Changing the dc sgnal to ac signal is done for te purpose of load regulations, such as the ac motor speed, heater and lamp. Inverter work is done by ac rectification first and then converted again to a 1 phase ac signal. The ac output signal is a sinosoidal PWM (SPWM) type of unipolar 220 volts from the input 24 volt dc voltage. Unipolar SPWM signal generation is done by a microcontroller with programming. The number of counts (resolutions) of the SPWM signal and the period are set from the amount in the register, can be set to 8 bits or other constants. The power part of the SPWM inverter is the N channel MOSFET bridge circuit H with IR2110 solid state driver. Step transformer as a load while step-up the inverter output voltage. Determination of the output frequency is set through a rotary encoder that can be adjusted up (increment) or down (decrement). There are 5 frequency variations, namely 30, 40, 50, 60 and 70 Hz. To get the inverter efficiency, the type of MOSFET used is chosen to have the type that has a low RDS (on) value and the right driving pulse, according to the switch configuration. Measurement of the output frequency is done by reading the image on the osciloscope. The observations show a frequency value that is almost the same as the constant. The test results show the difference in output voltage which is reduced at a 30 watt load.

The good performance of a clock generator circuit in the power supply for triger TTL IC is very influential on the success of the lab. A series. Therefore, the effectiveness of use must be adapted to its use in the practicum. To create a clock generator circuit as a source of pulses from a digital counter IC, a timer IC can be used. This pulse generator or clock generator can be used for clock sources in making counters up and down. Clock generators are often referred to as clock generators. The pulse generator in making the circuit is often used linear integrated circuit (IC: Integrated Circuit). A linear IC that is commonly used in general is usually the NE555 which is a timer IC. As a timer it can also be used analogically as a Clock Generator or pulse generator which can generally generate the frequency or time as needed.

The unbalanced load on distribution transformers is mostly caused of connecting new customers and changing patterns of electricity usage in the community. The impact of the unbalanced load is the emergence of a current flowing on the transformer neutral conductor that causes energy losses. Load balancing of distribution transformers is commonly done by technicians, but the implementation takes quite a long time and is repeated, sometimes up to 4-5 times to get the appropriate results. This is more due to less valid customer phase data. Customer phase verification is needed to accelerate the load balancing process in an effort to reduce losses in distribution transformers. With valid customer phase data, just one stage of load balancing can reduce losses by 1.06%.

Abstract - Picnometer is a tool made of glass that has a shape that resembles a perfume bottle. Picnometer is a tool used to measure density or fluid density. There are various sizes of picnometer, but what is often used in the laboratory is the size of 50 ml. Constraints that often occur when measuring density are measurements that cannot run optimally and result in specific gravity taking takes longer. The reason is when moving the asphalt liquid to an asphalt liquid picnometer about the neck of the picnometer, so that repetitive displacement is carried out. When measuring material density, the asphalt temperature ranges from 150 ° C - 170 ° C. Here a PLP (Education Laboratory Staff) of Malang State Polytechnic makes an improvement on the asphalt liquid density. Modifying asphalt density measuring aids, namely funnel extension (funnel) and funnel stand. With the modification, it is hoped that the density measuring instrument can function optimally and become an international standard laboratory
