Abstract

Tidal floods in the Semidang Alas Maras coast often occur and disrupt community activities. The height and area affected by tidal flood run-up is not the same every time. This research are to identify the factors that influence tidal floods and determine the effect of seasonal changes on tidal flooding run-up along Semidang Alas Maras coast by utilising measurement technology using drones. The method in this research is direct measurements of tides, visual photos topographic using drones, and also secondary data including tidal data from TMD model, rainfall, and wind data during tidal flooding. Based on the results of the study, it was found that tidal flooding run-up along Semidang Alas Maras coast was influenced by tides, high rainfall and wind. The mixed tide type of Semidang Alas Maras is Mixed Tide Prevailing Semidiurnal with a Formzhal number of 0.76. The area affected by the tidal flood run-up for the criteria of no danger and less danger every season is the same. Meanwhile, the criteria for moderately dangerous, dangerous and very dangerous vary every season. The highest area value occurring in the western season, the criteria for moderately dangerous 20% with an area of 83.06 Ha, 21% hazard with an area of 85.78 Ha, and very dangerous 23% with area of 93.95 Ha

Abstract

The coastline is the boundary between the land surface and the sea surface that can change every year. Enggano Island is one of the areas experiencing very rapid coastal changes. This research aims to identify changes in the coastline of Enggano Island over the past 5 years and determine the maximum and minimum changes in abrasion and accretion. The data processing results show that over the past 5 years, the coastline in three villages on Enggano Island has changed overall, with abrasion of 91.01 meters and accretion of 348.08 meters. Due to the wave height on Enggano Island, these three villages have experienced sedimentation (land addition) and changes in the coastline caused by accretion being greater than abrasion. For instance, in 2020-2021, the sea wave height peaked, causing abrasion. However, the wave height continued to decrease in the following years, causing land erosion each year. From the explanation above, it can be concluded that Enggano Island is experiencing changes in its coastline, which are predominantly caused by accretion events.

Abstract

Regulations and laws in Indonesia strongly support learning using teaching aids. Teaching media or aids are essential in the process of knowledge transfer for students. Students will find it easier to understand the lesson material if assisted by teaching aids, even if they are in a simple form. Teachers can introduce teaching aids made from recycled waste materials. Therefore, the aim of this community service activity is to introduce the development of teaching materials made from waste materials. A community service activity utilizing waste materials (cardboard, sticks, etc.) as classroom learning media will be conducted at SDIT Nurul Fikri, Bengkulu City. The target audience for this community service activity is teachers and some students. The method used consists of theory and practice. The service team will train teachers and students to create science teaching aids, particularly on the themes of pressure and energy. As a result of this activity, several examples of science teaching aids made from waste materials were produced. These teaching aids will certainly help enhance students' understanding and create their own appeal toward science subjects.

Abstract

Increasingly extreme climate change has increased rainfall intensity and uncertainty of weather patterns in many parts of Indonesia, including Bengkulu City. This phenomenon affects rainfall patterns, the duration of the wet and dry seasons, and wind speed, all of which have an impact on various aspects of life. This study analyzes the effect of wind direction and speed on rainfall in Bengkulu City using the Schmidt-Fergusson, Wind Rose, and Multiple Linear Regression models, based on data from the Fatmawati Soekarno Bengkulu Meteorological Station in 2019-2023. The results of this study indicate that the dominant wind direction comes from the north, northeast, and southeast, with an average speed of 2.47 m/s, categorized as a weak wind according to the Beaufort scale. The highest annual rainfall was recorded in October 2022 at 600 mm. Based on the Schmidt-Fergusson classification, Bengkulu City is included in climate type A with a Q value = 0.1. Regression analysis shows that wind speed has a significant negative effect on rainfall indicating that wind speed has a negative effect, meaning that an increase in wind speed will cause a decrease in rainfall, while humidity has a positive effect, indicating that when air humidity increases, rainfall will also increase. The R² value of 32.7% indicates that the wind, temperature, pressure, and humidity variables explain some of the variation in rainfall. This finding emphasizes the importance of monitoring wind elements in the early warning system for extreme weather and supports hydrometeorological disaster risk mitigation planning in coastal areas vulnerable to climate change.

Abstract

Estuari merupakan daerah bagian hilir dari sungai yang berhubungan dengan laut. Estuari Sungai Air Pino mengalami perubahan bentuk akibat terjadinya pendangkalan di mulut estuari yang dipengaruhi gelombang laut Pantai Mengkudum. Tujuan penelitian ini untuk mengetahui pengaruh energi gelombang laut terhadap perubahan Estuari Muara Air Pino. Metode riset ini adalah pengukuran langsung di lapangan pada 3 titik pengukuran dengan menggunakan Tide Gauge dengan parameter yang ditinjau tinggi dan periode gelombang. Berdasarkan riset yang telah dilakukan diperoleh tinggi gelombang berkisar 0,02 m – 1,07 m dengan nilai gelombang signifikan 0,52 m dan tinggi gelombang signifikan peramalan 0,38 m, periode gelombang berkisar 3,01 s - 10,73 s dengan periode gelombang signifikan 6,9 s dan periode gelombang signifikan peramalan 2,40 s. Energi gelombang berkisar 0,501 J – 1573 J. Pendangkalan Estuari Sungai Air Pino diakibatkan karena energi gelombang yang mengaduk partikel sedimen secara beragsung angsur dalam waktu yang lama dan kemudian partikel sedimen tersebut akan terbawa arus dan mengendap ketika kecepatan arus semakin melemah, endapan sedimen tersebut kemudian membentuk daratan baru yang berdampak pada perubahan Estuari Sungai Air Pino.

Abstract

This study investigates the microclimatic variability and trends of air temperature across three meteorological stations—Fatmawati, Bengkulu, and Kepahiang—in Bengkulu Province, Indonesia. Using five years of daily data (June 2020 to May 2025), minimum (Tmin), maximum (Tmax), and average (Tavg) temperatures were analyzed to understand both spatial patterns and temporal changes in surface air temperature. One-way ANOVA was conducted to assess whether mean temperatures differed significantly across stations, followed by Tukey  post hoc test for pairwise comparisons. The analysis revealed a consistent and statistically significant difference in all temperature variables (p 0.05), particularly between the inland highland station (Kepahiang) and the two coastal stations. In addition, monthly averages of Tavg were analyzed using simple linear regression, with significance tested via regression-based ANOVA. All three stations exhibited statistically significant warming trends (p 0.005), with slopes ranging from +0.0152 to +0.0213 °C/month (~0.18–0.26 °C/year), despite relatively modest coefficients of determination (R² = 0.14–0.24). These results highlight a dual climatic dynamic in the region: strong seasonal and spatial variability, overlaid with emerging baseline warming. The study underscores the importance of localized climate analysis for adaptation planning, particularly in topographically diverse tropical regions facing increased exposure to climate variability and change.

Abstract

Mackerel fish are a high-value fishery commodity whose migration patterns are influenced by several oceanographic factors. This study aimed to identify the influence of seasonal fluctuations in oceanographic parameters on the migration of tenggiri fish during 2013-2023 in seven waters of Bengkulu. Oceanographic data were obtained from the Marine Copernicus. The data were obtained from the Multi-Observation Global Ocean 3D Temperature Salinity Height Geostrophic Current and MLD product for the period from 2013 to 2023, with a spatial resolution of 0.125°, while the catch data were obtained from the Bengkulu Province Marine and Fisheries Department. The data were processed spatially and temporally using GrADS, Panoply, and ArcGIS. The results of the study show that temperature, salinity, and currents tend to be stable throughout the year, whereas chlorophyll-a and wind experience significant seasonal fluctuations. In Kaur, Bengkulu City, and North Bengkulu regions, spikes in chlorophyll-a and wind intensity during the Australian Monsoon and Transition II were positively correlated with increased mackerel catch yields. Conversely, areas such as Seluma and Central Bengkulu did not show a clear relationship between oceanographic parameters and catch yield. These findings confirm that chlorophyll-a and wind play a greater role in mackerel migration than do temperature or salinity.

Abstract

Rainfall is a vital climate component and its variability in equatorial regions such as Indonesia. Bengkulu City, with its strategic geographical position on the edge of the Indian Ocean, is influenced by global and regional climate, as well as local conditions such as topography and sea surface temperature. Air humidity is known to be significantly correlated with extreme rainfall, while wind speed plays a role in air convergence and cloud formation. Therefore, this research tends to examine the air humidity, wind speed and sea surface temperature’s influence on rainfall in Bengkulu City. The method employed in this research is quantitative technique with multiple linear regression analysis using SPSS model. The data employed are monthly data of air humidity, wind speed, sea surface temperature, and rainfall from 2003 to 2023. As model validation before regression analysis, normality and multicollinearity tests were conducted. The analysis outcomes present that air humidity has a significant and positive partial effect on rainfall, which is consistent with its role in the condensation process and cloud formation. In contrast, wind speed and sea surface temperature show no significant partial influence on rainfall. However, simultaneously, these three independent variables (air humidity, wind speed and sea surface temperature) have a significant effect on rainfall. The regression model was able to explain about 63.8% of the variation in rainfall, confirming that air humidity is the main predictor of rainfall in the Bengkulu region.

Abstract

Pantai Lais mengalami perubahan garis pantai yang sangat cepat yang disebabkan abrasi dan sedimentasi. Penelitian ini bertujuan untuk mengidentifikasi karakteristik dinamika angin dan  Longshore  Current, dan pemetaan perubahan garis pantai di segmen Pantai Lais.  Penelitian ini merupakan penelitian kuantitatif-deskriptif. Subjek penelitian mencakup data oseanografi seperti kecepatan dan arah Longshore  Current, kecepatan angin, serta tinggi dan periode gelombang laut yang diperoleh melalui pengukuran langsung di lima titik pengamatan pada dua musim peralihan. Data yang sudah diperoleh kemudian dianalisis secara deskriptif dan kuantitatif. Temuan penelitian menunjukan perubahan garis pantai di segmen Lais sangat dipengaruhi oleh dinamika angin dan Longshore  Current, dimana angin adalah faktor utama pembangkit gelombang. Ketinggian gelombang laut akan menimbulkan gelombang pecah yang merupakan penyebab terbentuknya Longshore  Current. Ketinggian gelombang laut dan kuatnya energi gelombang menghantam dinding pantai, mengakibatkan pinggir pantai terabrasi. Material terabrasi ini akan ikut terbawa oleh Longshore  Current   sesuai dengan arah gerak arus mengalir, yang kemudian akan menumpuk di daerah yang kecepatan aliran arus lemah atau mengecil, sehingga terjadi sedimentasi. Rata-rata sedimentasi selama 10 tahun terakhir sebesar 10,60 meter/tahun, dengan sedimentasi tertinggi terjadi tahun 2017 sebesar 29,05. Sedangkan rata-rata abrasi selama 10 tahun terakhir 13,03 meter/tahun, dengan abrasi tertinggi tahun 2015 sebesar 20,5 m. Penelitian ini berimplikasi dalam perencanaan zona pesisir, terutama dalam mitigasi erosi pesisir, perencanaan ruang pesisir, dan perlindungan pemukiman serta infrastruktur yang rentan terhadap abrasi.
