Abstract

Sebaran hasil analisis geokimia untuk logam dasar baik contoh-contoh pantai maupun lepas pantai memperlihatkan adanya pengelompokan kandungan baik untuk unsur-unsur Tembaga (Cu), Timbal (Pb), dan seng (Zn) ataupun logam emas (Au) dan perak (Ag). Perbedaan lingkungan pengendapan di pantai dan lepas pantai berpengaruh kepada kandungan logam dasar. Di lingkungan pantai kandungan unsur logam dasar yaitu Cu, Pb dan Zn rata-rata lebih tinggi dari pada lingkungan pengendapan lepas pantai. Kandungan emas (Au) dan perak (Ag) dipantai juga lebih tinggi di bandingkan dengan di lepas pantai. Sebaran logam dasar dari timur ke barat memperlihatkan variasi kandungan yang juga berbeda antara logam dasar P, Cu dan kandungan Zn. Kandungan Zn selalu lebih tinggi daripada kandungan Pb dan Cu. Variasi ini juga terlihat berbeda antara lingkungan pantai dengan variasi yang jauh lebih mencolok/variatif pada lingkungan lepas pantai.

Abstract

Pemadatan tanah merupakan salah satu pekerjaan penting dalam setiap proyek perkerasan jalan. Pemadatan tanah berfungsi untuk meningkatkan kekuatan tanah yang memberikan daya dukung kepada lapisan jalan di atasnya, serta juga berfungsi untuk mengurangin besar penurunan tanah yang tidak diinginkan. Dalam setiap pemadatan tanah diperlukan kadar air optimum untuk mencapai kepadatan maksimum yang dapat diketahui dengan uji proctor . Uji proctor yang masih manual dalam pemberian bebannya mengakibatkan membutuhkan tenaga manusia yang cukup besar dalam penggunaannya. Pada penelitian ini membandingkan uji proctor modified dengan pemodelan alat tekan pemadat modifikasi dengan menggunakan tekanan kontak alat berat pemadat tanah dalam usaha mengantikan uji proctor manual dengan alat modifikasi yang lebih praktis. Tanah yang digunakan adalah tanah timbunan pilihan, berasal dari Desa Gedung Agung, Kecamatan Jati Agung, Lampung Selatan.
