Judul: Analisis Pemenuhan Klausul Integrated Management System di PT Tirta Investama Plant Ciherang
Abstrak: Integrated Management System (IMS) is a management system consists of some management systems which implemented simultaneously. The objectives of the internship were to identify the integrated system and fulfillment of the IMS clauses in PT Tirta Investama Plant Ciherang. The data were collected by IMS documents review. Fulfillment of the IMS clauses was conducted through pre audit internal to evaluate the documents’ compliance. IMS applied in PT Tirta Investama Plant Ciherang consists of Quality Management System ISO 9001:2008, Food Safety Management System FSSC 22000, and Environmental Management System ISO 14001:2004. The results of pre audit internal showed that from 124 IMS clauses, it was found that 88% of documents were complied with the system, 1% categorized as major incompliance, 10% minor incompliance, and 1% observation. The corrective and preventive actions were determined afterward for each incompliance and observation

Judul: Kajian Efektivitas Penerapan Sistem Manajemen Lingkungan ISO 14001 di PT. Indocement Tunggal Prakarsa, Tbk. Citeureup, Bogor
Abstrak: PT. Indocement Tunggal Prakarsa. (ITP) Tbk. Cietureup, Bogor has implemented ISO 14001 since September 2002 and still retain such accreditation. The objective of this study was to determine the effectiveness of the implementation of the environmental management system ISO 14001 in PT. ITP Citeureup especially study the effectiveness of the management of significant environmental aspects which include: dust emissions, exhaust emissions, noise, hazardous and poisonous waste spill, and hazardous and poisonous waste utilization. In this research, the methods used are secondary data collection procedures in the form of company activities and data measurement results of monitoring of emissions of dust, exhaust emissions and noise levels. The Data compared with the standard ISO 14001-2005-19 and of legislation, so that it can be determined the effectiveness of the application of ISO 14001 in SML PT. ITP Citeureup. Based on the research results, in General, the implementation of ISO 14001 environmental management system in PT. ITP Citeureup weren't entirely effective, as there are several articles that have yet to comply with standards and regulations.

Judul: Approximation of the Median of Poisson Distribution Using the Relation of Poisson-Gamma Distribution
Abstrak: A major drawback of median is that median cannot usually be defined in closed form, even in the cases where their distribution functions are known. This study gives an approximation of the closed form for the median of the Poisson distribution by using the relation of Poisson-Gamma distribution. The approximation uses elementary techniques based on the monotonicity of certain sequences involving tail probabilities of the Poisson distribution and the Central Limit Theorem. Furthermore, a closed form expression for the mean absolute deviation 􀜧|􀜰􀰒 􀵆 􀜯􀝁􀝀􁈺􀜰􀰒􁈻| is also studied. The median is relevant because of the fact that it minimizes the mean absolute deviation of a Poisson random variable (􀜰􀰒􁈻 by considering median as central tendency.
