Analisis dan Perancangan Laboratory Information Management System (LIMS) Menggunakan Metode Total Architecture Synthesis (TAS)
No full textAt present the laboratories in Colombo Yogyakarta High School have been utilized to the maximum but in the management process they are still using conventional methods and data that are not integrated either relating to administration of the laboratory, recording laboratory assets, scheduling and valuation. Recording that occurs at this time is done by using Microsoft Excel and only limited to be recorded without any synchronization and socialization to the teachers - so that it causes the use of laboratory space which is often a collision scheduling. The recording of laboratory assets is not neatly arranged so that the monitoring of assets both maintenance, replacement and repair of equipment is not well documented. This research implements the Total Architecture Synthesis (TAS) method. The total architecture synthesis method functions to determine the needs and design of business process architecture and system architecture
Komparasi Analisa Kinerja Mesh Interface Dan Bridge Interface Pada Wireless WDS Mesh Network
No full textWireless mesh networking provides a solution to the problem of network distribution that has been constrained by cable networks and wireless networks that are not directly related to other wireless networks. Some of the advantages of wireless mesh technology include extended coverages, robustness, self-configuration, easy maintenance, and low cost. Based on the problems described in the previous paragraph, this research will analyze the performance of two wireless mesh distribution methods using several topology scenarios which will later be considered to affect the quality of network distribution WDS Mesh distribution methods that will be compared in this study are WDS Mesh with Mesh Interface, and WDS Mesh with Bridge Interface. Evaluation of the two methods will be conducted periodically to get the results of the analysis which will be used to do re-configuring to maximize the features and advantages of mesh technology in maintaining reliable network quality
System Design Estimation of Cost for Laying Chicken Feed Formulation using Web-Based Square Pearson Method
No full textFeed is one important element that needs to be considered in the livestock business, one of which is laying hens. The type and amount of feed will affect the nutrients obtained, these nutrients will affect the ability to produce eggs. One way to produce feed that contains optimal nutrition is done by mixing various types of feed ingredients such as corn, bran, cake, soybeans, concentrate and so on into one right composition. Expenditures for the purchase of feed are also among the highest expenses in any livestock business and therefore need to be regulated in such a way as to provide optimal benefits. The square pearson method is a method of determining the formulation of feed which on one hand contains complete nutrients, on the other hand is economically inexpensive and easily obtained so that it can provide benefits. The results of this study produce a system that can estimate the cost of calculating web-based laying hens feed formulations
Perbandingan Algoritma Contraharmonic Mean Filter dan Arithmetic Mean Filter untuk Mereduksi Exponential Noise
No full textNoise in the image caused a decrease in image quality, so that the image will look dirty and spots appear on the resulting image. Noise also results in reduced information on the resulting image so that noise limits valuable information when image analysis is performed. Filtering technique is one way to overcome noise. The filtering technique used in this study is using the Contraharmonic Mean Filter algorithm and the Arithmetic Mean Filter algorithm with the type of noise used to reduce the Exponential Noise. The results of the two algorithms show that the Arithmetic Mean Filter algorithm is a better algorithm to reduce the Exponential Noise compared to the Contraharmonic Mean Filter algorithm which is proven based on the value of MSE (Mean Square Error) and PSNR (Peak Signal-to-Noise Ratio)
Nano Carbon-based as Supercapacitor Electrode from Cocoa Skin
No full textMost cocoa shells contain carbon which can be used as an electrode. Through nano carbon, cocoa skin has the potential to be an electrode material in supercapacitors. Nano carbon is a form of carbon that has a large surface area and pore volume. Material characteristics through FT-IR test showed that the intensity of wave absorption in the graphite group (C-C) decreased which indicates an increase in carbon. The XRD results show that carbon nano has a peak of purity close to graphite at 2θ: 24.75º on the lattice values (002). So that the nano carbon based supercapacitor electrode has an electrode resistance value of 0.0307 S/m with a specific capacitance value of 5.19 F/g
Temperature Forecast Using Ridge Regression as Model Output Statistics
No full textOver the past few years, BMKG (Meteorological, Climatological and Geophysical Agency) in Indonesia has used numerical weather forecasting techniques, namely Numerical Weather Prediction (NWP). However, the NWP forecast still has a high bias because it is only measured on a global scale and unable to capture the dynamics of atmosphere (Wilks, 2007). Hence, this study implements Ridge Regression as Model Output Statistics (MOS) for temperature forecast. This study uses the maximum temperature (Tmax) and minimum temperature (Tmin) observation at 4 stations in Indonesia as the response variables and NWP as the predictor variable. The results show that the performance of the model based on Root Mean Square Error of Prediction (RMSEP) is considered to be good and intermediate. The RMSEP for Tmax in all stations is intermediate (0.9-1.2), Tmin in all stations is good (0.5-0.8). The prediction result from Ridge Regression is more accurate than the NWP model and able to correct up to 90.49% of the biased NWP for Tmax forecasting
Melamine Processing and Mathematical Modelling of Melamine Drying in Wood
No full textMelamine wood is a coating that makes wood shiny. In this model, the Moisture Ratio formula is obtained from the melamine process. The formula is MR=a+bt, where a and b are empirical constants in drying models and values a and b depending on the ambient temperature
Seleksi Wajah Digital Menggunakan Algoritma Camshift
No full textReal time for digital face database selection using camshift algorithm] Education taken 4-5 years affects physical development. This study uses student digital video data. The recording results are used to identify certain characteristics possessed by a student later stored in the digital file database catalog. The stages of the study consisted of identification, recognition and matching of faces. It starts from converting .mp4 videos to .AVI format. The CAMShift algorithm uses basic HSV colors for tracking face position (tracking) and faces recognition. 1-2 seconds video produces 45-200 frames PNG file. The face matching test results were carried out on several video play, the success of detection: 100% selected, 45%-60%, 80-90%, concluded around 50%-100% successful. Face movements will be caught by the centroid bounding box, if the color of the face is dominant in Hue.
Pengembangan Sistem Informasi Industri Jasa Menjahit Online Berbasis Web Menggunakan Metode Waterfall
No full textInformation systems are currently increasing very rapidly, but it is unfortunate if the utilization is not yet optimal. Reviewing the data from literature studies and observations that have been made, many people need sewing services. The drastic increase in demand makes competition in the convection industry. Most of the work systems in the convection industry are done manually and are not economical. Product development also lacks creativity. Therefore, this researcher will use IT as marketing and design work, this can make processing time shorter and more optimal. Thus, customers will be facilitated in ordering ready-made clothes or clothes that match the customer\u27s wishes by using a web application that only sends data on the size of the clothes or clothing model that the customer wants. This web-based application system can make it easier for customers to transact with the owner and transactions do not have to meet face to face. In addition, clothing sales and large-scale orders can be neatly organized and financial reports can be well structured and organized clearly. The results of this research will be in the form of research reports and web-based online sewing service information systems using the waterfall method.
