Abstract

The research about the identification of mangrove physical condition and the change of mangrove area has aims are knowing of mangrove physical condition and the change of mangrove area in the coastal region southern part of Padang city. The method used in this research is the field survey and multi-temporal satellite imagery analysis in 2001 and 2018 year. Based on the field survey at the date of August 18, 2017 generally the mangrove that found in research location i.e Rhizophora Apiculata, Rhizophora mucronata, Sonneratia alba, and Nypa. The spatial distribution of the mangrove ecosystem is dependent on the ecological conditions of the area as reflected by the types of mangrove vegetation that grows and develops in the research location. A decrease in mangrove area that occurred between of 2001 to the 2017 years i.e in the coastal region of Bungus bay i.e 5.54 ha, where the decrease in mangrove area occurred because some mangrove plants were cut down and made the settlement land, while in the region of Sungai Pisang bay happen to increase in mangrove area i.e 36.12 ha, where the increase in mangrove area occurred because of the region obstructed by big waves of the sea (protected small the islands).

Abstract

The mangrove ecosystem is an ecosystem that grows above the brackish marshes that are located on coastlines and influenced by the tides of the sea water. The conditions of the mangrove ecosystem continue to experience widespread decline and change in density especially on the coastal area of Bungus Teluk Kabung. The study was conducted in June ? August 2019. The purpose of this research is the major analysis of the rate of change of mangrove land cover, analysis of perception/community opinion about the conditions and efforts made by the Government of the mangrove and analysis of the condition of the mangrove ecosystem. The method used is a quantitative approach to descriptive. The result is a mangrove land cover of 2009 covering an area of 80.71 ha while the year 2019 is 60.35 ha, the rate of change (-25,23%/10 year), the change in mangrove area with a change rate of-100% found in the location of  Teluk Sirih where the year 2009 (8, 82ha), and the year 2019 (0 ha). The change occurred due to the construction of the PLTU of Teluk Sirih. With the increase of mangrove ecosystem in the area of Pertamina Jetty because of the rehabilitation of local government. Its expansion in the year 2009 (3.06 ha) became the year 2019 (3.96 ha) with the addition of 0.90 ha and the rate of change of 29.41%.  NDVI values of 2009 in 0.60 with normal vegetation density conditions and the year 2019 NDVI values in 0.42 with good vegetation density conditions.

Abstract

Mangrove is a plant that can live in tidal areas and form a community of independent vegetation, ranges to various disorders, especially marine resource management that is not environmentally friendly causing damage to the Mangrove forest. Thus researched to know the condition, the rate of change in land area and public response to the mangrove ecosystem implemented in August 2019 using Phantom 4 Drone data and a descriptive method Quantitative. The results were adopted, namely, the condition of the mangrove ecosystem was declared normal (0.22) in the year 2009 using NDVI value classification, as well as the year 2019 NDVI value of 1 in the condition is very good. The area on land cover amounted to 406.61 ha in 2019, while the year 2009 amounted to 406.69 ha with a change of-0.08 ha. Mangrove conditions with an area of 79.13 ha in 2009, a decline in 2019 of 60.01 ha, a change of-19.12 ha (-24.16%). The mangrove ecosystem is getting worse because of the road construction that causes some material to fall into the mangrove area that makes the sedimentation wider, as occurs in the segment 3 The change of mangrove overflow from the year 2009 (21.60 ha) 19.83 ha in the year 2019. People are still promoting the economy compared to the survival of mangroves because the existence of mangroves is considered economically beneficial for them.

Abstract

Seagrasses in the Air Bangis Archipelago, west coast of Sumatra were found growing in sandy muddy substratesof the shallow coastal waters at depth of 0.3-2.5 m, dominated by degraded coral reefs around the off-shoreislands. Two species; Enhalus acoroides (L.f) Royle and Thalassia hemprichii (Ehrenb) Aschers were observed atPulau Unggas, Pulau Pasir Panjang and Teluk Tapang. Halodule uninervis (Forssk) Aschers was observed in twolocations; Pasir Panjang and Teluk Tapang. The occurrence of this species is unknown previously and therefore itis a new flora record for Sumatra. With this new record, Sumatra has six species of seagrasses, contributing tohalf of total number of seagrasses occurring in Indonesia. According to leaf width measurements, two morphologicalvariants (narrow and wide leaved) can be distinguished for Halodule uninervis. In addition, descriptions of thespecies and their habitat characteristic are provided.

Abstract

Komposisi dan vegetasi ekosistem mangrove pada suatu kawasan yang tumbuh di pulau-pulau kecil umumnya tidak sama dan tergantung kepada ekologi dari ekosistem pulau tersebut. Tujuan ini penelitian ini adalah untuk memperoleh informasi dari komposisi, struktur vegetasidan jenis mangrove yang hidup pada masing-masing pulau kecil di kawasan Pasaman Barat. Metode ang digunakan adalah survei lapangan untuk mendapatkan jenis, komposisi dan struktur vegetasi dari masing-masing pulau dengan melakukan teknik  transek kuadrat. Pada penelitian yang telah dilakukan di beberapa tiga pulau di Kabupaten Pasaman Barat (pulau Taming, pulau Harimau, dan pulau Panjang) menunjukkan bahwa ke tiga pulau tersebut telah teridentifikasi tumbuhan 15 spesies, 11 famili, 2 famili dan 5 spesies merupakan masuk pada kategori mangrove sejati dan spesies dominan adalah R. stylosa dengan indek nilai penting (IVi) untuk tingkat pohon 192,88% di pulau Taming, pulau Harimau 36 spesies, 24 famili, 9 spesies dan 4 famili masuk pada mangrove sejati, spesies dominan R. apiculata, (IVi ) adalah 229,82%, sedangkan pada pulau Panjang 18 spesies, 14 famili, dimana 5 spesies dan 2 famili masuk kategori mangrove sejati, spesies dominan R. mucronata dengan (IVi ) 92,98%. Dari masing-masing pulau menunjukkan komposisi, struktur vegetasi dan kedominan speises yang berbeda dan ini disebabkan oleh perbedaan  subtrat yang dominan yang terdapat pada masing-masing pulau. Kata kunci: komposisi; vegetasi; mangrove, pulau-pulau kecil; Pasaman Barat Composition and vegetation of mangrove ecosystem in an area including that grown in small islands is different and depends on ecology and ecosystem of the islands. The purpose of the research is for getting the information of composition, vegetation structure and mangrove type that grown an each small islands in west Pasaman area. The method use was a survey of the field to get the type, composition and vegetation structure of each island by using transectsquares technique.In the research that has been done on several islands in the West Pasaman (Taming Island, Harimau Island, and Panjang Island), have been identified plants on Tamang Island that had 15 species and 11 families, which 2 families and 5 spesies were categorized as true mangroves and the dominant spesies is R. stylosa with important value index (IVi) is 192.88%, on Harimau Island found 36 species and 24 families, which 9 species and 4 families were categorized as true mangroves and the dominant is R. apiculata with 229.82% (Vi), while on Panjang Island found 18 plant species and 14 families, which 5 species and 2 families were categorized as true mangroves, the dominant species is R. mucronata with 92.98%. From each island showed composition, vegetation structure and different dominant spesies and this different is caused by the dominant substrate fand on each island.

Abstract

Mangrove, as one of the most unique ecosystems, is a great natural resource potential with high productivity and biodiversity able to adapt to harsh areas between the sea and coast. Its destruction rate is very mild as it is estimated to 1% each year (Ong et al., 1991) and 0.7-3% per year (Pedleton et al., 2012). The destruction of mangrove is usually related with human population density (Alongi, 2002). Widespread mangrove destruction affects the loss of biodiversity and other resources and the functioning of the ecosystem. The huge potential of mangrove must be preserved by managing, maintaining and providing costs to protect and improve ecosystems. This study aims to measure Kuala Langsa community members? willingness to pay for the preservation and repairationof degrading mangrove. To achieve this goal, Contingent valuation methods was used in this study. Of the 131 respondents involved in this study, 112 or 85.496%  are willing to pay for the preservation of mangrove. While those unwilling to pay account for 19 or 4.504% . WTP with the households 669 earned by  is Rp 18,821,512,200/month or Rp 225,858,146,400/year.
