Abstract

Water quality is very vital to support the survival of organisms. Determination of water quality status needs to be carried out as a reference for monitoring water pollution of an aquatic system. This study aims to assess the status of water quality in the Gorontalo Bay. There are 5 observation stations selected based on the coastal conditions and ecological characteristics. Sampling of water quality parameters was conducted along the Gorontalo Bay in May to July 2017. Sampling procedure based on APHA standard method. The water quality data are analyzed using Pollution Indeks method. Gorontalo Bay has Pollution Index average score of 4.74. This value shows that the quality status of the Gorontalo Bay is considered as polluted category.

Abstract

Human activities in the watershed in the upstream of Cileungsi river have tendency to bring high organic materials to the river which determines the aquatic condition of the river. The decreased water quality is event because of the organic materials in the upstream of Cileungsi river would bring negative impacts towards water condition in the downstream. This study was conducted in determining the water quality in the upstream of Cileungsi river, using Trophic Diatom Index (TDI). The sampling was taken in four different sites in the river and sub-river of the upstream of the river. The sampling of ephilitic diatom organisms were taken by scraping the surface of substrate rocks using brush then soaked the materials into a sampling bottle which hasbun containing destile water. Diatom density was measured using census method according to standard of APHA 2012. The TDI score ranged from 48.25 to 60.47, indicating that the water quality of upstream of Cileungsi river is classified from good until poor condition.

Abstract

Good water quality is extremely important to support life of organisms. The determination of water quality status was needed as reference to monitor water pollution in aquatic system. This study aimed to assess the status of water quality in the Gorontalo Bay. There ware five sampling sites which represented the coastal condition and ecological characteristic. Sampling was carried out in May-July 2017. Sampling procedure of water samples carried out based on APHA standard method. Existing water quality data was analyzed by using STORET method. The result showed that Gorontalo bay obtained total score -39. It means the status of water quality the Gorontalo bay during sampling period in bad category. Kondisi kualitas air suatu perairan yang baik sangat penting untuk mendukung kelulushidupan organisme yang hidup di dalamnya. Penentuan status mutu air perlu dilakukan sebagai acuan dalam melakukan pemantauan pencemaran kualitas air suatu sistem akuatik. Penelitian ini bertujuan untuk mengkaji status mutu air di perairan Teluk Gorontalo. Terdapat 5 stasiun pengamatan yang dipilih berdasarkan kondisi pantai dan karakteristik ekologi Teluk Gorontalo. Pengambilan sampel parameter kualitas air dilakukan di sepanjang perairan Teluk Gorontalo pada bulan Mei-Juli 2017. Prosedur pengambilan sampel berdasarkan metode baku APHA. Data kualitas air yang ada kemudian akan dianalisis dengan menggunakan Metode STORET. Hasil penelitian menunjukkan bahwa Teluk Gorontalo memperoleh total skor -39. Hal ini menunjukkan status mutu Teluk Gorontalo di bulan Mei-Juli tergolong dalam kategori buruk.

Abstract

Abstrak. Penelitian ini bertujuan menentukan status mutu kualitas air di bagian hulu Sungai Cileungsi serta membandingkan beberapa parameter kualitas air dengan baku mutu kelas II berdasarkan PP RI No.82 Tahun 2001. Penelitian dilakukan bulan September, Oktober dan November 2013 pada empat stasiun pengambilan contoh di bagian hulu Sungai Cileungsi. Data hasil penelitian dianalisis mengggunakan Indeks Kualitas Air-NSF serta secara deskriptif dibandingkan dengan baku mutu kelas II menurut PP RI. No.82 tahun 2001. Hasil penelitian (Suhu air: 23 – 29,3 oC; pH: 6; Oksigen Terlarut: 6,23 - 6,88 mg/L; DHL: 139,6 - 186,3 µS/cm; Kekeruhan: 4,77 - 41,8 mg/L; TDS: 70 - 94 mg/L; TP: 0,026 - 0,099 mg/L; Ortofosfat 0,002 mg/L; Nitrat: 0,36 - 0,959 mg/L) menunjukkan kualitas perairan yang masih memenuhi baku mutu. Sedangkan untuk parameter (BOD5: 3,97 - 5,7 mg/L; COD: 14,68 - 48,06 mg/L) menunjukkan nilai yang telah melampaui ambang batas baku mutu kelas II PP RI. No.82 tahun 2001. Namun, secara keseluruhan hasil analisis dengan menggunakan IKA-NSF menunjukkan bahwa kualitas air di semua stasiun memiliki kualitas perairan yang baik dengan rentang skor 78 - 83.Kata kunci : Sungai Cileungsi; Kualitas Air; Pencemaran

Abstract

Nike fish is one of the fish species found in Gorontalo known to belong to the Gobiidae group. Nike is fishing intensively by local fishermen without considered sustainability aspect. Unfortunately, the comprehensive scientific data for the management purposes of nike fish was not yet available. Therefore, this study aims to assess the period of occurrence of nike fish in the Gorontalo Bay as the initiation of providing scientific information that supports sustainable management goal. Sampling was conducted from March to June 2018 using fish net. The results showed that the period of occurrence of nike fish every month starting from the bay area and move toward the estuary. The emergence of nike fish that began in the eastern part of Gorontalo Bay occurred in March, April, and May 2018. While the appearance of nike fish that started from the western area of the bay occurred in June and July 2018. It was concluded that the duration of occurrence of nike fish in the Gorontalo Bay occurs for 3 to 9 days at the end of the lunar phase.Nike merupakan salah satu spesies ikan yang ditemukan di Perairan Gorontalo yang dikenal berasal dari kelompok gobiidae. Kegiatan eksploitasi ikan nike oleh nelayan belum mempertimbangkan aspek kelestariannya di perairan berpotensi mengancam keberlanjutannya di perairan. Data ilmiah dan komprehensif yang dapat dijadikan acuan pengelolaan ikan nike belum tersedia. Oleh karena itu, penelitian ini bertujuan untuk memetakan periode kemunculan ikan nike di perairan Teluk Gorontalo sebagai inisiasi penyediaan informasi ilmiah yang mendukung arah pengelolaan yang berkelanjutan. Pengambilan sampel ikan di Perairan Teluk Gorontalo dilakukan pada Bulan Maret sampai Juni 2018 dengan menggunakan jaring ikan. Hasil penelitian menunjukkan bahwa periode kemunculan ikan nike setiap bulan dimulai dari area teluk dan begerak ke arah muara. Kemunculan ikan nike yang dimulai di perairan Teluk Gorontalo bagian timur terjadi pada bulan Maret, April, dan Mei 2018. Sedangkan kemunculan ikan nike yang dimulai dari area barat teluk terjadi pada bulan Juni dan Juli 2018. Secara keseluruhan, durasi kemunculan ikan nike di perairan Teluk Gorontalo terjadi selama 3 sampai 9 hari di fase bulan akhir menjelang bulan baru.

Abstract

Investigating goby fish is vital to perform an integrated and comprehensive study in order to maintain the roles of the fish, thus providing balanced ecosystem functions and services, as well as contributing to fish biodiversity. Local societies simply recognize fish species by their local names, which are not common. This condition, in turn, causes hitches in conducting further studies. Nike, the name of a local fish, refers to the schools of goby fish larvae whose adult phase has not been fully confirmed. This study aimed to reveal the species that categorizes as nike fish through tracing adult goby inhabiting freshwater. Two fish samples, i.e., Unknown 01 and Unknown 02, were taken from two sites in Bone River, Gorontalo, Indonesia. These samples were captured purposively using a hand net by considering the morphological similarity between the two target samples and the general characteristic of goby. Furthermore, the samples were analyzed genetically through the PCR sequencing method using the Mitochondrial Cytochrome Oxidase Subunit 1 (CO1) gene. Based on the NCBI database, Unknown 01 had the highest similarity to Belobranchus belobranchus (99.54%), while Unknown 02 was identical with Awaous ocellaris (100%). Unknown 01 and Unknown 02, compared to the BOLD database, the similarity level, had the highest percentage of similarity with B. belobranchus (99.85%) and A. ocellaris (100%), respectively. Therefore, A. ocellaris and B. belobranchus were strongly alleged as two species making up the goby schools in the adult stadia that reach freshwater during their migration.
