“…The research location is a location that is known to have a high enough abrasion effect, according to Putra et al 13 the abrasion process occurred continuously from year to year after the establishment of the estuary as permanent production forest in 2005 and after that there was massive land clearing by the surrounding community. In recent years, the community has begun to experience the impact of changes such as land subsidence, many houses have been submerged by tides and the advancement of the coastline to the mainland.…”

The Mangrove ecosystem of Muara Gembong has been under continuing stress by land occupation, land conversion, and abrasion. This research was aimed to reveal the mangrove and gastropods community structure circumstance. A contribution of the environmental factor was also assessed to evaluate the interaction among them and to track the changes of the ecosystem. This research was conducted by purposive sampling in 3 sampling sites, these were a full reforestation site (A), a central site, that was exist by natural process (B), also a moderate reforestation site (C), with 3 sampling replication each site. About 4 mangrove species within shoreline has been progressively important as a protective flood barrier and abrasion at Muara Gembong. The highest gastropod diversity was found in the B1 site, while the highest dominance was found in A2. The C2 site is the only site that showed us a uniform dispersion of gastropods when the other sites showed a clumped dispersion. It can be implied that the ecosystem has been gradually degraded. Eigen and loading value from Canonical Correspondence Analysis (CCA) revealed that a gastropods community was holistically affected by pH, basal area, canopy, substrate, and TDS. The community of gastropods was influenced 62.14% by pH, and 34.29% by basal area. while the highest dominance was found in A2. The C2 site is the only site that showed us a uniform dispersion of gastropods when the other sites showed a clumped dispersion. It can be implied that the ecosystem has been gradually degraded.

“…Lokasi penelitian merupakan lokasi yang diketahui memiliki pengaruh abrasi yang cukup tinggi, diketahui menurut (Putra, Prasetyo, & Santoso, 2016) proses abrasi terjadi secara berkelanjutan dari tahun ke tahun pasca ditetapkanya muara gembong sebagai hutan produksi tetap pada tahun 2005 dan setelah itu terjadi pembukaan lahan secara besar besaran oleh masyarakat sekitar. Beberapa tahun terakhir, masyarakat mulai mengalami dampak perubahan yang terjadi seperti turunya permukaan tanah, banyak rumah yang terendam pasang surut serta semakin majunya garis pantai ke daratan.…”

Tekanan lingkungan yang disebabkan dari okupasi lahan, alih fungsi lahan, dan tingginya laju abrasi telah dialami oleh Hutan Mangrove Muara Gembong selama bertahun-tahun. Penelitian ini dilakukan untuk mengevaluasi data awal tentang struktur dan komposisi vegetasi mangrove dan gastropoda mangrove serta hubungan keduanya terhadap kondisi lingkungan yang diteliti di garis pantai Desa Pantai Bahagia sebagai landasan evaluasi perubahan yang terjadi pada ekosistem mangrove. Penelitian dilakukan dengan metode purposive sampling. Stasiun penelitian ini dikelompokan menjadi area reforestasi (Stasiun A), area alami tanpa tekanan dan alami dengan tekanan wisata (Stasiun B), serta stasiun reforestasi moderat alami (Stasiun C). Hasil pengamatan di lapangan, terdapat 4 spesies vegetasi mangrove pada area garis pantai penahan abrasi gelombang laut di Pantai Bahagia. Vegetasi tersebut meliputi Avicennia officinalis, Avicennia marina, Rhizopora apiculata, dan Rhizopora mucronata. Hasil pengamatan gastropoda, terdapat 14 spesies gastropoda yang termasuk dalam famili Potamididae, Ellobiidae, Neritidae, Littorinidae, dan Pupinidae. Stasiun dengan diversitas tertinggi ada pada stasiun area alami tanpa tekanan (Substasiun B1), dan indeks dominansi tertinggi ada pada substasiun A2. Distribusi gastropoda menunjukan distribusi mengelompok kecuali substasiun C2 yang merata. Berdasarkan hasil distribusi, lokasi penelitian ini menunjukan lingkungan mengalami degradasi lingkungan. Nilai eigen dan korelasi dari ordinasi CCA menunjukan bahwa pH, kerapatan basal mangrove, tutupan kanopi, jenis sedimen, dan TDS adalah variabel yang secara holistik berkontribusi terhadap komunitas gastropoda secara berurutan. Mayoritas takson gastropoda mengelompok di sisi yang sama dengan pH sebagai variabel dengan nilai korelasi linear terbesar, yaitu 62,14%. Selanjutnya, kerapatan basal mangrove berkontribusi secara positif sebesar 34,29% terhadap komunitas gastropoda.

“…The economic activity requires the logging of mangrove forests so that they can be made for fish ponds, recreational areas, and industrial areas. The impact of this economic activity can be shown from the findings using Landsat satellite imagery from 2012 to 2020, there has been coastal abrasion covering an area of 252,071.71 square meters [11]. Another impact of clearing mangrove forests is the occurrence of tidal floods [12].…”

Coastal management authority that is owned by more than one party will facilitate role conflicts in handling tidal floods. The purpose of this study was to analyze the potential conflict over the role of the local government of Bekasi Regency in dealing with the tidal flood disaster on Muaragembong Beach. The research method uses qualitative descriptive design. Data analysis uses the steps of data collection, data presentation, data condensation, and drawing conclusions. The results of the study show that the handling of tidal floods will not be resolved soon. This is because the Ministry of Forestry and the Environment still insists on having full authority over the land on the coast of Muaragembong, so the District Government does not have a strong aspect of handling it and is supported by the view that tidal flooding is occurring within normal limits. Finally, the regional government of Bekasi Regency has no contingency planning for tidal floods, has not made structural and non-structural mitigation programs, and only wants to provide assistance to disasters that are not related to tidal floods.
