Penelitian ini bertujuan untuk mengkaji tingkat kerusakan dan faktor penyebab kerusakan ekosistem mangrove di Desa Keera Kecamatan Keera Kabupaten Wajo serta merumuskan strategi rehabilitasi dalam pengelolaan ekosistem mangrove yang belum tepat. Hasil penelitian menunjukkan bahwa kondisi penutupan mangrovr di wilayah pesisir Desa Keera dalam kategori baik (rata-rata persentase dari jenis penutupan tertinggi Rhizopora apiculata 62,5%). Hasil interpretasi citra juga menunjukkan adanya pengurangan luasan hutan mangrove sebesar ±28,15 Ha dari tahun 2013-2017. Kerusakan ekosistem mangrovedisebabkan oleh konversi lahan mangrove untuk dijadikan lahan tambak dan abrasi akibat kurangnya pemahaman masyarakat terhadap pentingnya pelestarian ekosistem mangrove. Arahan strategi rehabilitasi hutan mangrove di Desa Keera berdasarkan hasil analisis SWOT ditetapkan 8 strategi yaitu: 1) Mengembalikan fungsi mangrove sesuai dengan pola ruang ekologi rehabilitasi; 2) pengadaan sarana budidaya mangrove (pembibitan dan penyemaian) yang dikelola langsung oleh masyarakat; 3) peningkatan kualitas SDM masyarakat sekitar ekosistem mangrove; 4) Meningkatkan tugas pokok kelompok masyarakat pengawas melalui bantuan operasional; 5) penegakan hukum dan penguatan kelembagaan; 6) Penanaman kembali kawasan pesisir mangrove yang terindentifikasi rusak berat karena abrasi; 7) peningkatan partisipasi masyarakat dan stakeholder lainnya dalam kegiatan rehabilitasi ekosistem mangrove; 8) pengembangan sistem tambak berbasis (silvofishery) yang baik.

Sea Bamboo (Isis hippuris) is a fish species that is protected based on a certain period of time (moratorium). This research was conducted from September to October 2018. This research was conducted with the aim of Knowing the abundance criteria of sea bamboo (Isis hippuris) in the waters of Konawe, The results of this study indicate that: (1). The highest abundance of sea bamboo  located in Toronipa Village with overflow categories. Followed by Bokori Island with a lot categories, Wawohara Village medium category, Saponda Laut Island rare category is rare, and Saponda Island Land rare category.

Potensi sumberdaya wilayah dan laut Kabupaten Pangkep cukup melimpah, diantaranya ikan-ikan yang melakukan ruaya ke pantai saat pasang air laut. Penelitian dilaksanakan  di perairan Kabupaten Pangkep. Data  dikumpulkan terdiri dari data primer dan sekunder, menggunakan metode observasi  langsung di lapangan. Pengukuran pasang surut dilakukan setiap fase bulan selama 24 jam.  untuk 4 fase bulan. Produksi hasil tangkapan dikumpulkan berdasarkan fase bulan, dengan nilai hasil tangkapan yang didasarkan pada harga local  setiap setiap fase bulan. Analisis pasang surut menggunakan  metode adriminalty dan  analisis kuantitatif terhadap nilai produksi ikan hasil tangkapan trap net (Rp). Hasil analisis yang dilakukan, ditetapkan nilai pasang surut, pada fase bulan mati mengalami pasang tertinggi 162 cm dan surut terendah 59 cm, nilai mean sea level 110,5 cm.  Fase bulan seperempat awal pasang tinggi 115 cm dan surut terendah 23 cm nilai mean sea level 69 cm.  Fase bulan purnama pasang tertinggi 185 cm surut terendah 42 cm, nilai mean sea level 113,5 cm dan fase bulan seperempat akhir pasang tertinggi 149 cm dan surut terendah 40 cm nilai mean sea level 94,5 cm.  Nilai produksi dari hasil alat tangkap trap net terrtinggi fase bulan purnama, disusul fase bulan mati, fase bulan seperempat akhir dan fase bulan seperempat awal.

The purpose of this research was technology-enhanced research in higher education. Design-based research for creating courses using the management system in the E-Learning 5.0 has proven its promise as a tool useful for both research and design of technology-enhanced learning environments over the last decade (TELEs). In this article, we characterize and explain design-based research characteristics, outline the relevance of design-based research in the creation of TELEs, suggest principles for applying design-based research with TELEs, and address potential challenges in using this approach. This inaugural special issue of Studies in Technology Enhanced Learning focuses on ‘theory,’ a controversial subject. While theory has been criticized for being vague or alienating at times, it is safe to conclude that theory has never been as profoundly rooted in Technology Enhanced Learning (TEL) science as it has in many other fields of scholarship.

The purpose of this study was to determine the density level of the mangrove ecosystem and to determine the absorption capacity of CO2 gas per hectare on the basic mangrove substrate found in the Lantebung Ecotourism Area, Makassar City. This research was conducted in July-December 2021 in the Lantebung Ecotourism Area, Makassar City. This study uses the Field Observation method to observe, measure and collect data, including primary and secondary data. Analysis of mangrove ecosystem density data and analysis of carbon uptake of mangrove substrates using the help of statistical data processing programs. Based on the results of the study, it shows that density can affect the amount of biomass, carbon stock content and CO2 absorption which has a strong relationship. The density of mangroves in plots I, II, and III (land-sea) has a higher density; The higher the density, the greater the total carbon stock and the ability to absorb CO2 gas per hectare in a mangrove ecosystem; Carbon content, carbon stock, and CO2 absorption capacity in mangrove ecosystems are higher at the surface than at depth but fluctuate up and down at each depth level.
