Lobster resources are one of renewable resources but if catches are increasing without any control will cause a depleted resource. Catching lobsters is not only in the adult phase but all phases are captured. The purpose of this study to determine the composition of lobster seeds between depths that have a high value of lobster seeds collection so that it can be used as a reference for lobster protection in nature. This research was conducted in January – February 2019, located in Pacitan district with the operational area in Wawaran beach waters. The statistical method used in this research was Chi-Square analysis and Kruskall-Wallis. Based on the results of the operation atracror puerulus lobster in two different depths (14 and 20 meters) in Wawaran beach waters found that there are four species puerulus, i.e., Panulirus homarus, Panulirus penicillatus, Panulirus ornatus and Panulirus versicolor. Its found that different depths did not affect the composition of the collected puerulus species. Then the Kruskal-Wallis test at 14 meters and 20 meters depth found a significant difference in the value of each type of lobster. The type of puerulus from Panulirus homarus has the dominant results compared than the other three species.
Abstrak -Citra ikan tuna harus dilakukan proses segmentasi yang baik sebelum masuk ke tahapan klasifikasi. Hasil segmentasi yang baik adalah objek dan background terpisah dengan jelas. Citra ikan tuna yang memiliki sebaran cahaya tidak merata dan memiliki tekstur yang komplek akan menghasilkan kesalahan segmentasi. Salah satu metode segmentasi pada citra adalah seeded region growing dan parameter yang digunakan hanya dua yaitu seed dan threshold. Penelitian ini mengusulkan metode seeded region growing pada ruang warna HSI untuk segmentasi citra ikan tuna. Ruang warna RGB (red green blue) pada citra ikan tuna ditransformasikan ke dalam ruang warna HSI (hue saturasi intesitas) yang kemudian hanya ruang hue untuk dijadikan segmentasi dengan menggunakan seeded region growing. Penentuan parameter seed dan threshold dilakukan secara manual dan hasil dari segmentasi tersebut dilakukan refinement dengan morfologi matematika. Pengujian dilakukan sebanyak 30 citra dan metode evaluasi hasil segmentasi menggunakan RAE (relative foreground area error), MAE (missclassification error) dan MHD (modified Hausdroff distance). Citra ikan tuna berhasil dilakukan segmentasi dengan dibuktikan nilai RAE, ME dan MHD secara berturut adalah 5,40%, 1,53% dan 0,41%.Kata kunci -HSI, citra ikan tuna, morfologi matematika, seeded region growing Abstract -The image of the tuna must have a good segmentation results before entering process classification. The result of good segmentation is object and background separate clearly. The image of tuna which has a distribution of light that is uneven and has a complex texture will produce an error segmentation. One method of image segmentation was seeded region growing and parameters that used only two, namely seed and threshold. This research proposed method seeded region growing in the HSI color space for image segmentation of tuna. The Color space of RGB (red green blue) on image of tuna transformed into a color space HSI (hue saturation intensity) then only the hue color space used as segmentation by using seeded region growing. Determination of seed and threshold parameters can do manually and the result of the segmentation do refinement with mathematical morphology. The experiment using 30 image of tuna to segmentation and evaluation methods using RAE (relative foreground area error), MAE (missclassification error) and the MHD (modified Hausdroff distance). The image of the tuna successfully performed segmentation evidenced by a value RAE, ME and MHD respectively are 5,40%, 1,53% dan 0,41%.
There are about six species of tropical spiny lobsters within a group of Panulirus inhabit Indonesia archipelagic waters. A lobster fishery is among relevant national fisheries products. Their social, economic, and ecological contributions to the country are significant. Hence, the lobster’s resource sustainable use always becomes a challenge for the management authority. Life phase distribution of marine organisms in space and time is critical information for management. The equivalent study can be phrased for the lobster population in the South Sea of Java Island of Eastern Indian Ocean. The purpose of this study was to develop formulations to protect ecosystems and conserve lobster resources. Distribution of pueruli larvae of spiny lobster of Panulirus species was surveyed in the South Sea of Pacitan, East Java from January to February 2019. The number of pueruli larvae caught were counted and compared among the species. An ANOVA test was performed for data analysis. There were four species of lobster found. The dominant species was Panulirus homarus (Scalloped spiny lobster). It was followed by P. versicolor (Painted spiny lobster), and P. ornatus (Ornate spiny lobster). The least dominant was P. pennicillatus (Pronghorn spiny lobster). Comparative study on life stage distribution concerning to larval dispersal may support the connectivity hypotheses of the lobster population in the region.

Most of the document summary are arranged extractive by taking important sentences from the document. Extractive based summarization often not consider the connection sentence. A good sentence ordering should aware about rhetorical relations such as cause-effect relation, topical relevancy and chronological sequence which exist between the sentences. Based on this problem, we propose a new method for sentence ordering in multi document summarization using cluster correlation and probability for English documents. Sentences of multi-documents are grouped based on similarity into clusters. Sentence extracted from each cluster to be a summary that will be listed based on cluster correlation and probability. User evaluation showed that the summary result of proposed method easier to understanding than the previous method. The result of ROUGE method also shows increase on sentence arrangement compared to previous method. Keywords: Document Summarization, Cluster Ordering, Cluster Correlation, Probability AbstrakSebagian besar ringkasan dokumen dihasilkan dari metode extractive, yaitu mengambil kalimat-kalimat penting dari dokumen. Ringkasan dengan metode extractive sering tidak mempertimbangkan hubungan antar kalimat. Pengurutan kalimat yang bagus menunjukkan hubungan rhetorical, seperti hubungan sebab akibat, topic yang relevan, dan urutan yang kronologis diantara kalimat. Berdasarkan permasalahan ini, diusulkan sebuah metode baru untuk pengurutan kalimat pada peringkasan dari beberapa documen menggunakan cluster correlation dan probabilityuntuk dokumen berbahasa inggris. Kalimat dari beberapa dokumen dikelompokkan berdasarkan kemiripannya ke dalam cluster-cluster. Kalimat diekstrak dari setiap cluster untuk menjadi ringkasan, ringkasan akan diurutkan berdasarkan cluster correlation dan probability. Hasil evaluasi pengguna menunjukkan hasil ringkasan dari metode usulan lebih mudah dipahami dari pada metode sebelumnya. Hasil ROUGE juga menunjukkan peningkatan susunan kalimat dari metode sebelumnya.Kata Kunci: Peringkasan Dokumen, Pengurutan Cluster, Cluster Correlation, Probability
Menurut undang-undang nomor 43 tahun 2007 tentang perpustakaan, Perpustakaan adalah institusi pengelola koleksi karya tulis, karya cetak, dan karya rekam secara profesional dengan sistem yang baku guna memenuhi kebutuhan pendidikan, penelitian, pelestarian, informasi, dan rekreasi para pemustaka. Seiring perkembangan teknologi yang saat ini sangat berkembang dengan cepat kini ada sistem yang dapat mempermudah untuk mengelola perpustakaan. Namun, perpustakaan di SMKN 2 Banjarmasin pengelolaannya masih menggunakan cara manual, kurang baik, dan tidak terkontrol. Berdasarkan hal tersebut, maka diperlukanlah pembangunan dan perancangan sistem informasi perpustakaan di SMKN 2 Banjarmasin, agar pegawai di perpustakaan tersebut lebih mudah dalam mengelola pendataan buku, anggota, peminjaman buku, pengembalian buku, dan denda di perpustakaan SMKN 2 Banjarmasin. Dalam perancangan menggunakan metode SDLC (System Development Life Cycle) atau dalam bahasa indonesia disebut dengan siklus hidup pengembangan sistem. Adapun untuk tahap-tahap dari metode SDLC yaitu tahap perencanaan, analisis, perancangan, implementasi, testing dan integrasi, pemeliharaan atau perawatan. Sistem Informasi Perpustakaan SMKN 2 Banjarmasin ini telah berhasil dirancang dan dibangun dengan baik untuk mempermudah pihak sekolah dalam melakukan pengelolaan pendataan buku, peminjaman buku, pengembalian buku serta denda di perpustakaan SMKN 2 Banjarmasin.
