"[ABSTRAKbr

Penelitian mengenai struktur komunitas diatom epifit pada daun lamun di padang lamun perairan Muara Binuangeun, Banten telah dilakukan pada tanggal 30 April -- 3 Mei 2015. Penelitian bertujuan untuk mengetahui struktur komunitas Diatom epifitik pada daun lamun Thalassia hemprichii (Ehrenb. ex Solms) Asch. antara lain, komposisi genus, kepadatan, dominansi, keanekaragaman, dan kemerataan pada setiap stasiun di Muara Binuangeun, Kabupaten Lebak, Banten. Penentuan lokasi pengambilan sampel dilakukan secara purposive sampling. Hasil penelitian menunjukan bahwa komposisi Diatom epifitik yang diperoleh di lokasi penelitian sebanyak 12 genus dari 4 kelas. Kepadatan Diatom epifitik tiap stasiun berkisar antara 91800 – 420560 sel/ dm2. Nilai indeks dominansi berkisar antara 0,617—0,917 dan tergolong tinggi di setiap stasiun, hal tersebut disebabkan karena terdapat genus Navicula yang mendominasi disetiap stasiun. Nilai indeks keanekaragaman di setiap stasiun penelitian tergolong rendah (berkisar antara 0,25—0,86). Nilai indeks kemerataan berkisar antara 0,1—0,36 dengan stasiun 1 dan 4 tergolong tidak merata, sedangkan pada stasiun 2 dan 3 tergolong kurang merata. Rendahnya nilai indeks keanekaragaman dan kemerataan disebabkan karena adanya tekanan ekologis pada lokasi penelitian. Secara umum, struktur komunitas Diatom epifitik pada lokasi penelitian tergolong tidak stabil karena tingkat dominansi yang tinggi, keanekaragaman yang rendah, dan kemerataan yang tidak merata dan kurang merata.

Struktur komunitas dan sebaran spasial bivalvia hubungannya dengan karakteristik lingkungan di Teluk Kotania, Seram Karat, Maluku Tengah

"Telah dilakukan penelitian mengenai struktur komunitas dan sebaran spasial Bivalvia serta hubungannya dengan karakteristik lingkungan di Teluk Katania, Seram Barat, Maluku Tengah. Ada 5 stasiun penelitian yaitu : Pelita Jaya 1, Pelita Jaya 2, Pulau Buntal, Pulau Tatumbu, dan Pulau Burung. Anadara maculafa merupakan jenis Bivalvia yang kepadatannya tertinggi (2,5 individu/m2). Nilai H' (indeks keanekaragaman) Bivalvia tertinggi ada di Pulau Burung (H' = 0,958) dan terendah di Pulau Buntal (H' = 0,624). Indeks kemerataan J' tertinggi (J' = 0,843) terdapat di Pelita Jaya 1. indeks kesamaan Morisita C tertinggi adalah antara Pelita Jaya 2 dan Pulau Buntal (C = 0,92). Kondisi substrat di Pelita Jaya 2 dan Pulau Buntal mempunyai persentase Lumpur yang tinggi. Dengan analisis cluster, 5 stasiun penelitian terbagi menjadi 2 kelompok. Kelompok I terdiri atas stasiun Pelita Jaya 2 dan Pulau Buntal kemudian kelompok II terdiri atas Pelita Jayal, Pulau Tatumbu, dan Pulau Burung. Analisis diskriminan dengan faktor lingkungan substrat pasir halus dan lumpur juga membagi kelima stasiun menjadi dua kelompok yang sama seperti pada analisis cluster. Substrat lumpur mempunyai kontribusi yang tinggi (96,3 %). Tellina sp merupakan jenis yang penyebarannya luas sebab selalu hadir di setiap stasiun penelitian. Hasil analisis faktorial koresponden membentuk enam kelompok. Penyebaran spasial jenis jenis Bivalvia di 5 stasiun dari hasil analisis tersebut berdasarkan pada kepadatan tertinggi dari jenis jenis tertentu (lima kelompok) dan berdasarkan jenis-jenis yang selalu hadir di setiap stasiun (satu kelompok).

Bivalvia, also known as Pelecypoda, is the second largest class in phylum Mollusca. This group has 28.000 species (Barth & Broshear, 1982) and about 1000 species of Bivalvia live in Indonesian waters (Nontji, 1987). Information about Bivalvia in Kotania Bay has not been known well. Based on those fact, a research on the community structure and spatial distribution of Bivalve in the waters of Kotania Bay was conducted in February 1996. The aim of study was to find out the relationship between Bivalvia community structure with environmental factors in the waters of Kotania Bay. The spatial distribution of Bivalvia in several small islands in Kotania Bay was also studied. Hopefully, the results can be used as basic information for father research.
The research was conducted in five stations, i.e. Pelita Jaya 1, Pelita Jaya 2, Buntal Island, Tatumbu Island, and Burung Island. The sampling method used in the study was belt transact. The water conditions measured were water temperature, salinity, and pH. The substrates were characterized by the sediment fractions. Temperatures in the research stations ranged between 29.5°C and 31 °C, the range of pH is between 7 and 8.4. Water salinities in the research stations varied between 22 % and 30 %. Substrates in the research stations mostly contained sand with the very high percentage of very coarse sand. Silt was the smallest fraction found in the substrate.
In five research stations, 32 species of Bivalvia belonging to 15 families were collected. Anadara maculata had the highest density (2.5 individulm2) of all Bivalvia species found. The highest H' value (diversity index) of Bivalvia was in Burung Island (H' = 0.958) and the lowest was in Buntal Island (H' = 0.624). The highest evenness index J' = 0.843 was found in Pelita Jaya 1. The highest similarity index was shown by Pelita Jaya 2 and Buntal Island. Substrates in Pelita Jaya 2 and Buntal Island were dominated by silt.
Cluster analysis at five research stations divided the stations into two groups. Group I, defined by Pelita Jaya 2 and Buntal Island. Group ii, defined by Pelita Jaya 1, Tatumbu Island, and Burung Island. Discriminant analysis based on two environmental factors, i.e. very fine sand and silts, also divided the stations into two similar groups as cluster analysis did. The silt factor had high contribution (96.3%) in separating the stations.
Factorial correspondence analysis classified the species of Bivalvia into six groups. Based on the highest density of the certain species (five groups) and on the common species found in all stations (one group). Among the species collected Tellina sp was the common species found in the five stations. Spondylus squamosus, Trachydarium subrugosum, and Vulsella vulsella were found only in Pelita Jaya 2. Pitar subpellucidus, Septifer hi/ocular-is, Fimbria fmbriata and Chama pacifica were found only in Burung island. The species of Bivalvia only found in Pelita Jaya 1 were Atrina vexillum, Tellina staurella, Chama ruderalis, Limaria fragilis, and Clycymeris pectunculus."

Respons burung terhadap efek tepi di kawasan Taman Nasional Bukit Barisan Selatan, Lampung = Edge responses on bird community in Bukit Barisan Selatan National Park, Lampung

"Studi mengenai respons burung terhadap efek tepi telah dilakukan pada tiga tipe habitat yaitu kawasan hutan, kawasan agrisilvikultur dan kawasan tepi Taman Nasional Bukit Barisan Selatan (TNBBS). Studi dilakukan pada bulan Agustus--September 2014 dan Maret--April 2015 di ketiga tipe habitat yang terletak di desa Sumberejo dan Pemerihan, Lampung Barat. Metode yang digunakan adalah point count dalam transek sejauh 1 km yang dibuat masing-masing ke arah hutan dan kebun dengan jarak antar titik yaitu 200 m. Hasil Cluster Analysis menghasilkan 8 kelompok dengan komposisi yang berbeda Secara umum, komunitas burung di TNBBS didominasi oleh spesialis tepi (ST). Sebanyak 30 jenis burung merespon positif terhadap keberadaan tepi dan didominasi oleh jenis dari suku Pycnonotidae. Namun, analisis berdasarkan tipe tepi menunjukkan bahwa komunitas burung TNBBS merespon negatif terhadap keberadaan jalan. Faktor vegetasi seperti komposisi vegetasi dan bukaan kanopi, serta tingkat intensitas gangguan diduga memengaruhi komposisi burung yang terdapat di kawasan tersebut. Struktur vegetasi yang lebih kompleks pada kawasan tepi berpotensi sebagai penyedia sumberdaya yang lebih beragam bagi komunitas burung. Namun, gangguan seperti aktivitas kendaraan dan perubahan lahan dapat berpengaruh terhadap ketidakhadiran jenis yang membutuhkan area yang lebih luas seperti Enggang gading dan Kuau raja. Kajian mengenai efek tepi terhadap burung diperlukan untuk menunjang manajemen konservasi biodiversitas di kawasan tepi TNBBS.

A study on bird community response to edge effect along the Bukit Barisan Selatan National Park (BBSNP) was conducted on August--September 2014 and March--April 2015 in three types of habitat: forest, agriculture and edge at Pemerihan and Sumberejo villages, West Lampung. The aim of the study was to determine the bird composition based on the habitat type and edge type. The bird survey was carried out using point count method in 1 km transect that established in both forest and agriculture area in those districts. Each transect composed of six point counts at 200 m intervals. By using Cluster Analysis, eight cluster represented each response of bird species to edge type and habitat type. The result showed, in general, edge area in BBSNP has the highest number of bird species than the other type of habitat. Thirty species was classified as edge species and dominated by species from Pycnonotidae. There were no number of birds in cluster which has high abundance in edge area with road as its edge type. The disturbance intensity and vegetation are the most important factors that affected the presence of bird in each habitat with different type of edge. Vegetation complexity along edge, as a combination between forest and agriculture, provides more resource for birds. Despite the benefit, the presence of road and habitat encroachment along the edge may probably responsible to the absence of forest-dependent species such as Helmeted hornbill and Great argus. More research on edge response on birds may support the better the management system of edge area around BBSNP, West Lampung."
