Abstract

The double-tube model heat exchanger has a construction of three tube cylinders arranged into one. This model of heat exchanger has a fairly simple construction, making it easier to manufacture and speeding up the manufacturing process. Computational Fluid Dynamics (CFD) is software that can be used to optimize the design and performance evaluation process as well as to speed up the process and minimize costs in tool development because it can represent phenomena that occur in a system. This research aims to analyze air distribution in a double tube model heat exchanger system using CFD analysis and to validate the analysis results with experiments. Based on the research results, a double tube model heat exchanger has been created with an average performance of output temperature and air velocity reaching 97.8oC and 10.4 m/s at a coconut shell fuel consumption of 0.24 kg/minute. The results of evaluating experimental data with simulations obtained RMSE values between 59.33 – 71.69, and MAPE values between 26.26 – 32.93. Meanwhile, the results of the Paired Sample T-Test show that there is no real difference between experimental data and simulation data with an R-value of 0.875 – 0.964. CFD analysis in this research can be used as a reference in the optimization process and development of heat exchangers, especially double-tube models. Keywords: CFD, Design, Double-Tube.

Abstract

Lemon Island is a small island in Manokwari Regency, West Papua. The livelihood of the people on Lemon Island is fishing for captured marine fish. Captured sea fish are prone to damage and spoilage during distribution, and the selling price is also low. Thus, it is necessary to educate the community about the need to process fishery products into fish nuggets to increase the shelf life of fish products and provide information to the community about the diversification of processed fish products. In addition, this community service activity is also expected to increase the income of coastal communities in Manokwari Regency, West Papua.

Abstract

ABSTRACT  Small-scale community-based sago processing in West Papua has high potential, but production at the household level remains limited due to manual processing practices. This community service program aimed to strengthen household sago processing capacity in Sidey Makmur Village, Sidey District, Manokwari Regency through the introduction of a semi-mechanical processing system using a cylinder-type rasping machine (variant-02), training, and on-site technical mentoring. Program performance was evaluated through direct observation of partner operation and production outcomes. The intervention reduced processing time to about 15.5 hours per tree (1 tree per 2 days), achieved rasping capacity of 490 kg/hour, and increased fresh sago starch production from 180 kg/week to 524 kg/week. The results indicate that appropriate technology transfer improves production efficiency, supports operational skill development among partners, and opens greater opportunities for local income improvement. Keywords: community service; Manokwari Regency; sago starch; semi-mechanical processing; technology transfer   ABSTRAK Pengolahan sagu skala rumah tangga berbasis masyarakat di Papua Barat memiliki potensi besar, namun produktivitasnya masih terbatas karena proses yang dominan manual. Program pengabdian ini bertujuan meningkatkan kapasitas pengolahan sagu di Kampung Sidey Makmur, Distrik Sidey, Kabupaten Manokwari melalui introduksi sistem pengolahan semi-mekanis menggunakan mesin pemarut tipe silinder varian-02, pelatihan, dan pendampingan teknis di lapangan. Evaluasi dilakukan melalui observasi langsung terhadap pengoperasian mesin dan capaian produksi mitra. Hasil kegiatan menunjukkan waktu pengolahan sekitar 15,5 jam per pohon (1 pohon per 2 hari), kapasitas pemarutan 490 kg/jam, serta peningkatan produksi pati sagu segar dari 180 kg/minggu menjadi 524 kg/minggu. Kegiatan ini menunjukkan bahwa alih teknologi tepat guna dapat meningkatkan efisiensi proses, memperkuat keterampilan operasional mitra, dan membuka peluang peningkatan pendapatan masyarakat.
