In a democratic society, a citizen's ability to vote is regarded as one of the most significant legal rights he or she may exercise. For e-voting methods, blockchain presents new possibilities to properly meet transparency, integrity, anonymity and many other security properties. As the need for blockchains keeps rising, demand for bigger, more scalable, more adaptable, and more cost-effective multipurpose chain is also high. Conventional blockchains are incapable of meeting all of these demands. To solve the problems (mostly performance) associated with main blockchains, sidechain technology has recently evolved as a separate chain connected to the main chain that runs in parallel with transactions. Our proposed method is designed to operate on a public blockchain, but we separate the storage of voting information of each candidate using a sidechain to offer a cost-effective blockchain-based voting mechanism by ensuring the security properties such as anonymity, integrity, privacy, security, fairness, receipt freeness and so many. In future, we will broadly discuss and implement this voting system.

In this paper, the 3×2-cm dimension of foreign object debris (FOD) simulators is used to characterize the FOD detection. The FOD simulator used as the target is made of metal cylindrical shape. The characterization method to measure the radar cross-section (RCS) of FOD simulators at several locations is proposed. This work was conducted in a real airport runway environment at Kuala Lumpur International Airport (KLIA). Furthermore, the measurements were carried out at 93.1 GHz frequency for a Frequency Modulated Continuous Wave (FMCW) radar detection system. The backscattering characteristics of the radar target, specific design of FOD simulator, the analytical deviation and measured RCS value, and experimental procedures are presented in this paper.

In the network testing method, the use of jumbo frames that are applied in tunneling media poses problems if the communication between two points requires a large bandwidth. This paper discusses the analysis of sending jumbo frame packets that are passed through an IPv6-based tunnel using multiple Mikrotik Routers in an actual environment. The test was carried out using two different operating system platforms, i.e. Windows and Linux, by passing jumbo frame packets on an IPv6-based tunnel network using a traffic generator on a Mikrotik Router and having to go through an intermediate router. Jperf/Iperf is used for sending large and continuous data to meet the entire bandwidth capacity and to measure throughput in a network connection. The test results without using a tunnel show that a connection using MTU 4000 produces the largest throughput and takes 0.01 seconds slower, but with a throughput result that is greater than MTU 1500 bytes and MTU 9000. The packets lost when testing MTU 4000 bytes are only experienced once. In the test using tunneling, MTU 4000 produces large throughput by requiring a slightly faster transmission time of 0.01 seconds compared to MTU 1500 but there is no packet loss compared to MTU 1500 and MTU 9000. These results indicate that by using jumbo frames, the best throughput for interconnection between Windows and Linux in IPv6 tunneling based on Mikrotik Router is achieved by an MTU of 4000 bytes.

Physical layer security (PLS) is an emerging paradigm that makes use of wireless channel characteristics to provide security. Many PLS schemes require knowledge of the channel state information (CSI). However, CSI is usually imperfect due to factors such as noisy feedback channels, channel estimation errors and outdated CSI. In this paper, we investigate the impact of imperfect CSI on the secrecy and error rate performances of a PLS scheme that combines adaptive matched-filter (MF) precoding and diversity in orthogonal frequency division multiplexing (OFDM). Particularly, we derive the secrecy capacity and error rate expressions for the legitimate and eavesdropper's channels under imperfect CSI assumption. The impact of the imperfect CSI is studied via theoretical as well as numerical techniques in frequency-selective Rayleigh fading wiretap channel. The analysis is done in both frequency division duplex (FDD) and time division duplex (TDD) modes.

Water covers most of the earth's surface compared to the land, including Indonesia. Such an area can be explored using an underwater robot, which is implemented in an autonomous underwater vehicle (AUV). The AUV control system requires a controller to be able to move properly. Thus, a PID controller that has a simple structure and yields great performance can be implemented in the AUV. This study was conducted to control the movement of the surge, heave, and yaw of the AUV using the PID. The AUV modeling simulations were carried out using Simulink to determine the PID gain values. The simulation results for surge movement were Kp = 38.41, Ki = 10.8 and Kd = 58.4, heave movement were Kp = 49.13, Ki =2.56 and Kd= 107.12 and yaw movement were Kp = 3.18, Ki = 0.18 and Kd = 12.11. The results showed that AUV could perform well and maintain the position determined by the set point for 3–4 seconds.

Research in the field of autonomous electric vehicle has growth rapidly since they can overcome traffic accidents due to human error. Currently, the method used to identify the road for an autonomous electric vehicle is not in realtime. Thus, this study proposed a method for the autonomous electric vehicle to follow a predetermined route by identifying the road using the Convolutional Neural Network (CNN) as input of the steering control system. The optimal CNN model was obtained using an optimizer of Stochastic Gradient Descent with 150 epoch optimizer that was then used in simulation testing and real-time testing. In simulation testing, from 15 trials conducted, the percentage of success was 93.333%. The success rate to transmit the data from the system to the tool in a real-time manner is 100%. In real-time testing, the autonomous electric vehicle was successfully able to follow the predetermined route accurately. However, the autonomous electric vehicle has not succeeded in avoiding the object in front of it due to the lack of precise steering mechanics and the lack of variation in training data from various conditions that may be passed by the autonomous electric vehicle.

The COVID-19 pandemic is a major challenge for the global economy and gave a negative contraction in growth. In contrast to the telecommunications sector, which experienced an increase in demand for communication networks and the internet which results in making competition to provide the best service and maintain customer satisfaction. This research involved an Indonesia Telecommunication Company which is a leading company in the telecommunications industry. The Customer Experience (CX) Satisfaction Measurement report shows the company has not been able to achieve the target in managing customer satisfaction as measured using the Net Promoter Score, especially in wholesale network services. This study evaluates the company's actual business model by carrying out digital transformation in all elements of the business model through an interview process to three sources from the Wholesale and International Services Directorate who are responsible for formulating wholesale business strategies and policies. The evaluation of the business model is carried out using the business model canvas. The benefit of this research is the formulation of a new digital business model for the company, especially the wholesale segment that supports the improvement of CX for wholesale network connectivity services. The proposed business model was validated by the Wholesale and International Services Directorate. CX improvements are carried out by simplifying the company's internal processes, offering new products/services, facilitating service delivery, and increasing the main focus on exploring customer needs. The company can use this proposal as a reference in formulating a wholesale network service transformation strategy.

Batam Island is a production city that mainly connects the industrial businesses of three ASEAN countries; Indonesia, Malaysia, and Singapore. As of now, there are 17 types of industrial businesses that operate massively in Batam Island, and most of them require the Public Internet of Things (IoT) technology for their services. Therefore, it is crucial to plan a network in Batam Island that can sustain the requirements of the anticipated numerous IoT devices. This study aims to design one Low Power Wide Area Network (LPWAN) technology, namely, Random Phase Multiple Access (RPMA), to implement Public IoT services in Batam Island based on the number of sites needed on capacity and coverage planning. Furthermore, RPMA is chosen due to its ability to provide higher capacity and broader coverage than the other LPWAN technologies. This study obtained that 23 sites are needed for capacity planning, while only 15 sites are required for coverage planning. The results were then simulated using a network simulator, Forsk Atoll, to determine the best signal level received and the Signal-to-Noise Ratio (SNR) based on the most significant number of sites demanded in Batam Island. The obtained best signal level received was −69.21 dBm and SNR value of −87.87 dB. These results meet the minimum requirements for RPMA planning in Batam Island.

Accuracy in each forecasting is needed in order to find out how much error will occur from the forecasting results. The forecasting process is included in the data mining process, which is to convert data into new knowledge. Forecasting is also widely used by commodity business players such as CPO (Crude Palm Oil). CPO is a staple of human life so there is a need for a technique to increase the business. one of the things that can be forecasted from CPO is the price of CPO. By using the times series, it is possible to predict CPO prices. The accuracy measurement that can be used is MAPE (Mean Absolute Percentage Error) for forecasting. In the test, the time series data used is the average monthly yield of CPO prices starting from December 2010 to April 2021 as many as 125 data. In this article, we tested 60% of the training data and 40% of the test data, and the MAPE obtained was 0.03463929%, and the MAPE obtained with 80% of the training data and 20% of the test data was 0.04392103%. The result of MAPE does not seem that much different so that it can be tested in various other accuracy techniques

Strawberry is a subtropical fruit that thrives in Indonesia with soil as its growing media. Soil treatment becomes essential for strawberry farmers, in which the soil has a saturation nature and clump due to routine watering activity. The farmers do watering Grikulan fertilizer as a recovery step to improve soil quality. This study develops a system in the Android software or mobile application that can monitor the level of soil saturation in strawberry plants with output is the information of soil saturation indication based on the results of calculations using Fuzzy Inference System Mamdani method. The application can be connected with the actuator to water Grikulan fertilizer to give order automation. This research produces a feasibility value of 90.14% through the testing of R Validation.
