Abstract

Sistem ballast pada kapal berguna untuk mengatur posisi kapal baik trim maupun oleng ataupun even keel. Untuk itu ballast ditempatkan didalam ceruk belakang, ceruk depan, tangki-tangki dasar ganda, tangki tegak dan tangki samping. Perencanaan tentang sistem ballast yang baik  harus memperhatikan faktor – faktor seperti beban yang ditanggung pipa dan temperatur kerja pada pipa secara garis besar perancangan sistem pipa ini tidak boleh menghasilkan tegangan yang lebih tinggi dari tegangan pipa yang diizinkan dan bisa diterima oleh jenis material pipa tersebut. Maka dari itu untuk mengurangi suatu tegangan pada pipa dapat digunakan penambahan support yang nantinya akan didesain menggunakan software CAESAR II dengan variasi pembebanan sustain load dan operation load

Abstract

The strength of international competitiveness encouraged a shipyard to reduce cost of materials and labor. Therefore, a shipyard did a measurement to improve the rationalization toward labor productivity. This study aimed to compare the path model from strategies of labor productivity and competitiveness of medium size shipyard in region of Batam and Java. The normality test of questionnaire data at 200 respondents who are competent in the feld of shipbuilding through the ratio of skewness and kurtosis did not show normal distribution from the data. Test of model feasibility through PLS algorithm and bootstrapping showed moderate criterion and no signifcant diference in the variable path for both regions. The frst latent variable: shipyard competitiveness is infuenced by the strategic policy and labor productivity, while the second latent variable: labor productivity is infuenced by work activity, strategic policy, and corporate culture. Test of model segmentation through FIMIX-PLS showed good criterion and osignifcant diference in the interaction of variable heterogeneity for both regions. The fnal result of shipyards PLS path modeling showed a consistent relationship between strategic policy and labor productivity in order to increase the Indonesian shipyard competitiveness.
