Beton merupakan salah satu bahan yang sering digunakan untuk pembangunan struktur bangunan, jembatan dan lain-lain. Beton terdiri dari campuran agregat halus (pasir), agregat kasar (kerikil), air, dan semen. Selain bahan tersebut, beton biasanya juga dicampur dengan bahan tambahan. Dalam penelitian ini digunakan serat batang pisang batu sebagai bahan tambahan dalam campuran beton.Penelitian ini bertujuan untuk mengetahui komposisi campuran serat batang pisang dalam beton, serta mengetahui perilaku keretakan beton saat dilakukan pengujian setelah adanya tambahan serat batang pisang pada campuran beton.Metode yang digunakan adalah metode eksperimental dengan variasi serat batang pohon pisang, yaitu 0% (beton normal); 2,5% dan 5%. Serat pisang dari batang pohon dikeringkan dan dipotong dengan panjang 5 cm dan ketebalan 3 mm. Dalam pengujian ini digunakan dua model benda uji, yaitu benda uji silinder berukuran 15x30 cm dan model pelat berukuran 100x100x10 cm. Pengujian yang dilakukan adalah kuat tekan beton yang dilakukan setelah beton mencapai umur 14 dan 28 hari dan pengujian susut yang dapat dilihat secara visual. Dari hasil pengujian secara visual dapat dilihat bahwa benda uji 3 yaitu beton dengan kandungan pisang 5% memiliki retak yang sangat halus dibandingkan dengan benda uji 2 (2,5%) dan dan benda uji 1 (0%). Untuk pengujian kuat tekan, benda uji 3 memberikan nilai 105 Mpa, benda uji 2 164 Mpa dan Benda uji 1 320 Mpa. Hasil kuat tekan berbanding terbalik dengan kemampuan menahan retak. Maka dapat disimpulkan bahwa penambahan serat pisang mengurangi kuat tekan beton namun menambah kemampuan beton menahan keretakan yang terjadi. Kata Kunci : Beton, Kuat Tekan, Serat Pisang   ABSTRACT Concrete was one of material which often used in building construction, bridge and others.

Renewable Natural Resource

In the current era of globalization, the development of concrete in the construction sector is very rapid, be it housing, offices, bridges, roads, dams, ports, and others. That is inseparable from the use of concrete as a part of building construction. The use of coarse aggregate for concrete mixes, namely natural stone, is a non-renewable natural resource. Therefore an alternative is needed as a substitute. One of the natural resources that can be renewed is hazelnut skin. Candlenut is a traditional plant that has various benefits, one of which is a candlenut shell. In this study, the materials used for standard concrete mixtures consist of water, cement, fine aggregate, and coarse aggregate. The water used for mixing the concrete is taken from the PDAM channel. The results showed that the effect of candlenut shells used as a substitute for some coarse aggregate decreased compressive strength results from the results of standard concrete compressive strength. The results obtained by the value of standard concrete compressive strength at 28 days of concrete were 27.19Mpa for concrete using Candlenut shells of 20% produce a compressive strength value of 17.33 Mpa at 28 days of concrete. 35% produce a concrete compressive strength value of 16.04 Mpa, while 50% produce a concrete compressive strength value of 15.17 Mpa. Thus the research shows that more and more candlenut shells are being used as a substitute for coarse aggregate in the concrete mixture.

This study assessed the significance of testing variables due to casting, curing, and breaking standard concrete compression test cylinders in three Saskatoon, Saskatchewan commercial testing laboratories. Analysis of the results indicated that these variables have a minor effect on the results when the laboratories have a 'good' rating. Nonuniformity of the concrete mix itself seemed to have the greatest influence on the within-test variation and caused the mean compressive strength in each laboratory to differ by ±4% of the overall mean strength of the mix.

Strength Result

Concrete railway sleeper has been used in Indonesia since about 1990�s. It has more advantage that is less maintenance, stabile, good quality, shapeable, onsite raw material, and higher loading ability [9-10, 20 - 22]. But It is prone to damage such as cracking and breaking during construction, so it is often thrown away as a solid waste that can contaminate the land and reduce soil fertility. Therefore, it should be utilized in order to be more useful that is used as recycle aggregate. The concrete waste that is taken from broken concrete railway sleeper will be crush as an aggregate as raw material in the concrete to substitute part or all of the normal concrete. It is called recycled aggregate and concrete that is made from recycled aggregate is called recycled concrete. Base on the testing of raw material, the recycled aggregate can be met to the specification as ASTM [1], so it can be used for concrete raw material. Recycled concrete compressive strength result lower the normal concrete compressive strength in the same initial strength design. The strength value of recycled concrete is decrease about 1 � 17% for 25 MPa and 10 � 18% for 30 MPa. It is also happened to tensile strength of recycled concrete that decrease about 2 � 13 % for 25 MPa and 7 � 22 % for 30 MPa.
