Abstract

Padang City, situated in a seismically active region, faces significant earthquake risk due to its complex geological structure. This study integrates passive seismic and geoelectrical resistivity methods to characterize subsurface conditions and map seismic vulnerability across 11 districts. Passive seismic data, collected from 84 microtremor stations, were analyzed using the Horizontal-to-Vertical Spectral Ratio (HVSR) method to derive dominant frequency (f?), amplification factor (A?), and seismic vulnerability index (Kg). High Kg values, indicating elevated seismic amplification potential, were observed in Koto Tangah, Kuranji, and parts of South and West Padang. Subsequently, geoelectrical surveys along five targeted lines revealed subsurface heterogeneities, including groundwater-saturated layers and weak sediment zones that heighten liquefaction risk. The integration of HVSR and resistivity data provided a robust framework for identifying high-risk areas with greater precision than single-method approaches. These findings offer critical input for seismic microzonation and urban disaster mitigation planning, underscoring the need for multi-method geophysical assessments in earthquake-prone urban settings.

Abstract

This study looks into the thermal risks and ways to deal with them that come with coal self-combustion at the Alam Barajo stockpile, which is run by PT. Kuansing Inti Makmur. Three coal piles: UHS 12F (±2 months), UHS 01A (±1 month), and Medium 11C (±3 months), were monitored to see how the length of time they were stored and how often it rained affected the temperature rise and the subsequent quality loss. The results reveal that the temperature of the pile rises dramatically with extended storage. For example, UHS 12F had a daily rise of 5.04°C, while UHS 01A saw a rise of 1.65°C. Self-combustion in Medium 11C reached a high of 222.1°C, which caused the ash content to rise by 2.62% and the calorific value to drop. Heavy rain made the temperatures drop for a short time, which suggests that evaporative processes caused the cooling. The study shows that present ways of managing stockpiles, especially the FIFO technique, are not being used to their full potential. To reduce the risk of combustion and keep the quality of the coal, engineers advocate making changes like regular temperature monitoring, correct compaction, covering with tarps, and distributing the coal before it catches fire.

Abstract

Kenagarian Jopang Manganti merupakan salah satu Nagari yang terletak di Kecamatan Mungka Kabupaten 50 Kota Sumatera Barat. Sekitar 10 tahun yang lalu aktivitas masyarakat kebanyakan bertani padi. Akan tetapi keadaan ini berubah semenjak harga cabe melonjak tinggi apalagi menjelang bulan puasa dan hari raya Idul Fitri. Banyak masyarakat yang mengubah sawah mereka menjadi ladang cabe. Terdapat puluhan KK yang menggeluti usaha ini dan menggantungkan hidup dari bertani cabe. Meningkatnya harga cabe di pasaran tidak sepenuhnya dirasakan efeknya oleh petani cabe. Keterbatasan akses dan informasi membuat petani cabe menjual hasil ladangnya biasanya ke toke dengan harga rendah. Apalagi hasil yang dijual masih dalam keadaan asli dari ladang. Padahal apabila cabe dilakukan pengolahan, akan menghasilkan produk yang memiliki nilai jual yang lebih tinggi. Dalam kegiatan pengabdian kepada masyarakat ini akan dilakukan upaya untuk meningkatkan nilai jual cabe dengan beberapa hasil produk olahan. Metode yang yang dilakukan dengan memberikan bimbingan teknologi, pendampingan, dan penguatan proses produksi seperti pengemasan dan proses penjualan. Hasil yang didapatkan berupa kepuasan masyarakat dalam pemahaman budidaya cabe secara menyeluruh dan meningkatnya produksi cabe yang bisa dihasilkan mencapai 40 kg dalam satu jam.

Abstract

Kesadaran masyarakat memanfaatkan sampah menjadi sesuatu yang tidak ekonomis menjadi ekonomis sangatlah kurang. Oleh karena itu, maka diberikanlah pelatihan kepada ibu-ibu rumah tangga dan remaja putri di RT 02/04 dan RT 04/Rw 04 Kelurahan Batang Arau Padang agar dapat mengolah sampah organik menjadi sesuatu yang mempunyai nilai jual tinggi. Solusi untuk menyelesaikan permasalahan ini adalah dengan membuat Reaktor Biokompos Hi. Hasil dari Reaktor Biokompos Hi adalah pupuk organik cair, larva lalat BSF dan kompos. Ketiga hasil dari Reaktor Biokompos Hi sangat mempunyai daya jual yang tinggi. Misal pupuk organik cair dapat dijual sebagai pupuk tanaman, larva Black Soldier Fly BSF dapat dijual untuk pakan ikan atau burung, sedangkan kompos padatan dari sisa sampah organik bisa digunakan untuk sarana temapt berkembang biaknya cacing tanah. Kegiatan PKM ini dilaksanakan pada tanggal 14 Oktober 2021 yang dihadiri oleh 20 ibu-ibu rumah tangga dan remaja putri. Kegiatan ini dilakukan dengan metode penyuluhan dan praktek.

Abstract

Indonesia is a country rich in tin minerals. Indonesia has 17% of the world's total tin reserves but produces 26% in 2020. This shows an unequal value between income and expenditure. Therefore it is necessary to calculate tin resources on a regular basis so that their availability is maintained. Here, two methods of calculating the estimated tin resources are used, namely the inverse distance weighted (IDW) and nearest neighbor point (NNP) methods. The estimation results using both methods are tin resources using the IDW method of 1,501,300 tons while using the NNP method 1,270,222 tons. In conclusion, there is a difference in the estimation results using the two methods of 231,078 tons or 18%. This difference is caused by the working of the two methods, namely the principle IDW method considers several closest points, while the NNP method considers the closest point.

Abstract

Coal is one of the fuels sourced from solid hydrocarbons. Bataubara itself is formed from plants and microorganism that solidifies due to the influence of pressure. The use of coal as a fuel is widely used in large industries, such as the cement industry and in steam power plants. administratively the mining concession of PT. Bukit Asam, Tbk. is included in the Tanjung Enim City, South Sumatra Province. In July 2022, there was a torn Coal Conveyor-07 (CC-07) incident that disrupted productivity at TLS 2 (Train Loading Station) so that it could not deliver coal, causing losses to the company with a total of 42,562 tons. With a total loss of Rp. 28,372,329,681.
