunakan untuk mendapatkan data kandungan logam berat Hg pada substrat, sementara metode ayak basah digunakan untuk mendapatkan data ukuran butiran. Kandungan merkuri (Hg) dalam substrat Krueng Sabee, Krueng Panga, dan Krueng Teunom masing-masing adalah 0,76; 0,68 dan 1,03 mg/kg. Terlihat kecenderungan substrat dengan butiran yang halus mengandung kadar merkuri yang lebih tinggi, dimana sifat merkuri yang mudah berikatan dengan zat organik mempermudah pengendapan pada bentuk butiran yang halus.

Abstract

Abstract. Mismanaged anthropogenic debris land-based has generated the waste entering the river runoff. It was documented that the ocean has been affected ecologically by the waste. Therefore, the data availability of riverine inorganic debris is crucial in implementing mitigation strategies. This study was a preliminary study to identify the inorganic debris floating on the Krueng Aceh River. This study aimed to obtain data of floating inorganic debris types and percentages found at the estuary of Krueng Aceh River that can be used as a reference in managing the riverine waste. It was conducted at the estuary of Krueng Aceh River, Banda Aceh, during March to April 2019. The samples were collected twice a week by installing 4 m x 2 m nets on both sides of the river for six hours. It was identified seven categories of inorganic debris were plastic, foamed plastic, metal, glass, rubber, paper and cardboard, and others. Plastic category as the most floated on Krueng Aceh River with the percentage of 77.8% consists of drinking water bottles and cups, bottle caps, cigarettes, cigarettes lighter, bubble wrap, plastic bags, plastic ropes, monofilament line, straws, and drink package rings. The amount of drinking water cups was dominantly trapped (32%) and identified as many as 28 brands. The plastic debris was assumed originating from anthropogenic activities, and mismanaged land-based garbages.It is concluded that the plastic category, especially drinking water cups, was the most floating on the Krueng Aceh River.Keywords: Mineral water bottles, floating plastic debris, Krueng Aceh River Abstrak. Sampah anorganik akibat aktivitas manusia yang tidak dikelola dengan baik telah menghasilkan limbah yang berada di aliran sungai. Sebagian dari sampah–sampah tersebut akan berakhir di lautan sehingga menimbulkan dampak negatif secara ekologi. Oleh karena itu, ketersediaan data sampah anorganik di aliran sungai diperlukan bagi pengelolaan sampah yang lebih baik. Penelitian tentang sampah anorganik di muara Sungai Krueng Aceh merupakan penelitian awal untuk menyediakan data jenis dan persentase sampah anorganik yang ditemukan di muara Sungai Krueng Aceh. Tujuan dari penelitian ini adalah mengidentifikasi jenis-jenis dan persentase sampah anorganik yang terapung di muara Sungai Krueng Aceh sehingga dapat menjadi acuan bagi pengelolaan sampah di aliran sungai. Penelitian ini dilakukan di muara Sungai Krueng Aceh, Kota Banda Aceh pada bulan Maret-April 2019. Pengumpulan sampel dilakukan dua kali dalam seminggu dengan memasang jaring 4 m x 2 m di kedua sisi sungai selama enam jam. Hasil identifikasi dikelompokkan ke dalam tujuh kategori sampah anorganik, yaitu kategori plastik, busa, kaca dan keramik, logam, kertas dan kardus, karet, serta kategori lainnya. Kategori plastik memiliki persentase terbesar dengan nilai 77,8% yang terdiri dari jenis bentuk botol dan gelas Air Minum Dalam Kemasan (AMDK), puntung rokok, pemantik, bubble wrap, kantong plastik, tutup botol, tali plastik, monofilament line, sedotan, dan cincin paket minuman. Persentase AMDK berbentuk gelas lebih tinggi daripada bentuk botol dengan 28 merek yang teridentifikasi. Sampah plastik tersebut diduga berasal dari aktivitas masyarakat di sepanjang Sungai Krueng Aceh dan akibat pengelolaan sampah yang belum baik sehingga sampah memasuki aliran sungai. Berdasarkan hasil penelitian dapat disimpulkan bahwa sampah plastik terutama sampah AMDK bentuk gelas ditemukan paling banyak mengapung di Sungai Krueng Aceh.Kata kunci: Air Minum Dalam Kemasan (AMDK), sampah plastik apung, Sungai Krueng Aceh

Abstract

This study aimed to examine the influences of the Indian Ocean Dipole (IOD) on rainfall in three districts in South Aceh. The analysis was undertaken using Dipole Mode Index (DMI) data and five years of rainfall (2016 to 2020) in West Labuhan Haji, Tapak Tuan, and Bakongan areas. This research employed a correlation analysis and the Principal Component Analysis, followed by Cluster Analysis to investigate the relationship between IOD and rainfall at the study location. The negative IOD occurred in 2016, and the positive IOD occurred in 2017, 2018, 2019, and 2020. The strongest positive DMI was in October 2019 (1.123˚C), while the strongest negative DMI was in July 2016 (0.661˚C). Generally, the sub-districts of West Labuhan Haji, Tapak Tuan, and Bakongan always have high rainfall. The highest rainfall in West Labuhan Haji was recorded in January 2017 (1014 mm/month), in Tapak Tuan in November 2017 (1073 mm/month), and in Bakongan in July 2020 (605 mm/month). The correlation between DMI and rainfall in the three locations shows different findings. Although it was very small, the IOD affected the rainfall in West Labuhan Haji, Tapak Tuan, and Bakongan. In West Labuhan Haji, the highest correlation was in lag 1 (0.188); in Tapak Tuan, the highest correlation was in lag 2 (0.156), while in Bakongan, the highest correlation was in lag 2 (-0.191). The correlations in these three locations are considered weak. Thus, the IOD is not the main factor affecting the rainfall in West Labuhan Haji, Tapak Tuan, and Bakongan. As South Aceh is located in windward, the orographic effect may influence high rainfall in this region.Keywords:DMIRainfallPrincipal component AnalysisWest Labuhan HajiTapak TuanBakongan
