The Rhetorical Discourse Revealing The Indonesians Characters

Indonesia comprises of many tribes and language spreading all over its islands from Sabang to Merauki. The tribes and their languages are unique symbolizing that they are heterogeneous society who live in a place named Indonesia. They live in harmony and they are happy being Indonesians. This can happen because they have one motto unity in diversity (Bhinneka Tunggal Ika) and a sacred symbol of five principles Pancasila. The symbol of Pancasila and a motto unity in diversity motivate the world to see the unique and harmonious country and its people. What are the real characters of Indonesian and how they are represented in the rhetorical discourse presented by formal speech of president of Indonesia, Mr. Joko Widodo in delivering speech on Pancasila Day 1 June 2017. This article wants to elaborates the characters of Indonesians and the way they are presented in the discourse. This article uses critical discourse of analysis and systemic functional linguistic. This article uses critical discourse analysis and the systemic functional linguistic because the discourse being release is not appearing without any sense. There is a background which escorting the releasing of this discourse. This article finds out that Indonesians have to return to their real original characteristic, such as gotong Royong (supporting each other), Bhinneka Tunggal Ika (unity and diversity) and toleransi (tolerance). They are folded within Pancasila (five principles). Theseidentifications of characteristic are released because the values of Pancasila have been neglected by many group of people after reformation era. As examples are the tolerance is decreasing, the unity in diversity has been disturbed by the existence of other ideology in which it is contradictory to Pancasila. This article found out that there are thre domain idenification of the Indonesian peole that shuld be reestablished. They are supporting each other, unity in diversity and the tolence. They become the pride of the Indonesians and they become the examplary nation which applies the high tolerance among its people. The depicted identifications are clearly stated in the official speech presented by President Joko Widodo in the celebration of Pancasila day 2017. Key words: supporting each other, tolerance, unity and diversity, discourse

Mathematical Communication: What And How To Develop It In Mathematics Learning?

Mathematics is the language of symbols so that everyone who studied mathematics required having the ability to communicate using the language of these symbols. Mathematical communication skills will make a person could use mathematics for its own sake as well as others, so that will increase positive attitudes towards mathematics. Mathematical communication skills can support mathematical abilities, such as problem solving skills. With good communication skills then the problem will more quickly be represented correctly and this will support in solving problems. Students' mathematical communication skills can be developed in various ways, one with group discussions. Brenner (1998) found that the formation of small groups facilitate the development of mathematical communication skills. This paper describes the mathematical communication and how to develop the mathematical communication skills in learning mathematics. For further clarify the discussion, given also the example of learning that emphasizes the development of mathematical communication skills.

Simulation of speed control brushless DC motor using gaussian fuzzy logic controller

This paper presents a control scheme of a Fuzzy Logic for the brushless direct current (BLDC) motor drives. The BLDC motor has some advantages compare to others type of motors. However, the nonlinearity of this motor drive characteristics cause it is difficult to handle using conventional proportional-integral-differential (PID) controller. In order to overcome this main problem, Fuzzy Logic controller with a Gaussian membership function is developed. The mathematical model of BLDC motor is derived. The controller is designed to tracks variations of speed references and stabilizes the output speed during load variations. The effectiveness of the proposed method is verified by develop simulation model in Matlab Simulink software. The simulation results show that the proposed Fuzzy Logic controller (FLC) produce significant improvement control performance compare to the PID controller for both condition controlling speed reference variations and load disturbance variations

Effect of physical and mechanical properties of PU biopolymer membranes upon use of different fabrication techniques

In developing polymer membranes that response to prevents liquid water from penetrating through, while at the same time permitting moisture past out through, polymer membrane with various structure ranging from dense to highly asymmetric morphologies (0.01 - 0.25 mm) were fabricated through three different techniques; blends, curing and grafting fabrication. From FT-IR analysis, BP/PEG (blends, curing and grafting) were fully converted into solid polymer membrane with functional group of N-H stretching in region 3350 - 3250 cm-1. Morphological result of BP/PEG shows three types of surface; open, close and blind surface with cylindrical blind and ink bottle shaped structure randomly. Due to lower porosity of skin over a symmetric support acts as a barrier, BP/PEG polymer membranes resultant no water permeability as compared to BP/DMF, which exhibit extremely higher water permeability with value 0.161 L/s.m3 at lower concentration. Water absorption analysis shows that mechanical properties of the prepared membranes were significantly influenced by their structure and amount of water absorbed. Thus, BP/PEG (blends, curing and grafting) preparation gave lower amount of water absorption with less than 0.01% water absorption increment rather than BP/DMF 12% (w/v) with highly porosity value of 0.07%. Thermogravimetric analysis (TGA) reviewed that the hard segment decomposition temperature was occur at 295 0C – 395 0C, meanwhile for soft segment at 370 0C – 500 0C. Based upon modulus, tensile, strain and tear strength also energy at break, evidently shows that the BP/PEG (grafting) method gave the best performance on physical and mechanical properties with highest mean value of 12419 N/mm, 14.11 MPa, 38.289 %, 50.67 N/mm and 21.627 N respectively. Reciprocally, PEG solvent does significantly increase the mechanical properties with the reaction of BP rather than DMF solvent with varieties of concentration. Moreover, BP/PEG membrane from each fabrication technique had obvious dense porous structural feature with open, close and blind pores in practically boundless development as of adequate final use in membrane application

The new blueprint : Moving towards university knowledge city

All knowledge is a form of tradition, whether ingrained in its structure, content, or the value that people attribute to it. Civilized societies have great traditions of knowledge, and the post modern era which discovered print and digitalization gives leverage to the value of those traditions not only in transforming them into intellectual assets but also the means by which they can systematically improve the way society live, work and continue to change in creative and dynamic ways. Cities-their infrastructure, economies and culture are all being transformed by knowledge. The university is a micro knowledge city, and it needs to develop a larger blue print to sustain its growth as a knowledge city. The university must be aware of the importance to capture knowledge assets within the micro-culture and practice of its academic, professional, pastoral, social and cultural services; the sharing of those knowledge assets; and the transformation of those knowledge assets to leverage life experiences of citizens in the campus knowledge-city, and beyond

The potential of energy substitution in the industrial sector

The extent of substitutability between energy and the other factors (i.e. labour and capital) and between individual fuels (coal, electricity, natural gas and petroleum) is an extremely important question and quite central to energy policy, planning and analysis. This study considers the possibilities of energy substitution in the industrial sector of 5 major energy producers of the developing world (Brazil, China, India, Indonesia and Venezuela). The theoretical model utilized in the study is the two-stage trans-log cost function. The model is estimated using time series data over the period 1978 to 2003. The results indicate substantial inter-factor and inter-fuel substitutions are possible in the industrial sector. Substitution possibilities were found (1) between capital and labour, between capital and energy and between energy and labour in the inter-factor model and (2) for most combination's of fuel types in the inter-fuel model. This implies that there is some flexibility in energy policy options and energy utilization
