Abstract

PT. TIRA AUSTENITE, Tbk (PTATbk) and other companies in the field of supply chain require coordination pertaining cross functional and cross collaboration. The mentioned collaboration is required especially for Expedition Company. The performance analysis of Expedition Company, including PTATbk is needed to face the global competition. Company contribution generally, and in particular for Empirical Study toward PTATBK can lead to the problem solving and performance improvement, which covers selecting optimal expedition company and efficient time to dispatch product from existing route to be integrated into the core essence of this research pertaining PTATbk. The mentioned research refers to Empirical Study dan Managerial Implications through books and journals as reference in the Research Methodology. The focus of this researchmethodology is the Analytic Network Process (ANP); criteria of Price and Service; and other important criteria that support the performance analysis within PTATbk. Software ARENA Simulation plays vital role in this research that has the conclusion and recommendation toward problem solving and performance improvement that are translated into benefits versus risks and its form of % and the currency of IDR and/or USD.

Abstract

Sills, doors and windows is one of the most important parts of the buildings, one type of building that needs them is residences. Nowadays, the development sills, doors and windows are very fast with advanced technology that expands the materials of sills, doors and windows from traditional wood materials to aluminium. The presence of aluminum material choices make the owner of the house could have a role towards sustainable concept but it is inversely proportional to the real situation in which the use of aluminum frames is widely used by the middle class and above. Yet in terms of time, efficiency and quality is still superior to aluminum frames, aluminum frames in which certain anti-termite, easier maintenance and more durable. This situation is considered as the cost of aluminum door sills and relatively expensive. With so many advantages to the frame, people should start using aluminum frames since it is reasonable to pay a higher price for longer durability.

Abstract

The use of additional material as ingredients in the manufacture of concrete mixes is increasingly growing. The material used is also increasingly varied, depending on the expected results. This research aims to know the influence of the addition of coconut fibres material with percentage of 1,5 %, 2 %, 2,5 %, and 3 % as an alternative to the strength of high-quality concrete. Research methods done by producing cylindrical and beam concrete samples for testing against the force then conducted concrete. Furthermore, the analysis has been done and the results of testing and comparing the respective strength of the composition of concrete produced. Based on the test results of data concrete cylinder compression strength and tensile strength concrete beams, it was concluded that the increasing of compressive strength up to 9% can be reached by use of additional material coconut fibers 1,5%and increasing of tensile strength up to 19,7% can be reached by use of additional coconut fiber 2%. Therefore, the additional coconut fibers on concrete mixture has strong relationship to increase tensile strength of high strength concrete.

Abstract

This paper discusses the application of multiple linear regression to measure the efficiency and success of the pattern of groundwater using System of Rice Intensification. The purpose of this paper is to provide an overview of the procedures and the use of multiple linear regression analysis and to measure the impact of independent variables (habits of farmers P3A) in the use of groundwater. Multiple Linear Regression analysis is used to examine the relationships and dependencies between farmers habits P3A to the efficiency of water use patterns of SRI. The results show that the success and efficiency groundwater use is recommended in SRI pattern depends on the habits and behavior of the P3A farmers use ground water for their farming needs.

Abstract

Research aims to create a draft of application based on customer relationship management (CRM) toimprove services on St carolus hospital in terms of criticism-suggestions, to create scheduling events and patient schedule for second time which is still less control. Research used survey, interview the parties concerned, aswell as analyzing the systems running on St Carolus hospital. Results of the research are application design that helps to improve the quality of the hospital service to the patient, application design that helps management in holding the event, and managing the input given by the visitor at ease. In conclusion, the application designhelps manage criticism and suggestions, make events, and intertwine relations with patients after medication or treatment.
