The motivation behind the selection of zeolite was due to its high cation exchange capacity (CEC) and ability to retain moisture. A study was conducted to determine the impact of zeolite and rockwool on the growth and leaching analysis of lettuce in a drip hydroponic system. The lettuce obtained fertilization through a nutrient solution that contains both macro and micronutrients. The solution's electrical conductivity (EC) ranged from 1.2 to 1.9 dS/m, with a pH of 5.75 and a temperature of 30-32 ºC. Based on the study on lettuce growth, an additional amount of zeolite in the rockwool system resulted in an increase of 11.48% in stem diameter, 5.13% in root weight, 25.5% in dry root weight, 20% in shoot weight, and 20.23% in dry shoot weight, as compared to rockwool only. However, there were no changes in lettuce height and leaf diameter identified. Based on the analysis of the hydroponic wastewater solution, the concentration of nitrate, nitrite, and ammonia ions decreased by 41.17%, 50%, and 75%, respectively, in the presence of zeolite in rockwool system compared to rockwool only. The presence of zeolite has a significant impact on reducing the concentration of nitrate, nitrite, and ammonia ions, however, it has a minimal effect on the growth of lettuce’s height and leaf diameter.</p> Norsuhailizah Sazali Mohd Syafiq Masduqi Mohd Zainudin Ashmal Abid Mohamad Radzi Muhammad 'Ali Hashim Muhammad Lutfi Mohd Rizal Desmarita Leni Copyright (c) 2024 International Journal Of Technical Vocational And Engineering Technology https://creativecommons.org/licenses/by-nc-sa/4.0/ 2024-10-31 2024-10-31 5 2 39 46 Implementation of Multi-Hop Communication in Wireless Sensor Network for Flood Early Warning Monitoring System https://journal.pktm.com.my/index.php/ijtvet/article/view/183 <p>A system has been created for a flood early warning monitoring system using LoRa-based multi-hop communication based on several limitations that LoRa has in its implementation of single-hop communication and end devices are located in dark spots or areas that are difficult to reach by the network. The research method starts with creating sensor nodes, relays, and gateways and measuring system performance. The results of system performance measurements are shown by the highest average RSSI value for multi-hop communications being -56.6 dBm at a distance of 20m and the lowest being -85.2 dBm at a distance of 300 m. Meanwhile, the highest average RSSI value for single-hop communication was -79 dBm at a distance of 20 m and 50 m and the lowest was -85.2 dBm at a distance of 150 m. The PDR value in multi-hop communication is 100% up to a distance of 300 m and the PDR value in single-hop communication is 100% up to a distance of 150 m, while in multi-hop communication it is 100% up to a distance of 600 m.

However, cutter weariness is a major problem that can affect the quality of milling and production costs. This is because a prolonged cutting process can cause gradual damage to the cutter's eye due to repeated friction between the cutters and the treated material. Therefore, the study aims to analyze the weariness of the HSS cutter during the ST 60 milling process by using a domain frequency vibration signal approach and periodic weight measurement of the cutter to monitor its weariness. The method to be performed in this study is to perform a milling operation on the ST 60 material using a HSS cutter as well as recording the vibration signal and measuring the cutter's weight at each experimental interval. The result of the vibration signal recording will be processed using Fourier transformation (FFT) to monitor vibration frequency changes that reflect cutter damage. It is hoped that this research will provide a deeper understanding of the mechanisms of HSS cutter depletion, thereby improving the quality of the result and optimizing the cutting conditions to slow the rate of the device.</p> Elvis Adril Asmed Yuliarman Maheka Restu Araliz Afif Elqudsi Copyright (c) 2024 International Journal Of Technical Vocational And Engineering Technology https://creativecommons.org/licenses/by-nc-sa/4.0/ 2024-10-31 2024-10-31 5 2 56 70 Design of Defect Detection Tools in Through Hole Technology (THT) Solder Joints with Classification Based on Deep Learning https://journal.pktm.com.my/index.php/ijtvet/article/view/187 <p>A tool has been created for soldering defect detection to reduce the processing time for testing the quality of solder joints for THT PCBs in soldering practical activities at the Padang State Polytechnic.
