Abstract

Real work lecture is a form of activity carried out by a college of community service activities in a certain area or an educational institution. provide real work experience in the field in the field of forming an independent attitude and responsibility in the implementation of work and activities in the field. In addition, KKN also aims to assist the community in improving their level of knowledge and skills so that it is expected to improve the welfare of the people in the area. KKN activities run well and smoothly. This is due to the enthusiasm of the community including the children there who are passionate about participating in every activity we carry out. The activities carried out at namely the socialization of the importance of education, the socialization of the importance of risk behavior, the mastery of Indonesian Language Mastery in Era 4.0, tutoring and discussion, and the river of life. It is hoped that the implementation of the Community Service programs can be useful and applied in the lives of all parties concerned.

Abstract

Coastal area is defined as a transitional area between land ecosystems and marine ecosystems. Coastal areas are very vulnerable to environmental pressures, both on land and at sea. One form of pressure that threatens the sustainability of coastal areas almost all over the world is the phenomenon of sea level rise. The phenomenon of sea level rise itself is a result of the expansion and contribution of ice due to increased of melting ice as a result of global warming. It is predicted that in 2100 there will be a rise of sea level that reach 0.26 to 0.98 meters. Sea level rise can be analyzed using a trendline based on monthly slopes to determine the average of sea level rise per year. In addition, to determine the vulnerability of coastal areas to sea level rise, it can be determined through two aspects: aspects of geophysical vulnerability and aspects of socio-economic vulnerability.

Abstract

Marine heatwaves (MHWs) are extreme warming events in the ocean when the temperature detected is above the 90th percentile of climatological temperature for at least five consecutive days. MHWs events can extend up to thousand kilometers and have been detected in the subsurface layer. MHWs are described by metrics (frequency, duration, and cumulative intensity). The purpose of this study was to determine the characteristics of MHWs in the subsurface layer for 27 years (1993-2019). The data used in this study is the sea water temperature data of the depth 0,4m-763m from Marine Copernicus Global Ocean Physics and Niño 3.4 indices. The method used in this study is a statistical method to calculate the average and trend of the MHWs metric. The results of this study denotes that the occurrence of MHWs at a depth of 0.4m-92m is caused by ENSO (El Niño Southern Oscillation) positive phase (El Niño) with a delay of 7-8 months and at a depth of 109m-763m caused by negative phase ENSO (La Niña) with a delay of 1-3 months. It was also found that the frequency of MHWs was higher at a depth of 418m-763m with a maximum value is 2,6 events/year, the duration of MHWs was greater at a depth of 0,4m-77 m, with a maximum value of duration is 30-32 days/year, and the maximum cumulative intensity of MHWs events for 27 years is 90˚C. During the 1993-2019, the trend of frequency, duration, and cumulative intensity of MHWs in the subsurface layer of south Java Sea has significantly increased.

Abstract

The waters of West Sumatera that face directly into Indian Ocean is strongly influenced by Indian Ocean Dipole (IOD) phenomenon which caused an anomaly of sea surface temperature (SST) and affect rainfall intensity in the West Sumatera Province. This research was aimed to know the effect of IOD on the distribution and anomaly of SST and rainfall intensity in West Sumatera. Data processing methods in this research is using statistical and descriptive. The data used in this research are NOAA OI-SST, Dipole Mode Index (DMI), and rainfall data from BKMG. The results showed that IOD positive occured in October 2018 and the IOD negative occured in July 2016. During the positive IOD, SST distribution values were 28 ˚C – 28,8 ˚C and SST anomaly values were ​​-1,2 to -0,4, in the negative phase the distribution of SST values were 29,8 ˚C – 30,35 ˚C and the SST anomaly values were 0,15 to 0,7. The rainfall intensity during positive IOD phase is 157 mm/month and during negative IOD phase is 525 mm/month.

Abstract

     This study aims to investigate the interannual variability of Sea Level Anomaly (SLA) along the western coast of Sumatra waters, focusing on the influences of the El Niño-Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD) in modulating SLA patterns. Using 31 years (1993-2023) of a gridded dataset from Copernicus Marine Service (CMS) and climate indices as the reference, the interplay between SLA and climate modes (ENSO and IOD) was determined through lag/lead correlation and spatial distribution analysis. The analysis shows a clear inversive relationship between ENSO and SLA, with a one-month delayed negative correlation (r= -0.41), indicating that SLA increases during the La Niña phase due to shifting in atmospheric and oceanic conditions. Similarly, SLA exhibits a negative correlation with DMI (r= -0.46) without any lag, suggesting a rapid response of SLA to IOD. Spatial analysis further demonstrates that ENSO and IOD most strongly influence SLA along Sumatra’s coast within the first 1–3 months. These findings reveal that ENSO and IOD modulate SLA variability with distinct spatiotemporal characteristics, providing crucial insights for understanding coastal dynamics and enhancing mitigation strategy for sea level-related disasters in the western coastal region of Sumatra

Abstract

Kerang darah (Anadara granosa) merupakan salah satu biota bahari yang banyak ditemukan dan dikonsumsi oleh masyarakat di sekitar kawasan pesisir. Sebagai biota filter feeder, kerang dapat terkontaminasi oleh berbagai macam bakteri, khususnya bakteri Coliform. Penelitian ini bertujuan untuk mendeteksi keberadaan bakteri Coliform pada kerang darah (A. granosa) yang diperoleh dari perairan Bagan Siapiapi, Riau. Bakteri Coliform dikenal sebagai salah satu indikator biologis yang sering digunakan untuk mengevaluasi tingkat pencemaran air dan keamanan pangan. Dalam analisis penanganan sampel, sampel kerang darah diambil secara langsung, diolah di laboratorium, dan dianalisis menggunakan media Endo untuk mendeteksi dan mengidentifikasi keberadaan bakteri Coliform. Pengamatan dilakukan terhadap morfologi koloni bakteri meliputi warna, bentuk, tepian, dan elevasi. Hasil penelitian menunjukkan keberadaan tiga isolat koloni dengan jumlah dan karakteristik yang berbeda. Isolat 1 memiliki 26 koloni dengan bentuk tidak beraturan, warna merah muda kekuningan, serta permukaan cembung. Isolat 2 menunjukkan 21 koloni dengan karakteristik serupa, tetapi warna lebih merah. Isolat 3 memiliki jumlah koloni tertinggi, yaitu 60 koloni/ml, dengan bentuk melingkar dan warna merah muda. Jumlah koloni bakteri Coliform yang ditemukan telah melampaui ambang batas maksimum cemaran mikroorganisme yang diatur oleh Badan Pengawas Obat dan Makanan Republik Indonesia, sehingga mengindikasikan risiko tinggi bagi kesehatan masyarakat. Penelitian ini menyoroti pentingnya pengelolaan sanitasi perairan dan pengujian mikrobiologi pada produk perikanan untuk melindungi kesehatan konsumen dari kontaminasi mikroba.
