Abstract

Budidaya tambak merupakan andalan perikanan di Kabupaten Sidoarjo Provinsi Jawa Timur, namun terdapat berbagai kegiatan yang berpotensi menghasilkan bahan pencemar berupa logam berat di kawasan pesisir yang menjadi sumber air bagi budidaya tambak. Penelitian ini bertujuan untuk menentukan konsentrasi dan status mutu logam berat dalam air sehubungan dengan potensi pencemaran dalam air yang mungkin terjadi dalam kaitannya dengan pemanfaatan untuk budidaya tambak. Penelitian dilaksanakan di kawasan pesisir Kecamatan Jabon Kabupaten Sidoarjo dengan mengambil contoh air pada 12 stasiun pengambilan contoh dan selanjutnya dianalisis di laboratorium untuk logam berat As, Cd, Co, Cr, Cu, Hg, Mn, Mo, Pb, dan Zn. Data dari hasil analisis logam berat dianalisis secara deskriptif dan selanjutnya dengan metode Storage and Retrieval (Storet) digunakan untuk menentukan status mutu air dari logam berat untuk biota laut. Hasil penelitian yang dilakukan pada tahun 2015 ini menunjukkan bahwa kisaran konsentrasi Co, Hg, Mn, Mo, Pb, dan Zn berturut-turut < 0,001-0,072; < 0,001-0,045; 0,02-0,18; < 0,001-0,011; 0,309-0,835; dan 0,01-0,04 mg/L. Hasil penentuan status mutu air menunjukkan bahwa air di kawasan pesisir Kecamatan Jabon tergolong tercemar berat dari logam berat Hg dan Pb untuk biota laut. Disarankan agar kegiatan yang dapat menjadi sumber pencemar logam berat terutama Hg dan Pb di kawasan pesisir Kecamatan Jabon agar dikurangi dan atau mengaplikasikan Instalasi Pengolahan Air Limbah dan merehabilitasi hutan mangrove untuk menjadi bioakumulator logam berat, serta melakukan pengelolaan berkelanjutan yang meliputi pemantauan, pembinaan, dan penegakan hukum sehingga dapat menjadi sumber air untuk budidaya tambak yang produktif dan berkelanjutan.Brackishwater aquaculture is one of the major aquaculture activities in Sidoarjo District, East Java Province. Unfortunately, its sustainability is currently threatened by the increased level of heavy metal pollutants in the coastal waters used as the major water source for the fish farming activity. The objective of this study was to determine the concentrations and distribution of heavy metal elements in the coastal water and devised potential mitigation plans in relation to the sustainability of existing brackishwater in the area. Water samples were collected from 12 sampling stations on the coastal waters of Jabon Subdistrict, Sidoarjo District. Laboratory analyses were performed to identify and measure the level of the heavy metal elements including As, Cd, Co, Cr, Cu, Hg, Mn, Mo, Pb, and Zn. The results of the analysis were descriptively discussed. The Storage and Retrieval (Storet) method was used to determine the quality status of the coastal water based on heavy metals standard limits for marine biota. The results of this 2015 research showed that the concentrations of Co, Hg, Mn, Mo, Pb, and Zn were < 0.001-0.072; < 0.001-0.045; 0.02-0.18; < 0.001-0.011; 0.309-0.835; and 0.01-0.04mg/L, respectively. These heavy metal levels showed that water quality in the coastal area of Jabon Subdistrict was heavily polluted, particularly by Hg and Pb for marine biota. This research recommended that activities in the coastal area suspected to be the sources of heavy metals contaminants, especially Hg and Pb, have to be controlled or reduced. The application of wastewater treatment plants, rehabilitating mangrove forests as heavy metal bio accumulators as well as the implementation of sustainable water management procedures through monitoring, guidance, and law enforcement are highly recommended to ensure the long term sustainability of brackishwater aquaculture activities in the study area.

Abstract

Sebagai salah satu sentra produksi udang di Kecamatan Suppa Kabupaten Pinrang memiliki enam unit panti benih skala kecil (PBSK) dan tiga unit panti benih skala besar (PBSB) sebagai penyuplai benur untuk budidaya di tambak. Penelitian ini bertujuan untuk mengetahui performa pengelolaan pembenihan PBSK dan PBSB di Kecamatan Suppa sebagai pijakan untuk meningkatkan kuantitas, kualitas, dan kontinuitas benur yang dihasilkan. Penelitian dilakukan dengan cara wawancara menggunakan kuesioner untuk mendapatkan informasi pengelolaan panti benih yang dilakukan dan sarana panti benih yang ada pada empat unit PBSK dan dua unit PBSB. Pengukuran dan pengambilan contoh air sumber dilakukan di perairan Suppa di Selat Makassar. Kualitas air sumber dapat mendukung kegiatan produksi benur di panti benih pada musim kemarau, tetapi kualitas air menurun pada musim hujan berupa penurunan suhu dan salinitas air, dan peningkatan kandungan amonia nitrogen total dan nitrat. Bak-bak pemeliharaan larva/pascalarva yang digunakan panti benih di Kecamatan Suppa berbentuk empat persegi panjang dengan dasar bak yang hampir datar dan memiliki volume bervariasi dari 4 sampai dengan 21 m3. Setiap siklus produksi dapat diproduksi benur 1.600.000 sampai 2.250.000 ekor dengan 5-12 siklus/tahun pada PBSK dan 9.500.000 sampai 17.500.000 ekor dengan 5 siklus/tahun pada PBSB. Kunci keberhasilan produksi benur adalah pengelolaan kulitas air tertutama menjaga salinitas, suhu, dan oksigen terlarut sesuai kebutuhan benur. Produksi total benur PBSK dan PBSB di Kabupaten Suppa adalah 209.500.000 ekor/tahun. Pengelolaan kualitas air panti benih di musim hujan di Kecamatan Suppa dapat dilakukan dengan menerapkan Cara Pembenihan Ikan yang Baik dan memodifikasi sarana atau penggunaan sarana tambahan. Suppa Subdistrict is one of the shrimp production centers in Pinrang District. Currently, there are six units of small-scale shrimp hatchery and three units of large-scale shrimp hatchery operated in the subdistrict that supply shrimp fries to local shrimp grow-out brackishwater ponds. This study was conducted to determine the performance of the small and large-scale hatcheries in Suppa Subdistrict in relation to hatchery’s management. The overarching objective of this study was to devise an improved hatchery management to increase the quantity, quality, and production continuity of shrimp fries from the hatcheries. An interview was conducted using a structured questionnaire to elaborate the existing hatchery management practices and facilities of four units of small-scale and two units of large-scale hatcheries. The measurement and sampling of water quality parameters were carried out in Suppa coastal waters of Makassar Strait, where most of the hatcheries sourced their seawater supply. Water quality during the dry season was sufficient to support the hatchery’s activities. However, water quality during the rainy season decreased in terms of reduced water temperature and salinity, and increased total ammonia nitrogen and nitrate contents. The rearing tanks were of rectangle shape with nearly flat bottom and volume varied from 4 to 21 m3. The small-scale hatcheries produced between 1,600,000 and 2.250,000 of shrimp fries per cycle with a total of 5-12 production cycles/year. The large-scale hatcheries produced 9,500,000 up to 17,500,000 of shrimp fries per cycle with at least five production cycles/year. The total production of shrimp fries from the existing hatcheries in Suppa Subdistrict reached up to 209,500,000 shrimp fries per year. During rainly season, the water quality management of the existing hatcheries in Suppa Subdistrict could be improved by strictly implementing best hatchery management practices and through modification of hatchery’s facilities or setting up additional water quality monitoring instruments.
