Mangrove ecosystems in coastal areas play an important role in supporting physical, biological, and environmental economic functions. One of the alternatives to preserve the mangrove ecosystem is integrated area management. Bulaksetra Beach is a mangrove area located on the East Coast of Pangandaran which has the potential to be developed as an ecotourism area. The Edu-ecotourism area which combines conservation, education, research, and economy requires good and appropriate management. Analysis of land suitability, vegetation types and environmental conditions is important in making decisions and determining the feasibility of an area. Facilities and infrastructure are one of the elements and indicators that support the success of an Edu-ecotourism area. Observations on water conditions, types of mangrove vegetation, water substrate, weather and topography were carried out to determine the feasibility of developing facilities and infrastructure in the Bulaksetra area. The results showed that the Bulaksetra area was feasible to be developed into an Edu-ecotourism area with an average salinity measurement of 14 ppt, an average rainfall of 46.4 mm - 81.3 mm, a sandy mud substrate and a gentle topography. The zoning of the mangrove ecosystem was carried out based on the main mangrove vegetation in Bulaksetra, namely Avicennia alba and Rhizophora apiculata. The selection of vegetation in the landscape design is adjusted to the natural vegetation and topography in the Bulaksetra area. The supporting facilities for Bulaksetra Edu-ecotourism were designed include mangrove trekking, canoeing docks and mangrove galleries. Facilities are designed according to area size, landscape, and suitability of location. Further studies such as the selection of design and building materials, material costs, construction costs, operational costs and maintenance costs need to be carried out to determine the appropriate building construction. The development of Bulaksetra Edu-ecotourism facilities and infrastructure is expected to contribute to the development of the mangrove ecosystem so that it becomes a center for information, education, and conservation for the public, especially in Pangandaran Regency.

Abstract. Isroni W, Islamy RA, Musa M, Wijanarko P. 2019. Short Communication: Species composition and density of mangrove forest in Kedawang Village, Pasuruan, East Java. Biodiversitas 20: 1688-1692. Mangrove is one of ecosystems located in estuary and shallow coastal waters and its existence has a significant role for life. The aim of this study was to identify species composition and density of mangrove forest in Kedawang village, Nguling Sub-district, Pasuruan District, East Java, Indonesia. Survey method using belt transects was carried at three sampling points. Results of this study showed that mangrove vegetation in Kedawang includes five species from three families, namely Avicenniaceae (Avicennia alba and Avicennia marina), Rhizophoraceae (Rhizophora apiculata and Rhizophora mucronata), and Sonneratiace (Sonneratia alba). At sampling point 1, A. alba dominated with a density of 37 individuals/ha at tree level, 380 individuals/ha at pole level and 3100 individuals/ha at stake level. At sampling point 2, the tree level was dominated by A. alba with 142 individuals/ha, while R. mucronata dominated the pole and stake level with 1300 and 1467individuals/ha, respectively. At sampling point 3, the pole and stake level was dominated by A. alba with 167 and 933 individuals/ha respectively, while A. marina dominated the sapling level with 800 individuals/ha. At all stations, the density at stake level is greater than that tree level. Therefore, it is necessary to carry out conservation efforts in the form of protection combined with restoration by enrichment planting at all study locations to increase the diversity and density of mangrove vegetation.

Mangrove Trees

During the 1996 to 1997, large areas of mangrove forest in the Segara Anakan were cleared and converted into intensive shrimp-ponds. After one to two years, these shrimp-ponds failed and were abandoned. These abandoned ponds created large gap areas and canopy gaps, which were colonized by mangrove shrub and liana. The Segara Anakan mangrove also experienced heavy siltation, and there were tree cuttings from the remnant of the mangrove trees. This research aimed to study the colonization of mangrove vegetation at the abandoned-shrimp pond. Vegetation data were collected using rectangular plots of 25 m x 25 m with 4 replicates. The water qualities were also studied. The results revealed that the mangrove forests were composed of two layers: canopy tree and floor-vegetation. The gap areas triggered the pioneer species of mangrove shrubs and liana, Acanthus ilicifolius and Derris heterophylla, to colonize and dominate 100% of the mangrove forest floor. The mangrove trees consisted of natural and planted tree species. The natural trees were Sonneratia alba, Avicennia alba, and saplings of Aegiceras corniculatum, which  varied between 56 – 136, 4, and 4 individuals per ha, respectively. The planted trees were Rhizophora apiculata, which amounted to 4 – 12 individuals per ha, at the island of the ponds. These trees and saplings were entangled by the liana mangrove, which disturbed their growth. The A. ilicifolius and D. heterophylla prevented the mangrove tree propagules to grow, and they colonized and characterized those abandoned shrimp-ponds, which threatened the Segara Anakan mangrove ecosystem.

Abstrak : Rehabilitasi mangrove merupakan salah satu upaya yang dilakukan untuk mengurangi laju kerusakan hutan mangrove di Indonesia salah satunya di kawasan Teluk Gerupuk. Penelitian ini bertujuan untuk mengetahui kondisi mangrove hasil rehabilitasi di Teluk Gerupuk dengan mebandingkan struktur vegetasi mangrove di kawasan tersebut dengan ekosistem mangrove alami. Pelaksanaan penelitian dilakukan pada bulan April-Juni 2019 di dua kawasan hutan mangrove di pesisir selatan pulau Lombok yaitu hutan mangrove alami desa Pemongkong dan hutan mangrove rehabilitasi Teluk Gerupuk. Pengambilan data dilakukan dengan menggunakan metode transek berpetak dengan ukuran petak 10 x 10 m untuk tipe pohon, sub petak 5 x 5 m untuk tipe pancang, dan petak semai berukuran 2 x 2 m. Terdapat 11 spesies mangrove ditemukan di dalam plot penelitian dengan persebaran spesies yaitu 8 spaesies ditemukan di hutan mangrove alami Pemongkong dan hanya 7 spesies ditemukan di hutan mangrove rehabilitasi Gerupuk. Spesies mangrove yang dimaksud termasuk ke dalam 4 famili yaitu Avicenniaceae (Avicennia alba, A. marina, A. lanata), Rhizophoraceae (Ceriops decandra, C. tagal, Rhizophora apiculata, R. mucronata, R. stylosa), Rubiaceae (Scyphiphora hydrophyllaceae) dan Sonneratiaceae (Sonneratia alba, S. casiolaris). Struktur vegetasi kedua ekosistem sangat berbeda terlihat pada vegetasi penyusunnya. Hutan mangrove alami Pemongkong didominasi oleh jenis Sonneratia alba dan Avicennia alba yang memiliki Indeks nilai penting (INP) untuk tipe pohon dan pancang dengan nilai masing-masing 132,37 dan 141,52, sedangkan hutan mangrove rehabilitasi didapatkan INP tertinggi pada tipe pohon dan pancang yaitu jenis R. apiculata dan R. stylosa dengan INP berturut-turut 140,5 dan 116,41. Rehabilitasi hutan mangrove dengan metode yang selama ini dilakukan telah mengubah struktur vegetasi hutan mangrove di Pulau Lombok yang juga dapat mempengaruhi fauna asosiasi dan ekosistem sekitar mangrove. Oleh karena itu, diperlukan perencanaan serta analisis terlebih dahulu terhadap lokasi tujuan rehabilitasi mangrove agar untuk terbentuknya hutan mangrove rehabilitasi yang lebih sesuai dengan biota asosiasi dan ekosistem sekitar yang telah ada sebelumnya.Kata Kunci : Struktur Komunitas, Mangrove, Alami, RehabilitasiAbstract : Rehabilitation of mangrove vegetation was an effort in order to decrease the rate of mangrove ecosystem destruction.
