Abstract

Abstract: Promotion is an activity carried out to convey, disseminate, and offer products, so that potential consumers are interested in buying. In the implementation of the promotion, CV. Pentaland Jaya abadi uses website media and brochures that still contain 2-dimensional images and information about housing so that potential consumers are less interested because consumers cannot see the exterior and interior shapes directly. Potential consumers usually get brochures through project locations that are still under construction, after that contact the marketing department. One way to solve this problem can be to use augmented reality technology with the appropriate development method is the Multimedia Development Life Cycle (MDLC) which includes Concept, Design, Material Collecting, Assembly, Testing, and Distribution so that this research can produce an android-based augmented reality application that can display 3 dimensional virtual shapes from 3 housing estates including calista haus, grand ayahanda residence and calista homey. From each housing produces 3 dimensional objects on the exterior and interior so that it can provide interest in buying house objects and in addition to that it also helps in the marketing department in promoting housing objects without the need to show many miniatures that require time and also large places. Keywords: Wind Power Plant, Internet of Things, Blynk, ESP32, Charging Module.

Abstract

Distribution transformer is a component in distributing electricity from distribution substations to consumers. Damage to distribution transformers causes continuity of customer service to be disrupted (power cut or blackout occurs). The length of the PLN electricity network requires a transformer to distribute electricity to serve consumers and how to maintain the transformer. The daily load curve of a peak load for housing, shops and factories / industries varies. Load served 200 kVA distribution transformer cannot serve the load on housing, shops and factories / industry. The method used is the replacement of a distribution transformer with a capacity of one stage greater or the replacement of a distribution transformer with a capacity of two levels larger. The distribution transformer carried out by the research is a capacity of 200 kVA replaced by 250 kVA. The ability of a distribution transformer cannot accommodate a load which will increase as an area is advanced. Observations made by calculating the age of the transformer by assuming the annual load growth (r) = 3% = 0.3. Annual peak load (P) = 1.8 p, u increase in oil temperature at peak load (θo = 96.21 0C; 84.16 0C). The increase in the hottest temperature above the oil cover, the increase in the temperature of the hottest place above the oil (θg = 20 0C; 20 0C). The ratio of the load loss to the nominal load excitation loss (Q = 3; 30). By assuming the values of these methods it can be estimated that the life of a distribution transformer is 20 kV, a capacity of 200 kVA is 18 years.

Abstract

Abstract: The continuous use of an electric motor in some industries causes the electric motor to malfunction early. Such damage is generally caused by overheating. Therefore, to overcome the problem of overheating, most industries use two motors that work alternately. Both electric motors function as running and standby which are generally controlled manually by the operator or using a time delay relay (TDR). However, the control of both motors by the operator is not effective because it allows human error to occur. The use of TDR is also ineffective because it does not make the temperature of the electric motor a reference in controlling the work of the two electric motors. This research aims to produce a prototype that can monitor the temperature of the electric motor in real-time and control the electric motor based on the temperature of the electric motor. The Wemos D1R2 is used as a processor to control both electric motors and transmit the temperature of the electric motor to a smartphone via the internet. The MLX90614 sensor is used as an infrared-based temperature sensor. Based on the results of testing the overall performance of the prototype, it is known that the temperature readings of the electric motor are quite accurate with mean error and standard deviation of 0.13oC and 0.15oC, respectively. The prototype is also capable of controlling both electric motors automatically and controlling a cooler via a smartphone.            Keywords: Electric Motor; MLX90614; Overheating; Wemos D1R2.  Abstrak: Penggunaan sebuah motor listrik secara terus menerus pada sebagian industri menyebabkan motor listrik tersebut mengalami kerusakan lebih awal. Kerusakan tersebut umumnya disebabkan oleh panas berlebih. Oleh karena itu, untuk mengatasi masalah panas berlebih tersebut maka sebagian besar industri menggunakan dua buah motor yang bekerja secara bergantian. Kedua motor listrik tersebut difungsikan sebagai running dan standby yang mana umumnya dikendalikan secara manual oleh operator atau menggunakan time delay relay (TDR). Namun, pengendalian kedua motor oleh operator tidaklah efektif karena memungkinkan terjadinya human error. Penggunaan TDR juga tidak efektif karena tidak menjadikan suhu motor listrik sebagai acuan dalam mengendalikan kerja kedua motor listrik tersebut. Penelitian ini bertujuan menghasilkan sebuah prototipe yang mampu mengawasi suhu motor listrik secara real-time dan mengendalikan motor listrik berdasarkan suhu motor listrik. Wemos D1R2 digunakan sebagai prosesor untuk mengendalikan kedua motor listrik dan mengirimkan suhu motor listrik ke smartphone melalui internet. Sensor MLX90614 digunakan sebagai sensor suhu berbasis infra merah. Berdasarkan hasil pengujian kinerja prototipe secara keseluruhan diketahui bahwa hasil pembacaan suhu motor listrik cukup akurat dengan mean error dan standar deviasi masing-masing 0,13oC dan 0,15oC. Prototipe juga mampu mengontrol kedua motor listrik secara otomatis dan mengontrol sebuah pendingin melalui smartphone. Kata kunci: Motor Listrik; MLX90614; Panas Berlebih; Wemos D1R2.
