Abstract

Mangroves play an important role in carbon storage and absorption. Mangrove ecosystems absorb carbon dioxide from the atmosphere through photosynthesis, converting it into biomass. Mangroves can store up to four times more carbon per unit area than tropical forests. This study aims to determine the density, stem diameter, basal area of ​​mangroves, biomass, content, and the ability of mangroves to absorb carbon in the air. The method used is the calculation of several ecological indices. While the carbon content and absorption use the allometric method to determine the biomass of mangrove species. Furthermore, the calculation of carbon content and carbon absorption capacity. The average density of mangroves obtained ranges from 0.24-0.55 ind / m2, while the average DBH is between 6.86-16.10 cm and the average basal area is 36.94-203.48 m2. The average biomass of mangrove trees is 13,311-98,752 kg / tree or 288,885 ± 96,957 tons / ha. The average carbon content is6,256-46,414 kg/tree or 107,576±45,570 tons/ha. The carbon absorption capacity of the coastal mangrove forests of North Sinjai is an average of 22,961-170,338 kg/tree or 394,803±167,241 tons/ha. Mangroves are one of the key components in climate change mitigation. Conservation and restoration of mangrove ecosystems are important strategies in efforts to mitigate global climate change and improve the sustainability of coastal environmental ecosystems.

Abstract

Mangrove forests are one of the coastal ecosystems of tropical waters that have various potential benefits for both the environment and humans. The existence of mangrove forests is very necessary for the future of the earth. Mangrove forests have one very important function, namely as an absorber and store of carbon (C). Mangrove forests can store more than three times the average carbon storage per hectare by tropical land forests. This study aims to determine the carbon content and carbon absorption in leaves, roots and soil on the mangrove coast, especially in North Sinjai, Sinjai Regency. The method used in this study is the sampling method to measure the carbon content in leaves, roots and soil. The analysis will involve direct measurements in the field and laboratory analysis to obtain accurate data. The carbon content in mangrove leaves ranges from 0.9-0.11 tons/ha, with a carbon absorption capacity of 0.33-0.42 tons/ha. In the roots, the carbon content ranges from 0.44-0.72 tons/ha with an absorption capacity of 1.60-2.64 tons/ha. The carbon content in the soil ranges from 8.66-156.83 tons/ha with an absorption capacity of 31.79-575.55 tons/ha. This study can be used as basic data in future policies for climate change mitigation, especially the mangrove ecosystem in Sinjai Regency, South Sulawesi Province and can open up opportunities for carbon-based economic schemes such as carbon trading.

Abstract

Petani kentang di Desa Kanreapia menghadapi tantangan fluktuasi harga, ketergantungan pada tengkulak, kelembagaan tani lemah, dan minimnya pengolahan pascapanen, dengan produktivitas 20 ton/ha (dibawah potensi 30 ton/ha). Penelitian ini bertujuan mengidentifikasi masalah aktual, merumuskan strategi partisipatif, dan memperkuat kelembagaan serta pemasaran berbasis kearifan lokal. Menggunakan participatory action research (PAR) melalui diskusi terstruktur dan observasi lapangan bersama 25 petani, penyuluh, dan akademisi. Hasil mengungkap empat masalah utama: (1) ketergantungan pada tengkulak, (2) minim diversifikasi produk olahan, (3) kelembagaan tidak optimal, dan (4) akses informasi terbatas. Rekomendasi mencakup penguatan kelembagaan sebagai unit bisnis kolektif, pelatihan pascapanen, dan kolaborasi pemasaran digital. Pendekatan partisipatif efektif membangun solusi kontekstual, namun memerlukan pendampingan jangka panjang dan integrasi kebijakan lokal untuk keberlanjutan.

Abstract

One of the determining variables that influences coral growth morphology is the aquatic environment. Reef corals are unusual organisms with plant-like development patterns. Reef growth is influenced greatly by the aquatic environment, particularly hydro-oceanography. The same type of coral can have different morphological forms. This mismatch in form can lead to type identification mistakes. There is still a lack of research on morphological changes as an impact of coral plasticity in responding to environmental variables. The goal of this work is to compile a bibliography of coral morphological plasticity studies. Publish or Perish (PoP) program locates the Scopus database and processes the articles. After screening, 101 of the 138 articles found in the Scopus database are eligible to be found. Mendeley reference manager software is then used to handle the selected references. After maintaining the database, use VOSviewer software to classify and visualize the data. The findings suggest that the research topic was chosen based on keywords. Coral morphological plasticity research is primarily focused on the terms coral colonies and species. Small-scale coral morphology, morphological variability, and coral morphometrics are among the topics that have received little attention. The possibility of conducting research on the three subjects is still open. There are still many unanswered mysteries about coral. This work is crucial to research since it illustrates the direction of future plans for exposed coral morphology and plasticity. This review serves as a useful starting point for future coral morphology and plasticity research.
