“…Pollution of the marine environment is caused by the results of the activity of living organisms that enter the marine environment. The content of heavy metals in sediments is strongly influenced by natural and anthropogenic sources (Rustam et al, 2018). CONCLUSION Variability occurs in Pb, Cu, and Cd metals in sediments which are not only influenced by coastal processes but also metal sources.…”

This area, which is located near the Banten Bay, is quite active with anthropogenic activities such as industry, fisheries, settlements, and shipyards that have the potential to pollute the environment with heavy metals. This study aims to determine the chemical environmental conditions of the waters and the concentration of heavy metals in the sediments of Banten Bay. Sediment samples were taken at five stations consisting of river and bay sections in April, May, July, August, and September 2019. Heavy metal content in sediments was analyzed according to APHA 2012 using hydrochloric acid and nitric acid destruction methods. The results of heavy metal concentrations in sediments were compared with ANZECC 2000 regulations and sediment quality was determined using the Geo-accumulation Index. The sediment at the observation site is dominated by the silt fraction. The concentration of heavy metals in this study was obtained in the form of lead (Pb) ranging from <0.05 to 6.408 mg / Kg, copper (Cu) ranging from 0.059 to 8.791 mg / Kg, and cadmium (Cd) ranging from 0.042 to 0.605 mg / K. While based on The level of heavy metal contamination in sediments using the Geo-accumulation index (I Geo), the value of all metal types in each month has a value <0.000 at all observation stations. Thus it is concluded that the concentration of heavy metals in the sediment is lower than the threshold determined during the observation. So that the metal concentration weight in the sediment has no significant effect on the environment.

“…Selanjutnya dilakukan uji Two Way Anova untuk mengetahui perbedaan antar perlakuan (Aziza dan Zahruddin, 2010). Jika terdapat perbedaan antar perlakuan, selanjutnya dilakukan uji lanjut untuk mengetahui letak perbedaan antar perlakuan satu dengan lainnya (Septiana dan Ardiaria, 2016 TOM (Total Organic Matter) merupakan seluruh bahan organik yang berasal dari detritus, fitoplankton atau hasil buangan biota lainnya yang diuraikan oleh mikroorganisme di sekitar perairan (Rustam et al, 2018). Kisaran kandungan TOM di perairan sungai Silugonggo pada bulan Desember 2019 adalah 8,22 -11,9 mg/L dengan rata-rata sebesar 11,23 mg/L dan kisaran TOM pada bulan Januari 2020 adalah sebesar 9,9 -11,69 dengan rata-rata sebesar 9,48 Gambar 1.…”

Pengukuran Parameter Bahan Organik Di Perairan Sungai Silugonggo, Kecamatan Juwana, Kabupaten Pati

2021

View full text Add to dashboard Cite

Perairan Silugonggo merupakan area pemukiman warga dengan banyak aktivitas perikanan dan kelautan seperti: pertambakan, industri perikanan dan merupakan alur pelayaran. Tingginya aktivitas pemukiman dan industri akan menghasilkan limbah organik dalam jumlah besar. Bahan organik yang melimpah dapat menimbulkan pencemaran lingkungan. Penelitian ini bertujuan untuk mengetahui kandungan bahan organik di perairan sungai Silugonggo, Kecamatan Juwana, Kabupaten Pati. Kandungan bahan organik diketahui melalui analisis parameter TOM (Total Organic Matter), BOD5 (Biochemical Oxygen Demand) dan COD (Chemical Oxygen Demand). Pengambilan sampel dilaksanakan pada tanggal 20 Desember 2019 dan 20 Januari 2020. Metode yang digunakan pada penelitian ini menggunakan metode kasus dengan pengamatan secara langsung di lapangan dan penentuan lokasi penelitian menggunakan metode purposive sampling. Hasil pengukuran parameter penelitian dianalisis menggunakan analisis ragam. Hasil penelitian menunjukkan bahwa nilai TOM sebesar 8,11 – 11,9 mg/L. Hasil pengukuran parameter (a) BOD5 sebesar 8,07 – 24,66 mg/L dan (b) COD sebesar 26,04 – 79,21 mg/L, hasil tersebut berada di bawah baku mutu yang ditetapkan menurut Keputusan Menteri Lingkungan Hidup No. 51 Tahun 2004 tentang Baku Mutu Air Limbah. Tingginya nilai TOM dikarenakan banyaknya masukan limbah bahan organik dari aktivitas di perairan sungai Silugonggo, seperti: pertambakan, industri perikanan, dan alur pelayaran. Silugonggo waters is a residential area with many fishery and marine activities such as: aquaculture, fishing industry and shipping lanes. High residential and industrial activities will produce large amounts of organic waste. Abundant organic matter can cause environmental pollution. This study aims to determine the content of organic matter in the waters of the Silugonggo River, Juwana District, Pati Regency. The content of organic matter is known through parameter analysis of TOM (Total Organic Matter), BOD5 (Biochemical Oxygen Demand) and COD (Chemical Oxygen Demand). Sampling was carried out on December 20, 2019 and January 20, 2020. The method used in this study used the method of direct observation in the field and the date of the research location using the purposive sampling method. The results of the measurement of research parameters were analyzed using analysis of variance. The results showed that the TOM value was 8.11–11.9 mg/L. Parameter measurement results (a) BOD5 of 8.07–24.66 mg/L and (b) COD of 26.04–79.21 mg/L, these results are below the quality standard stipulated according to the Decree of the Minister of the Environment No. 51 of 2004 concerning Wastewater Quality Standards. The high value of TOM is due to the large number of inputs of organic matter from activities in the waters of the Silugonggo river, such as: aquaculture, fishing industry, and shipping lanes.

“…Sedimen pasir sedikit mengandung bahan organik dikarenakan memiliki struktur butiran yang lebih besar dari jenis sedimen lanau, kerapatannya rendah, permeabilitas yang tinggi, dan mudah mengalami pencucian (akibat pasang surut), sehingga sulit untuk menyimpan bahan organik yang terlarut (Hakim et al, 2016). Bahan organik yang terlarut dalam perairan dengan proses fisika maupun kimia akan terendapkan di dasar perairan dan membentuk kandungan organik pada sedimen yang terdiri dari partikel-partikel hasil pecahan batuan dan potongan-potongan kulit serta sisa rangka organisme laut ataupun dari detritus organik daratan yang telah terangkut oleh air maupun angin dan terendapkan di dasar laut dalam kurun waktu yang cukup lama (Rustam et al, 2018). Hasil analisa sedimen dan bahan organik pada daerah penelitian terlihat pada Tabel 1. dan Gambar 3.…”
