Abstract

Turbin angin adalah alat yang mengubah energi mekanik menjadi energi listrik, dengan bilah sebagai salah satu komponennya. Tujuan dari penelitian ini adalah untuk menganalisis pengaruh twist (sudut puntir) dan chord (lebar) terhadap coefficient of power (Cp) dengan linierisasi pada tiap elemen bilah. Metode yang digunakan dalam penelitian ini adalah metode simulasi dengan menggunakan perangkat lunak. Tujuan yang ingin dicapai pada penelitian ini adalah menemukan desain terbaik dengan metode linierisasi twist dan chord serta mengaplikasikan desain tersebut dalam sebuah rancang desain, dimana hasil akhirnya akan didapat grafik coefficient of power (Cp) atau efisiensi dan tip speed ratio (TSR). Hasil penelitian ini telah dilakukan menunjukkan bahwa optimasi desain bilah turbin angin tipe taper dengan airfoil NREL’s 822 memiliki maximum twist sebesar 6,59 hingga minimum twist 0,12 serta maximum chord sebesar 0,107 meter dan minimum chord sebesar 0,015 meter. Pada proses simulasi tersebut menghasilkan efisiensi sebesar 48% pada TSR 8.

Abstract

Blended learning using Google Classroom is a combination of face-to-face and online learning that utilizes the Google Classroom platform to facilitate interactions between students and teachers outside the classroom. This study aims to assess the effectiveness of implementing blended learning using Google Classroom. The study employs a quantitative method with a descriptive research design. It involves 27 students from the Grade XI Industrial Mechanical Engineering program at SMK Negeri 1 Sumatera Barat. Data collection was conducted through questionnaires and documentation The questionnaire in this study assessed five aspects: the use of Google Classroom, interaction in learning, technological accessibility, comfort and satisfaction, and the effectiveness of blended learning. The analysis results for each assessed aspect were as follows: the use of Google Classroom at 76.66%, interaction in learning at 71.29%, technological accessibility at 75.37%, comfort and satisfaction at 70.74%, and the effectiveness of blended learning at 68.51%. This indicates that students’ overall response to the effectiveness of blended learning using Google Classroom was 73.19%, categorized as effective.

Abstract

Centrifugal fans play a significant role in industrial ventilation systems. Their performance is affected by aerodynamic losses such as flow separation and non-uniform pressure distribution, thereby reducing the overall efficiency. Since design parameters influence the fan efficiency, design parameter optimization becomes one option for addressing this issue. Some optimization methods involve high computational cost and complex procedures. This raises the necessity for a more efficient and systematic optimization procedure. The aim of this study is to propose an integrated approach which involves Computational Fluid Dynamics (CFD) and the Taguchi method to improve the performance of a centrifugal fan. CFD is used to evaluate the performance of different design combinations, while the Taguchi method is used to optimize design parameters. The investigated design parameters are the inlet blade angle (β1), the outlet blade angle (β2), the number of blades (n), and the flow rate (Q). Each of the design factors has three levels, therefore, an L9 orthogonal array was utilized as the design of experiments. Analysis of variance (ANOVA) is used to determine their relative significance. The results show that the optimal combination of design parameters increase the efficiency from 39.79% (the reference) to 63.26%. The CFD simulations for the optimal combination exhibit the improved flow behaviour, which explains the enhanced efficiency. The results show the feasibility of the proposed method for improving the performance of the centrifugal fan.

Abstract

The quality of school education is driven by several factors. These factors encompass school-related elements, pedagogical approaches, learning processes, environmental influences, learning facilities, and the allocation of learning time. It is evident that facilities and infrastructure represent a significant factor in the achievement of students. At SMK Negeri 1 West Sumatra, the Shielded Metal Arc Welding technique subject is used as the criterion for the completion of class 11 students. However, observations indicated that student academic outcomes were not ma11mized. This study explores the correlation between the availability of workshop infrastructure and the academic performance of Class 11 students enrolled in the SMAW (Shielded Metal Arc Welding) technique at SMK Negeri 1 West Sumatra. The investigation employs a correlational method to analyse the data. This study's population comprises 25 students enrolled in the 11th grade Welding Engineering programme, who utilise the Total Sampling Technique. The findings of the product moment correlation analysis demonstrate that the calculated r value of 0.595 exceeds the r table value of 0.396. It is evident that, with a statistical significance at p = 0.001, lower than 0.05, the alternative hypothesis (Ha) is confirmed. Considering the study’s findings, the alternative hypothesis (Ha) is accepted, signifying a robust correlation between workshop facilities and learning achievement. The findings of the analysis yielded a coefficient of determination of 35.4%, indicating that the impact of workshop facilities on student learning achievement is 35.4%. Conversely, a residual of 64.6% is attributed to external factors that were not considered in the study.
