IGSS ITERA Geotechnical and Seismic Suite
GEOTERA

Geotechnical Toolkit for Earth Retention & slope Analysis

Perancangan geoteknik yang bisa diaudit sel demi sel Geotechnical design you can audit cell by cell

Satu engine tervalidasi, dua wajah: GUI desktop untuk merancang cepat, dan workbook Excel teraudit untuk diserahkan, diperiksa, dan dilampirkan ke laporan. Berbasis SNI 8460:2017 dengan jalur kepatuhan seismik ASCE 7-10. One validated engine, two faces: a desktop GUI for designing quickly, and auditable Excel workbooks to hand over, review, and attach to reports. Built on SNI 8460:2017 with an ASCE 7-10 seismic compliance path.

PrinsipPrinciple

Dua wajah, satu mesinTwo faces, one engine

Excel dibangkitkan dari kode terujiExcel generated from tested code

Workbook tidak diketik manual — ia dibangkitkan oleh generator Python yang diuji. Hasilnya tetap Excel murni tanpa macro, sehingga siapa pun dapat membuka dan menelusuri rumusnya. Setiap halaman GUI wajib terdaftar sebagai punya workbook, atau diakui terbuka sebagai GUI-saja; penjaga uji menolak halaman baru yang tidak terdaftar. The workbooks are not hand-typed — they are generated by tested Python generators. The output stays pure, macro-free Excel, so anyone can open it and trace the formulas. Every GUI page must be registered as having a workbook, or openly acknowledged as GUI-only; a guard test rejects new pages that are not registered.

Tiap rumus bersitasiEvery formula cited

Nomor persamaan dan tabel dari SNI, Das, Kramer, dan FHWA menempel pada barisnya. Kriteria faktor keamanan statik dan seismik dipisah, dengan kolom sumber yang wajib diisi — tidak ada angka FK yang turun dari langit. Equation and table numbers from SNI, Das, Kramer, and FHWA sit on the rows they belong to. Static and seismic factor-of-safety criteria are kept separate, with a mandatory source column — no safety factor arrives from nowhere.

Faktor bergantung-chart adalah masukan, bukan tebakan Chart-dependent factors are input, not guesses

Nq*, α, K, δ, CRR, tmax dan sejenisnya harus diisi insinyur, dan nilainya ikut tercatat di lembar masukan sehingga dapat ditelusuri pemeriksa laporan. Nq*, α, K, δ, CRR, tmax and the like are supplied by the engineer, and each value is recorded on the input sheet so a reviewer can trace where it came from.

ValidasiValidation

Empat lapis pembuktianFour layers of proof

Tiap modul diuji berlapis: contoh soal terbitan, kasus batas fisis, pembanding perangkat lunak luar, dan rekalkulasi workbook terhadap engine. Each module is tested in layers: published worked examples, physical limit cases, an external software comparator, and workbook recalculation against the engine.

Benchmark ikut di dalam workbook The benchmark travels inside the workbook

Lembar 07_VALIDASI membawa contoh soal terbitan beserta galatnya di dalam berkas Excel, sehingga penerima dapat memeriksanya tanpa perangkat lunak tambahan. The 07_VALIDASI sheet carries the published worked example and its error inside the Excel file, so whoever receives it can check without any extra software.

Strip verifikasi di layarOn-screen verification strip

Tiap halaman GUI menampilkan tolok ukur yang sedang berlaku bagi modul itu di bagian atas layar — misalnya Das Ex. 15.8, GeoStudio M-P, dan LibreOffice — sehingga dasar angkanya terlihat saat merancang. Every GUI page shows the benchmarks currently backing that module along the top of the screen — Das Ex. 15.8, GeoStudio M-P, LibreOffice — so the basis of the numbers is visible while you design.

Filosofi desain.Design philosophy. Utama ASD (faktor keamanan tunggal), sesuai praktik Indonesia dan format SNI 8460. Kriteria LRFD (AASHTO/Eurocode) ditampilkan terpisah karena tidak boleh dicampur dengan hasil ASD. Primarily ASD (a single safety factor), matching Indonesian practice and the SNI 8460 format. LRFD criteria (AASHTO/Eurocode) are shown separately because they must not be mixed with ASD results.

Unduh GEOTERAGet GEOTERA

GEOTERA masih pra-rilis. Exe standalone dan seluruh workbook prototipe akan dilampirkan pada rilis publik pertama; halaman unduh memuat statusnya beserta checksum berkas yang sudah dibangun. GEOTERA is still pre-release. The standalone exe and all prototype workbooks will be attached to the first public release; the downloads page carries the current status together with the checksum of the build that exists today.
