Monitoring Pemakaian Daya Listrik KWh Meter Pascabayar Berbasis Internet of Things (IOT)
Get PDFThis study aims to develop a monitoring system for electricity consumption on postpaid KWH meters to enhance efficiency and control of energy usage. Postpaid KWH meters are devices that allow users to pay their electricity bills at the end of the billing period and monitor their energy consumption. However, a major challenge is the lack of an effective real-time monitoring system. In this research, an IoT (Internet of Things)-based monitoring system integrated with postpaid KWH meters is designed. The system uses current and voltage sensors to accurately measure energy consumption. The collected data is then analyzed and displayed through the Blynk application, which allows users to monitor energy consumption in real-time

Get PDFThe aim of this research is for simple home industries or micro, small and medium enterprises (MSMEs) which still use manual noodle dough mixers which require a lot of labor and are not productive. Therefore, a noodle processing machine was designed that uses a motor gearbox as a driver and a Zelio SR3 B101FU programmable logic controller (PLC) control circuit. The test was carried out by connecting the motor gearbox with the Zelio SR3 B101FU programmable logic controller (PLC) control circuit when the weight of the material was ¼ Kg with a voltage of 233 V, the current used was 0.5 A, and it took 10 minutes to obtain the power used to stir the dough. noodle 93.2 W, and the kWh meter per use is 0.01 kWh and the cost used is Rp. 13.52-, when the material weighs ½ Kg with a voltage of 237 V, the current used is 0.5 A, and takes 15 minutes, the power used to stir the noodle dough is 94.8 W, and the kWh meter per use is 0 .02 kWh and the cost used is Rp. 27.04- and when the weight of the ingredients is 1 Kg with a voltage of 232 V, the current used is 0.5 A, and it takes 25 minutes, the power used to stir the noodle dough is 92.8 W, and the kWh meter per use is 0, 03 kWh and the cost used is Rp. 40.56-

Get PDFThis research was conducted to understand gantry cranes as a tool that can accelerate the pace of production which has a significant influence on handling heavy loads, accelerating mobility, and high flexibility in moving workloads to certain areas. The main purpose of this study is to obtain design drawings, calculate construction material requirements, design, conduct weld joint testing with NDT test, and perform loading testing. In achieving this goal, the methods used include data collection, design design, and analysis of the construction strength of the gantry crane frame. The data analysis process uses AutoCAD and SolidWorks software. The result of this study is the design and construction of Gantry Crane equipment which has gone through several strength tests, namely welding joint testing, NDT test (Penetran Test) and loading test that can lift a maximum load of 1 Ton. Thus, this research makes an important contribution in the field of construction and force analysis of gantry crane
Analisa Dan Rancang Bangun Alat Monitoring Keseimbangan Beban 3 Fasa Pada Jaringan Overheat (DL 7901TT) Berbasis Internet Of Things
Get PDFA 3-phase system can experience load balance between phases if the load used is also balanced between the three phases R, S and T. To meet the electrical power needs, there is a distribution of loads which is initially evenly distributed but due to the asymmetry of the ignition times of these loads This creates a load imbalance that impacts the supply of electrical power. This load imbalance between each phase causes current to flow in the neutral. This research uses 4 PZEM-004T sensors and 8 D Lorenzo DL 7901TT input and output monitor modules as readers of current and voltage values for each of the R, S, T and Neutral phases. The ESP8266 NodeMCU is used as a microcontroller which will process sensor reading data displayed in the Blynk application installed in the design box. Based on the IEEE 446-1995 standard, the permitted load unbalance percentage is 5% to 20% per phase. After testing 3 times, the smallest percentage was on the PZEM-004T sensor where the percentage in the 1st experiment was 31.1%, the 2nd experiment was 31.02%, and the 3rd experiment was 31.31% and the percentage comparison The highest analysis imbalance was in the measuring instrument where in the 1st experiment it was 58%, in the 2nd experiment 49%, and in the 3rd experiment it was 50.6%.

Pengaruh Kadar Air Pada Campuran Beton Mutu 25 Mpa Dengan Zat Aditif Master Rheobuild 6
Get PDFConcrete is one of the most commonly used constructoin materials in infrastructure developmen.t concrete has high compressive strenght, is resistant to loads, and has good resistance to weather and the environment. One thing that influences the quantity of concrete is water concrete mixture. This research aims to analyze the effectof water content on the compressive strength of 25 MPa quanlity concrete using the master rheobuild 6 additive. The research method used is laboratory experimental. The test object is a concrete cylinder with a diameter of 10 x 20 cm. The variations in water content used were a reduction of 5%, 10%, 15% and an addition 5%, 10%, 15% with a Master Rheobuild 6 additive dosage of 1,5 of the cement weight. Compressive strength tests were carried out at 7 days, 14 days and 28 days of concrate.
The reseearch results show that the higher the water content, the lower the compressive strength of the concrete produced. At 10% water reduction, the compressive strenght of concrete reaches 33,22 MPa. Meanwhile, at 5% and 15% water reduction, the compressive strenght of concrete is 17,11 MPa and 30,31 MPa respectively. Meanwhile with the addition of 5% water, the compressive strength of the concrete reached 24,16 MPa, while with the addition of 10% and 15%, the compressive strenght of the concrete was around 31,82 MPa and 15,38 MPa respectively. The use of the additive Master Rheobuild 6is able to maintain the slump of the concrete without increasing the water content excessively
Rancang Bangun Mesin Pengayak Pasir Berbasis Arduino Uno Sebagai Speed Control (Programming Section)
Get PDFBased on general observations, many construction workers exert all their physical effort without the support of advanced technology to aid their tasks. One common process encountered in projects performed by workers is the conventional sand sieving process. This study aims to design and build a sand sieving machine based on Arduino Uno, equipped with speed control to minimize operator effort and achieve more efficient use of time in obtaining the desired
sand quality. The sand sieving system utilizes Arduino Uno R3 as the main control unit. Speed control of the motor is achieved using Dimmer SCR Zero-Cross technology.
Additionally, the system includes a stable power supply and 12-volt and 5-volt DC motors as part of the mechanism for changing between coarse and fine sieves. The methods used in this study include designing the speed controller with PID and testing the machine's performance at full and half-speed sieving. Test results show that this sand sieving machine can regulate speed accurately and effectively, providing better efficiency in the sand sieving process
