Abstract

Venereal disease is a disease that strikes in the genital organs of male or female which usually brings in through sex or oral sex. Venereal disease has long been scattered in several countries, one of them in Indonesia. Venereal disease has become so important that discussion after the AIDS disease cases arise which cause a large number of victims died. Venereal disease can be transmitted from one person to another through sexual contact. In Indonesia, the sexually transmitted disease that is most widely found is syphilis and premenstrual syndrome, the prevalence of sexually transmitted diseases in Indonesia is very high in Jakarta found prevalence of premenstrual syndrome 29.8% 25.2% and syphilis, chlamyd He was 22.7%. Tsukamoto Fuzzy method is a method that has a tolerance on the data and very flexible. The advantages of the method are namely Tsukamoto is intuitive and can give feedback based on information that is not accurate, qualitative, and ambiguous. On the methods of Tsukamoto, each Rule is represented by a set of Fuzzy membership functions with a monotonous called fuzzifikasi. As a result, output the result of each Rule in the form of value of the firm (crisp) based on α-predicate or the minimum value of each Rule and the value of z. end result is obtained by performing a weighted average defuzzifikasi. In this research the required variable is a list of symptoms and venereal disease in men is accompanied by a weighted. This research resulted in an average accuracy rate of 81.67% system.

Abstract

Technology developments demanded cutting-edge data security systems, especially on hardware systems. NIST (National Institute of Standard Technology) is an institution that oversees data security standards. NIST organized an eSTREAM project to search for new stream cipher algorithms for various hardware and software application profiles. The algorithm chosen for hardware is the grain algorithm. Grain algorithm is superior because the architecture has a complex level of complexity so that the level of security is higher. The algorithm has two versions v1 and 128 bit. This research tells how to use grain algorithm to secure data on hardware side applied to arduino mega. Researchers chose arduino mega due to the use of this microcontroller in the IoT and there is no update data security using the latest stream cipher. Conducted 3 stages of testing that is validation test vector, performance analysis between grains through the execution time keystream and data encryption and decryption. This research yielded keystream validation in accordance with test vector. The results were analyzed using Independent t-test statistic test, with the result of Sig's keystream execution time. 0.662 then there is no significant difference in the performance of grain algorithm v1 and 128. While the results of the execution time of encryption and decryption of both algorithms also have no significant differences, indicating that arduino mega has a stable performance in running both algorithms.

Abstract

Siltation caused by erosion of soil in river is also a constriction caused by existence of illegal buildings built in watershed. This condition causes water capacity of river smaller, causing river overflow and flooding occurs. Use ultrasonic sensors as water level detection can done to determine increase water level in river. Sending one data to one computer becomes ineffective because the number of devices required. Point-to-point routing method can be a solution to solve problem. Through this method, user doesn't need to monitor one data from one node. River height data will sent by nodes to gateway so that only requires one device connected to computer. This research implements point-to-point routing as communication method of river water level detection system using nRF24L01 communication module. The system designed to transmit obtained data by node to gateway. Gateway will receive data from node, then program will created display in graphical form. From the results of tests conducted level of accuracy of ultrasonic sensors more than 89%. The data reading on the prototype has an accuracy 80%. Data delivery has 100% accuracy.

Abstract

Bogor Botanical Garden is one of the botanical gardens in Indonesia that is managed directly by the Plant Conservation Botanic Gardens-LIPI which has an area of 87 hectares. There are various types of plants and attractions in Bogor Botanical Garden. With the vastness of land owned, there are several problems that are felt by Bogor Botanical Garden's visitors, they are: the visitors do not know the location of the attraction to be visited, the visitors do not know the diversity of attractions, and the visitors do not know how to give a testimony to the manager. So far, the manager finds out the satisfaction level of the visitors simply by seeing visitor posts on the Bogor Botanical Gardens Facebook Fanpage page which is considered to be less valid in representing the satisfaction level of the visitors. So, a solution given to overcome these problems is by adding features to search the location of the attractions in the Bogor Botanical Garden, to display the list of tourist attractions, to save testimonials and to display a graph of visitors' satisfaction results from image detection using the Local Binary Pattern (LBP) algorithm. The result of the tests shows that unit testing, integration testing, and validation testing is 100% valid and the result of compatibility testing shows that the system can run on 8 types of web browsers.

Abstract

Fault tolerant is needed because many systems are in conditions such critical systems, prone to damage environment, complex designs, and systems with variety users. The survey results of IT company said 99% of 400 respondents had experienced system failure caused by hardware damage resulting in data loss. To overcome this problem, a fault tolerant system was implemented on the hardware part (hardware redundancy) using N-Modular Redundancy (NMR) method that was applied on intensity and temperature reader system. NMR work by duplicate hardware as N that works together and get the same input and then the output results are determined by voting logic using majority vote. The object of implementation is intensity sensor BH1750 and temperature sensor LM35 as input, Arduino Uno as a sensor reader and voter, and the output will be displayed in the Arduino IDE serial monitor. The redundant hardware is sensor reader, Arduino Uno. The test results showed that the system more reliable because even though one of the redundant modules was damaged, the system still operate properly from the other redundant modules that running normally. The analysis before and after the application of the TMR method, reliability system increased by 9.2% from 83.51% to 92.7%.

Abstract

Diabetes Mellitus is one of the diseases with the highest number of casualties in Indonesia. The high diabetics in Indonesia are due to the lack of public knowledge about healthy food controls that result in poor diet. As a result, many people have not met the balance of nutritional intake that is the most important part in managing a good and healthy diet. Information on the right diet is needed for diabetics to improve their health condition. The Particle Swarm Optimization (PSO) algorithm is often used in performing optimization cases with good and optimal results, in particular, there is development to Improved Particle Swarm Optimization (IPSO) which further improves PSO performance. Therefore, this study designs an optimization system for the composition of food ingredients for the nutritional needs of people with Diabetes Mellitus using Improved-PSO algorithm. The results obtained from this study are optimized Improved-PSO parameters that are population number = 150, acceleration coefficient value = 2, 1, and convergent system on iteration to 550. In addition, from the results of global analysis shows that the nutrient calculation of the system can meet the nutritional needs of patients with a difference of tolerance ± 10% of expert calculations.
