Perancangan Pengontrolan Overhead Crane Menggunakan Kabel dan Nirkabel Berbasis Arduino
Get PDFOverhead Crane is a heavy equipment which is very much found in various industries, factories, and workshops that are used to transport material. In general, controlling the Overhead Crane is operated by using a Push Button that is hung together with a cable on the top frame of the Overhead Crane. in this case, humans must also be able to maintain a distance when controlling Overhead Cranes that are working to transport memterials to avoid the use of Overhead Cranes. To provide security and comfort in the use of Overhead Cranes, the authors designed an Overhead Crane controller using Arduino based cable and wireless. The design of Overhead Crane control using a cable consists of several series of Push Button arranged in a plastic box and then hung on the side of the Girder Crane. for the input foot the Push Button is given a voltage 12 VDC, while the output of the Push Button is connected with contact points of the Relay 12 VDC to execute electrically mechanical Overhead Crane. While the Overhead Crane control design using wireless consists of several components, including: Arduino Mega 2560 which is combined with USB Host Shield. Bluetooth csr 4.0 Dongle is connected to the USB Host Shield port for data communication media between Arduino Mega 2560 with Bluetooth Joystick PlayStation 3 (PS3). The signal pin of the Relay modules is connected with Arduino Mega 2560 pins according to the program designed. Contact NO points Relay modules are connected with 12 VDC Relay point contacts to execute electrical mechanical Overhead Crane
Pengetahuan Wisatawan Mancanegara atas Kehadiran Patung Garuda Wisnu Kencana sebagai Ikon Pariwisata Indonesia
Get PDFIn 2018, Indonesia has a new tourism icon, namely Garuda Wisnu Kencana Statue, which located in Bali, the most famous tourist destination in Indonesia. The presence of this tourism icon is certainly expected to support increasing numbers of tourists to Bali and Indonesia, especially for foreign tourists. One year has passed but there still no tourism improvement from the presence of this tourism icon, there are no major activities that can invite tourists to visit and there is no research on this tourism icon. Therefore, descriptive research was conducted by distributing questionnaires through online media to foreign tourists from five continents in the world to find out whether foreign tourists knew about the presence of the Indonesian tourism icon Garuda Wisnu Kencana Statue. The results of this study show that 87.5% of respondents from 28 countries in various parts of the world did not know about the presence of this new tourism icon, and of course, there was no significant impact resulting from the tourism icon. The low level of knowledge of the presence of tourism icons surely related to the marketing method both carried out by the local tourism government and the central tourism government. Discussion of marketing methods certainly requires further complete research but the results of questionnaires show that according to respondents one of the best marketing media to promote a new tourism icon is social media and the internet/website.
Pemanfaatan Limbah Kulit Singkong untuk Produksi Oligosakarida melalui Hidrolisis Kimiawi
Get PDFCassava peels are biomass wastes that is rich of polysaccharides. Polysaccharides can be hydrolyzed chemically under control to produce oligosaccharides. The aims of this research are to study the suitability of the type of acids and the concentration of acids to hydrolyze, and analize the hydrolysis product using spectrophotometer and thin layer chromatography (TLC). The acids used in the hydrolysis were chloride acid, sulphuric acid, phosphoric acid, acetic acid, and citric acid, in concentration 0.3; 0.4, 0.5; 0.6; 0.7 molar. Total sugar was determined using phenol method. Analysis of reducing sugar was performed by the DNS method. The ratio of total sugar to reducing sugar was used to predict the degree of polymerization (DP). Almost all of acids with each concentration produced DP 2-6. The results were also confirmed using TLC and the retardation factor (Rf) compared using glucose and maltose as relative standards.Keywords: cassava peel waste, oligosaccharide, chemical hydrolysi
ANALISIS GEOMETRI HASIL BORING ID EYE ROD AS REAR SUSPENSION 777 PADA MESIN HORIZONTAL MILLING CNC HAAS EC1600
Get PDFThe repair process Rod As Rear 777 Suspension in PT.SSB one of them is the id eye repair process. The work of boring id is the process of enlarging the desired size hole and usually does not pay attention to the geometry deviation from the boring process, even though it is very influential with the quality of machining results. The research objective is to find out the geometry of the results of boring id bore Rod as Rear Suspension 777 on Horizontal Milling CNC Haas ec1600 machine. The independent variables in the study were cutting depths of 1 mm, 2 mm, 3 mm, spindle rotation 300 rpm, 400 rpm, 500 rpm. The dependent variable is the geometry deviation resulting from boring id bore Rod As Rear Suspension 777. The control variable is the CCMT 120408 tool, feed speed 0.1 mm / rev, diameter of eye 158 mm, coolant damin water and ecocool 2700T. The measurement method uses a bore gauge / cylinder gauge to determine the effect of variations in machining parameters on boring geometry with a tolerance of ± 0.02 mm and takes 4 measuring axes namely X, Y, X ', Y'. From the research that has been done that the parameters with the smallest geometry deviation obtained at the cutting depth (ap) 1mm and spindle rotation (n) 500 rpm, is the expected result because the geometry deviation is 17µm still within the tolerance limit of ± 0.02 mm. The greater the value of the cutting depth (ap), the greater the geometry deviation that occurs. Whereas the greater the cutting speed value (Vc), the smaller the geometry deviation will occur

Modal Intelektual, Budaya Perusahaan dan Kinerja Keuangan pada Sektor Perbankan Indonesia
Get PDFThis study examines whether intellectual capital and corporate culture affects financial performance in Indonesia. Data are drawn form 34 sample of publicly bank that listed in Indonesia Stock Exchange (IDX). Intellectual capital using VAIC method and the four type of corporate culture (collaboration oriented/COL, control oriented/CON, competition oriented/COM, dan creation oriented) using ATLAS.ti following the bag of words by Fiordelisi & Ricci (2014). We find evidence that intellectual capital, collaboration oriented - culture (COL), creation – oriented culture (CRE) are positevely related to financial performance. Competition – oriented culture (COM) is negatively related to financial performance, while the last type of corporate culture: control – oriented culture (CON) is not relayed to financial performance
