Published: March 2020

Abstract
Multi-Stage Flash Desalination type Brine Circulation (MSF-BC) is one of the desalination technology that utilises thermal heat in water treatment systems, which is used as a pre-treatment by purifying seawater into freshwater. In this design, MSF-BC design criteria are discussed that can meet the water needs of the 3 × 315 MW steam power plant generator with a water requirement of 130 m^3/hour. MSF-BC works with the principle of evaporation of seawater, and then the water vapour is condensed and produces distillate products. The design starts by determining the initial parameters of the design that is seawater data. Then do mass and energy balance calculations, heat transfer, and performance parameters using Performance Ratio (PR). The calculation shows that the temperature difference for each stage is 4.50 degree Celcius with a heat transfer area of 5154.2 square meter and the resulting distillate product is 131.42 tons/hour. The specifications of the pipe used are Copper-Nickel 90-10 with an outer diameter of 25.4 mm, pipe length of 2.22 m, and the number of pipes in the heat recovery stage are 2240 pieces with nine stages while in the heat rejection stage as many as 3060 pieces with three stages and performance ratio is 4.4.

K-NN based algorithm for degree of stenosis classification using dual non-invasive photoplethysmography system
Authors: Stephanus A , Du Y C 
Published: March 2020

Abstract
Haemodialysis (HD) patients who undergo long-term treatment are very susceptible to arterial stenosis. In this study, we propose two main features taken from patients undergoing the dialysis process, namely: Rising Slope – RS and Falling Slope - FS. These features are yielded from a photoplethysmography signal extraction on the hand that is used to create vascular access called HD hand. Eleven dialysis patients with the arteriovenous fistula (AVF) method were the object of this study. The feature data was taken twice, before and after the dialysis process. Utilizing the t-test on the variance of RS features on the HD hand showed a statistically significant value of 0.0211 (p <0.05). Furthermore, these RS features are used as input for KNN classifiers to classify degrees of stenosis in patients undergoing HD. Four patient data with RS features from the HD hand that was not previously known became this classifier test data. From the experimental results showed that K-NN with Euclidean and Minkowski distance could classify the degree of stenosis well. The percentage of misclassification of the system against unknown data was 18 percent (82 percent accurate) based on the cross-validated classification accuracy.

Published: March 2020

Abstract
This study presents an investigation on the role of temperature on the failure of diffusion-bonded Aluminium and Nickel. During diffusion bonding processes, where the bulk materials is subjected to join at the temperature of 300 K, 500 K, and 700 K with pressure of 10 MPa for 200 ps, the applied temperature is significantly influencing the final result of diffusion-bonded Al-Ni both in term of qualitative analysis (diffusion behaviour) and quantitative calculation (concentration distribution). In this case, as the temperature increased, the thickness of the interfacial region/diffusion zone is increased. However, when it is subjected to tensile test, the applied temperature is only has a significant impact to the ultimate tensile strength, that as the temperature is increased the ultimate tensile strength is decreased, but the applied temperature during diffusion welding is not influencing both time and strain value of the sample when it starts to failure.

Smart dunning to improve collection ratio in internet service provider using C4.5 algorithm
Authors: Thohari A H , Anita W S 
Published: March 2020

Abstract
Collection Ratio (CR) is the ratio between the total payments of all customers to the total invoice in the current month. CR is also act as performance indicator of the payment collection division for internet service companies. One method that currently used to improve CR is dunning, namely providing customer with information about the bills with various communication methods including visiting the customer’s address. Large number of customers and limited number of collectors are the major obstacle in the dunning process. We propose a classification method to predict potential delinquent customers, so that the expected accuracy of dunning increases, which in turn increases the company’s collection ratio. We use the decision tree method with the C4.5 algorithm on the historical data from one internet service provider customers in the Riau Islands province, Indonesia. The classification process produces a decision tree with 5, 885 leaves and 6, 765 tree size. The decision tree then evaluated with 10-folds cross validation that resulting in 78.54 percent accuracy, 0.738 precision, and 0.785 recall. The decision tree has been applied to the dunning process of the company.

Authors: S Atmaja I M A D , Astawa I N G A 
Published: March 2020

Abstract
A web-based application system has been widely used as an application that handles the transaction processes of a company. The problem faced a transaction web applications are cannot directly print the transaction invoice into the cashier’s printer. To print invoices from a web application, the web application must have quite a lot of supporting applications and enough configuration for the print process to be carried out. For web applications that have facilities for transactions, a technology is needed that can help users to speed up the process of transaction results in the form of transaction invoices. The technology called direct print. Direct print technology can be implemented with a supporting application such as Qz Tray. Qz Tray can help in the printing process directly from a web application that requires a print process into the transaction invoice. Configuration from Qz Tray is quite easy because the assets and coding print functions have been provided by Qz Tray directly. Asset and print function coding can be downloaded and used directly on a web application. The results of direct printing by Qz Tray can also be tailored to the needs of users so the display of invoice prints is as expected.

Published: March 2020

Abstract
The incredible growth of the internet over the past five years makes the data traffic increase significantly. When a single server gets requests from many clients, the overload will likely occur, so requests from many clients cannot be handled optimally. This results in decreased server performance. In this work, cluster implementation on mini raspberry pi computers using the load balancing method is proposed. This system used the Round Robin Algorithm in the scheduling process in each CPU queue. The implementation of server cluster consisting of Raspberry Pi with the addition of load balancing is done to overcome the limited resources on the server. When clients in the amount of 100, 200, and 500 generated by sending 1000 requests simultaneously on each test, the response times obtained are 67.3 ms, 95.3 ms, and 182.3 ms, while throughputs are 62.50 Kbps, 76.42 Kbps, and 79.62 Kbps, respectively. The results show that the responses time and throughputs are stable with Round Robin algorithm contribution. That means the Round Robin Algorithm has availability in server clustering purposes. The system promises to be an alternative server solution that is cheaper and overcomes resource limitations on the server.

Published: March 2020

Abstract
This study aims to develop a prototype system that is independent and capable of controlling TV automatically via an Android smartphone using the Arduino Uno Microcontroller. This is different from the usual TV remote where the control is limited to standby mode, the system/hardware that is built can control power on and off, so there is no electricity waste due to the TV not being watched by the owner. As it is known that the standby mode on the TV still consumes 10.96 watts of electricity. The media used for control are Bluetooth and Wi-Fi. Control with Bluetooth via an Android smartphone has 3 features which by pressing the on-off button, with voice commands and time settings, while controlling via Wi-Fi is by accessing the website. The test results show control via Bluetooth gives a response less than 1 second with a distance of less than 11 meters, via Wi-Fi gives a response of 1-4 seconds. If the TV owner has set the time the TV will be automatically controlled by the power off hardware as an assistant even though the TV owner has fallen asleep and the electricity is not wasted because the TV is still on.

Authors: Putra F P , Enda D 
Published: March 2020

Abstract
The statement of functional requirements statement that refers to software requirements specifications (SRS) is a reference for stakeholders in making software. The SRS document uses a different English grammar due to limited knowledge by the software development team, making it difficult for the development team to read and understand the specification documents for software requirements properly. To overcome this grammatical error, a method is needed to resolve grammatical errors. The method used to identify grammatical errors is based on a trigram language model. In the last research, trigram language models showed quite good performance in identifying grammatical errors based on probabilistic n-gram language models. To improve the performance of the n-gram language model this study also utilizes a corpus namely Penn Tree Bank Corpus. Provide recommendations, this study uses rules-based techniques. A number of rules are made to provide recommendations for inappropriate grammar. So that the software requirements specification compiler can check for grammatical errors and improve the quality of the software requirements specification document.
