Abstract

The outbreak of the Covid-19 pandemic to Indonesia, including the city of Padang, resulted in educational activities at Andalas University having to follow general conditions. The lecture continues even though it is conducted in cyberspace. Higher education activities at Andalas University must continue even though they exist in the real and virtual world but in essence, still produce real products, namely humans who believe and fear God Almighty and have noble, healthy, knowledgeable, capable, creative, independent, skilled, competent and cultured for the benefit of the nation. In addition, higher education activities must also realize the application of science to a society based on reasoning and research work that is useful in advancing the nation's general welfare and intellectual life. By adhering to the mandate of higher education to achieve these educational goals, engineering applications have been made to the public to reduce the impact due to the handling of Covid-19 in Padang City. This activity is participating in distributing foodstuffs to people who are severely affected by the Covid-19 pandemic and helping to reduce the spread by providing hand sanitizer in places where people can potentially gather. This contribution also helps educate the public to reduce the risk of the impact of Covid-19 by designing, creating, and distributing healthy educational materials in cyberspace. This activity has been successfully carried out to participate in dealing with the problem of the Covid-19 pandemic and is still ongoing with the spirit of learning and working from home; maintaining distance is the best way to break the chain of spreading this virus by working well together between the academic community of Andalas University with the Government and Society.

Abstract

Di Indonesia penyebaran tanah lunak luasnya diperkirakan sekitar 20 juta hektar atau sekitar 10 persen dari luas total daratan Indonesia. Tanah lempung lunak umumnya memiliki nilai kuat geser rendah, untuk itu diperlukan stabilisasi tanah guna memperbaiki sifat tanah tersebut sehingga memenuhi persyaratan kekuatan tanah. Penelitian ini melakukan stabilisasi tanah dengan menambahkan bahan tambah berupa Palm Oil Fuel Ash (POFA). POFA merupakan hasil dari pembakaran cangkang kelapa sawit pada suhu 700°C hingga 900°C. Penelitian ini bertujuan mengidentifikasi tanah lempung di Jurusan Teknik Sipil Universitas Andalas dan menganalisis nilai kuat tekan bebas (UCST) tanah asli dan campuran dengan POFA. Penelitian ini meliputi uji Atterberg, kuat tekan bebas dan kompaksi tanah asli dan dengan campuran POFA pada kadar  4%, 12%, dan 16%. Untuk pengujian UCST sampel diuji setelah pemeraman tujuh hari, dengan separuh diuji langsung (unsoaked) dan separuh direndam empat hari sebelum diuji (soaked). Hasil menunjukkan bahwa peningkatan kadar POFA meningkatkan nilai UCST dan kuat geser tanah. Untuk unsoaked, nilai qu berkisar antara 0,582 hingga 1,600 kg/cm², dan untuk soaked adalah 0,557 hingga 1,422 kg/cm². Nilai kuat geser (Cu) juga meningkat seiring dengan penambahan POFA, sejalan dengan penelitian sebelumnya oleh Rama dkk, (2015).
