Choosing a major is not an easy matter. There are many factors that must be taken into account and carefully thought out so that in choosing a major, it will cause big losses. There are many ways to determine the selection of majors, one of which is by using fuzzy logic. Determination of majors is determined from the results of the selection test in the academic field with the subjects of Mathematics, English and Computer Knowledge. With the aim of recommending the selection of the right major according to academic abilities and improving quality. By using the fuzzy inference model Mamdani max-min method. The system simulation was tried using the MATLAB Fuzzy Toolbox software. The system design is carried out in several stages, namely: (1) formation of fuzzy sets, (2) formation of rules, (3) determination of the composition of rules, and (4) confirmation (defuzzification). Defuzzification is carried out using the Composite Moment method, with the types of membership functions used are mf-triangular, mf-trapezoid and mf-gaussian. From the results of the tests carried out, it shows that the mf-triangular and mf-trapezoid membership function types produce almost the same level of accuracy. While the membership function type mf-gaussian produces a high level of accuracy for mathematics by 87.50%, English 100% and computer knowledge 81.58%.

Grand Sirao Hotel is a hotel that stands in the middle of Medan City, located on Jl. Semarang. Grand Sirao Hotel is an attractive hotel in the sector of cooperation in certain fields, but in this hotel it often happens in cooperation with outside companies. One of the problems that often occurs at the Grand Sirao Hotel is the constrained stock of goods needed for guests staying at the hotel, items that are often constrained which are usually in the form of sandals and toiletries that are in short supply. This problem often arises because of the many other factors between companies related to hotel owners themselves, debates that often arise from hotel owner claims include quality of goods that are sometimes incompatible with reservations and need to be taken into account, inventory can be exhausted, prices always go up because of skyrocketing market prices and other problems. This collaboration problem arises due to lack of success in determining partnerships with related companies that are not appropriate and in company selection is also still manual and there are appropriate systems and criteria. Therefore a decision support system is needed in the selection of partners upon the proposed approval. One solution to this problem that is right is to make a decision system in the decision of the company's business partners so that the determination of cooperation in accordance with the right requirements. By using a Decision Support System (SPK) is expected to help the company in making decisions made by the right company partners in increasing the efficiency of the decision. PSI (Index Selection Preference Method) is a method for solving multi-decision making (MCDM) decisions. In the proposed method it is not necessary to submit among the attributes. There are no attributes required in computing that are involved in decision making. It is hoped that by using the PSI (Index Selection Preference) Method, it is necessary to establish a decision support system which can assist in the selection of corporate cooperation partners at the Grand Sirao Hotel.Keywords: Determination of Cooperation Partners, Decision Support System, PSI (Index Selection Preference)

Dynamic Olfactometry

The EN 13725:2003, which standardizes the determination of odour concentration by dynamic olfactometry, fixes the limits for panel selection in terms of individual threshold towards a reference gas (n-butanol in nitrogen) and of standard deviation of the responses. Nonetheless, laboratories have some degrees of freedom in developing their own procedures for panel selection and evaluation. Most Italian olfactometric laboratories use a similar procedure for panel selection, based on the repeated analysis of samples of n-butanol at a concentration of 60 ppm. The first part of this study demonstrates that this procedure may originate a sort of “smartening” of the assessors, which means that they become able to guess the right answers in order to maintain their qualification as panel members, independently from their real olfactory perception. For this reason, the panel selection procedure has been revised with the aim of making it less repetitive, therefore preventing the possibility for panel members to be able to guess the best answers in order to comply with the selection criteria. The selection of new panel members and the screening of the active ones according to this revised procedure proved this new procedure to be more selective than the “standard” one. Finally, the results of the tests with n-butanol conducted after the introduction of the revised procedure for panel selection and regular verification showed an effective improvement of the laboratory measurement performances in terms of accuracy and precision.

Students rank requires several considerations and criteria. Determination of the criteria must be prepared as much as possible because it is related to the selection of outstanding students. However, this ranking is considered less than optimal and requires a long time because it is processed manually by the school. The right Decision Support System is needed to produce quick and accurate ranking decisions. This study uses the Preference Ranking Organization Method for Enrichment Evaluation (PROMETHEE) as a Decision Support System. This method will use multi-criteria as the main input in decision making. PROMETHEE will be used to analyze criteria based on alternatives compared to rank according to students' grades and abilities. Based on the research sample data, the highest value was 0.739 for alternative A16. This shows that alternative A16 is the best alternative compared to other alternatives based on consideration of all criteria. The development of PROMETHEE with application-based Decision Support Systems is much better because it produces fast and accurate calculations.

The authors of article draw attention to the fact that currently there are provided many sciences with a component "metry" in its name, for example, there are such developed and meaningful sciences as: Econometrics.Biometrics.Isometry.Scientometrics.Educometry.Sociometry.Referentometry. However, the scientific data are private and do not solve the general-methodological problems. For the super-complex socio-economic systems problematics of "metry" is multiplied many times over and transformed into a philosopho-vozrenologic and paradigmatic-conceptual field of knowledge. We propose approval having the force of law: any super-complex system has a vertically integrated structure and its analysis should take into account these features. It is proposed an analysis sequence intending particularly the following steps: determination of the analysis goal, selection of the research object, determination of the research object properties, etc. An example providing by its goal selection of indicators is suggested to measure the characteristics of the educational institution functioning. The authors propose a number of indicators to analyze the university activities. The results indicated that it is necessary to distribute terms acceptable for analysis in strict accordance with their semantic capacity, i.e. to use a methodology for the systematization and its section -hierarchimetry. The appendixes to the article present the research results of a number of national universities for the selected proposed indicators.

Although the demand for the lithium-ion battery for electronic consumers and electric vehicles in Indonesia is high, there is no supplier coming from the local manufacturer. The proper selection of suppliers is required by some lithium-ion battery manufacturers (cells, modules, and packs), and Research and Development (R&D) center of the lithium-ion battery with the consideration not only in benefits and cost but also in opportunities and risks. It is important that experts assist the manufacturers and R&D to procure the lithium-ion (materials and cells), through transparent methods that seek a quantitative model to select the right supplier. The main objective of this study is to propose an analytical approach to select suppliers which incorporate Benefits, Opportunities, Costs and Risks (BOCR) concept that comply with the characteristics of the lithium-ion battery industries. A fuzzy Analytical Hierarchy Process (AHP) model is developed by accommodating the vagueness and inaccuracies of expert elections. The result of this research is development of the model obtained from 2 questionnaires given to the expert. Questionnaire 1 was made for the determination of criteria and sub-criteria, while Questionnaire 2 aims to perform pairwise comparisons of existing criteria and sub-criteria. In the selection of the lithium-ion battery suppliers, there are 11 criteria and 40 sub-criteria which are considered. Those criteria are divided into 4 merits and known for their respective global priorities.

This study explores the mineralogical composition of the material of samples extracted from the outcrops of amphibolites located within the Kryvyi Rih Basin. Amphibolites of the Novokryvorizka suite of the Kryvorizka series are located in the area of Rodina mine of the Kryvyi Rih Iron Ore Enterprise (KRIOE) on the right bank of the Saksahan river, where the amphibolites crop out as an interrupted line. Over the recent years, industrial and geological tourism has been actively developing not only within Kryvyi Rih, but also in Ukraine in general. The Kryvyi Rih Basin has many objects which deserve the status of unique geological observation sites. One such site has amphibolites of the Novokryvorizka series, which rarely outcrop to the surface. Such an object is interesting and useful not only for interested tourists, but especially for geology students as an example of rocks that have been formed out of effusive eruption products during the geological process such as regional metamorphism. No other examples of their exposure have been observed in the area. The studied outcrops are unique, but recently, their reduction has been observed due to the poor level of their preservation. The relevance of this study is conditioned by necessity of conducting geological evaluation of the amphibolite outcrops with a view to the future use of this object for development of industrial and geological tourism within the Kryvyi Rih Basin. We studied all possible outcrops of the amphibolites within the surveyed territory, and analyzed the results of the previous studies on the topic. We developed a schematic image of the outcrops with consideration of their thicknesses. The mineralogical composition of all outcrops of the amphibolites was studied for further determination of the exact age of the amphibolites and opportunity of providing the amphibolite outcrops with the status of unique observation sites. For achieving the goal, we used the following methods of study: geological survey, selection of representative petrographic samples of the amphibolites, mineralogical and petrographic analyses, generalization of results of field and laboratory studies.

Sustainable development principles aim to re-utilize wastes to reduce their impact on the environment. In this context, the present contribution shows preliminary results on the preparation of innovative synthetic lightweight aggregates, starting from biomass-derived fly ash and high-density polyethylene (HDPE), to be used in geotechnical applications. The present work focuses on the manufacturing process of aggregate blends (including the selection of the right proportions of the two components) as well as on the relative determination of (i) physical–chemical properties (i.e., chemical composition, morphological analysis, mineral leachability, water absorption, specific gravity, grain size distribution); (ii) permeability features and (iii) mechanical properties (one-dimensional compression and shear strength behavior). The results, gathered from the new synthetic lightweight aggregates and compared with the corresponding ones obtained in a previous study conducted on natural and synthetic lightweight aggregates, appear promising for a potential utilization in geotechnical engineering.

Recruitment is not an arena of  “hazing”  and  the  addition  of  bureaucracy  but a forum to explore the nature of integrity, capability, and independence of the candidates for constitutional judges. The process of recruiting candidates for constitutional judges to choose the recruitment system based on the principle of transparency, participatory, objective, and accountability to the people of the early stages and mechanisms of recruitment until the determination of the constitutional judges candidates that can lead to public confidence and form of democracy because of the position of the control and balance between state with people. Thus, the recruitment process needs to be accompanied by a written rule that can evolve as needed to create the best candidates for constitutional judges based recruitment process by filing recruitment agency and SOP (Standard Operational of Procedure). The problem is not on the persons making the recruitment, agency nominate candidates for judge, and the lack of setting the terms of the constitutional judge best candidate, but the choice of constitutional judges are recruited to promote open to the public process. DPR as one of the agency of the state to file a constitutional justice through the recruitment team can choose the right man in the right position through the selection of recruitment mechanism in accordance with the constitutional.
