Abstract

Komposit yang memiliki sifat dan perilaku tarik yang lebih baik dibandingkan dengan beton sering dikenal dengan sebutan engineered cementitious composites (ECC). ECC biasanya terbuat dari semen, air, pasir silika, material cementitious, serat, dan bahan tambah lainnya dengan proporsi tertentu. Istilah mortar ECC digunakan karena ECC tersebut tidak menggunakan serat. Abu cangkang sawit (ACS) digunakan sebagai material cementitious pada riset ini. Sedangkan sebagai pengganti serat, digunakan crumb rubber (dengan proporsi 2,5%; 5%; 7,5%; 10% dan 12,5% dari berat semen) untuk membentuk CR-ECC. Workability diukur berdasarkan uji slumpflow yaitu pengukuran T500 dan diameter slumpflow. Tujuan penelitian ini adalah untuk meninjau penggunaan variasi crumb rubber terhadap slumpflow adukan segar CR-ECC yang berbasis abu cangkang sawit. Berdasarkan hasil dari pengujian slumpflow, diperoleh diameter sebaran slumpflow rata-rata (D) dari adukan segar CR-ECC terletak antara 710 mm sampai dengan 930 mm, sedangkan waktu sebaran slumpflow (T500) dari adukan segar CR-ECC yaitu berkisar antara 0,90 detik sampai dengan 1,68 detik. Hasil pengujian slumpflow dari adukan segar CR-ECC menunjukkan workability yang baik, dan sudah sesuai dengan ketentuan standar. Penggunaan crumb rubber dapat mempengaruhi workability karena factor daya serapnya terhadap air, namun keterlibatan penggunaan superplasticizer ternyata sangat berperan dalam mempertahankan workability adukan segar CR-ECC, sekalipun nilai faktor air semen (f.a.s) konstan.

Abstract

Engineered cementitious composites (ECCs) are composites that have better attraction properties and behavior than concrete. ECCs are usually formed from cement, water, silica sand, cementitious materials, fibers, and other additives with a certain proportion. In this study, there are three types of ECC mortars (types AME, EM, and TEM) where these types are differentiated by the amount of cement used, the quantity of water, and the number of sand used. Each type uses ashes of palm shells with the same proportions of 0%, 5%, 10%, and 15% of the weight of cement. According to trial and error during the workability test, the number of superplasticizers used also increased according to the increase in the percentage of ash in the palm shell, where the variation of superplasticizers achieved was 0.70%, 1.59%, 2.49%, and 3.40% of the weight of cement. Based on the results of the slumpflow test, the average diameter of the ECC freshly mixed mortar was between 88 cm and 106.5 cm, and the T500 slump flow was between 0.28 seconds and 1.39 seconds. The test results show a fairly good workability consistency of all ECC fresh mortars, although there has been an increase in the percentage of palm shell ash used. Superplasticizer turns out to be very important in maintaining consistent workability of fresh ECC mortar mix.

Abstract

Many people consider politics as a tool to gain power, it is not wrong but on the other hand politics has a noble purpose. The purpose of this study focuses on the political problems in Indonesia which experience spiritual emptiness and the influence of the spiritualism movement on politics. The method used is a qualitative method with descriptive analysis research to see various aspects of current political problems. As a result of the spiritual emptiness it was found that the politics that developed did not have a direction and purpose, so politics was oriented only to power and not to the people. With this, at least politics in Indonesia must return to the philosophical spirit, which is the welfare of the people. The solution offered is the idea of improving political spiritualism, with religion as the basis for improving the current political situation.
