Abstract

The development of information technology has encouraged organizations to improve information management. However, the Association of Indonesian Academics and Scientists (ASASI) West Nusa Tenggara does not yet have an integrated web-based system for managing and presenting management member profiles. As a result, profile information is scattered, lacks structure, and is difficult for both internal members and the public to access. Additionally, management members have limited ability to independently manage and update their profile data. This study aims to design and implement an HTML-based frontend for a management member profiling system that enables both visualization and self-management of profile data. The system is developed using HTML, CSS, and PHP native without frontend frameworks or RESTful APIs to ensure simplicity, ease of maintenance, and suitability to organizational needs. The effectiveness of this approach is evaluated using usability, accessibility, and maintainability indicators, including ease of navigation, clarity of information presentation, and minimal dependency on external frameworks. The results show that the system successfully provides structured and user-friendly profile information while enabling efficient data management by users. The system improves transparency, enhances information dissemination, and supports more effective organizational management in the digital era.

Abstract

Landslides are a persistent geological hazard, especially in seismically active and high-rainfall regions such us Lombok Island, Indonesia. This study addresses landslide susceptibility in Sembalun Bumbung Village, located within the Rinjani Area, by integrating ground displacement monitoring with multi-parameter spatial analysis. Advanced image processing techniques were applied to Sentinel-1A Interferometric Synthetic Aperture Radar (InSAR) data, specifically processed using Differential Interferometric Synthetic Aperture Radar (DInSAR) technique, to observe and quantify annual ground displacement from 2019 to 2024. Simultaneously, a landslide susceptibility map was developed through the analysis of five key environmental parameters: rainfall, rock type, slope gradient, land cover, and soil type; each weighted and scored based on their empirical contributions to landslide risk. The DInSAR analysis revealed annual ground displacement values ranging from 0.030 to 0.105 meters, with the highest rates detected at points T6 and T7 in Benyer Hamlet. The resulting landslide susceptibility map categorized areas into five susceptibility levels (very low, low, moderate, high, and very high). Notably, points exhibiting a very high susceptibility (e.g., T1 in Bebante Daya Hamlet, T2 in Jorong Utara Hamlet, as well as T6 and T7 in Benyer Hamlet) consistently correlated with the highest annual displacement values observed from the DInSAR analysis. This integrated approach offers a solid basis for targeted mitigation strategies, including enhanced monitoring, risk communication, land-use planning, and potential early warning systems.

Abstract

Indonesia’s tectonic setting makes coastal areas highly vulnerable to seismic hazards, including liquefaction. This study aims to analyze the liquefaction potential in Arang Beach, Labuhan Ijuk, Sumbawa, using the Horizontal to Vertical Spectral Ratio (HVSR) method. Microtremor data were collected at 70 measurement points and processed using Geopsy through windowing, filtering, and HVSR analysis to obtain dominant frequency (f₀) and amplification factor (A₀), followed by inversion to estimate shear wave velocity (Vₛ), sediment thickness (h), and Poisson’s ratio (σ). The results show that f₀ ranges from 0.294–17.542 Hz and A₀ from 0.928–15.914, with low-frequency and high-amplification zones concentrated in the southern–western area, indicating thick, soft sediments. Vₛ values (63.486–712.48 m/s) further confirm the presence of very soft to hard subsurface layers, with high liquefaction susceptibility associated with low Vₛ, high σ, and thick sediments. These findings indicate that the southern–western part of the study area has the highest seismic vulnerability and liquefaction potential. This study concludes that HVSR is effective for identifying site effects and liquefaction-prone zones. The results provide a scientific basis for seismic microzonation, coastal spatial planning, and the development of earthquake-resistant infrastructure in vulnerable coastal regions.
