Abstract
Semakin mahal dan langkanya bahan kayu sebagai material utama kapal ikan telah
mendorong para praktisi untuk meneliti bahan alternatif pengganti kayu. Bambu laminasi
memiliki sifat mekanis yang lebih besar daripada kayu jati, sehingga dinilai mampu
menggantikan kayu jati sebagai bahan utama kapal ikan. Namun masih ada keraguan jika
material ini digunakan pada kapal dengan kapasitas yang besar. Sehingga muncul pertanyaan
sampai ukuran berapakah kapal dengan bahan utama bambu laminasi mampu dibangun
berdasarkan aspek kekuatan dan ekonomis. Perhitungan diawali dengan menentukan ukuran
utama kapal yang dilanjutkan dengan menghitung ukuran komponen konstruksi kapal
berdasarkan BKI tahun 2013. Analisis kekuatan dilakukan dengan pemodelan kapal 3D
menggunakan pendekatan Finite Element Method (FEM). Sedangkan analisis ekonomis
dilakukan dengan membandingkan kapal berbahan bambu laminasi ori dan betung, dengan
kapal berbahan kayu jati. Hasil dari perhitungan dan analisis kekuatan menunjukkan bahwa
kapal dengan kapasitas 20 sampai 60 GT berbahan bambu laminasi memenuhi kriteria
kekuatan, yakni tidak melebihi tegangan yang diizinkan sebesar 142 Mpa untuk bambu
laminasi ori dan 120 Mpa untuk bambu laminasi betung. Hasil perhitungan dan analisis
ekonomis menunjukkan bahwa kapal berbahan bambu laminasi memiliki biaya produksi lebih
rendah daripada kapal kayu jati. Selisih biaya produksi paling rendah terdapat pada kapal 20
GT sebesar Rp 178.191.571,00; dan semakin besar kapasitas kapal maka selisih biaya
produksi menjadi semakin besar. Kapal berkapasitas 60 GT memilki selisih paling besar,
yakni Rp 383.428.715,00. Berdasarkan kondisi aktual dimana kapal kayu paling besar yang
umumnya dibangun hanya sampai kapasitas 60 GT, maka perhitungan dan analisis
dicukupkan pada kapasitas 60 GT.

The increase of expensiveness and scarcity wood as the main material of fishing boats
has encouraged practitioners to examine alternative wood materials. Bamboo laminate has
mechanical properties greater than teak, so it is considered capable of replacing the teak wood
as the main material of fishing boat. But there are still doubts if this material is used on ships
with large capacity. So the question arises as to what is the maximum size of the vessel with
the main material of bamboo laminate can be built based on the strength and economical
aspects. The calculation begins by determining the main dimension of boats, followed by
calculating the size of the components of the boat's construction by BKI 2013 edition.
Strength analysis is done by 3D vessel modeling approach using Finite Element Method
(FEM). While the economic analysis conducted by comparing boats made from bamboo
laminate ori and betung, with boats made from teak wood. The results of the calculation and
analysis indicates that the strength of boat with a capacity of 20 to 60 GT made from bamboo
laminate meets the criteria of strength, which does not exceed a permissable stress of 142
MPa for bamboo laminate ori and 120 MPa for bamboo laminate betung. The results of
calculation and economic analysis indicates that the boats made from bamboo laminate has
lower production costs than teak boat. The lowest difference in production cost is in 20 GT
vessels IDR 178,191,571.00; and as bigger as boat capacities the production cost difference
becomes larger. Boat with a capacity of 60 GT have the biggest difference, at IDR
383,428,715.00. Based on the actual conditions in which most large wooden boats that were
built only up to a capacity of 60 GT, the calculation and analysis on the capacity been
deffered at 60 GT.
