作者： Nurul Kusuma Delina Iis Hamsir Ayub Wahab Amal Khairan Program Studi Teknik Informatika Program Studi Teknik Elektro Fakultas Teknik Universitas Khairun Ternate Indonesia

A lot of knowledge and techniques of image processing which are now available are widely various. Much research as well as development is conducted in terms of detecting ripe fruits, one of which is chili. It is one of the local commodities that is marketable. The process of being ripe chili is relatively fast. Generally, to measure ripeness is still carried out manually. The disadvantage of this method is that the level of accuracy is inconsistent, causing fruit decay in numbers. On behalf of lowering the risk of fruit decay, the research conducted uses index pixel method. This means itself is the normalization of variety illuminated by taking ratio in each group of smallest points in an image processing. In this study, the image taking of chili using box equipped with black background is confirmed to be useful in reducing time of segmentation process. When it is in the process of detecting image by searching for the average of index pixel, then RGB will be counted using Learning Vector Quantization (LVQ) that is the calculation utilizing weighing value. As a result, the classification of maturity level can be seen in the test with a very high percentage value and influence to detect fruit ripeness, signed by the color of RG pixels (red and green) by 94.9% correctly detected, the color pixel RB (red and blue) is quite influential by 93.9% correctly detected, and the color of the GB pixel (green and blue) which was less influential at 63.6% was correctly detected.

IOP Conference Series: Materials Science and Engineering 2020年第1期879卷

作者： I Afrianto A Heryandi A Finandhita S Atin Program Studi Teknik Informatika Universitas Komputer Indonesia Indonesia.

The purpose of this research is to develop a prototype of a web-based application that can be used to provide digital signatures on files or digital documents. This prototype uses a digital signature mechanism issued by the Ministry of Communication and Information of the Republic of Indonesia (KOMINFO). The results of the research conducted by using the alpha test showed that all functionalities in the application have been able to run well. While the authentication test shows that any changes made to a document that has a digital signature will invalidate the digital signature, which means that there are attempts to falsify documents and their authenticity can be identified. This is because in documents that have the digital signature will have a certain hash value which if the document is changed or modified, then the hash value will change. This is what determines whether a document is still original or has been modified its contents, namely by comparing the hash value contained in the document.

Indonesian are carrying out routines both for personal gain, groups can use a variety of transportation in land, sea and air. Kinds of transportation that are available in the middle of the community that is affordable to have, are vehicles both two-wheeled and four-wheeled. The tendency of motorized vehicles to increase due to various factors including more economical compared to other transportation, simplify and speed up the duration of the trip, encourage the economy of the motorcycle taxi online or traditional. In the midst of people enjoying transportation, there are threats made by certain elements who take advantage of the owner's carelessness and of course the security weaknesses of the vehicle. The threat that occurs is motor vehicle thief. Based on data from the Central Statistics Agency for motor vehicle theft in Indonesia in January 2016 was 3,468 cases, February 3,595 cases, March 3,518 cases), meaning that in 2016 for three months as many as 10,581 people were disadvantaged because of the crimes. Di era industrial revolution 4.0 marked the massive implementation of information technology in all fields including transportation. Collaboration of information technology with the field of automation, in this case the workshop can create new innovations in securing motor vehicles so that they are not vulnerable to deception. The innovation is SIKEMO, works based on inputs known by the sensor, if the sensor recognizes the input data, the process can be continued and the motor can be used (starter is on status), and vice versa if the sensor does not recognize the input data, then SIKEMO will reject and of course the vehicle cannot be used ( starter in the off status). The Security System developed at SIKEMO uses data input with two models, namely the master key and the slave key. The master key input data has the highest authority besides being recognized by SIKEMO, the master key can be used to grant access rights to the slave key to be recognized by the SIK

The acquisition of 2D images of the Heroes Monument of Surabaya is a challenging task for the image-based modelling due its historical architecture complexity and structural delicacy. An effective approach of 2D acquisition is using multiple circular orbital with Unmanned Aerial Vehicle (VAV). Therefore, a quadcopter non fixed wing equipped with Global Positioning Satellite (GPS), mounted camera, and flight planning using circular orbits are the main key to take the 2D images steadily. Moreover, a field survey of preparation and observation area surroundings object is conducted to plan the part of the object that need to acquire with some details. UAV requires a plain sight to take off and frees from any obstacle which is able to interrupt UAV navigation. Thus, there are 4 phases to acquire 2D images, on every phase, they need one circle to finish and move them to other phases. While UAV loitering circle the object, the pilot manually took the 2D image. As a result, along with 80%, the overlapping of 2D images and more than 150 images have been collected, they are possible to be modeled into 3D. © 2019 IEEE.

Rindik is a traditional music instrument originated from Bali that consists of 11 bamboo rods and played by a person hitting the bamboo rod with a rubber mallet in each player's hands. Documentation of Rindik songs with automatic music transcription work is easier to do by separating it first. To overcome that challenge, two Rindik rods sound were separated using the spectral subtraction method. The noise spectrum is the spectrum of a single rod sound that needs to be muffled. The resulting audio is the other single rod sound and vice versa to get both single rod sound. The data consisted of single rod hit sound recordings of 11 single rod sound and 55 combinations of two-rods sounds being hit at the same time. The performance of the spectral subtraction method in separating Rindik sound was measured with MSE and SIR and also heard the noise exists in the separated audio signal. The experiment demonstrated a state-of-the-art performance consists of spectral subtraction with squared noise average magnitude with average MSE value 0.0126 and average SIR value 55.68 dB.

Electronic payments is something that is currently in high demand by investors today, but transactions are often constrained due to various problems, especially from third parties. For this reason, cryptocurrency emerged, which is one of the solutions for conducting electronic payment transactions. Some types of cryptocurrency that are most in demand by investors are bitcoin, ethereum, and ripple. The fluctuation value of cryptocurrency is very difficult to predict so that investors often experience losses when making transactions. This study aims to predict cryptocurrency prices such as bitcoin, ethereum and ripple using data mining algorithms. The data mining algorithm used in this prediction process is K-NN, Neural Network, SVM, Linear Regression, Random Forest and Decision Tree. Data mining modeling is done by dividing the dataset into each type of commodity and then analyzed using each algorithm. The results of this study indicate that the accuracy value obtained from some data mining algorithms is good enough to predict cryptocurrency prices
