Abstract

Despite coffee is one of the leading commodities in Bengkulu Province, the traditional drying process of coffee beans for 10-14 days are still a common practice. This research aims to design, fabricate, and evaluate the thermal performance of a 50 kg capacity wood-fueled coffee drying oven. A three-dimensional CFD model was developed using ANSYS Fluent to analyze temperature distribution within the drying chamber and optimize thermal performance prior to fabrication. Experimental testing was conducted to validate the numerical predictions under controlled operating conditions. The proposed technology is distinguished by its use of locally available biomass fuel. The results of the coffee drying oven simulation, under empty conditions, achieved the desired temperature based. The drying time for coffee beans in this research was 9 hours, achieving a moisture content of 10% to 13% (a moisture content of 12.5% is the Indonesian National Standard. Simulation results predicted chamber temperatures ranging from 67°C to 87°C with an inlet temperature of approximately 100°C, indicating adequate thermal conditions for drying. Experimental measurements showed good agreement with the CFD model, reaching near-steady thermal conditions within 25 minutes.

Abstract

PT XYZ still produces many product defects that exceed the specified permissible limits. This company has a product defect margin of 2.50% of total production. The purpose of this study is to improve product quality by facing fierce competition and become a theoretical reference in suppressing product failures and information to determine its importance using servqual and QFM. Servqual is a service quality measurement method developed by Parasuraman, et al. QFM is a quality management tool to map and identify critical points in the service process that affect quality. The implementation of PDCA in the company needs to be improved again and the implementation of 5R in the company needs to be improved. The largest waste in the Birch 4.6 mm product is Repair with a Press Mark defect type of 0.47% and in the Birch 18 mm product, the highest Fail Reject Defect is a bubble of 3.57%.

Abstract

Perancangan mesin pengemasan pangan membutuhkan analisis yang cermat terhadap pengaruh beban termal dan mekanik, mengingat kondisi operasi dapat menimbulkan konsentrasi panas serta tegangan yang berpotensi mempercepat kegagalan struktur. Penelitian ini bertujuan untuk menganalisis perilaku termo-mekanik mesin press pengemasan makanan menggunakan perangkat lunak ANSYS dengan pendekatan Finite Element Analysis (FEA). Simulasi dilakukan untuk mengevaluasi distribusi temperatur, deformasi akibat beban puntir, serta tegangan ekivalen Von-Mises pada rangka mesin. Hasil simulasi perpindahan panas menunjukkan bahwa suhu maksimum mencapai 85,34 °C setelah 120 detik, dengan distribusi panas yang terlokalisasi pada area sekitar poros tengah, sedangkan bagian rangka utama relatif stabil pada suhu 28 °C. Analisis deformasi memperlihatkan adanya perubahan dimensi lokal di sekitar pusat pemanasan, namun tidak menyebar secara signifikan ke seluruh struktur. Sementara itu, simulasi tegangan Von-Mises mengindikasikan tegangan maksimum sebesar 182,45 MPa pada bagian atas rangka, sedangkan bagian bawah hampir tidak menerima tegangan berarti. Temuan ini menunjukkan bahwa mesin memiliki titik kritis pada area tertentu yang rentan terhadap beban kombinasi termal dan mekanik. Penelitian ini memberikan kontribusi dalam pengembangan desain mesin pengemasan pangan yang lebih andal melalui identifikasi area rawan serta rekomendasi perbaikan struktur.
