Abstract

Shoreline changes could occurred because of hydrodinamically nature in coastal zone. The purpose of this study is to identify and approximating rate of shoreline changes which occurred in Karimun Besar Island. This study used to analyzed shoreline changesbased on remote sensing (satellite) data that processed by GIS (Geographic Information System). Then, to analyze the rate of its shoreline changes using DSAS (Digital ShorelineAnalysis System) with LRR (Linear Regression Rate) statistic method. The result found that shoreline has changes through 25 years (1991-2016) that abrasions are 1,63m/y and accretions are 3,78m/y.Keywords : Shoreline Changes, Satellite Data, DSAS

Abstract

In early January 2021, Tanjungpinang was hit by floods due to extreme rainfall intensity, causing the affected communities to suffer material and non-material losses. The flood has occurred from 2011 to 2021. To minimize the impact of flood events, it is necessary to study the characteristics of rainfall both temporally and spatially. This is considered important because with this information the public can anticipate the impact of extreme rainfall at a certain time and location. This study aims to identify the Spatio-temporal characteristics of extreme rainfall in Tanjungpinang City which often causes floods. However, to identify the characteristics of rainfall, long data is needed. This study uses CHIRPS (Climate Hazards InfraRed Precipitation with Station) satellite data because the rainfall observation data at the Raja Haji Fisabilillah station is not available for 2012. The identification results show that the correlation criterion (R) value between rainfall observation data and CHIRPS satellite data is 0.688. This value is interpreted as "strong" to be used as an alternative study data. GEE (Google Earth Engine) as a cloud-based platform is used to identify the spatial and temporal characteristics of extreme rainfall. From the results of temporal identification, it is known that extreme rainfall occurs in January, April, and December. The results of spatial identification indicate that the area that has the highest average maximum rainfalls at the Bukit Bestari District area of 156.60 mm/day. This can then be confirmed by looking at the documentation of flood events that often occur in the area.

Abstract

Ecosystem-based coastal protection offers a strategic approach to mitigating the impacts of climate change, particularly in small island contexts. This study integrates remote sensing and geospatial analysis to estimate blue carbon stocks in the mangrove ecosystems of Dompak Island, Tanjungpinang, using Google Earth Engine (GEE) and Sentinel-2 satellite imagery. Through the application of the Normalized Difference Vegetation Index (NDVI) and an empirical model for Above Ground Biomass (AGB), spatial carbon stock distributions were generated and classified into three functional zones: conservation, restoration, and critical protection. Results reveal that areas with moderate vegetation exhibit the highest carbon stock (32.00 tons/ha), suggesting ongoing biomass accumulation. This spatial analysis informs a zoning framework that supports ecosystem-based infrastructure planning. The integration of carbon mapping with adaptive civil engineering strategies demonstrates a scalable model for climate-resilient coastal development in vulnerable regions.

Abstract

This study presents a technical overview of a coastal road embankment constructed in a tidal zone of a small island in Indonesia. The objective is to document the integrated application of non-woven geotextile and multi-level gabions as a stabilization system on moderately strong subgrade soils affected by tidal dynamics. The research method involved descriptive analysis based on as-built documentation and field data, including California Bearing Ratio (CBR) tests at three locations. The results showed CBR values ranging from 41.11% to 60.84%, which classify the subgrade as moderately strong. Despite this, the use of geotextile was essential to prevent mixing of soft subgrade and fill material, provide load distribution, and ensure drainage, while the gabion structures acted as lateral confinement and toe protection against erosion caused by tidal infiltration. The findings suggest that soil strength alone is insufficient for coastal infrastructure design, and integrated stabilization measures should account for environmental forces such as saturation cycles and hydraulic pressure. This case offers a practical insight into adaptive geotechnical strategies for road construction in tidal zones, serving as a reference for similar projects in archipelagic and low-lying coastal regions.

Abstract

Masyarakat Cerdas adalah program inovatif dari Fakultas Teknik dan Teknologi Kemaritiman UMRAH yang bertujuan memberdayakan masyarakat Kepulauan Riau melalui pemanfaatan teknologi. Desa Toapaya Utara dipilih sebagai mitra karena potensinya di sektor pertanian, perkebunan, perikanan, dan peternakan, namun demikian terdapat tantangan seperti penerangan yang kurang memadai. Untuk mengatasi hal ini, UMRAH memperkenalkan Lampu Otomatis Berbasis Energi Surya dengan IoT (Internet of Things), yang menyediakan penerangan ramah lingkungan dan sistem pemantauan real-time. Pemberdayaan dilakukan melalui kegiatan penyuluhan, pelatihan, dan peningkatan kapasitas, masyarakat dilibatkan dalam pembuatan dan penerapan teknologi ini. Program ini berhasil meningkatkan pengetahuan masyarakat dan membuktikan bahwa lampu otomatis dapat mendukung produktivitas pertanian serta kehidupan sehari-hari. Dengan demikian, program ini tidak hanya meningkatkan kualitas hidup masyarakat tetapi juga merefleksikan komitmen UMRAH dalam menjalankan Tri Dharma Perguruan Tinggi dan memperkuat kolaborasi akademisi-masyarakat untuk solusi berkelanjutan.

Abstract

Kegiatan Pengabdian kepada Masyarakat ini dilaksanakan sebagai implementasi mata kuliah Pengantar Ilmu Teknologi Kemaritiman (PITK) yang bertujuan untuk meningkatkan pemahaman dan kepedulian siswa sekolah dasar terhadap lingkungan laut melalui media pembelajaran berbasis Augmented Reality (AR). Gap kegiatan terletak pada belum terbangunnya keterhubungan antara pembelajaran kemaritiman di perguruan tinggi dan penerapannya di tingkat sekolah dasar, khususnya di wilayah pesisir. Untuk menjembatani kesenjangan tersebut, dikembangkan flipbook interaktif berbarcode AR yang menampilkan visualisasi biota laut lokal sebagai media belajar kontekstual. Metode kegiatan meliputi penyuluhan, demonstrasi, refleksi, dan observasi terhadap siswa kelas V SDIT As-Sakinah Tanjungpinang pada 7 Mei 2025. Evaluasi dilakukan secara deskriptif menggunakan dua indikator utama, yaitu (1) pemahaman konseptual siswa terhadap ekosistem laut melalui jawaban reflektif dan diskusi, serta (2) kepedulian siswa terhadap pelestarian lingkungan laut berdasarkan respons sikap dan partisipasi selama kegiatan berlangsung. Hasil menunjukkan bahwa penerapan AR mendorong keterlibatan aktif siswa, memperkuat pemahaman terhadap konsep ekosistem laut, dan menumbuhkan kesadaran ekologis sejak dini. Kegiatan ini berkontribusi dalam mengembangkan model pembelajaran lintas jenjang berbasis teknologi yang memperkuat literasi maritim di wilayah pesisir.

Abstract

Tanjung Pinang, the capital city of Kepulauan Riau Province, experienced a significant flood in early January 2021. The rainfall intensity during this event reached approximately 282.6 mm/hour, the highest recorded since 2011. This flood caused extensive damage to several facilities and residential areas. The impact of such disasters can be mitigated through identification, evaluation, and preventive measures. One such preventive approach is flood identification, which involves mapping flood extent areas. This study utilized Google Earth Engine (GEE), a web-based application platform, to achieve this. The advanced capabilities of GEE enabled the identification of flood distribution in January 2021. The results revealed that the cumulative flood distribution area was 37.89 hectares on January 2 and 149.88 hectares on January 10, with the largest affected area in Tanjungpinang Timur, covering 89.858 hectares. Based on the disaster risk level guidelines outlined in Regulation Number 02/2012, issued by BNPB, the floods on January 2 and 10, 2021, were classified as ‘High-Level’ disasters.
