Abstract
Abstract. Mangrove forest is a coastal forest that is included in one of the important ecosystems found on the coast and small islands. Healthy mangrove forests can function as well as being a care area for various biota, also play an important role in maintaining carbon uptake. The functions and benefits of this forest are very diverse, and it has long been a location for human livelihoods, especially fishermen. But unfortunately the area of this forest is decreasing from year to year due to the clearing of mangrove land into residential and industrial areas including illegal logging, so conservation efforts are needed. Mangrove forests in Wakatobi Regency are a very important resource for coastal areas and small islands, which must be maintained and continuously developed, together with other resources. Efforts to preserve mangrove forests have become the main concern of the parties. However, rehabilitation efforts are still a problem due to very slow growth and even death. The purpose of this research is to design a prototype or simple technology design for trapping organic matter/sediments with nutrients that are also useful for reducing the influence of currents and waves during the propagule planting activity stage and when the mangrove seedlings have started to grow and survive at around 1.5 to 3 years of age. This research is included in the quantitative-applied research where the end result is to produce a small-scale construction product or simple technology and then immediately apply it to the location, namely Melaione-Matahora Beach and Liya Togo Beach. The results obtained are the design (prototype) of this small-scale mangrove trap with a size of 1 m x 1 m x 50 cm, which is shaped like a puzzle box, where each side is interlocked. In the mangrove trap box filled with a mixture of mangrove leaf litter, seagrass litter and humus soil aggregate and sandy soil, then plant propagule on top. During the study lasting up to 5 (five) months, the propagules had grown well, were fertile and survived due to their limiting factors. This research is still a first model of initial stage, and will then be continued by including the reliability test of the structure which will be carried out during the east wind season, namely from June to August as well as the resistance of the sediment deposition in the trap^s
