Abstract

Abstract This research is indicate that the ability of early warning system technology in giving information early related to floods quickly and nowadays especially in watching condition of rainfall and ebb intensively. Therefore require to be designed by appliance which can give the early information to society in region of gristle of floods disaster to conduct actions which require to be drawn up by before the happening of disaster. Location of floods gristle selected by countryside of sand the mempawah subdistrict go downstream the forewarning system designed use the programmable logic controller (PLC) and system can give result of information in the form of forewarning indicator which is depend on storey, water height level, that is normal level, attentive level, alert level and caution level. Water height level can be watched from face door irrigate as one of appliance to support the system of forewarning floods disaster. Design result to develop, build this appliance is very be of benefit to society in doing early anticipation possible the happening of floods disaster, so that loss generated by effect of floods disaster felt by society during the time earn the minimum. The existence of forewarning appliance is threatened society of danger can act during which is last for lessening possibility of the happening of hurt victim, loss of soul, and destroy the good and chattel. Keywords Early, warning, system, floods, disaster.

Abstract

Abstract This paper presents the use of Coloured Petri Net (CPN) for modeling and analysis on Automation system. Flexibility and re-configurability are prominent requirements for the current and future automation system. For complex systems, a dominant characteristic is modularity of functional modules. Therefore, a modular approach in building a CPN model is proposed in this paper including its analysis. This aaproach is useful to avoid the construction of a single state space of the entire system and get a simplified model. As an illustration, modeling and state space analysis of the given example by means of CPN is given. Keywords Coloured Petri Net, Modularity, Automation, Scheduling, Verification.

Abstract

Abstract The Objective of this research was to analyze effect of additionheat to electrical comsumption onAir Conditioner(AC). This research using a unit of split AC with capacity 9000 Btu/h and R22 refrigerant, set up on 4 x 4 meter room size. Condition of room experiment was varied by getting additionof heat from workers, electrical equipment and give some ventilation effect by opening the door every and 1 hour. The result of research showedthat by additionof cooling load in the room causing time required for conditioning thetestroomat 25 of temperature is longer, thus theelectrical energy consumed wasgreater. In theempty room, the timefor conditioning the test room at temperature up to 25oC is 1 hours, with electrical energyconsumptionis 1.26kWh. The roomwith3 people workers, 1computer and1Laptop, the time required is2hours with electrical energy consumptionis 1.68kWh. The roomwith3 people workers, 1 computer, 1 laptop and the door was opened with 50% wide everyhour, the time required is3hours with electrical energyconsumptionis 2.54kWh. The roomwith3 people workers, 1 computer, 1 laptopandthe door was opened with 50% wide every1hour, the time required is2hours with electrical energyconsumption is2.10kWh.

Abstract

The process of converting solar cell electrical energy is a form of utilizing environmentally friendly alternative energy sources (renewable energy). The conversion system is in the form of PV panels that are installed in a location exposed to sunlight and unobstructed. Monitoring is carried out when the sun shines from morning to evening. The location of the panel is in the vehicle parking lot of the engineering faculty, while monitoring is carried out in the Control Laboratory of the Tanjungpura University Engineering Faculty, which is 300 meters away. Factors that determine the quality of PV panels are the system and dimensions. This shows that fluctuations in current (I), voltage (V) and power (P) need to be controlled so that load distribution and reserves can prevent reduced energy generation. Observation and control using Long Range Area (LoRa) radio transmission media connections, Internet of Things (IoT) and Programmable Logical Control (PLC) in real-time. Observation and test results show that energy generation has experienced an increase in temperature which has an impact on reducing power. Meanwhile, the effect of the distance between the installed panels produces an average delay of 7 milliseconds (midday conditions). Meanwhile, the Signal to Noise Ratio (SNR) value for data transmission is 30 dBm at the device frequency of 868.125 MHz. Baud rate 2400-9600 bps with a speed of 0.3 bps "“ 62.5 Kbps. The application of this system is a research novelty because it can determine and control the generation of electrical energy at minimum, maximum and optimum conditions with a certain distance between the observer and the installed panel.
