“…R. apiculata is a fast-growing wood (fastgrowing mangroves) and has a high adaptation pattern to environmental factors, namely substrate type, salinity fluctuations, tides, organic matter content, temperature, and pH so that the species can grow in almost all mangrove forest zones, from the coastal zone to the riverbank [5]. This is in line with the statement of [6] that the Rhizophora species can adapt and the survival rate to environmental conditions is very high so this species is easy to live in every area. The taproot system makes this species capable of depositing mud on the overgrown substrate, causing the area overgrown with this species to become softer and muddy.…”

A high decrease in Indonesia’s mangrove forests requires effective and efficient rehabilitation efforts. One of the efforts is the use of Rhizophora apiculata as the adaptive mangrove species and the cut-propagule seedling method of the species for accelerating plant propagation. The objectives of this study were to investigate the scientific literature on the use of R. apiculata for mangrove rehabilitation and to analyze the growth of R. apiculata derived from the cut-propagule seedlings. Scientific literature was collected from 2012 to 2022 in Google Scholar. An experimental study was conducted using the following treatments: cut-propagule, growth regulator, and planting media with 3 replications. About 90% of 980 articles stated the R. apiculata as the main species for mangrove rehabilitation. However, there was no study on the effect of cut-propagule seedlings on the growth of R. apiculata. Propagule cutting significantly affects the increase in height and diameter. Treatment of no propagule cutting, growth regulator (10 000 ppm), also a combination of mud+sand resulted in the highest height increment. Treatment of no propagule cutting, no growth regulator, and the combination of mud+sand resulted in the highest diameter increment. The cut-propagule method can be an alternative method to produce more seedlings than no propagule cutting.

“…Sistem perakaran vegetasi mangrove mampu menahan erosi akibat gelombang air laut (Japa & Santoso, 2019). Selain itu, vegetasi mangrove juga membentuk habitat perlindungan bagi hewan-hewan muda dan juga sebagai substrat organisme epifit (Sani, et al, 2019). Mangrove juga memiliki nilai moneter dan non moneter seperti industri kehutanan, industri perikanan, konservasi satwa liar, pariwisata dan perlindungan lingkungan (Chandra, et al, 2011).…”

“…Pada periode tahun 2006-2015 di Nusa Tenggara Barat telah terjadi penurunan luas area hutan mangrove sebesar 33.50 % dari luas total sekitar 18.256,88 ha pada tahun 2006 (Farista dan Virgota, 2021). Pada tahun 2007 dilaporkan bahwa kawasan hutan mangrove di Pulau Lombok yang masih dalam kondisi baik sekitar 1.643 ha (49.7%) (Sani et al, 2019). Hal ini menunjukkan bahwa di NTB, khususnya P. Lombok, terjadi ancaman kerusakan ekosistem mangrove yang cukup besar.…”

The area at the research site has a mangrove community that is experiencing disturbances due to the conversion of land into ponds. Therefore, the purpose of this study was to assess the actual condition of mangrove vegetation after land conversion. The method used in this research is a survey and the sampling point is determined randomly (random sampling). Furthermore, observations were made on two existing mangrove blocks, namely the Natural Block and the Rehabilitation Block. Observation plots were placed randomly in the Natural Bok and Rehabilitation Block. Randomization was carried out on the regional map by making a grid measuring 10x10m and numbered. The data were analyzed using the analysis of the diversity index value (Shannon-Wiener), the evenness index (Evenness), the proportion of vegetation at each growth level and the pattern of vegetation distribution (Morisita Index). The results showed that the value of species diversity in the Natural Block was 0.95 and the Rehabilitation Block was 0.99. This value is included in the category of low diversity. The evenness index obtained a value of 0.49 in the Natural Block and 0.45 in the Rehabilitation Block. This value indicates that the distribution of the number of individuals in each species is not evenly distributed. Vegetation is dominated by Trees (in the Natural Block) and Saplings (in the Rehabilitation block). The vegetation in the Natural Block is older than the Rehabilitation Block. Meanwhile, based on the value of the Morisita index, the distribution pattern of mangrove vegetation in the study area is included in the cluster category.

“…Indonesia merupakan negara tropis yang paling banyak ditumbuhi hutan mangrove dengan luasan sekitar 4,25 juta Ha. Akan tetapi, laju kerusakan hutan mangrove di Indonesia juga sangat tinggi sehingga diperkirakan luas ekosistem mangrove telah berkurang 2,15 juta Ha dari total sebelumnya (Sani et al, 2019). Kerusakan mangrove merupakan masalah serius yang terjadi di Indonesia, termasuk mangrove di Kecamatan Brondong, Lamongan, Jawa Timur.…”

Hutan mangrove merupakan kumpulan vegetasi mangrove yang tumbuh pada wilayah intertidal dan mempunyai banyak fungsi. Seiring dengan meningkatnya populasi manusia, kerusakan mangrove juga banyak terjadi, salah satunya di Kecamatan Brondong, Kabupaten Lamongan. Salah satu upaya konservatif untuk mengembalikan fungsi hutan mangrove adalah dengan rehabilitasi mangrove. Keterbatasan informasi jenis mangrove yang cocok untuk rehabilitasi dan luasan mangrove, serta sulitnya akses ke hutan mangrove menjadi alasan dilakukannya penelitian ini. Tujuan penelitian ini adalah untuk mengetahui jenis mangrove dan mengetahui luasan mangrove yang dapat ditanami di Kecamatan Brondong dengan menggunakan metode penginderaan jauh. Metode penginderaan jauh digunakan untuk proses digitasi tipe sedimen dan mangrove existing. Analisis harmonik digunakan untuk menentukan nilai pasang surut. Sedangkan, penentuan daerah genangan menggunakan metode Sistem Informasi Geografis (GIS). Hasil analisis menunjukkan bahwa di Kecamatan Brondong terdapat mangrove existing dengan tipe sedimen berpasir, berlumpur dan berbatu. Analisis pasang surut menghasilkan rata-rata pasang 0,57±0,19 dan surut -0,53±0,21. Jenis mangrove yang dapat ditanam meliputi jenis Rhizophora sp., Avicennia sp, Sonneratia sp, Bruguiera sp., Aegiceras sp., Ceriops sp., dan Xyocarpus sp. Luas wilayah yang tidak dapat ditanami mangrove memiliki total sebesar 330,093 Ha. Sedangkan total luasan dari mangrove yang dapat ditanami adalah sekitar 872,483 Ha, sehingga total keseluruhan dari luasan mangrove pada wilayah tersebut adalah sebesar 1.202,577 Ha. Hasil penelitian ini diharapkan dapat menjadi salah satu referensi dan pertimbangan dalam rehabilitasi hutan mangrove di Kecamatan Brondong maupun di wilayah lainnya. Mangrove forest is a collection of mangrove vegetation that grows in intertidal areas and has many functions. Along with the increase in human population, there is also a lot of damage to mangroves, one of which is in Brondong District, Lamongan Regency. One of the conservative efforts to restore the function of mangrove forests is mangrove rehabilitation. The limited information on the types of mangroves suitable for rehabilitation and the extent of mangroves, as well as the difficulty of accessing mangrove forests are the reasons for conducting this research. The purpose of this study was to determine the types of mangroves and to determine the extent of mangroves that can be planted in Brondong District by using remote sensing methods. Remote sensing method is used for digitizing the existing sediment and mangrove types. Harmonic analysis is used to determine tidal values. Meanwhile, the determination of the inundation area uses the Geographic Information System (GIS) method. The results of the analysis show that in Brondong District there are existing mangroves with sandy, muddy and rocky sediment types. Tidal analysis resulted in an average tide of 0.57±0.19 and a low tide of -0.53±0.21. The types of mangroves that can be planted include Rhizophora sp., Avicennia sp, Sonneratia sp, Bruguiera sp., Aegiceras sp., Ceriops sp., and Xyocarpus sp. The total area that cannot be planted with mangroves is 330,093 Ha. While the total area of mangrove that can be planted is around 872.483 Ha, so that the total area of mangrove in the area is 1,202.577 Ha. The results of this study are expected to be one of the references and considerations in the rehabilitation of mangrove forests in Brondong District and in other areas.
