Abstract

Perkembangan dunia teknik sipil mengalami kemajuan yang sangat pesat di era society 5.0 dan gencarnya pembangunan infrastruktur di tanah air. Beton SCC merupakan beton yang inovatif yang tidak memerlukan getaran ataupun alat pemadat karna baton SCC dapat memadat sendiri. Banyaknya kebutuhan akan material menyebabkan terjadinya penambangan ilegal yang akan merusak lingkungan. Oleh karena itu, perlu adanya alternatif lain untuk mengurangi eksploitasi alam yang semakin lama akan berdampak buruk bagi lingkungan. Tujuan dari penelitian ini yaitu pemanfaatan serbuk cangkang telur dan serbuk granit digunakan sebagai subtitusi agregat halus, limbah beton digunakan sebagai subtitusi agregat kasar. Material serbuk cangkang telur berasal dari limbah cangkang telur yang telah dihaluskan dan memiliki kandungan kalsium karbonat (CaCO3) tinggi. Dalam proses produksi granit, 30% dari setiap lempengan berubah menjadi lumpur batu. Limbah tersebut sering dimuat ke dalam truk untuk dibawa pergi dan dibuang ke alam. Limbah beton adalah material sisa beton yang sudah tidak terpakai lagi untuk konstruksi.. Hasil pengujian yang dilakukan menunjukan hasil optimum masing-masing inovasi adalah 40% serbuk cangkang telur, 20% serbuk granit dan 20% limbah beton. Okamura dan Ouichi menyatakan bahwa dalam pembuatan beton SCC, agregat halus harus lebih tinggi daripada agregat kasar. Inovasi beton SCC ramah lingkungan menggunakan serbuk cangkang telur, serbuk granit, dan limbah beton mampu menghasilkan kuat tekan >41,4 MPa dan dapat menghemat biaya Rp. 407.739 /m3 dari harga beton SCC tanpa menggunakan inovasi atau setara dengan 25,92 % lebih ekonomis. Kata kunci: Self compacting concrete, beton ramah lingkungan, serbuk cangkang telur, serbuk granit, limbah beton, ekonomis.

Abstract

Micro Hydro Power Plant (PLTMH) is one of the solutions in meeting the needs of renewable energy, especially in remote areas that have abundant water resource potential. This study aims to analyze slope stability and analyze the budget plan for building a retaining wall with a cantilever wall or gravity wall type. The method used in this study is using GEO5 software and calculating the budget plan (RAB). The results of this study using retaining wall analysis using GEO5 Software with the Cantilever Wall type get the Safety Factor results: 1.87> 1.10, the results of retaining wall analysis using GEO5 Software with the Gravity Wall type get the Safety Factor results: 2.03> 1.10. And the results of the RAB recapitulation using the Cantilever Wall type compact the results: Rp 6,469,724,186, and the results of the RAB recapitulation using the Gravity Wall type compact the results: Rp 2,445,607,393. So the most efficient RAB result is using the Gravity Wall type.

Abstract

This study investigates the potential of incorporating calcium carbonate (CaCO?) as a partial replacement for cement, pumice powder as a substitute for fine aggregates, and molasses as a natural retarding admixture in the development of structural lightweight concrete. The research is motivated by the growing need for sustainable, low-density construction materials that are suitable for seismic regions such as Indonesia. An experimental approach was adopted, involving laboratory testing of compressive strength and density at curing ages of 7, 14, and 28 days. The evaluation criteria were based on the Indonesian National Standard (SNI 2847:2019), which specifies a minimum compressive strength of 17.24 MPa and a maximum density of 1840 kg/m³ for structural lightweight concrete. The experimental results demonstrated that the proposed material combinations successfully met the required standards. The optimum mix composition consisted of 10% CaCO? by weight of cement, 40% pumice powder by total fine aggregate, and 0.2% molasses. Among the tested variations, the BR-40% mixture achieved a compressive strength of 27.03 MPa and a density of 1824 kg/m³, while the BR-50% mixture yielded 24.53 MPa and 1710 kg/m³, respectively. These findings confirm the feasibility of using such innovative materials to produce lightweight concrete with enhanced structural performance and improved sustainability

Abstract

Infrastructure growth is in line with the growth of human resources, the more the population will require more infrastructure facilities. Construction infrastructure in Indonesia is currently starting to focus on development that leads to the use of structures with lightweight materials and has high resistance. This is inseparable from Indonesia's geographical location which is on the Pacific Ring of Fire which makes Indonesia prone to earthquakes. Therefore, it is necessary to conduct research on lightweight concrete that can overcome these potential hazards. This study used lightweight brick powder, bagasse ash and fly ash in replacing concrete materials. The method used is experimental by creating variations of lightweight concrete by adding lightweight brick powder amounting to 70% of the volume of fine aggregate. The results of the optimal content of bagasse ash use are 10% and fly ash 15% of the total cementitious. Testing of lightweight concrete variations was carried out on concrete aged 7, 14, 21 and 28 days. On lightweight concrete aged 28 days, a comparison was made with normal concrete. The results of the test weight of lightweight concrete aged 7, 14, 21 and 28 were 2.89 kg; 2.83 kg; respectively. 2.80 kg and 2.79 kg. The results of the lightweight concrete compressive strength test at the age of 7, 14, 21 and 28 were 16.54 MPa, 22.27 MPa, 25.25 MPa and 26.74 MPa, respectively. The resulting density ratio was 1743 kg/m3 for lightweight concrete and 2283 kg/m3 for normal concrete. The resulting compressive strength comparison from the creation of lightweight concrete at the age of 28 days from 3 test specimen samples was 26.74 MPa, 27.37 MPa and 26.10 MPa, respectively, while in 3 normal concrete samples the values were 24.19 MPa, 24.83 MPa and 26.10 MPa.
