Abstract

Coastal city of Semarang is susceptible to the impact of coastal hazard due to its flat topographic condition. Various environmental problems are faced by Semarang involve tidal inundation, land subsidence, and floods during rainy season. This study was conducted to examine the potential economic losses caused by the sea level rise phenomenon. Distribution of inundated area mapped using Digital Elevation Model and Land Subsidence data. The Scenarios of International Panel on Climate Change (2007) sea level rises used to build a model of inundated area that notes by 2030 the rise of sea level rise at 13.4 cm. The inundated map was overlayed with landuse map to calculate the potential economic losses. The results show that the inundated area that occurred in 2030 was 1,718.2 ha with the potential economic losses Rp. 6,130 trillion. With the land subsidence scenario that happen at the area, inundated area increased to 5,171.3 ha with the eonomic potential loss about Rp. 28,724 trillion.

Abstract

Sea grass bed is an important ecosystem in coastal areas and small islands which plays important and effective roles as a protector of the coastal line and the safety of the mainland area of small islands. Physically, the roles of ecosystem were as erosion prevention, sediment trap and barrier of waves and currents. The existence of these ecosystems in the coastal regions and small islands was an important in enhancing the adaptive capacity of islands against natural disaster because the island serves as a natural protector. The aim of this research was to calculate and assess tha adaptive capacity of sea grass ecosystems growing in the waters of around the small islands in the group of Guraici. The research was conducted on 17 islands located in the group of Guraici islands. Measurement of adaptive capacity of sea grass ecosystem was done by analyzing 6 parameters, namely: Sea Grass Dimension Index (IDLn), Dominant Species of Sea Grass, Sea Grass Coverage Percentage (%), Number of Sea Grass Species, Substrate Type, Distance from The Point of Ecosystem. Sea Grass ecosystem adaptive capacity value was in the range between 0.0-1.0, with capacity of five categories of “very low, low, medium, high and very high”. These results indicated that sea grass ecosystem growing in the waters of around the islands in the island of group Guraici had adaptive capacity with values ranging between 0.0-0.59. The ranges of values were distributed into three categories of the adaptive capacities (very low, low and medium). A total of 13 islands had a capacity of sea grass ecosystem “medium”, the other three islands with capacity of “low” and one island with a capacity of “very low”.    Key words : Adaptive Capacity, seagrass ecosystem.

Abstract

ABSTRACTA study aimed to examine the status of sustainable management of coral reef in Pulau Hogow and Pulau Putus-Putus in Southeast Minahasa regency, North Sulawesi Province, was conducted in from July to September 2011. Diagnosis on the status of sustainable management of coral reef was presented in a sequence covering the ecological, economic, social, institutional and technological dimensions. In ecological dimension, the attribute of percentage of coral cover provided the largest contribution. In economical dimension, the largest contribution was provided by tourism guide, time used for coral reefs exploitation, dependency on the resource as a source of income and foreign tourists attributes. In social dimension, similar indications shown by the attributes of the number of locations which were potential for exploitation conflicts, level of education and efforts to repair the damage of coral reef ecosystems. On the institutional dimension, the contributions made by all attributes were almost even, with the highest is the tradition/culture and cooperation attributes. Similarly, in the technological dimension the contributions made attributes were almost even, with the highest contributions were from boat technology and technology post-harvest technology attributes. For overall dimensions of sustainability management of coral reefs, a map created in RAPFISH ordinate showed recommendation on the status of the sustainability.Keywords: sustainability, management, coral reef, dimension.ABSTRAKPenelitian ini bertujuan untuk menelaah status keberlanjutan pengelolaan te-rumbu karang di Pulau Hogow dan Putus-Putus Kabupaten Minahasa Tenggara Provinsi Sulawesi Utara, dilakukan pada bulan Juli-September 2011. Diagnosis status keberlanjutan pengelolaan terumbu karang dikemukakan secara berurutan mencakup dimensi ekologi, dimensi ekonomi, dimensi sosial, dimensi kelembagaan dan dimensi teknologi. Dalam dimensi ekologi atribut persentase penutupan karang memberikan kontribusi terbesar. Untuk dimensi ekonomi kontribusi terbesar diberikan atribut pe-mandu wisata, waktu yang digunakan untuk pemanfaatan terumbu karang, ketergan-tungan kepada sumberdaya sebagai sumber nafkah dan wisatawan mancanegara. Di-mensi sosial indikasi serupa ditunjukkan oleh atribut-atribut jumlah lokasi potensi kon-flik pemanfaatan, tingkat pendidikan dan upaya perbaikan kerusakan ekosistem terum-bu karang. Pada dimensi kelembagaan kontribusi yang diberikan atribut-atribut merata, tetapi yang tertinggi adalah tradisi/budaya dan koperasi. Demikian juga pada dimensi teknologi, kontribusi yang diberikan atribut-atribut merata, dengan kontribusi tertinggi adalah atribut teknologi perahu dan teknologi pasca panen. Untuk semua dimensi keberlanjutan pengelolaan terumbu karang, hasil pemetaan yang dilakukan dalam ordinasi RAPFISH menunjukkan status keberlanjutan yang baik untuk dilakukan.Kata kunci: keberlanjutan, pengelolaan, terumbu karang, dimensi.

Abstract

ABSTRACTCommunity structure of target fishes was analyzed to understand their response to different conditions of coral reefs in several places of Hugow and Putus-Putus islands. This study focused on species abundance and diversity including Shannon-Wiener’s species diversity (H’), species richness (SR), species evenness (J’) and dominance (d) indices, respectively. A multivariate analysis was used for the classification or correspondence factorial analyses. The result recorded 4,501 individuals belonging to 52 species of target fishes. Both cluster and correspondence analyses clearly recognized 3 groups of target fish with 2 major controlling factors for the development of these 3 ecological groups, i.e. coral reef conditions and geographic position to the hydrodynamic condition.ABSTRAKStruktur komunitas ikan target dianalisis untuk melihat respon ikan target terhadap perbedaan kondisi terumbu karang di beberapa lokasi Pulau Hogow dan Putus-Putus. Penelitian ini dilakukan pada bulan Oktober 2010 dengan pengambilan data di 6 stasiun. Dalam penelitian ini telah dikaji variabel komunitas seperti kelimpahan dan keanekaragaman spesies termasuk indeks keanekaragaman spesies Shannon-Wiener (H’), indeks kekayaan spesies (SR), indeks kemerataan spesies (J’) dan indeks dominasi (d). Untuk melihat assemblage ikan target dilakukan analisis multivariat baik analisis klasifikasi maupun analisis faktorial koresponden. Dalam penelitian ini diperoleh 4501 indidu yang termasuk dalam 52 spesies ikan target. Analisis multivariat baik analisis cluster maupun analisis koresponden telah memisahkan dengan jelas 3 grup ikan target, dimana terdapat dua faktor utama pengendali pembentukan 3 grup ekologis ini yakni faktor kondisi terumbu karang dan faktor posisi lokasi terhadap kondisi hidrodinamika perairan.

Abstract

The majority of fishermen are the small-scale group who are depending on marine resources which utilization results are unsettled so that this group vulnerable to a low welfare state. On the other hand, the abundant marine resources in the mangrove ecosystem have not been able to be managed optimally to improve the welfare of fishermen's household. Therefore, the purpose of this study is to measure the welfare state of fishermen's household around the mangrove ecosystem. This research was conducted in the Khairiah Mandah Village from December 2019 to January 2020 using a survey method. The technique was determining respondents using purposive sampling with 39 fishermen consisting of 13 fishermen who catch fish, 13 fishermen who catch shrimp, and 13 fishermen who catch crabs. Data analysis uses analysis of the level of family welfare with indicators of a prosperous family according to BKKBN. The results showed that the fishermen around the mangrove ecosystem were mostly in the Prosperous Family I group with a percentage of 56%. Besides, fishermen families who are in the Prosperous Family II group are 31%, Prosperous Family III is 8%, Pre-Prosperous Family is 5%, and none are included in the Prosperous Family III Plus group.
