Abstract

Indonesia is an agricultural country with the potential to grow many plants as natural fiber sources. In order to improve its properties, natural fiber needs to be treated by applying nanomaterial so that it can compete with the characteristics of synthetic fibers. The study aims to determine the influence of adding titanium dioxide (TiO2) nanoparticles on pineapple leaf fiber (PALF) characteristics. The PALF was collected from the Subang plantation (Indonesia). The chemical treatment was carried out with pre-treatment using an alkalization process for 3 hours, and the oxidation process was carried out with TEMPO. TiO2 nanoparticle grafting was carried out by adding a silane solution with a ratio of 1:10 with alcohol. The characteristics of PALF were observed using XRD, FTIR, SEM, and tensile tests. The results show that the crystallinity of the PALF increased after TEMPO treatment. PALF form Si-O-C bond identified at a wavelength of 1158 cm-1 after silane treatment. Ti – O – Si functional groups were identified in the 660 cm-1 – 670 cm-1 wavelength range. In the fiber surface, agglomerated TiO2 nanoparticles are formed and increase with increasing TiO2 nanoparticle concentration. The tensile stress of treated PALF is increased by 125%, with the highest tensile strength of 1279.18 MPa, obtained by TiO2 nanoparticle concentration of 1.0%.

Abstract

Solid welding has always been concerned with probe design, pins, and joint strength. Many researchers have conducted studies on joints, such as butt joints, lap joints, and T joints, but the results show low strength. This study analyzes the mechanical properties of a new design of a 90o angle joint joined by friction stir welding. This study connected aluminum 6061 using the friction stir welding method using a rectifying jig and a probe with EMS 45 material. The corner joint designs used corner-lap 45 with feed rate as independent variables in 6, 8, 10, 15, and 30 mm/min and dependent variable probe rotation speed at 1000 rpm and shoulder pressure in 584 kg. The results show low feed rates create chips and fish fins on the advancing side, and microstructure test results at low feed rates (6-15 mm/min) indicate the presence of interface bonding. The hardness value of the stir zone also shows an insignificant increase. In the tensile test results, the tensile strength decreases from the base metal value, which then the tensile strength increases along with the increase in feed rate up to a feed rate of 15 mm/min and decreases again at a feed rate of 30 mm/min.

Abstract

Bacterial cellulose (BC) is a widespread, low-cost biopolymer that has generally been produced from plants and biomass waste. A method for improving the range of applications for bacterial cellulose is adding graphene material. It has an outstanding feature that can increase the performance of nanocomposite materials. The research aims to observe the effect of graphene on the surface morphology, crystallinity, chemical bonding, and tensile strength of BC/CuO nanocomposite. For this study's synthesis, BC was synthesized by fermenting pineapple peel extract for 10 to 14 days. The produced BC was crushed, homogenized with a nano homogenizer machine, and filtered. Filtered BC, CuO, and graphene were added to obtain a solution, and the mixture was first stirred magnetically, followed by an ultrasonic homogenizer, and finally dried using a freeze-dry method to make a porous nanocomposite. According to SEM analysis, the addition of CuO and graphene can fill porosity nanocomposite. By XRD analysis, the addition of graphene reduces the crystallinity of BC/CuO. The FTIR data showed that adding graphene reduces hydrogen bonding and makes some Cu-O-C bonding. The tensile test has demonstrated that the tensile strength of BC-based nanocomposite with graphene reinforcement tends to decrease.

Abstract

Indonesian pineapple production can reach 200 tons per day; however, pineapples generate a significant amount of waste. Pineapple peel waste can be used to make membranes. Composite membranes containing TiO2 have dense properties, low porosity, and increase the mechanical strength of the cellulose sheet. This research uses various ultrasonic homogenizers to homogenize the distribution of nanocellulose and TiO2 (50% and 100% power with 30, 60, and 90 minutes). The casting method is used to shape the membrane. The SEM test shows that the higher the power used and the longer the sonication time, the less agglomeration of about 1.63%/ cm2 and a thickness of 16.56 µm. Identification of X-ray diffraction (XRD) results shows that sonication treatment for too long causes the peak at an angle of 25o to disappear. The analysis revealed no new peaks in the diagram pictures that were found using Fourier Transform Infrared Spectroscopy (FTIR) to analyze the functional groups, but it is known that changes occur in the O-H bonds of cellulose and C=C. The 50% sample with a power of 60 minutes had the lowest roughness value of 1.008 µm. Furthermore, as the power and time on the sample are increased, the roughness increases.

Abstract

Water quality is an important factor in aquaculture activities, including goldfish (Carassius auratus) farming. One approach to improving water quality is the use of nanofilters. This study aims to evaluate the performance of nanofilters made from Sargassum sp. with the addition of copper oxide nanoparticles. The method used involves the fermentation of bacterial cellulose from Acetobacter xylinum using Sargassum sp. extract as a medium, followed by homogenization and the addition of CuO-NPs at concentrations of 0.5%, 1%, and 1.5%, and subsequent oven drying. The nanofilter membrane will then be analyzed using SEM, XRD, and FTIR to characterize its properties. Performance tests will assess the quality of water used in goldfish farming, including pH, TOM, TDS, and TSS after treatment with the nanofilter. Morphological results show a rougher and denser surface with dispersed CuO-NPs. Characterization reveals cellulose I with crystallinity values ranging from 86.80% to 90.20%, with functional group peaks at 3145, 2927, and 1735 cm⁻¹ indicating cellulose characteristics, and a peak at 424 cm⁻¹ indicating Cu-O bonds. Statistical analysis of performance tests on the water quality of goldfish farming in the F-test shows significant differences (p

Abstract

Penelitian ini bertujuan untuk menganalisis struktur mikro baja ST 60 setelah perlakuan pengerasan (hardening) dengan menggunakan variasi media pendingin. Baja ST 60 dipilih karena aplikasinya yang luas dalam industri konstruksi dan mesin, yang membutuhkan sifat mekanik tinggi seperti kekerasan dan ketangguhan. Proses hardening dilakukan dengan memanaskan baja hingga suhu austenisasi (850–900°C), diikuti dengan pendinginan cepat menggunakan tiga media berbeda, yaitu air, oli, dan larutan garam. Struktur mikro hasil perlakuan dianalisis menggunakan mikroskop optik untuk mengidentifikasi fasa-fasa yang terbentuk, seperti martensit, ferit, dan perlit. Hasil penelitian menunjukkan bahwa variasi media pendingin memiliki pengaruh signifikan terhadap struktur mikro dan sifat mekanik baja ST 60. Pendinginan menggunakan air menghasilkan pembentukan martensit yang lebih dominan, meningkatkan kekerasan namun berpotensi menyebabkan retakan. Pendinginan dengan oli menghasilkan struktur campuran martensit dan perlit dengan kekerasan sedang serta retakan yang lebih minim. Sementara itu, pendinginan dengan larutan garam memberikan hasil serupa dengan air, namun dengan distribusi martensit yang lebih seragam. Penelitian ini mengungkapkan bahwa pemilihan media pendingin yang tepat sangat penting untuk mengoptimalkan sifat mekanik baja ST 60 sesuai kebutuhan aplikasinya.

Abstract

Simulation analysis and quantitative approaches have become very important in the foundry industry to improve product quality and minimize defects. This study aims to analyze macro defects, particularly porosity, in ashtray patterns produced through sand casting. A quantitative approach was used to identify and evaluate macro defects in the castings by utilizing 3D simulation techniques. This process involves taking macro images of the molded samples and then processing them to determine the porosity level. The porosity evaluation was carried out by comparing the simulation results with experimental data, thus enabling a more in-depth understanding of the factors affecting casting quality. The results of this study show the porosity formed by 3-dimensional simulation and the porosity percentage derived from statistical interpretation of macro photographs of sand casting materials. The findings are expected to make a meaningful contribution to the foundry industry, particularly in the effort to improve product quality through process optimization. This study also highlights the importance of quantitative and simulation approaches in analyzing and predicting casting defects, which can ultimately reduce production costs and improve product yield.
