Abstrak. Hutan mangrove di pesisir Kota Langsa semakin lama semakin terancam keberadaannya. Penyalahgunaan hutan mangrove yang dilakukan dalam kurun waktu akhir-akir ini telah menimbulkan berbagai kerusakan sehingga menyebabkan tingkat kekritisannya semakin tinggi. Salah satu upaya yang dapat dilakukan untuk mengatasi hal tersebut adalah dengan memanfaatkan teknologi spasial. Teknologi spasial merupakan salah satu media yang penting untuk melakukan perencanaan pembangunan dan pengelolaan sumber daya alam dengan cakupan yang luas. Penelitian ini bertujuan untuk mengetauhi seberapa besar tingkat kekrtitisan hutan mangrove sehingga dapat dilakukan upaya pemulihan bagi hutan mangrove dengan tingkat kekritisan yang tinggi. Kriteria yang digunakan untuk mengetahui tigkat kekrtitisan hutan mangrove yaitu jenis penggunaan lahan, kerapatan tajuk tanaman, dan ketahanan tanah terhadap abrasi. Hasil penelitian menunjukkan hutan mangrove dengan tingkat kekritisan tertinggi terjadi di kawasan pesisir Langsa bagian timur dengan kategori sangat kritis seluas 453,25 Ha atau 42,16 %, sedangkan hutan mangrove yang termasuk kategori kritis seluas 1.108,99 Ha atau 44%, serta yang tegolong ke dalam kategori tidak kritis seluas 2.337,78 Ha atau 56.70%.Critical Level of Mangrove Forest Using Spatial Technology Case Study in Coastal Areas of LangsaAbstract. Mangrove forests in coastal areas of Langsa are increasingly threatened. The misuse of mangrove forests that have been carried out at the end-time period has caused various damage, causing the critical level to be higher. One effort that can be done to overcome this problem is to utilize spatial technology. Spatial technology is one of the important media for carrying out extensive development planning and natural resource management The purpose of this study is to determine the critical level of mangrove forests so that recovery efforts can be done for mangrove forests with highest criticality level. The criteria used to determine the critical level of mangrove forests are the type of land use, forest canopy density, and soil resistance to abrasion. The results showed that the highest critical level of mangrove forest occurred in the eastern coastal areas of Langsa with very critical category is 453.25 ha or 42.16%, mangrove forests included in the critical category is 1,108.99 ha or 44%, and those classified to the non-critical category is 2,337.78 ha or 56.70%.

Conventional Methods

A large amount of tropical mangrove forest in Indonesia has been lost due to rapid development in coastal areas, such as, aquaculture, industry, housing, and etc. Assessment of mangrove still mostly used conventional methods. It involves labor intensive, time consuming, high costs and impractical for use in large area. To answer these problems, this study aims to study accuracy and effectiveness of forest canopy density (FCD) model of Landsat for monitoring mangrove changes with large area ±2.600 hectares during periods 2002 and 2014 in Central Kalimantan. The result showed that FCD is capable to classified mangrove changes with overall accuracy 89.75%, and known that mangrove changes during approximately 12 years divided into four groups, i.e. deforested areas 11.11%, degraded areas 12.98%, regrowth areas 23.29% and not change areas 52.62%. Concluded that FCD model is quite accurate and effective used to monitor mangrove changes such as deforestation, degradation and regrowth.

Mangrove forests are one of the vital ecosystem components for coastal areas. Therefore, conservation efforts are required for mangrove forests to prevent damage to the broader mangrove forests. The study of local communities through a perception and participation approach was conducted to identify the problem of mangrove forests damage. Aspects of community perception play an essential role in the formulation of mangrove forest management to ensure the sustainability of mangrove forests and maintain community welfare. The survey was conducted from September to December 2017. Respondents in this study are fishers and fish farmers in Muara Pantuan village, Anggana Sub-district, Kutai Kartanegara Regency whom their occupation directly related to the utilization of mangrove forests. Results showed that about 50% of respondents recognized the existence and function of mangrove forests. 15% of respondents did not know about the rules of mangrove forests. Even 30% of them very did not recognize. Regarding law enforcement, 43% of respondents did not know about the law enforcement of mangrove forests although almost 85% of them stated that the regulation of sustainable mangrove forests was required. Furthermore, for the participation of the community, about 57% of respondents were actively involved in the conservation of mangrove forests.Hutan mangrove adalah salah satu komponen ekosistem penting bagi kawasan pesisir. Dalam rangka mencegah kerusakan hutan mangrove yang lebih luas lagi maka perlu upaya pelestarian terhadap hutan mangrove yang masih tersisa melalui pendekatan persepsi dan partisipasi melalui kajian masyarakat lokal. Hal ini penting mengingat aspek persepsi masyarakat memegang peranan penting dalam perumusan pengelolaan hutan mangrove agar sumberdaya tersebut dapat dipertahankan dan ditingkatkan sehingga dapat menjamin keleslarian dan kepentingan sosial ekonomi masyarakat sekitarnya. Tujuan penelitian adalah untuk mengetahui persepsi serta tingkat partisipasi masyarakat dalam pelestarian hutan mangrove di Desa Muara Pantuan Kecamatan Anggana Kabupaten Kutai Kartanegara. Kegiatan penelitian di lapangan dilakukan selama 2 (dua ) bulan dari bulan September 2017 sampai dengan Desember 2017.

Mangrove forests around the world are being impacted by development in adjacent land and water areas. An after-control-impact study was undertaken to assess the effects of mangrove forest pruning on the associated benthic macroinvertebrate fauna. Pruning, undertaken 5 years before our sampling period, reduced the height of the forest canopy from 5 m to 1 m. Macrobenthic assemblages were sampled in September 2000 and January 2001 from two randomly selected sites within the pruned section of forest, and two sites in each of two control locations in the same forest. Assemblage composition in the pruned and undisturbed mangrove forests was not significantly different, nor were there significant differences in variability between the two areas. Similarity matrices for assemblages based on higher taxonomic groups and molluscs were highly correlated with similarity matrices for all taxa, indicating the utility of more rapid forms of assessment in this habitat. The results suggest that although short-term impacts may have occurred, no impact on macroinvertebrate assemblages was evident 5 years after the pruning.

Mangrove, or bakau as it is known in Indonesia, is one of the vegetations commonly found along the shallow coasts, estuaries, deltas and protected coastal areas and are still influenced by rising tides. After the Aceh tsunami disaster, mangrove restoration was intensively conducted in coastal areas all over Indonesia and was made into a special conservation program by the government. Mangrove is distinguishable by its big, wooden stilt roots, sharpening tip in the form of supporting leaves. The roots of the mangrove tree are morphologically distinguishable into heart root which grows into the ground and the stilt root which appear to grabs onto the surface of the ground. Mangrove forests serve several important ecological roles: they act as filters which turns saline water into fresh water, buffer from seawater intrusion, prevent erosion and abrasion, hold sediments to form new habitats, feeding ground, nursery ground, and spawning ground for a number of aquatic wildlife. Mangrove forest also possess economical functions such as as source of income, industrial ingredients for the locals and as source of new mangrove seedlings. Mangunhardjo Village, Urban Community of Mangunhardjo, Mangkang Area, Kecamatan of Tugu, Semarang City, Indonesia was an area dotted with brackish water pond. However, the area had been suffering from the effects of climate change, being inundated by overflow of river and seawater intrusion (rob). These disasters caused decline in the productivity of the ponds in the area. In an effort to combat the adverse effect of environmental change in the area, the locals of Mangunhardjo village decided to shift their livelihood by restoring the surrounding mangrove forest. Mangrove conservation at Mangunhardjo Village was conducted through activities of the program such as mangrove planting, mangrove-based food production, and mangrove waste management by applications of bioactivator bacteria for mangrove composting and production of mangrove-based natural dye for batik fabric. Mangrove-based natural dye for batik fabric from Rhizopora mucronata mangrove waste is a quite promising product and increases people’s income.

The mangrove forest ecosystem protects the land area from the tidal wave hence preventing the coastal areas and properties from severe damage. Mangroves provide valuable ecological services and goods, sediment retention, food sources of some animals, and stabilisation of the coastal areas. Unfortunately, the species have been experiencing an extensive loss in many parts of the world. This paper aims to detect the changes in mangrove forests and possible changes in the Selangor river basin area. The methodology uses remote sensing data via supervised classification on a maximum likelihood algorithm to analyse the distribution of mangrove forests at the Selangor River basin for a thirty-two-year period, from 1989 to 2021. The findings indicate that the percentage of mangroves in the study area has reduced over the study period. The coverage of mangroves has reduced from 24.29 percent (1989) to 15.57 percent in 2008, and continued to reduce to 13.12 percent in 2021. The research finding indicates a decrease in mangroves due to aquaculture, tourism, agriculture, and other human activities. Such a trend may risk coastal and river erosion, thus necessitating a revision of the management policies for environmental protection.

Coastal areas can either meet the human needs or give great contribution to the development. However, rapid infrastrural development in Sorong, west Papua, has been followed by high demand for mangrove timber and caused mangrove forest degradation due to exploitation. This exploitation could also result from high economic value of the mangrove timber. This study was done to analyze the economic value of mangrove wood utilized by the people to support the development process in Sorong. This study used primary data obtained through interviews and the economic value calculation of mangrove forests. It found that Sorong had mangrove economic value of IDR 165,197,833, 491. Wilayah pesisir selain dapat memenuhi kebutuhan hidup manusia juga memberikan kontribusi yang besar bagi pembangunan. Cepatnya pembangunan infrastruktur di Kota Sorong diikuti pula dengan tingginya permintaan akan kayu mangrove dan menyebabkan terjadinya degradasi hutan mangrove akibat eksploitasi. Eksploitasi ini disebabkan juga akibat kayu mangrove memiliki nilai ekonomi. Penelitian yang dilakukan ini bertujuan untuk menganalisis nilai ekonomi kayu mangrove yang dimanfaatkan oleh masyarakat Kota Sorong dalam proses menunjang pembangunan. Penelitian ini menggunakkan data primer yang diperoleh melalui hasil wawancara dan perhitungan nilai ekonomi hutan mangrove. Hasil penelitian ini menunjukkan nilai ekonomi ekosistem hutan mangrove yang berada di Kota Sorong adalah Rp165.197.833.491.

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.
