Abstract

Abstract— The primary objective of this research were to produce and evaluate the official Indonesian language version of the Rheumatoid Arthritis Quality of Life instrument (RAQoL). The UK RAQoL was translated into Indonesian by a forward-backward translation. A separate lay panel was conducted to consider the appropriateness and comprehensibility of the items in Indonesian. The translated version of the RAQoL was pilot tested to determine whether the questionnaire RAQoL could be well understood and well accepted. Pilot test was conducted by interviews with 20 subjects, which 10 healthy Indonesia people and 10 rheumatoid arthritis patients who were recruited from X hospital in Yogyakarta, Indonesia.  Items on the two response format questionnaire used in pilot study were scored one for a ‘yes’ response and zero for a ‘no’ response. The individual total item scores with a high score indicating poor QoL. Few difficulties arose in the translation process and the new language version was well received by the lay panel and field-test participants. Statistical analysis was conducted to determine the difference of completion time between healthy subjects and RA patients, and the total score of the questionnaire answers between healthy subjects and patients. The average total score of responses to questionnaire on the healthy subject and patients by T test was significantly different (p < 0.05). The official Indonesian RAQoL was well received by RA patients. The psychometric quality of the translated questionnaire means that it is suitable for validity and reliability of the questionnaire towards patients with RA.Keywords—Rheumatoid Arthritis, questionnaire, RAQoL, translation, pilot test

Abstract

Abstract— Fuzzy Decision Making involves a process of selecting one or more alternatives or solutions from a finite set of alternatives which suits a set of constraints. In the rule-based expert system, the terms following in the decision making is using knowledge based and the IF Statements of the rule are called the premises, while the THEN part of the rule is called conclusion. Membership function and knowledge based determines the performance of fuzzy rule based expert system. Membership function determines the performance of fuzzy logic as it relates to represent fuzzy set in a computer. Knowledge Based in the other side relates to capturing human cognitive and judgemental processes, such as thinking and reasoning. In this paper, we have proposed a method by using Max-Min Composition combined with Genetic Algorithm for determining membership function of Fuzzy Logic and Schema Mapping Translation for the rules assignment.Keywords— Fuzzy Decision Making, Rule-Based Expert System, Membership Function, Knowledge Based, Max-Min Composition, Schema Mapping Translation

Abstract

Abstract–At this time the need for the design of a product is increased. Mattress is a necessity for every individual to rest. Preliminary studies of the function of the mattress stated that the use of the existing mattress found complaints (too large 72%, less attractive 40%, 80% less flexible, less comfortable 40%). Therefore, multifunctional mattress is needed. The purpose of this study is to propose a multifunctional design for a mattress. TRIZ method is used to determine the inventive principles of each attribute and QFD method is used to determine the design parameters of the mattress. Functions that can be developed from a mattress are that it can be folded, it can be a sofa / seating, into the table, flexible /easily removable and as the ironing board. The results of this study shows that the multifunctional mattress design was satisfied the customer feeling and emotion. Keyword–Mattress, TRIZ, QFD, Multifaction, Design

Abstract

Abstract–Wood consumption as building material and component in Indonesia is still considerably high. This affects forest destruction, in a way that most of the wood production still roots from wood forests. Hence, the demand of these woods better be supplied from other source, one of them is through using used woods. Used wood utilization in building construction is an application of reuse and recycle strategy in sustainable material concept. Due to the assumption among the people that used woods have low performance its utilization is nowadays limited. This paper addresses the result of research and laboratory test on a range of used wood samples collected from Jakarta great area (Jabodetabek), consist of 5 technical parameters: water content, density, compressive strength, flexure strength, and tension strength. The research proves that based on certain parameters, used woods perfom technical capacity as good as – or even better than – newly produced woods.Keyword –  sustainable, material, used wood

Abstract

Abstract—Waste and other second-hand goods management in Indonesia are still not properly managed, while used products still have their economic value. E-waste is one of many second-hand goods that are not handled properly. E-waste is defined as the rubbish of electronic products. Mobile phone is one of the electronic products that are almost used by most of Indonesian people, ranging from people having low income to those having a huge income. The influence of lifestyle makes mobile phone lifespan is very short. High level of consumption and short life time make mobile phones are not used accordingly and quickly become waste. When this waste is not managed properly then it will accumulate and damage our nature, because almost all mobile phone components are non-organic materials. Used mobile phones still have economic value and some of their components can be recycled or reused. Therefore this study focuses on promoting reverse handling management of used mobile phones from the Indonesian consumers. The main strategy is aligned with Reverse Logistics concept where value recovery and proper disposal become the main consideration. In this design, a strategy will be discussed throughout the stakeholders who will be involved in the return process so the process can run effectively and efficiently. Consideration of recycling or reusing used product can reduce the retrieval of raw materials from the nature. The problem solution will certainly have an impact on our natural resources balance. When this strategy works successfully then it will certainly contribute in preserving of nature.Keywords— economic value, e-waste, recycle and reuse, reverse logistic, used product.
