Abstract

ABSTRAK Limbah atau sampah merupakan suatu bahan yang terbuang atau dibuang dari sumber hasil aktivitas manusia maupun proses alam yang tidak memiliki nilai ekonomis. Pada dasarnya limbah-limbah dari alam seperti cangkang biji karet dan sabut kelapa merupakan limbah yang dapat dimanfaatkan untuk bidang kontruksi salah satunya bisa dimanfaatkan dalam pencampuran beton sebagai material pengganti agregat kasar dan daya serat tambahan. Oleh karena itu, perlu adanya inovasi dalam memanfaatkan limbah tersebut agar mengurangi ketergantungan pemakaian agregat alami yang didapatkan dari sumber daya alam terbatas. Penelitian dilakukan di Laboratorium Struktur ,Teknik Sipil Universitas Islam Kalimantan Muhammad Arsyad Al Banjari, ,Kalimantan Selatan. Metode penilitian dilakuakan secara eksperimental. Hasil kuat tekan karakteristik untuk beton dengan 0% cangkang biji karet dan 0% sabut kelapa didapat sebesar K-268,186 kg/cm2, beton dengan 3% cangkang biji karet dan 0,5% sabut kelapa panjang 6 cm didapat sebesar K-102,688 kg/cm2, beton 6% cangkang biji karet dan 0,5% sabut kelapa panjang 9 cm didapat sebesar K-86,319 kg/cm2. Dari variasi diatas didapatkan perbandingan kuat tekan beton 3%, 6% cangkang biji karet dan bahan tambah 0,5% sabut kelapa dengan panjang 6, 9 cm tidak mencapai mutu K-250 kg/cm2. Beton mutu K-102,688 kg/cm2, masuk dalam kategori mutu beton kelas I non-struktural dan beton mutu K-86,319 kg/cm2, tidak masuk dalam kategori beton non-struktural maupun struktural. Kata Kunci : Cangkang Biji Karet, Sabut Kelapa, Agregat kasar, Material ABSTRACT Waste or garbage is a material that is wasted or discarded from the source of human activities or natural processes that have no economic value. Basically, wastes from nature such as rubber seed shells and coconut fiber are wastes that can be used for the construction sector, one of which can be used in mixing concrete as a substitute material for coarse aggregate and additional fiber power. Therefore, there is a need for innovation in utilizing this waste to reduce dependence on the use of natural aggregates obtained from limited natural resources. The research was conducted at the Civil Engineering Structure Laboratory, Islamic University of Kalimantan, Muhammad Arsyad Al Banjari, South Kalimantan. The research method is carried out experimentally. The results of characteristic compressive strength for concrete with 0% rubber seed shells and 0% coconut fiber were obtained at K-268.186 kg/cm2, concrete with 3% rubber seed shells and 0.5% coconut fiber 6 cm long was obtained at K-102.688 kg/cm2, concrete with 6% rubber seed shells and 0.5% coconut fiber 9 cm long was obtained at K-86.319 kg/cm2. From the variations above, a comparison of 3% concrete compressive strength, 6% rubber seed shells and 0.5% coconut fiber additives with a length of 6.9 cm does not reach the quality of K-250 kg/cm2. K-102,688 kg/cm2 quality concrete, included in the non-structural class I concrete quality category and K-86,319 kg/cm2 quality concrete, not included in the category of non-structural or structural concrete. Keywords: Rubber Seed Shells, Coconut fiber, Coarse Aggregate, Material
