Abstract

Changes in water temperature impact the dynamics of lake ecosystems. Changing climate factors, including wind speed and air temperature, influence the water temperature of lakes. This research aims to analyze the response of water temperature to wind speed and air temperature in Lake Laut Tawar. Observations were conducted from August to September 2023, with a sampling frequency of every two weeks. The results revealed that water temperature, wind speed, and air temperature in Lake Laut Tawar fluctuated according to the presence of light, namely day and night factors. Variations in sunlight intensity lead to hourly fluctuations in air temperatures, while wind speeds vary hourly due to changes in air pressure, consequently resulting in hourly variations in water temperature as well. During daylight hours, air temperature surpasses water temperature, whereas during nighttime hours, water temperature exceeds air temperature. Heat transfer from the air to the water contributes to an increase in water temperature, while the release of heat energy from the surface water into the air leads to a decrease in water temperature. Changes in the water temperature of Lake Laut Tawar are primarily influenced by changes in wind speed and air temperature by 80 percent simultaneously. However, while air temperature showed a partial response, wind speed did not exhibit a significant response. The relationship between these variables can be expressed through a mathematical model Tw = 0.356 Ta + 0.025 W + 15.674, where Tw is water temperature (°C), Ta is air temperature (°C), and W is wind speed (km/minute). Another factor that influences the water temperature of Lake Laut Tawar is the inlet water temperature, which was not observed in this research.

Abstract

Marine debris consists of materials discarded or unintentionally introduced into the marine environment by human activities. The increasing volume of marine debris is largely attributed to human activity near coastal areas. Bluka Teubai Beach, North Aceh, a popular visitor destination, has a high potential for waste accumulation. This study, conducted in May 2024, employed a purposive sampling method to assess marine debris. The research area was divided into three stations with distinct characteristics, using the line transect method. Results from Bluka Teubai Beach identified two primary waste categories: organic and inorganic. Organic waste included wood, bamboo, and coconut husk, while inorganic waste consisted of plastic, glass, metal, and rubber. Among organic waste, wood exhibited the highest absolute density (0.456 items/m²) and relative density (53.950%), followed by bamboo (0.317 items/m², 39.641%) and coconut husk (0.049 items/m², 6.409%). The overall density of organic waste at Bluka Teubai Beach was highest for wood (0.23 items/m²), with an average relative density of 58.640%. For inorganic waste, plastic had the highest absolute density in pieces (2.24 items/m²) and relative density in pieces (96.968%). The highest absolute density and relative mass of inorganic waste were also found in plastic (99.94 g/m² and 64.36%, respectively). Temporal analysis revealed that organic waste accumulation peaked on Fridays, while inorganic waste was most abundant on Tuesdays in terms of count and on Sundays in terms of mass. The results underscore the urgent need for targeted waste management strategies and continuous monitoring to mitigate marine debris pollution and protect the coastal ecosystem of Bluka Teubai Beach.

Abstract

Dalam upaya memanfaatkan sumberdaya perikanan secara maksimal, maka perlu didukung dengan  engetahuan dan teknologi. Lokasi penangkapan ikan oleh nelayan Desa Cot Seurani cenderung tidak tepat karena umumnya hanya mengandalakan tanda-tanda alam, perasaan, dan faktor keberuntungan. Bahkan tidak jarang pula saat menurunkan alat tangkap (seperti jaring, pancing, dan lain-lain). Penggunaan teknologi yang tepat merupakan salah satu alternatif yang dapat memecahkan masalah penangkapan ikan. Salah satu teknologi yang dapat dimanfaatkan oleh nelayan adalah fish finder. Fish finder merupakan teknologi yang dapat mendeteksi objek bawah laut yang dengan memanfaatkan gelombang suara (akustik). Fish finder dapat memberikan informasi yang detail yaitu tentang kelimpahan, sebaran, dan posisi ikan, serta alat ini mampu memberikan data real time. Kegiatan pengabdian ini bertujuan untuk memberikan edukasi dan peningkatan keterampilan kepada nelayan khususnya kelompok nelayan desa cot seurani tentang manfaat penggunaan fish finder. Pengabdian ini menggunakan metode pendekatan community development (pengembangan masyarakat) melalui pelatihan berdasarkan teori dan praktik dengan ceramah serta diskusi yang terarah (Focus Group Discussion/FGD). Pelaksanaan pengabdian ini dimulai dengan survei lokasi, penandatanganan Kerjasama dengan kelompok nelayan dan pelatihan. Kegiatan pengabdian terlaksana dengan baik, terstruktur, lancar serta sukses, dimana pelaksanaan kegiatannya dilakukan dengan 2 sesi yaitu sesi teori dan sesi praktik. Dampak dari pengabdian ini nelayan mampu menggunakan Fish Finder dengan baik serta nelayan mengerti dan memahami hasil luaran (membaca layar) dari Fish Finder sehingga nantinya diharapkan mampu meningkatkan produksi perikanan tangkapan dan meningkatkan kesejahteraan kelompok nelayan.

Abstract

Sargassum sp merupakan jenis rumput laut yang tumbuh subur secara alami di perairan Indonesia, termasuk di Perairan Simeulue, Provinsi Aceh. Sargassum sp. mengandung berbagai senyawa bioaktif yaitu fenol yang berpotensi sebagai antioksidan. Sargassum sp. di Perairan Simeulue belum dimanfaatkan oleh masyarakat setempat dan belum ada laporan ilmiah tentang total fenol dan aktivitas antioksidan dari rumput laut tersebut. Tujuan penelitian ini menentukan aktivitas antioksidan dan total fenol Sargassum sp yang terdapat di Perairan Simeulue. Metode penelitian meliputi pengambilan sampel rumput laut, preparasi dan ekstraksi sampel rumput laut, uji fitokimia, analisis total fenol dan analisis aktivitas antioksidan rumput laut. Analisis data menggunakan analisis regresi linear untuk melihat hubungan total fenol dengan aktivitas antioksidan DPPH Sargassum. Hasil penelitian menunjukkan bahwa total fenol dan aktivitas antioksidan lima jenis rumput laut genus Sargassum (S. muticum, S. binderi, S. crassifolium, S. granuliferum, S. fluitans) di Perairan Simeulue menunjukkan nilai yang bervariasi. Total fenol 7,45-9,02 mg GAE/g dengan nilai tertinggi terdapat pada S. binderi dan nilai terendah pada S. fluitans. Aktivitas antioksidan 74,7-152,4 μg/mL dengan nilai tertinggi terdapat pada S. binderi, sedangkan nilai terendah terdapat pada S. fluitans. Hasil analisis korelasi (R2 = 0,9059) menunjukkan bahwa aktivitas antioksidan rumput laut genus Sargassum berhubungan erat dengan total fenol. Kelima spesies rumput laut Sargassum di Perairan Simeulue mempunyai aktivitas antioksidan yang kuat (74,7-152,4 μg/mL) sehingga berpotensi dikembangkan sebagai antioksidan.

Abstract

Meningkatnya konsentrasi karbondioksida (CO2) di atmosfer dapat menyebabkan asidifikasi laut. Asidifikasi menjadi ancaman bagi lamun. Salah satu tantangan yang harus dihadapi saat ini adalah memprediksi dampak jangka panjang dari asidifikasi laut terhadap fisiologi lamun. Tujuan penelitian ini untuk menganalisis respons fisiologis lamun C. rotundata yang meliputi kandungan klorofil a dan b, laju fotosintesis dan laju pertumbuhan daun lamun. Penelitian dilaksanakan pada bulan September – Desember 2017 di Laboratorium Marine Habitat Departemen Ilmu dan Teknologi Kelautan, Institut Pertanian Bogor. Metode yang digunakan adalah rancangan percobaan acak lengkap 5 pengulangan. Perlakuan pH yang digunakan yaitu pada nilai pH rendah (7,55), menengah (7,78) dan kontrol (8,20). Pengaturan nilai pH dengan cara menambahkan unsur CO32-. Kandungan klorofil a dan b, Laju fotosintesis dan Laju pertumbuhan daun C. rotundata perlakuan pH 8,20 lebih tinggi dibandingkan dengan perlakuan pH 7,78 dan pH 7,55. Uji ANOVA menunjukkan hanya klorofil a yang berbeda signifikan. Perbedaan pH mempengaruhi kandungan klorofil a dan b, laju fotosintesis dan laju pertumbuhan daun. Rendahnya pH air laut terbukti menghambat aktivitas fisiologis daun lamun C. rotundata.
