Abstract

Foam concrete is a concrete technology that is applied to buildings. The advantage of foam concrete is that it is lightweight and fast in building work. The use of foamed in foam concrete reduces the density of foam concrete. Substitution of fly ash for cement can increase the compressive strength of foam concrete. The variations of foamed used in this study were 30%, 40%, and 50%. The substitution of fly ash for cement in this study was 0%, 5%, and 10%. In the specific gravity test, the smallest value was 1,156 kg / m3 resulting from a variation of 50% foamed and 0% substitution of fly ash for cement, while the largest weight was 1,670 kg / m3 resulting from 30% foamed variation and 10 fly ash substitution. % against cement. In the compressive strength test at 28 days of concrete, the highest value was obtained with a value of 2.573 N / mm2 resulting from 30% variation of foamed and 5% substitution of fly ash for cement, while the lowest compressive strength was 1.986 N / mm2 resulting from variations of foamed 30 % and 10% substitution of fly ash for cement. The optimum composition of foam concrete in this study was found in a mixture with 40% foamed variation and 5% fly ash substitution for cement with a value of 2,312 N / mm2 and a specific gravity of 1438 kg / m3. The optimum use of fly ash is obtained at a substitution percentage of 5% for cement. Foam concrete using styrofoam and polypropylene fibers is good for non-structural elements in buildings such as wall panels. Keywords: Light weight concrete, foamed concrete, fly ash

Abstract

Banyuasin tidak hanya sebagai penghasil padi terbesar di Sumatera Selatan tetapi juga penghasil kelapa terbesar di Sumatera Selatan. Namun hilirisasi produksi perkebunan kelapa belum banyak dilakukan di kabupaten pemekaran Musi Banyuasin. PT. Kulaku Indonesia sejak 2018 telah memproduksi produk turunan kelapa seperti minyak kelapa (VCO), sirup, santan, arang, asap cair, dan nata de coco dengan kapasitas produksi mencapai dua ton perbulan. Kantor Perwakilan Bank Indonesia Provinsi Sumatera Selatan telah melaksanakan beberapa program kerja untuk pengembangan ekonomi dan keuangan syariah diantaranya pengembangan kemandirian ekonomi pondok pesantren melalui peningkatan peningkatan kapasitas dan kualitas UMKM Syariah melalui program Industri Kreatif Syariah Indonesia (IKRA). PT. Kulaku Indonesia bersama Ponpes Sabilul Hasanahagar Banyuasin dengan binaan Bank Indonesia (BI) berencana membuat produk turunan kelapa berupa santan bubuk. Untuk memproduksi santan bubuk diperlukan tempat yang steril dan suhu yang terjaga, sehingga diperlukan perencanaan pembangunan Pabrik Santan Bubuk.Kata kunci : Perencanaan Pembangunan Pabrik, RAB.

Abstract

Abstract:  the waste of fraction bricks and tile fragments for mixing in concrete in Indonesia is stil not widely used in heavy-duty construction buildings. For this reason, this study aims to determine the compressive strenght of concrete by utilizing waste brick and tile fragments as a substitute for coarse aggregate. This test has several stages, namelu material testing, making test objects, testing concrete compressive strength, and analyzing test results. In this test, the specimens were molded using a cylinder with a mixture of substituting brick fragments and tile framents against coarse aggregate with variasions of 5%, 10% and 15%. The results of the compressive strenght test on norma unmixed concrete with a 5% age of 28 days obtained a value of 16,6 MPa, on concrete with a 5% variation of brick and tile with an age of 28 days a value of 12,41 MPa was obtained, on a concrete variatio  of 10% brick an tile. The obtained value is 11,98 MPa, and in the 15% variation concrete mixture of brick and tile, the value is 11,54MPa. Keywords:  Compressive Strength of Concrete, Coarse Aggregate, Waste fractions Brick and Tile.  Abstrak: Limbah pecahan batu bata dan pecahan genteng untuk campuran dalam beton di Indonesia memang masih belum banyak untuk digunakan dalam bangunan kontruksi yang terbeban. Untuk itu penelitian ini bertujuan untuk mengetahui kuat tekan beton dengan memanfaatkan limbah pecahan batu bata dan pecahan genteng sebagai subtitusi agregat kasar. Pengujian ini ada beberapa tahapan, yaitu pengujian material, pembuatan benda uji, pengujian kuat tekan beton, dan analisa hasil pengujian. Pada pengujian ini benda uji dicetak menggunakan silinder dengan campuran subtitusi pecahan batu bata dan pecahan genteng terhadap agregat kasar dengan variasi 5%,10%dan 15%. Hasil uji kuat tekan pada beton normal tanpa campuran dengan umur 28 hari didapat nilai sebesar 16,6 MPa, pada beton dengan variasi 5% bata dan genteng dengan umur 28 hari didapat nilai sebesar 12,41 MPa, pada beton variasi bata dan genteng 10% didapat sebesar 11,98 MPa, dan pada beton variasi 15% campuran bata dan genteng didapat nilai sebesar 11,54 MPa. Kata kunci: : Kuat Tekan Beton, Agregat kasar, Limbah Pecahan bata dan pecahan genteng.

Abstract

Concrete is a very important construction material and has good compressive properties. According to its mass, concrete is divided into ordinary concrete and lightweight concrete. Light weight concrete is 1000-2000 kg/m3. In high construction projects the use of lightweight concrete can reduce the mass of the building itself. The latest innovation in lightweight concrete is the addition of kaolin as a cement substitute. Kaolin is a clay or clay mineral that contains a lot of aluminum silica. Stryofoam is one of the materials that can be used in lightweight concrete mixes. The use of kaolin and styrofoam waste is sought to support construction materials that are more environmentally friendly. The purpose of this study was to determine the effect of the addition of kaolin on compressive strength so that it can be used as an admixture in lightweight concrete. The results showed that the weight of concrete mixed with 5%, 10%, 15% kaolin and 60% Styrofoam at the age of 28 days was 1836 kg/m³, 1845 kg/m³, 1852 kg/m³. The average compressive strength for the kaolin variants 5%, 10%, 15% were 8.28 MPa, 8.46 MPa, 10.11 MPa. Based on this it was concluded that concrete using a mixture of kaolin and 60% stryofoam can be used in light construction. Because the weight of the lightweight concrete tested was lower than normal concrete and met the specified requirements, namely the specific gravity of the resulting concrete was in the range of 1000-2000 kg/m³.

Abstract

Pembangunan infrastruktur memacu kebutuhan akan beton yang semakin meningkat sehingga mengakibatkan meningkatnya kebutuhan material pembentuk beton. Pada penelitian ini dilakukan pengujian menggunakan fly ash dan aditif sikacim sebagai bahan tambah pada campuran beton guna mengetahui kuat tekan beton maksimal yang dihasilkan. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan fly ash sebagai bahan subtitusi semen pada campuran beton dan karakteristik beton dengan variasi 0%, 8%, 10% dan 12% terhadap kuat tekan beton. Metode yang digunakan pada penelitian ini adalah metode eksperimen. Pada penelitian menghasilkan nilai kuat tekan beton tertinggi sebesar 27,91 MPa dengan penggunaan fly ash 8% sebagai substitusi semen dengan zat adiktif sikacim 0,6%. Namun setiap penambahan persentase fly ash menyebabkan terjadi penurunan kuat tekan beton. Hal ini terjadi dikarenakan penggunaan semen yang disubstitusi oleh fly ash menjadi lebih sedikit

Abstract

Roads are the infrastructure that sustains the growth of the economy and plays a very important role in the progress and development of a region. Asphalt functions as a binder in asphalt mixes, making it important to maintain its stickiness, softness, and pliability. Adding additives to asphalt is an alternative that can be used to maintain or increase the grip, soft point, and flexibility of the asphalt. Used motor vehicle tires are made from a variety of materials such as natural rubber, neoprene, chemicals, carbon black and certain oils. The characteristic of rubber is that it is durable and flexible or elastic. This study aimed to determine the value of Optimum Asphalt Content (KAO) in AC-WC mix using modified bitumen with wheel powder with 1% and 2% variations. The results of this study show the results of parametric data analysis for each KAO that the optimum value of the 3 KAOs is 6.18% with the addition of 1% asphalt + rubber tire powder. The parameter values are VIM 4.61%, VMA 18.52%, VFA 75.31%, Stability 1459 kg, and Flow 2.95 mm.
