Abstract
Retinal blood vessels are a very important object to diagnosing illness. Fast, automatic, adaptive, and accurate systems to segment the retinal vessels are particularly useful. The retinal blood vessels can be detected by edge detection. This research will compare the edge detection techniques with adaptive ant colony optimization (Adaptive ACO). Generally, the early ants on the conventional ant colony optimization (ACO) are randomly distributed. This condition can cause the ant distribution imbalances. Based on this problem, the ant distribution modification on ACO is proposed to optimize the ant placement based on the gradient. The gradient values are used to determine the ants’ placement. The ants are not randomly distributed but placed in the highest gradient. The so-called Adaptive ACO is expected to be used for better and faster path discovery optimization. The average PSNR of Prewitt edges, Sobel edges, conventional ACO, and the proposed method are 11.605, 11.913, 9.783, and 15.874 respectively. The PSNR of the proposed method has the greatest value than others. It shows that the placement of ants based on gradient can improve edge detection accuracy. The application of the Adaptive ACO method has successfully optimized the result of retinal vessel edge detection.

Abstract
The calculation of ship operating costs is a major element in determining tariffs. The determination of high or low tariff is very important in the shipping business. In other words, determining the proper ship operating costs is the key to the success of the shipping business. There are several components in determining the operational costs of a ship, one of which is the calculation of fuel needed to cover a certain distance. Usually for new routes, the calculation uses the formula specified by the Minister of Transportation No. KM. 58 of 2003. However, this manual calculation requires a lot of time and human error factors will result in inaccurate calculation results. So, we need a more effective and efficient way to calculate the amount of fuel needed to cover a certain distance. In this study, a simulator was developed that uses the concept of a spherical triangle to determine the distance and direction of a ship and then integrates it with the formula of the Minister of Transportation to get the results of the fuel calculation. From the results of 2 trials using the Bung Tomo Training Ship, the calculation results were faster and more accurate. Even more, the simulator users can simply click two points as the beginning and end of the ship’s journey. Thus, the simulator can simplify the process of calculating ship operating costs, especially the determination of new routes in the shipping business.

AbstractAt this time, social networking is becoming a very popular communication tool among Indonesians ranging from children to adults. One of them is Twitter, which has quite a lot of users. This social network is used by users to write their opinions on a matter. One of the topics discussed in the Twitter social network is the Trans-Jakarta bus. In this study, the opinions of Trans-Jakarta bus users listed on Twitter are only limited to positive and negative opinions. An application designed to predict positive or negative opinions using the Naïve Bayes algorithm. The Naïve Bayes algorithm was chosen because it only requires a small amount of training data to estimate averages and variable variations. The developed application can make it easier for decision-makers towards Trans-Jakarta to find out public opinion on Trans-Jakarta bus services. The resulting system accuracy is 73% because the amount of training data used is only 62.5% of the total data of 50 data. While the test data that has been used are only 30 data. The proportions of the training and testing data affect the level of accuracy, so if you want a higher level of accuracy you can reproduce the training data used.

Abstract
Fly ash (FA) is burning coal product which is used as supplementary cementitious materials (SCM) as the conjunction with cement. The use of FA is considered by its pozzolanic properties i.e. SiO2, Al2O3 and CaO to hardened concrete. The potential of FA as SCM has been well-known over the globe but that significant utilization has to be studied based on its compound’s characteristics and pozzolanic activity. For this case, the amount of FA is added 30% by mass of total cementitious material, concrete with fly ash (NFA) and another blended without FA as normal concrete (NC) made of ordinary Portland cement. This amount is indicated as dosage in moderate to high volume of FA classification. This replacement pairs with water to cement ratio (W/C) with the value of 0.47 and 0.30 e.g., NC1, NC2 and NFA1, NFA2, respectively. These W/C uses considering effect FA on water demand of concrete proportioned for equal slump. The results showed that NC2 and NFA2 in the age of 28-day inform higher compressive strength, 30% and 28%, respectively. Another indication from the comparison of NC2 and NFA2 were also in good agreement that the use of FA decrease the compressive strength around 3% to 6%.

Authors: Asdi R , Basuki M 
Published: January 2021

Abstract
This paper presents a method for risk management applicable in shipbuilding projects. We focused this study specifically to assess delay in project completion by analysing the production processes. The production processes were grouped into three major parts, namely the work of design, material procurement, and production processes. Risk data were collected from risk documentation of fast patrol boat constructions in PT. PAL Indonesia (the company). Bayesian network was used to assess the probability of project completion delay. Noisy-OR canonical model was used to define parameters needed for the Bayesian network model. Based on the current condition, the Bayesian network model predicted that there is a probability of delay of 0.67761739 that the project completion will be delayed. The Bayesian network model was also used to assess mitigation actions to reduce the probability of delay. Three mitigation action sets were provided based on the complexity of mitigation action: (1) less complex mitigation action, (2) more complex mitigation action, and (3) most complex mitigation action. The Bayesian network model predicting that the most complex mitigation action would provide the best result in mitigating the project completion delay.

Published: January 2021

Abstract
In this study, electrospinning technology, iodine treatment, thermal stabilizing, and carbonization processing were applied to produce lignosulfonate-based carbon nanofibers. The porous structure of the produced lignosulfonate-based carbon nanofibers primarily contained mesopores and a relatively small amount of micropores. Moreover, the increasing amount of sodium lignosulfonate (SLS) as lignin source was also studied. The diameter of fibre was impacted by the additional of SLS that may cause by the alkali content of SLS itself. In electrospun nanofiber phase, the presence of SLS reduce the specific surface area, but contrary increase the specific surface area after the nanofibers were carbonized into carbon nanofiber. Lignosulfonate-based activated carbon fibres can be used as a highly efficient adsorption and filtration material, and further development of its applications would be valuable.
Effect of hole diameter and basin size on the vortex gravity system
Authors: Herbhakti F A , Hantoro R 
Published: January 2021

Abstract
The vortex gravity system consists of a tube basin, a canal (worksection) and a water tank. Water is pumped into the upper tanker and flowed into the canal by opening the valve which then hits the tube basin and creates a whirlpool. The water that hits the tube and enters the outlet hole goes down to the lower tank and is circulated back to the upper tank. The outlet hole in the tube has 4 sizes and the tube size has 3 sizes. This study is based on experimental tests to determine the flow performance of the outlet diameter of the tube against the formation of vortices in the vortex tube. From several existing studies, the type of outlet hole in this tube has not been thoroughly studied. From the analysis results, it can be seen the difference in the results of each outlet size in the tube basin. With this question, this study aims to determine the strength of the vortex of the parameters that must be looked for, namely Water Flow Discharge (m3 / s), velocity (m / s), and Total Head Water (m). The vortex gravity system on a laboratory scale, based on previous studies or studies varying the diameter of the vortex tube and tube outlet hole, this study examined the effect of differences on the diameter of the vortex tube and the outlet hole of the tube basin. From the calculation of the vortex strength at the outlet hole of 25 cm, the results of the vortex strength are 7.53 m2 / s; 22.60 m2 / s; 45.21 m2 / s; 52.75 m2 / s. After that, proceed with the calculation of the outlet hole of 30 cm, the results of the vortex strength are 12.24 m2 / s; 28.26 m2 / s; 45.21 m2 / s; 56.52 m2 / s. Furthermore, the calculation at the 35 cm outlet hole obtained the vortex strength of 14.13 m2 / s; 30.14 m2 / s; 42.39 m2 / s; 60.28 m2 / s. the occurrence of fluctuation in the vortex strength results due to the energy available in the extracted water flow after hitting the outlet hole in the vortex tube. The graph produced in this calculation shows that the highest vortex strength occurs in a tube with a diameter of 35 cm.

Authors: Rajpoot Prince , Dwivedi Pragya 
Published: January 2021

Abstract
It is the digital era that provides importance for the research in Wireless Sensor Network (WSN). Different issues with different solutions are suggested by many authors. The realistic deployment having restrictions for cost, area coverage, Cluster Head (CH) coverage, and sink connectivity for WSN that demands an estimation of total count of sensors for deployment with the conditions for CH coverage and sink connectivity. Area coverage means how much portion of total area is sensed by deployed sensors nodes. CH coverage means the sensor node is able to transfer the sensed data to its CH without amplification and sink connectivity means that the CHs are connected with the sink and able to send the data directly without amplification. AHP is a Multi Attribute Decision Making (MADM) method that is used for the selection of best choice having less cost and efficient coverage and connectivity.

Published: January 2021

Abstract
This paper examines the status of Information Communication and Technology (ICT) in the state of Nagaland by using well-structured questionnaires and secondary data. The study had analysed the benefits and challenges of ICT covering the entire state. It is observed that although ICT had picked up well, there are many places especially in rural areas where ICT usage is still very low. There is no doubt that the use of ICT is contributing a lot to the uplift of socio-economic of the people but there is also a necessity of further improving the electronic public service delivery to citizens in a transparent, efficient, cost-effective and easy manner. In general, it is seen that the younger generation appears to be much more in favour of engaging ICT tools in their day to day work and while framing ICT policies more focus have to be given on the lower age groups so as to improve trust between citizens and government and between citizen and various institutions. The study also reveals that sincere efforts have been made to use the latest state of art technologies to take the state of Nagaland to the next higher level and the state is now fully aware of the benefits and challenges of ICT. The findings of this study shows that placing more emphasis on ICT can significantly speed up the overall inclusive socio-economic growth of the state and therefore more initiatives have to be taken to strengthen ICT so as to bring quick changes in governance and all other spheres of life.

Authors: Hussain Md. Anwar , Gogoi Lakshipriya 
Published: January 2021

AbstractAmong various lung image modalities, CT (computed tomography) images have been found most suitable and widely used for detection of small lung nodules. Although an expert radiologist can analyse these images quite perfectly, however an efficient CADe (computer-aided detection ) system capable of detecting pulmonary nodules automatically may be of great help considering the large number of CT images, a radiologist needs to analyse a day in recent years. A few CADe systems have already been tested within lung cancer screening trial which have enjoyed mixed results. So, the field has enough voids to be filled and research towards development of novel and efficient CADe systems has become an interesting, but challenging field of research. We too have been trying to develop CADe systems that can analyse CT images to detect and identify various lung nodules. In the process, we are reporting herein one of our development for the same. Our CADe system has maintained its 81.25% accuracy in detecting malignant nodules. Hand-crafted features of the selected lung CT images were used in the study. The study is emphasised on developing efficient CADe systems capable of detecting solid nodules (size > 2 mm) at different locations, whether isolated, juxtapleural or juxtavascular nodules. While MATLAB was used to carry out pre-processing, segmentation and nodule detection, testing of datasets was done by a MLP (multilayer perceptron) network by using WEKA (Waikato Environment for Knowledge Analysis) software.
