Abstract

Fly rock is a rock fragmentation that is thrown as a result of blasting. Such fragmentation that is thrown beyond the specified safe distance can cause a damage to the infrastructure, mechanical equipment and humans. This study aims to determine the safe radius of the fly rock that resulting from blasting residential area which that has a distance 200-300 m and has potentially distressing to cause damage. Calculating of the flying rock throwing distance is carried out theoretically and actually with orientation to the distance between spaces, the distance between burdens, minimum stemming height, minimum hole depth, powder factor, average charge blast hole and distance initial burdens. For theoretical calculations, the save distance is calculated by empirical methods and dimensional analysis. Results of the study shows that the maximum distance of the actual fly rock throw is 05.31 m and based on the predictions using the Cratering Method, the maximum distance of fly rocks is 172 m with a safety factor of 2 and the maximum distance of fly rocks is 199.04 m with a safety factor of 2. Based on the actual and predicted data above, it is not safe for blasting locations that is less than 200 m from residential areas, that refers to the safe radius threshold based on the regulation of the Minister of Energy and Mineral Resources No. 1827 K/30/MEM/2018.

Abstract

Augmented Reality adalah salah satu contoh teknologi yang dapat menambahkan obyek di dunia maya ke dalam lingkungan dunia nyata. Augmented Reality dapat digunakan ke dalam bidang pendidikan sebagai media pembelajaran yang inofativ bagi para peserta didik dalam mengikuti pembelajaran karena dapat menampilkan visual 3D dalam bentuk nyata disajikan secara real time Tujuan dilakukannya penelitian ini : 1.) Pengembangan teknologi AR sebagai media pembelajaran, 2.) Memberikan informasi kepada peserta didik dalam mengetahui jenis-jenis kendaraan dengan teknologi Augmented Reality menggunakan platform Android. 3.) Melakukan teknik pengumpulan data dengan cara angket,observasi,wawancara untuk mengetahui respon peserta didik terhadap teknologi Augmented Reality pengenalan kendaraan sebagai media pembelajaran Kata Kunci : Augmented Reality, Kendaraan, Media Pembelajaran

Abstract

In this paper, an application of N-soft set on data with grouped objects will be presented using the construction concept in strait soft set theory to solve a problem in the decision-making process. For each parameter, a weight value will be determined, and from this data, a threshold will be set in such a way that a T-level soft set form is possible. This research is a descriptive qualitative study with a case study approach. An interesting result from this study is that an object with the lowest rank can have the highest rank in a certain group of objects
