<![CDATA[Water is a living medium for goldfish, which greatly influences their lives. Water quality as a living medium for fish greatly influences the growth and development of goldfish; therefore, water quality must meet the needs of goldfish. Several water quality parameters that greatly influence fish life are temperature, degree of acidity (pH), and solid substances dissolved in water (TDS). The aim of this research is to design a monitoring system capable of measuring temperature, degree of acidity (pH), and solid substances dissolved in water based on the Internet of Things. This tool is used for an Internet of Things-based water quality monitoring system in goldfish aquariums, where the results obtained will be sent via smartphone to the Blynk application. And it can also provide food automatically and provide notifications if the water becomes cloudy. This tool is designed using an Arduino Uno, a Wemos D1 R2 controller, and sensors used to measure each parameter, namely the DS18B20 sensor, pH sensor, and TDS sensor. Then the feeder uses a servo to open the feed and an RTC as a timer. The results of this research conclude that the calibration results for the DS18B20 sensor have an average accuracy rate of 99% with a sensor error percentage of 1%, the pH sensor has an accuracy rate of 98.7% with an error percentage of 1.3%, and the TDS sensor has an accuracy rate of 94.59% with an error percentage of 5.41%.]]>

<![CDATA[Presence is a procedure or process that needs to be carried out by all employees or members of a company or agency. The attendance register is a reference and benchmark for assessing, measuring, and determining the quality and quantity of each member or employee of the company or agency. Presentations carried out manually are considered less effective and efficient in terms of time and usage. So it is necessary to build an intelligent attendance system, one of which is by creating an intelligent attendance system that uses IoT-based fingerprint recognition technology with an Arduino controller and outputs to an Internet or intranet server. Based on the results obtained in the research, administrators can float their side servers freely. The time for sending data from the presence device to the server uses the POST method, with an average time of 8 seconds on an intranet network with a maximum distance of 25 meters from the wireless router or access point. By creating this attendance system, it makes it easier for the Surya Pematangsiantar Education Foundation to record the attendance of teachers and staff, especially SMK units.]]>

<![CDATA[The Head of Warehouse has the main responsibility to manage and supervise the daily operations of the warehouse, including receiving, storing, and dispensing goods. In addition, the warehouse head is responsible for leading the warehouse staff team, providing the necessary direction, training, and supervision to ensure efficiency and safety in warehouse operations. This study aims to select warehouse heads by applying a combination of MOORA and PIPRECIA methods, as well as GRA and PIPRECIA. The combination of MOORA and PIPRECIA as well as GRA and PIPRECIA will be compared based on the final ranking of the two methods used. Based on the ranking results on the MOORA Method, the highest value with a value of 0.40017 was obtained by FHY with rank 1, a value of 0.36637 was obtained by AGL with rank 2, and a value of 0.35721 was obtained by YLS with rank 3 Based on the rating results on the GRA Method, the highest value with a value of 0.12164 was obtained by AGL with rank 1, a value of 0.12017 was obtained by FHY with rank 2, and a value of 0.1054 obtained by TAN with rank 3. Ranking differences between Multi-Method Objective Optimization by Ratio Analysis (MOORA) and Gray Relational Analysis (GRA) can arise due to differences in approaches in evaluating and comparing alternatives. The results of the conformity test can be concluded in the selection of warehouse heads who recommend the GRA method compared to the MOORA method, because the results of the conformity level of the GRA method get a value of 99.99919% higher than the MOORA method.]]>

<![CDATA[One of the advantages of solar cells is their ability to generate electricity without creating noise or air pollution. However, they have the disadvantage of increasing temperature due to continuous exposure to solar radiation, thereby decreasing solar cell efficiency. A solution to mitigate this effect is a cooling system for solar cells. Cooling methods for solar cells consist of active and passive methods. Active cooling methods for solar cells require power consumption, necessitating analysis and evaluation of their efficiency in practical applications. This research analyzed the power efficiency of a cooling system using a water pump, peltier, and fan. The power measurements generated by the cooled solar cell produced a power efficiency of 8.64%, compared to a solar cell without cooling. Meanwhile, the average power efficiency over six data collections was 7.82%.]]>

<![CDATA[In the electric power system it does not always run normally. There are many disturbances or disturbance anomalies that can disrupt the operation of the system. One of them is at the Sekarputih main substation. last two years, the channel has experienced five short- circuit disruptions. As a result, electromagnetic distance relays must be replaced with digital distance relays equipped with reclosers. The reclosers will function when there is a relay disturbance on a trip and automatically reconnect. The disruptions may occur due to damage brought by unstable weather conditions. Indirectly, the value of relay settings will change and deviate from the PLN (state electricity company) standards. Therefore, relay re-setting was performed using two methods: the Fuzzy Mamdhani and the ANFIS methods. Using the Fuzzy Mamdhani method, the relay distance settings were as follows: Zone 1 = 0.523 Ω, Zone 2 = 0.54 Ω, and Zone 3 = 1.58 Ω. Meanwhile, the relay distance settings by the ANFIS method were: Zone 1 = 0.432 Ω, Zone 2 = 0.65 Ω, and Zone 3 = 1.22 Ω. The previous values of relay distance settings by PLN were Zone 1 = 0.587 Ω, Zone 2 = 1.046 Ω, and Zone 3 = 1.766 Ω.]]>
