Abstract

Salah satu sifat dari beton segar yang mempengaruhi kualitas beton ramah lingkungan yaitu workability dikaji dalam penelitian ini. Beton ramah lingkungan yang diteliti adalah jenis beton yang menggunakan limbah abu sekam padi (ASP) sebagai pengganti sebagian semen.Penelitian ini adalah penelitian eksperimental yang dilakukan pada Laboratorium Uji Bahan Jurusan PTSP FT UNM. Benda uji beton segar dibuat berdasarkan rancangan campuran mutu beton 20 MPa dengan fas 0.45. Persentase ASP yang digunakan adalah 0% , 5% dan 7.5% dari berat semen.Sifat workability ini diukur dengan 3 parameter yaitu hasil dari uji slump, faktor kepadatan dan bleeding. Berbeda dengan penelitian lain, semen yang digunakan adalah tipe Portland Composite Cement. Hasil penelitian menunjukkan bahwa semakin tinggi persentase ASP, maka nilai slump, faktor kepadatan dan bleeding semakin rendah. Hasil penelitian ini memberikan gambaran jelas mengenai pengaruh persentase abu sekam padi terhadap workability. Hal ini bermanfaat dalam penentuan jumlah air sehingga mendapatkan workability yang layak dalam menciptakan beton ramah lingkungan. Kata kunci: workability, ramah lingkungan, bleeding, faktor kepadatan, slump

Abstract

Abstract. This research aims to assess the environmental education integration model's effectiveness in improving elementary school students' knowledge and attitudes in science subjects. Efforts to integrate environmental education with subjects in elementary schools have developed to emphasize the importance of student knowledge development. However, limitations in time and learning achievement targets require carefully designed integration methods. This study is an experiment that applies the integration of Environmental Education (EE) with science lessons through video media and class discussions. This research is classified as quantitative research with a quasi-experimental approach. The population of this study consisted of 4th-grade elementary school students in Makassar City. The data analysis technique used was the pretest-posttest group design, and hypothesis testing was analyzed using the Paired Sample T-Test. The results of this study indicate that there is potential to support the integration model. Environmental Education integration material was selected by reviewing the science lesson planning documents and searching for relevant environmental issue news on electronic media. The findings revealed differences in students' knowledge and attitudes before and after receiving environmental education through the integration of science learning. The changes in students’ environmental knowledge and attitudes were also significantly different before and after the environmental education was provided.

Abstract

Abstract. The construction industry increasingly demands environmentally sustainable materials that reduce dependency on non-renewable resources. This study investigates the potential of rice husk ash (RHA) as a partial cement substitute and nickel slag as a fine aggregate replacement in the production of Cellular Lightweight Concrete (CLC) bricks. Both materials are industrial and agricultural wastes rich in silica, offering chemical and physical properties suitable for lightweight concrete applications. The research aims to evaluate the compressive strength of CLC bricks by incorporating RHA and nickel slag, with a particular focus on the influence of sand fineness. Three levels of sand gradation were tested, corresponding to Zone 2 (coarser), Zone 3, and Zone 4 (finest) based on sieve analysis. Specimens were cast and tested under standard conditions to assess their mechanical performance. The results indicate that sand fineness significantly affects the compressive strength of the bricks. Zone 2 sand produced the highest compressive strength (0.21 MPa), followed by Zone 4 (0.15 MPa) and Zone 3 (0.08 MPa). The decline in strength with finer sand is attributed to increased porosity and reduced interparticle friction, which disrupts bonding within the matrix. Furthermore, characterization results confirm that nickel slag fulfills the physical requirements of fine aggregates. This study demonstrates that combining RHA and nickel slag in CLC bricks is feasible and can support the development of more sustainable, non-structural construction materials with optimized mechanical performance. Keywords: CLC, rice husk ash, nickel slag, compressive strength, sand fineness

Abstract

Abstract. The main issue addressed in this study is the use of environmentally unfriendly concrete materials, such as gravel, which is a non-renewable resource. In addition, the production of cement used in concrete also contributes to air pollution. Therefore, innovation in more environmentally friendly construction materials is necessary, one of which involves using nickel slag waste as a partial replacement for coarse aggregates in green concrete. The proposed solution is the utilization of nickel slag, a by-product from the nickel smelting industry, as an alternative material to replace gravel in green concrete mixtures. This study aims to determine the optimum percentage of nickel slag as a substitute for gravel that can produce concrete with sufficient strength while maintaining environmental friendliness. The methods used in this research include testing the physical and chemical characteristics of nickel slag, producing concrete specimens with varying percentages of nickel slag, and conducting mechanical property tests such as compressive strength and slump tests to assess the performance of the resulting green concrete. The results show that using up to 50% nickel slag as a replacement for gravel in green concrete leads to a decrease in compressive strength, although the reduction is not significant. Additionally, the use of nickel slag can reduce the environmental impact of the construction industry by utilizing waste that had previously been underutilized. The application of nickel slag as a partial replacement for coarse aggregates in green concrete offers a promising solution for creating more sustainable construction materials. Keywords: green concrete, nickel slag, coarse aggregate, compressive strength, environmentally friendly

Abstract

Abstract. This study aims to analyze the effect of nickel slag as a partial replacement for fine Aggregate on the mechanical and physical properties of Cellular Lightweight Concrete (CLC). The research employed an experimental laboratory method, with nickel slag contents of 0%, 2.5%, 5%, 7.5%, and 10%. Tests were conducted on compressive strength, flexural strength, and water absorption according to SNI standards. The results show that incorporating nickel slag up to 7.5% increased compressive strength from 0.687 MPa to 1.221 MPa, representing a 77.7% improvement compared to the control mix. The flexural strength remained relatively stable between 1.323 kN and 1.385 kN, indicating that slag addition had no significant effect on flexural behavior. In contrast, water absorption decreased by 24.4%, from 20.575% to 15.544%, suggesting reduced porosity due to the micro-filler effect of fine slag particles. The optimum slag content was 5–7.5%, providing the best balance between mechanical strength and water resistance. Technically and practically, using nickel slag as a partial sand substitute presents a promising approach for developing eco-friendly lightweight concrete, supporting green construction and circular economy concepts

Abstract

Abstract. This study evaluates the effect of immersion duration and water acidity on the compressive strength and porosity of autoclaved lightweight concrete (ALC) bricks. The experimental work was conducted by immersing samples in both normal and acidic water for 7, 14, and 28 days. A total of 260 samples were tested, including 140 specimens for compressive strength and 120 for porosity analysis. Normal water had a pH of 6.5–8.5, while acidic water was adjusted to a pH of 4–5 using nitric acid. The results show a consistent decline in compressive strength with increasing immersion time. The average compressive strength decreased from 2.87 N/mm² (without immersed) to 1.30 N/mm² after 28 days of immersion in normal water, and to 0.40 N/mm² after immersion in acidic water for the same period. Correspondingly, the porosity increased from 18.05% to 32.08% under normal conditions and from 24.24% to 41.04% in acidic conditions. These findings indicate that immersion, particularly in acidic environments, accelerates the degradation of lightweight bricks through calcium leaching, dissolution of cementitious compounds, and pore structure expansion. The study concludes that the durability of lightweight bricks is highly dependent on environmental exposure. Acidic water immersion causes severe chemical and physical damage, reducing both strength and cohesion. Protective surface treatments and improved mix design are therefore recommended to enhance the resistance of lightweight bricks against water and acid-induced deterioration. Keywords: lightweight brick, compressive strength, porosity, immersion, acid attack, durability
