Abstract
Permasalahan pantai di Indonesia yang belum terlindungi oleh struktur pelindung pantai jumlahnya mencapai 136 di tahun 2018 – 2021. Di sisi lain, perencanaan analisis perhitungan armour unit sebagai pelapis lindung struktur pelindung pantai membutuhkan proses dan perhitungan yang panjang. Oleh alasan tersebut, dibuatlah sebuah perangkat lunak perhitungan armour unit jenis Hexaloc yang disebut Hexaloc Calculator menggunakan Virtual Basic Application Excel. Perangkat lunak yang dibuat akan melalui uji benchmarking dan Uji-T Dependen secara statistik dengan Online Xbloc Calculator yang dibuat oleh Delta Marine Consultants. Formula perhitungan akan menggunakan Formula Hudson dengan batasan masalah hanya menggunakan tiga ukuran slope, yaitu 1:2, 2:3, dan 3:4. Perangkat lunak Hexaloc Calculator selanjutnya digunakan untuk menghitung perencanaan awal berat armour unit Hexaloc untuk studi kasus Batang dengan dua arah dominan gelombang, yaitu North West dan East South East. Kala ulang yang digunakan adalah 50 tahun. Hasil dari perhitungan Hexaloc Calculator menunjukkan bahwa semakin kecil nilai cot θ, maka akan semakin besar berat armour unit Hexaloc yang dibutuhkan untuk menahan gelombang. Dari hasil analisi juga diketahui bahwa berat armour unit Hexaloc pada section head lebih besar daripada section trunk.

The issue of unprotected coastlines in Indonesia amounted to 136 locations between 2018 and 2021. On the other hand, the planning and analysis for calculating armor units as protective layers for coastal defense structures entail extensive and intricate processes. To address this challenge, the Hexaloc Calculator, a software tool developed using Visual Basic Application Excel, was created. This software undergoes benchmarking and statistical Dependent T-tests against the Online Xbloc Calculator developed by Delta Marine Consultants. The calculation formula is based on the Hudson Formula, considering limitations such as three slope dimensions: 1:2, 2:3, and 3:4. The Hexaloc Calculator software is then employed to compute preliminary plans for the weight of Hexaloc armor units in the Batang case study, considering two dominant wave directions—North West and East South East— over a 50-year recurrence interval. The outcomes from the Hexaloc Calculator computations reveal that as the cot θ value decreases, the required weight of Hexaloc armor units to withstand waves increases. Additionally, the analysis indicates that the weight of Hexaloc armor units in the section head surpasses that of the section trunk.
