Abstract

ABSTRAK : Di dunia ada 7 jenis penyu dan 6 diantaranya terdapat di Indonesia. Penyu telah mengalami penurunan yang drastis jumlah populasinya dalam jangka waktu terakhir ini. Berkurangnya populasi penyu itu antara lain dipengaruhi oleh beberapa faktor dan salah satunya adalah penyu yang tertangkap secara bycatch oleh jaring nelayan. Penelitian ini bertujuan untuk mengetahui lokasi dan morfometri penyu yang tertangkap secara bycatch di perairan Sambas. Penelitian ini dilakukan pada tanggal 10 Maret - 31 Mei 2016 di Perairan Sambas, Kalimantan Barat. Metode yang digunakan dalam penelitian ini adalah metode deskriptif. Data yang dikumpulkan yaitu lokasi, jumlah dan morfometri yang meliputi panjang karapas dan lebar karapas penyu yang tertangkap secara bycatch serta pengambilan data parameter perairan yaitu suhu, pH, salinitas, kecerahan, dan kedalaman. Data yang telah didapat dianalisis menggunakan grafik dan analisis regresi korelasi. Hasil penelitian menunjukkan bahwa daerah laut Selimpai merupakan lokasi tertangkapnya penyu secara bycatch paling banyak dengan jumlah 4 ekor Penyu hijau dan 3 ekor Penyu Lekang tertangkap secara bycatch diberbagai lokasi di perairan Sambas. Morfometri penyu yang tertangkap secara bycatchmemiliki ukuran panjang karapas berkisar 38 - 68 cm dan lebar karapas berkisar 35 - 65 cm. Penambahan ukuran panjang karapas diikuti dengan penambahan ukuran lebar karapas yang dibuktikan dengan nilai determinasi (R²) sebesar 0,991 atau 99,1 %. Parameter lingkungan memiliki nilai suhu rata - rata adalah 28,95°C, nilai pH adalah 7, nilai salinitas rata - rata adalah 28,27 ‰, nilai kecerahan rata - rata adalah 2,26 m dan nilai kedalaman rata - rata adalah 12,86 m.ABSTRACT : In the world there are 7 species of sea turtles and 6 of which are found in Indonesia. The sea turtles has undergrone a drastic decline in the number of population in this last periode of time. The decline in the population of sea turtles that, among others, is influence by several factors and one of them was captured bycatch by fishermen nets. This research aims to know the location and morphometrics of sea turtles are caught in bycatch in the waters of Sambas, West Kalimantan. This research wa conducted on 10th march – 31st may 2016 in the waters of Sambas, West Kalimantan. The methods use in this research is descriptive method. The data collected that is the location, number and morphometrics which includes carapace length and carapace width of sea turtles caught in bycatch and data retrieval parameters water is temperature, pH, salinity, brightness and depth. Data obtaines were analyzed using graph and correlation regression analysis. The results showed that in sea Selimpai was the location of the capture of sea turtles in most heavily by the number of 4 green turtles and 3 olive ridley are caught in bycatch has a size of carapace length range in 38 - 68 cm and carapace width range in 35 - 65 cm. The additions of the carapace length size affects the size of the addition of the carapace width as evidence by value determination (R²) of 0,991 atau 99,1 %. Environmental parameters has a value of average temperature is 28,95°C, a value of pH is 7, the value of the average salinity is 28,27 ‰, average brightness value is 2,26 m and an average depth is 12,86 m.

Abstract

The purpose of this study was to identify the role of women in freshwater fish farming households. The research was carried out in Sumbersari Village, Metro Selatan District with consideration as a center for freshwater fisheries in Metro City in November-December 2020. Respondents to the study consisted of 20 freshwater fish farming households which were selected using the simple random sampling method. Data were analyzed using qualitative methods and Harvard methods to see the role of women in gender activity profiles (reproductive, productive and social division of labor), access to resources and benefits and control over resources and benefits based on gender. The role of women in aquatic fish farming households is dominated by reproductive activities (domestik work). Activities whose division of labor is dominated by men include: 1) Productive division of labor, 2) Social division of labor, 3) Access to resources, and 4) Control over resources. Equality in the division of labor based on gender has occurred in access to benefits and control over benefits activities. In general, the division of labor in the air-tawae fish farming household is not equal between men and women. Women dominate in the division of labor in the domestik sector and men dominate in the productive, social, and access to family resources sectors.
