Abstract

Telecommunication Network Tower is a tower made of a series of iron profiles or rectangular or rectangular pipes, or rectangular long pipes intended to accommodate antennas and radio transmitters and receivers of telecommunications and information waves. In principle, BTS towers have the function of connecting network user communication devices to other networks. To support the smooth operation of the network, the building will remain solid and secure for a certain period. Investigation of the feasibility condition of the tower structure is very important to determine the overall condition of the tower structure. The methods used are hammer test, check bolt tightness (torque), measure slope (vertical), grounding, and visual observation. From the results of the test data obtained the average bolt tightness is 432.86 Nm. The tower slope test of 1.90 cm on leg A smaller than 3.6 cm is considered good because it is still within the tolerance limit of the bat slope, the average soil resistance measure smaller than1 ohm used is very good, and the visual physical conditions are very similar, so it can be done Tower in safe and working condition

Abstract

Indonesia is an agricultural country with 40% of the population's livelihood provided by farmers. Harvested rice typically has a moisture content of 20-27% on a wet basis. The type of artificial dryer that is often used is the tub or rotary type. This research aims to develop a rice dryer using a combined tray and rotary-type method. Based on the result, the higher the speed dryer, the shorter the drying time. The net result of this test is that the relationship between time and engine speed is inversely proportional. The higher the speed, the shorter the drying time. The net result of this test is that the relationship between time and engine speed is inversely proportional. Rice drying results can be described as dry, but not including ready-to-eat rice standards. The higher the speed, the shorter the drying time.

Abstract

The development of lighting technology, particularly LED lamps, drives the need for light intensity testing (lumen) to ensure quality and energy efficiency. The SNI IEC 62612:2016 standard establishes testing parameters that must be met, but field testing processes are still largely manual and inefficient. This research aims to design and realize an Internet of Things (IoT)-based lamp lumen value testing tool with results displayed on an Android application as a practical and automated solution. The tool is designed according to the SNI IEC 62612:2016 standard, equipped with a BH1750 sensor to measure light intensity (lux), a PZEM-004T sensor to measure voltage and current, and an MLX90614 sensor to measure lamp surface temperature. The testing process is performed automatically using a NodeMCU ESP32 microcontroller, with measurement results displayed on a 20x4 LCD and transmitted to the Blynk application on Android in real-time. Testing on 16 LED lamp samples from various brands and powers showed that the system has high accuracy with average BH1750 sensor accuracy of 98.78%, MLX90614 sensor accuracy of 99.74%, PZEM-004T sensor accuracy for voltage of 99.9% and current 100%, as well as error-free data transmission to Android applications. This tool successfully performs lumen testing automatically, accurately, and efficiently according to national standards.

Abstract

Lamps have a limited lifetime and may experience performance degradation due to repeated on–off operations (switch cycles). However, most developed testing devices are still focused on recording the number of cycles without integrating real-time monitoring of electrical and temperature parameters within a single Internet of Things (IoT)-based system. This research aims to design and develop an IoT-based lamp switch cycle testing device connected to an Android application through the Blynk platform. The developed system uses an LDR sensor for light detection, a PZEM-004T sensor for measuring voltage, current, and power, and an MLX90614 sensor for temperature monitoring. The ESP32 microcontroller acts as the main control and data communication unit. The tested parameters include switching cycles, temperature, voltage, current, and power, which can be monitored in real-time through an LCD and the Blynk application. The test results show that the 5 W LED lamp achieved 192,395 cycles with an average temperature of 37.5°C, voltage of 221.5 V, current of 0.018 A, and power of 4.03 W. The 9 W TL LED lamp reached 226,039 cycles with a temperature of 31°C, voltage of 221.7 V, current of 0.031 A, and power of 6.64 W. The system is equipped with electrical protection features and an automatic reset mechanism, enabling safe and continuous testing. This research provides an integrated system for evaluating lamp durability and performance characteristics through real-time monitoring of switch cycles, electrical parameters, and temperature.
