Abstract

The primary goal of this research is to identify and evaluate the most suitable thin-layer drying model to effectively interpret the drying characteristics of banana chips and determine moisture diffusivity at different drying temperatures. The study utilized physiologically mature “kapok” bananas from the local market in Jember Regency. A flash dryer with a 4000-watt electric heating system was used, equipped with a blower for air circulation, an exhaust fan to expel water vapor. The bananas were processed into chips with a thickness of 1 mm. A total of 2000 g of banana chips were dried at constant temperature according to treatment conditions (air velocity 3.2 m/s, drying at temperatures of 60, 70, and 80°C). The study found that higher drying temperatures (80°C) achieved the highest initial drying rate (35.9% in 30 min) compared to 60°C (28.0%) and 70°C (22.0%). However, the drying rate gradually decreased at all temperatures. The drying kinetics of banana chips at 60, 70, and 80°C aligned well with the modified Midilli model. Effective moisture diffusivity values for banana chips at 60, 70, and 80°C were 4.947E-9 m²/s, 5.165(10–9) m²/s, and 5.756(10–9) m²/s, respectively, indicating that drying at 80°C was the most effective. The effective moisture diffusivity value showed a strong correlation with air velocity, drying temperature, material thickness, RH, and specific material attributes. Keywords: Banana, Diffusivity, Drying, Thin layer drying, Modified Midilli Model.

Abstract

The purpose of designing the layout of the facility is to make effective use of space, minimize material handling, expedite the production process and increase the effectiveness of the use of labor. This research method is to use the BLOCPLAN method. This method can help design the layout of the mocaf flour production facility by providing an alternative layout by taking into account the space to be mapped and the inter-departmental/room interrelationships contained in the Activity Relationship Chart (ARC). The results obtained are a factory capacity of 2.5 tons/day, the number of machines needed is 13, the area needed for the mocaf flour factory area is 1.107 m2 with 8 departments/rooms. There are 20 alternative layouts resulting from the BLOCPLAN software, the proposed layouts are selected based on the R-Score value close to 1, namely layout 19.

Abstract

Teknologi penggorengan vakum diminati karena sistem hemat minyak dan produk berkualitas tinggi yang tahan lama. Produksi yang lancar memerlukan perawatan dan keandalan mesin untuk mengurangi kemacetan dan memastikan ketahanan sistem. Analisis akan melibatkan pengukuran nilai MTTF, MTTR, probabilitas kelangsungan hidup, ketersediaan, dan laju kegagalan pada 4 komponen. Berdasarkan analisis mesin penggoreng vakum, terdapat 4 komponen yaitu : ruang penggoreng, pompa vakum, kondensor, dan unit pemanas, dengan kinerja keandalan sebagai berikut: (a) Nilai MTTF untuk ruang penggoreng, pompa vakum, kondensor, dan unit pemanas masing-masing adalah 549 jam, 961 jam, 495 jam, dan 915 jam. (b) Nilai MTTR untuk ruang penggoreng, pompa vakum, kondensor, dan unit pemanas masing-masing adalah 45 jam, 9 jam, 16 jam dan 24 jam. (c) Nilai probabilitas kelangsungan hidup untuk ruang penggoreng, pompa vakum, kondensor, dan unit pemanas masing-masing adalah 76% dan 58%, 96% dan 37%, 98% dan 45% dan 92% dan 27%. (d) Nilai ketersediaan untuk ruang penggoreng, pompa vakum, kondensor, dan unit pemanas masing-masing adalah 92%, 99%, 96% dan 97%. (e) Nilai laju kegagalan untuk ruang penggoreng, pompa vakum, kondensor, dan unit pemanas masing-masing adalah 0,001/jam, 0,001/jam, 0,002/jam dan 0,001/jam. Penelitian ini memberikan gambaran mengenai keandalan dan kinerja mesin, yang penting untuk memastikan kelancaran produksi.
