“…(f) Change Detection: Change detection aids in understanding the dynamics of mangrove coverage and distribution. Each data series in this study is assigned an identifier, and mangrove changes are assessed by aggregating all the identifiers obtained [5]. The annual rate of mangrove loss is calculated using Puyravaud's [11] formula, using mangrove coverage data at two time points.…”

“…Among these, Indonesia stands out as it boasts the world's largest mangrove coverage. Between 1996 and 2020 [4], Indonesia experienced a deforestation of mangroves totalling 1,739.04 km², with the Riau Province seeing a significant decline due to factors such as land conversion for agriculture, palm oil plantations, oil and gas exploitation, and urban development [5].…”

This study used remote sensing technology, specifically Landsat 5 TM and Sentinel-2 MSI images, to map mangrove distribution in ’Pro Mangrove’ Villages, Indragiri Hilir District, Riau Province, Indonesia, from 1989 to 2021. The multi-resolution segmentation (MRS) and Random Forest (RF) algorithms were used to identify changes in land cover over this period. The study found a notable increase of 482.62 hectares in mangrove area over the 32-year period, with a recovery clear from 2014, possibly due to rising mangrove conservation awareness. The study also identified possible disturbances such as exploitation before 1989. The Random Forest algorithm proved effective in mapping mangroves and surrounding land cover. The study underscores the utility of remote sensing technology in tracking mangrove dynamics, which is fundamental for informed conservation and sustainable land management strategies. The findings are expected to guide local authorities, conservation entities, and other stakeholders in devising strong mangrove conservation and management strategies to curb deforestation and promote sustainable land use practices in the Riau Province.

Mangroves (Rhizophora apiculata) are one of the plants that grow in mangrove forests. The significant degradation of mangrove forests in Indonesia requires effective and efficient rehabilitation efforts. Efforts to provide superior seeds in a short time and in large quantities, one of which is through tissue culture. ZPT (Growth Regulator) Kinetin and IAA in balance can stimulate the morphogenesis process in the explant. This study used a 4×4 factorial randomized complete (RAL) design with 3 replications. The first factor is the concentration of kinetin. 0 mg/L, 1 mg/L, 3 mg/L, and 5 mg/L. The second factor is IAA concentrations of 0 mg/L, 0.5 mg/L, 1 mg/L, and 1.5 mg/L. The parameters observed were explant growth time, explant growth percentage, and bud height. The results showed an interaction with the plant growth time factor, and the best plant growth rate was achieved using the kinetin treatment of 5 mg/L and the IAA treatment of 1.5 mg/L, while the best shoot height factor was found in the kinetin treatment of 5 mg/L. l and IAA 1 mg/L treatment concentrate.

“…Riau Province has the third largest mangrove ecosystem área in Indonesia, with 213,459.21 hectares [21]. The mangroves of Riau Province are scattered along river mouths and coastlines in seven districts/cities, including the coast of Bengkalis Regency, Meranti Islands, and Siak, which are the best spawning sites for fish.…”

Mangroves are crucial to fisheries as nurseries; they can be used as spawning and feeding grounds for fish, including Longtail Shad fish (Tenualosa macroura). The objective of the study was to analyze the mangrove vegetation used as Longtail Shad fish spawning ground. It was carried out from January to May 2021, using a checkered line method with six sampling stations. Each station was placed in three transects with three plots for each transect. Density, relative density, frequency, relative frequency, dominance, relative dominance, and importance value index were included in the vegetation analysis. There were 13 true mangrove types and 1 mangrove associate type at the study locations. The highest mangrove density was found at Station 3 with 3300.48 Ind/Ha, categorized as good. The highest mangrove coverage was found at Station 2, with an exceptionally dense category (76.34%). The regression analysis revealed a substantial relationship between density and mangrove and the water salinity at a 0.002 significance value (<0.05). Based on the gut content analysis in establishing the fish's eating habits, the type of food consumed by the Longtail Shad fish was mostly mangrove litter, representing 44.66% of the total stomach contents. The result of the study clearly shows that mangroves are crucial for Longtail Shad fish. A good mangrove ecosystem will provide good water quality for the migration process of longtail shad fish and produce mangrove litter as fish food. Mangrove ecosystem management can support the management of Terubuk fisheries.
