Shell and Tube Exchanger merupakan salah satu alat penukar kalor dengan memanfaatkan 2 pipa yaitu pipa bagian luar (Shell) dan pipa bagian dalam (tube). Fluida panas mengalir pada bagian dalam, dan fluida pendingin mengalir berlawanan arah pada pipa bagian luar (Shell), sehingga terjadi proses pendingin fluida panas yang mengalir di pipa bagian dalam, yaitu panas dari fluida panas dipindahkan ke fluida dingin yang mengalir. Proses ini berjalan terus menerus. Penelitian ini bertujuan untuk mengetahui penurunan suhu yang di hasilkan oleh penelitian tersebut dengan melakukan variasi jumlah sirip dan mengetahui seberapa besar penurunan suhu yang terjadi pada variasi tersebut menggunakan perpindahan panas pada heat exchanger pipa ganda dengan sirip siku empat. Shell and Tube heat exchanger didesain dengan variasi jumlah sirip yang diletakkan pada pipa dalam (tube) Jumlah sirip yang divariasikan adalah : tanpa sirip, 3 sirip, 6 sirip dan 9 sirip. Dari pengujian ini dihasilkan bahwa penurunan temperatur tertinggi adalah pada sirip yang paling banyak yaitu berjumlah 9, yaitu sebesar 45,3 0C. Penurunan temperatur terjadi dari suhu 800 C menjadi temperatur rata rata 34,70C . Selanjutnya pada sirip berjumlah 6 dari temperatur 8 0 C menjadi temperatur rata rata 40,50 C. Pada sirip berjumlah tiga penurunan temperatur terjadi dari 800C menjadi 45,30C. Sedangkan untuk tanpa sirip, penurunan temperaturnya terkecil, yaitu dari 850C menjadi 47 0C. Dari hasil pengujian didapat penurunan suhu pada alat penukar kalor pipa ganda dengan sirip siku empat,yang dimana dengan ukuran panjang plat 40 cm dan tebal 1,25 mm pengaturan jumlah sirip dan jarak sirip memberikan hasil yang berbeda. Harga rata rata koefisien perpindahan kalor total untuk alat penukar panas pipa ganda dengan tube menggunakan bahan Stainless Steel, sehingga jumlah kalor yang di transfer dari fluida yang berada di tube ke fluida yang berada di shell juga berbeda. dengan Penambahan sirip pada sisi tube dengan jumlah yang berbeda sehingga luas permukaan tube yang diuji berbeda inilah yang menyebabkan perolehan nilai penurunaan suhu memberikan hasil yang berbeda. Perolehan nilai penurunan suhu bahan tersebut mengalami peningkatan seiring dengan penambahan jumlah sirip dan kerapatan sirip yang terpasang. Jadi untuk penurunan suhu yang paling cepat turun dalam penelitian ini adalah tipe sirip 9 yaitu sebesar 45,3 0C.

Proses pengelasan telah berkembang pesat saat ini, baik untuk material logam maupun non logam. Salah satu material non logam yang disambung dengan proses pengelasan adalah plastik. Pada saat ini penggunaan produk berbahan material plastik semakin meningkat, maka untuk proses pengelasan material plastik menggunakan metode Hot-Gas Welding (HGW). Diketahui bahwa dalam proses pengelasan konduktifitas material sangat mempengaruhi kwalitas sambungan las, semakin tinggi konduktifitas maka kwalitas hasil pengelasan akan semakin baik. Di sisi lain diketahui bahwa material plastik memiliki tingkat konduktivitas yang rendah, maka dalam proses pengelasan plastik tersebut akan menjadi kendala. Tujuan dari penelitian ini adalah melakukan studi untuk meningkatkan kwalitas sambungan las material plastik yang dikhususkan pada material HDPE, yaitu mengetahui pengaruh temperatur pelat-landasan pada Jig Hot-Gas Welding dan sudut V-groove terhadap kekuatan tarik sambungan las HDPE sheet. Metode penelitian yang digunakan adalah eksperimental dengan variasi temperatur pelat landasan 30°C, 70°C, 110°C, dan 150°C, sedangkan variasi sudut V-groove yang digunakan 40°, 60°, dan 75°. Standar uji tarik mengunakan standar ASTM D 638-03, sebagai data penunjang dilakukan foto makrostruktur dari masing-masing sambungan las. Hasil penelitian ini diperoleh temperatur pelat landasan dan sudut V-groove berpengaruh tinggi terhadap kekuatan tarik lasan HDPE sheet selama proses hot-gas welding. Hasil interaksi antara variasi temperatur pelat landasan dan variasi sudut v-groove diperoleh bahwa pada temperatur pelat landasan 150°C dan sudut V-groove 60° didapatkan nilai maksimum kekuatan tarik lasan 18,8 MPa atau 87,5% terhadap kekuatan tarik material HDPE sheet tanpa sambungan.
