Abstract

A case study in a steam power plant has been conducted and reported. There was a case of decrease in the freshwater production rate in multi effect distillation installations that may disrupt the operation of the power plant. The cause was suspected by the drop in vacuum pressure in the evaporation chamber. The study was conducted by studying the MED installation process diagram and performing the theoretical calculations of energy and mass equilibrium in each chamber. To make it easier to find the properties of water in the energy calculation then add ins water_97 in Microsoft Excel is added.Calculations were undertaken in two modes, commissioning period and 2016 operation mode. The difference of the two modes was vacuum pressure level in each chamber. Vacuum pressure level in 2016 operation mode was lower than commissioning mode. The calculation at commissioning mode resulted in a production rate of 133.56 ton/h, while the actual condition at that time was 127 ton/h. Calculations in 2016 operation mode produced a theoretical fresh water production rate of 101.37 ton/h.

Abstract

Current refigeration technology has an important influence in improving the quality of food products. The purpose of this study is to find out how much the difference in performance generated from the expansion device in the form of two capillary pipes of different diameters and know the power consumption of electricity used, so that it knows the electric power per day. The method used in this study is to test the ice cream maker refrigeration system, by testing its performance by measuring the temperature and pressure in each main component when the system is steady. The results of the actual COP value of the average capillary pipe diameter of 0.028 inches are 2.16 while the actual COP value of the average capillary pipe diameter of 0.031 inches is 2.74. And the actual COP value of a 0.028 inch diameter capillary tube has a greater value of 2.16 while a capillary pipe with a diameter of 0.031 inches has a smaller value of 1.88. Whereas the biggest value of refractive efficiency at the average value is a capillary pipe with a diameter of 0.028 inches of 63.58%. While for capillary pipes with a diameter of 0.031 inches smaller the value of refraction efficiency averaged 59.49% and the cabin temperature in capillary pipes with a diameter of 0.028 inches, the average value was -9.82 0C. While for capillary pipes with a diameter of 0.031 inches smaller it has a cooler average value of -9.09 0C.

Abstract

The Kwh Meter Automatic Meter Reading (Kwh Meter AMR) system is a system for recording electricity meters that is carried out automatically and remotely. Data communication sent by the AMR kWH meter at PT PLN (Persero) UP3 Indramayu uses an AMR modem as an electronic kWH meter interfacing with a wireless telecommunications network. The AMR kWh meter has a feature that besides recording the use of electrical energy used, it also records voltage, electric current, power factor, and the recording time of the customer's electricity usage meter is faster. PT PLN (Persero) UP3 Indramayu can carry out distribution network management which makes it easier in terms of distributing energy to customers and monitoring the use of electrical energy by customers. In operating the kWh meter AMR system can reduce losses caused by abnormal use of electrical energy by customers. These abnormalities include incorrect Wiring, errors in wiring on the Kwh Meter, Unbalance Current, unbalanced electricity usage by customers, Blank Kwh and AMR modem hangs/damages so that the communication signal is unstable and fails to retrieve data on electricity consumption by customers. To overcome these abnormalities, a check is carried out on the customer according to the findings of abnormal deviations in the AMR application. The use of unmeasured electrical energy during the Kwh Blank abnormality is 4,619 kWh with a total follow-up billing fee of Rp. 6,936,537.-. The results of the abnormality category of Incorrect Wiring were carried out by normalizing wiring errors in the Kwh Meter phase S and Phase T. The results of the Unbalance Current abnormality category, the electricity consumption at the customer at that time was not balanced, that is, the T phase was not used by the customer. The results of the AMR Modem abnormality category are replaced by the AMR Modem so that the customer's electricity consumption is again disabled in the AMR application.

Abstract

This research was conducted to find a solution to the problem of waste, especially organic waste which is generated from households and shopping centers, especially traditional markets. Many people do not understand how to deal with waste properly. The most common way that most people do is by burning organic waste. This has a negative impact on the environment and public health itself. Therefore it is necessary to do research on how this organic waste can be utilized for the benefit of society. One way to overcome the problem of organic waste is to make an organic waste chopper. The machine is equipped with a knife designed in such a way that it is capable of cutting to small sizes. In this study, this organic waste chopping machine will be used to produce pieces of waste which will then be used as biogas reactor material. To be continued in the process of making biogas. From the research results obtained the following machine specifications: Machine size with a length of 0.704 m, a width of 0.413 , and a height of 0.601 m. This organic waste shredder uses a motor with a power of 5.5 hp, a belt length of 798.47 mm, a drive pulley rotation of 2784.65 rpm and a blade rotation speed of 7.35 m/s.

Abstract

Water is a source of life for all living things. However, currently the amount of clean water available is very limited so that it is not comparable with the increasing growth of the world's population. The saving effort that can be done is to make the best use of water. One of them is by saving bath water by controlling the water level in the water reservoir. In this final project, an automatic faucet is designed using an ultrasonic sensor, namely a sensor that will detect the presence of an object and remove or turn off water automatically with the main actuator using a servo motor. In filling the water reservoir to prevent water from overflowing, an ultrasonic sensor is used which will automatically fill when the water volume distance is not within the specified range and will also automatically stop filling when it is within the specified range. So that no more water is wasted due to user negligence.
