Abstract

The frequent landslides in Nagari Malampah are caused by the location of the area near an active fault zone and the effects of the 2022 earthquake centered in Pasaman Barat Regency. The study aims to identify subsurface layer structures related to landslide susceptibility using the seismic refraction method. Field data were acquired along three survey line and processed using the Time-Term Inversion method. The results indicate the presence of two main subsurface layers. The first layer exhibits P-wave velocities ranging from 277.45 to 581.85 m/s at depths of approximately 3-6 m, interpreted as unconsolidated alluvial deposits consisting of sand, slit, and clay. The second layer shows higher velocities ranging from 499.49 to 1093.12 m/s at depths of 12-32 m, suggesting denser materials such as compact clay, dense sand, and weathered bedrock. The significant velocity contrast between these layers indicates the presence of potential weak zones that may act as slip surfaces under conditions of high rainfall and seismic activity. These findings provide important information for landslide hazard assessment and mitigation planning in Nagari Malampah.

Abstract

Landslides are the downward movement of masses of soil and rock caused by slope instability. The instability develops when the balance of forces acting on the slope is disturbed. Mandeh area is one of the areas frequently affected by landslides. Based on these issues, mitigation efforts are needed to minimize losses due to landslides, which can be identified using the Microtremor method based on dominant frequency, amplification, and the seismic susceptibility index. The collected microtremor data were processed using the Horizontal to Vertical Spectral Ratio (HVSR) method to obtain dominant frequency, amplification factor, shear wave velocity, and seismic vulnerability index values, which were then used to assess landslide susceptibility in the study area, with data collection conducted directly in the study area. Landslide-prone areas in the Mandeh area, Koto XI Tarusan District, were identified as areas with dominant frequencies of 0.1 Hz – 3.85 Hz, amplification factors of 3.41, 3.67, 4.78 and 5.331, shear wave velocities of 120 m/s – 170 m/s, and seismic vulnerability indexes of 3.17537–5.456896. The areas that meet these criteria are located at research points TP2, TP7, T11 and TP14.

Abstract

This study examines research trends in IoT-integrated automated titration systems employing peristaltic pumps through a combined bibliometric analysis and Systematic Literature Review (SLR). Data were collected from the Scopus and Google Scholar database covering the period 2016-2026 and analyzed using VOSviewer to map publication trends, geographical distribution, journal contributions, and keyword co-occurrence networks. The result reveal a fluctuating yet overall increasing research trend, with peak publication activity observed 2019 and 2021. The united States and Brazil dominant research output, followed by emerging contributions from China, India, and Indonesia. Journal distribution indicates that publications are concentrated in a limited number of core outlets, particularly within analytical chemistry and chemical education. Keyword analysis identifies major themes such as titration, automatic titration, peristaltic pump, arduino, and Internet of Thigs, indicating a convergence between analytical chemistry and digital technologies. This study provides a comprehensive overview of the field, identifies research gaps, and offers insight for future developments of intelligent, IoT-based laboratory systems.
