Abstract

Abstract. In mining activities with hard rock characteristics, it is necessary to do a blasting which aims to clean the rock, so that it can facilitate digging. The size of fragmentation as a result of blasting will affect to the digging time, the greater of the fragmentation that results will be the longer the time needed to digging the blasting material. Blasting geometry applied by PT. Semen Padang produces fragmentation measuring 53,86 cm with digging time of 14,29 seconds. In this study Blasting Geometry was used with ICI-explosive and RL. Ash theories. Where the fragmentation produced by the ICI-Explosive Theory is 47,86 cm with the digging time of 11,15 seconds, and with the Theory of RL. Ash fragmentation obtained is 43.71 cm with digging time of 8,6 seconds. Of the two theories, the theory of RL. Ash is better because it produces better   fragmentation.Keywords:  Blasting Geometry, Fragmentation, Digging Time, Kuz-Ram, Regression Analysis

Abstract

Education is a means of educating generations of students to gain quality knowledge. This is inseparable from the role of the principal as a manager in achieving the vision and mission of the school. To achieve the mission according to the targets that have been set, this is inseparable from education financing. Education financing is considered important because schools will not run massively if there is no education financing. Education financing itself has a function or use in realizing programs in schools, such as buying infrastructure, providing salaries or wages for teachers, conducting supervisory activities, and many more. It is known that the problem of financing education must always be felt in some schools. This is also the case at Darul Mursyidin Islamic Junior High School (JHS), which has a problem of inappropriate services based on the funds obtained by the school through student tuition and boss funds. This research discusses the management of education financing at Darul Mursyidin Islamic JHS in West Pasaman. The type of research used is through a qualitative approach and descriptive method, where one member of the author, has gone to the field first and seen the facts firsthand. The result is that Darul Musrsydin Islamic JHS in West Pasaman does need to make improvements by taking several steps to restore good quality education financing management for schools.
