Abstract

Indonesia is a tropical country that has two seasons, namely the rainy season and the dry season. During the dry season, the weather gets hot so AC technology (Air Conditioner) technology is really needed by the people of Indonesia. Every day, air conditioners are often used to cool the air, so the use of air conditioners is very routine in the dry season. Ac needs to be maintained regularly so that the AC is not easily damaged. Ac is divided into two parts, namely indoor and outdoor. Indoor and outdoor are connected through copper pipes which are freon gas lines. Freon gas will be pumped through the outdoor using a compressor engine to suppress the flow of freon gas so it flows into the evaporator section of the indoor and the compressor will suck the freon gas again to the condenser section on the outdoor because the compressor is the most important part in the air conditioner, the compressor must be routinely maintained by knowing the amperage performance on the compressor. So the purpose of this research is to monitor the performance of the compressor. This monitoring is done by installing a LANCAR (broken air conditioner notification service). LANCAR has three parts, namely electronics as a tool to detect compressor performance amperes, applications as notification media as well as for monitoring compressor amperes and database as compressor amperage data storage. Electronics used such as NodeMCU esp 8266, current sensor, vibration sensor and 1 channel relay module. These parts will be connected to the IoT (internet of things) system where the device is able to provide notifications when the compressor is damaged and the amperage data on the compressor will be stored in a database so that it can later be seen by the AC owner.

Abstract

Aquaponics is one of the methods of farming in urban areas that produces fish and vegetables at the same time. One aspect that can improve the quality of aquaponics products such as catfish and water spinach in a short period of time is the addition of Internet of Things (IoT) systems. This technology allows farmers to automate work and monitor aquaponics media remotely. Before applying this technology, it is necessary to analyze to what extent each aquaponics system improves the quality of fish and vegetables. The purpose of this study is to compare the productivity of materials needed to grow catfish and water spinach in IoT-based aquaponics and conventional aquaponics. The parameters studied to support the results of the analysis are fish weight and vegetable weight after 14 days. The results show that the weight of fish and vegetables produced by IoT aquaponics is heavier than that produced by conventional aquaponics, which leads to a higher number of production units. It makes the IoT aquaponics productivity percentage value greater with a productivity difference of 112%, which indicates that the IoT aquaponics system manages the required materials more efficiently in a short period of time.

Abstract

The aquarium monitoring system in the maintenance of ornamental fish is fundamental to maintaining the survival of the aquatic biota in it. In this study, a prototype of a water condition monitoring system such as turbidity and water temperature in freshwater ornamental fish aquariums was designed and integrated with IoT technology so that it could make it easier for ornamental fish owners to maintain freshwater ornamental fish remotely. In the prototype tool, there is a turbidity sensor SEN0189, a temperature sensor DS18B20, and an HC-SR04 sensor, which function to measure changes that occur in each parameter. Each sensor data will be processed by the Arduino Uno microcontroller, which is then sent to the NodeMCU ESP8266 (Wi-Fi module) via serial communication so that sensor data readings can be displayed on the Blynk application. As a result of the tests, the system can monitor the turbidity of the water and drain the water if the turbidity reaches >= 25 NTU and refill the aquarium with clean water. In addition, the system can also monitor and control the water temperature in the aquarium. The aquarium water temperature level is maintained in the range of 24°C – 28°C.

Abstract

Nowadays, many Indonesian people working as a fish cultivator. This is because the turnover obtained from the sale of fish, one of which is koi fish is quiet high. To cutivate fish especially koi fish, ultivators will make many pools to cultivate these fish. From the first is spawning pool, tiller fish pool and brood pool. To get good quality cultivation, the pools must always be clean (has a turbidity level of water < 400 NTU). Therefore, a system was created to be able to monitor the water turbidity level and automatic feed in koi fish pool which the purpose is helping koi fish cultivator improve their cultivation quality. The monitoring system of the cultivation pool turbidity level works by reading the turbidity value of the pool using a turbidity sensor (Turbidity Sensor). The reading of the sensor value will be processed by the NodeMCU microcontroller and then activate the drainage pump relay module for which will drain turbid water. On the other hand there is a proximity sensor that will measure the height of the pool water. When the pool water is drained, the proximity sensor will send a signal to the NodeMCU microcontroller to activate the distribution pump relay module, so that it can distribute clean water from the water tank to the pool. Therefore, the cultivation pool’s water always be clean. Meanwhile, automatic feeders work using the RTC (Real Time Clock) module in which the feeding time will be set in this module. Then, the time output from the RTC module will be processed by the NodeMCU microcontroller which then sends a signal to the servo as the drive for the fish feed lever. When it is time for feeding, according to the program provided the fish feed lever will open. Therefore, feeding can be done automatically. Keywords — IoT, monitoring, turbidity, feeder, koi fish, cultivation pools.

Abstract

Abstract— In maintaining the quality of aviation fuel, before being marketed, the aviation fuel must pass through the filtering stage using a filter. The use of filters must be monitored for efficiency by using a PDG (pressure different gauge) instrument. PDG is a measuring device that is equipped with a switch and will be a disconnect when the PDG needle shows a number above 15 psi. However, filter monitoring is only done by looking at the PDG installed on each filter and the switches on the PDG have not been used at all. From this problem, the author conducted research out by designing and building a tool that can monitor switches on the PDG and provide SMS notifications. In its design, the device uses Arduino Uno as a microcontroller with a 12VDC power supply. This device is equipped with GSM SIM900A which functions to send SMS. Based on research, the highest current consumption is 0.18 A and the smallest is 0.11 A. The average time for sending an SMS is 7 seconds. Based on testing the tool can work as expected. With the design and construction of this device, it is expected to help PT. Pertamina DPPU Ngurah Rai to monitoring the performance of filters in realtime so that the replacement of filter elements can be done in a timely manner and maintain the marketed aviation has good quality.
