However, many users are using smartphones too often, so that they forget the time and consciously or unconsciously looked too close and too tilted to the screen of their smartphone. This bad habit that commonly done by smartphone users to correct the eye vision of what they were seeing on their smartphone's screen are highly unhealthy, particularly for their eyes and neck. Previously related research was created to help smartphone users preventing unhealthy reading postures while users in a standing or sitting position but most of the existing research do not researching the monitoring on lying down positions and its variation, especially on supine position. Which based on current research most users always tilt their heads 30° to 60° while reading on their smartphone screen with supine position, and its weight is about 4–6 times heavier than the normal head weight during normal posture. The validated result in this research show that by using accelerometer Z axis and captured image parameters only, it can be detected whether the user position is supine or not and the neck angle can be detected to inform users whether their posture are good or not while using smartphone.","PeriodicalId":382919,"journal":{"name":"2017 7th International Annual Engineering Seminar (InAES)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131593630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the price of DCP is still expensive according to developing contries people. The price of DCP mostly related to its manufacturing that involved many machining processes. The proposed solution offered in this study was to change DCP manufacturing process mainly on the gliding holes making used by machining process to be the forming process. DCP-manufacturing process sequences that proposed was to be: a) making a hole on the plate, b) cutting lengthwise plates to size, c) bending the plate and d) making holes gliding. To bend the plate was used to performed by the press machine. This study introduced rolling process in order to bend the plate. Unfortunately, there was no rolling machine available in market to perform this process, it need to design the rolling machine. This study therefore conducted designing rolling machine required to bend the plate by rolling process prior to make the gliding holes. The rolling design was based on thickness reduction capacity of machine performed by flat roller. The design is limited with power of 3 horsepower electric motor. By mathematical calculations, the horsepower can used to reduce the plate by 0,42mm performing on the 316L stainless steel plate with dimensions of 50 mm in wide and 5 mm in thickness.","PeriodicalId":382919,"journal":{"name":"2017 7th International Annual Engineering Seminar (InAES)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126972141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Geoid application is developed as well as the application of height determination with GPS technology. The height that obtained from GPS observation is geometric height, so that needed modelling precise geoid in order to convert geometric height data to the height data that has physical meaning of the earth i.e. orthometric height. Modelling local geoid requires three wavelength components that consist of long wavelength that obtained by using global geopotential model (MGG), medium wavelength that obtained by terrestrial gravity anomaly and short wavelength that obtained by terrain data. Evaluation take place toward four global geopotential models, they are GGM05C, GECO, EIGEN-6C4 and EGM2008, secondary data of terrestrial gravity anomaly and three digital terrain model of RBI Maps, SRTM30plus and also satellite imagery TerraSAR-X. The result of the Combination Variation combination of MGG and DTM that used in this study produce absolute accuracy that obtained from the difference between gravimetric geoid undulation and geometric geoid undulation on the high spots (TTG) and relative accuracy that obtained from variant-covariance value of gravimetric geoid undulation using Least Squares Collocation (LSC) method. The results of this study indicate that the variation of MGG and DTM take effect to the accuracy of geoid and color pattern that has obtained. Based on the evaluation of using MGG, MGG EGM2008 result the most optimal variant model with 0,4 meters accuracy. Meanwhile based on evaluation of using DTM show the SRTM30plus DTM result the most optimal variant model with 0,4 meters accuracy. After evaluation based on using of MGG and DTM, then obtained the most optimal variant model which has been evaluated against high accuracy standards of topographic survey activities on oil and gas exploration and exploitation activities of PT Pertamina EP Asset 4 Field Cepu.

Forty-five specimens with the initial surface roughness 45pm–55pm are electropolished. The electropolishing process involves 3 parameters: voltage, electrolyte temperature, and processing time. Then, comparison between initial and final condition of surface roughness is done. The results show different results for every combination. The best electropolishing process is shown with a value 16,8% on surface roughness reduction, and the worst one is −17,71%. Recommended variation of parameter is: 3 volts (working voltage), 35°C (electrolyte temperature), and 4 minutes (processing time). This recommendation is based on the lowest parameter and highest reduction in surface roughness with the aim to reduce cost and time production with the best smoothing result.","PeriodicalId":382919,"journal":{"name":"2017 7th International Annual Engineering Seminar (InAES)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123276045","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The old climate quality is only the actual temperature-based controlling. On modern climate, an organization called Cobb-Vantress detached three climate parameters need to be satisfied: 1) temperature, 2) humidity, and 3) wind speed. It is known that those three parameters are not independent, the area to be controlled are fast area while commonly, this available tool to control those three parameters is only the speed of the exhaust fans inside the broiler house. Therefore, controlling three parameters which were intertwined each other inside a fast area with only single actuator was the main problem of this paper. The main goal was to achieve ideal microclimate control to grow chicken inside a broiler house. Alleviating those stated problem, a method that combined PID with artificial neural network was evaluated. The retrieval of the actual climate data were used as an input parameter for the process of identifying ideal climate system and used to control the climate error based-those parameters by generating wind speed to cool the broiler house. Results shows that the climate control that can be implemented effectively to maintain the effective temperature of the broiler house at 32 to 22 degrees celcius from the day-old chick to be matured in brooding stage. To achieve a settle state in the process of tuning PID should be done to get the appropriate PID parameters.

Iswanto","doi":"10.1109/INAES.2017.8068565","DOIUrl":"https://doi.org/10.1109/INAES.2017.8068565","url":null,"abstract":"The welding process causes localized heating at the spliced portion followed by gradual cooling process. The heat input depends on the current, voltage, and welding speed. Local heating and cooling rate causes a volumetric change of the material, which resulted in the spread of heat, distortion, and residual stresses. Distortion may cause aesthetic changes and the size of the welded area. The purpose of this study is to investigate the effect of welding speed on material distortion of the AA5083H116 by MIG and TIG welding using ER5356 electrodes. This study utilizes AA5083H116 material. The MIG welding speeds were varied between 8, 10, and 12 mm/s while the TIG welding speed were 0.8, 1.3 and 1.8 mm/s. MIG and TIG welding was performed using voltage of 19 V, torch angle 45o, and argon gas flow rate of 17 liters/ minute. After finishing the welding process, X-ray radiography using LORAD LPX-200 was performed in STTN BATAN Yogyakarta. Furthermore, the distortion measurements were taken using a dial indicator on the bed of milling machine. The measurement results were plotted in graph with the axis of the distance measurement vs distortion for MIG and TIG welding. The welding results showed that welding speed of 1.3 mm/ s pass the test radiography in MIG and TIG welding, and the distortion is larger on the lower speed welding. The highest value is 5 mm for MIG welding and the lowest is 0.4 mm for TIG welding. The comparison also shows that TIG welding generally cannot be conducted at high speed and by changing the order of welding in MIG, the distortion can be reduced from near 4 mm to 2 mm.

To be implementable for electronic information board, the display requires 96 × 48 pixels in minimum specification and is controlled using microcontroller. A master station located at the data center of Local Disaster Relief Agency (Badan Penanggulangan Bencana Daerah, BPBD) will transmit the data modulated using frequency shift keying (FSK) method through FM radio transmitter. Then, some work stations at the remote areas will receive the FM radio signal to be demodulated into data and further processed by microcontroller to be displayed. From the characterization, it shows that the proposed system successfully transmits the data with baud rate of 4800 bits per second (bps) with mark and space frequencies of 16.8kHz and 15.4kHz, respectively. Furthermore, bit error rate (BER) performance of the system is 0.2% which means there are 2 error bits in 1000 bits transmitted.","PeriodicalId":382919,"journal":{"name":"2017 7th International Annual Engineering Seminar (InAES)","volume":"878 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122136761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
