Intisari: Pada kondisi operasionalnya, tempat sampah outdoor menderita beberapa beban mekanik seperti berat dari sampah, beban benturan saat pengosongan maupun beban reaksi kimia dan radiasi matahari. Dari kondisi-kondisi tersebut, penting untuk dipilih material yang tepat, oleh karena itu, komposit polimer diperkuat serat kaca digunakan. Dibandingkan dengan produk-produk termoplastic, komposit polimer diperkuat serat kaca lebih ideal dari segi ketahanan mekanik atau pun lingkungan, kemudian, kemudahan dan tidak dibutuhkanya peralatan produksi yang mahal memungkinkan produsen lokal memproduksinya. Sayangnya, proses produksinya relatif lambat, dengan pemborosan waktu terbanyak pada proses pengeringanya, yang memerlukan waktu 81 menit, atau sekitar 51.6% waktu proses totalnya, sehingga metode pengeringan baru harus diertimbangkan. Dengan bantuan radiasi inframerah, proses pengeringan gelcoat berkurang dari 47 ke 7 menit, dan untuk resin matrix berkurang dari 69.5 menjadi 11 menit.

Kata Kunci: Komposit polimer diperkuat serat kaca, radiasi inframerah, tempat sampah fiberglass outdoor.

Abstract : In its operational conditions, outdoor trash bins suffering some mechanical loads such as the weight of the trash, impact load for trash emptying as well as chemical and sunlight radiation loads. From these conditions it is important to consider right material, hence, fiberglass reinforced polymer composite used. Compared to thermoplastic products, fiberglass-reinforced polymer composite is more ideal in term of its mechanical as well as its environmental durability, then, the simple and no need of expensive tools allows local manufacturer to produce it. Unfortunately, it is slower on its production rate, with the most time-consuming step is the curing process, which takes place 81 minutes or about 51.6% of the whole process, hence new method of curing must be taking into account. With the aid of infrared radiation, the curing process time of gelcoat reduced from 47 to 7 minutes, and for the matrix resin reduced from 69.5 to 11 minutes.
