Abstract: | Galangan kapal rakyat UD Wahyu Asih Fiberglass sudah banyak
memproduksi kapal FRP. Namun, pembuatan kapal tersebut tidak mengikuti
ketentuan yang ditetapkan oleh Biro Klasifikasi Indonesia (BKI) dan hanya
berdasarkan pengetahuan otodidak dari pemilik usaha. Selain itu, galangan kapal
ini belum dapat membuktikan kekuatan konstruksi lambung kapal FRP yang
dibuatnya secara ilmiah. Tujuan penelitian ini adalah untuk mendeskripsikan
proses pembuatan konstruksi kapal dan material yang digunakan serta
mendapatkan nilai kekuatan uji tarik, uji tekan, dan modulus elastisitas untuk
konstruksi lambung kapal FRP. Data dikumpulkan dengan studi literatur,
observasi lapang, pembuatan spesimen, serta pengujian kekuatan konstruksi (uji
tarik, uji tekan, dan modulus elastisitas), dilanjutkan dengan analisis deskriptif
komparatif. Hasil penelitian menunjukkan bahwa material yang digunakan dalam
membuat kapal FRP meliputi resin yukalac 235, gelcoat yukalac g-123 t-ex,
CSM300, WR600, WR800, katalis mepoxe, cobalt napthanate, pyrogenic silica,
talc, pewarna matapel unipol, miracle gloss, minyak tanah, ivory rubbing
compound, dan kit (compound). Adapun proses pembuatan kapal FRP meliputi
proses pembuatan laminasi dan proses finishing dengan menggunakan metode
hand lay up. Meskipun kekuatan tarik sudah memenuhi nilai minimum yang
ditetapkan oleh BKI, namun kekuatan tekan dan modulus elastisitas belum
memenuhi nilai minimum yang ditetapkan oleh BKI. Small shipyards UD Wahyu Asih Fiberglass have produced many FRP boats. However, the construction of these boats doesn't follow the regulations set by the Indonesian Classification Bureau (BKI) and is only based on the owner's self-taught knowledge. Additionally, these shipyards haven't been able to scientifically prove the structural strength of their FRP boat hulls. The aim of this research is to describe the process of constructing a boat and the materials used as well as to obtain the values of tensile strength, compressive strength, and modulus of elasticity for FRP boat hull construction. Data was collected through literature studies, field observations, specimen making, and construction strength testing (tensile test, compressive test, and modulus of elasticity), followed by descriptive comparative analysis. The materials used in making FRP boats include yukalac 235 resin, yukalac g-123 t-ex gelcoat, CSM300, WR600, WR800, mepoxe catalyst, cobalt napthanate, pyrogenic silica, talc, matapel unipol dye, miracle gloss, kerosene, ivory rubbing compound, and kit (compound). The process of making FRP boats includes the laminated structures and finishing processes using the hand lay-up method. Although the tensile strength meets the minimum values set by BKI, the compressive strength and elastic modulus don't yet meet the minimum values set by BKI. |
