Traditional wooden fishing boats are still being produced by most of the traditional wooden shipyards in Indonesia specifically in the area of South Sulawesi. Nevertheless, the traditional wooden boat craftsman facing the difficulty of wooden log supply as the main wooden boat material especially for wooden frame construction despite the increasing demand for wooden material for the boat construction. The difficulty to acquire the specific wooden for wooden frame caused by the specific requirements of each wooden frame. They must be in the specific shape according to the specific curvature of each transversal boat section along the boat length. Hence, for the sustainability of wooden boat construction process, alternative material is needed for replacing the certain wooden boat construction component, especially for wooden frames. Fortunately, research relating to the use of alternative material for wooden boat construction have been conducted. The focus of the research is on the use of steel frame to replace the wooden frame on the wooden boat construction. This paper discusses the cost comparison for the fabrication and installation process as well as the material cost of the steel frame to the wooden boat construction with wooden frame to the wooden boat construction. The result shows that the cost for fabricating and installing steel frame is 13% higher to compare to the wooden frame. However, if the total wooden boat construction cost is being considered, the total difference is only 3%.
Masyarakat pesisir Jeneponto melakukan usaha budidaya rumput laut secara berkelompok maupun perseorangan. Salah satu kelompok pebudidaya rumput laut di Lingkungan Pattontongan Kecamatan Binamu yaitu Kelompok Pattotongan City. Sarana produksi yang digunakan dalam budidaya rumput laut antara lain perahu. Umumnya perahu fiberglass masih didapatkan dari bantuan atau hibah pemerintah, jarang sekali yang membeli langsung karena terkendala biaya. Sehingga perlu ada upaya untuk dapat menekan biaya perolehan perahu yaitu pebudidaya membuat sendiri perahu.
Pada bulan September dan Oktober tahun 2016, melalui program Ipteks Bagi Masyarakat (IBM) Universitas Hasanuddin dilakukan bimbingan dan pelatihan reparasi perahu fiberglass kepada kelompok pembudidaya dengan hasil budidaya mampu mengenal bahan dan peralatan reparasi fiberglass dan teknik-teknik mereparasi lambung perahu. Kemampuan ini belum cukup untuk dapat membuat perahu, maka diperlukan sebuah kegiatan berupa pengayaan keterampilan dalam pembuatan perahu.
Hasil yang diperoleh melalui pengayaan keterampilan ini adalah peserta mampu (1) membaca gambar desain perahu. (2) memidahkan desain perahu ke skala penuh (3) membuat cetakan perahu (4) melaminasi perahu atau mampu menerapkan metode hand lay-up dengan baik dan tepat.
Manfaat yang dapat diperoleh dengan keterampilan yang dimiliki peserta adalah mampu membuat sendiri perahu sehingga dapat menghemat biaya modal. Lebih dari itu, dapat membuka lapangan kerja yang bermuara pada peningkatan kesejahteraan pebudidaya.
As its main material, specific timbers for supporting boat structure are required in the construction of traditional wooden fishing boat in Indonesia. The requirements for the specific timbers are vary such as it must be water resistant for ship skin planking and must be in the specific form for the boat frames in which the curvature will be different according to the specific curvature of each transversal boat section along the boat length. Currently, the required specific form of timbers for the boat frames are becoming difficult to be acquired especially in the midship area of the ship which requires extreme curvature. The difficulty to acquire the specific curvature form of frames as required have threaten the sustainability of wooden boat construction process in Indonesia. Hence, an alternative material for replacing the wooden material for boat frames is needed. The requirements for the alternative material are as follows; it must be easy to be formed according to the boat transversal section form along the boat length and must be strong enough to support the strength of the wooden boat hull. This research is conducted in order to analyse the feasibility of steel frame application for replacing wooden frame in the construction of traditional wooden fishing boat. Some alternatives of different steel frame dimensions with specific profile forms are analysed to determine the appropriate steel frame construction for certain type of wooden fishing boat. In the end, a recommendation of the steel frame dimensions for replacing wooden frame on a certain traditional wooden fishing boat is proposed.
