Abstract

Rice is the most important staple food and carbohydrate food in the world especially people in Indonesia. This study aims to predict the retail price of rice in traditional markets using backpropogation by improvising Adaptive Learning Rate to increase the value of accuracy. Data sources were obtained from the Central Statistics Agency (BPS) in 33 provinces in Indonesia for the retail price of rice in the traditional market (Rupiah / kg) for the past 6 years (2011-2016). The results of the study state that the improvised learning rate uses 2 models: 2-10-1 and 2-15-1 (LR= 0,1; 0,5; 0,9) that the best architectural models are 4-15-1 (LR= 0.9) with an accuracy of 82%, Training MSE 0,000999936, Testing MSE 0.016051433 and Epoch 20515. The results of this study are expected to provide input to the government in providing input on predictions of retail rice prices that have an impact on the stability of rice prices in Indonesia.

Abstract

Searching data in the computer system by using the data search tool can make it easier for users to search for data and information. In order to make it easier for users to search for data and information, it is necessary to modify and implement several algorithms or methods to provide additional features by providing vocabulary suggestions by matching strings that can be an alternative to the search for data and information. Brute force algorithm has a way of performing string searches by randomly searching from each string to find a matching string and which will be used to perform a data search, while the steganography algorithm has a way of working to insert objects, be it in the form of characters or images. Combining the two algorithms and combining each of its performance advantages, so as to provide suggestions in the process of searching for data and information through data search. The result is brute force algorithm will search the data by shifting from each string, so in doing the data search will take a short time while the steganography algorithm performs the storage of data that has been done matching in the process of searching for data that aims to search the next data.

Abstract

Population data is information about the existence of someone in a country. The data can be accepted as validity through management in one of the government agencies. The issue of security and confidentiality of the data is something that is very important because it concerns the identity of a person, in order to avoid theft and manipulation of data it is necessary to apply a data security system. Cryptography is the study of mathematical techniques related to aspects of data and information security such as data validity, integrity, and data authentication. The Advanced Encryption Standard (AES) is one method used in data / information safeguards. The implementation of the AES algorithm in securing population data of the Population and Civil Registration Service shows that the method can produce messages that cannot be read or understood by humans (encryption) and produce the same message as the initial plaintext that was imputed (decryption)

Abstract

The Poor Student Assistance Program (BSM) is an aid from the government with the aim that poor children who excel are able to continue schooling. So that in order to minimize this assistance can be channeled properly on target, it is necessary to conduct a fairly strict selection based on the criteria that have been set. This study proposes the use of the website-based Moora method to overcome this problem. The MOORA method is very simple, stable, and powerful, even this method does not require an expert in mathematics to use it and does not require complicated mathematical calculations. The BSM assistance that will be discussed in this research is SD NEGERI 127696 Pematangsiantar City using 7 criteria, namely: Parent's Occupation, Income, Number of Dependents, Attendance, Last Semester Grades, Academic Achievement and Personality. The sample data used were 18 students. This study resulted in the highest value alternative on behalf of Ade Putri Mekaria Laila with an Optimization value of 2.22692. So it can be concluded that the Moora method can be used as a decision support method in the selection of BSM recipients.

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.
