"ABSTRAKTelah dilakukan penelitian lamun dan perifiton di wilayah perairan Teluk Lampung yaitu Hurun, Lahu, dan Ringgung untuk kondisi dan perubahan struktur komunitas padang lamun dan perifiton. Metode yang digunakan adalah transect menggunakan kuadrat berukuran 50x50cm. Data hasil pengamatan dianalisis indeks keanekaragaman, kemerataan dan dominasi serta keterkaitan antara padang lamun, perifiton dan beberapa parameter lain menggunakan uji Spearman. Ditemukan 4 jenis dari 2 famili yaitu Hydrocharitaceae (Enhalus acoroides, Thalassia hemprichii, dan Halophila minor) dan Famili Potamagetonaceae (Halodule uninervis). Berdasarkan pengamatan ditemukan sebanyak 22 jenis perifiton baik alga epifit maupun meiofauna epifit. Perifiton dibagi dalam 10 kelompok yaitu Diatomae, Dinoflagellata, Copepoda, Medusae, Amphipoda, Isopoda, Cypris, Polychaeta, Bivalvia, dan Gastropoda. Dalam kurun waktu 10 tahun, terjadi penurunan indeks keanekaragaman, baik pada lamun maupun perifiton, yang menunjukkan penurunan stabilitas ekosistem padang lamun. Berdasarkan hasil uji Spearman, diketahui bahwa terdapat korelasi positif antara tingkat kerapatan setiap jenis lamun dengan tingkat kepadatan perifitonnya, kerapatan lamun dengan kandungan organik substrat, serta biomassa di bawah substrat dengan kandungan organik substrat.

ABSTRACTThe research of seagrass and periphyton in Lampung bay territorial has been done in Hurun, Lahu, and Ringgung, to know the conditions and changes of community structure of seagrass beds dan periphyton. Transect method using a square 50x50cm. Data observations were analyzed the diversity, evenness and dominance index. Linkages between seagrass, periphyton and some other parameters analyzed using the Spearman test. There 4 specieces from 2 families of seagrass found in Hurun, Lahu and Ringgung, that are Hydrocharitaceae (Enhalus acoroides,Halophila minor, and Thalassia hemprichii) and Potamagetonaceae (Halodule uninervis). Based on the observations found 22 species of algae either epiphytic periphyton and epiphytic meiofauna. Periphyton were divided into 10 groups Diatomae, Dinoflagellates, Copepods, Medusae, Amphipods, Isopods, Cypris, Polychaeta, Bivalves, and Gastropods. In the past 10 years, decline on diversity index and dominance index increased, both in seagrass and periphyton, which showed a decrease in the stability of seagrass ecosystems. Based on the Spearman test, there is a positive correlation between the density of periphyton and seagrass (spesific on type), the density of seagrass and substrate organic content, also biomass below substrate and substrate organic content."

"While everyone can consider themselves as a fan, but not many fans has the effort to be a part of a fandom in which the franchise that already ended. Indo Harry Potter is a community based in Jakarta in which the member still actively participate and engage despite the fact that the Harry Potter franchise has been ended for nine years. This paper will attempt to understand the Indo Harry Potter community through the lens of participatory cultural. Through secondary research using data from research conducted by Ramayudanto, Soetomo, and Yudhistira in 2019, the research found Indo Harry Potter can be qualified as an example of participatory culture.

Meskipun setiap orang dapat menganggap diri mereka sebagai penggemar, tetapi tidak banyak penggemar yang berusaha untuk menjadi bagian dari fandom di mana waralaba tersebut telah berakhir. Indo Harry Potter adalah komunitas yang berbasis di Jakarta di mana anggotanya masih aktif berpartisipasi dan terlibat meskipun waralaba Harry Potter telah berakhir selama sembilan tahun. Tulisan ini akan mencoba untuk memahami komunitas Indo Harry Potter melalui lensa budaya partisipatif. Melalui penelitian sekunder menggunakan data dari riset yang sudah dilakukan oleh Ramayudanto, Soetomo, dan Yudhistira pada tahun 2019, penelitian ini menemukan bahwa budaya partisipatif dapat ditemukan pada komunitas di Indo Harry Potter."
