Abstract

Transportasi merupakan salah satu elemen pendukung yang penting dalam pembangunan Negara dan salah satu sistem transportasi yang merupakan penghubung antar daerah adalah jalan. Oleh karena itu perlu adanya inovasi-inovasi dalam perancangan perkerasan jalan yang berkelanjutan agar tercipta kondisi jalan yang baik. Sebagaimana diketahui Laston (AC-WC) adalah merupakam bahan campuran aspal jenis perkerasan lentur yang terdiri dari campuran agregat dan aspal, dengan atau tanpa bahan tambah . Susunan gradasi agregat menerus pada Laston ini menyebabkan banyak digunakan untuk perkerasan jalan dengan klasifikasi lalu-lintas berat serta diutamakan untuk digunakan pada daerah tropis sehingga banyak diterapkan di Indonesia. Untuk mendapatkan campuran aspal beton yang yang sesuai dengan susunan gradasi yang disyaratkan maka digunakanlah filler yang berfungsi sebagai bahan pengisi, misalnya semen, ataupun debu abu batu, dalam hal ini kesemua material tersebut adalah material yang tidak dapat diperbarui, untuk itu perlu inovasi-inovasi lebih lanjut untuk mencari material alternatif pengganti filler, dalam penelitian ini digunakan variasi filler limbah balon gas. Dari hasil penelitian dapat disimpulkan bahwa nilai stabilitas Laston WC dengan menggunakan Limbah Balon Gas lebih tinggi dibandingkan dengan Semen sebagai Filler kenaikan nilai stabilitas sebesar 14,98 %, walaupun nilai flow kecil namun nilai VIM, VMA dan VFB lebih kecil sedikit , namun emua nilai karakteristik tersebut masih sesuai dengan spesifikasi.

Abstract

The use of SCC (Self Compactibility Concrete) concrete in Indonesia is increasing in the field, especially for a variety of buildings that require large compaction speeds or use concrete that can compact itself. SCC Concrete Technology in the construction industry is growing, especially in meeting the needs of the construction world. Added material is an alternative material used to increase the strength characteristics of the concrete. Likewise the addition of glass powder waste, and bauxite waste in making SCC concrete is expected to increase the compressive strength concrete. Fresh concrete, which belongs to the self-compacting concrete (SCC) group, has a very high slump value (more than 20 cm), so measurements with cone abrams are no longer effective. The use of these materials as substitute materials and added based on the thought to utilize glass waste and , bauxite waste in order to reduce the impact of environmental pollution and provide economic value. This study uses glass powder as glass waste and bauxite waste as added material for cement. This study uses four kinds of mixed compositions, namely 0% (ordinary concrete); 2.5% mixture; 5% and 7.5% by weight of cement as added material from glass waste and bouksit waste, where each composition consists of 3 cylindrical specimens with a diameter of 15 cm and a height of 30 cm. Until now there has never been any research from mananpun to test the 2 (two) mixtures, therefore we want to test it so that glass waste and bauxite waste are not wasted and can be reused, especially in making SCC concrete. From the research results it was found that the maximum slum cone test results were in the 2.5% variation that is equal to 44.3 cm, while the minimum at 0% was 29.3 cm. The maximum compressive strength at the age of 3 days is 455,418 kg / cm2 for variations of 7.5% while the minimum is at a variation of 2.5% of 200.469 kg / cm2 at 7 days of concrete.

Abstract

As a result of the COVID-19 Pandemic Outbreak, proper living for slum dwellers has become increasingly difficult, the income level of the population has decreased so that areas where slum areas were not identified at first may increase the spread of their territory. According to the Decree of the Regent of Sambas Number 872 / BAPPEDA of 2014 concerning the Determination of the Location of Housing and Slum Settlements in Sambas Regency, the slum settlement area covering an area of ​​75.77 ha is spread over 3 sub-districts covering 4 villages. Namely Pendawan Village, Tanjung Bugis Village in Sambas District, Penjajab Village, Penjajab District and Sekura Village, Sekura District. Of the 4 villages that occupy the largest area for slum areas is Tanjung Bugis Village with an area of ​​23.05 ha (30.42%). This study aims to identify the factors that cause slum areas in Sambas Regency, identify facilities and infrastructure, especially environmental roads, garbage, wastewater and housing, analyze the needs for facilities and infrastructure from the data obtained in the form of roads, to, clean water and housing. This research was conducted deductively, so that the researchers departed from theory to go into the field in conducting data searches which were then expected to analyze the facilities and infrastructure needs of the slum area in Sambas City. .From the results of this study, it is found that the factors that cause slum are insufficient income of Rp. 500,000 - Rp. 1,000,000.00, the last education is very low elementary school (elementary school) and the number of families between 3-5 people. Meanwhile, from the analysis of the need for facilities and infrastructure, appropriate technology is needed for community water sources that still use public taps, environmental roads use concrete rebates but many are still damaged, drainage channels are not there if the water is not smooth or jammed while the trash can is not owned, especially TPS (Temporary Disposal Site) for garbage.

Abstract

Concrete is a significant substance that is frequently employed in infrastructure construction. When manufacturing concrete, a concrete mix, or Design Mix Formula (DMF), must be created to specify the proportions of the materials to achieve the desired concrete quality. Concrete quality is classified based on the compressive strength of the concrete, which value has a significant impact on the DMF produced. One of the factors that can affect the quality of concrete is the fact that the dosage used in making concrete in the field is not in accordance with the existing DMF. This means the quality of the concrete in the field is not in accordance with what was planned, namely the quality of K-300 concretes. This study's objectives are to assess the current DMF and examine the variables influencing concrete quality in the field. To conduct the research, the Pontianak State Polytechnic's Civil Engineering Concrete Laboratory tested aggregates, created DMF, created cube specimens, and tested cube concrete compression tests. As a result, it can be said that one DMF can be used for all these structures because the laboratory results demonstrate that the DMF utilized in the field is consistent with the intended concrete quality, namely K-300 concrete quality. At the age of 28 days, concrete with a slump value of 9 cm had an average compressive strength of 339.882 kg/cm2, or 28.21 MPa. According to the findings of these investigations, the field-related factors cause the quality of the concrete to differ from the planned concrete's quality.

Abstract

Until now, bauxite waste (bauxite tailings) has not been utilized in its entirety, causing an increase in the amount of waste in the bauxite producing areas. The percentage between the bauxite produced and the amount of waste produced is 50%: 50%. This research was conducted to see whether or not the use of liquid waste (tailings bauxite) is appropriate as a place for fine aggregate in the manufacture of concrete. This study used an experimental method with the replacement of the concrete mixture, namely sand with bauxite waste (bauxite tailings) with the proportion of bauxite waste (bauxite tailings) of 2.5%, 5%, and 7.5%. The tests carried out were compressive strength testing, split tensile strength testing, and modulus of elasticity. The results of the test for the highest compressive strength average age of 7 days were found in normal concrete with an average compressive strength of 21.58 MPa. The average compressive strength of 28 days was 7.5% bauxite waste concrete with an average compressive strength of 32.07 MPa. The tensile strength of 7 days was in bauxite waste concrete at 7.5% with a split tensile strength of 2.90 Mpa. The tensile strength of 28 days was in bauxite waste concrete 7.5% with a split tensile strength of 3.26 Mpa. The highest average modulus of elasticity is found in 7.5% bauxite waste concrete with a yield of 26607.03 Mpa, Keywords: Bauxite Waste (Tailing Bauxite), Compressive Strength, Modulus of Elasticity, Split Tensile Strength
