This study aims to create a system that can monitor gas cylinders where this device consists of two systems, the first is a system to measure the weight of 3kg LPG gas cylinders to find the remaining gas which will then be displayed on the LCD, and the second the system gives a notification (alarm) if there is a gas leak via SMS. This system consists of Arduino UNO Microcontroller components, Load cell Sensor, MQ-6 Sensor, and SIM800L GSM Module. For overall system testing, the load cell sensor system can display a percentage of the weight value obtained an error rate of 0%, this indicates that the formula used in the program runs according to what is desired. In the MQ-6 sensor system can make the buzzer on at a value >= 700 ppm, the results of the buzzer can live when the detected gas value >= 700 ppm, this is as desired. In the sim800L gsm module system can send leak notifications, the results obtained that the module can send SMS notifications. And the system turns on the buzzer when the LPG gas has reached the minimum limit, the results obtained by the buzzer will sound when the remaining gas value <= 16%. Based on tests conducted on this system the system can measure the desired weight of the cylinder to look for the remaining gas in the form of a percentage and detect a gas leak and then send an SMS notification.

Pedestrian Dead Reckoning

Indoor localization is one of the more accurate technologies to be used to determine indoors or buildings. Pedestrian Dead Reckoning (PDR) is a method of determining the user's position by adding a method that occurs to a known initial position. The displacement that occurs is estimated with the help of an accelerometer sensor attached to the user as a step detector and to determine the direction towards the user using a gyroscope sensor. System testing is carried out in the Institut Teknologi Sumatera’s campus environment on the 2nd floor of Building C and D. The results from the detection of steps get an error rate of 1.13% using a threshold of 0.8.

This research was conducted to create a labeling system on cardboard boxes with automatic stamping. Labeling is done based on height and weight of the cardboard so that stamping will be done according to the size and weight of the cardboard. The height of the cardboard is detected using an ultrasonic sensor and the weight of the cardboard is detected using a load cell sensor, and a stepper motor to move the cardboard label stamping. This research is based on artificial intelligence using mamdani method with fuzzy logic, so that all data can be processed properly. The height of the cardboard detected by the ultrasonic sensor is given a distance value of 10 cm to 45 cm with a value of rendah, sedang and tinggi. Cardboard weight detected by load cell sensor is given a weight value of 500 gr up to 1,500 gr with ringan,  sedang  and berat values. Stamping labels are driven by stepper motors which are given time values ​​of 5 s to 15 s with time values ​​of  sebentar, sedang, and lama After the ultrasonic sensor and the load cell detect the cardboard box, the conveyor belt moves to run the cardboard box by the power window motor, then if the cardboard box passes through the proximity sensor, the conveyor belt stops and the stepper motor moves to stamping the cardboard label box automatically. The label stamping system is controlled by using the Arduino Mega 2560 to work well.

Neural networks have recently been applied to real-world speech recognition problems with a great deal of success. This paper develops a strategy for optimising a neural network known as the Radial Basis Function classifier (RBF) on a large spoken letter recognition problem designed by British Telecom Research Laboratories. The strategy developed can be viewed as a compromise between a fully adaptive approach involving prohibitively large amounts of computation and a heuristic approach resulting in poor generalisation. A value for the optimal number of kernel functions is suggested and methods for determining the positions of the centres and the values of the kernel function widths are provided. During the evolution of the optimisation strategy, it was demonstrated that spatial organisation of the centres does not adversely affect the ability of the classifier to generalise. An RBF employing the optimisation strategy achieved a lower error rate than Woodland’s multilayer perceptron26 and two traditional static pattern classifiers on the same problem. The error rate of the RBF was very close to the estimated minimum error rate obtainable with an optimal Bayesian classifier. An examination of the computational requirements of the classifiers illustrated a significant trade-off between the computational investment in training and level of generalisation achieved.

The conversion of kerosene use in household to gas, in addition to the decision of the Republic of Indonesia minister in relation to the movement of kerosene to gas, gas also given an affordable price, how to use it more effectively. But the public is also expected to be careful about how to use it, because the gas is explosive and leaking causing unpleasant odor (gas leak) even a more dangerous side effect is the explosion of gas cylinders. To evercome these problems then need a tool that can detect gas leakage, in order to prevent gas leakage early. Therefore the authors designed a device that can detect gas leakage by using Sensor Mq-2 and will issue sound gas alarm warning leak by Modul ISD 1760, and will stop the gas flow from the tube to the stove using a Solenoid Valve. There is also a Flame Sensor’s hardware to detect a fire if there is a spark emerging and spraying water into spots that are likely to spark fire. All hardware will be in if using ATMega 328microcontroller.Monitoring can use android smartphone, with the application that can send a warning to the mobile phone.

Fiber optic is chosen to be the backbone channel for telecommunication purposes, in this case the connection between nodes b. Therefore, to determine the performance of a fiber optic network, a fiber optic communication network performance application is required. The performance discussed in this study is total attenuation, Optical Signal to Noise Ratio (OSNR) and Bit Error Rate (BER). The method used to obtain the attenuation value along the length of the cable and the total attenuation is by measuring the fiber optic network with an Optical Time Domain Reflectometer (OTDR). After taking measurements, the data is processed to produce output in the form of network performance, namely the total attenuation value, OSNR and BER. The results of the accuracy of the two comparisons are indicated by the percentage error rate. Based on the overall data tested, a value of 5.53% was obtained for comparison between the theoretical results and the value of the measurement results and obtained a value of 5.10% for the comparison between the measurement value and the application calculation value. Then the relationship between total attenuation with OSNR and the relationship between OSNR and BER is an inverse relationship.

Third Fleet is the Main Command of the Indonesian Navy as Operation City which is tasked with carrying out defense and security operations of the maritime dimension by securing the territorial waters of eastern Indonesia. The operation in these waters is faced with the vulnerability of frequent violations, geological conditions consisting of thousands of islands and shallow straits, extreme weather and also with limited state defense budget conditions. Therefore, it is very necessary to have a KRI that is right and ready to face these challenges and obstacles so that the goals of the organization can be achieved. The purpose of this study was to analyze the criteria and determine the type of KRI needed in accordance with the conditions in Third Fleet. This study uses an integration between the Delphi method and the AHP method. The results of this study are expected to be input and consideration for the leadership of the Indonesian Navy.

AbstractExistential types provide a simple and elegant foundation for understanding generative abstract data types of the kind supported by the Standard ML module system. However, in attempting to extend ML with support for recursive modules, we have found that the traditional existential account of type generativity does not work well in the presence of mutually recursive module definitions. The key problem is that, in recursive modules, one may wish to define an abstract type in a context where a name for the type already exists, but the existential type mechanism does not allow one to do so. We propose a novel account of recursive type generativity that resolves this problem. The basic idea is to separate the act of generating a name for an abstract type from the act of defining its underlying representation. To define several abstract types recursively, one may first ‘forward-declare’ them by generating their names, and then supply each one's identity secretly within its own defining expression. Intuitively, this can be viewed as a kind of backpatching semantics for recursion at the level oftypes. Care must be taken to ensure that a type name is not defined more than once, and that cycles do not arise among ‘transparent’ type definitions. In contrast to the usual continuation-passing interpretation of existential types in terms of universal types, our account of type generativity suggests adestination-passinginterpretation. Briefly, instead of viewing a value of existential type as something that creates a new abstract type every time it is unpacked, we view it as a function that takes as input a pre-existing undefined abstract type and defines it. By leaving the creation of the abstract type name up to the client of the existential, our approach makes it significantly easier to link abstract data types together recursively.
