Abstract

Global warming represents a significant challenge, primarily driven by the escalating concentrations of greenhouse gases in the atmosphere, notably carbon dioxide (CO₂). Mangrove ecosystems are integral to climate change mitigation due to their capacity to sequester and store carbon within their biomass and sediment. This study sought to evaluate carbon sequestration through the analysis of organic carbon content in the sediments of mangrove ecosystems located in Ampekale, Maros Regency. Sampling was executed using a purposive sampling method across nine sites, employing a 50 × 5 cm corer. Each sediment sample was sectioned into five depth intervals (0-10 cm, 10-20 cm, 20-30 cm, 30-40 cm, and 40-50 cm). The organic carbon content was assessed using the loss on ignition (LOI) method, with parameters measured including bulk density, sediment organic carbon concentration, carbon storage, and carbon uptake in sediments. Statistical analyses were conducted utilizing one-way and two-way ANOVA tests. The findings indicated that the mangrove ecosystem in Ampekale exhibited a total carbon storage in sediments of 731.72 tons/ha, with a total carbon uptake of 2685.42 tons/ha. The greatest carbon storage and uptake were observed at the 40-50 cm depth, with values of 342.056 tons/ha and 1255.34 tons/ha, respectively.

Abstract

This study analyzed the composition and density of mangrove species in Borong Kalukua and Bonto Bahari in Maros Regency. The research method involved a field survey using purposive sampling in several observation plots. The data obtained were analyzed using a quantitative descriptive method to calculate the averages and standard deviations. The results showed that the mangrove density in Borong Kalukua was higher than that in Bonto Bahari, with average densities of 450 and 350 trees/ha, respectively. The standard deviation value showed variations in density between plots, with Borong Kalukua showing more significant variation than Bonto Bahari. Environmental factors and anthropogenic pressures are considered the primary causes of these differences. This study highlights the importance of conservation and rehabilitation efforts in maintaining the balance of mangrove ecosystems, particularly in areas subjected to higher environmental pressures.

Abstract

Seaweed is one of the leading fishery commodities in the coastal areas of South Sulawesi, with high economic potential. However, its utilization is still predominantly limited to the sale of raw products, resulting in limited economic value added for local communities. This Community Service Program was conducted to promote seaweed product diversification through the development of value-added food products, namely seaweed-based noodles and nuggets. The activity was carried out on May 10, 2025, in Borongkalukua Hamlet, Borimasunggu Village, Maros Baru District, Maros Regency, involving coastal communities as the main participants. The implementation methods included educational sessions, demonstrations and hands-on processing practices, as well as product packaging training. Evaluation was conducted using pretest and posttest approaches to describe changes in participants' responses regarding their knowledge, technical understanding of processing, and motivation. The results showed an increase in the percentage of positive responses across most measured indicators. Participants' knowledge increased from 5–15% before the training to 60–80% after the training, while motivation increased from 45–65% to 75–93%. Overall, the program indicated an improvement in the community's understanding of utilizing seaweed as a value-added product and increased participants' interest in developing local resource-based economic activities. This program has the potential to support capacity strengthening among coastal communities and promote the more sustainable utilization of marine resources.Rumput laut merupakan komoditas perikanan unggulan di wilayah pesisir Sulawesi Selatan yang memiliki potensi ekonomi tinggi, namun pemanfaatannya masih didominasi oleh penjualan dalam bentuk mentah sehingga nilai tambah ekonomi yang diperoleh masyarakat masih terbatas. Kegiatan Pengabdian kepada Masyarakat ini dilaksanakan sebagai upaya mendorong diversifikasi produk rumput laut melalui pengolahan menjadi produk pangan bernilai tambah berupa mie dan nugget. Kegiatan berlangsung pada tanggal 10 Mei 2025 di Dusun Borongkalukua, Desa Borimasunggu, Kecamatan Maros Baru, Kabupaten Maros, dengan melibatkan masyarakat pesisir sebagai peserta utama. Metode pelaksanaan meliputi penyuluhan, demonstrasi dan praktik langsung pengolahan, serta pelatihan pengemasan produk. Evaluasi dilakukan menggunakan pretest dan posttest untuk menggambarkan perubahan respons peserta pada aspek pengetahuan, pemahaman teknis pengolahan, dan motivasi. Hasil kegiatan menunjukkan adanya peningkatan persentase respons positif pada sebagian besar indikator yang diukur. Pengetahuan peserta meningkat dari 5–15% sebelum pelatihan menjadi 60–80% setelah pelatihan, sedangkan motivasi meningkat dari 45–65% menjadi 75–93%. Secara umum, kegiatan ini mengindikasikan adanya peningkatan pemahaman masyarakat terhadap pemanfaatan rumput laut menjadi produk bernilai tambah serta meningkatnya ketertarikan peserta untuk mengembangkan aktivitas ekonomi berbasis sumber daya lokal. Program ini berpotensi mendukung penguatan kapasitas masyarakat pesisir dan pemanfaatan sumber daya laut secara lebih berkelanjutan.
