Building and non-building construction generally uses reinforced concrete using conventional methods. Over time, this method has evolved and given rise to other approaches such as precast and prestressed methods. However, these methods still have some drawbacks, such as the relatively high density of the material and its impact on other aspects of the structure. New innovations are emerging to solve these problems, such as super lightweight panels with a material density of around 650 kg/m3. This study aims to examine other structural components, namely beam and column structures by comparing the reinforcement requirements and deviation of two buildings with different types of floor plates. The tests were conducted using an analytical approach using ETABS software. The results showed that the average ratio of beam reinforcement between superpanel plate and conventional plate was 77% and column was 94%. The average ratio of X-direction deviation between superpanel plate and conventional plate is 94% and Y is 88%.

Limbah fly ash dari Pembangkit Listrik Tenaga Uap (PLTU) Lontar, Serang, Banten, merupakan sisa pembakaran batu bara yang berpotensi mencemari lingkungan jika tidak dikelola dengan baik. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk memanfaatkan limbah tersebut melalui pelatihan pembuatan paving block bagi warga Desa Lontar. Metode yang digunakan dalam pelatihan meliputi pemberian teori dan praktik langsung mengenai persiapan bahan baku, pencampuran material, teknik pencetakan, serta pengeringan paving block. Pelatihan juga menekankan pentingnya keselamatan kerja dan pengelolaan lingkungan selama proses produksi. Hasil dari kegiatan ini menunjukkan peningkatan keterampilan warga dalam memanfaatkan fly ash menjadi paving block yang bernilai ekonomis. Beberapa peserta berencana mengembangkan produksi ini secara mandiri, baik untuk memenuhi kebutuhan desa maupun untuk dijual ke pasar yang lebih luas. Kegiatan ini diharapkan dapat meningkatkan kesejahteraan ekonomi masyarakat sekaligus mengurangi dampak negatif limbah industri terhadap lingkungan.

In some building designs that carry a high aesthetic or architectural value, the use of flat columns brings a number of significant advantages. Their slender design provides more flexibility in interior layout and adds to the aesthetic value of the building. This study was conducted to determine the reinforcement requirements and behavior of flat columns as well as checking the displacement in accordance with SNI 1726:2019. The results show that column I and column L are categorized as swaying and long columns, while column T and column Plus are included in the category of non-swaying and short columns. The required reinforcement requirements are as follows: For column I with dimension 130 x 800, 10D16 main reinforcement is required with D10-100 mm stirrups inside the plastic joint area and D10-150 mm outside the plastic joint area. Column L of dimension 130 x 500 requires 16D16 main reinforcement with D10-100 mm stirrups both inside and outside the plastic joint area. T columns of dimension 130 x 500 require 10D16 main reinforcement with D10-100 mm stirrups inside and outside the plastic joint area. Plus columns of dimension 130 x 400 require 12D16 main reinforcement with D10-100 mm stirrups inside and outside the plastic joint area. The maximum defelction that occurs is still within the permissible tolerance limits of 15.32 mm in the X direction and 11.15 mm in the Y direction so that the building structure is declared safe and stable against the loads received in accordance with SNI 1726: 2019.

Efficiency in structural design is important to optimize the use of materials and costs, while maintaining strength and stability to ensure the safety of the building. With construction design regulations constantly updated, careful and precise planning calculations are crucial. This study identifies overdesign in columns, beams, and foundations of existing buildings, and aims to determine more optimal and efficient dimensions and repetitions, resulting in stronger, more economical, and standard-compliant buildings. The research was conducted in a 4-storey office building with dimensions of 32 x 15,725 meters will be analyzed based on SNI 2847:2019, SNI 1726:2019, and SNI 1727:2020. The analysis was carried out using Microsoft Excel and ETABS. The results of the study showed that there was overdesign in the main column, main beam, and foundation. On a beam of 400mm x 650mm it produces an efficiency of 17.46%. The bending reinforcement requirement results in an efficiency of 21.785%. Meanwhile, the shear reinforcement and middle reinforcement are the same as the initial planning. In a 450mm x 700mm column it produces an efficiency of 16%. For shear reinforcement, an efficiency of 10% is obtained. As for the bending reinforcement, it is the same as the initial planning. In the foundation design, 4 square piles with dimensions of 450mm x 450mm and pilecap dimensions of 2600mm x 2600mm x 500mm with reinforcement requirements for the x direction D22-100 and the y direction D22-125. Resulting in a pilecap volume efficiency of 28.888%.

Road construction planning must consider the characteristics and strength of the soil. This study aims to determine the classification of soil and the effect of fly ash-based geopolymer as an added material on the specific gravity of soil. Specific gravity testing was carried out using a pycnometer to obtain the specific gravity of the soil. The test object used is a soil sample added with geopolymer with fly ash as raw material and an alkaline activator (Na2SiO3and NaOH). The NaOH concentration is 10 M with a solution ratio of 2.0 (Na2SiO3 to NaOH), fly ash content of 20%, and variations in S / L (fly ash to activator) levels of 1/2 and 1/2.5. Based on the research that has been done, the results show that the soil used in the study is included in the organic clay soil with a specific gravity value of 2.49. The effect of fly ash-based geopolymer in this study increases the specific gravity value, with a specific gravity of 2.60 for variation B (80% soil, 20% FA, S/L 1/2) so that the soil falls into the organic clay category and 2.69 for variation C (80% soil, 20% FA, S/L 1/2.5) so that the soil falls into the non-organic clay category.
