Untuk meningkatkan nilai stabilitas diperlukan bahan tambah lain yang memiliki potensi seperti limbah Abu Cangkang Tiram (OSA) dan limbah <em>High Density Polyethylene </em>(HDPE). OSA mempunyai sifat kimia yang mengandung kapur dan silika yang berfungsi untuk keawetan dan mengunci antar agregat pada perkerasan jalan. Sedangkan HDPE memiliki kekuatan yang tinggi dan kaku serta perilaku untuk mengikat sehingga dapat memperkuat ikatan antara agregat dan OSA dan menambah perkuatan terhadap campuran aspal porus. Tujuan penelitian ini adalah untuk menentukan Kadar Aspal Optimum (OAC) pada campuran aspal porus, dan menganalisis variasi persentase terbaik OSA dan limbah HDPE sebagai substitusi aspal pen 60/70. Pengujian yang dilakukan adalah pemeriksaan terhadap parameter <em>Marshall</em>.

OSA contains of chemical characteristics consisting of calcium and silica for durability and locking the aggregate and road pavement. While HDPE is rigid, high strength, and binder that it can strengthen the bond of aggregate and OSA as well as strengthen porous asphalt mix. The research aims to determine OAC to porous asphalt mix, and analyze the best percentage variation of OSA filler substitution and HDPE waste as asphalt pen 60/70 substitution.

Penyusunan Peta Kategori Desain Seismik (KDS) Indonesia saat ini masih terkendala karena keterbatasan data penyelidikan tanah. Meskipun demikian, problem tersebut dapat diatasi dengan melakukan pendekatan berdasarkan data kecepatan gelombang geser pada kedalaman 30 (Vs30) yang disediakan oleh (USGS, 2020). Tujuan dari penelitian ini adalah melakukan penyusunan Peta Kategori Desain Seismik untuk Provinsi Daerah Istimewa Yogyakarta (DIY). Tahapan penelitian diawali dengan pengumpulan data, perhitungan percepatan tanah dan penentuan kategori desain seismik untuk setiap titik dari 3759 titik tinjauan. Hasil penyusunan peta kategori desain seismik Daerah Istimewa Yogyakarta pada kategori risiko I, II, dan III menunjukkan hasil Kabupaten Bantul, Kota Yogyakarta masuk dalam kategori risiko tinggi (KDS D), sedangkan Kabupaten Sleman, Kabupaten Kulonprogo, dan Kabupaten Gunung Kidul masuk dalam kategori risiko sedang hingga tinggi (B, C, dan D).
