Abstract

ABSTRACTThe Leuweung Sancang Nature Reserve has ecosystem diversity, including seagrass beds, with a variaety of natural resources that are important to be preserved. Apart from being a food source for herbivorous organisms, seagrass beds also function as shelter and breed for many marine invertebrates, including Echinoderms. Association between Echinoderms and seagrass was observed in this study to investigate the interaction. Sampling was carried out in 1x1 m2 plots which were placed in 3  transect  lines  of 250 m long, with a plot intervals of 25 m on each transect line.  The transect line extended from the beach heading to the shore, and was carried out in 4 different stations, namely Ciporeang, Cipunaga, Cikolomberan, and Cipangikisan. Observation had been done to determine diversity, density, coverage, and evenness of both seagrass and Echinoderms, thus to study the correlation between them. The results showed that there were 2 seagrass species, Thalassia hempricii and Cymodocea rotundata, and there were 2 families of Echinoderms: Ophiocomidae and Holothuridae. Result of Rank–Spearman correlation coefficient showed possitive association between seagrass and echinoderms in all stations being observed, but only in Cikolomberan that showed significantly high association.Keywords:  association, Echinoderms, Leuweung Sancang, seagrass.ABSTRAKCagar alam Leuweung Sancang memiliki keanekaragaman ekosistem, termasuk padang lamun, dengan berbagai sumber daya alam di dalamnya yang penting untuk dijaga kelestariannya. Selain sebagai sumber makanan bagi organisme herbivor, padang lamun juga berfungsi sebagai tempat berlindung dan berkembang biak bagi banyak invertebrata laut, termasuk Echinodermata. Keterkaitan antara Echinodermata dan lamun diobservasi pada studi ini untuk dipelajari untuk melihat interaksinya. Pengambilan sampel dilakukan dalam plot 1 x 1 m2 yang ditempatkan pada 3 garis transek masing-masing sepanjang 250 m dengan interval plot sejauh 25 m pada setiap garis transek. Garis transek terbentang dari pantai menuju laut, dan dilakukan pada 4 stasiun yang berbeda, yaitu Ciporeang, Cipunaga, Cikolomberan, Cipangikisan. Pengamatan dilakukan untuk menentukan keragaman, kepadatan, frekuensi, tutupan dan kemerataan lamun dan Echinodermata, untuk kemudian dilihat asosiasinya. Hasil menunjukkan bahwa di keempat stasiun pengamatan ditemukan 2 spesies lamun yaitu Thalassia hempricii dan Cymodocea rotundata dan 2 famili Echinodermata: Ophiocomidae dan Holothuridae. Hasil koefisien korelasi Rank-Spearman pada keempat stasiun pengamatan menunjukan adanya asosiasi positif antara lamun dan Echinodermata, namun hanya di Cikolomberan yang memiliki asosiasi tinggi dan signifikan.Kata kunci: asosiasi, Echinodermata, Leuweung Sancang, lamun.

Abstract

ABSTRACTMaluku and Halmahera Sea are the entry paths for the Indonesian Throughflow (ITF). This study examined the variation of their current speed, current direction, and transport during the ENSO phases on La Nina in 2010-2011 and El Nino in 2015-2016. The data used were the Marine Copernicus reanalysis data of u and v components of current velocity at 155 m and 266 m of depth. The data were processed by using GrADS to see the direction and speed of the current as well as by calculating the ITF transport. During La Nina, both at 155 m and 266 m of depths were found the eddy patterns. When El Nino occurred, the direction of currents in Maluku Sea was different from La Nina conditions, while the direction of currents in Halmahera Sea had no differences. Current velocity in both oceans at each depth was lower during El Nino than La Nina. The condition of ITF transport in the Maluku Sea during La Nina was dominated by southward movement with a smaller value than during El Nino which generally moved northward meanwhile in the Halmahera Sea had the opposite condition.Keywords: current speed, current direction, ENSO, ITF, transport

ABSTRACT           Mangroves in Baluran National Park are one of the natural mangroves on Java Island. Habitat conditions strongly influence mangrove preservation, so any changes can affect species composition. Along with global climate change, it can  directly or indirectly impact on mangroves and their habitat. The purpose of this study was to determine the diversity of species and distribution patterns of mangroves. The research was conducted in mangroves located in SPTNW 1 Bekol Baluran National Park with an area of ± 288.7 ha with a sampling intensity of 0.5% to obtain 145 measuring plots. Data collections of mangrove vegetation use a combination of pathway and sampling plot methods which are placed systematically. Diversity analysis uses the Simpson index and distribution patterns with the dispersion index/variance-mean ratio. The measurements obtained 22 types of mangroves with 13 species at the seedling level, 19 species at the weaning level, and 21 species at the tree level. The highest density was at the seedling level (8,347.32 individuals/ha). The diversity of mangrove species at the seedling level is moderate, while weaning and trees are in the high category. The majority of mangrove species found have a clustered distribution pattern, with the dominant species being Ceriops tagal and Rhizophora apiculata. Keywords: Mangrove, distribution pattern, diversity, species composition, national parkABSTRAKTaman Nasional Baluran memiliki salah satu mangrove alami yang tersisa di Pulau Jawa.

ABSTRAKPenelitian ini bertujuan untuk mengetahui jenis logam-logam serta kadarnya di dalam sampel daging Kerang Darah (Anadara granosa) dan Kerang Bulu (Anadara antiquata) asal laut teluk Lewoleba kabupaten Lembata propinsi Nusa Tenggara Timur.  Kedua jenis kerang tersebut hidup di Pulau Siput (Awololong) yang ada di tengah kawasan laut Teluk Lewoleba.  Masyarakat Lembata menjadikan kedua jenis kerang tersebut sebagai lauk pauk serta sumber pendapatan ekonomi.   Perlu dilakukannya analisa cemaran logam berat di kawasan laut Teluk Lewoleba melalui kedua jenis kerang tersebut sebab aktivitas manusia telah semakin meningkat di kawasan teluk Lewoleba Lembata. Sebanyak 100 gram masing-masing sampel daging Kerang yang kering, didestruksi dan dianalisis kandungan unsur-unsur serta kadar unsur, menggunakan spektrofotometer X-ray Fluorescence (XRF). Hasil yang diperoleh yaitu sampel Kerang Darah mengandung unsur-unsur serta kadarnya yakni: P (10%), S (12%), K (12%), Ca (23%), Cr (0,32%), Fe (2,6%), Ni (0,2%), Cu (0,62%), Zn (20,6%), Br (3,4%), Mo (14%) dan Yb (0,9%). Sampel Kerang Buluh mengandung;  P (11,0%), S (1,0%), K (11,7%), Ca (39,2%), Cr (0,62%), Fe (8,95%), Ni (0,4%), Cu (0,49%), Zn (2,4%), Br (1,4%), Mo (22%) dan Yb (0,3%) dan Re (0,5%). Tampak kedua jenis sampel mengandung logam berat esensial berupa Cu, Fe, Zn dan Ni, serta mengadung Cr yang bersifat toksik.  Kadar Cr pada sampel Kerang Buluh lebih tinggi dari Kerang Darah.  Sampel Kerang Buluh mengandung pula unsur Re yang merupakan jenis unsur tanah jarang. Kadar logam berat Cu, Ni dan Cr pada kedua sampel melampaui ambang batas menurut Keputusan Mentri Lingkungan Hidup Republik Indonesia nomor 51 tahun 2004Kata Kunci: daging kerang, logam berat, laut teluk LewolebaABSTRACTThis study aims to determine the types of metals and their levels in the samples of Blood Clams (Anadara granosa) and Feather Shells (Anadara antiquata) from the sea of Lewoleba Bay, Lembata district, East Nusa Tenggara province. Both types of shellfish live on Slug Island (Awololong) in the middle of the Lewoleba Bay marine area. The people of Lembata use the two types of shellfish as side dishes and a source of economic income. It is necessary to analyze heavy metal contamination in the marine area of Lewoleba Bay through these two types of shells because human activities have been increasing in the Lewoleba Bay area of Lembata. A total of 100 grams of each sample of dried mussel meat, was destroyed and analyzed for the content of elements and levels of elements, using an X-ray Fluorescence (XRF) spectrophotometer. The results obtained were that the Blood Shellfish sample contained the following elements and levels: P (10%), S (12%), K (12%), Ca (23%), Cr (0.32%), Fe (2 .6%), Ni (0.2%), Cu (0.62%), Zn (20.6%), Br (3.4%), Mo (14%) and Yb (0.9%) . Reed Shells samples contain; P (11.0%), S (1.0%), K (11.7%), Ca (39.2%), Cr (0.62%), Fe (8.95%), Ni ( 0.4%), Cu (0.49%), Zn (2.4%), Br (1.4%), Mo (22%) and Yb (0.3%) and Re (0.5% ). It appears that both types of samples contain essential heavy metals in the form of Cu, Fe, Zn and Ni, and contain Cr which is toxic. The Cr content in the Reed Shells samples was higher than that of Blood Clams. The Reed Shells sample also contains the element Re which is a type of rare earth element. Heavy metal levels of Cu, Ni and Cr in both samples exceeded the threshold according to the Decree of the Minister of the Environment of the Republic of Indonesia number 51 of 2004.

Abstract

ABSTRAKSebagian wilayah pesisir Kabupaten Pandeglang di Provinsi Banten merupakan kawasan berkembang dengan tingkat aktivitas manusia berupa kegiatan industri dan pariwisata yang cukup tinggi. Pengamatan dan pengelolaan dinamika wilayah kepesisiran terutama daerah pantai menjadi kajian penting dalam menunjang keberlangsungan masyarakat di wilayah pesisir. Perubahan garis pantai dapat diidentifikasi menggunakan teknologi penginderaan jauh, Sistem Informasi Geografis (SIG) dan analisis statistik. Analisis laju perubahan garis pantai dilakukan dengan menggunakan perangkat lunak Digital Shoreline Analysis System (DSAS). Metode statistik yang digunakan yaitu Net Shoreline Movement (NSM) dan End Point Rate (EPR). Secara umum, garis pantai di sebagian wilayah pesisir Pandeglang mengalami akresi dan erosi. Akresi terjauh ditunjukkan pada area sekitar Pelabuhan PLTU Labuan sejauh 696,48 meter dengan laju perubahan sebesar 19,88 meter/tahun. Hal ini mengindikasikan reklamasi lahan merupakan salah satu faktor yang menginduksi terjadinya proses akresi pada area tersebut. Sedangkan erosi terbesar terjadi di Tanjung Lesung sejauh -135,08 meter dengan laju perubahan -4,50 meter/tahun.Kata kunci: garis pantai, DSAS, dinamika kepesisiran, Pandeglang, Banten.ABSTRACTPart of the coastal area of Pandeglang Regency in Banten Province is a developing area with a high level of human activity in the form of industrial and tourism activities. Observation and management of the dynamics of coastal areas, especially related to the shoreline, are important studies in supporting the sustainability of communities in coastal areas. Shoreline changes can be identified using remote sensing technology, Geographical Information Systems (GIS), and statistical analysis. Analysis of the shoreline rate was carried out using the Digital Shoreline Analysis System (DSAS) software. The statistical methods used are Net Shoreline Movement (NSM) and End Point Rate (EPR). In general, the shoreline in some coastal areas of Pandeglang experiences accretion and erosion. The farthest accretion is shown in the area around PLTU Labuan Port as far as 696.48 meters with a change rate of 19.88 meters/year. This indicates that land reclamation is one of the factors that induce the accretion process in the area. Meanwhile, the largest erosion occurred in Tanjung Lesung as far as -135.08 meters with a rate of change of -4.50 meters/year.Keywords: shoreline, DSAS, coastal dynamics, Pandeglang, Banten.
