Abstract

Very rarely the crime can be done early help or handled by the security forces while the perpetrators are still at the scene of the crime. The effort to get help from crime by reporting to the police requires a relatively long time, which is between 30 minutes to 2 hours. To reduce the number of criminal acts and early relief efforts, a tool to send short messages of crime was developed. Development of tools implements the Arduino Uno R3 microcontroller as the main component for program storage. Location coordinates are obtained from the Ubox 160n GPS module. Short messages containing biodata and location coordinates will be sent by the GSM SIM900L module. The destination number will receive a message that can be used to trace the location of the crime through Googlemaps. This tool equipped with a battery that can be recharged with a cell phone charger making this tool portable, practical and efficient. Using this Alat kirim pesan singkat tindak kejahahatan is very time efficient. The sending of a crime message is done in a very short time. By tapping the message directly the Googlemaps application opens and displays the location of the crime.

Abstract

The media is one of the supporting factors that can influence success in education. An education system that only gives lectures tends to make students get bored quickly. Even students are often sleepy when the teacher explains. As a result, the knowledge delivered by the teacher is not optimally absorbed. This proves that students tend to be interested in explanations in the form of visual images. It is hoped that the existence of a 3-dimensional animated video-based media to explain material about animal classification, especially in SMP Negeri 2 Wangon. Media itself is a component that can stimulate a person's mind so they have the desire to learn. The method in making 3-dimensional video animation, through the pre-production, production and post-production stages. In making 3-dimensional video, it explains the classification of animals consisting of pisces, amphibians, reptiles, aves, and mammals. Each is briefly explained and there are examples of each. The final results in the implementation of 3-dimensional video at SMP Negeri 2 Wangon have been successful and enthusiastic students and teachers, hoping that there will be improvements in making 3-dimensional animated videos, especially in animal modeling.

Abstract

Researches involving Artificial Neural Network (ANN) or its derivative have been published all around the world, spesifically to solve data mining problem, classification, clusterinf, or detection problems. Recurrent Neural Network is a class of ANN with Long Short Term Memory (LSTM) as its one of the architecture that commonly used in deep learning problems. On this paper, we use LSTM to detect hate speech on social media related with Indonesia President Election on 2019. There are several steps on this research, we start with literature study, data collection, data preprocessing, training step, and testing step. The dataset consist of 950 sentences, while the testing data consist of 190 comments on Facebook. The best model performance was reached with recall value 0.7021, which menas that from the whole relevant instances on the testing data, 70.21% were categorized as relevant, on this case as hate speech (HS). The other performance parameter value as in accuracy and precision still quite low due to the testing data that comes directly from social media which highly possible consist of inconsistent choises of words, informal words, or contains grammatically error sentences.

Abstract

Rice is one of the staple foods of society in general, the need for rice supply is increasing every year. The increasing population in the Jababeka area is a threat to staple food supplies. To determine the selection of Rice Brands, it takes rice criteria in order to determine the best quality of rice, and increase sales. So that it can meet consumer needs for rice. In the selection of rice brands at CV Beras Alami uses a voting system, this is clearly less valid in its election because it is subjective. Analytical Hierarchy Process (AHP) method is used as a method for decision making, as a solution in selecting rice brands in CV Beras Alami. The Expert Choice application is used as a support system to facilitate the selection of rice brands that are in demand by consumers. The results can be known during the 2018 period that rice is widely consumed is Garuda Utama.

Abstract

To understand Arabic, it is necessary to study nahwu theory. Nahwu theory is the study of structure of Arabic sentences. By learning nahwu, being able to distinguish subjects, predicates and objects in sentences. One of the fields in the computer that studies about human language processing is NLP (Natural Language Processing), which is natural human language processing through syntactic analysis of sentences structure. One method to analyzing syntactic of sentences is stemming. One variant of the stemming algorithm is Light Stemming algorithm. Light Stemming algorithm is an algorithm that only removes prefix and sufix. Based on the tests conducted, the light stemming algorithm is able to detect nahwu with an accuracy rate of 82.22%. The 17.78% failure rate occurs because words that do not have an affix will be detected automatically the type is fi’il (verb), even though the fact may be that the type is isim (noun), and the failure of the detection results is also due to not being able to stemming the words that have affix in the middle (infix), because indeed the process of light stemming only eliminates the sufix and prefix.

Abstract

Indonesian: Indonesian SIBI has been widely reviewed by researchers using different types of cameras and sensors. The ultimate goal is to produce a strong, fast and accurate movement recognition process. One that supports talk of movement using sensors on the MYO Armband tool. This paper explains how to use raw data generated from the MYO Armband sensor and extract integration so that it can be used to facilitate complete hand, arm and combination movements in the SIBI sign language dictionary. MYO armband uses five sensors: accelerometer, gyroscope, orientation, euler-orientation and EMG. Each sensor produces data that is different in scale and size. This requires a process to make the data uniform. This study uses the min-max method to normalize any data on the MYO Armband sensor and the Moment Invariant method to extract the vector features of hand movements. Testing is done using sign language Movement statistics both dynamic signals. Testing is done using cross validation.
