Abstract

This study aims to evaluate the use of lime as an alternative binder to replace cement in mortar mixtures, with the addition of crushed brick powder to enhance mechanical strength. This approach offers an environmentally friendly solution to the high carbon emissions associated with cement production. The mortar mixture was prepared using a ratio of 1:1:3 (lime : crushed brick powder : sand) with a water-to-binder ratio of 0.5. Tests were conducted to assess the compressive strength and density of the mortar at 7, 14, and 28 days of curing. The results showed that the average compressive strength increased with curing time, reaching 1.49 MPa at 7 days, 1.86 MPa at 14 days, and 2.40 MPa at 28 days. The mortar density ranged from 2,080 to 2,680 kg/m³, with average values of 2,513 kg/m³ (7 days), 2,342 kg/m³ (14 days), and 2,230 kg/m³ (28 days). These findings indicate that the combination of lime and crushed brick powder improves mortar performance and has the potential to be a more sustainable alternative construction material. Keywords: Mortar, Lime, Crushed brick powder, Compressive strength, Density

Abstract

Universitas Nusa Nipa bekerja sama dengan Kamar Dagang dan Industri (KADIN) Kabupaten Sikka dalam pengembangan kerajinan tangan dan cendramata sejak tahun 2015. Asosiasi Pelaku UMKM Kabupaten Sikka (AKUSIKKA) dibentuk di bawah pengawasan KADIN Kabupaten Sikka sebagai lembaga yang bergerak dalam seni kerajinan tangan dan cendramata. Mereka memproduksi berbagai souvenir seperti topi, dompet, sarung, selendang, asesoris tenun, camilan, dan produk khas Flores. Produksi dilakukan oleh beberapa pengrajin skala kecil yang tergabung dalam lembaga ini. Galeri AKUSIKKA di Kecamatan Alok, Kota Maumere, merupakan pusat penjualan berbagai kerajinan tangan, seperti tenun ikat, selendang, gelang, dompet, tas, topi, dan kain tenun sarung. Namun, AKUSIKKA menghadapi keterbatasan dalam akses informasi dan pemasaran. Oleh karena itu, perlu dikembangkan strategi e-Commerce untuk pemasaran produk UMKM mereka. Solusi yang diusulkan adalah aplikasi B'Pung Lapak, yang memungkinkan transaksi antara penjual dan pembeli, distribusi barang, dan komunikasi antar anggota komunitas. Aplikasi ini juga akan menyediakan informasi produk, layanan pembayaran, dan bantuan konsumen. Tujuannya adalah untuk meningkatkan pemasaran produk UMKM AKUSIKKA dalam seni kerajinan tangan dan cendramata.
