Foreword
We are pleased that EPI International Journal of Engineering (EPI-IJE) is presenting its 3rd issue. We are also excited that the numbers of authors’ country of origin who published their papers in this issue has also increased. The country variety of submission will help to promote the journal globally. We are also delighted that this issue contains a special topic on Composite Materials & Structures.
Besides the special issue on Composite Materials & Structures, this issue also contains 5 (five) other major topics which are Naval Architecture, Ocean, and Marine Engineering, Electrical and Informatics Engineering, Civil and Environmental Engineering, Mechanical and Industrial Engineering and Multi- disciplinary Engineering. The first paper in Composite Materials & Structures Engineering group conduct a study on manufacture of continuous Glass Fiber/Polylactic Acid (PLA) composite and its properties. Then the second paper in this group studies the shear behavior of concrete beams strengthened with CFRP Grid and PCM Shotcrete. The third paper discuss the characteristics of activated carbon from the utilization of Red Chili Trees. The fourth paper studies the multi-objective optimization of variable-stiffness composites fabricated by tailored fiber placement machine. The last paper in this group studies the effect of using different elastic moduli on vibration of laminated CFRP rectangular plates. The group of Naval Architecture, Ocean, and Marine System Engineering contains 3 (three) papers. The first paper discusses the heave and pitch motion performances of a ship towing system incorporated with symmetrical bridle towline model. The second paper discusses the heave and pitch motions of a towed ship in waves incorporated with an asymmetrical bridle towline model. The last paper studies the influences of lengthening dimension of ro-ro ferry toward the considerations of hydrodynamics characteristic and loading capacity aspect.
In the next group which is Electrical and Informatics Engineering group, 2 (two) papers are published. The first paper studies the autonomy stemmer algorithm for legal and illegal affix detection use finite-state automata method. The second paper in this group studies the characteristic of current diffusion on double- plate conductor for smaller resistive load. The group of Civil and Environmental Engineering contains only one paper which conducts the experimental study of the use of pumice sand in the rigid pavement. The group of Mechanical and Industrial Engineering contains 3 (three) papers. The first paper in this group studies the free vibration analysis of L-shaped folded thin plates. The second paper developed a mathematical modeling in combining photovoltaic and thermoelectric generator using a spectrum splitter. The last paper investigates the harmonic response of strut fin on a planar motion mechanism. The last group contains one paper, which conducts a study on renewable energy developments in Indonesia; opportunities for improving local production energy for local consumption.
As the guest editor of this edition, I am greatly grateful to all authors for their outstanding papers and remarkable work. We hope these high-quality papers would give a contribution to knowledge development of their respective field of study. I also would like to express my gratitude to JICA C-BEST Project team, reviewers, editors, and all other people who have contributed to the publishing of this issue.
Warm regards,
Dr. Eng. A. Arwin Amiruddin Editor-in-Chief of EPI-IJE
