Abstract

Kota Melaka, ibu kota Melaka, Malaysia, merupakan Situs Warisan Dunia UNESCO dan pusat sejarah yang dibentuk oleh pengaruh Portugis, Belanda, dan Inggris. Terkenal dengan landmark seperti A Famosa dan Gereja Santo Paulus.  Kota ini menampilkan warisan budaya yang kaya dan kuliner unik yang memadukan cita rasa Melayu, Cina, India, dan Portugis. Melaka berlokasi strategis di sepanjang Selat Malaka. Kota Melaka berkembang pesat di bidang pariwisata, perdagangan, dan jasa dengan infrastruktur modern. Kota ini juga memprioritaskan pelestarian lingkungan seperti pendirian Pusat Konservasi dan Informasi Penyu (PKPP), yang berfokus pada perlindungan penyu sisik dan penyu hijau melalui pelestarian habitat, edukasi, dan penelitian. Meskipun ada tantangan seperti perburuan liar dan perubahan iklim, upaya kolaboratif antara pemerintah, LSM, dan masyarakat memastikan perlindungan keanekaragaman hayati laut. Melaka menyeimbangkan antara pelestarian warisan budaya, pertumbuhan ekonomi, dan kelestarian lingkungan.

Abstract

Palm Crude Oil (CPO) production generates substantial waste, including Spent Bleaching Earth (SBE), which is difficult to recycle. This research explores the stabilization of SBE using seashells for use in concrete mixtures. The goal is to enhance concrete’s durability by utilizing the calcium content in stabilized SBE. In this study, we tested concrete with a design strength of 30 MPa. The tests included compressive strength on 150x300 mm cylinders, flexural strength on 600x150x150 mm beams after 28 days of curing, and water blasting resistance using two methods. The water blasting test assessed the concrete’s resistance to water pressure on 500 x 350 x 50 mm samples over three consecutive days. The results showed that concrete with a 7.5% SBE variation achieved a compressive strength of 42.06 MPa, higher than the design strength. Flexural strength increased by 4.67% with a 10% variation in SBE. However, the water blasting tests revealed that both concrete variations exhibited greater damage than normal concrete, indicating that while SBE improves compressive and flexural strength, it may reduce the concrete’s water resistance.
