Abstract

Perairan Teluk Ciletuh berada pada ambang batas pencemaran. Pemantauan pencemaran dan kualitas perairan dapat diketahui melalui parameter Total Suspended Solid (TSS) dan Klorofil-a. Klorofil-a dapat dijadikan indikator tingkat kesuburan perairan dan TSS  merupakan salah satu parameter penentu kualitas air. Metode penginderaan jauh digunakan untuk menestimasi konsentrasi klorofil, TSS, Algae Bloom dan pemetaan distribusinya di laut. Data yang digunakan dalam penelitian ini adalah data citra satelit Landsat 7 dan Landsat 8 pada tahun 1999, 2000, 2012, 2022, dan 2023. Kesimpulan dari penelitian ini bahwa konsentrasi klorofil-A cenderung meningkat seiring pertambahan usia tambak udang dalam dua dekade terakhir di semua stasiun pengamatan, disebabkan oleh peningkatan kandungan nutrien akibat aktivitas manusia. Meskipun demikian, nilai klorofil-A ini tetap berada dalam kategori cukup (oligotrofik) dan sedang (mesotrofik) menandakan tida adanya pencemaran berat. Sementara itu, visualisasi algae bloom menggunakan SABI tidak menunjukkan keberadaan algae blooming. Konsentrasi TSS menunjukkan nilai-nilai yang masih dalam batas baku mutu perairan untuk ekosistem mangrove.

Abstract

ulau Harapan merupakan salah satu wilayah di Kepulauan Seribu yang melakukan rehabilitasi mangrove dengan jenis Rhizophora stylosa sejak tahun 2005. Tetapi, pertumbuhan diameter batang mangrove yang cenderung lambat menjadikan rehabilitasinya tidak optimal. Tujuan dilaksanakannya riset ini adalah untuk menganalisis faktor lingkungan yang memengaruhi kondisi mangrove hasil rehabilitasi di Pulau Harapan. Metode yang digunakan yakni survei lapangan untuk mendapatkan data kondisi mangrove, data faktor lingkungan berupa suhu, salinitas, pH, DO, nitrat, fosfat, serta jenis substrat dari ekosistem mangrove. Untuk mengetahui keterkaitan kondisi mangrove dengan faktor lingkungan, dilakukan Principal Component Analysis. Terdapat 3 stasiun pengamatan pada penelitian yang ditentukan menggunakan metode purposive sampling dengan pertimbangan utama berupa perbedaan kondisi lingkungan. Hasil penelitian menunjukkan bahwa mangrove hasil rehabilitasi di Pulau Harapan berada dalam kondisi baik dan sangat padat. Tetapi, jarak penanaman yang terlalu dekat serta tidak dilakukannya penjarangan saat mangrove mulai tumbuh besar menyebabkan ketidakcukupan ruang untuk mangrove dapat tumbuh dengan baik. Kondisi mangrove di Pulau Harapan yang berupa kerapatan dan pertumbuhan, utamanya dipengaruhi oleh substrat pada ekosistem mangrove yang kasar serta kandungan nutrien dengan konsentrasi yang cukup tinggi, dimana konsentrasi fosfat berkisar 0,038 – 0,062 mg/L dan konsentrasi nitrat berkisar 0,059 – 0,461 mg/L. Selain itu, faktor lingkungan lain seperti nilai pH yang berada di bawah baku mutu yang telah ditetapkan serta kondisi perairan Pulau Harapan yang termasuk dalam kategori tercemar ringan turut berpengaruh pada kondisi mangrove. Harapan Island is one of the areas in the Thousand Islands that has been rehabilitating mangroves with the type Rhizophora stylosa since 2005. However, the slow growth of mangrove trunk diameter makes the rehabilitation not optimal. The purpose of this research is to analyze environmental factors that affect the condition of rehabilitated mangroves on Harapan Island. The method used is a field survey to obtain data on mangrove conditions, environmental factor data in the form of temperature, salinity, pH, DO, nitrate, phosphate, and substrate types from mangrove ecosystems. To determine the relationship between mangrove conditions and environmental factors, a Principal Component Analysis was conducted. There are 3 observation stations in the study that are determined using the purposive sampling method with the main consideration being differences in environmental conditions. The results of the study show that the rehabilitated mangroves on Harapan Island are in good condition and very dense. However, the planting distance that is too close and the lack of thinning when the mangroves begin to grow large causes insufficient space for mangroves to grow properly. The condition of mangroves on Harapan Island, which is in the form of density and growth, is mainly influenced by the substrate in the mangrove ecosystem which is rough and the nutrient content with a fairly high concentration, where the phosphate concentration ranges from 0.038 – 0.062 mg/L and the nitrate concentration ranges from 0.059 – 0.461 mg/L. In addition, other environmental factors such as pH values that are below the predetermined quality standards and the condition of the waters of Harapan Island which are included in the lightly polluted category also affects the condition of mangroves.

Abstract

Environmental conditions that are quite important in the growth of mangroves are the type of sediment, organic matter, and water quality because the organic matter produced can be useful for mangrove fertility. This study aims to determine the type of sediment, the percentage of total organic matter, water quality, mangrove density, and determine the relationship between sediment types, total organic matter, and water quality on mangrove density on Tunda Island, Serang, Banten. This study used a survey method while collecting data using a purposive sampling method. Mangrove density was obtained through the line transect plot method. The sediment type test used the dry sieving method, the total organic matter (BOT) test used the loss on ignition (LOI) method, the statistical test used the multiple correlation method. All data was then analyzed in a quantitative descriptive manner. The results of the study are that the type of sediment in Tunda Island mangroves is dominated by silty sand and sand. The total organic matter contained in mangrove sediments ranges from 2.40% - 3.62% which is included in the moderate to high category. Salinity values ranged from 31 - 34.33 ppt included in the high category. The pH value ranges from 7.33 - 7.70 which is included in the good category for mangrove growth. Temperature values ranging from 27.37oC - 31.63oC are included in the good category for mangrove growth because they can still grow and develop normally. The mangrove density level is dominated by the dense category, which is 2,400 ind/Ha at station 1 and 1,700 ind/Ha at station 2, and the rare category is 1,000 ind/Ha at station 3 and 900 ind/Ha at station 4. There is a significant relationship between sediment type, total organic matter, water quality with mangrove density.Keywords: BOT; Mangroves; Sediment; Water Quality

Abstract

This research was carried out in Pangandaran Regency, specifically in the Batukaras, Nusawiru, and Bojongsalawe areas, in March-April 2022. This research to determine the characteristics of Avicennia type mangroves, habitat characteristics, and the ability of Avicennia type mangrove roots to trap debris. The method used is the Line Transect (LT) method. The results obtained from research on the characteristics of this type of Avicennia mangrove include that the circumference of mangrove roots ranges from 2-24 cm, the height of mangrove roots ranges from 3-83 cm, and the number of mangrove roots ranges from 925-2988 roots. The wider the area, the more debris you will find. Based on the results of the calculation of the characteristics of the Avicennia-type mangrove habitat in Pangandaran, it is in a good range. The calculations include salinity in the range of 15-22 ppt, a temperature of 32-34 °C, a pH value of 7,6-8, and DO (dissolved oxygen) of 4-4,5 mg/L. The trapping of waste in the Avicennia root area is categorized as strong. So the denser the mangrove roots are, the density of debris will increase. This is proven by the large amount of debris found in Batukaras.Keywords: Avicennia mangrove; Characteristics, Category, Density, Marine debris; Type.

Abstract

Microplastics are small plastics (<5 mm) that are difficult to decompose, thus making this material last for a long time. This causes serious problems, especially in the waters. This study aims to quantitatively analyze the sediments found at the bottom of the waters and the types of microplastics as well as the factors that influence their presence in the seabed sediments of Untung Jawa Island, Seribu Islands. The method used is descriptive and observation, wherefrom these methods are determined 4 sampling stations with a depth of 15.4 – 23 m sediment sampling. The result of this research is that the most commonly found microplastics are fragments. The total number of microplastics found was 1324 microplastic particles with characteristic sizes ranging from 15-900µm and various colors. The highest abundance that dominates the number of microplastics based on their size is in the <250 m category with a percentage of 47%. Meanwhile, in the 250 m size category, the frequency was 36% of the total number of microplastics found, then 13% for the 500 m size category, and the remaining 4% frequency for the >750 m size category was found. The results showed that the gravel sand sediment had the highest number of microplastics compared to other sediments. Based on descriptive observations of current data, it is known that there is a relationship between currents and the distribution of microplastics at the research station.
