“…Salah satu tekanan yang saat ini sedang mengancam keberlanjutan wilayah pesisir adalah adanya kenaikan muka air laut (Wirasatriya, Hartoko, & Suripin, 2006). Kenaikan permukaan laut merupakan juga masalah yang berdampak pada terjadinya masalah alam dan berdampak pada kehidupan ekonomi penduduk di sekitar pantai (Karondia, Handoko, & Hapsari, 2019). ENSO atau El-Niño Southern Oscillation dapat menjadi representasi dari bagian penting perubahan iklim global karena mempengaruhi cuaca dan iklim pada skala global.…”

Kenaikan permukaan air laut atau sea level rise akibat perubahan iklim adalah salah satu masalah serius pada saat ini. Air laut yang bersentuhan langsung dengan wilayah pesisir membuat wilayah tersebut menjadi rentan terhadap lingkungan. Salah satunya Laut Jawa di Indonesia dengan cakupan yang cukup luas akan memberi banyak dampak di wilayah pesisir Pulau Jawa bila adanya kenaikan permukaan laut. Untuk pengamatan tersebut dilakukan perhitungan sea level anomaly (SLA) agar membantu dalam memberi pemahaman permukaan laut serta perubahannya dari waktu ke waktu. Perhitungan SLA menggunakan data dari Satelit Cryosat-2. Cryosat-2 adalah satelit altimetri yang dirancang untuk misi pengamatan lapisan es dan oseanografi yang baik di laut. Serta satelit yang memiliki muatan utama SIRAL (SAR Interferometer Radar Altimetri) dan tingkat akurasi yang sangat baik walaupun tidak memiliki micorwave radiometer. Dari penilitian ini diharapkan mengetahui sea level variability permukaan Laut Jawa dari tahun 2011 sampai dengan 2019. Didapatkan berdasarkan perhitungan regresi linier tren SLA Cryosat-2, Laut Jawa mengalami penurunan sebesar 27,9746 mm dengan laju -3,55 mm/tahun. Hal ini disebabkan oleh fenomena El-Niño Southern Oscillation (ENSO). Hasil perhitungan koefisien korelasi dari detrended sea level anomaly (SLA) dan Multivariate ENSO Index (MEI) adalah -0,6451 yang menandakan korelasi antara keduanya memiliki hubungan cukup namun tidak searah. Semakin tinggi index MEI maka nilai SLA akan semakin rendah di Laut Jawa, begitupun sebaliknya.

“…Sea level rise is one of the consequences of climate change due to anomalous increases in global temperature of around 1 o C. The global average sea level has increased by about 20 cm since the end of the 19th century [10], both for the community, built areas, and the environment, which causes sea level also to change when there is an exchange of mass between the reservoir, ice or the terrestrial atmosphere and the ocean [11]. Several global sea-level rises (GMSL) studies using satellite altimetry data show that the rate of sea-level rise has reached 3.4 mm / year since 1993 [12]. Climate change in coastal areas such as sealevel rise, increased incidence and intensity of storms and tides is a major concern.…”

The phenomenon of climate change causes cities in coastal areas to be threatened by rising sea levels. Semarang is one of the coastal cities in Indonesia which is threatened by sea level rise. One of the consequences is tidal flooding in coastal areas of Semarang. Semarang as an old city has a cultural heritage area with historic buildings. The purpose of this paper is to analyze the current condition of the Semarang Old City National Cultural Heritage Area and the impact experienced by the tidal flood. The method used in this research is to conduct a literature study and field observations which are analyzed by spatial analysis of buildings in historical areas and descriptive analysis. This study shows that tidal flooding is a threat to cultural heritage buildings. The condition of the land in the city of Semarang, which is decreasing due to land subsidence and rising sea levels, has made the potential for damage to buildings in the old city area even greater.

“…In the West Pacific region, geostrophic forcing causes seawater to accumulate along the western margin of the Pacific Basin, resulting in sea levels and rates of sea level rise in Southeast Asia that are higher than the global average (Weller et al, 2016). For example, the rate of sea-level rise in coastal Indonesia from 1992 to 2015 was approximately 7 mm per year (Surya et al, 2019), and climate change models predict a sea level rise of 74 cm by 2100 (Karondia et al, 2019) which would inundate large areas of coastal mangrove. Shifting tidal ranges will impact biodegradation of LWD through changes in the distribution of wood-boring guilds.…”

There has been limited research on the breakdown, recycling, and flux of carbon from large woody detritus (LWD) in mangrove forests. The breakdown of LWD is caused by guilds of terrestrial and marine biodegrading organisms that degrade wood at a range of rates and efficiencies. Spatial variations in environmental factors within mangroves affect the distribution and community of biodegrading organisms, which, in turn, impacts carbon flow and sequestration. We reveal the role of biodegrading organisms in LWD breakdown and the environmental factors that influence the distribution of biodegrading guilds within a mangrove forest in South East Sulawesi that supports a diversity of mangrove species typical of Indonesian mangrove forests, which constitute 20% of Global mangrove cover. Within the high intertidal regions, terrestrial biodegradation processes dominated upon LWD. After 12 months exposure on the forest floor, experimental wooden panels in these areas remained unchanged in mass and condition. In the low intertidal region, marine wood-boring animals belonging to the family Teredinidae were the dominant biodegraders of LWD, and their activity reduces LWD volume and speeds up the loss of LWD volume. More than 50% of the experimental wooden panels’ weight in these areas was lost after 12 months exposure on the forest floor. Although different biodegrading guilds occupy the same LWD niche, their distribution throughout the mangrove forest is influenced by inundation time. The change of biodegrading guilds within LWD between the terrestrial and the marine organisms was distinct, creating a biodegradation boundary in a distance as narrow as 1 m on the mangrove forest floor. These results are important, as rising sea levels have crucial implications for biodegrading guilds. A full understanding of factors affecting the biodegradation processes of LWD in mangrove forests is critical to accurately assess mangrove carbon stores and the fate of mangrove derived carbon.
