Abstract

Macrozoobenthos are organisms that live by crawling, sticking, burrowing, and burrowing both at the bottom of the water and on the surface of the water bottom. Macrozoobenthos that live in mangrove areas mostly live on hard sediments to mud. The existence of macrozoobenthos can be influenced by various environmental factors such as the physical, chemical, and biological properties of water. This research aims to determine diversity, uniformity, and the macrozoobenthos dominance of the mangrove ecosystem in Bagan Asahan Village. The method used in this research is to combine two methods, namely the square method and the line transect method. The quadratic method is used to see the macrozoobenthos found in the quadratic method in a biological system, while the line transect method is used as a point to determine the description of the macrozoobenthos. The results of the research show that there are 8 species of macrozoobenthos consisting of 3 classes with a total of 179 individuals. The diversity of macrozoobenthos in the mangrove ecosystem area in Bagan Asahan Village is classified as moderate with a diversity index H'' ranging from 1.54-2.01, the uniformity index is classified as stable ranging between E= 0.76-0.99 and the dominance index is low, ranging between C= 0.14-0.31.

This research aims to determine the levels of heavy metals lead (Pb), iron (Fe), and zinc (Zn) in the Bah Bolon River water, Pematangsiantar City. This research was conducted in August-September 2023. Water samples were collected by selecting 3 research stations with 3 repetitions. Then the heavy metal content of the samples was analyzed using the Atomic Absorption Spectrophotometry (SSA) method. The results of this study show that the levels of the heavy metal iron (Fe) are higher than the heavy metals (Pb) and (Zn). The test results for iron (Fe) at all stations ranged from 0.08-0.51 mg/L, lead (Pb ) of 0.003 mg/L, zinc (Zn) ranges from 0.001 mg/L, temperature ranges from 25.06-26.9 oC, pH ranges from 7.18-7.61, DO ranges from 6.33-7.2 mg/L The quality of Bah Bolon river waters based on PPRI No.22 of 2021 for the parameters of lead (Pb), zinc (Zn), iron (stations 2 and 3), pH, DO, and temperature still meets class 2 quality standards and is suitable for use. used as a source of irrigation or agricultural water and the iron (Fe) content at station 1 has exceeded the quality standard limit and is no longer suitable for use.

Abstract

Aquatic plants are part of the vegetation of these inhabitants in the earth, whose growth medium is water. The existence of aquatic plants that live well will increase aquatic productivity, and the role of aquatic plants is very important as a primary producer, as a habitat for biota such as fish, fish shelters, places to attach various animals and plants or algae. Transect method used is line transect with Quadrant 1 x 1 m. Data analysis includes diversity index, uniformity index and dominance index. Physical-chemical parameters include temperature, pH, dissolved oxygen and light intensity. The results found 3 species of aquatic plants Macrophytes vallisneria gigantea, Potamogeton crispus, and Myriophyllum spicatum. Diversity of aquatic plants macrophytes in coastal waters Aek Batu Tambun Raya District Pematang Sidamanik Simalungun classified as low with diversity index H' = 0.420-0.812 overall uniformity value of E = 0.5125 which falls into the category of labile, and the overall dominance of 0.7088 which is included in the medium category. Keywords:  aquatic plants macrophytes, diversity, uniformity, dominance. Abstrak Tumbuhan air merupakan bagian dari vegetasi penghuni bumi ini, yang media tumbuhnya adalah perairan. Keberadaan tumbuhan  air yang hidup dengan baik akan meningkatkan produktivitas perairan, dan peranan tumbuhan  air yang sangat penting adalah sebagai produsen primer, sebagai habitat biota seperti ikan, tempat perlindungan ikan, tempat menempel berbagai hewan dan tumbuhan  atau alga. Metode transek yang dipakai yaitu transek garis (line transect) dengan kuadran 1 x 1 m. Analisis data meliputi indeks keanekaragaman, indeks keseragaman dan indeks dominansi. Parameter fisik kimia meliputi suhu, pH, oksigen terlarut dan intensitas cahaya.

Abstract

Research on the distribution of TSS and containing water chlorophyll-a using GEE Cloud Technology in Jakarta Bay Waters was conducted from April to August 2021. Analysis was carried out using the MODIS AQUA-L3SMI satellite and Sentinel 2 TOA reflectance data. The TSS results show that it is distributed evenly (homogenously), varies, and fluctuates from the coast of Jakarta to the Waters of Jakarta Bay, namely 0-120 mg/l, while the containing water chlorophyll-a is distributed unevenly or varies, namely from April 2021 with value 0-3 mg/m3, chlorophyll-a in May 2021 almost evenly distributed with a value of 0-2 mg/m3, chlorophyll-a in June 2021 spread unevenly and fluctuating with an amount of 1-3  mg/m3, for chlorophyll-a in July 2021 was absent due to the influence of many and thick clouds. Chlorophyll-a in August 2021 spread almost evenly and varied throughout the waters amounting to 0,28 mg/m3. TSS spreads evenly (homogeneously), varies, and fluctuates around the edge of Jakarta's coastal waters down to the waters of Jakarta Bay and is not suitable for demersal fish species except zooxanthellae coral reef species. Meanwhile, the containing water chlorophyll-a is spread evenly, varies, and fluctuates. The large amount of chlorophyll-a in all waters and the high TSS will cause total death of living creatures in the waters. Image data can be used to map TSS distribution patterns and contain water chlorophyll-a in the waters of Jakarta Bay. Keywords: TSS; Containing Water Chlorophyll-a; MODIS AQUA-L3SMI Satellite; Sentinel 2 TOA reflectance data Satellite; Jakarta Bay Waters. Abstrak Penelitian sebaran TSS dan kandungan klorofil-a menggunakan Teknologi GEE Cloud di Perairan Teluk Jakarta telah dilaksanakan dari bulan April sampai dengan Agustus 2021. Analisis dilakukan dengan menggunakan satelit MODIS AQUA-L3SMI dan Sentinel 2 TOA reflectance data. Hasil TSS diperoleh bahwa menyebar merata (homogen), bervariasi, dan berfluktuasi dari pinggir pantai Jakarta sampai ke arah perairan Teluk Jakarta, yaitu 0-120 mg/l, sedangkan kandungan klorofil-a menyebar tidak merata atau bervariasi, yaitu dari bulan April 2021 dengan nilai 0-3 mg/m3, klorofil-a di bulan Mei 2021 hampir menyebar merata yang nilai 0-2 mg/m3, klorofil-a di bulan Juni 2021 menyebar tidak merata dan berfluktuasi dengan jumlah 1-3 mg/m3, untuk klorofil-a di bulan Juli 2021 tidak ada karena pengaruh awan yang banyak dan tebal, dan klorofil- a di bulan Agustus 2021 menyebar hampir merata dan bervariasi ke seluruh perairan berjumlah 0-2,8 mg/m3. TSS menyebar secara merata (homogen), bervariasi dan fluktuasi di sekitar pinggiran perairan pantai Jakarta sampai ke perairan Teluk Jakarta dan tidak cocok untuk jenis-jenis ikan demersal kecuali jenis terumbu karang zooxanthellae. Sedangkan kandungan klorofil-a nya menyebar secara merata, bervariasi dan fluktuasi. Banyaknya kandungan klorofil-a yang ada di semua perairan dan TSS nya tinggi, akan menyebabkan kematian secara total terhadap makhluk hidup di dalam perairan. Data citra dapat digunakan untuk memetakan pola sebaran TSS dan kandungan klorofil-a di wilayah perairan Teluk Jakarta.
