Abstract
To improve health service, we can do by using new technology. One example of technology development in health is telemedicine. In this case, the patient data management integrated with electronic checks payments with one card. For that, in this final project is made using smart card system integrated with Unhas Clinic Website. Smart cards that are used by researchers are based on the Consortium Smart Card Indonesia iRFC v 1.0, while the PHP programming language is used to design the website. The creation of MySQL databases and Apache web server responsible for the request-response HTTP are combined in an application called XAMPP. This forms a system that uses a smart card which can save patients’ medical records and perform electronic payment transactions (e-payment). There are 10 people who have been registered as patients on the Website System of Unhas Clinic where 2 of them are insurance patients and have successfully completed the examination. In addition, the examination process at the Website of Unhas Clinic can be done on short distance (0 Km) and long distance (20,3 Km) by using Wireless Fidelity (Wi-fi) network operating system (uplink: 2,94 Mbps; downlink: 20.37 Mbps) and cellular networks such as Provider 1 and Provider 2 (average uplink: 7.1 Mbps; downlink: 5.15 Mbps) with fast connectivity.

Impacts of Grid Frequency Variation on Dynamic Performance of DFIG Based Wind Turbine
Authors: Shiddiq Yunus A. M. 
Published: October 2019

Abstract
Wind energy is one of popular sources of renewable energy that massively used to generate electric power nowadays. Among wind generator technologies, Doubly Fed Induction Generator (DFIG) is placed as the first dominant wind generator type that is installed worldwide since 2004. Its popularity is due to the advantages of its capability to extract more energy compare to the fixed speed type. Moreover, it uses only one-third converter size which reduced the total construction cost compared to its closest rival, Full Converter Wind Turbine Generator Type. Although DFIG widely installed worldwide, it is in fact, very sensitive to the grid disturbances such as frequency variation. Based on IEEE standard for 60 Hz system, a power system should not be allowed to work in less than 59.3 Hz or more than 60.5 Hz. In this paper, DFIG-grid connected is extensively simulated in the condition of frequency variation that is carried out using Matlab/Simulink. The results show that some important parameters such as power output of the generator, voltage at point of common coupling, voltage at DC link and generator speed are experiencing significant rise/drop which in turn might damage the wind turbine generator.

AbstractThis study present an investigation of thermal performance of spiral-tube ground heat exchanger (GHE) buried in shallow depth of borehole. The spiral-tube GHE consisting of spiral pipe installed in the borehole provides a better performance in application of ground-source cooling system. Experimental study was carried-out by circulating water through the spiral-tube GHE which is buried in the ground of 3 m depth. Temperatures of inlet and outlet water in the GHE were measured and recorded periodically. The thermal performance of the GHE was calculated with different inlet water temperatures. Heat exchange rate for different inlet water temperature of the spiral-tube GHEs are 44 W/m (35 °C), 126 W/m (40 °C) and 110 W/m (45 °C). The results show that the utilization of shallow borehole of spiral-tube GHE is appropriated for application in ground-source cooling system especially for the hot climate like Indonesia.

Published: October 2019

Abstract
Mixture of Low-Rank Coal (LRC) with Candlenuts Shell (CNS) has been carried-out to improve the quality of combustion. The quality of combustion is affected by combustion reactivity, thermal efficiency and combustion emission. This study investigated the effect of the mixture of CNS and LRC to find-out its combustion reactivity. An experimental study has been done to investigate the combustion reactivity of mixing LRC and CNS with the addition of CNS to LRC of 10%, 30%, 50%, 70% and 90% respectively. Testing methods including proximate and ultimate analysis following ASTM Standard and sample combustion in electric furnaces were applied with a combustion temperature of 500 °C, 625°C, 750 °C and 875°C respectively. Oxygen was used as an oxidizer in this experiment. The result of the experimental test shows that the addition of CNS into LRC generally increased its combustion reactivity. This fact indicates that adding CNS into LRC improves significantly the combustion quality of CNS and LRC mixture. The optimum addition of CNS into LRC to increase combustion reactivity is 10%.
The Influence of Topography to the distribution of Ni-laterite deposits of Mangguruh Area, Sebuku Island, South Kalimantan
Authors: Irfan U R , Alimuddin I , Pasalli I B 
Published: October 2019

Abstract
One important factor that influences the optimization of the formation of nickel laterite deposits is the slope of a region's topography. The Mangguruh area in Sebuku Island in South Kalimantan is composed of ultramafic rocks on a gently flat topography but forms laterite deposits of varying thickness. Based on the exploration data from 33 drilling points and field data acquisition, this study aims to: 1) create topographic slope groups with varying ranges to determine the range most suited to real conditions in the field, 2) determine the laterite thickness, 3) analyze the concentration of Ni and Fe in limonite and saprolite layers, 4) analyze the effect of topographic slope to the laterite thickness. The method used is the measurement of topographic slope in the field with compass and using ArcGIS software applications in preparing the maps, analyzing laterite profiles from the drilling data and sampling rocks and ores. The study performed a laboratory analysis consisting of petrographic analysis and X-ray Fluorescence testing of the elements. The result revealed that the appropriate topographic slope groups in the study area were 0-5%, 5-10%, 10-15% and ≥ 15%. The laterite thickness of > 10m lied on the slope of 0-5% and 5-10% and contains a moderate-high nickel content of 1.2% -> 1.4%. This indicates that laterite nickel enrichment is influenced by topography. While the distribution of iron ore with medium and high levels of concentration (45-50% and > 50%) has commonly occurred in each topographic slope group indicating that topography is less influential on the distribution of iron ore. Earlier research has indicated that effect of topography on different morphologies is clear and many of the studies were conducted on a regional scale, but interestingly in Sebuku area, the topography is gently flat but the thickness and nickel content is varied. So the results of this study can be applied to slightly flat slope areas and therefore needs more detailed mapping.

Published: October 2019

Abstract
This paper presents an evaluation of Finite Control Set-Model Predictive Control (FCS-MPC) performance for dynamic resources provisioning. Realization of a shared-resources environment is experimented in software system network by virtualization technique. Control parameter regulates the resources provisioning among the users to guarantee the achievement of performance metrics in the network. The objective preferences are maintained in relative term by manipulating a finite set of operating points as the control states. Moreover, an optimization procedure is implemented based on receding horizon prediction of MPC in a feedback control scheme. Further investigation is conducted to examine the performance of optimal FCS and constrained FCS for dynamic system management. The experimental results demonstrate that constrained FCS system provides a better response stability than the optimal FCS. Correspondingly, the range and quantity of input states are significantly influential to the flow of control action. A wider range and longer control state sequence yields to a smoother control signal stream.

Published: October 2019

Abstract
At the coastal areas of South Sulawesi, Indonesia, there are many of villagers work as fisherman, shrimps and fish farmers. Most of them use aerator paddle wheel that are operated by high wattage motors that are ranged from 750 Watt to 1000 Watt. Some others use gasoline engine for one aerator every day. Consequently, the use of high wattage motors will cost the farmers and the use of gasoline will contribute to the air pollution. Therefore, it is necessarily important to invent a renewable base energy source for aerator which in turn economically effective that in the same time could apply the energy diversification. Fortunately, solar and wind potency are quite promising in the area. In this paper, an investigation, examination and application of hybrid solar-wind turbine generator are conducted and applied to aerator paddle wheel for shrimp’s pond. The required energy is 420 Wh/day. The measured average wind speed at Pancana Village is ranged from 3.25 m/s to 5.28 m/s. The averaged solar radiation potency in the village is 975 W/m2. The hybrid system is a combination of two 150 Wp solar panels and 500 W wind turbine. The experimental result show that the solar panels could generate energy by about 370.54 Wh in average, while wind energy could generate 165.60 Wh energy every day. Therefore, it can be concluded that the required energy of the aerator at average paddle wheel of 80 rpm can be fulfilled although solar energy is dominant as energy supplier.

Abstract

Clitoria ternatea flowers have been investigated as a natural sensitizer in Dye-sensitized solar cell (DSSC). Dried C. ternatea flowers ware immersed in ethanol for 48 hours in dark room to obtain anthocyanin pigments. We compared the photovoltaic performance of the sensitizers with Titanium dioxide (TiO2) only and TiO2 with scattering layers. C. ternatea dyes have higher Power Conversion Efficiency (PCE) when applied in TiO2 with scattering layers compared to standard TiO2 semiconductors. Scattering layer (SL) has increased the light path inside the photo-anode film that doubled the short-circuit current (Jsc) and enhanced the open circuit voltage (Voc) compared to TiO2 based cell without the SL. In conclusion, from the result, higher electron injections can be achieved by light management on photo-anode film with scattering layers as one of strategy to enhance the efficiency for further low cost and environment-friendly solar cell.

Authors: Zhu G J , Bo X Y , Feng J J , Wu G K 
Published: October 2019

Abstract
The change of the depth of the inlet collector inserted into the impeller will change the gap shape between the collector and the impeller, and then affect the performance of the ventilator. Taking the small centrifugal ventilator as the object, the influence of the depth of the impeller inserted into the collector on the aerodynamic performance of the ventilator is studied in this paper. Firstly, the depth of the collector inserted into the front disk of the impeller is adjusted to 2 mm, 3 mm and 4 mm respectively to change the geometry of the clearance. Then, based on the computational fluid dynamics analysis method, the influence of the insertion depth of the above three different concentrators on the aerodynamic performance of the ventilator is analyzed. The analysis results show that the gap leakage is positively correlated with the depth of the impeller inserted into the collector, and the aerodynamic performance of the ventilator can be significantly improved by reducing the insertion depth of the collector under the conditions of design flow rate and large flow rate, but under the condition of small flow, the decrease of insertion depth weakens the effect of gap jet on the flow field in impeller, resulting in the decrease of fan efficiency and static pressure.

Authors: Zhao D , Ferguson N S , Squicciarini G 
Published: October 2019

Abstract
A semi-analytical model is developed to predict the acoustic response of thin-walled, orthogonally stiffened cylinders. The free vibration model is solved by the approximate assumed-modes method. The excitation of the normal modes is considered in terms of the Joint Acceptance Function (JAF) for incident acoustic harmonic plane waves. The surface pressure distribution is obtained by the shallow shell approximation, where the blocked excitation pressure is double the incident pressure, and by the 2-D rigid cylinder approximation considering the sound scattering. The acoustic response is then compared with that of a fully coupled FE-BE model. An efficient estimation of the response can be obtained by the two models over a certain range of accuracy. Numerical results for different structural configurations are then given. The effect of the stiffeners on the modal characteristics is discussed. It also illustrates the modal contribution to the total displacement response and addresses both circumferential and axial orthogonally stiffened cylinder arrangements.

Investigating mechanical properties of purplish-red siltstones and mudstones
Authors: Wen T , Huang L 
Published: October 2019

Abstract
We investigate mechanical properties and energy conversion patterns of special rock types (purplish-red siltstones and mudstones) broadly distributed in the Three Gorges Reservoir (TGR) area, China. The mechanical properties deteriorate under unloading conditions. For loading conditions, the cumulative dissipation energy is slightly lower than elastic strain energy before crack propagation stage, while after crack propagation stage the elastic strain energy converts into cumulative dissipation energy. Similar energy conversion patterns are found for unloading conditions. This work offers a new perspective into the failure mechanism of the two special rock types.
