Global warming caused by greenhouse gases is an issue that is a global problem. The construction sector is one of the main causes of the greenhouse gas effect. Green building is one of the buildings with a low level of carbon emissions. Approximately 87% of the total buildings in Indonesia are house. Green homes are houses that are built with the principles of sustainability and resource effici…
One of the factors that cause damage to road pavement is happening refined petroleum product spills from tank vehicles to road surface. Oil spills can also occur in at gas stations, petroleum refineries, and other industri es areas. Entry of refined petroleum products into the asphalt mixture can loss of adhesion between aggregate and asphalt causing reduced durability. These conditions encoura…
Secara umum, dalam perencanaan infrastruktur tahan gempa, terdapat beberapa jenis metoda analisis dengan tingkat kesulitan dan akurasi yang bervariasi. Sesuai dengan metoda analisis yang digunakan, parameter pergerakan tanah yang diperlukan untuk perhitungan dapat diwakili oleh percepatan tanah maksimum, respon spektra gempa, dan riwayat waktu percepatan gempa (time histories). Percepatan tanah…
Earthquake precursors using the earth's magnetic data by analyzing Ultra Low Frequency (ULF) emission anomalies is one of the earthquake disaster mitigation efforts. This study uses 11 earthquake data in the Province of West Sumatra and its surroundings in 2021 with coordinates (3.50ºLS-1.20ºN and 98.10º-102.10ºE). This study was conducted to determine Ultra Low Frequency (ULF) emission ano…

Panasbumi (geothermal) merupakan sumber energi panas yang terbentuk secara alami di bawah permukaan bumi akibat dari aktivitas magmatisme di dalam kerak bumi. Sumber energi tersebut berasal dari pemanasan batuan dan air. Metode yang dilakukan berupa Pengamatan atau observasi lapangan dengan cara analisa data geokimia disetiap sampel air panas serta pengamatan secara fisik, adapun pengamatan sec…
Sumatra is one of the islands in Indonesia that is affected by active tectonic activities, because it is controlled by the interaction between the Indo-Australian and Eurasian plates. The interaction between the two lithospheric plates resulted in the emergence of the Barisan Orogeny, where the basin area was uplifted and active faults were developed along the island. This study examines the ro…
