Abstract

Perairan Pantai Tanah Merah dan Perairan Pulau Semujur, ke dua lokasi tersebut terletak di Kabupaten Bangka Tengah. Secara Geografis yang membedakan ke dua lokasi tersebut adalah, lokasi yang satu berada di daratan pantai (Tanah Merah) cukup jauh dari pemukiman penduduk, sedangkan lokasi yang lain berada di lingkungan perairan Pulau Kecil (Semujur), yang berpenduduk. Kondisi geografis yang berbeda tersebut dapat menyebabkan  kandungan unsur hara nitrat tentu akan berbeda, karena sumber unsur hara nitrat yang utama berasal dari kegiatan manusia di darat. Tingginya unsur hara Nitrat akan berpengaruh terhadap kelimpahan fitoplankton di perairan setempat. Penelitian ini bertujuan untuk mengetahui konsentrasi dan sebaran nitrat dalam kaitannya dengan kelimpahan fitoplankton di laut. Penelitian dilakukan di perairan pantai Tanah Merah dan perairan Pulau Semujur, Kebupaten Bangka Tengah. Penelitian dilakukan pada bulan Februari sampai April 2020. Hasil penelitian menunjukkan bahwa kandungan nitrat di perairan pantai Tanah Merah sebesar 0.011-0.026 mg/L (St.1-St.4) lebih rendah dibandingkan dengan perairan Pulau Semujur sebesar 0.046-0.10 mg/L (St.9-St.12). Data kelimpahan fitoplankton dan Indeks Keanekaragaman Jenis (H’) menunjukkan bahwa perairan pantai Tanah Merah sebesar 111.000-134.000 sel/L dan indeks H’ sebesar 2.06 - 2.16 lebih rendah dibandingkan dengan data kelimpahan fitoplankton di perairan Pulau Semujur sebesar 110.000-208.000 sel/L dan indeks H’ sebesar 2.22-2.29. Data pendukung berupa kecepatan arus di perairan pantai Tanah Merah berkisar antara 0.14-0.21 m/d lebih rendah dibandingkan dengan perairan pulau Semujur sebesar 0.22-0.32 m/d.

Abstract

Nautilus is the only surviving genus whose members were numerous and widely dispersed in the oceans throughout the Jurassic and Miocene times. It represents the only living member from the Family Nautilidae and is often considered as a living fossil. Nautilus is found with high biodiversity in Ambon, Indonesia, and were in special cases even found in Bangka Belitung, far from their original habitat. This study aimed to understand the historical component of the habitat and distribution of Nautilus in Bangka Belitung and to determine the depth, temperature, current, and environmental heterogeneity relate to Nautilus. Nautilus samples were found in Bangka Belitung Seas nearby a crack region at 50–75 m deep while the optimal depth of the Nautilus was 150–300 m, depending on the local area. The locations in the Bangka Belitung Seas where Nautilus found have sea surface temperatures between 30-31°C and 27-28°C during the East Monsoon and the West Monsoon respectivelly. The implications of temperature as a limiting factor are fairly significant, as it restricts the upper limit of the living habitat to predictable depths, which vary both geographically and seasonally during the West Monsoon when surface temperatures approach habitable levels. Sea currents at the Bangka Belitung Seas move at 0–0.6 m.s-1 during the East Monsoon and speed up near the North Natuna Sea. During the West Monsoon, currents predominantly flow from the Natuna Sea to the Java Sea at 0–0.5 m.s-1. Large-scale deep-water currents and the effects of smaller currents on scent dispersal influence the directional movements of Nautilus.

Abstract

Banyaknya aktivitas penambangan timah di Bangka Belitung menyebabkan pencemar logam berat terakumulasi ke badan perairan, salah satunya adalah kegiatan penambangan timah di perairan Tanah Merah. Penelitian dilaksanakan pada bulan April - November 2019 di Pantai Tanah Merah Kabupaten Bangka Tengah. Tujuan penelitian ini yaitu mengetahui konsentrasi polutan logam berat (Pb dan Cu) di perairan tersebut. Metode penelitian dilakukan dengan cara purposive sampling dan melakukan analisis logam berat (Pb dan Cu) serta pemodelan menggunakan MIKE21 untuk mengetahui persebarannya. Hasil menunjukkan bahwa model sebaran polutan logam berat sangat dipengaruhi oleh kondisi arus yang dominan berupa arus pasang surut. Model sebaran Pb dan Cu di perairan terkonsentrasi di area sumber pencemar yang telah berada di atas baku mutu air laut dan semakin kecil menjauhi sumber lokasi pertambangan sesuai dengan arah arus perairan. Pemodelan menunjukkan bahwa jarak sebaran terjauh dan arah dari polutan logam berat (Pb dan Cu) di perairan, masing-masing sebesar 7,51 mil (12.086 meter); 6,17 mil (9.929 meter) dengan waktu tempuh 68 dan 62 hari dan arah polutan 330oU. Pola sebaran logam berat yang sangat luas ini mengindikasikan bahwa aktifitas pertambangan tidak direkomendasikan pada lokasi yang berdekatan dengan fishing ground  karena efek sebaran logam berat yang berbahaya akan terakumulasi pada biota bahkan ekosistem perairan.

Abstract

Matras waters receive input of pollutants from tin mining activities. Heavy metals are toxic and carcinogenic to aquatic biota. Sediment is a carrier of heavy metal pollutants and can act as a “sink” and a “source”. Heavy metals in sediments can reflect the condition/quality of the aquatic system. The purpose of this study was to examine the contamination and ecological risk of heavy metals Cd, Pb, Cu, and Zn in the sediments of Matras waters, Sungailiat, Bangka Regency. Heavy metal test using atomic absorption spectrophotometer (AAS). The concentrations of heavy metals Cd, Pb, Cu, and Zn obtained ranged from 0.02-0.06 mg/kg (average 0.04 mg/kg), 0.12-0.18 mg/kg (mean- average 0.15 mg/kg), each station 0.01 mg/kg (mean 0.01 mg/kg), and 0.54-1.34 mg/kg (mean 0.92 mg/kg ). CF, I-Geo, PLI, and RI values for Cd, Pb, Cu, and Zn metals obtained in Matras water sediments showed low contamination levels (CF<1), not polluted (Igeo 0), not polluted (PLI < 1), and low ecological risk (RI < 150). The EF value obtained indicates the heavy metals Cd, Pb, Cu, and Zn in the Matras waters mainly receiving input from anthropogenic sources (EF value> 1.5). The low ecological risk status which is reinforced by the low values of CF, I-Geo, and PLI indicates that the negative potential of metals to biota is also low.  Perairan Matras menerima masukan bahan pencemar dari aktivitas penambangan timah. Logam berat bersifat toksik dan karsinogenik terhadap biota akuatik. Sedimen merupakan pembawa polutan logam berat dan dapat berperan sebagai “sink” and “source”. Logam berat pada sedimen dapat merefleksikan kondisi/ kualitas sistem akuatik. Tujuan penelitian ini untuk mengkaji kontaminasi dan resiko ekologi logam berat Cd, Pb, Cu, dan Zn pada sedimen Perairan Matras, Sungailiat, Kabupaten Bangka. Uji logam berat menggunakan metode spektrofotometer serapan atom (SSA). Konsentrasi logam berat Cd, Pb, Cu, dan Zn yang diperoleh berkisar antara 0,02-0,06 mg/kg (rata-rata 0,04 mg/kg), 0,12-0,18 mg/kg (rata-rata 0,15 mg/kg), setiap stasiun 0,01 mg/kg (rata-rata 0,01 mg/kg), dan 0,54-1,34 mg/kg (rata-rata 0,92 mg/kg). Nilai CF, I-Geo, PLI, dan RI untuk logam Cd, Pb, Cu, dan Zn yang diperoleh pada sedimen Perairan Matras menunjukkan tingkat kontaminasi rendah (CF<1), tidak tercemar (Igeo 0), tidak tercemar (PLI <1), dan resiko ekologi rendah (RI < 150). Nilai EF yang diperoleh mengindikasikan logam berat Cd, Pb, Cu, dan Zn perairan Matras utamanya mendapat masukan dari sumber antropogenik (nilai EF>1,5). Rendahnya status resiko ekologi yang diperkuat dengan rendahnya nilai CF, I-Geo, dan PLI menunjukkan potensi negatif logam terhadap biota juga rendah.

Abstract

The Baturusa River watershed has mining, fishing, industrial, and ship berthing activities. Activities carried out either directly or indirectly in the river can trigger the potential for pollution. Heavy metals are hazardous pollutants which, if present in large quantities, affect various aspects of the waters, both biologically and ecologically. The aim of this study was to determine the concentration of heavy metals Pb and Cd as well as the level of metal contamination of Pb and Cd (CF/ contamination factor, I-Geo/ Geoaccumulation Index) EF/ Enrichment factor) in the sediments of the Baturusa River Estuary, Pangkalpinang City. Heavy metals were analyzed by the AAS method. The concentration of Pb and Cd in the Baturusa River Estuary sediment has not exceeded the limit range based on the quality standards specified in the ISQG and PEL CCME 2002. The value of the heavy metal contamination factor (CF) of Pb found in the Baturusa Estuary sediment ranged from 0.00029–0.00042 ( CF

Abstract

The waters of Tanah Merah beach waters and Semujur Islands waters are both located in Bangka Tengah Regency. Geographically it can be indicated Tanah Merah is quite far from residential areas, while the other locations are in the inhabited small island waters (Semujur). These different geographical conditions can cause the content of nitrate nutrients to be different because the main source of nitrate nutrients comes from human activities. High nitrate nutrients will affect the abundance of phytoplankton in local waters. This study aims to determine the value and nitrate in relation to the abundance of phytoplankton in the sea. Moreover this research was applied in Tanah Merah beaches waters and Semujur Island waters, Bangka Tengah Regency, from February to April 2020. The results shown that the nitrate content in Tanah Merah beaches waters was 0.011-0.026 mg/LT (St.1-St.4) which was lower compared of 0.046-0.10 mg/L (St.9-St.12) at Semujur Island waters. Phytoplankton abundance data and Species Diversity Index (H ') show that the Tanah Merah beaches waters are 111,000-134,000 cells/L and the H' index is 2.06-2.16 lower than the phytoplankton abundance data in Semujur Island waters of 110,000 - 208,000 cells/L and the H 'index of 2.22-2.29. Others evident to support that data are the current velocity in Tanah Merah beaches waters ranges from 0.014-0.21 m/s less than Semujur Island waters at 0.22-0.32 m/s.

Abstract

Remote sensing techniques by utilizing satellite imagery can provide many advantagesin assessing information about the distribution of seagrass ecosystem in the Panjang Island waters. By using Sentinel 2A satellite imagery with a spatial resolution of 10 m, this study will provide information about the condition of seagrass beds in Panjang Island. The next step is the application of the Depth Invariant Index (DII) algorithm or the water column correction with the Lyzenga algorithm on the image. Based on the results of the supervised classification in ENVI 5.2 software, the color hue of each class shows a different color. There are six classes, namely land, seagrass, rubble / coral fragments, reef coral, sand and sea. The area of seagrass has an area of about 70.24 ha. There are 7 types of seagrass found in the waters of Panjang Island. Among them are, Enhalus acoroides, Thalassia hemprichii, Cymodocea rotundata, Halophila ovalis, Halodule uninervis, Syringodium isoetifolium, and Halodule pinifolia. The percentage of seagrass cover based on the results of the field survey has an average of 9.84% which is categorized as poor/damaged. The lowest percentage with a value of 3.48% is at station 3 and the highest with a value of 12.91% is at station 2.
