JEEMECS is an Open-Access journal who managed by Electrical Engineering Department, Faculty of Engineering, Universitas Merdeka Malang, Indonesia. The technologies are rapidly changing and updating. Thus rapid distribution and publication to researchers, engineers, and educators are very important. Our aim after receiving the manuscript and editing process required is to quickly publish the received letters. Publishing periodically 2 (two) times a year. More several other changes in JEEMECS are informed in the journal history.

Abstract

The presence of 3 comparable phases in the Ulumbu geothermal power plant affects the existing system, so it is necessary to conduct stability analysis to be able to find out the Critical Clearing Time (CCT) of the Circuit Breaker system that can maintain its synchronous condition. The results of the transient system analysis to determine the Critical Clearing Time were carried out when the 3 phases of the Ulumbu geothermal power plant were 0.4 seconds and showed that the level of voltage, frequency, and rotor angle would be faster DOI :  https://doi.org/10.26905/jeemecs.v1i2.2353

Abstract

Organic waste is the residual daily activities of humans or natural processes in the form of solid or semi-solid in the form of organic or inorganic substances that are biodegradable or unraveled which are considered useless and disposed of in the environment. This organic waste can be used as fertilizer for plants if processed properly, therefore this waste can be used as fertilizer processing by destroying, so this study aims to create a tool that can destroy waste so that it is easy to process using an Arduino microcontroller, the design is done ranging from hardware to software. The way the device works is to detect the material to be destroyed, then the system will be active, the tool is designed a choice of time for the material to be destroyed so that the appliance will automatically die when the time expires and the choice of blade rotation speed from maximum, medium to minimum. From the experiments carried out the tool was able to destroy the material until smooth.DOI : https://doi.org/10.26905/jeemecs.v1i2.2377

Abstract

Problem with Coupled Tanks is the appearance of interference in the flow that supplies the tank will make the response unstable, resulting in cross-interaction between each input and output. Fuzzy Logic Control (FLC) has its own advantages that is effective in dealing with complex non-linear systems. Adaptive Fuzzy control Auto tuning has the ability to maintain the steady state response value from interference. Adaptive Fuzzy methodology is attractive choice when formulation in the method proposed for the Coupled tank process. Adaptive Fuzzy control has the ability to maintain the steady state response value from interference. In this study using decoupling in the cross interaction process in each tank. Coupled Tanks on the TITO system can change the transfer function to SISO, so as to minimize the effect of interacting. The right way to design modeling is to pay attention to the state of the plant, so that the desired control model can overcome the non linearity of the TITO system. Adaptive Fuzzy method expected to have percent overshoot and better settling time value.DOI : https://doi.org/10.26905/jeemecs.v1i2.2423

Abstract

Telecommunications systems especially WCDMA networks, require an antenna to convert electromagnetic energy in the air into electrical energy will be processed into the information signal. WCDMA (Wideband Code-Division Multiple Access) network works at a frequency of 1900 MHz with a complicated configuration antenna and has high-cost components. Directional 1900 MHz Square Patch Ring Slot Microstrip Antenna for WCDMA has been proposed. This is a novel technique in telecommunication configuration to make directional antenna use more proper and efficient component by using low cost and easy to find material at 1900 MHz frequency. This compact configuration consists of a single rectangular patch, a substrate, a ground plan and ring slot on the ground plane. This antenna produces an accurate frequency at 1900MHz with the value of -15.19 dB and gains 6.78 dBi at. The overall size of the proposed antenna is 55.7 mm times 49.2 mm with FR4 (Phenolic White Paper) with a dielectric constant value is 4.4. DOI : https://doi.org/10.26905/jeemecs.v1i2.2626 Telecommunications systems especially WCDMA networks, require an antenna to convert electromagnetic energy in the air into electrical energy will be processed into the information signal.

Abstract

The sea has many potentials to be utilized based on the ecological aspects of coastal area. Almost in the coastal areas and islands in Madura are experiencing difficulties in utilizing marine resources. Salinity changes influenced by water osmotic pressure whereas biota living in salt water should be able to adjust the osmotic pressure from its environment. The changes in pH have an effect on the survival of marine organisms as not all saltwater creatures survive with the change of it. From these problems a system of "Designing Measure of Salt Measure and Sea Water pH Using Fuzzy Logic Based Android" is made. Where measuring system is made to prioritize the level of accuracy of changes in salinity and pH value of sea water. So that people could exploit the sea potential based on the condition of the sea water. The reading of sea water condition changes using salinity sensors, pH sensors, and MCU nodes as communication with android devices. Input from the sensor can be sent to the web server and received by android and then processed by fuzzy logic method to get the maximum output. The system can work according to what is expected during 5 days of testing in different locations. The success of this system is 97.3% with a 2.07% failure rate.DOI : https://doi.org/10.26905/jeemecs.v1i2.2662
