Abstract

Ekosistem laut rentan rusak akibat dari perubahan iklim, eksploitasi berlebih dan pencemaran laut. Kendala upaya konservasi adalah kurangnya pemahaman publik akan pentingnya melestarikan laut. Peningkatan pemahaman harus dilakukan di berbagai wilayah. Kesadaran siswa mengenai urgensi pelestarian ekosistem laut, dapat ditingkatkan melalui pendidikan yang bersifat interaktif dan berorientasi lingkungan. Kegiatan pengabdian ini bertujuan memberikan edukasi pemahaman ekosistem laut bagi siswa/i SDN 04 Moramo Utara bertema “Pahlawan Kecil Penjaga Laut”. Kegiatan ini berupa pengenalan dan pentingnya menjaga ekosistem laut. Metode yang digunakan presentasi, diskusi dan tanya jawab dengan semua anak didik kelas 1 sampai 6 SD yang berjumlah 136 Murid. Untuk menimbulkan rasa tanggung jawab terhadap ekosistem laut, kegiatan dilanjutkan dengan lomba menggambar yang diikuti oleh murid kelas 1 sampai 4 SD. Hasil kegiatan ini menunjukan bahwa siswa/i memiliki antusias yang tinggi terhadap topik ekosistem laut. Mampu menjelaskan fungsi dan kenapa kita harus menjaga laut serta memiliki rasa tanggung jawab akan kelestarian laut.

Abstract

Ekosistem pesisir khususnya vegetasi mangrove merupakan salah satu ekosistem yang rentan mengalami degradasi akibat perkembangan penggunaan ruang diwilayah pesisir. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk melakukan pendidikan lingkungan kepada generasi muda khususnya siswa sekolah, dan sebagai salah satu upaya untuk merestorasi ekosistem mangrove di pesisir Desa Bokori Kecamatan Soropia Kabupaten Konawe. Kegiatan ini dilakukan dalam beberapa tahapan, yakni penyampaian materi tentang pentingnya vegetasi mangrove dalam menopang sistem kehidupan di pesisir, dan praktek pembibitan mangrove dari jenis Rhizophora sp. Media tanam yang digunakan adalah tanah yang berasal dari lokasi pembibitan yang dikemas kedalam kantong polybag tanpa menggunakan tambahan pupuk organik maupun anorganik. Propagul mangrove disemai dengan cara ditancapkan kedalam polybag yang telah berisi media tanah dengan kedalaman ± 15 cm. Seluruh rangkaian kegiatan tersebut dilakukan oleh siswa sekolah yang berjumlah 30 orang. Hasil kegiatan pengabdian ini menujukkan bahwa propagul mangrove yang disemai tumbuh dengan baik.  Setelah ± 30 hari setelah penyemaian, propagul yang disemai telah memunculkan dua helai daun muda yang menandakan bahwa sistem perakaran mulai terbentuk. Hal ini menegaskan bahwa pelibatan generasi muda khususnya siwa sekolah cukup efektif dalam upaya rektorasi ekosistem pesisir , khususnya ekosistem mangrove.

Abstract

Degradasi ekosistem pesisir akibat perubahan tata guna lahan dan aktivitas antropogenik memerlukan intervensi strategis yang melibatkan berbagai pemangku kepentingan. Artikel ini mendokumentasikan kegiatan pengabdian kepada masyarakat yang diinisiasi oleh Fakultas Perikanan dan Ilmu Kelautan, Universitas Halu Oleo (FPIK UHO), dalam upaya restorasi ekosistem mangrove di pesisir Kecamatan Moramo, Kabupaten Konawe Selatan, Provinsi Sulawesi Tenggara. Metode pelaksanaan dilakukan melalui pendekatan partisipatif yang mengintegrasikan peran akademisi, pemerintah daerah, instansi militer (TNI-AL), dan masyarakat lokal. Hasil pengabdian menunjukkan bahwa melalui penanaman 6.000 bibit mangrove jenis Rhizophora sp. pada area seluas 0.6 hektar, dengan tingkat kelulushidupan (survival rate) mencapai 75% setelah enam bulan, serta partisipasi aktif lebih dari 200 individu dari berbagai elemen pentahelix, keterlibatan aktif civitas akademika FPIK UHO, yang didukung oleh kebijakan Pemerintah Kabupaten Konawe Selatan, mampu mempercepat proses rehabilitasi lahan kritis. Kegiatan ini tidak hanya berfungsi sebagai upaya konservasi biofisik, tetapi juga sebagai media edukasi ekologis dan penguatan kesadaran kolektif terhadap jasa ekosistem mangrove dalam mitigasi perubahan iklim dan perlindungan garis pantai. Data kuantitatif ini menegaskan keberhasilan intervensi dalam mencapai tujuan restorasi yang terukur.

Abstract

Nickel mining in Pomalaa, Southeast Sulawesi, potentially alters mangrove ecological dynamics, specifically affecting benthic biota. This study analyzes the population structure of the mangrove snail (Terebralia sulcata) using purposive systematic sampling across reference, transition, and mining-impacted zones. Data were collected via transect quadrat methods (5x5 m²) during January 2024–January 2025. Water quality analysis indicated significant elevations in dissolved Ni and organic loads (COD/BOD) in impacted areas. Population structure revealed a unimodal distribution dominated by the 35–45 mm class, with limited juvenile recruitment in stressed sites. The length-weight relationship (LWR) exhibited a strong negative allometric pattern (b = 2.02), indicating faster shell length growth as an adaptive response to environmental stressors. Despite a stable condition factor (Kn = 1.124), spatial disparities were evident through a progressive decline in density and biomass toward impacted stations. This study provides a significant scientific contribution by establishing T. sulcata as a sensitive bioindicator for nickel pollution. The findings emphasize that mining-derived stressors negatively correlate with biological performance, highlighting the necessity for policy-driven bioindicator monitoring and the integration of benthic health assessments into coastal management protocols within nickel industrial zones to mitigate long-term ecological degradation.

Abstract

This study aimed to determine the nitrogen content in the thallus of K. alvarezii in relation to filamentous algae attachment. The research location was determined using the purposive sampling method. This study used a horizontal net (horinet) as a cultivation tool. Sampling of K. alvarezii thallus was conducted over 35 days with a 7-day interval. A total of 20 thallus were collected during the study, consisting of 10 thallus with attached filamentous algae and 10 thallus without attached filamentous algae. The nitrogen content in the thallus was calculated using the Kjeldahl method, which involves three main stages: digestion, distillation, and titration. The results showed that the types of attached filamentous algae included one species from the class Chlorophyta, namely Chaetomorpha crassa, and one species from the class Rhodophyta, namely Neosiphonia apiculata. The highest average nitrogen content in the thallus when filamentous algae were attached was 1.121%, and the lowest was 0.863%. In contrast, in thallus without attached filamentous algae, the highest average nitrogen content was 1.274%, and the lowest was 0.942%. The results of the one-way ANOVA test analysis indicated no significant difference in nitrogen content between thallus with and without attached filamentous algae.

Abstract

The amount of plastic waste polluting Indonesia’s waters stands at 400,000 tonnes per year, confirming that humans are the largest source of this waste. Microplastics have a serious impact on the marine life that ingests them. Early prevention is essential by reducing plastic waste through initiatives such as coastal clean-ups. This aligns with SDG 14 (Life Below Water) to enhance the sustainability of marine and fisheries ecosystems. The activity took place on the Lalowaru coast, South Konawe, with participants from students of SDN 4 Moramo Utara and SMPN 37 Moramo. The stages of the activity included coordination with the schools, preparation of equipment, group allocation, implementation of the activity, and evaluation. It began with an awareness-raising session for the pupils on the importance of protecting marine ecosystems, followed by a beach clean-up to collect inorganic waste using bin bags. The majority of the waste consisted of plastic food packaging. The collected waste was then weighed. Most participants took part in the coastal clean-up with enthusiasm. They demonstrated their understanding by explaining and providing examples of the consequences of damage to these ecosystems. Therefore, sustainable marine education, whether through formal or non-formal channels, is essential as a step towards supporting sustainable marine development.
