Abstract

Peat is spread widely in Sumatera Island, especially in Riau Province, Indonesia. Peat is included as problematic soil because it has low bearing capacity. The use of helical pile foundation on peat is one of the innovations to increase the peat’s bearing capacity. In this research, numerical modelling of single helical pile foundation load test on peat were carried out, based on the full-scale test conducted by Suratman (2019). The modelling were done by using PLAXIS 2D 2016 program with Axisymetry model type, with the Soft Soil Creep (SSC) soil model. This modelling aimed to know the failure mechanism of model. The parameters used in the modelling were obtained from laboratory test data and field tests and also from trial and error method. The failure mechanism that occurs on the Soft Soil Creep (SSC) model is more likely to be a cylindrical shear failure.Keywords : Peat, Helical Pile, PLAXIS 2D, Failure Mechanism.

Abstract

Influenza merupakan penyakit pernapasan dengan morbiditas dan mortalitas yang tinggi di seluruh dunia. Setiap tahun terdapat 3-5 juta kasus influenza berat dan 250.000 sampai 500.000 diantaranya mengalami kematian. Penanganan kasus influenza menekankan pada upaya preventif yaitu vaksin. Namun, kelemahan vaksin konvensional adalah pembuatannya harus disesuaikan dengan strain influenza yang berkembang pada musim berikutnya. Karakteristik utama dari virusinfluenza terdapat pada hemagglutinin (HA) dan neuraminidase (NA). Target vaksin influenza universal adalah HA stem region yang memiliki sifat tidak mengalami perubahan genetik. HA stem influenza memiliki epitop konservatif penginduksi broad neutralizing antibodies (bnAbs). Namun, aktivitas induksinya sering terganggu karena adanya HA head region. Oleh karena itu, perlu dilakukan pemotongan HA head region melalui teknik Polymerase Chain Reaction (PCR) untuk mendapatHA stem region murni. Antibodi yang diinduksi oleh HA termodifikasi ini adalah broad neutralizing antibodies (bnAbs). Broadly neutralizing antibodies dapat bereaksi silang dengan influenza varian lainnya. Keunggulan bnAbs tersebut berpotensi untuk menetralisir semua strain influenza baik yang sudah ada ataupun yang baru muncul. Untuk meningkatkan efektivitas vaksin, digunakan nanopartikel ferritin sebagai pelindung vaksin yang potensial. HA stem digabungkan denganferritin melalui teknik rekayasa genetika dengan cara bio-active sehingga terbentuk HA stem yang memanjang pada permukaan ferritin. Berdasar uraian tersebut, vaksin hemagglutinin stem berbasis HA-ferritin nanopartikel berpotensi sebagai vaksin universal protektif jangka panjang.

Abstract

The problem of poverty and unemployment become tremendous challenge to be solved by local government in this autonomy and fiscal decentralization era. Through local autonomy and decentralization, there are obviously greater opportunities to localize the problem of poverty and to take action based on local condition and local contingency factors. Poverty alleviation program initiated by local government should be oriented to be more humanistic with dignity approach, that is taking people in poor as a subject to be enhanced and entrusted to be able to escape from their poverty problem. Through the concept of self-help community, the problem of poverty can be eradicated more effective. The big challenge faced by local government concerning to the poverty alleviation program is to develop strong political and economic democration in a local context. There are at least six pillars that need deep attention to be improved and enhanced, i.e. education, people income, health, regulation and law enforcement, public service infrastructure, and institutional building.
