Abstract

The use of external magnetic fields is very influential in TIG (Tungsten Inert Gas) welding because it can disrupt the stability of the electric arc formed between the tungsten electrode and the base metal. Magnetic fields can cause the arc to distort or shift, resulting in uneven and low quality welds. TIG (Tungsten Inert Gas) is a welding method that uses a non-melting tungsten electrode to produce a weld. This study aims to determine the effect of external magnetic field on the quality of TIG welding results. This research uses the TIG (Tungsten Inert Gas) welding process on low carbon steel material with speed variations of 4 mm/s, 6 mm/s, 8 mm/s and 10 mm/s and uses 2 Neodymium type external magnetic fields. Tests carried out on the results of welding joints are Vickers hardness test, micro & macro structure test. The highest hardness test value was obtained in the 4 mm/s welding speed variation using 2 external magnetic fields with a hardness value of 187.388 HVN. Microstructure testing shows that the base metal contains ferrite and pearlite structures. In the HAZ (Heat Affected Zone) area there are ferrite, pearlite and martensite structures. Macro structure testing shows several welding defects, including porosity, imperfect penetration, underfill and irregular surface. The use of two external magnetic fields can affect the results of TIG welding itself, such as deepening the penetration of welding so as to produce a good welding joint. Some things you should pay attention to if you don't want welding defects to occur are paying attention to the distance between the electric arc and the material, and the torch must be parallel to the welding line.

Abstract

Industri kelapa sawit dapat menyebabkan dampak yang buruk bagi lingkungan terkait dengan limbah cair dari industri pengolahan maupun limbah padat dari perkebunan. Limbah padat dari perkebunan kelapa sawit, seperti pelepah sawit, sesungguhnya dapat dimanfaatkan ulang menjadi biochar yang digunakan sebagai bahan pelapis slow-release-fertilizer. Penelitian ini bertujuan untuk mempelajari pengaruh variasi komposisi, bahan pelapis, dan bahan perekat terhadap daya lepas nitrogen pada biochar-slow-release-fertilizer, serta mempelajari kinetika pelepasannya. Variasi yang digunakan adalah rasio biochar/bentonite 20%:80% – 80%:20%, jenis perekatnya asap cair dan minyak jarak, dan jumlah pupuk urea 30% massa total. Hasil penelitian menunjukan bahwa hasil optimum yang diperoleh untuk bahan perekat asap cair dan minyak jarak adalah berturut-turut pada rasio biochar/bentonite 50%:50% dan 60%:40%. Sedangkan hasil uji pelindian mendapatkan bahwa kedua formula tersebut mampu mempertahankan pelepasan nitrogen total hingga 28 hari, dibanding 13 hari untuk formulasi yang tidak dimodifikasi. Uji kinetika pelepasan menggunakan model Korsmeyer-Peppas menunjukkan bahwa mekanisme pelepasan kedua sampel tersebut mengikuti difusi Fickian.

Abstract

Composite is a material that is formed from a combination of 2 or more materials. The orientation of the inclination angle of the webbing on the composite affects the tensile strength value. This research was conducted to determine the effect of variations in the angle of inclination of the webbing and the phenomenon of delamination on the value of tensile strength. The process of making fiberglass woven fiber composites and a mixture of resin and catalyst uses the vacuum bagging method. The variations used in this study are the angle of inclination of the webbing 0°, 15°, 30° and 45°. Tensile test specimens using the ASTM D638 standard. The specimens that have been cut will then be perforated with a diameter of 4 mm using a milling machine. Tensile testing was carried out using a Universal Testing Machine. The highest tensile strength value is at an angle of 0° with a value of 189.30 MPa and the lowest tensile strength is at an angle of 45° with a value of 34.25 MPa and for the value of the delamination factor has little effect on the value of tensile strength.

Abstract

SS400 carbon steel is a type of low carbon steel that has low surface hardness, wears easily, and is not resistant to impact. The application of cladding can reduce the risk of material failure due to the weakness of SS400 carbon steel. In this study, cladding was performed by SMAW method using HV-600 electrodes and a current of 115 A. This welding process causes heat to be concentrated in the melting area, resulting in uneven heating and cooling, so preheating is necessary. This study aims to evaluate the effect of preheating temperature variations of 200°C, 300°C, 400°C, and non-preheating on microstructure and hardness in the cladding process. Macro structural testing shows that the application of preheating can minimize the occurrence of welding defects, and an increase in preheating has an effect on increasing the depth of the HAZ in each specimen tested.  Microstructure testing shows that the application of higher preheating will form more ductile phases in the base metal, diffusion layer, HAZ areas. The base metal area has pearlite and ferrite phases. The diffusion layer shows clear boundaries as a result of the diffusion process. The HAZ section forms a fine pearlite microstructure and coarse pearlite and ferrite phases. The weld metal layer is not affected by the preheating temperature used, there are martensite and ferrite phases. Hardness testing on 200oC preheating specimens has the highest hardness in the weld metal of 680.11 HV. Hardness in the diffusion layer, HAZ, and base metal which shows that an increase in preheating temperature affects the decrease in the hardness value of the specimen.

Abstract

NaOH immersion treatment on hemp fiber is very important in making composites. This is because natural fibers still contain materials such as lignin and hemicellulose so hemp fibers are cleaner and can provide strong fiber and resin attachment. The aim of this research is to find out how the best time for soaking in NaOH for hemp fiber compares to the tensile strength of hemp fiber composites. The materials used are polyurethane and hemp fiber. The research focused on variations without treatment, 2 hours, 3 hours, 4 hours, and 5 hours with a percentage of 5% NaOH and dried under direct sunlight after soaking. Composite manufacture was carried out using the compression molding method for 24 hours with a pressure of 5 bar. Tensile testing was also used in this research with reference to the ASTM D 638 standard. The fiber surface experiences changes in shape such as cleanliness, color and fiber structure which are different in each variation. It should be noted that the maximum tensile strength is 11,597 MPa at 4 hours of immersion, and the lowest tensile strength is 6,054 MPa at 5 hours of immersion. Then the lowest modulus of elasticity value is found in the variation without treatment at 0,049 GPa. The highest value of elastic modulus is found in the 4 hour variation with a value of 0,076 GPa.
