The Combination of RSA And Block Chiper Algorithms To Maintain Message Authentication a Sepri Yanti Tarigan and 2 Devita Permata Sari.
a Magister of Information Technology, Universitas Sumatera Utara b Sekolah Tinggi Teknik Poliprofesi Medan. RSA algorithm is one of the popular public key algorithm used and even still used today. The strength of this algorithm lies in the exponential process, and the factorial number into 2 prime numbers which until now takes a long time to do factoring. The RSA scheme itself adopts the block cipher scheme, where prior to encryption, the existing plaintext is divided into blocks of the same length, where the plaintext and ciphertext are integers between 1 to n, where n is typically 1024 bit, and the block length itself is smaller or equal to log n 1 with base 2.
With the combination of RSA algorithm and block chiper it is expected that the authentication of the message can be maintained. The secured message will be encrypted with RSA algorithm first and will be encrypted again using block chiper. And conversely, the chipertext will be decrypted with the block chiper first and decrypted again with the RSA algorithm.
This paper suggests a combination of RSA algorithms and block chiper to secure data. The Sustainability of Public Transport in Medan, medis s surbakti.

TAGUCHI EXPERIMENTAL DESIGN TO IMPROVE THE QUALITY OF COFFEE POWDER PRODUCE BY AMADANOM COFFEE INDUSTRY, MALANG Wisnu Wijayanto Putro, Oyong Novareza, Suluh Elman Swara, Rio Presetyo Lukodono, Ihram Rachmansyah.
This research was conducted with a view to improve the quality of coffee powder produced by Amadanom Coffee Industry in Malang. The taguchi experiment design was performed to obtain a combination of roasting parameters which could in turn improve the quality of coffee powder. During the roasting process, the acids that were naturally contained in coffee beans were transformed into acetic acid, malic acid, citric acid, and phosphoric acid, which in turn contributed to the coffee s actual taste.
According to the ANOVA calculations, several key factors contributed to the actual taste of coffee powders. These were often not paid sufficient attention, resulting in their not having definite standards, which contributed to the low qualities of coffee powders, such that they failed to attract sufficient attention of consumers. They are Roasting Temperature, Duration of Roasting, the Weight per Roasting, and the Cooling Duration.
Organoleptic tests had been performed to rate the quality of coffee powders resulting from taguchi experiments, bearing in mind the four mentioned indicators. From the response tables, ANOVA predictions, and SNR, the optimal setting level was obtained that hopefully could help to improve the quality of coffee powders. One factor of the highest significance to the quality improvement of robusta coffee powder used in this experiment, was the composition of Factor A2 Roasting Temperature of 185 degrees Celcius ; Factor B1 Duration of Roasting of 20 minutes ; Factor C2 Weight per Roasting of 7.
5 kilograms and Factor D2 Cooling Duration of 10 minutes. Those factors were the ones used during the confirmation experiment. The organoleptic tests of the resulting coffee powders showed an average of 4. 93 with regards to consumer rating. This meant that the average consumer of robusta coffee in Malang liked this product. The result was also far-off from those during the preliminary tests, when the stated average result for the Amadanom industry s product was a mere 1.
89; which effectively reflected consumers dislike for the product. Therefore it was hoped that the implementation of the optimal setting level could soon be initiated by the Amadanom Village s Coffee Industry, of Dampit District, Southern Malang Regency, in order to produce coffee powders of better quality and thus more favorable to consumers. Seismic behavior of low-rise precast concrete bearing wall buildings Ekkachai Yooprasertchai a and Pennung Warnitchai b.
a Faculty of Technical Education, Rajamangala University of Technology Thanyaburi 39 Moo1, Rangsit-Nakhonnayok Rd.Klong 6, Thanyaburi, Pathum Thani, Thailand ekkachai_y at rmutt. th b School of Engineering and Technology, Asian Institute of Technology, P. Box 4, Klong Luang, Pathumthani, Thailand. This paper presents the seismic performance of one-half scaled precast concrete bearing wall specimen representing 2-story residential buildings widely constructed in Thailand.
The wall specimen was cast from manufacturer, transported to the site, and installed on cast-in-situ foundation. Two reinforcing bars were protruding from the foundation and inserted into corrugated ducts pre-embedded in the panel. The ducts were later filled with non-shrink grout cement to achieve structural integrity. A quasi-static cyclic loading test on the specimen was carried out to evaluate seismic performance of the in-plane wall panel.
A simple fiber model was then developed using the RUAUMOKO computer program and validated with the experimental results. A series of zero-length, compression-only nonlinear springs are adopted to simulate nonlinear responses of concrete at the wall base. The nonlinear behavior of reinforcing bars crossing the wall-foundation interface was modeled by an axial tension compression spring which can simulate the initial and post-yield stiffness, and yield strength of the bar using the Ramberg Osgood hysteretic rule.
The research indicates that the wall panel specimen was significantly stronger than its connection. The specimen reached its peak at a drift of 0. After the peak, the force gradually decreased and the force-displacement evidently demonstrated unstable loops. One reinforcing bar was fractured at the second drift of 0. 5 while the another was broken at the first drift of 0. No crack was observed on the wall panel. It was obviously observed that the source of lateral displacement was mainly dominated by a rocking deformation through creating large single crack at the wall-foundation interface.
The analytical study showed very good agreement with the test results. The simple model could be used to predict performance of the wall.

Analysis of a three phase six pulse Static Syncrounous Compesator Janne Deivy Ticoh, Moureen Moudy Kambey. 5cm x 10 cm plastic box. A Static Syncrounous Compesator has superior performance during low voltage condition as the reactive current can be maintained constant In a SVC, the capacitive reactive current drops linearly with the voltage at the limit of capacitive susceptance.
The circuit consists of six switches, made up of six GTO thyristors with antiparallel diodes connected as a six pulse Graetz bridge. The analysis of the circuit assumes that each switch is turned on only once in a cycle of supply voltage and conducts for 180 degree each. To simplify the analysis, to derive the equations describing the steady- state performance, assumed initially that i the capacitor size is infinite very large and therefore the DC side voltage is constant, and ii the losses in the circuit are neglected.
A STATCOM has superior performance during low voltage condition as the reactive current can be maintained constant In a SVC, the capacitive reactive current drops linearly with the voltage at the limit of capacitive susceptance. A STATCOM is comparable to a Synchronous Condenser or Compensator which can supply variable reactive power and regulate the voltage of the bus where it is connected. A high power GTO based STATCOM is a six pulse circuit.

Universitas Katolik De La Salle Manado. Pre-positioning of Critical Relief Supplies to Support Emergency Response in Multiple Disaster Areas Prudensy Febreine Opit. This paper aims to develop a new stock pre-positioning model to support emergency relief response in the event of an earthquake.
In this paper, the earthquake may hit multiple disaster areas at the same time and forces the distribution center to provide service to one or more disaster areas. Hence, this new model determines the maximum proportion of relief demand covered in distribution centers for each scenario. The scenario is considered based on the assumption that at least one or maximum of two adjoin disaster areas hit by the earthquake at the same time. To solve this model, first, we assign the service area of each distribution center.
Next, by using the result of the assigned service area, we determine the minimum value of the lower bound of proportion of unsatisfied relief demand Stage I. Afterwards, we use the output of stage I as an input to determine the maximum amount of critical relief supplies to be stocked in each distribution center Stage II.

Numerical Study of Flame Stabilization in Micro-combustors with Different Designs of Meso-scale Tubes and Wire Mesh Position Danar S. Wijayanto, Herman Saputro, Aris Purwanto, Laila Fitriana, ,F. Recent developments in micro power generation have shown that combustion within a confined space; even in sub millimeter scale is achievable. In recent years micro power generation systems have been seen as potential alternatives to batteries due to the higher energy densities of hydrocarbon fuels.
The combustion characteristics of micro-combustors in different designs of meso-scale tubes and wire mesh position were studied numerically in order to get the flame stabilization. Generally, the difficulty in sustaining combustion in micro scale devices is related to the substantial heat losses due to the large surface area to volume ratio and the physical time available for the combustion to occur.
To stabilize flame in micro-combustors, a proper thermal management is required. Many approaches can be utilized to enhance the flame stability. The simulation was conducted in 2-D and 3-D steady state model by using the ANSYS Release 14. The fuel type used was propane C3H8 air mixture. The inner diameters of the combustor are 3. 5 to 5 mm and the wall is 0. The results have shown that the position and model of the designs of meso-scale tubes and wire mesh position have direct relationship with the characteristics of flame stabilization in the micro-combustors.

GENDER BIAS IN THE WORKPLACE SHOULD WOMEN BE MARGINALIZED IN ENGINEERING JOB. Yusuf Kurniawan and Ismi Dwi Astuti Nurhaeni. Universitas Sebelas Maret Surakarta. Although gender-mainstreaming has been echoed by governments of many countries, gender bias at the workplace is still ubiquitous. The research in various countries, including in Indonesia shows that women tend to be marginalized in technical jobs.
Gender-stereotype, in which women are positioned in jobs relating to domestic sphere still occurs. Such practice shows the unequal opportunity to certain positions and career development. Research observing women marginalization in the workplace viewed from the end-users have not been widely done. This article discusses about gender bias in the workplace from the perspective of the end-users of vocational higher education in terms of first, the views of entrepreneurs towards certain job positions whether they are more appropriately occupied by male or female employees graduating from vocational schools, second, the companies policies in the salary payment regarding male and female employees graduating from vocational schools, and third the availability of companies policies in fulfilling the gender needs for male and female employees graduating from vocational schools.
This research was conducted in Sragen Regency, Indonesia. The primary data were collected through in-depth interviews to 10 entrepreneurs, comprising of 5 men and 5 women who manage different companies whereas the secondary data were collected through documentation studies. The research result shows that both men and women as entrepreneurs have a gender-biased view of the position of women and men within the companies. This research uses gender analysis. As a result, women s salary tend to be lower than that of men for the same job and the companies were still not responsive to the different needs of women and men.
In other words women are still marginalized in engineering job. Accordingly, local government should supervise the companies to implement gender mainstreaming in the workplace, especially in the employees career development. The local government should also award rewards to companies implementing gender equality and otherwise it should also give punishment to companies which have marginalized women in the workplace.
