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

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.

Abstract

Gold reserves on Gunung Botak (Bald Mountain), Buru Island, were discovered in 2011. Since then, thousands of illegal miners have used amalgamation methods to extract gold in the areas of Gunung Botak and Gogrea, Buru Island. The resulting waste is disposed of into the environment directly without any treatment process so it is very dangerous for humans and the environment. This research was conducted to determine the ability of the Enhalus acoroides type of seagrass to accumulate heavy metal mercury (Hg) in the aquatic environment. This research shows that the heavy metal mercury has been distributed in the water sediments along Kayeli Bay. Mercury bio-concentration (accumulation) Gunung Botak, Kayeli Bay, Mercury (Hg), bioconcenstration, Seagrass, Enhalus acoroides, Kayeli Baywas found in Enhalus acoroides seagrass, in leaves (0.0243-0.0373 mg/Kg), and in rhizomes (0.0453-0.0663 mg/Kg). This result shows that the Kayeli Bay ecosystem has been contaminated with mercury.

Abstract

Utilization of the mangrove ecosystem in West Muna Regency is widely used as firewood, building materials, and other infrastructure development. This utilization has an impact on reducing the area and density of the mangrove ecosystem, thereby reducing the functions and benefits of the mangrove ecosystem. Community participation is very necessary in the sustainable management of mangrove ecosystems. This can happen if the government and the community understand well about the functions and benefits of the mangrove ecosystem for people's lives. This community service activity is a form of independent service as an effort to apply knowledge to advance people's lives through sustainable mangrove ecosystem management. The socialization was carried out using a discussion method with the village government and key figures who played a role in policy making in Latawe Village, West Muna Regency. This service activity provides a deep understanding to the community regarding the introduction of mangrove species, the benefits and importance of conserving the mangrove ecosystem. This is indicated by the follow-up from the village government and community leaders to rehabilitate mangroves on critical lands by involving the full participation of the community. The acquisition of seeds for rehabilitation is carried out independently by the community with funding assistance from the Ministry of Marine Affairs and Fisheries through the Directorate General of Marine Spatial Management and Small Islands. Service activities will continue by continuing to provide direct and indirect assistance in rehabilitation activities starting from determining the location, selecting seeds, sowing seeds, and rehabilitation techniques

Abstract

Mangrove ecosystems play a significant role in carbon absorption. However, the accumulation of organic matter in mangrove sediments undergoes decomposition, which triggers the release of CO2 gas flux. This study aimed to analyze the CO2 gas flux in mangrove sediments of Negeri Passo, Ambon City. Gas data collection was performed using cylinder canopies at the three observation stations. Gas was passed through the syringe five times with an interval of 30s. Gas concentration analysis was carried out using the gas chromatography method, while CO2 flux was analyzed with flux equations referring to slope regression, volume and area of the scope, temperature, molecular weight of the gas, ideal gas settings, and time constants based on gas intake intervals. The results showed that the average CO2 concentration in St. 1 was 465.14 ± 96.52 ppm, and was the lowest compared to St. 2 and St. 3 with values of 638.60 ± 90.05 ppm and 630.98 ± 54.09 ppm, respectively. Meanwhile, the average CO2 flux was 50.44 mg/m2/hour. The largest CO2 gas flux was observed at St. 2 at 103.69 mg/m2/hour. Meanwhile, the lowest flux was found at St. 3, which was 16.24 mg/m2/hour. Based on this, it can be concluded that] the mangrove ecosystem in Negeri Passo has a higher concentration of CO2 gas than the average concentration of climate change stabilization scenarios. However, the CO2 flux was lower than that at other locations in the Ambon Dalam Bay area. In addition, the potential for significant carbon sequestration based on the Tier 1 model approach indicated that mangrove ecosystems in this location play an important role in climate change mitigation.
