Abstract The island of Lombok in Indonesia is located between the Indo-Australian and Eurasian subduction trenches Flores back-arc thrust, making it vulnerable to earthquakes. On 29 July 2018, a significant earthquake Mw 6.4 shook this region was followed by series major earthquakes (Mw>5.8) on 5, 9, 19 August, which led severe damage northern area. In study, we attempt reveal possible cause sequences 2018 based aftershock monitoring data. Twenty stations were deployed record waveform...
Pulau Lombok memiliki beberapa kawasan yang berpotensi terjadi bencana longsor karena kemiringan lereng curam (> 25%) dengan jenis tanah dominan adalah andosol sifat peka erosi dan curah hujan lebih dari 1000 mm. Sepanjang tahun 2023 BPBD Provinsi NTB mencatat 22 kejadian longsor. Dengan adanya kondisi tersebut maka dibutuhkan penelitian pemetaan daerah rawan sebagai upaya mitigasi bencana. Pemetaan menggunakan parameter yaitu lereng, hujan, tata guna lahan, geologi, kedalaman solum,...
We have successfully conducted the first ambient noise tomography on island of Lombok, Indonesia using local waveform data observed at 20 temporary stations. Ambient was used to delineate seismic velocity structure in upper crust. The were recorded from August 3rd September 9th, 2018, short-period and broadband sensors. There are 185 Rayleigh waves retrieved cross-correlating vertical components seismograms. frequency-time analysis (FTAN) acquire interstation group dispersion curves. Group...
Local earthquake data was used to determine a three-dimensional (3D) seismic attenuation structure around the aftershock source region of 2018 Lombok in Indonesia. The aftershocks were recorded by 13 stations from August 4 September 9, 2018. selected consist 6,281 P-wave t ∗ values 914 events, which had good quality at least four stations. Our results show that two clusters northwest and northeast Island have different characteristics. A low factor (low- Qp) , velocity ( Vp) high ratio...
Because of its robustness and practicality, the Horizontal-to-Vertical Spectral Ratio (HVSR) method has been widely used to obtain subsurface structure, mainly sediment thickness that resides over bedrock. The uses Fourier Transform frequency spectrum calculate H/V ratio. However, conventional some limitations; e.g., inability remove local noises are very common in microtremor recordings. In this study, we investigate a relatively new technique, Hilbert-Huang Transform, obtaining HVSR curve,...
Abstract Lombok is one of the islands in transitional zone from Sunda Arc to Banda Arc, Indonesia. In mid-2018, island was shaken by a series strong earthquakes, started with moment magnitude (M w ) 6.4 earthquake on July 29, 2018 followed earthquakes August 5 7.0), 9 5.9), and 19 6.3 6.9). Some researchers suggested that this phenomenon occurred due segmentation rupture northern part Island. This study aims obtain information distribution fault also understand character seismic anisotropy...
The use of natural enemies as pest control has long been known, but largely replaced by the rapid development chemical pesticide industry technology, especially since green revolution. One alternative technology that is quite promising to be developed biological agents (predators or parasotoids) have more characteristics than characteristics. With presence which are then used suppress populations, it will safe for human health and environment. It can hoped agricultural products produced...
Bencana tanah longsor merupakan bencana yang selalu terjadi di beberapa wilayah Kabupaten Lombok Utara. Sepanjang tahun 2022 BPBD Provinsi NTB mencatat 22 kejadian mengakibatkan terjadinya korban jiwa dan kerugian materiil akibat kerusakan sarana prasarana umum Jumlah warga terdampak Utara tercatat sebanyak 353 KK atau 1.088 jiwa, salah satunya Desa Pemenang Barat tersebar Dusun Bentek, dusun Mekarsari, Telaga Wareng Pengempus. dapat disebabkan oleh kondisi geomorfologi seperti bentuk lahan,...
This research aims to identify the class of terpenoid compounds contained in hexane extract tobacco stems (Nicotiana tabacum). The extraction method uses solvent obtain bark. Gas chromatography-mass (GC-MS) techniques were used analyze and these compounds. compound Virginia stem bark is only one derivative, namely 4,8,13-Cyclotetradecatriene-1,3-diol. Analysis structure this shows its potential as an antimicrobial can be applied agricultural industry, a botanical pesticide. Its unique...
To anticipate the potential trends of traffic problems in future, a series management and engineering efforts need to be carried out on roads Sumbawa Regency (Sumbawa Besar). This study aims obtain road segments implement engineering. The was conducted six using inventory surveys Traffic Counting (TC), as well 21 intersections Classified Turning Moving (CTMC), which were then analyzed PTV Vissim application. Based analysis, results indicate that signal cycle change scenario can improve level...

Sustainable Development Goals (SDGs) in protecting marine and coastal ecosystems reducing the risk of natural disasters can be achieved through mangrove planting activities at Cemara Beach. Mangroves are useful maintaining ecosystem balance, coastline from abrasion absorbing carbon dioxide which reduce impact climate change. Mangrove involve local communities maintenance process, contribute to improving community welfare environmentally-based economic development. use seedlings aged 3 6...

 In 2018, Lombok Island was hit by a series of destructive earthquakes. According to Indonesian Meteo- rological, Climatological, and Geophysical Agency data, about 1,973 felt earthquakes (M > 3) which shaken were recorded during August 2018 with three the largest magnitude 6.9 Mw, 6.8 6.2 Mw. National Board for Disaster Management reported 555 deaths, 1,833 people injured, 186,010 houses damaged as result earthquake on 5th, 2018. A number seismometers placed from 3rd, October 19th,...
Abstract: Currently the safety level in province of NTB is above national average rate, this indicated by accident fatality ratio per 100,000 which 11.07 while rate 10.47, figure must continue to reduce risk factors for accidents. Based on NTB, 2017 figures show that 2016 largest number perpetrators were at Junior High School (SMP) level, namely 38%. Seeing data, it necessary increase public awareness importance and how maintain driving. One efforts can be done socializing driving safety....
Abstract Shear-wave splitting (SWS), or the propagation of two independent shear waves, can be used as an indicator seismic anisotropy. In this study, we utilize concept using aftershock data 2018 Lombok earthquake which had been acquired in period August 4 – September 9, 2018. The goal research is to better understand crack distribution related rupture zone earthquake. After applying instrument correction data, waveform were then windowed each P and S arrival time. To determine SWS...
Geofisika merupakan studi yang mengkaji kondisi bawah permukaan Bumi berdasarkan parameter fisiknya. Komponen penyusun masing-masing memiliki ciri fisik unik misalnya: kerapatan, kecepatan rambat, konduktivitas listrik, suseptibilitas magnetik, dan konstanta dielektrik dari tiap jenis batuan akan berbeda.
