Abstract
Penelitian ini dilakukan untuk merancang dan mengembangkan sebuah tungku pembakaran berbahan bakar LPG yang memiliki efisiensi tinggi, aman digunakan, serta sesuai untuk keperluan praktikum di laboratorium teknik, terutama pada proses penempaan logam. Latar belakang dari penelitian ini adalah tingginya emisi serta rendahnya efisiensi panas pada tungku tradisional yang menggunakan bahan bakar padat, serta keterbatasan dalam mengontrol suhu secara akurat. LPG dipilih sebagai bahan bakar karena sifatnya yang bersih, mudah diatur, dan efisien, sehingga diharapkan dapat meningkatkan performa proses pemanasan. Tahapan penelitian mencakup proses perancangan menggunakan perangkat lunak AutoCAD, pembuatan fisik tungku di laboratorium, serta uji kinerja melalui pengukuran waktu pemanasan dan suhu akhir logam. Desain tungku mencakup penggunaan burner LPG, sistem isolasi panas yang terdiri dari ceramic blanket dan semen tahan api tipe SK-34, serta pengontrol suhu yang menggunakan sensor termokopel. Berdasarkan hasil pengujian, tungku mampu mencapai temperatur sekitar 750 °C, dan jenis nyala api short flame menunjukkan kinerja pemanasan yang lebih cepat dibandingkan long flame. Performa isolasi termal menunjukkan nilai perpindahan panas konduksi sebesar ±2361 W/m². Dari hasil desain dan uji coba yang dilakukan, dapat disimpulkan bahwa tungku berbahan bakar LPG ini layak untuk digunakan sebagai sarana praktikum di institusi pendidikan tinggi. Tungku ini tidak hanya mendukung proses pembelajaran teknik manufaktur secara langsung, tetapi juga memberikan wawasan tambahan mengenai efisiensi energi, pemilihan material isolasi yang tepat, serta aspek keselamatan kerja. Penelitian ini juga dapat dijadikan sebagai rujukan untuk pengembangan tungku termal yang lebih ramah lingkungan dan efisien, baik di dunia pendidikan maupun industri. Kata kunci: tungku pembakaran, gas LPG, efisiensi termal, isolator, nyala api, penempaan. ***** This study was carried out to design and develop an LPG-fueled combustion furnace that is highly efficient, safe to operate, and suitable for use in technical education laboratories, particularly for metal forging processes. The motivation behind the research stems from the low heat efficiency and high emission levels of conventional solid-fuel furnaces, as well as the lack of precise temperature control during heating. LPG was selected as the fuel due to its clean-burning nature, controllability, and energy efficiency, making it a promising alternative for improving the heating process. The research involved several stages, including design using AutoCAD software, fabrication of the furnace in a laboratory setting, and performance testing based on heating duration and final temperature of the metal specimens. The furnace was constructed with an LPG burner, thermal insulation consisting of ceramic blanket and SK-34 refractory cement, and a temperature control system using a thermocouple sensor. The results demonstrated that the furnace could reach temperatures around 750 °C, with the short flame type showing superior heating performance compared to the long flame. Thermal insulation effectiveness was reflected in a heat conduction transfer rate of approximately ±2361 W/m². Based on the design and testing outcomes, it can be concluded that the LPG-fueled furnace is suitable for practical use in higher education institutions. In addition to supporting hands-on learning in manufacturing technology, the furnace also provides valuable insights into energy efficiency, appropriate insulation material selection, and occupational safety. This research may also serve as a reference for developing more efficient and environmentally friendly thermal furnaces for use in both educational and industrial settings. Keywords: combustion furnace, LPG gas, thermal efficiency, insulator, flame type, forging
