mahardika2525@gmail.com Sri Wahyu Suciyati ayoe1971@gmail.com Amir Supriyanto amirsupriyanto65@gmail.com Gurum Ahmad Pauzi gurum@fmipa.unila.ac.id <p><em>This research has realized the design of a smart green trash box based on the HC-SR04 sensor, which is integrated with Arduino Uno. This research aims to design and build a digital instrumentation system based on Arduino Uno, applying Ultrasonic Sensors to the Green Box Trash System. In addition, this system is equipped with an information display via LCD and speakers so that we can find out the contents of the green trash box. Data retrieval by detecting objects with a distance of less than 10 cm to open the trash and measure the volume in the green trash box. The research results are displayed as a prototype Smart Green Trash Box design. Based on the Hc-Sr04 Sensor Integrated by Arduino Uno. The ultrasonic sensor in the Green Box Trash system works well by measuring the volume and can detect when an object is approaching with a distance of less than 10 cm. Assembling the green box using the HC-SR04 sensor, which is integrated with Arduino Uno functions according to the program created if, in the green box, there is HC-Sr04 1 sensor trash, it measure the volume of trash and then display it through the LCD, and if there is an object approaching the HC-Sr04 sensor 2, then the servo moves so that the green trash box can be opened. The Green Trash box can display trash volume and time on the 16x2 character LCD in real-time with the program uploaded to Arduino as monitoring.</em></p> 2023-09-16T00:00:00+00:00 Copyright (c) 2023 http://jemit.fmipa.unila.ac.id/index.php/jurnal/article/view/125 The Effect of Immersion Time on Corrosion Rate on St37 Carbon Steel in 3% NaCl Corrosive Medium Using Waru Leaves Extract Inhibitor 2022-04-21T02:44:20+00:00 Fredison Dian Sinaga fredisondian7@gmail.com Ediman Ginting Suka ediman.ginting@fmipa.unila.ac.id Pulung Karo Karo pulung.karo@fmipa.unila.ac.id <p><em>The research of effect of immersion time on the corrosion rate of St37 carbon steel has been conducted in a 3% NaCl corrosive medium using a hibiscus leaves extract inhibitor. The samples of carbon steel St37 were immersed in a corrosive medium of NaCl 3% without being given and given the inhibitor of hibiscus leaf extract with a concentration of 15% for 3, 6, 9, and 12 days. Calculation of reduction in corrosion rate is carried out by the weight loss method. The results showed that adding the hibiscus leaves extract inhibitor effectively reduced the sample's corrosion rate with the most excellent efficiency at nine days immersion, which was equal to 78,48%. The results of XRD characterization show that the phase formed is pure Fe is a corrosion product. The results of SEM characterization showed that the surface microstructure of the sample after immersion was cracks, holes, and lumps, which indicated that the sample had been corroded. The results of EDS characterization show that in the soaked sample, there were corrosion products in the form of FeO compounds whose magnitude increased with every immersion.</em></p> 2023-09-16T00:00:00+00:00 Copyright (c) 2023 http://jemit.fmipa.unila.ac.id/index.php/jurnal/article/view/167 Effect of Variation of Concentration of Ketapang (Terminalia Catappa) Fruit Extract on The Corrosion Rate of ASTM A36 Iron 2022-10-24T05:47:36+00:00 Ocean Prabowo oceanprabowo@gmail.com Syafriadi Syafriadi syafriadi@fmipa.unila.ac.id Ediman Ginting Suka ediman.ginting@fmipa.unila.ac.id <p><em>The aim of this study was to investigate the influence of varying concentrations of Terminalia catappa fruit peel extract on the corrosion rate during immersion periods of 2 days, 4 days, and 6 days for ASTM A36 steel. The ASTM A36 steel specimens were immersed in a corrosive medium containing 2% NaCl, with inhibitor compositions of 0%V, 1%V, 2%V, and 3%V being tested. Measurement results revealed that as the concentration of Terminalia catappa fruit peel extract increased, the corrosion rate proportionally decreased. The lowest corrosion rate was observed in samples with a 3%V inhibitor composition, subjected to a 4-day immersion, measuring at 0.02321 mmpy. Moreover, with the augmentation of fruit peel extract concentration, inhibition efficiency exhibited an augmented trend (83.02% for the 3%V composition, and the lowest at 41.84% for the 1%V composition).</em></p> 2023-09-16T00:00:00+00:00 Copyright (c) 2023 http://jemit.fmipa.unila.ac.id/index.php/jurnal/article/view/174 Production of Nanocellulose from Kepok Banana Peel Waste Using Acid Hydrolysis Method 2022-10-28T04:06:33+00:00 Faradilla Nabila Putri faradillanputri@gmail.com Posman Manurung posman.manurung@fmipa.unila.ac.id Sri Wahyu Suciyati sri.wahyu@fmipa.unila.ac.id Pulung Karo Karo pulung.karo@fmipa.unila.ac.id <p>Research on the production of nanocellulose from kepok banana peel waste has been carried out using the Acid Hydrolysis method with H<sub>2</sub>SO<sub>4</sub> Sulfuric Acid. This study aims to determine the effect of giving H<sub>2</sub>SO<sub>4 </sub>on kepok banana peels and the crystal structure and surface morphology of nanocellulose on kepok banana peels. The production of nanocellulose was carried out in three stages: delignification using 10% NaOH, bleaching using 10% H<sub>2</sub>O<sub>2, </sub>and isolation of nanocellulose using H<sub>2</sub>SO<sub>4 </sub>with various concentrations of 5, 10, 15, and 20%. This research uses X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) as its characterization.

The materials was used in this study were moringa leaf extract, Zn(NO<sub>3</sub>)<sub>2</sub>·6H<sub>2</sub>O with various concentrations of 0.2, 0.4, 0.6, and 0.8 M, and NaOH of 0.1 M. Based on the results of characterization using FTIR, it shows that the functional groups in the content of Moringa leaves play a role in the formation of ZnO nanoparticles. Meanwhile, the results of the XRD characterization showed a diffractogram difference with standard ZnO at concentrations of 0.6 M and 0.8 M Zn(NO<sub>3</sub>)<sub>2</sub>·6H<sub>2</sub>O with the appearance of the NaNO<sub>3 </sub>phase. SEM characterization results show that the morphology of ZnO nanoparticles using the green synthesis method is irregular in shape.</p> 2023-08-31T00:00:00+00:00 Copyright (c) 2023
