Gas hydrate is a type of hydrocarbon formed like crystals and is formed in the seabed sediment layer. Water temperature and pressure affected the area where gas hydrates are formed; gas hydrates are composed of gas and water elements. Gas hydrates have the potential as an alternative to current uses of oils and gasses. The identification of gas hydrates on the seabed can be detected using low-frequency acoustic, seismic technology. This research aims to identify the presence of gas hydrate in Aru Sea waters based on changes in the seismic character of the gas hydrate. The method used is seismic data processing with ProMAX software. This research uses seismic data for the 3.01 trajectory acquired by the Marine Geology Research and Development Center in 2016 in the Aru Sea. Based on the data processed, gas hydrate was detected on the 3.01 line with a depth of 5,925 meters. Gas hydrate indicator on the seabed is characterized by cutting stratigraphy, reversing its polarity, high amplitude, and shape following the seabed.

A Bluetooth was developed as a means for short-range communications. However, the limited range of Bluetooth devices that tend to be narrowly led to the use of Bluetooth is less developed. Whereas, with its properties, sharing of data should be done easily and cheaply. This research has designed a transceiver antenna for Bluetooth communications that works at a frequency 2.4 GHz ISM-band. The antenna is designed in the form of a microstrip antenna with Complementary Split Ring Resonator (CSRR) methods to reduce the dimensions of the antenna. The result of this research is a form of a transceiver antenna that works at a frequency of 2.398 GHz to 2.47 GHz with -30.815 dB return loss and VSWR worth 1,074. The resulting radiation pattern is a directional pattern with a gain of 11.84 dB. Implementation of the CSRR method can reduce antenna dimension by 53.47 %.

The P amplitude value for each cycle has not been carried out even though it is related to indications of atrial hypertrophy. The basic interpretation of the maximum P amplitude under normal conditions is 2.5 small squares on electrocardiogram (ECG) paper which is equivalent to 2.5 mV. Apart from these interpretations, an amplitude value is required that corresponds to the amount of depolarization of the atrial muscle cells. The difficulty faced by researchers is the lack of discrete ecg data available for experiments, so it only depends on amplitude data as a function of Physionet output time. An ECG is produced using discrete data but there is no electrocardiograph that displays discrete data yet. This study aims to obtain the P amplitude value based on discrete electrocardiogram data. The cycle duration value obtained from R to R is used to obtain the initial position of the cycle (sc) with the formula RN+1-1.5dR for each cycle. The P amplitude value can be obtained by filtering the maximum amplitude value between the sc and RN positions. The results of research on 10 physionet samples and 10 RSSA samples showed that all samples had an amplitude R, cycle duration and P amplitude value in each cycle.

Measurement process of concrete mold erectness (bekesting) and the floor slope was generally conducted using conventional method applying a plummet (pendulum) for bekesting erectness and waterpass for the floor slope. The drawbacks of this method are it requires a relatively longer processing time and the outcome of the slope measurement is not represented in degrees. The measurement of digital plummet and digital waterpass is easier as the measurement time is relatively short and the tilt angle is represented in degrees. This paper describes a design and implementation of digital plummet and waterpass using Accelero Sensor MMA 7361L based on microcontroller ATmega8. The Accelero sensor MMA 7361L was used to read the tilt axis x, y, and z with analog voltage output that is converted into digital form using the ADC on the microcontroller. Based on the results of tools test for bekesting erectness and floor slope measurement, it was obtained that the average error were 0.51% and 0.49% for x-axis and y-axis respectively.

Movement systems of a mobile robot in an industry generally use the concept of differential drive or ackerman steering. However, both methods tend to have low mobility. This paper proposes an industrial mobile robot design with a holonomic concept using mecanum wheels to maneuver in all directions with better mobility. As a commonly used robot in the industrial field, an arm manipulator is combined with a mobile robot. The mobile robot and arm manipulator's mechanical design is made using software inventor and utilizing acrylic as its base material. The electronic design of the robot is created using Eagle software. After the robot manufacturing is complete, then a user interface is made using the processing IDE. Several robot tests are conducted to ensure that the designed robot runs appropriately. From the functional test results, parts of the robot can run well. The smallest error obtained is 5 cm for the robot heading test, and the most significant error is 20 cm. The testing of a servo motor, which is the arm manipulator's primary actuator, showed the highest error of only 2 degrees. Besides, the gripper of the arm manipulator can also hold objects properly.

A remote control operator enables a robot to perform in a hazard or area which can not be reached by humans. To control the robot, several researchers have equipped a robot with a system which can give others types of feedback information, besides of visual feedback from the robot. One of the feedback types is haptic feedback. The aim of this feedback is to make the operator become immersed with the robot. The existing researchers are using electro-mechanics system. However, these systems are complex, bulky, and hence prevent a seamless embodiment between an operator’s body. The objective of this research is to develop a haptic feedback system combined with stereo vision feedback which compact, versatile and easy to fit. This system is tested to accomplish the task using mobile robot and robot arm. The result shows that this system can help the operator to control robot better.

A measurement system is a process that consists of standards, employees, and methods for measuring particular quality characteristics. Measurement System Analysis (MSA) attempts to evaluate a measuring system's precision, accuracy, and consistency so that clients receive high-quality goods. The previous study implements the MSA for machinery and industrial lines, electronics manufacturing, agricultural and poultry, aviation, and even employee monitoring and inspection. Elsewhere, waste management has problems, especially with capacity measurement instruments and weight sensors. This study aims to: (i) build an IoT-based waste management system; and (ii) evaluate the developed system by implementing the MSA technique, focusing on measurement equipment. The Gauge Repeatability and Reproducibility (GRR) Study Type 1, the (GRR) Study, and the Analysis of Variance (ANOVA) are conducted to evaluate the measurement instrument of the waste management system. The study findings that the total variance of the GRR is 20.95 %, and the distinct categories are 6. Thus, as the Automotive Industry Action Group (AIAG) GRR recommendation, the measuring system is marginal (acceptable in certain conditions). Moreover, the ANOVA result indicates that interaction and operators did not affect measurement outcomes because the blue dots remain inside the acceptable range.

The development of power electronics converters has been widespread in the industrial, commercial, and home applications. The device is considered to produce harmonics in non-linear loads. Harmonics cause a decrease in power quality in the electric power system. To prevent a decrease in power quality caused by harmonics in the power system, the detection of harmonics has an important role. Therefore, this paper proposed feed forward neural network (FFNN) for harmonic detection. The design of harmonic detection device is designed with a feed forward neural network method that it has two stages of information processing, namely the training stage and the testing stage. FFNN has input harmonics and THDi as output. To detect harmonics, frst training is conducted to recognize waveform patterns and calculate the fast fourier transform (FFT) process offline. Prototype using the AMC1100DUB current sensor, microcontroller and display. To validate the proposed algorithm, compared by standard measurement tool and FFT. The results show the proposed algorithm has good performance with the average percentage error compared by standard measurement tool and FFT of 5.33 %.
