Abstract

Tujuan penelitian ini adalah untuk mengetahui komposisi dan pola sebaran lamun di Perairan Laut Sulawesi Desa Garapia Kecamatan Monano Kabupaten Gorontalo Utara. Penelitian ini dilaksanakan pada Bulan September 2015 sampai Februari 2016. Metode yang digunakan adalah metode kuadran berukuran 1x1 meter. Lokasi penelitian dibagi menjadi 2 stasiun yaitu stasiun I (berdekatan dengan muara sungai dan pangkalan perahu) dan stasiun II (berdekatan dengan hutan mangrove). Komposisi jenis lamun di perairan Desa Garapia adalah Enhalus acoroides (13,29% dan 92,18%), Cymodoceae rotundata (46,43% dan 2,63%), Thalassia hemprichi (8,77% dan 2,86%), Halophila ovalis (18,26% dan 2,34%), Syringodium isoetifolium (13,25% dan 0%). Jenis lamun di perairan Laut Sulawesi Desa Garapia pada stasiun I untuk semua jenis lamun pola sebarannya mengelompok. Pada stasiun II, pola sebaran lamun terbagi atas beberapa kelompok yaitu: Pola sebaran seragam ditemukan pada Cymodocea ratundata dan Thalassia hemprichii, Pola sebaran acak terdapat pada Halophila ovalis, dan pola sebaran mengelompok terdapat pada Enhalus acoroides. Composition and distribution of seagrass in Garapia Village. The purpose of this study was to determine the composition and pattern of seagrass distribution in the Sulawesi Sea of Garapia Village, Monano District, North Gorontalo Regency. This research was conducted in September 2015 to February 2016. The method used was a quadrant method measuring 1x1 meters. The research location was divided into 2 stations, namely Station I (adjacent to the river mouth and boat base) and Station II (adjacent to the mangrove forest). The composition of seagrass species in the waters of Garapia Village are Enhalus acoroides (13.29% and 92.18%), Cymodoceae rotundata (46.43% and 2.63%), Thalassia hemprichi (8.77% and 2.86%), Halophila ovalis (18.26% and 2.34%), Syringodium isoetifolium (13.25% and 0%). Seagrass species in the Sulawesi Sea, Garapia Village at Station I, for all types of seagrass, the distribution patterns are clustered. At Station II, seagrass distribution patterns are divided into several groups, namely: uniform distribution patterns found in Cymodocea ratundata and Thalassia hemprichii, random distribution patterns found on Halophila ovalis, and clustered distribution patterns found in Enhalus acoroides.

Abstract

The purpose of this study was to determine the content of heavy metal mercury (Hg) in Limboto Lake waters. Sampling was conducted at 5 stations, namely Station 1 (estuary of the Biyonga River), Station 2 (estuary of the Alopohu River), Station 3 (floating net cages), Station 4 (non KJA) and Station. 5 (Outlet at Sungai Tapodu). Sampling both at the surface and the bottom of the water is only done once. Analysis of the content of mercury (Hg) was carried out at the Gorontalo Province Fishery Product Quality Development and Testing Laboratory (LPPMHP). The results showed that the mercury (Hg) content in Limboto Lake waters for Station 1 in the water samples taken was 0.027 mg / L, the sediment samples were 13.61 mg / L, for Station 2 namely water sample 0.013 mg / L and sediment sample 12.27 mg / L, Station 3, namely water sample 0.003 mg / L sediment sample 8.35 mg / L, while Station 4, namely water sample 0.0142 mg / L sediment sample 7.71 mg / L and for Station 5, water sample 0.016 mg / L sediment sample 6.79 mg / L. The condition of the heavy metal content of mercury (Hg), based on water quality standards of 0.001 mg / L and sediment quality standards of 0.2 mg / L, on average, has exceed the maximum limit, namely the level of mercury in the water is 0.0146 mg / L (> 0.001 mg / L) and the mercury level in the sediment was 9,746 mg / L (0.2 mg / L).

Abstract

The increasing of sea level due to climate change has been focused many research activities in order to know the coastal response to the change, and determine the important variables which have contribution to the coastal change. This paper presents a method for integrating Coastal Vulnerability Index (CVI), Multi Criteria Analysis (MCA) method and Geographic Information-System (GIS) technology to map the coastal vulnerability. The index is calculated based-on six variables: coastal erosion, geomorphology, slope, significant wave height, sea level change and tidal range. Emphasize has been made to the methodological aspect, essentially which is linked to: (i) the use of GIS technique for constructing, interpolation, filtering and resampling the data for shoreline grid, (ii) the standardization each rank of variables (0-1) and the use of several percentile (20%, 40%, 60%, and 80%) for each rank score, and (iii) the use of variable’s rank to map the relative (local) and standard (global) vulnerability of the coastline. The result show that for local, the index consist of four categories: very high (19.61%), high (68.63%), moderate (1,96%), and low (9.80%). Meanwhile, for global level, the index is constantly in low category.

Abstract

Data DKP Gorontalo hingga akhir tahun 2015 menunjukkan bahwa total luas mangrove dipesisir Gorontalo Utara mengalami kerusakan seluas 1.107,93 ha (35.9% total kerusakan).Meskipun data penginderaan jauh dapat menyediakan infromasi berguna mengenai perubahantutupan dan atau penggunaan lahan, teknik ini memiliki keterbatasan pada beberapa kawasanmangrove sempit (kecil) seperti mangrove di pesisir Gorontalo Utara. Terkait hal tersebut,penelitian ini mencoba menggali informasi kerusakan mangrove yang terjadi berdasarkanpengetahuan masyarakat local untuk memahami gangguan yang berlangsung, berupa persepsimereka terhadap kerusakan mangrove di wilayahnya. Tujuan penelitian adalah menelusuribeberapa bentuk produk manfaat mangrove, sejalan dengan persepsi mereka terhadap perubahanlingkungan. Pengumpulan data dilakukan melalui teknik wawancara dan observasi lapangmelalui wawancara rumah tangga dan observasi lapangan. Kesipulan penelitian menyorotikebutuhan untuk diseminasi pemahaman tentang mangrove dan manfaatnya yang berkelanjutanuntuk program rehabilitasi yang telah ada.Kata Kunci: Perubahan lahan, konversi mangrove, tambak, lahan pertanian, etnobotani
