Abstract

Geophysical engineering and civil engineering are related fields that are essential to the planning, building, and sustainability of infrastructure projects. Geophysical methods provide essential insights into subsurface conditions, enabling civil engineers to optimize infrastructure design, ensure long-term safety, and mitigate risks. The integration of geophysical techniques into civil engineering has transformed project workflows by offering non-invasive solutions for subsurface investigations, reducing the reliance on intrusive methods such as drilling and others that are disruptive to the environment. These methods are particularly valuable in high-cost infrastructure projects, such as bridges, tunnels, and dams, where understanding the subsurface is crucial for structural integrity. This study, based on a comprehensive literature review, analyzes the capabilities and applications of geophysical methods, including ground penetration radar, seismic method, and electrical resistivity in civil infrastructure projects. This study outlines the current state of knowledge and identifies potential to improve the use of geophysical techniques in civil infrastructure projects by combining findings from prior research.

Abstract

Bencana tanah longsor merupakan bencana yang selalu terjadi di beberapa wilayah di Kabupaten Lombok Utara. Sepanjang tahun 2022 BPBD Provinsi NTB mencatat 22 kejadian bencana longsor yang mengakibatkan terjadinya korban jiwa dan kerugian materiil akibat kerusakan sarana dan prasarana umum Jumlah warga terdampak bencana longsor tahun 2022 di Lombok Utara tercatat sebanyak 353 KK atau 1.088 jiwa, dan salah satunya di Desa Pemenang Barat yang tersebar di Dusun Bentek, dusun Mekarsari, Dusun Telaga Wareng dan Dusun Pengempus. Bencana longsor dapat disebabkan oleh kondisi geomorfologi seperti bentuk lahan, kelerengan, jenis batuan, proses pelapukan, bidang-bidang diskontinuitas, curah hujan yang tinggi, penggunaan lahan, kondisi hidrologi dan vegetasi. Mitigasi bencana terdiri dari mitigasi struktural longsor, yaitu pembangunan dinding penahan yang di buat menggunakan sistem drainase dan pembangunan terasering menggunakan penguatan bronjong. Mitigasi non-struktural, yaitu pemasangan sistem peringatan dini, terdapat jalur dan tanda arah jalur evakuasi, sosialisasi tentang bencana longsor, dan pembuatan papan peringatan daerah rawan bencana longsor. Program pengabdian masyarakat ini bertujuan untuk meningkatkan pemberdayaan masyarakat dalam kegiatan mitiigasi bencana dengan pengetahuan dan pemahaman masyarakat tentang kegiatan mitigasi bencana longsor. Metode yang dilakukan adalah dengan pelatihan melalui ceramah dengan bantuan leaflet/brosur dan audio visual, diskusi dan tanya jawab serta praktek mitigasi bencana longsor, baik pra bencana, saat bencana maupun pasca bencana. Berdasarkan hasil kegiatan, maka peserta telah memahami manfaat dan cara melaksanakan kegiatan mitigasi bencana longsor. Selain itu, perlu adanya pemasangan tanda dan papan peringatan dan jalur evakuasi serta sistem peringatan dini atau EWS (Early Warning System) untuk monitoring di kawasan yang berpotensi dan rentan longsor sebagai antisipasi erjadinya korban jiwa dan materiil akibat bencana tanah longsor..

Abstract

Sustainable Development Goals (SDGs) in protecting marine and coastal ecosystems and reducing the risk of natural disasters can be achieved through mangrove planting activities at Cemara Beach. Mangroves are useful in maintaining ecosystem balance, protecting the coastline from abrasion and absorbing carbon dioxide which can reduce the impact of climate change. Mangrove planting activities involve local communities in the planting and maintenance process, and contribute to improving community welfare and environmentally-based economic development. Mangrove planting activities use seedlings aged 3 to 6 months. Mangrove planting is in a location with a water depth of 10 to 50 cm. The size of the mangrove seedlings planted is 15 to 30 cm. The type of mangrove planted at Cemara Beach is Rhizophora. Mangrove planting activities support SDGs 13, 14, dan 15 tentang climate action, life below water, and life on land.

Abstract

Tahap perkembangan remaja pada siswa SMA/SMK membawa pengaruh pada pengelolaan emosi yang berdampak terhadap perilaku berlalu lintas. Untuk meningkatkan kesadaran serta mengurangi resiko kecelakaan berlalu lintas pada usia remaja, diperlukan pendidikan keselamatan berlalu lintas berupa kegiatan sosialisasi keselamatan berlalu lintas. Kegiatan sosialisasi dilaksanakan di SMKN 1 Mataram dengan kondisi lalu lintasnya yang cukup padat. Kegiatan sosialisasi diawali dengan pretest untuk mengetahui tingkat pengetahuan siswa terhadap keselamatan berlalu lintas. Kemudian pemaparan materi yang disampaikan oleh Ditlantas Kepolisian Daerah Nusa Tenggara Barat, Dinas Perhubungan Provinsi Nusa Tenggara Barat dan dosen/civitas akademik Jurusan Teknik Sipil Fakultas Teknik Universitas Mataram. Setelah itu, dilanjutkan dengan sesi tanya jawab dan kuis untuk menguji serta memperdalam pengetahuan siswa terhadap topik yang disampaikan dengan cara yang interaktif. Kegiatan sosialisasi ditutup dengan penyerahan simbolis alat keselamatan jalan kepada Kepala SMKN 1 Mataram untuk demontrasi nyata penggunaan alat keselamatan jalan di lingkungan SMKN 1 Mataram. Hasil kegiatan ini menunjukkan bahwa para siswa telah mendapatkan pemahaman mengenai keselamatan berlalu lintas di jalan.

Abstract

This research aims to identify the class of terpenoid compounds contained in hexane extract of tobacco stems (Nicotiana tabacum). The extraction method uses hexane solvent to obtain terpenoid compounds contained in tobacco bark. Gas chromatography-mass (GC-MS) techniques were used to analyze and identify these compounds. The compound contained in the hexane extract of Virginia tobacco stem bark is only one terpenoid derivative, namely 4,8,13-Cyclotetradecatriene-1,3-diol. Analysis of the structure of this compound shows its potential as an antimicrobial and can be applied in the agricultural industry, namely as a botanical pesticide. Its unique chemical structure enables various mechanisms of action against microbes, which can be further explored for the development of agricultural applications. Further research is needed to fully understand the potential and mechanism of action of this compound in an antimicrobial context.
