“…Kelurahan Mangunharjo merupakan wilayah pesisir dengan panjang pantai 3,5 km2 yang dibatasi oleh Sungai Bringin di sebelah barat dan Sungai Plumbon di sebelah timur (Setiyowati et al, 2016). Kawasan pesisir yang berekosistem mangrove di Kelurahan Mangunharjo diketahui meningkat pada tahun 2012-2017, secara signifikan dari 19,78 Ha menjadi 68,47 Ha (Nugraha et al, 2018). Kondisi lahan mangrove di Kelurahan Mangunharjo sebagian besar merupakan kawasan tambak (Zaky et al, 2012).…”

Tugu sub-district has a mangrove ecosystem that is better than the other three sub-districts in Semarang City. The improvement of the mangrove ecosystem in Mangunharjo Village became the main of priority for mangrove rehabilitation This study aimed to determine the level of diversity of mangrove species found in the mangrove ecosystem of Mangunharjo Sub-District, Tugu District, Semarang City based on the zonation. The study was conducted in February-March 2018. Sampling using a combination method, that are systematic sampling with vegetation analysis techniques using quadrat sampling technique. There are three data collection stations determined based on the distance from the coastline to the mainland. Data were analyzed using quantitative descriptive statistics. The results showed that the diversity of mangrove species found in Mangunharjo Village had a low to moderate diversity level (0.72-1.32). The mangrove ecosystem in Mangunharjo is actually artificial ecosystem, with the type and number of mangroves dominated by Rhizophora mucronata and Avicennia marina. There are seven mangrove species found in the open zone, four species in the middle zone and four species in the land zone. Kecamatan Tugu memiliki ekosistem mangrove yang masih baik dibandingkan dengan tiga kecamatan lainnya yang berada di Kota Semarang. Perbaikan ekosistem mangrove di Kelurahan Mangunharjo menjadi prioritas utama rehabilitasi mangrove. Penelitian ini bertujuan untuk menentukan tingkat keanekaragaman spesies mangrove yang terdapat di ekosistem mangrove Kelurahan Mangunharjo Kecamatan Tugu Kota Semarang berdasarkan zonasinya. Penelitian dilakukan pada bulan Februari–Maret 2018. Pengambilan sampel menggunakan metode kombinasi, yaitu antara systematic sampling dengan teknik analisis vegetasi menggunakan quadrat sampling technique. Terdapat tiga stasiun pengambilan data yang ditentukan berdasarkan jarak dari garis pantai hingga daratan. Data dianalisis secara statistik deskriptif kuantitatif. Hasil penelitian menunjukan bahwa keanekaragaman spesies mangrove yang terdapat di Kelurahan Mangunharjo mempunyai tingkat keanekaragaman rendah hingga sedang (0.72-1.32). Hal ini dikarenakan ekosistem mangrove wilayah Mangunharjo merupakan ekosistem buatan, dengan jenis dan jumlah mangrove yang dominasi oleh Rhizophora mucronata dan Avicennia marina. Terdapat tujuh spesies mangrove yang ditemukan pada zona terbuka, empat spesies pada zona tengah dan empat spesies pada zona daratan.

“…The area has a narrow bay with a width of only 7-10 km; the bottom of the shelf is irregular and decreases abruptly towards the Cape Kri. This research was conducted during these months because it corresponds to the end of the western Monsoon in Raja Ampat, when the SST level is at its highest and has the potential to have a significant impact on the condition of the biodiversity and habitat in this region (Mangubhai et al 2012;Nugraha et al 2018).…”

Abstract. Siburian RHS, Tapilatu JR, Tapilatu ME. 2023. Discovery of habitat preferences and community structure of Echinoderms in Kri, Raja Ampat, Indonesia. Biodiversitas 24: 3968-3976. Raja Ampat, located in Papua, Indonesia, is home to one of the most diverse coral reef ecosystems and is a component of the Coral Triangle. The coral in Raja Ampat is still considered to be in good health. Although the marine fauna in Raja Ampat is pristine and diverse, there have still only been a few studies in this region. The scientific research on the Echinoderms in Raja Ampat is limited, particularly as a primary input for data research. In this study, we present Echinoderm's habitat and community structure in the Kri coastal area at Mansuar Island based on the data collected at field sampling. From January to February 2023, data were collected intensively during morning and afternoon low tide for three repetitions each, at 5-10 m depths. We conducted morphological species identification. Asteroidea, Holothuroidea, Echinoidea, and Crinoidea were found to be the four major classes of Echinodermata that dominated the sampling area, with a total of 20 species and 180 individuals. Each Echinodermata species has its preferred Kri coastal habitat based on its food supply, unique behavior, and body structure. In addition, the result indicates that this region has a moderate diversity level, with low dominance and moderate to high uniformity. This research provides new information on the ecology of Echinoderms in eastern Indonesia, particularly in Raja Ampat.

“…For more than a century, Semarang has been suffering from land subsidence at a massive rate, from 6 to 19 cm per year [17,18,55,[58][59][60][61][62]. Besides, development also causes various interrelated disasters and hazards, such as coastal erosion, flooding, coastal flooding, and damage on mangrove ecosystems [61,[63][64][65]. These hazards and damages have deteriorated the coastal environment by widening the coverage area of coastal flooding, increasing the salinization of freshwater, increasing permanently inundated areas, and damaging coastal settlements, basic facilities, and infrastructure.…”

Coastal areas have been growing massively worldwide. The fast growth also affects the land value in either a positive or a negative way. Many scholars have studied land value and the factors that affect it in areas prone to sudden-onset disasters. In contrast, studies on urbanized coastal areas that suffer from slow-onset disasters are still lacking. Using a case study from Semarang City in Indonesia, this research aims at ameliorating this limitation. To comprehensively understand the aim, two research questions are addressed: (1) What is the distribution of land value in urbanized coastal areas? (2) How do the different distribution factors determine the land value? Based on in-depth interviews with key persons, map analyses, and desk studies, this research discovers that land value is distributed randomly among coastal areas. The dynamics of land value are determined by road access, distance, and accessibility to the city center and CBD, public facilities, transportation facilities, population composition, physical environment, and disasters. Surprisingly, the coastal areas in Semarang that experience combined disasters showed that disasters could not decrease the land value; the value in some areas is constant or even increasing. This shows the different impacts of disasters on land value for slow-onset disasters and sudden-onset disasters.
