Abstract

The study was aimed at knowing the feasibility of the waters of Dodinga Bay for seaweed; Kappaphycus alvarezii culture development.  The study used a survey method covering aquatic physical, chemical and biological parameters.  Result showed that physical, chemical and biological parameters fulfilled the criteria for the seaweed growth. Based on the suitability of the water used in this study, Dodinga Bay waters was categorized as S-2 class or having median suitability criteria, i.e. the water possessed moderate threshold for seaweed culture or had animal effect on the aquatic environmental quality, and could still be utilized for seaweed culture development under several technical prerequisites. Keywords: Kappaphycus alvarezii, seaweed culture development.   Penelitian ini bertujuan untuk mengetahui kelayakan perairan untuk pengembangan budidaya rumput laut Kappaphycus alvarezii di Pantai Dodinga.  Penelitian ini menggunakan metode survei meliputi parameter fisik, kimia dan biologi perairan.  Hasil penelitian menunjukkan bahwa parameter fisik, kimia dan biologi memenuhi kriteria untuk pertumbuhan rumput laut.  Berdasarkan kesesuaian air yang digunakan dalam penelitian ini, perairan Teluk Dodinga dikategorikan kelas S-2 atau memiliki kriteria kesesuaian median, yaitu perairan yang memiliki batas moderat untuk budidaya rumput laut atau kurang berpengaruh pada kualitas lingkungan air, dan masih bisa dimanfaatkan untuk pengembangan budidaya rumput laut di bawah beberapa prasyarat teknis. Kata kunci: Kappaphycus alvarezii, pengembangan budidaya rumput laut.

Abstract

Rumput laut Kappaphycus alvarezii merupakan komoditas akuakultur yang memiliki nilai ekonomis tinggi. Pengembangan budidaya rumput laut di Maluku Utara saat ini mulai berkembang. Pembudidaya rumput laut yang terdapat di Kabupaten Halmahera Barat, Provinsi Maluku Utara didorong menjadi kampung budidaya rumput laut oleh Kementerian Kelautan dan Perikanan (KKP). Kegiatan ini bertujuan untuk memberikan pelatihan dan pendampingan manajemen budidaya rumput laut sistem teknologi jaring kantong kepada pembudidaya. Kegiatan ini dilakukan mulai bulan September sampai November 2022, bertempat di Desa Tuada, Kabupaten Halmahera Barat, Maluku Utara. Kegiatan ini dimulai dari sosialisi inovasi kemudian dilanjutkan dengan pelatihan secara langsung kepada pembudidaya, mulai dari persiapan hingga pemeliharaan. Secara rinci, kegiatan yang dilakukan meliputi : 1) sosialisasi inovasi; 2) persiapan alat dan bahan; 3) pembuatan jaring kantong; 4) pemasangan tali; 5) penyediaan bibit rumput laut; 6) pemasukan bibit dalam kantong; 7) penempatan di lokasi budididaya dan 8) pemeliharaan. Dengan dilakukannya kegiatan ini, diharapkan pembudidaya memiliki wawasan dan keterampilan untuk meningkatkan produksi rumput laut di Kabupaten Halmahera Barat.

Abstract

Tridacna sp. is one of the protected heritage in Indonesia, because its population has declined dramatically. Tridacna sp. is the largest type of shellfish in water. Like a clam, Tridacna sp. can be used as a bioindicator of the aquatic environment because it can accumulate more heavy metals than other aquatic organisms due to its nature as a filter feeder. This study aims to determine the health condition of Tridacna sp. in the waters of Obi Island with a histopathological analysis approach. The histopathological analysis aims to see the level of tissue damage due to the accumulation of heavy metals. Observation of water quality was also observed in this study. Water quality parameters observed in-situ are temperature, brightness, salinity, pH, and dissolved oxygen. While the water quality parameters observed ex-situ are nitrate, orthophosphate, ammonia, iron (Fe), and nickel (Ni). Observations show that the water temperature is at 27.99 ℃. Water brightness is at 13 m. Salinity is at 32.13 mg / l. The acidity of the waters is 8.64. Ammonia is at 0.4 mg / L. Nitrate is at 0.009 mg / L. Orthopedics are at 0.016 mg / L. Dissolved oxygen waters are at 3.77 mg / L. The iron (Fe) level of water is at 0.6 mg / L. The level of nickel (Ni) waters is at 0.06 mg / L. This study shows the health condition of Tridacna sp. the histological approach shows that the condition of the network has changed. Symptoms of this change indicate the condition of the Tridacna sp. degeneration and cell necrosis. This change is thought to be influenced by heavy metals. Heavy metal content in liquids exceeds the quality standard threshold.Keywords:  Tridacna sp.; Heavy metal; Water quality; histopathological.

Abstract

This study aims to determine the content of nickel (Ni) and iron (Fe) as well as histopathological analysis of marine fish in Obi Island waters as a bioindicator of pollution. Besides, water quality conditions were carried out in-situ and ex-situ observations. The parameters observed were temperature, brightness, salinity, pH, dissolved oxygen, nitrate, orthophosphate, ammonia, iron (Fe), and nickel (Ni). The results showed the temperature range between 26.48 ℃ to 27.99 ℃ below the quality standard or low temperature. The brightness of the relationship between 12 m and 13 m is under quality standards. The salinity range between 31.01 ppt to 32.13 ppt below the quality standard. The pH range is from 8.6 to 8.7 in high or alkaline conditions. Ammonia range between 0.4 mg / L to 0.7 mg / L exceeds the quality standard. The range of nitrate between 0.009 mg / L to 0.012 mg / L exceeds the quality standard. The range of phosphate between 0.016 mg / L to 0.019 mg / L exceeds the quality standard. The DO range between 3.68 mg / L to 3.77 mg / L lower than the quality standard. The metal range of 0.6 mg / L to 0.9 mg / L exceeds the quality standard. The range of Ni metal between 0.06 mg / L to 0.09 mg / L exceeds the quality standard. Histopathological analysis showed that the liver had a hemorrhage, degeneration of blood vessels, vacuolate degeneration, necrosis, or cell death. The muscles experience edema, degeneration of muscle fibers, atrophy of muscle bundles, vacuolar degeneration of muscle Bundles, hemorrhage, infiltration of lymphocytes, and necrosis. The intestine experience infiltration of lymphocytes, melanomacrophages, and necrosis. While P. tayenus fish ovaries showed necrosis structure oocytes. This research can be a reference for warning of heavy metal pollution in Obi Island waters, binding to the nature of heavy metals that can accumulate in fish tissue.Keywords: Water quality; Heavy Metal; Pollution; Histopathological; Obi Island.

Abstract

The potential of aquaculture in North Maluku Province, especially the Obi islands, has not been maximally utilized. One commodity that can be developed is Whiteleg shrimp. This commodity is a major aquaculture commodity with important economic value. Analysis of the suitability of waters for Whiteleg shrimp cultivation is an early stage of activity that greatly determines the success of cultivation. Therefore, this study aims to assess the suitability of waters for the development of Whiteleg shrimp aquaculture on the island of Obi. This study was conducted in the waters of Soligi, Kawasi, Baru, Akegula, Laiwui, Buton, Jikotamo, Sambiki, and Anggai of Obi Island, South Halmahera Regency. Water quality parameters observed were temperature, brightness, depth, current speed, salinity, pH, dissolved oxygen, nitrate, and phosphate. Each parameter was then analyzed by land suitability. The results showed that the waters of Obi Island have the potential for the development of Whiteleg shrimp cultivation based on the observed water quality parameters. This study concludes that the waters of Obi Island, South Halmahera Regency, North Maluku Province can be used to develop Whiteleg shrimp farming. The location of the waters has the criteria of suitability is very suitable for the cultivation of Whiteleg shrimp. Keywords : Penaeus vannamei, Obi Island, water quality.
