Abstract

Metal recycling is an effective way to deal with the abundance of scrap metal such as drink can, scrap iron and others. Metal recycling skill is needed by the community especially in the youth to help reduce the amount of scrap metals in the environment and to develop a new creative and innovative industry, however the community doesn’t have the skills needed and have never gotten the training on metal recycling. Therefore, in the community service acticity of the Materials and Metalurgical Engineering Study Program, ITK, it was given metal recycling skill (aluminum) for the community. The metal recycling skill training was held in Kalimantan Institute of Technology campus, Balikpapan, East Kalimantan. The training was attended by 15 people from the community. The training was held by conducting presentation, practice, and discussion. The qualitative analysis results (from observation and discussion result) showed that all participant felt getting new knowledge and skill, that is the metal recycling skill.

Abstract

One that can be used as an organic inhibitor is bawang tiwai leaves extract. This study used 3.5% NaCl as corrosive media with inhibitor concentration of bawang tiwai leaves extract from 0 ppm to 500 ppm and immersion time from 10 days up to 30 days. The efficiency of inhibition was measured using a weight loss corrosion test, while the corrosion rate was obtained from polarization measurements. The FTIR test results show that the extract contains flavonoid compounds that act as antioxidants and inhibit corrosion. Inhibitory efficiency achieved up to 95.4545% for the addition of 300 ppm inhibitor and 20 days of immersion time. This inhibitory behavior is also supported by polarization measurements where the lowest corrosion rate of 0.00128 mm/year is obtained at the same concentration and immersion time.

Abstract

This research studied about making hard capsule shell using glucomannan extract from salak seed (Salacca edulis Reinw.). The glucomannan extracted by using etanol 96% and aqua dm. The glucomannan that had been extracted will became KGM polymer that will be used for casting the hard capsule shell using petri cup. The results obtained by smashing the seeds of salak to be smooth with meat grinder and glucomannan extraction using 2 methods with etanol 96% and isopropyl alcohol. After extracting the seeds of salak seeds, the bacon seed flour is weighed and taken some samples to obtain the best composition, resulting in a film layer on a thick capsule shell like a capsule shell in general. The result of the printing on the petri cup is still a thin layer that can not be taken, but this proves that glucomannan contained in the seeds of salak able to produce lapisal film capsule shells with the right composition.

Abstract

Welding is a metal joining process with filler or without filler. The welding method is also used to thicken the surface of the material or hardfacing. Hardfacing is a welding process with the aim of improving mechanical properties and is used on worn components by using SMAW welding, SMAW welding is used because it is relatively inexpensive and flexible. The purpose of this study was to determine the effect of hardfacing with SMAW welding direction variations on the tensile strength and microstructure of ASTM A36 steel material. The welding directions are horizontal, vertical and diagonal. This study used ASTM A 36 steel with a thickness of 5 mm. The welding electrode was E7018 with a diameter of 3.2 mm and a current of 130 A. After conducting this research, the highest average tensile strength value was found in the vertical direction, which was 474.74 N/mm2. The average value of the tensile strength in the diagonal direction is 446.715 N/mm2. The average horizontal tensile strength value is 420.785 N/mm2.

Abstract

In synthesizing Fe3O4 nanoparticles using the green synthesis method by adding FeCl3.6H2O and pineapple leaf extract. Pineapple leaf extract is used as a natural reducing agent which contains hydroxyl and carbonyl, which acts as a reducing agent for the synthesized FeCl3.6H2O. Then after the precipitate is obtained, calcination will be carried out, where the calcination temperature in the synthesis becomes a factor in forming Fe3O4 nanoparticles. Different calcination temperatures of 400°C, 450°C, and 500°C were given to prepare Fe3O4 nanoparticles, with the XRD test results confirming that Fe3O4 nanoparticles were formed. In the SEM-EDX test, the optimum variation is 400°C because the average particle size is 150.23 nm with irregular particle shapes. Then proceed with the SAA results with a surface area of 60.125 m²/g. Nanomagnetite produced by green synthesis of pineapple leaf extract can be used as a removal dyes.

Abstract

Desa Sebakung di Kabupaten Pasir, Provinsi Kalimantan Timur memiliki luas wilayah sekitar 3,94 km² dengan jumlah penduduk sekitar 1.415 jiwa. Salah satu permasalahan di desa Sebakung adalah rendahnya minat baca masyarakat yang disebabkan oleh kurangnya akses terhadap bahan bacaan yang memadai dan minimnya kesadaran dan budaya membaca di kalangan masyarakat desa Sebakung. Untuk mengatasi permasalahan minat baca di desa Sebakung, maka dilakukan pengembangan taman bacaan desa melalui beberapa tahap. Pada tahap persiapan dilakukan dengan melakukan survey dan observasi ke Desa Sebakung. Pada tahap pelaksanaan dilakukan dengan beberapa kegiatan seperti mempersiapkan peralatan untuk pengembangan taman bacaan, penerapan teknologi tepat guna (TTG), dan melakukan sosialisasi dan kampanye untuk meningkatkan kesadaran dan budaya membaca di Desa Sebakung. Selanjutnya, tahap evaluasi dilakukan dengan menganalisis minat baca anak-anak melalui jumlah kunjungan ke taman bacaan selama 12 minggu dan diperoleh grafik yang stabil. Dari hasil tersebut dapat disimpulkan bahwa terjadi peningkatan minat baca gen-z di Desa Sebakung melalui program ini.

Abstract

Amodiaquine (AQ) is an essential medicine in treating malaria. Yet, the threat of drug resistance and toxicity necessitates accurate measurement of AQ in the human body. This research determines the amodiaquine (AQ) detection performance of boron-doped diamond (BDD) working electrodes. The study utilizes different pulse velocity (DPV) methods to analyze the AQ reaction behavior of BDD. The research demonstrates the reaction mechanism: Two electrons are transferred, and irreversible oxidation reactions occur. The sensor limit of detection (LOD) is measured to determine the performance of working electrodes for AQ detection. The LOD is calculated between 0.0645 µM and 0.3 µM, and changes in analytical concentrations relative to maximum current are calculated. The LOD of the BDD electrode is 1.5×10–8 M, lower than previous research on AQ sensors, showing the effectivity of the BDD electrode as an AQ sensor.
