Indonesia has 3.4 million hectares or 24% of the world's 13.8 million hectares of mangrove forests. In its development, Indonesia's mangrove area continues to decline and it is recorded that an area of ​​637,624 hectares (18.95%) is in critical condition due to canopy cover which is less than 60%. Mangrove forests can absorb large waves including tsunamis, prevent abrasion, absorb carbon dioxide 5 times greater than tropical forests in the highlands, and are a habitat for several types of wildlife. Thus, Indonesia has a very significant role in the existence and sustainability of the world's mangrove forests. Based on 2018 data, DKI Jakarta Province has 300 hectares or about 10.7% of the total mangrove forest in Indonesia which is spread in the Angke Kapuk Nature Park, Muara Angke Wildlife Sanctuary, Angke Kapuk Protection Forest and Kamal Muara Production Forest as well as part of the last remaining mangrove forest in DKI Jakarta province. Based on this phenomenon, efforts are needed to maintain the existence and sustainability of mangrove forests, especially in the city of Jakarta. One of the important actors in this effort is the youth with growing awareness of environmental issues. Teenagers as future milestone holders need to understand the importance of the existence and sustainability of mangrove forests. The problem faced is the need for an educational activity that is by the characteristics of adolescents. Therefore, the implementing team initiated education on the existence and sustainability of the mangrove forest ecosystem for youth (12-24 years old) in Tanjung Gedong Village who are members of the At-Taufiq Tanjung Gedong Mosque Youth with an Experiential Learning Discovery Journey approach which was carried out in 3 (three) stages, namely the introduction stage by providing infographics and videographics materials, the observation stage with a visit to the Mangrove Nature Tourism Park, Angke Kapuk, North Jakarta; and the reflection stage through reflection instruments filled out by partners. Based on the results of the activity, it is known that all respondents have theoretical experience about the existence and sustainability of mangrove forests obtained from the school. Community service activities (PkM) provide new experiences in the creative process to understand the topic of PkM, namely the existence and sustainability of mangrove forest ecosystems in Jakarta.   Abstrak Indonesia memiliki 3,4 juta hektar atau 24% dari total 13,8 juta hektar hutan mangrove dunia. Dalam perkembangannya, luas mangrove Indonesia terus mengalami penurunan dan tercatat seluas 637.624 hektar (18,95%) dalam kondisi kritis karena penutupan tajuk yang kurang dari 60%. Hutan mangrove bermanfaat untuk meredam gelombang besar termasuk tsunami, mencegah abrasi, menyerap karbondioksida 5 kali lebih besar daripada hutan tropis di dataran tinggi, dan sebagai habitat bagi beberapa jenis satwa liar. Dengan demikian, Indonesia memiliki peranan yang sangat signifikan bagi eksistensi dan keberlanjutan hutan mangrove dunia. Berdasarkan data tahun 2018, Propinsi DKI Jakarta memiliki 300 hektar atau sekitar 10,7% dari total hutan mangrove di Indonesia yang tersebar di Taman Wisata Alam Angke Kapuk, Suaka Margasatwa Muara Angke, Hutan Lindung Angke Kapuk dan Hutan Produksi Kamal Muara sekaligus merupakan bagian dari hutan mangrove terakhir yang tersisa di provinsi DKI Jakarta. Berdasarkan fenomena tersebut, maka diperlukan upaya untuk menjaga eksistensi dan keberlanjutan hutan mangrove khususnya di Kota Jakarta. Salah satu aktor penting dalam upaya tersebut adalah kalangan remaja dengan tumbuhnya kesadaran akan isu lingkungan. Remaja sebagai pemegang tonggak masa depan perlu memahami pentingnya eksistensi dan keberlanjutan hutan mangrove. Permasalahan yang dihadapi adalah perlunya sebuah kegiatan edukasi yang sesuai dengan karakteristik bagi remaja. Oleh karena itu, tim pelaksana   menginisiasi edukasi eksistensi dan keberlanjutan ekosistem hutan mangrove bagi remaja (berusia 12 – 24 tahun) di Kampung Tanjung Gedong yang tergabung dalam Remaja Masjid At-Taufiq Tanjung Gedong dengan pendekatan Experiential Learning Discovery Journey yang dilaksanakan dalam 3 (tiga) tahap, yaitu tahap pengenalan dengan memberikan materi infografis dan videografis, tahap observasi dengan kunjungan ke Taman Wisata Alam Mangrove, Angke Kapuk, Jakarta Utara; dan tahap refleksi melalui instrumen refleksi yang diisi oleh mitra. Berdasarkan hasil kegiatan, diketahui seluruh responden telah memiliki pengalaman teoretis tentang eksistensi dan keberlanjutan hutan mangrove yang diperoleh dari bangku sekolah. Kegiatan pengabdian kepada masyarakat (PkM) memberikan pengalaman baru dalam proses kreatif untuk memahami topik PkM yaitu eksistensi dan keberlanjutan ekosistem hutan mangrove di Jakarta.

Mangrove forests have important ecological functions as a controller of environmental quality in coastal areas and absorber of atmospheric carbon. The mangrove ecosystem has a unique vegetation structure which form vegetation zonation that consists of different forest stands characteristics and tree species. This study aims to analyze the relationship between vegetation structural properties and the estimated aboveground carbon (AGC) stock of mangrove forest in Bedul mangrove, Banyuwangi, East Java, Indonesia. The study was conducted by field observation at some purposively selected sample locations. Field measurement was aimed to collect data about mangrove tree diameter at breast height (DBH), species, tree height, and fractional canopy cover. Mangrove biomass was indirectly calculated by allometric method based on mangrove species to estimate AGC in mangrove stands. The highest total AGC found in this study was 114.09 tons/ha at Rhizophora mucronata dominated forest, while the lowest total AGC was 12.86 tons/ha with Ceriops tagal as the dominant species. The AGC estimation in mangrove stands correlated positively with DBH and tree height. However, the biomass content and AGC are affected by the number of mangrove stands. The difference in the number of stands affect the amount of carbon content at each sample point.

Indonesia has a lot of potential for nature tourism in the form of mountains, sea, and beaches. This is also an attraction for tourists to make Indonesia as the preferred natural tourist destination when on vacation. Especially West Java, West Java is one of the provinces that are in great demand by local and outside tourists.Besides being famous for its local culture and its unique culinary variety, West Java is also known for its cool air, especially in some parts that are still preserved in nature, the natural potential that is still good and is maintained as an attraction for West Java to attract tourists. One of the famous areas in the city of Bandung which is a tourist destination is the Lembang Region.From the last five years the lodging area in Lembang has increased, currently in Lembang sub-district itself has 13 lodging units in the form of resorts. The amount itself is influenced by the high demand for lodging accommodation especially when the holiday season arrives. But of that number, resorts that have complete and well-maintained facilities and conditions are still not completely even. Based on this fact, the purpose of designing this resort is expected to be the best tourist area in the region to be able to adjust to the conditions of the land conditions, be able to use and not damage the existing land on the design land.The study used in this design is based on the description that occurs today with the support of the literature that supports the theory and analysis that is done. Implementation analysis was carried out using macro and microanalysis methods. Macro analysis is an analysis on a regional scale. While microanalysis is an analysis of the design site, which includes activity analysis, function analysis, space analysis, site analysis, shape analysis, and display and structural analysis and utility.The concept of site and building in this design will produce a conceptual relationship that will later become a guideline in making a design. This concept includes the proposed concept of site design, form, structure, and utility.

Mangrove forests can ameliorate the impacts of typhoons and storms, but their extent is threatened by coastal development. The northern coast of Vietnam is especially vulnerable as typhoons frequently hit it during the monsoon season. However, temporal change information in mangrove cover distribution in this region is incomplete. Therefore, this study was undertaken to detect change in the spatial distribution of mangroves in Thanh Hoa and Nghe An provinces and identify reasons for the cover change. Landsat satellite images from 1973 to 2020 were analyzed using the NDVI method combined with visual interpretation to detect mangrove area change. Six LULC classes were categorized: mangrove forest, other forests, aquaculture, other land use, mudflat, and water. The mangrove cover in Nghe An province was estimated to be 66.5 ha in 1973 and increased to 323.0 ha in 2020. Mangrove cover in Thanh Hoa province was 366.1 ha in 1973, decreased to 61.7 ha in 1995, and rose to 791.1 ha in 2020. Aquaculture was the main reason for the loss of mangroves in both provinces. Overall, the percentage of mangrove loss from aquaculture was 42.5% for Nghe An province and 60.1% for Thanh Hoa province. Mangrove restoration efforts have contributed significantly to mangrove cover, with more than 1300 ha being planted by 2020. This study reveals that improving mangrove restoration success remains a challenge for these provinces, and further refinement of engineering techniques is needed to improve restoration outcomes.

In this study, we examined the natural recovery of mangroves in abandoned shrimp ponds located in the Wunbaik Mangrove Forest (WMF) in Myanmar using artificial neural network (ANN) classification and a change detection approach with Sentinel-2 satellite images. In 2020, we conducted various experiments related to mangrove classification by tuning input features and hyper-parameters. The selected ANN model was used with a transfer learning approach to predict the mangrove distribution in 2015. Changes were detected using classification results from 2015 and 2020. Naturally recovering mangroves were identified by extracting the change detection results of three abandoned shrimp ponds selected during field investigation. The proposed method yielded an overall accuracy of 95.98%, a kappa coefficient of 0.92, mangrove and non-mangrove precisions of 0.95 and 0.98, respectively, recalls of 0.96, and F1 scores of 0.96 for the 2020 classification. For the 2015 prediction, transfer learning improved model performance, resulting in an overall accuracy of 97.20%, a kappa coefficient of 0.94, mangrove and non-mangrove precisions of 0.98 and 0.96, respectively, recalls of 0.98 and 0.97, and F1 scores of 0.96. The change detection results showed that mangrove forests in the WMF slightly decreased between 2015 and 2020. Naturally recovering mangroves were detected at approximately 50% of each abandoned site within a short abandonment period. This study demonstrates that the ANN method using Sentinel-2 imagery and topographic and canopy height data can produce reliable results for mangrove classification. The natural recovery of mangroves presents a valuable opportunity for mangrove rehabilitation at human-disturbed sites in the WMF.

Leaf litter represents a food source to many organisms that may directly contribute to organic matter decomposition. In addition, the physical presence of these vegetal detritus contributes for the modification of some environmental areas and produce microhabitats that may act as a refuge against predators and desiccation for many animals. The pulmonate gastropod Melampus coffeus (Linnaeus, 1758) (Ellobiidae) is a very common specie in Atlantic Coast mangrove forests and feeds on fallen mangrove leaves. It was hypothesized that the spatial distribution of Melampus coffeus is directly affected by mangrove leaf litter biomass deposition. Thus, this research aimed at evaluating the spatial distribution of these gastropods in relation to the biomass of mangrove leaf litter through a twelve-month period. The study area was established in the middle estuary of Pacoti River, state of Ceará, Brazil where two adjacent zones with different topographic profiles were determined. Samples of Melampus coffeus and leaf litter were collected monthly, throughout a year, from the mangrove ground surface. The results indicated that the presence of twigs in mangrove litter favor the occupation by smaller individuals of M. coffeus, probably because smaller individuals are more susceptible to predator attacks and desiccation than larger ones, and twigs and branches may provide a safe microhabitat.

The area of mangrove forests in Indonesia is currently only spanning as much as 3.4 milion acres, so there is a need for the participation of the government and community to maintain its sustainability. South Halmahera is the district with the largest mangrove area in the North Maluku Province. One of the mangrove areas in the District of South Halmahera is located at Sayoang Village, East Bacan Subdistrict Up until its eleventh founding anniversary, this district have never conducted an inventorizing of its mangroves, both ecological and social studies in the field of public. This study aims to analyze the compotition of mangrove species in Sayoang Village, East Bacan Subdistrict, South Halmahera, and identify the knowledge of surrounding communities of mangrove areas as protected areas. Data were retrieved using sampling method with applications terraced paths, and analyzed by calculating its important value index (INP) and its index value diversity (IVD). The public social data were taken using in-depth interviews and questionnaires. Results obtained from this study show that the mangrove forest in Sayoang Village, East Bacan District, Halmahera, consists of major mangrove species with as many as eleven species belonging to families Rhizophoraceae, Sonneratiaceae, Avicenniaceae, Meliaceae and Myrtaceae, and as many as three species of minor mangrove belonging to families of Loranthaceae, Acanthaceae, and Pteridaceae. The mangrove's species diversity and richness is and low, but it has high evenness. The results showed that 60% of total respondents know the benefit of mangrove as fish habitat, while for mangrove area as conserving areas, 50% of total respondent don't know the status of the area. The cutting problems happened in mangrove areas, 90% of total respondent know the activity and 85% of total respondent think that the logging activities in mangrove area is still allowed. The management activity of mangrove area in Sayoang village hasn't been conducted, either by the community or by local Dinas Kehutanan, and 53% of total respondent still wishing the mangrove can give more benefit economically.Key words: Mangrove forest, mangrove protected areas, community knowledge
