Abstract

Paving block is made of by mixturing cement portland or other hidrolic material, water, and agre- gate or without any other material. In this research paving blok will be made by using of soil, ce- ment, and rice husk ash. Besides, soaking of paving block is aimed to improve compressive the paving block that is suitable with SNI 03-0691 (1996). The samples of soil that is used came fromq ITERA, South Lampung. The making of paving block samples consists of two stages. First, mixture A (10% of cement, 5% of rice husk ash, 85% of silt soil) and mixture B (15% of cement, 5% of rice husk ash, 80% of silt soil) and the making of samples in the second stage is to deter- mine the effect of immersion of compressive the paving block in which the samples using is sam - ples with optimum compressive result from making samples in the firsh strage by time variant in 0 day, 7 days, 14 days, 21 days and 28 days and also by doing pre-burning and post-burning. From the experiment result of innovation compressive this paving block includes to the quality class D and absorption of paving block that is made of mixturing soil, cement, and rice husk ash is not ap- propriate with SNI 03-0691 (1996). The adding of rice husk ash gives a little influence in improv- ing compressive of paving block. The soaking that is done to paving block causing the decrease of compressive till 45,7%. The highes compressive produced by paving block post-burning during immersion 0 day that is 11,70 Mpa.

Abstract

Teknologi informasi pada zaman sekarang termasuk kedalam sebuah kebutuhan yang diperlukan untuk peningkatan produktivitas pada setiap kegiatan yang dilakukan sehari-hari. Smartphone merupakan salah satu teknologi yang dapat mempermudah aktivitas manusia dalam komunikasi, pencarian informasi ,pengambilan keputusan dan mempermudah pekerjaan melalui aplikasi yang terdapat pada smartphone. Aplikasi Pengenalan Kampus Berbasis Android merupakan salah satu aplikasi utnuk mengenalkan kampus menggunakan smartphoneandroid. Hasil dari penelitian ini menunjukkan bahwa aplikasi android yang dikembangkan dapat dijadikan media pengenalan kampus terhadap masyarakat.
