Abstract

Shell and tube heat exchangers are essential components in the process industry, utilizing heat from exhaust gases to superheat steam in the production process. Their performance significantly determines the overall energy efficiency of the system. This study presents a case-based novelty by evaluating the actual performance of a shell and tube heat exchanger at PT. XYZ through Computational Fluid Dynamics (CFD) using Ansys Fluent 17.2. Simulations were conducted to analyze the distribution of temperature, pressure, and fluid velocity, as well as to calculate their effectiveness and LMTD. The simulation results show that the temperature of the cold fluid increases from 11.95°C to 19.35°C, while the temperature of the hot fluid decreases from 62.05°C to 49.55°C. The fluid pressure also decreases significantly, from 1717 Pa to -76.48 Pa on the tube side. The LMTD value is 40.09°C, and the heat transfer effectiveness is 24.95%. To ensure reliability, the simulation results were validated against actual operating data from PT. XYZ. This study contributes by providing a representative picture of the real operating performance of shell and tube heat exchangers, which can serve as a practical basis for improving system design and energy efficiency in the process industry.

Abstract

Telah dilaksanakan program penerapan ipteks pelatihan reperasi printer untuk pemuda Gampong Kuala Kecamatan Blang Mangat Kota Lhokseumawe. Reperasi printer merupakan salah satu ketrampilan yang sangat menjanjikan, mengingat jumlah pengguna printer yang terus meningkat dan jumlah tempat reperasi yang terbatas. 11 (sebelas) orang pemuda dan pemudi Gampong Kuala dilatih selama 5 (lima) hari meliputi; cara memasang dan mengintall program printer, cara merawat printer, pengenalan komponen, jenis-jenis kerusakan dan cara reperasinya serta cara pemasangan infus atau Continous Ink Supply System (CISS). Pelatihan diikuti oleh 11 (sebelas) orang peserta. Hasil evaluasi penerapan ipteks menunjukkan bahwa peserta dapat menyerap materi dengan baik, tingkat keberhasilan program mencapai 100% untuk materi pemasangan printer dan menginstal program printer, sementara pengenalan komponen mencapai 53,3%, jenis kerusakan dan cara reperasinya mencapai 50% dan pemasangan infus mencapai 63,6%. Masyarakat yang tinggal di desa memiliki intelektualitas yang dapat diandalkan dan memiliki displin yang baik, hanya saja mereka kurang dalam hal mendapatkan kesempatan. Oleh karena itu dengan dilaksanakannya program penerapan ipteks ini masyarakat memiliki ketrampilan mereperasi printer, sehingga menjadi salah satu alternatif ketrampilan yang dapat membantu meningkatkan taraf hidup mereka.Kata kunci : Printer, reperasi, komponen, ketrampilan.
