Abstract

Masyarakat yang tinggal di kawasan Pelabuhan Perikanan Pantai Carocok Tarusan mengolah ikan teri menjadi teri asin yang disebut ikan bada cuci. Ikan bada cuci yang dijual di Padang, Bukittinggi, dan Pekanbaru saat ini harganya kalah bersaing dengan produk serupa dari daerah lain. Apabila hal ini berlanjut maka masyarakat akan menderita kerugian dan bahkan kehilangan mata pencaharian. Penelitian ini bertujuan: 1) mengidentifikasi akar penyebab permasalahan harga ikan bada cuci dari Pelabuhan Perikanan Pantai Carocok Tarusan kalah bersaing dengan produk serupa dari daerah lain, 2) memberikan rekomendasi agar harga ikan bada cuci dari Pelabuhan Perikanan Pantai Carocok Tarusan dapat lebih bersaing. Metode penelitian menggunakan metode survei dan teknik pengumpulan data berupa sensus. Tujuan pertama penelitian dicapai dengan menggunakan Diagram Ishikawa. Adapun tujuan kedua dicapai dengan mengidentifikasi proses produksi ikan bada cuci dan peluang penurunan biaya produksinya secara deskriptif. Hasil penelitian menunjukkan bahwa akar penyebab permasalahan harga ikan bada cuci dari Pelabuhan Perikanan Pantai Carocok Tarusan kalah bersaing dengan produk serupa dari daerah lain adalah kurangnya pengetahuan manajemen usaha dan modal usaha dari pengolah. Rekomendasi yang dapat diberikan agar harga ikan bada cuci dari Pelabuhan Perikanan Pantai Carocok Tarusan dapat bersaing antara lain adalah: 1) dari segi biaya produksi, terdapat biaya yang berpeluang untuk dikurangi yaitu harga bahan baku dan harga bahan bantu pengolahan, 2) dari segi teknis, diperlukan modernisasi peralatan pengolah dan pengering, serta 3) dari segi manajemen, diperlukan pelatihan manajemen usaha dan pengembangan pemasaran untuk pengolah. Kata kunci: Carocok Tarusan, ikan bada cuci, ikan teri, persaingan harga, proses produksi

Abstract

Enhalus acoroides is the largest population of seagrasses in Indonesia. However, growth rate and productivity analyses of Enhalus acoroides and the use of satellite data to estimate its the productivity are still rare. The goal of the research was to analyze the growth rate, productivity rate,seasonal productivity of Enhalus acoroides in Pari island and its surroundings. The study was divided into two phases i.e., in situ measurments and satellite image processing. The field study was conducted to obtain the coverage percentage, density, growth rate, and productivity rate, while the satellite image processing was used to estimate the extent of seagrass. The study was conducted in August 2011 toJuly 2012 to accommodate all four seasons. Results showed that the highest growth rate andproductivity occurred during the transitional season from west Monsoon to the east Monsoon of 5.6cm/day and 15.75 mgC/day, respectively. While, the lowest growth rate and productivity occurred during the transition from east Monsoon to the west Monsoon of 3.93 cm/day and 11.4 mgC/day, respectively. Enhalus acoroides productivity reached its maximum during the west Monsoon at 1081.71 mgC/day/m2 and minimum during east Monsoon with 774.85 mgC/day/m2 . Based on ALOS data in 2008 and 2009, total production of Enhalus acoroides in the proximity of Pari islands reached its maximum occur during the west Monsoon (48.73 – 49.59 Ton C) and minimum during transitional season (16.4-16.69 Ton C). Potential atmospheric CO2 absorption by Enhalus acoroides in Pari island was estimated at the number 60.14 – 181.82 Ton C.

Abstract

Process of light reduction or loss (attenuation) by scattering and absorption is affected by solar zenith, time, depth, and seawater constituents. Downwelling diffuse attenuation coefficient (Kd) is important to understand for light penetration and biological processes in ocean ecosystem. It is, therefore, important to know the Kd value and its variability in ocean ecosystem. The objective of this study was to determine downwelling diffuse attenuation coefficients and its variability form in situ measurements of different water types. In situ downwelling irradiances (Ed) were measured using a submersible marine environmental radiometer instrument (MER) during a clear sky, calm water condition, and at the time range of 10:30 a.m. up to 14:00 p.m. local time in the northeastern Gulf of Mexico in April 2000. In general, Ed values decreases exponentially with depth. Ed at 380 nm exhibited the lowest attenuation (the most penetrative light), while Ed at 683 nm exhibited the highest attenuation (the most light loss at the top of water column). Overall, the Kd patterns tended to decrease from 380 nm to 490 nm (blue-green wavelength), and increase from 490 nm to 683 nm (green-red wavelength). Kd values in offshore region were relatively lower than in coastal region. Kd can be used to determine the depth of euphotic zone in offshore or teh case-1 water type and the depth of one optical depth (the water column depth where the ocean color satellite can possibly sense).
