Skripsi, Surakarta : Fakultas Keguruan dan Ilmu Pendidikan Universitas Sebelas Maret, Februari 2017. Tujuan dari penelitian ini untuk (1) mengetahui apakah berat jenis beton yang dihasilkan masuk kategori berat jenis beton normal; (2) mengetahui pengaruh serat ijuk dan serat sabut kelapa terhadap kuat tekan beton; (3) mengetahui pengaruh serat ijuk dan serat sabut kelapa terhadap kuat lentur beton; (4) mengetahui nilai kuat tekan dan kuat lentur maksimal yang dihasilkan dari persentase penambahan serat ijuk dan serat sabut kelapa. Penelitian menggunakan metode kuantitatif eksperimen dan teknik analisa data menggunakan regresi. Variabel yang mempengaruhi dalam penelitian ini adalah (1) Variabel bebas: variasi penambahan serat ijuk dan serat sabut kelapa yaitu 0,00%; 0,50%; 1,00%; 1,50%; 2,00% dan 2,50%, (2) Variabel terikat: kuat tekan dan kuat lentur beton akibat penambahan variasi serat ijuk dan serat sabut kelapa. Hasil penelitian sebagai berikut, Pertama, Hasil pengujian berat jenis pada persentase penambahan serat ijuk dan serat sabut kelapa 0,00%, 0,50%, 1,00%, 1,50%, 2,00% dan 2,50%, termasuk dalam beton normal karena memenuhi syarat berat jenis beton normal menurut SNI 03-2847-2002 yaitu sebesar 2200 – 2500 kg/m3. Kedua, hasil pengujian kuat tekan beton menunjukkan bahwa penambahan serat ijuk dan serat sabut kelapa berpengaruh sedang bersifat negatif terhadap kuat tekan beton. Ketiga, hasil pengujian kuat lentur beton menunjukkan bahwa penambahan serat ijuk dan serat sabut kelapa berpengaruh sedang bersifat positif terhadap kuat lentur beton. Keempat, hasil kuat tekan beton dengan penambahan serat ijuk dan serat sabut kelapa terdapat nilai maksimal pada persentase 0,50% dengan nilai kuat tekan sebesar 27,11 MPa. Sedangkan penambahan serat ijuk dan serat sabut kelapa memiliki nilai kuat lentur maksimal pada persentase 3,415% dengan nilai kuat lentur sebesar 4,117 MPa.

THE INFLUENCE OF PALM FIBER AND COCONUT COIR ADDITION ON COMPRESSIVE STRENGTH AND FLEXURAL STRENGTH AS TEACHING MATERIALS FOR CONCRETE TECHNOLOGY COURSE. Thesis, Surakarta: Teacher Training and Education Faculty of the Sebelas Maret University, February 2017. The purpose of this research were to (1) determine whether the density of concrete that was produced in this research included into normal weight concrete category; (2) determine the influence of palm fiber and coconut coir on compressive strength of concrete; (3) determine the influence of palm fiber and coconut coir on flexural strength of concrete; (4) determine the maximum value of compressive strength and flexural strength that was produced from percentage of palm fiber and coconut coir addition. The research used quantitative method while technique of data analysis was regression. Variables in this research were (1) the independent variables: variations addition of palm fiber and coconut coir were 0,00%; 0,50%; 1,00%; 1,50%; 2,00% and 2,50%, (2) the dependent variable: the compressive strength and flexural strength of concreteas the effect of variation of palm fiber and coconut coir addition. The results of this research were: First, the specific gravity test results on the percentage of palm fiber and coconut coir 0,00%; 0,50%; 1,00%; 1,50%; 2,00% and 2,50%, included into normal concrete because it qualify as the density of normal concrete according to SNI 03-2847-2002 which amounted 2200 - 2500 kg/m3. Second, the compressive strength of concrete test result showed that the addition of palm fiber and coconut coir was being a negative influence on the compressive strength of concrete. Third, the flexural strength of concrete test result showed that the addition of palm fiber and coconut coir was strong and being positive effect on the flexural strength of concrete. Fourth, the compressive strength of concrete with the addition of palm fiber and coconut coir, there were an maximal value on the percentage of 0,50% with the highest compressive strength value was 27,11 MPa. While the influence of the addition of palm fiberand coconut coir had an maximal flexural strength value on the percentage of 3,415% with the value of flexural strength was 4,117 MPa. Keywords: compressive strength, flexural strength, concrete fiber
