Abstract

Selama dekade terakhir ini, informasi tentang kejadian mamalia laut terdampar cukup sering terjadi di Indonesia, salah satunya di wilayah Sulawesi Barat. Kecepatan dan ketepatan dalam melakukan tindakan penanganan sesuai dengan kondisi mamalia laut (hidup atau mati) dapat memberikan banyak informasi yang akan berguna dalam melakukan pengelolaan pesisir dan laut. Penelitian ini bertujuan untuk menyusun basis data dan informasi sebaran dan teknik penanganan kejadian mamalia laut terdampar di Sulawesi Barat. Studi dilakukan melalui pengumpulan data secara langsung saat penanganan mamalia laut terdampar selama periode tahun 2022 – 2024. Data tersebut selanjutnya ditabulasi dengan Microsoft Excel dan dianalisis secara deskriptif kualitatif berdasarkan kode terdampar, selanjutnya dilakukan analisis secara spasial dengan bantuan software ArcMap untuk memvisualisasikan sebaran kejadian mamalia terdampar. Berdasarkan data penanganan mamalia laut terdampar selama periode tahun 2022 s/d 2024 di Sulawesi Barat, terdapat 4 kejadian mamalia laut terdampar diantaranya di Kabupaten Mamuju sebanyak 2 ekor, Kabupaten Pasangkayu sebanyak 1 ekor dan Kabupaten Polewali Mandar sebanyak 1 ekor, dengan total mamalia laut terdampar sebanyak 4 ekor. Seluruh mamalia laut tersebut terdampar dalam kondisi mati yaitu kode 2, 3, dan 4. Teknik penanganan yang dilakukan terhadap mamalia laut yang terdampar selama tahun 2022-2024 di Sulawesi Barat adalah dengan cara ditenggelamkan dan dikubur.

Abstract

Land use around the river, can affect the condition water quality of waters. The purpose of this study are to determine the pollution index and the rate of river sedimentation, and land use around the Banjir Kanal Barat and Silandak River. The method for sampling was purposive sampling. Sampling was carried out in the Banjir Kanal Barat and Silandak River, each of which had 5 points and 2 repetitions (P1 and P2). The variables analyzed were TSS, BOD, COD, total coliform where analyzed with Indonesian Standard National (SNI); DO, pH, temperature, discharge of water analyzed with Water Quality Checker (WQC), Buchanan method used to analyzed sedimentation rate, and sediment fraction. The results of the study, showed that IP in the Banjir Kanal Barat River obtained an IP value of 4.13 (lightly polluted), while the Silandak River obtained an IP value of 4.69 (lightly polluted). The highest sedimentation rate in the Banjir Kanal Barat River with a value of 35.64 tons / day, while the Silandak River has the highest value of 55.81 tons / day. Sediment fraction in Banjir Kanal Barat River is dominated by clay, and Silandak River it is dominated by clay. Land cover in Banjir Kanal Barat river are 3% industry, 85% settlement, 0% water and 12% vegetation, and Silandak River are 7% industry, 69% settlement, 5% water and 7% vegetation.

Abstract

Kedung Ombo Reservoir is one of the reservoirs in Central Java which is used for irrigation, tourism, and aquaculture activities. Common problems in reservoir waters are nutrient enrichment by organic waste from fish feed and other sources. The aim of this study was to evaluate the level of water suitability based on water quality. This study was conducted in June-August 2023. Sampling was carried out at three stations with different floating net cage densities. The water quality variables measured included dissolved oxygen (DO), temperature, pH, transparency, turbidity, ammonia, biochemical oxygen demand (BOD), nitrate, phosphate, and chlorophyll-a. Evaluation of the water suitability for floating net cage waters in Kedung Ombo Reservoir was determined by a weighting matrix and water suitability index. The water suitability evaluation of floating net cages in three stations was categorized as suitable. All variables were suitable except BOD at all stations and DO in stations 1 and 3.Keywords:Dissolved oxygenFloating net cageKedung Ombo ReservoirSuitabilityWater quality

Abstract

Dredging  Segara  Anakan  lagoon  that  have  been  implemented  in  1997  -     2005,  has  given  rise  to  the consequences of new land from the dredging is often referred as Ex-Disposal Area. Along with the increasing socio-economic problems, this land is considered as a strategic area for use as aquaculture lands. Milk Fish (Chanos chanos) and Crab (Scylla sp) are comodity targets,that wants develop as silvofisheries program. This study aimed to determine the location and potential areas as aquaculture lands based on a suitability analysis.  The research method was descriptive case study, in which a purposive sampling technique was applied to collect the samples,  including 2 sampling periods (rainy and dry season). The location in this research was Ex Disposal Area (EDA), consist of Klaces, Panikel  and  Ujunggagak  district. Research  variabel  were  soil  quality,  water quality  and  EDA’s  environment parameters. Spatial analysis data used GIS, that was proccessed by ER Mapper 7.0 and ArcGIS 9.3 software. The concept of suitability level by scoring method combining values and weight matrix. Result of research yielded that potential land for fisheries activity (brakish water ponds)  were : moderately suitable class (S2) that was 5.309,05 m2, at  Panikel and  Ujunggagak districs; marginally suitable class (S3) is 77.325.77 m2, not suitable for present time class (N1) that was 1.365.955,67 m2, and permanently unsuitable class (N2) is 7.583.809,51 m2. Coverage area of class S3,N1 and N2 included Panikel, Klaces and Ujunggagak. Keywords : Land Use, Ex Disposal Area (EDA), Ponds, Geography Information System (GIS)

Abstract

Ekosistem mangrove memiliki peran strategis dalam menjaga stabilitas wilayah pesisir, baik dari aspek ekologis, ekonomis, maupun sosial. Meningkatnya aktivitas antropogenik seperti permukiman, pariwisata, dan perikanan menyebabkan akumulasi sampah laut yang mengancam keberlanjutan ekosistem mangrove. Kepulauan Karimunjawa sebagai kawasan konservasi mengalami tekanan akibat polusi sampah laut yang terperangkap di sistem perakaran mangrove. Penelitian ini bertujuan untuk mengidentifikasi jenis dan komposisi sampah laut, menghitung kepadatan, serta memetakan distribusi spasialnya pada ekosistem mangrove. Penelitian dilakukan pada dua lokasi dengan karakteristik yang berbeda, menggunakan metode line transect berdasarkan zonasi pertumbuhan mangrove (seaward, middle, dan landward). Pengolahan data mencakup uji independent samples t-test, regresi polinomial, serta analisis spasial menggunakan citra satelit Sentinel-2A. Hasil Penelitian menunjukkan sampah plastik merupakan jenis dominan (65,86%), diikuti oleh styrofoam (20%) dan karet (9,81%). Lokasi mangrove dekat permukiman memiliki kepadatan sampah yang signifikan lebih tinggi dibandingkan kawasan wisata (p < 0,05). Sampah laut terkonsentrasi pada zona seaward (92,88%) dan menunjukkan hubungan kuat dengan jarak pengambilan sampel dari pantai (R² = 0,83). Vegetasi mangrove yang ditemukan di lokasi penelitian terdiri atas Rhizophora sp., Sonneratia sp., Ceriops sp., dan Lumnitzera sp. yang memiliki karakteristik perakaran berbeda dan berperan dalam proses penjebakan sampah. Penelitian ini memberikan kontribusi dalam penyusunan strategi mitigasi berbasis spasial untuk perlindungan ekosistem mangrove dari tekanan limbah padat.
