Abstract

Bipolar plate is a key component that determines a fuel cell's performance and service life. Carbon-based polymer composite materials were developed as lightweight, easy-to-process alternatives to metal. The use of carbon-based fillers in polymer composites has grown rapidly as an alternative to bipolar plate materials in fuel cell applications, especially to meet performance targets set by the U.S. Department of Energy (DOE). DOE requires high electrical conductivity (≥100 S/cm in the in-plane direction and ≥10 S/cm in the through-plane direction), low density, adequate mechanical strength, and good corrosion resistance and chemical stability. Recent studies have shown that the addition of carbon fillers, such as graphite, carbon black, graphene, and activated carbon (AC), can increase electrical conductivity by forming conductive percolation networks in polymer matrices. This study evaluates the potential of AC from household waste in the form of coconut shells as fillers in polypropylene (PP) composites for bipolar plate applications. AC is synthesized through carbonization and activation processes, then mixed into a PP matrix with PP/AC compositions of 100/0, 90/10, 80/20, and 70/30 percent by weight. The focus of the study is the effect of composition variation on density and bending strength. The test results show that increasing the AC fraction tends to decrease the composite density. The maximum density was obtained at a 90/10 (by weight) PP/AC composition of 0.9 g/cm³, indicating more effective filling of the pore matrix by AC particles. On the other hand, bending strength shows a downward trend. The maximum flexural strength is achieved at an AC composition of 34.58 MPa at 10% weight, indicating optimal dispersion and stress transfer between the matrix and the filler. The addition of AC above the composition causes a decrease in bending strength due to potential particle agglomeration, cavities, and the limited mobility of polymer chains. Electrical conductivity tends to increase with the addition of AC due to the formation of a network of electrical currents between carbon particles within cavities, reaching a maximum of 5 S/cm at 30% by weight of AC. The electrical conductivity obtained showed better improvement than several research results on polymeric materials using the hot-press method, with a value of 1.7 S/cm, using graphite filler materials up to 60% by weight. These findings confirm that AC from coconut shells has the potential to serve as a sustainable filler for fuel cell bipolar plates, with an optimal composition that balances density and mechanical properties.

Abstract

This study aims to optimize biodiesel production from waste cooking oil using ultrasonic technology combined with Response Surface Methodology (RSM). The investigated variables include the methanol-to-oil molar ratio (6–12), alkaline catalyst concentration (1–3 wt%), and ultrasonic reaction time (480–1440 s). Based on 17 experimental runs, a two-factor interaction (2FI) linear regression model was developed. ANOVA results indicate that all variables significantly affect biodiesel yield (p < 0.05), with catalyst concentration as the most influential factor. The model demonstrates high predictive accuracy (R² = 0.937; adjusted R² = 0.900; MAE = 2.24%; RMSE = 2.84%). Optimization results indicate optimal conditions at a methanol-to-oil ratio of 10.96, a catalyst concentration of 1.03 wt%, and a reaction time of 1414.79 s, yielding 96.84% FAME. Ultrasonic technology effectively enhances mixing and accelerates reactions via cavitation. This study provides practical operational guidance to improve the efficiency of sustainable biodiesel production and support carbon emission reduction.

Abstract

This study aims to this study was to examine the effect of polypropylene (PP) plastic and activated carbon (AC) composition in a plastic composite material. The composite material was mixed using an internal mixer at a processing temperature of 220°C and a speed of 50 rpm. The mixture was then molded with dimensions of 100 mm in length, 15 mm in width, and 2,5 mm in thickness. The sample molding was performed using a compression molding method with a pressure of 1500 MPa at 250°C and a holding time of 300 minutes. Subsequently, the samples were cut according to the bending test dimensions following ASTM D790-03 standards, with dimensions of 100 mm x 12.7 mm x 2.5 mm. The test results for the polypropylene-activated carbon composite in the first composition showed a maximum stress point of 36.95 MPa and an elastic modulus of 4.3096 MPa, while the second composition showed a maximum stress point of 34.58 MPa and an elastic modulus of 3.371 MPa. These findings indicate that increasing the activated carbon composition in polypropylene polymer results in a reduction in bending strength.

Abstract

In general, every livestock needs feed in the form of a mixture of livestock feed. The livestock feed fermentation process is currently phenomenal because it provides benefits that are felt by farmers. Maybe many people know the fermentation as a process of making supplement drinks only. It turns out not, the fermentation process can be used as an alternative to making high-quality livestock feed. In addition to being very simple to make, making feed by fermentation also saves time and money, because farmers are no longer busy with herding or grazing. This horizontal mixer machine has a capacity of 100 kg / Batch. In making this machine includes manufacturing processes such as: welding, grinding, drilling, bending, cutting torch or gas cutting, and non-permanent joints, namely nut and bolt joints. The components of the machine are: frame, tube, double screw, axle shaft, bossing, gear box, housing bearing, block bearing, pulley, v-belt, and electric motor. And then assembled and put together into a machine. From the above explanation, the following conclusions can be drawn: 1. Horizontal mixer machine with a tube diameter of 60 cm and a width of 90 cm, is capable of mixing 100 kg/batch of animal feed. 2. Horizontal mixer machine using a double screw produces a more homogeneous mixture compared to using the manual method.

Abstract

This Community Service activity was carried out at the Roti Pakcik Tanjung Morawa MSME through work process observations, discussions with the owner and workers, and recording the condition of the production facility. The activity focused on two fundamental needs of the MSME: improving the layout of the work area to enhance production efficiency and identifying the need for relevant production technology. The observation results showed a crowded work area, unclear functional zoning, and the movement of materials and products across the same area. These conditions increased waiting times, increased the risk of cross-contamination, and complicated quality control. In addition, the production process still relied on manual practices and limited tools, so there was a need for technology in the form of a flour sifting machine to maintain ingredient consistency, a mixer to maintain dough homogeneity according to production capacity, and a bread cutting machine to speed up the process, improve size uniformity, and reduce work fatigue. The activity resulted in a workflow problem map, an initial zoning design, and a list of technology priorities as a basis for further mentoring. These findings position the program as the initial stage of a realistic and field-based MSME production transformation.
