Abstract

The Baturapa Village community uses mangroves to fulfill their various needs (fuel wood, house construction materials, color dyes and synthetic flower-making raw materials). This utilization must be carried out in a controlled manner to preserve the sustainability of the mangrove ecosystem. This study aims to determine the extent and the current structure of the mangrove community in Baturapa Village. The research was conducted in the mangrove area of Baturapa Village, Lolak District, Bolaang Mongondow Regency, North Sulawesi Province in March 2019.The method used was the line transect method to see the mangrove community structure including density, frequency, species dominance and Important Value Index (INP) and diversity index (H’). Mangrove area was calculated using Google earth pro and ArcGis 10.4 software. The outcomes of the calculation of the area of mangrove in the village of Baturapa are 37.4 hectares. The results of the identification of mangroves in the coastal area of Baturapa Village, Lolak District, Bolaang Mongondow Regency, have 11 species, with 111 total individuals. Of the 3 line transects, the highest species density is Rhizophora stylosa, 800 trees / ha (line transect III) with relative density ( KR) 57.1%, while T\the highest frequency of species is Rhizophora stylosa with a value of 1.0 with a relative frequency (FR) of 50% (line transect III). The highest species dominance is Rhizophora mucronata with a value of 4.6 where relative dominance (DR) is 53.4% (line transect II). Furthermore, the highest species value index (INP) is Rhizophora stylosa with a value of 118.6 (line transect III). Line transect I has the highest diversity index (H;) with a value of 1.99. A value of 1.99 (H’) greater than 1 and smaller 3.3 means that productivity is sufficient, ecosystem conditions are quite balanced and ecological pressure is moderate.Keywords: Baturapa Village, mangrove area, density, frequency, dominance, index important value, mangrove diversity indexABSTRAKMasyarakat Desa Baturapa memanfaatan mangrove untuk memenuhi berbagai kebutuhan hidupnya (kayu bakar, bahan pembangunan rumah,pewarna jarin dan bahan baku pembuatan bunga sintetis).

Abstract

In fact the use or the use of resources and territory or coastal area showed a significant rate. Yet on the other hand the availability of space and resources are in a dilemma because the rate is followed by the use of more that do not consider the sustainability of the resource. It is crucial to increase with increasing population. One of the consequences or impact most noticeably is the damage to the environment, both natural environment in general and specifically the environment of coastal areas. From various studies and concern, for while the environmental damage that occurs in the context of use (exploitation) of natural resources because of: 1) Lack of or perhaps the lack of an integrated approach to the planning and management of resources that are in the coastal region; 2) Lack of adequate information and data to be used as a reference in the management; 3) Lack of community involvement in the management of local government may hoarse coastal power. Management of small -scale coastal resources is an activity in the village / urban neighborhoods implemented as an effort of institutional capacity building and community, improving the quality of the environment, as well as socio-economic improvement of the quality of society by using technology appropriate management of coastal areas for the community. These activities are grouped into 3 categories: 1. Capacity building society in the management of coastal and marine resources through training and mentoring, 2. Environmental improvement activities that influence the activities in improving welfare, 3. The development of alternative employment Keywords : Coastal resources , utilization strategy and management activities ABSTRAK Pada kenyataannya pemanfaatan atau penggunaan sumberdaya dan wilayah atau ruang pesisir menunjukkan laju yang signifikan. Padahal di sisi lain ketersediaan ruang dan sumber daya tersebut berada dalam laju yang dilematis karena diikuti toleh pemanfaatan lebih yang tidak mempertimbangkan keberlanjutan dan kelestarian sumber tersebut. Hal ini bertambah krusial dengan bertambahnya jumlah penduduk. Salah satu akibat atau dampak yang paling terasa adalah kerusakan lingkungan, baik lingkungan alam secara umum maupun lingkungan wilayah pesisir secara khusus. Dari berbagai kajian dan kepedulian, untuk sementara kerusakan lingkungan yang terjadi dalam konteks pemanfaatan (eksploitasi) sumber daya alam oleh karena : 1)Kurangnya atau mungkin tidak adanya suatu pendekatan yang terpadu dalam perencanaan dan pengelolaan sumber daya yang berada dalam kawasan pesisir; 2)Kurangnya informasi dan data yang layak untuk dijadikan acuan dalam pengelolaan; 3)Kurangnya keterlibatan masyarakat dan mungkin pemerintah daerah dalam pengelolaan sember daya pesisir. Untuk berbagai alasan dan pertimbangan tersebut di atas, maka perlu diterapkan strategi pemanfaatan dalam batas-batas ramah lingkungan, melindungi dan mengkonservasi wilayah tertentu, merehabilitasi wilayah yang rusak, serta  meningkatkan kesadaran masyarakat pesisir untuk melestarikan ekosistem pesisir,  yang terintegrasi dalam strategi pengelolaan wilayah pesisir terpadu. Pengelolaan sumberdaya wilayah pesisir skala kecil adalah suatu kegiatan pada tingkat desa/kelurahan yang dilaksanakan sebagai upaya dari kegiatan peningkatan kapasitas kelembagaan dan masyarakat, peningkatan kualitas lingkungan, serta peningkatan kualitas sosial ekonomi masyarakat dengan menggunakan teknologi pengelolaan wilayah pesisir tepat guna bagi masyarakat.  Kegiatan ini dikelompokkan menjadi 3 kategori yaitu: 1.Kegiatan peningkatan kapasitas masyarakat dalam pengelolaan sumberdaya pesisir dan laut melalui pelatihan dan pendampingan, 2.Kegiatan perbaikan lingkungan yang mempengaruhi kegiatan dalam peningkatan kesejahteraan, 3.Kegiatan pengembangan mata pencaharian alternatif.   Kata kunci : Sumberdaya pesisir, strategi pemanfaatan dan kegiatan pengelolaan 1Staf pengajar Fakultas Perikanan dan Ilmu Kelautan Universitas Sam Ratulangi
