Abstract

Design of electrical system in the Faculty of Economics and Management Bogor Agricultural Institute was based guidance consisting of PUIL, SNI, as well as provisions of modern security and technology and aesthetic beauty. Design is also based on the relevant IEC standards, specifically IEC 60364. In the electrical system, it is necessary to pay attention to the conductor and safety factor to minimize power losses and drop voltage. Losses on the customer side due to drop voltage besides damaging electrical equipment is customers only can have a voltage less than 220 V. The distance between load panel and main panel is directly proportional to the drop voltage value, much farther the load panel to the main panel, resulting greater drop voltage value produced. The calculation of drop voltage based on total load, length, and area of conductor. To overcome the problems that occurred in this case study, the conductor uses 1.25 times the nominal current as a safety factor. The selection area of conductor can be said to be quite good with the farthest drop voltage value from SDP-TR is 0.89%. The total amount of electricity in the building is 158.33 kVA, assuming that if there is an additional 5-10 years, the total electric power and 15% of the others SDP is 182.04 kVA.

Demand for electricity is increasing rapidly, the consequence of this is a threat to the stability of the electrical system, one of which is the voltage stability. FACTS or Flexible Alternating Current Transmission System is electronic equipment that is able to regulate electric power transmission that can be used to overcome stability problems. This research will analyze the use of Static Var Compensator (SVC) as one of the equipment from FACTS to overcome the stability of the most critical buses by using the 500 kV Java-Bali electricity system using PSAT. Results from using the power flow method in the 500 kV Java-Bali case show that the total active power generation is 12.144 p.u. and the total reactive power generation is 5.268 p.u. This value is obtained from the total addition of active power generation and reactive power of all plants in the 500 kV Java-Bali system. While the total active power load is worth 12.058 p.u. and the total reactive power load is 4.65 p.u. This value is obtained from the total load on each bus plus the total losses incurred on the line.

Abstract

The growing population is causing a big problem in terms of waste.  Garbage sorting efforts need to be made, especially the separation between organic and non-organic garbage, so that non-organic garbage that can still be recycled is not contaminated by organic garbage containing water and oil. Moreover, it requires swift handling of trash bins that are full so that trash does not accumulate and become an epidemic. For that we need innovation in the form of technology that is able to overcome these problems. This paper is designed IoT-based garbage for monitoring and separating dustbin. The design of garbage was made using Arduino UNO as a microcontroller that can monitor and sort garbage automatically. There are 2 stages in the garbage sorting process. The first stage is the metal and non-metal separation, and then the second stage is the organic and non-organic stages. When the trash is full, the trash can lid will be locked and then the system will send a notification to the garbage manager regarding the location/position of the trash and the weight of the trash. This research method includes 4 stages such as analysis of needs and working methods, design of hardware and software design, implementation, and finally testing of the design.Keywords— garbage, waste management, garbage sorting, separting dustbin, internet of things

Abstract

Electric vehicles is in rapid development. The energy commonly used as a driving force for electric vehicles comes from batteries. The development of electric vehicle technology is currently concentrated on efforts to charge the battery used by utilizing the power wasted when braking electrically. The gearbox and final drive are installed as a mechanical transmission system for electric vehicles to increase the torque of the BLDC motor as the main driving force of the vehicle. The regenerative process occurs when the Kelly-KBL motor controller electric braking feature is activated. For this reason, Arduino Mega and LabVIEW software are used to observe the current and voltage of lead acid batteries with voltage 48 V and capacity 225 Ah (C20). In addition, a 2 kW BLDC motor RPM was also observed in the electric braking monitoring system. From the results of monitoring and data collection, the vehicle traveled a distance of 36.06 m in 68 s time intervals with an average speed of 16.8 m / s. The average torque value when electric braking on a BLDC motor supplies 154 Nm, while the average torque of the vehicle is 996.99 Nm. The average regenerative power of the wheels is 17.07 kW, while the average mechanical power of the wheels is 13.67 kW. Coulometric state of charge (SOC) shows an increase in battery capacity of 4.27% and 99.97% voltage SOC at the beginning of the activation of the electric brake pedal. Maximum battery power movement when charging, 2.25 kW is caused by the activation of the electric brake pedal. Whereas when using a maximum of 1.52 kW. The application of electric braking has a power consumption efficiency of 0.042%. and charging power charging 18.97%.
