Abstract

AbstractSometimes the presence of the union or unions at the company did not have the strength. The position of workers or contract workers is even more difficult, because the protection of the law for workers or contract workers is still weak.Population growth is higher and less balanced distribution of the population, a factor that greatly affects on employment issues in the homeland of Indonesia. In the literature of existing labor law, labor relations history in Indonesia begins with a very bleak future that slavery in which the oppression and inhuman treatment committed by parties capable of socio-economic as well as the rulers at that time.The contract workers can demand higher wages on employers as a result of the prices of basic necessities rise caused by rising fuel prices and employers reject wage hike demands of workers for reasons not yet expired letters of intent. The new labor agreement will expire in 2014.

Abstract

Recently, displacement-based seismic design concept is being developed. According to this concept, structures are designed based on a certain displacement target. This paper presents the application of the displacement-based design concept to reinforced concrete bridge piers of 3, 5, 7, 9 11,and 13 m height. The design results are then analyzed by inelastic time history analysis using Ruaumoko computer program. The results of inelastic time history analysis show that for bridge piers with height 7 m or more, the actual drifts relatively fit the design drifts, while for the 3m and the 5m height piers, the actual drifts are significantly less than the design drifts. Abstract in Bahasa Indonesia : Akhir-akhir ini sedang dikembangkan metode perencanaan seismik struktur dengan konsep berbasis perpindahan. Dengan konsep ini struktur direncanakan berdasarkan target perpindahan yang dikehendaki. Tulisan ini membahas aplikasi konsep berbasis perpindahan pada perencanaan struktur pilar jembatan beton bertulang dengan ketinggian 3, 5, 7, 9, 11, dan 13 m. Hasil perencanaan kemudian dianalisis dengan analisis inelastik riwayat waktu dengan menggunakan program komputer Ruaumoko. Hasil analisis inelastik riwayat waktu menunjukkan bahwa untuk pilar dengan ketinggian 7m atau lebih drift yang terjadi cukup sesuai dengan drift yang direncanakan, sedangkan untuk pilar dengan ketinggian 3m dan 5m drift yang terjadi relatif jauh lebih kecil daripada drift yang direncanakan.

Abstract

Tuberculosis is a disease caused by Mycobacterium tuberculosis. Tuberculosis can be controlled through treatment, chemoprophylaxis and vaccination. Optimal control of treatment in the exposed compartment can be done in an effort to reduce the number of exposed compartments individual into the active compartment of tuberculosis. Optimal control can be completed by the Pontryagin Maximum Principle Method. Based on numerical simulation results, optimal control of treatment in the exposed compartment can reduce the number of infected compartments individual with active TB.Keywords : Exogenous Reinfection, Optimal Control, Pontryagin's Maximum Principle, Spread Of Tuberculosis.
