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 field 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 significant difference in the variable path for both regions. The first latent variable: shipyard competitiveness is influenced by the strategic policy and labor productivity, while the second latent variable: labor productivity is influenced by work activity, strategic policy, and corporate culture. Test of model segmentation through FIMIX-PLS showed good criterion and no significant difference in the interaction of variable heterogeneity for both regions. The final result of shipyards PLS path modeling showed a consistent relationship between strategic policy and labor productivity in order to increase the Indonesian shipyard competitiveness.

Abstract

Sandwich panel sebagai material komposit memerlukan metode pembuatan yang khusus, untuk menghasilkan kondisi fisik material yang terbaik. Studi ini menyampaikan proses pembuatan sandwich panel untuk keperluan pengujian kekuatan material. Sandwich panel dibentuk dengan metode cetak untuk mempermudah proses pekerjaan dan dapat diulangi jika terjadi kegagalan. Beberapa kegagalan terjadi dalam proses pembuatan hingga proses preparasi spesimen yang dipengaruhi oleh beberapa hal, seperti keretakan akibat temperatur sinar matahari, perbedaan kerekatan antar lapisan dari kondisi faceplate (halus dan kasar), serta metode pemotongan sandwich panel yang membutuhkan metode pemotongan pada temperatur rendah dan tidak menghasilkan getaran yang tinggi untuk menghindari kerusakan pada material sebelum dilakukannya pengujian kekuatan material.
