Abstract

The level of damage caused by an earthquake is related to the physical parameters obtained from Horizontal-to-Vertical Spectral Ratio (HVSR) analysis. The dominant frequency (f0) and wave velocity are the two HVSR parameters used. This research aims to determine the type of rock and the level of damage to buildings caused by the 2018 Lombok earthquake. We used secondary data from the 2011 Mataram City microtremor, which included 85 measurement points. We conducted frequency spectrum analysis using the HVSR method and shear wave velocity (vs) inversion modeling to gain a comprehensive understanding of Mataram City seismic properties. The Poisson ratio analysis results reveal that earthquake-prone sedimentary layers dominate Mataram City. The HVSR analysis revealed a negative correlation between the damage from the 2018 earthquake and the dominant frequency and shear wave velocity. The overlay results between the dominant frequency values, shear wave velocity, and the comparison of vp and vs with the damage level from the 2018 earthquake demonstrate this.

Abstract

Research on site vulnerability identification using the Refraction Microtremor (ReMi) method has been conducted in Sambelia District, East Lombok regency. The purpose of this study was to identify the vulnerability of the soil in the study area by determining the lithology of subsurface rocks. Measurement of Microtremor Refraction (ReMi) was carried out at 16 points spread over the study area. Data processing to obtain 1D shear wave velocity profile using McSEIS seisimager surface wave analysis wizard. Based on the research that has been done, four layers of rock are obtained, namely the first layer with a value of Vs 466-543 m/s in the form of clay at a depth of (0-6.0 m), the second layer with a value of Vs 429-668 m/s in the form of solid sand and gravel at a depth of (6.0-16.1 m), the third layer with a value of Vs 726-812 m/s in the form of breccia at a depth of (16.1 - 18.6 m), and the fourth layer with a value of Vs 905-1454 m/s identified as the Tuff is at a depth of (18.6 – 30.0 m). The conclusion of this study is that Belanting and Sugian villages have a high level of vulnerability because they are dominated by very dense soils and soft rocks (Type C) with constituent rocks, namely alluvial rocks (solid sand, gravel, clay, and silt) and Darakunci village has a low level of vulnerability composed of breccia and Tuff rocks.

Abstract

Montong Ajan Village is one of the areas in East Lombok Regency that has a high level of vulnerability to earthquakes and tsunamis, considering its location close to the Sumba Megathrust zone. The lack of disaster literacy among the community, especially elementary school children, is a major challenge in disaster mitigation efforts. This community service activity aims to improve disaster mitigation knowledge and skills through an educational and participatory approach. The activity was carried out at Aik Belek State Elementary School (SDN), with methods that included delivering visual materials, group discussions, earthquake evacuation simulations, introducing local risk maps, and practicing preparing disaster preparedness bags. The results of the activity showed an increase in participants' understanding of emergency response steps and high enthusiasm in participating in the simulation. In addition, teachers and schools showed a commitment to integrating disaster education into thematic learning activities. This activity is expected to be the first step towards the formation of a resilient community that is able to respond to disasters quickly, appropriately, and independently.

Abstract

Indonesia has a high level of geological disaster threat due to its location at the meeting point of three tectonic plates, making coastal areas, such as Lombok Island, very vulnerable to earthquakes and tsunamis. Although Lombok has a history of earthquakes (2018) and tsunamis (1977), initial observations in Torok Aik Belek Hamlet, South Lombok, show that community awareness and preparedness for disaster mitigation are still low, exacerbated by unverified information on social media and the perception of underestimating potential hazards. This study aims to conduct participatory earthquake and tsunami risk mapping in Torok Aik Belek Hamlet and develop community-based mitigation strategies. The implementation methods include initial assessment, coordination with BMKG, presentation of materials, interactive counseling, and community empowerment as a disaster preparedness team. The results of the activities show clear identification of disaster-prone locations (for example, residential areas near the coast and concrete buildings) and vulnerable groups. Utilization of local potential, such as hills as evacuation routes and disaster-resilient village status, is the basis for developing disaster mitigation strategies. The formation of a local community in Torok Aik Belek Hamlet involving residents and members of the Disaster Resilient Village is a crucial step. It is hoped that this effort can significantly increase the preparedness of the Torok Aik Belek Hamlet community and contribute to an adaptive and sustainable community-based mitigation development model.

Abstract

Magnetite (Fe3O4) is a spinel-based material that has broad potential in various applications, one of which is for magneto-optics. However, the value of the energy gap obtained from magnetite is too small to be applied. Efforts to improve these characteristics are carried out through transition metal ion doping techniques, one of which is cobalt (Co2+) which is known to modify the electronic structure and stabilize the crystal lattice. This study aims to analyze the optical properties of magnetite nanoparticles that have been doped with Co2+ through energy gap and Urbach energy calculations. The synthesis of Co0.125Fe2.875O4 was carried out using the coprecipitation method. Furthermore, characterization was carried out using UV–Vis spectroscopy and analyzed the size of the energy gap and Urbach energy. The results showed that cobalt doping (Co0.125Fe2.875O4) produced two indirect energy gap values ​​of 2.07 eV and 3.19 eV and one direct energy gap value of 3.63 eV. Urbach energy analysis revealed a very low Eu value of 0.0073 eV, indicating high crystal regularity and minimal structural defects in the material. This study demonstrated that cobalt doping not only increases the band gap energy of magnetite but also significantly lowers the Urbach energy, resulting in a material with more pronounced optical properties.

Abstract

Batik is an Indonesian cultural heritage that embodies deep philosophical values and national identity. However, traditional batik-making techniques are often considered complex for beginners since they require specific skills. Therefore, the tie-dye technique, also known as batik ikat celup, is introduced as a simpler and more accessible alternative that can serve both as a learning medium and as an entrepreneurial opportunity. This community service program was conducted at Pondok Pesantren Al-Intishor, Mataram, involving 9th and 10th grade students. The method included delivering introductory materials, demonstrations, and hands-on practice in small groups under intensive guidance. The results revealed high enthusiasm among both students and teachers, who acknowledged the relevance of this activity to be integrated into craft and entrepreneurship education. Students successfully understood the stages of tie-dye batik making—from material preparation to the drying process—while also developing creativity through unique motifs and color variations. This program proved effective not only in enhancing knowledge about batik but also in fostering practical skills, self-confidence, and basic entrepreneurial potential. Thus, tie-dye batik training can be regarded as a strategic medium to preserve cultural heritage while simultaneously improving participants’ economic independence.
