Abstract

Masyarakat yang mendiami wilayah pesisir cenderung membuang limbah sehingga limbah buangan tersebut mengalami proses dekomposisi dan menghasilkan emisi gas metana yang dapat memicu pemanasan global. Oleh karena itu, riset ini perlu untuk dilakukan dalam upaya menganalisis konsentrasi gas metana dari limbah yang dihasilkan masyarakat yang bermukim di wilayah pesisir. Penelitian ini dilakukan pada bulan Juli 2022 di kawasan pemukiman wilayah pesisir Kelurahan Watolo, Kecamatan Mawasangka, Kabupaten Buton Tengah, Provinsi Sulawesi Tenggara. Stasiun penelitian terdiri dari dua kawasan yaitu kawasan padat pemukiman (PP) dan kawasan jarang pemukiman (JP). Pengambilan sampel gas dilakukan dengan meletakkan sungkup pada substrat di kawasan pemukiman masyarakat pesisir. Analisis konsentrasi gas menggunakan metode GC-MS. Hasil penelitian menunjukkan bahwa total rata-rata konsentrasi gas metana pada kawasan padat pemukiman sebesar 1,93 ppm dan pada kawasan jarang pemukiman sebesar 1,79 ppm. Hasil uji anova menunjukkan perbedaan yang nyata antara konsentrasi gas metana di kawasan PP dengan kawasan JP. Perbdaan tersebut dipengaruhi oleh karakterisitik sedimen pada masing – masimg kawasan. Pada kawasan PP didominasi sedimen pasir berlumpur, sedangkan JP didominasi oleh sedimen pasir. Sedimen pasir berlumpur terbentuk karena adanya endapan bahan organik dari limbah yang dibuang oleh masyarakat di kawasan pada pemukiman seperti sisa makanan dan limbah domestik lainnya.

Abstract

Lamun (Seagrass) merupakan satu-satunya tumbuhan berbunga yang dapat hidup terendam sempurna di perairan laut. Spesies lamun yang ditemukan hidup di perairan Indonesia sebanyak 14 spesies. Pulau Maginti merupakan salah satu pulau kecil yang terletak di kawasan perairan Selat Tiworo Kabupaten Muna Barat yang memiliki ekosistem lamun yang belum dieksplor, oleh karena itu perlu dilakukan penelitian tentang jenis dan tutupan lamun di kawasan tersebut. Penelitian ini dilakukan pada bulan Desember 2022 di Perairan Pulau Maginti. Stasiun penelitian terdiri atas dua yaitu wilayah utara untuk stasiun 1 dan wilayah selatan untuk stasiun 2. Pengambilan data lamun menggunakan metode transek garis dan transek kuadrat. Pengambilan data dilakukan pada 5 transek. Setiap transek memiliki panjang 90 m ke arah laut dengan jarak antar transek 50 m dan jarak masing-masing kuadrat dalam 1 transek sebesar 10 m. Pengamatan kondisi lamun menggunakan frame kuadrat dengan ukuran 50 cm x 50 cm. Penentuan awal transek berdasarkan lamun yang pertama kali ditemukan pada lokasi penelitian (0 m). Data selanjutnya dianalisa untuk memperoleh persentasi tutupan lamun pada masing-masing stasiun, persentase tutupan per jenis lamun, serta persentase frekuensi kehadiran per jenis lamun. Berdasarkan hasil penelitian ditemukan sebanyak 5 spesies yang terdiri dari Enhalus acoroides, Thalassia hemprichii, Halodule pinifolia, Halodule uninervis, Halophila minor. Pada kedua stasiun pengamatan ditemukan persentasi tutupan lamun pada stasiun 1 sebesar 57.50%, sedangkan persentasi tutupan pada stasiun 2 64,31%, sehingga total tutupan lamun pada Pulau Maginti sebesar 60,90%. Berdasarkan nilai total tutupan lamun, dapat disimpulkan bahwa tutupan lamun di Pulau Maginti termasuk dalam kategori padat.

Abstract

Mangroves are plants that live on the coast and are affected by sea tides. Mangroves play an important role in estuary areas, namely the border between seawater and fresh water because they have ecological, economic and chemical functions to support the life of organisms. Mangrove ecosystems can experience threats from both natural and human factors. Human activities that cause damage to mangroves are due to a lack of public awareness regarding the importance of mangrove ecosystems for organisms. This is the condition that occurs in the mangrove ecosystem in Waai Village, therefore, it is necessary to restore the mangrove ecosystem. Mangrove ecosystem restoration uses one of the potential media, namely BESE-Element, which is a biodegradable material. Community service is carried out in collaboration with the Pattimura University Maritime Center and Wardenburg Ecology International. The community service activities were carried out for two days, 7-8 February 2023. The result of the activity was that mangrove ecosystem restoration was carried out in semi-enclosed areas using 10 BESE-Element. The types of mangrove species planted were Sonneratia alba, Rhizophora stylosa, and Ceriops tagal. Around BESE-Elements planted seedlings and mangrove propagules as a control for mangroves in BESE-Elements. This restoration activity seems to be applicable not only in Waai Village but also in other areas that have experienced degradation of the mangrove ecosystem.

Abstract

Contaminants entering marine systemts have become environmental issues because of their significantly negative impacts. Coasts of Rumah Tiga Village are connected to Ambon Bay and provide marine habitats and tourist attractions due to their location close to Merah Putih Bridge (including recreations, restaurants and aquaculture sites). These human related activities contribute to the discharge of wastes into marine waters. Due to their location at inshore outer Ambon Bay, marine pollutants from the bay tend to be applied at the location. Because of the concentrated pollutants at the location, the coasts of Rumah Tiga Village are a suitable location to conduct beach clean-ups in Ambon Bay. The beach clean-up activities also aim to allow Study Program of Marine Science of Faculty of Fisheries and Marine Sciences, Pattimura University to raise awareness to its students and local community to care for environment.
