Abstract

Exchange currency rate becomes one of the most important things on country economic growth. In some countries, the rate may affect seriously to economic growth and political stability. Governments need to have some actions in order to stabilize the rate. Knowing the pattern of exchange currency rate is a mandatory by governments for determining their future policies or as consideration in future decision-making. Therefore, government needs an analysis tool for modeling the rate prediction. Our previous study emerged that using deep learning method with encoder-decoder architecture has succeeded to model the rate prediction with teacher forcing and give only a one-step prediction. In this study, the authors aim to predict the pattern of exchange rate using the previous method with zero input to decoder to obtain multiple time steps prediction. After training and testing over 4,344 daily data series of IDR to USD exchange currency rate over 17 years taken from Bank Indonesia official website, the result found that the method still showed an interesting model to predict the next 40 sequence data series of exchange rate. In conclusion, the proposed method can be utilized to tackle the others prediction problem and the resulted model can be applied as an analysis tool by government for predicting their rate for the coming months or years.

Abstract

One of the Indonesian government's efforts in the provision of clean water and sanitation infrastructure is the provision of community-based water supply and sanitation (Pamsimas) program. In accordance with the principle of community-based, the active participation of the community becomes the key to success in the implementation of the program. This study analyzes critical success factors (CSFs) in water and sanitation infrastructure development projects through community empowerment approaches. The results showed that there are 10 critical success factors, including government and private intervention in infrastructure (technical and financial) through public private partnership (PPP) and corporate social responsibility (CSR) cooperation schemes; development of competence (skill, knowledge, and job behavior) of member of non-government organization in management of empowerment program activity; strengthening community institutions post-empowerment to trigger community self-reliance in sustainability of empowerment programs; balance between availability and accuracy of allocation of funds through the optimization of project/program management, monitoring and evaluation, independent audits, awareness raising on anti-corruption, and transparency of publicly accessible program financial documents; cultural application of science and technology in all aspects of community development; the formation of a sense of belonging to the community towards the results of development (sense of ownership); strengthening the behavioral commitment of the personnel of the community organization to the established organization; and the stimulation of a responsive approach (demand responsive approach), in the meaning, something that is built must really be needed by the community.

Abstract

With the increase of complexity of Android application, the structure of application code will be more complex. The complexity is also affected by the lack of features in the Android framework to build applications with a good structure based on programming principles, such as the S.O.L.I.D principle. This complexity often occurs in the main elements of Android app elements, such as Activity and Fragments. Frequently, the two classes have very much functional, such as handling UI / view logic, business logic, to access data. This enormous functionality has made activities and fragments into God Class which is an anti pattern in programming. Therefore it is necessary to have a good architecture with a clear code structure. The one existing architecture and has been applied to other platforms is Model View Presenter / MVP. By applying this design pattern, there is no more classes that have much functionality because UI / view logic functionality handled by view separately, data access handled by model separately, and presenter access model and updating the view based on user interaction. Furthermore by applying Model View Presenter design pattern which is one of implementation of good programming principles such as Separation of Concern and S.O.L.I.D. makes application (marketplace travel) has a good and clear code structure, modular, and maintainable

Abstract

The development of technical materials, especially polymer composites including high-tech materials, manufacturing processes and engineering applications has shown a significant improvement. The problem that arises along with the development of the technology of polymer composite materials is how to utilize materials whose sources are of sufficient availability and are able to be regenerated to anticipate material crises. Especially the type of polymer plastic, where the availability of material sources is influenced by petroleum sources that cannot be renewed. Based on these considerations, a study of composites with fillers from natural fibers was carried out. Natural fibers used are coconut fiber and palm sugar fibers that are widely available in Indonesia. In this study using an experimental method, by varying the composite raw materials of coconut fiber (0%, 5%. 10%, 15%, 20%) and palm sugar fibers (40%, 35%, 30%, 25%, 20 %), and polyester resin at 6%. The testing standard used is JIS K 7113, which is testing tensile strength in the composite. From the results of the research conducted, it can be concluded that the addition of coconut fiber and palm fiber can affect the composite tensile strength. The value of the largest tensile strength reached an average of 17.67 MPa with a fraction of the volume of coconut coir fiber 20% and palm sugar fibers 20% and the modulus of elasticity 257,1183 Gpa. this shows that the higher the composition of the mixture of coconut fiber to the palm fiber fiber composite, the greater the strength of the tensile strength, due to the nature of the palm fiber fibers that are strong, flexible and not hollow because the cellulose content in the palm tree fibers is lower than the lignin content.

Abstract

The number of small and medium sized metal smelting industries whose working processes produce large waste heat energy. This results in almost 40% of energy being wasted as high temperature exhaust gases. This percentage is able to be converted into electrical energy with the concept of a thermoelectric generator using peltier elements. The way to use it is to use TEG (Thermoelectric Generator) whose function is to convert heat into electricity by utilizing temperature differences. The purpose of this research is how exhaust temperature optimization, the number of peltier elements to the thermoelectric generator voltage output on a used metal melting furnace. Then the analysis is done to get the optimum Seebeck coefficient as a representation of the thermoelectric generator performance. The design of this study is an L20 orthogonal matrix with three replications using a factorial design. The independent variables varied were exhaust temperature, number of peltier elements and data analysis using ANOVA Two Way. Based on the results of the research data it can be concluded that the furnace wall temperature affects the TEG current output. Where the most optimal wall temperature is 480 ºC which produces a TEG current output of 168 mA. This indicates an increase in the temperature of the used metal smelting furnace walls increasing the TEG current output. While the number of peltier elements does not influence the TEG current output
