Abstract

PT.Bakapindo is engaged in dolomite mining. The mining method applied is the Open Pit quarry method. Currently the mining process is carried out by PT. Bakapindo applies the blasting method to release dolomite rock from its parent rock. In determining the right method for dismantling material, it is necessary to study rock capability. In this study, the method applied to determine the suitable excavation method is by Franklin's rock strength index criteria chart. The data used in the study are discontinuity field conditions taken with the scanline system and rock samples used to test rock strength by means of Point Load Index. Total data on discontinuity field conditions measured in rock mass is 201 data. The results of the point load index test obtained the Franklin (Is) average index value of 4.740MPa. Based on the results of the analysis of rock mass conditions at PT. Bakapindo found that rock mass rating (RMR) of 67 was classified as class II (Good rock), the fracture index value was 0.091m. Based on Franklin's rock strength index criteria graph, it can be concluded that suitable excavation methods are carried out at PT. Bakapindo is byblasting cracks.Keywords: mining method, Index Franklin, rock mass rating (RMR) , Discontinuiy, Point Load Index

Abstract

In Indonesia, the practice of providing education for children with special needs since 1901 has been held by social institutions and religious groups. The radical change began in 1990 when discussing a strong paradigm of inclusive education with humanist content. The core of this paradigm is the existence of services provided towards diversity in uniformity. This paper is intended to explore the paradigm of inclusive education and challenges and opportunities in the Bangka Belitung Islands Province. This paper contains library research and the personal experience while in the field to discuss the Children with Special Needs (ABK) and map the opportunities and challenges of inclusive education services in the Bangka Belitung Islands Province. The findings include: 1) Inclusive education spans a long history to the present, from segregative to inclusive patterns; 2) Educational Development includes multi-dimensional content that includes content modification, approaches debate, structure, and paradigms that support more the sense of humanity; 3) Challenges in Bangka Belitung include the problem of qualified schools that have not reached a balanced ratio with the number of needs; 4) Bangka Belitung has potential that requires good government support, community support, and the socio-cultural conditions of Bangka Belitung that are needed with multiculturalism issue.

Abstract: Effort estimation using Use Case Point (UCP) method obtained from the multiplication of the UCP with the Effort Rate (ER). Some studies conclude that there is some value of ER used in the calculation of effort estimation. However, the most often used is the ER with value 20 man-hours given by Karner. Disputes about the research that is ER by Karner occurred in 1993, so it is possible that the ER by Karner not suitable when applied in the calculation of effort estimation for the project worked on in 2013 and the years to come. This study used 8 data of governance website software development projects. The data is used to calculate actual effort, making use case diagrams, and calculations UCP estimation. Further level of analysis that is performed correlation and regression equations for actual effort and the UCP estimation. Based on the regression equation then performed calculations tangent θ to produce the ER. From this research produced the ER as big as 5,178 man-hours. The ER is much smaller than the value given by Karner ER. Case is possible for several reasons, among others: 1) Enginering software technology that is growing rapidly. 2) Manufacturing website using components. 3) Source of the internet so complete.

Abstract

 Shark liver oil which becomes the main product for groups of fisherman in Cilacap was produced for  traditional food suplement as health product which contains squalen. But the fishermen who processed did not pay attention to the process how to get the shark liver oil stuff so the squalen product could not be guaranted yet as health product. The research aim was to improve the squalen-degree quality of shark liver oil organoleptically.This research was an experimental research.  Shark liver oil of bottle-type shark was processed by using a tool which was planned to produce it. The result was analyzed quantitatively to get squalen degree then it was compared to the squalen standard product in the market. The other quality aspects were the physical performance and its organolepty especially of the smell which caused problem. Shark liver oil product of this research was higher than that of standard product in the market and more qualified organoleptically because of the appropriate technology which was applied in its production. The comparison of squalen degree of this research comparing to the standard product in the market is 141 to 191 times bigger. The technology in this research used principle heating of perfect black thing producing more constantly heat in which the heat caused the oil out of shark liver organ. After the oil put into the container in that equipment, the oil was passed or refined using zeolite stone that  absorbed substances that were undesirable. Absorbent chemical characteristic of this zeolite stone that would absorb undesirable subtances from the production process of shark liver oil so unpleasant or fishy smell of the oil would be reduced when compared to traditional production processes that relied on more stable direct sun heating without being filtered or refined with zeolite stone. This instrument produced more stable heating process and conditioned the process in the clean room so it could minimaze the contamination from outside. The characteristics of zeolite stone as an absorbent could absorb the undesirable substances like amoniac, so unpleasant smell could be reduced.  Keywords: Squalen, shark liver oil, cilacap
