Abstract: This study aims to analyze the relation of marine debris to gastropods in the mangrove ecosystem. This research was conducted from October to December 2019 in the Tongkaina mangrove forest. The method used in this research is the line transects method with 2 different stations. Then do the data analysis of waste density, gastropod abundance index, frequency, ersity index, uniformity, and dominance. Then, analyzing a simple linear regression and correlation is performed to see the relationship between marine debris and gastropod abundance in a mangrove ecosystem. The results showed that the highest inorganic marine debris in the Tongkeina mangrove ecosystem is plastic and followed by cloth, wood, metal and the least was glass. The species of Gastropods found in the mangrove ecosystem are Littoraria scabra, Nerita undulata and Terebralia sulcata. The highest abundance of gastropod species was found at station 2 in transects 1 by Littoraria scraba. The results of the linear regression analysis show that there is a relationship between waste and abundance of gastropods. The increasing amount of waste, lower the abundance of gastropods. Where the correlation value is -0.20506.Keywords: Correlation Marine debris Gastropods Mangrove Ecosystem. ABSTRAKPenelitian ini bertujuan untuk menganalisis hubungan s ah laut terhadap gastropoda di ekosistem mangrove. Penelitian ini dilakukan pada bulan Oktober s ai Desember 2019 di hutan mangrove Tongkaina. Metode yang digunakan adalah metode line transek dengan 2 stasiun berbeda. Kemudian dilakukan analisa data kepadatan s ah, indeks kelimpaha gastropoda, frekuensi, indeks keanekaragaman, keseragaman dan dominasi. Selanjutnya dilakukan analisa regresi lineier sederhana serta korelasi untuk melihat hubungan yang terjadi antara s ah dan kelimpahan gastrooda. Hasil penelitian menunjukkan bahwa s ah anorganik jenis plasik yang tertinggi di ekosistem mangrove pantai Tongkaina diikuti s ah jenis Kain, Kayu, Logam dan yang paling sedikit adalah s ah jenis kaca. Jenis gastropoda yang ditemukan di ekosistem mangrove yaitu Littoraria scabra, Nerita undulata dan Terebralia sulcata. Nilai kelimpahan jenis gastropoda tertinggi terdapat di stasiun 2 di transek 1 oleh Littoraria scraba. Hasil analisa regresi linier menunjukan bahawa ada hubungan yang terjadi antara s ah dan kelimpahan gastropoda yang dilihat dari anlisis regresi linier sederhana. Semakin meningkatnya jumlah s ah maka semakin rendah kelimpahan gastropoda. Dimana nilai korelasinya sebesar -0.20506.Kata Kunci : Korelasi S ah Laut Gastropoda Ekosistem Mangrove.

Abstract: The focus of this article is a crisis of reproduction that beset the contemporary popular music industry from the late 1990s onwards. In the early 21st century the music industry began to suffer from declining sales, negative growth and financial losses. Explanations internal to the music industry identified the cause of the crisis as the rise of Internet piracy, although the emergence of software formats, such as MP3, and Internet distribution systems is more accurately described as a ‘tipping point’ that brought into focus a set of deeper structural problems for the industry related to changing forms of popular music consumption. Drawing on research undertaken by the authors within US music companies, the article examines responses to the crisis in the form of three distinctive business models that represent different strategies in the face of the contemporary crisis of the musical economy, an arena within which a range of experiments are being undertaken in an effort to develop new ways of generating income. Nevertheless, there is reluctance within the industry to embrace the more radical organizational changes that might allow it to fully accommodate the impact of software formats and Internet distribution systems. A key reason for this, we argue, is the stakes that the leaders of the major record companies have in the preservation of the current social order of the musical economy.
