Abstract In this study, a Bluetooth-based Android application interface is developed to perform a manual and automatic control of a four-wheel-driven mobile robot designed for education, research, health, military, and many other fields. The proposed application with MIT App Inventor consists of three components: the main screen, the manual control screen, and the automatic control screen. The main screen is where the actions of the control preference selection such as manual control and automatic control and the Bluetooth connection between the mobile robot and Android phone occur. When the robot is operated manually for calibration or manual positioning purposes, the manual control screen is employed to adjust the desired robot movement and speed by hand. In the case of the need for automatic motion control, the desired robot position and speed data are inserted into the mobile robot processor through the automatic control screen. At the first stage of the work, the proposed Android application is developed with the design and block editors of the MIT App Inventor. The compiled application is then installed on the Android phone. Next, the communication between the Arduino microcontroller used for the robot control with the Bluetooth protocol and the Android application is established. The accuracy of the data dispatched to the Arduino is tested on the serial connection screen. It is validated that the data from the Android application is transferred to Arduino smoothly. At the end of this study, the manual and automatic controls of the proposed mobile robot are performed experimentally and success of the coordination between the Android application and the mobile robot are demonstrated.

In this paper, the muscle relaxant agent (i.e., cisatracurium) and three clinical control methods (i.e., 13 patients undergoing intermitted bolus control, 15 patients undergoing intensive manual control and 15 patients) undergoing automatic fuzzy logic control (FLC), were used for maintaining depth of muscle relaxation (DOM) during surgery. Cisatracurium, a muscle relaxation drug with long-term effect, low metabolic loading, but long delay time, is widely used in operating rooms and ICUs. Meanwhile, the rules for the FLC were developed from the experimental experience of intensive manual control after learning from 15 patient trials. According to experts' experimental experience, our FLC inputs were chosen from T1% error and trend of T1% which differ from other previous studies on eliminating the effect of time delay from cisatracurium. In individual clinical experimental results, the mean(SD) of the mean T1% error in 13 patients for intermitted bolus control, in 15 patients for intensive manual control, and in 15 patients for automatic control was 8.76(1.46), 1.65(1.67), and 0.48(1.43), respectively. The t test results show that automatic control is not significantly different from intensive manual control. The results show that a simple fuzzy logic controller derived from anesthetists ' clinical trials can provide good accuracy without being affected by the pharmacological time delay problem.

Snakehead (Channa sp.) was one of the superior freshwater fish species native to Indonesia that has been successfully domesticated. The increasing demand for snakehead fish on the market has resulted in the addition of cultivated land and water use. Aquaponics technology was a combination of fish farming and plants that grow without soil media. The aim of this research was to determine the best composition of probiotics that can be used in aquaponic technology to optimize growth rate and feed conversion of snakehead fish (Channa sp.). This research used an experimental method. The experimental design used was a completely randomized design with four probiotic combination treatments and each treatment was repeated three times. The results showed that awarding of different probiotic compositions in the aquaponic system resulted in a spesific growth rate that was not significantly (P>0.05) different between treatments. The highest value of spesific growth rate were in the treatment of probiotic composition of Lactobacillus casei and Saccharomyces cerevisiae with a value of 4.11%/ day. Awarding of different probiotic compositions in the aquaponic system results in significantly (P<0.05) different feed conversion ratio values. The best feed conversion ratio values were in the treatment of probiotic composition of Lactobacillus casei and Saccharomyces cerevisiae with a value of 1.78. The conclusion of this study was the composition of probiotic Lactobacillus casei and Saccharomyces cerevisiae was the best probiotic composition to increase the spesific growth rate and feed conversion ratio of snakehead fish.

Abstract This study intends to explore fuzzy logic control on clean water turbidity process with dissolved air flotation (DAF). Three different strategies were tested to regulate clean water turbidity by manipulating the saturator vessel flow output aiming for low actuators control effort. Saturator pressure was the manipulated variable (MV) in the first control loop named SISO I. The second control loop, SISO II, used recycle stream valve opening as MV. The third control loop (MISO) was developed applying fuzzy logic instead PID control. Several performance criteria were used to analyze the process control performance such as integral absolute error (IAE), recycle stream valve and saturator vessel pressure regulating valve control efforts, ECV01 and ECV02 respectively. Results from SISO I and SISO II strategies showed that recycle stream is a better MV than saturator vessel pressure for clean water turbidity control in the DAF process. Only SISO II and MISO strategies proved to be capable of regulating the process variable. However, MISO control showed better performance based on IAE value against SISO II, with a reduction of 11.24% on its value, even the recycle stream valve control effort for MISO control being fairly higher than that for SISO II. Nevertheless, fuzzy logic control application gave rise to better turbidity control, and consequently prevented the excessive use of clean water in the recycling stream.

Technological progress in augmented reality (AR) creates new application opportunities for different branches of tourism. The application of modern technology is made possible by the widespread use of mobile devices and dedicated tourist applications. Preliminary market research demonstrates that there are no global solutions intended for tourists on sea voyages that make use of augmented reality. This paper analyzes the use of AR technology in water tourism. The proposed Maritime Educational Trip (MET) system makes it possible to combine geolocation information with the accumulated knowledge of a specific location and to present it with AR. An example prototypical Android application is developed, combining e-navigation with a knowledge base. The developed solutions show how a combination of the real world with a computer-generated world helps to expand the tourism space.

Arowana fish farming sector is one sector that can support the economy of Indonesia society. But most fish farmers in Indonesia are still using conventional procedures for the cultivation of fish that can cause a variety of losses. In this study offered a solution in the form of a simulation design of an Arowana Fish Nurseries Monitoring System-Based on The Iot Scheme using Cisco Packet Tracer 7.0 Application as a Simulator. In the designing process, the monitoring system will be split into two sub system such as security system and arowana aquaculture support system. There are four kind of sensor that can be used in the simulation process such as CO2 Detector, Temperature Monitor, Motion Detector, and Water Level Monitor. If the sensor detects a value that does not match the specified parameter then the attenuator of the sensor will react according to the conditions set through the condition setting. Information generated by these devices will then be sent to the server, then to access information and monitor the devices can be done through a web server that has been available. The result from this study is that the simulation can run well but there are still shortcomings because of the limitations of the simulator used so it is expected that in the next version of simulator the limitations can be overcome
