Judul: Struktur dan Sebaran Komunitas Bulu Babi (Echinoidea) di Habitat Lamun Pulau Sapudi, Kabupaten Sumenep, Madura
Abstrak: Sea urchins dispersed from intertidal zone to subtidal zone. Sea urchins are generally inhabit coral reefs, seagrass beds and also prefer almost hard substrate of seagrass beds consisting of sand and rubble. This research objectives is to study the structure and distribution of sea urchins communities in seagrass beds of Sapudi island and it’s relationship with characteristic of habitat. Observation of research location is conducted from June, 28th until 29th Sea urchins species were found in this research are Echinotrix calamaris, Diadema setosum, Diadema savignyi, Echinotrix diadema, Echinometra mathaei, Tripneustes gratilla, Mespilia globulus, and Temnopleurus alexandri. Sea urchins density on each stations dominated by Diadema setosum and Echinometra mathaei. Seagrass species were found in this research are Thalassia hemprichii, Enhalus acoroides, Halophila ovalis, Syringodium isoetifolium, and Cymodoceae rotundata. Seagrasses density on each stations dominated by Thalassia hemprichii, Enhalus acoroides and Cymodocea rotundata, while percent cover of seagrass dominated by Thalassia hemprichii, Cymodocea rotundata, and Syringodium isoetifolium. 2012. Primary data was collected at research location from June 30th until July 3th 2012, in four stations. Station 1 is located in south of the island (Banasem village), station 2 in west (Soka Rammi village), station 3 in north (Sonok village), and station 4 in east (Prambanan village). There are 3 line transects on each station. Each line trancents along 50 meters were laid perpendicular towards the beach. The distance between line transect are 20 meters. Furthermore, there are 5 plot transects sized 1m x 1 m on each line transect, with a distance of 10 meters between 3 line transects. Collected data are sea urchins density, seagrass density, percent cover of seagrass, water quality parameters, and substrate samples. The distribution pattern of sea urchins in Sapudi island, Madura is categorized as clumped distribution (Id>1). Correspondent analysis shows the relationship between the distribution of sea urchins and seagrass is centered on Factorial axis 1 (F1) an factorial axis 2 (F2). The data shows that the distribution of Mespilia globulus and Echinotrix calamaris is associated with Enhalus acoroides and Syringodium isoetifolium, while the species of Diadema setosum, Diadema savignyi, and Echinotrix diadema is associated with Thalassia hemprichii.

Judul: Struktur dan Sebaran Echinoidea di Padang Lamun Perairan Kelurahan Pulau Panggang, Kepulauan Seribu, DKI JAkarta
Abstrak: Sebaran Echinoidea terbesar terdapat di perairan Indo-Malaya. Echinoidea dapat ditemui dari daerah intertidal sampai ke kedalaman 10 meter, dan lamun merupakan salah satu habitat Echinoidea. Echinoidea berperan sebagai konsumen pertama dan sebagai detrivor melalui aktivitas grazing. Grazing merupakan aktivitas yang penting di padang lamun, karena dalam prosesnya Echinoidea membantu penyebaran ruang untuk lamun tumbuh dan menempelnya larva karang. Penelitian ini bertujuan untuk mengetahui struktur dan sebaran komunitas Echinoidea di padang lamun perairan Kelurahan Pulau Panggang, Kepulauan Seribu. Survei lapang dilakukan pada bulan Oktober 2011 yang bertempat di selatan Perairan Karang Congkak (Stasiun 1), selatan Pulau Panggang (Stasiun 2) dan barat Pulau Pramuka (Stasiun 3). Metode penelitian menggunakan transek kuadrat yang diletakkan secara acak berdasarkan keberadaan Echinoidea, untuk mengukur kepadatan Echinoidea, kerapatan dan penutupan spesies lamun, serta mengukur beberapa parameter kualitas air. Pola sebaran Echinoidea dihitung berdasarkan Indeks Sebaran Morisita (Id), sedangkan keterkaitan antara Echinoidea dengan lamun digunakan analisis koresponden. Hasil penelitian menunjukkan bahwa karakteristik habitat lamun dan Echinoidea di lokasi penelitian dicirikan oleh tipe substrat pasir. Spesies lamun yang ditemukan adalah Thalassia hemprichii (Th), Cymodocea serrulata (Cs), Syringodium isoetifolium (Si) dan Enhalus acoroides (Ea). Kerapatan lamun di selatan Perairan Karang Congkak (Stasiun 1) lebih rendah daripada di selatan Pulau Panggang (Stasiun 2). Di lokasi sekitar keberadaan Echinoidea, kerapatan rata-rata lamun yang tertinggi di selatan Perairan Karang Congkak (Stasiun 1) adalah spesies Thalassia hemprichii (Th). Di selatan Pulau Panggang (Stasiun 2) kerapatan rata-rata tertinggi terdapat pada spesies Cymodocea serrulata (Cs). Di barat Pulau Pramuka (Stasiun 3) keberadaan Echinoidea tidak ditemukan di sekitar lamun.

Abstrak: Face recognition is one of the biometric methods which is frequently used. One of the approach in face recognition is view based (photometric) approach which represents the information of the image pixels. In this research, information from the image pixels represented using the image histogram. According to Gonzales (2002), histogram are the basis for numerous spatial domain processing techniques. Histogram is used as input to Voting Feature Intervals 5 (VFI5) algorithm. Range of image histogram is 0-255 divided into several intervals. Afterwards, on training stage will be determined the vote value from single training image per person that will be used in the classification stage. The recognition rate is reached 96.3%.
