Abstract

Anchovy Pekto is one of fish commodity that has high economic value in Medan, especially in Belawan. This type of fish is also in demand in the local market. So as fisherman of anchovies put Anchovy Pekto as a main target catch for their fishing. But, this activity has a negative impact to Anchovy Pekto population. This research was conducted in Belawan in June to August 2015, which aims to examine growth pattern, growth parameters, condition factor, and the rate of exploitation in order to provide appropriate management model for the fish resources. Primary data is total length and wet weight of 1137 samples of Anchovy pekto, whereas secondary data is the sea surface temperature data. The cohort length of fish is separated by Bhattacarya method in FISAT II software. Based on the estimation growth parameters by Von Bertalanffyin which the asymptotic length (L∞) = 7,04 cm, the growth coefficient (K) = 1,50 per year and the age at zero length (to) = -0,15 from the empiricalPauly’s method. Then the growth equation of Anchovy Pekto is Lt = 7,04 (1-e[-150(t+0,15]). The value of b obtained from the relations of weight- length Anchovy Pekto 2,975. Anchovy Pekto growth pattern is negative allometric with an equation growth W=0,007L2,975. the highest and the lowest valueof factor conditionare 0,53 and 1,86. the rate of total mortality (Z) Anchovy Pekto is 4,42 per year with natural mortality rate (M) 2,87 per year, and fishing mortality rate 1,54 per year so that the rate of exploitation is obtained with the amount 0,34 and the value of the exploitation rate does not exceed the optimum exploitation which is 0,5.Keywords: Anchovy Pekto, Long-weight, Pattern Of Growth, Factor Condition, Mortality.

Abstract

Pesisir Timur Pulau Weh (PTPW) is a water natural reserve conservation area located in the eastern part of Weh Island. The condition of coral substrates in PTPW has suffered a lot of damage based on bleaching cases that have hit Sabang waters in 2016. Coral conditions can be measured by looking at the abundance of fish indicators of the Chaetodontidae group. Therefore, this study aimed to measure coral conditions and the abundance of Chaetodontidae coral fish, as well as analyze the relationship between the percentage of coral cover and the abundance of Chaetodontidae coral fish. Data of coral were collected using the Point Intercept Transect method with a length of 50 meters, while the abundance of fish used the Underwater Visual Census technique and the Belt Transect method with a length of 50 meters and a total belt width of 5 meters. The results showed that the coral conditions in PTPW were in poor to fair condition with the highest cover at The Sumur Tiga site (36.83%) and the lowest at The Ujung Kareung site (11.5%). The highest abundance of Chaetodontidae fish was found at Ujung Seuke site (1253.3 ind/ha) and the lowest was found at Anoi Itam site (186.7 ind/ha). The results of the correlation analysis between the percentage of coral cover and the abundance of Chaetodontidae coral fish showed a positive relationship (r = 0.482), but it was not significant (p>0.05), and the regression equation obtained Y = 17.16x + 166.52 with a determination coefficient of 18.3%, which indicated that the correlation between the two variables was very weak.

Abstract

The Belawan watershed is located at  Deli Serdang Regency and Medan City, with mountainous terrain (70.58%), hills (35.15%), and slopes (20.28%). This study aims to identify  the risk of erosion of cropland, especially coffee, corn, and chocolate,  to identify  more appropriate erosion control measures to achieve regional protection objectives . The research was conducted in the upstream Belawan watershed in the Sibolangit, Bandar Baru, and Kutalimbaru regions  from September 2020 to December 2020. The magnitude of the erosion  hazard value  is analysed using the USLE approach . The USLE method on the amount of erosion is determined by 5 (five) factors, these factors are the rainfall erosion  factor (R); soil erodibility factor (K); vegetation factor (C); conservation factor (P) and topography factor (LS). The erosion rate valuefor land use types  varies from 95.27 tons/Ha.yr to 232.43 tons/Ha.yr. The amount of erosion that can be tolerated in land use  for coffee, corn, and cacao  ranges from 19.94 tons/Ha.yr to 39.79 tons/Ha.yr. The risk level  for erosion  in coffee areas 4.83 and 10.86 with high criteria and very high criteria; in areas  of corn  event 6.29 and 8.38 with high criteria and in brown areas  5.24 and 3.88 with high criteria and medium criteria.

Abstract

Penelitian tentang Hubungan Sistem Usaha Tambak dan Jenis Teknologi yang Digunakan Terhadap Produksi Tambak di Desa Tanjung Rejo Kecamatan Percut Sei Tuan telah dilaksanakan. Penelitian ini bertujuan mengukur dan menguraikan pengaruh sistem usaha tambak dan jenis teknologi yang digunakan terhadap produksi usaha tambak. Penelitian ini menggunakan metode survey, observasi lapangan dan pendalaman wawancara dengan menampilkan data primer dan sekunder. Variabel yang digunakan adalah sistem usaha tambak, teknologi yang digunakan dan hasil produksi. Hasil penelitian menunjukkan bahwa hasil produksi yang menggunakan sistem usaha tambak secara monokultur lebih sedikit (rendah) dibanding petani tambak (responden) yang menggunakan sistem usaha secara polikultur, dikarenakan petani tambak yang memilih pembudidayaan secara monokultur hanya mengandalkan satu komoditas saja sehingga jika komoditas tersebut di pasca panen ternyata gagal maka petani tersebut sama sekali tidak mendapatkan keuntungan yang besar dibanding petani tambak yang memilih pembudidayaan secara polikultur. Responden yang memilih jenis teknologi secara ekstensif (tradisional) rata-rata hasil produksinya rendah dibandingkan dengan responden yang memilih semi intensif dalam teknologi yang digunakan. Hal ini dikarenakan sistem ekstensif (tradisional) hanya bermodalkan penggunaan pakan yang alami di kolam atau hanya memanfaatkan dari alam dengan tidak menambahkan pakan buatan.
