Abstract

Oil palm and coconut are important crops in Indonesia that produce vegetable oil. However, both plants also generate a very large amount of waste, one of which is leaves. These leaves are often not utilized optimally and are simply wasted, even though the midrib section has the potential to be used as material for various crafts. This study aims to design and develop a stripping machine for coconut and oil palm midribs using an adjustable blade innovation, which can adapt to variations in midrib diameter to produce clean and optimal strips. The machine utilizes two blades which one adjustable blade for adapting to the midrib diameter and one fixed blade, an AC motor as the main drive, and rubber rollers as the midrib feeder. The outcome of this design is expected to help communities utilize midrib waste more effectively and contribute to increasing the added value of agricultural waste. Furthermore, the use of an adjustable blade mechanism is expected to improve the flexibility and efficiency of the stripping process.

Abstract

Peningkatan volume limbah kepala ikan di Indonesia yang mencapai 30-40% dari total berat tangkapan memerlukan penanganan yang efektif untuk mencegah pembusukan akibat kadar air yang tinggi. Namun, efisiensi mesin pengering rotary drum sering terkendala oleh distribusi panas yang tidak merata dan aliran udara yang kurang optimal. Penelitian ini mengevaluasi kinerja aerodinamika dan termal mesin menggunakan Computational Fluid Dynamics (CFD) dengan membandingkan variasi temperatur (80°C, 100°C, 120°C), diameter pipa (100 mm, 125 mm, 150 mm), dan kecepatan aliran (2 m/s, 5 m/s, 8 m/s). Hasil simulasi menunjukkan bahwa diameter pipa 125 mm menghasilkan aliran yang paling stabil, temperatur 120°C menghasilkan panas yang paling homogen, serta kecepatan 5 m/s menjadi parameter operasional yang optimal untuk menjaga residence time ideal. Secara keseluruhan, kombinasi parameter tersebut merupakan konfigurasi desain terbaik untuk meningkatkan efisiensi energi dan kualitas pengeringan dalam industri pengolahan limbah perikanan.

Abstract

This study presents the design of an organic waste processing device to produce liquid smoke through combustion, particle separation, and condensation processes. The system consists of a combustion chamber, a cyclone separator, and a condensation tube, which were designed and analyzed numerically with software. Dry organic waste such as coconut shells, rice husks, and leaves was used as raw material with a capacity of 15 kg per cycle. Simulation results show that the combustion chamber reached a maximum temperature of approximately 333°C, the cyclone separator achieved flow velocities of 4.72–7.48 m/s with effective particle separation, and the condensation tube reduced the smoke temperature to around 27°C, enabling liquid smoke formation. This device offers potential as a solution for organic waste management while producing valuable by-products such as natural pesticides and organic preservatives.
