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.
The boat plays significant role in supporting the household business scale for the seaweed farmers. Their current boat are made from fiberglass reinforced plastic (FRP) which is lighter then the wooden boat. However, based on the field survey in the seaweed farmers boats in the area of Pattontongan village, Jeneponto regency, their boat is susceptible for sinking if any leak is occur on the boat body since they are not designed with the reserved buoyancy system. Geometry and the reserved buoyancy of their boat become the serious issues. Hence, an improved design for their boat is need to be developed with the criteria of the boat capacity and safety. This paper discusses two of the improved design of the boats which are ND1 (design 1) and ND2 (design 2). The result shows an improved design with the additional of the boat reserved buoyancy while considering the boat capacity. The parameter of the boat design is the relationship between the boat reserved buoyancy volume and the boat weight which is called anti sinking ratio. The anti sinking ratio for ND1 with the boat length 6 meters, width 0.85 meter, and height 0.5 meter is ≥ 1. The ratio is obtained in the condition of the boat reserved buoyancy of 0.066m3 and the boat carrying capacity of 0.969m3. Meanwhile, the anti sinking ratio for ND2 with the boat length of 4.2 meters, width 1 meter and height 0.5 meter is ≥ 1 in the condition of the boat reserved buoyancy of 0.055m3 and the boat carrying capacity of 0.936m3.
