Abstract

The fulfillment of clean water needs in Sengkubang Village is done by utilizing groundwater, which in some locations still has a brackish to salty. This situation is one indication of seawater intrusion into groundwater because Sengkubang Village is a coastal area. This study aims to estimate the distribution of seawater intrusion based on the subsurface resistivity value. The method used is the resistivity method with dipole-dipole configuration. Measurements in the field apply six lines with a length of 55 m and the smallest electrode distance of 5 m. The distance of each line from the coastline is approximately 410 m, 485 m, 560 m, 635 m, 710 m, and 785 m. The interpretation results show that the seawater intrusion at the study area has a resistivity value of 0.223 Ωm - 5.03 Ωm at a depth of 0.854 m to 10.9 m. The subsurface layer at the study site is composed of sand, sandy clay, and gravel sand mixed with silt. The unconfined aquifer layer, which is interpreted as sand, is thought to have experienced seawater intrusion to 785 m from the coastline.

Abstract

Perairan pesisir pantai Gosong merupakan salah satu perairan yang dimanfaatkan berbagai macam aktivitas diantaranya adalah sebagai pelabuhan perikanan, keluar masuknya kapal dan termasuk kawasan strategis dalam pengembangan kawasan pesisir. Aktivitas tersebut akan berdampak kepada proses pengendapan sedimen dasar yang mengakibatkan terjadinya pendangkalan, perubahan garis pantai dan penurunan kualitas air. Tujuan penelitian ini adalah untuk mengetahui sebaran dan jenis sedimen dasar berdasarkan analisis parameter statistik ukuran butir. Metode yang digunakan dalam penelitian ini adalah metode granulometri sedimen dan pendekatan statistik ukuran butir. Pengambilan sampel sedimen dan kecepatan arus dilakukan masing – masing sebanyak 10 titik stasiun. Sedangkan pengukuran pasang surut dilakukan selama 15 hari dengan interval waktu setiap 1 jam. Berdasarkan analisis granulometri diperoleh bahwa sebaran sedimen yang mendominasi di lokasi ini adalah lanau dengan tipe sedimen lempung berlumpur (silty clay). Hasil analisis ukuran butir dengan pendekatan statistik diperoleh nilai ukuran butir rata – rata 1,31 – 2,96 dengan klasifikasi pasir halus (fine sand) dan pasir sedang (medium sand). Untuk nilai sortasi terdapat tiga stasiun yang mempunyai klasifikasi terpilah sedang yaitu pada Stasiun 3, 6 dan 8, sedangkan pada stasiun lainnya didominasi pada klasifikasi terpilah buruk. Nilai skewness secara umum menunjukkan klasifikasi ukuran butir sedimen condong sangat halus (very fine skewed) dengan rentang nilai berkisar antara 0,63 – 2,04. Sedangkan nilai kurtosis diperoleh tiga klasifikasi ukuran butir sedimen yaitu tumpul (platycuric), cukup tumpul (mesokurtic) dan runcing (leptokurtic). Nilai kurtosis yang diperoleh memperlihatkan bahwa semakin dalam nilai kurtosis yang dihasilkan semakin kecil yaitu pada kedalaman 4,9 m nilai kurtosisnya 0,737 dan pada kedalaman 1,1 m nilai kurtosisnya 1,417.

Abstract

This research aims to estimate saltwater distribution around the  of Manis Raya Village, Sintang Regency. This research uses the self-potential method by a fixed base configuration. Measurements in the field applied eight tracks that have a length of 120 m each with a distance of 5 m for each track and 5 m for each porous spot. The distribution of saltwater around the brine well was obtained by interpolation using the kriging method. The measurement results show that the self-potential at the research location is -99.38 mV to 158.32 mV. The interpretation results show that the area of accumulated saltwater distribution is negative, located on the east, southeast, south and west sides of the . The low self-potential of saltwater is likely due to the accumulation of ions in the area. The saltwater distribution zone is suspected to be about 48 m to the southeast of the brine well.

Abstract

The urban heat island (UHI) phenomenon can cause the land surface temperature (LST) in the city center to be higher than in the surrounding area. The population of Pontianak City increases yearly, resulting in land cover changes and LST distribution. This research aims to monitor the UHI phenomenon by identifying the temporal distribution of LST in Pontianak City. This research analyses the Landsat 8 thermal band, which is converted into LST value based on the normalised difference vegetation index (NDVI). The land cover classification was conducted using a random forest algorithm and acquisition of confusion matrix classification accuracy value. This research utilizes the Google Earth Engine (GEE) platform because of its ability to process satellite data continuously and has data with a sizeable spatiotemporal dimension. The results show a strong relationship between urban development and LST distribution. Based on the land cover classification in 2014 and 2019, there is a significant change in the composition of the surface, namely, built-up land has increased, while open space and vegetation land have decreased. Time series analysis also shows that the average LST of built-up land, open space, and vegetation are 28.10℃, 22.80℃, and 21.56℃, respectively. The results of monitoring the UHI phenomenon can help in better urban spatial planning, especially in increasing green space, because it is proven effective in reducing land surface temperature.

Abstract

Sanggau Regency is a highland area that has a rough topography with a relief of undulating hills, causing the potential for landslides. One of the steps to reduce the impact of landslides is to identify the characteristics of landslide-prone areas by conducting magnetic susceptibility analysis in landslide-prone areas. This analysis is a method to identify landslide indicators based on their magnetic properties. This method identifies landslide potential through superparamagnetic grains on the surface soil. The presence of the grain can be known from the frequency-dependent susceptibility . The study was conducted on 40 soil samples taken at a 20-30 cm depth at Jalan Sabang Merah, Sanggau Regency. The results showed that the average values of low-frequency  and high-frequency  were 5.555 cm3/g and 5.478 cm3/g, respectively. A total of 36 soil samples have a  percentage of 0% (containing less than 10% superparamagnetic grains), two soil samples have a  percentage of 3.51% and 6.45%, respectively (containing 10%-75% superparamagnetic grains, and two samples have a  percentage of 10.48%-12.63% (containing more than 75% superparamagnetic grains). The interpretation results show that soil samples with more than 75% superparamagnetic grains indicate landslide-prone areas in the study site; thus, the areas suspected to have a high level of vulnerability are in the northeastern and southwestern parts of the study site.

Abstract

Tulungagung and Trenggalek are two regencies located south of Java Island with quite complex geological conditions because they are located in the Southern Mountains area. This study aims to identify the presence of faults based on the magnetic anomaly value of the Tulungagung sheet. The presence of faults at the research site were determined based on three lines on the regional magnetic anomaly using First Horizontal Derivative (FHD) and Second Vertical Derivative (SVD) derivative analyses. The results show that the regional magnetic anomaly is -210.7 nT to 113.2 nT. Line A-A' identified two fault locations at a distance of 15 km and 27 km from the line's starting point. Line B-B' identified three fault locations at a distance of 4 km, 27 km, and 45 km from the line's starting point. Line C-C' identified three fault locations at 10 km, 22 km, and 42 km from the line's starting point. The interpretation results also obtained subsurface lithology in the Alluvium Formation, Arjosari-Mandalika Formation, Wungkal Limestone Formation, and Malihan Rock Formation.
