Abstract

Compression is a reduction in the size of the data to a smaller size than the original. The technique of compression is to replace the repetitive character with a certain pattern so that the data can minimize its size. Therefore the data that will be stored needs to be compressed first so that the size becomes smaller. The advantage of pdf files is that the pdf file format can not only store data in text form but also can save an image (image) or photo. In storing in pdf files, the data that will be stored is not susceptible to viruses. One pdf file compression technique that can compress images well is compressing pdf files using the J-Bit Encoding method. J-Bit Encoding (JBE) is an algorithm that optimizes input for other compression algorithms, thus the compression algorithm will be better if it is combined with the J-Bit Encoding method.

Abstract

Indonesia has a high biodiversity of snakes. Snake species that exist throughout Indonesia, consisting of venomous and non-venomous snakes. One of the dangers that can be posed by snakes is the bite of several types of deadly snakes. Snake bite cases recorded in Indonesia are quite high with not a few fatalities. Most of the deaths caused by snakebite occur due to errors in the handling procedure for the bite wound. This problem can be overcome one of them if we know how to classify snake bite wounds, whether venomous or non-venomous. In this study, a classification system for snake bite wound image was built using Regionprops feature extraction and Decision Tree algorithm. Snake bite images are classified as either venomous or non-venomous without knowing the kind of the snake. In Regionprops several features are used to help the process of feature extraction, including the number of centroids, area, distance, and eccentricity. Evaluation of the model that was built was found that the parameters of the number of centroids and the distance between centroids had the most significant influence in helping the classification of images of snakebite wounds with an accuracy of 97.14%, precision 92.85%, recall 91.42%, and F1 score 92.06%.

Abstract

In this day and age many people use the internet with wifi media because its use is easy and efficient, in contrast to the use of network cables because of its inefficient use and consuming a lot of space. But now the use of wifi is widely accessed by unauthorized people to access it and insecure login verification process and the amount of access that uses wifi on one SSID will result in a decrease in internet speed on wifi, to enter and verify it into a wifi network. text and numbers or security using the QR Code. Using a QR Code or an ordinary password will not be able to deal with people who are not entitled to such access, so it needs layered security to secure and verify wifi logins from people who are not entitled to access them. Base64 algorithm is one of the algorithms for encoding and decoding a data into an ASCII format, which is based on basic numbers 64 or can be referred to as one method used to encode binary data. In securing wifi by verifying the QR Code login wifi network using the base64 algorithm makes using wifi can be overcome and handled so that no one breaks into the wifi network because it can harm the users or owners of the wifi network

Abstract

At crossroads, both crossing three and crossing four which have traffic lights, there is often heavy traffic. Of course this can hamper the performance of priority vehicles that will cross the intersection. To overcome this, the researchers designed a traffic light microcontroller system using a sound sensor. Sound sensor is an automatic identification technology that uses sound waves that hit the sensor membrane which causes the sensor membrane to move which has a small coil behind the membrane up and down then the sensor will be connected to the lights at each airport parking road junction so that the traffic lights of the parking area and arrival terminal or the release changes automatically. The purpose of this study is expected to produce a traffic light system design that utilizes IOT sound sensor technology to the density of vehicles that are at a crossroads either intersection three or intersection four in order to regulate the smooth flow of vehicles and things emergency vehicles (ambulances, fire engines or officials) can work on time and at the maximum, The output produced is a prototype IoT product and publication to journal

Abstract

The Water Resources Management Agency has the main duty to organize some district government affairs in the field of water resources management based on the principle of autonomy which becomes the authority, deconcentration and assistance duty and other tasks in accordance with the policy stipulated by the Regent based on the applicable laws and regulations. The performance appraisal undertaken in this agency is intended for the Civil State Apparatus. the assessment process is carried out for measuring and improving the performance of the State Civil Apparatus so as to encourage these employees to work better. From the assessment of the superior can be determined the best employee or promotion position. The performance appraisal process conducted by the culture and tourism office is still done manually, so the performance calculation tends to be subjective and takes a long time. Therefore, in order that the process of appraising employee performance becomes more objective and practical, it should be done computerized by developing an application that implements the right methods. This subjectivity can be overcome with decision support system using Simple Additive Weighting (SAW) method based on existing assessment criteria. The end result of research is the rank of employee value that can be a consideration for decision makers in the determination of promotions as well as an encouragement for employees to work better and productive.

Abstract

A protective tree is a group of plants that have long canopy and thick leaves and trunk high enough to be a shade. Usually a protective tree becomes the main plant in a park. But what we often see is the protective tree planted along the road. Its function aside from being a shade tree is also intended to absorb pollution. It is necessary to determine the selection of the best tree species to be planted on the side of the road. The selection of protective tree species still uses a manual system and requires quite a long time. Based on these problems, we need a decision support system (SPK) that can facilitate the selection of the best protective tree species using existing criteria. One method that can be used is the Preference Ranking Organization Method for Enrichment Evaluation II (PROMETHEE II). This method is able to solve any type of problem in decision making with alternatives and criteria that have been given weight. Research using PROMETHEE II produces the composition of the usual protective trees to the best protective trees. The protective tree selection system was built using Microsoft Visual Studio 2008 and Microsoft Access 2010 as a database.

Abstract

Songket is a traditional Malay and Minangkabau woven fabric in Indonesia, Malaysia and Brunei. Songket is classified in the brocade woven family. Songket is hand woven with gold and silver threads generally worn at official occasions. The purpose of this study is to analyze the texture of songket fabric by using gabor filters. The results of the study stated that the texture output that appeared was strongly influenced by the magnitude of the frequency parameter values and the orientation of the image degrees. The greater the frequency value given, the results of the test use look brighter and blurry. Therefore the frequency value on the middle scale (f = 0.176) is considered the most appropriate for texture analysis. In addition to the frequency of orientation parameters are also able to show a tendency towards the texture in a certain direction. From the appearance of this fabric texture, the area suspected of having a good texture on the songket cloth.
