Abstract

increase while the supply is getting smaller so that it needs a partial substitute alternative to concrete mixtures to overcome the limitations of using natural materials. The purpose of this study is to find out how much influence the compressive strength results from the substitution of fine aggregate with sediment from the Bili Bili Dam. The method used in this study is an experimental method that refers to the SNI 7656-2012 testing standard. The variation in the sediment percentage in this study was 0%, 2.5%, 5%, 7.5% and 10% of the weight of the fine aggregate used. The concrete quality planned in this study is 14.53MPa and uses cylindrical samples measuring Ø15cm and 30cm high, as well as cubes with a width of 15cm and a height of 15cm. Based on the results of the study, the compressive strength value for the use of sediment as a substitute for some fine aggregate successively reduced the compressive strength of concrete during the age of 3, 7, 14, 28 days from the planned concrete quality to be reduced by 3.8%, 13.67%, 22.10%, 34.44% and 48.72%, the cause of reduction by the high mud content in the sediment.

Abstract

Pertumbuhan penduduk yang pesat di Kota Makassar mendorong peningkatan aktivitas ekonomi dan pembangunan, sehingga permintaan akan material konstruksi, khususnya beton, semakin tinggi. Melihat potensi bambu yang berlimpah di Indonesia, khususnya di Kota Makassar, penelitian ini bertujuan untuk mengeksplorasi penggunaan bambu sebagai alternatif dalam campuran beton. Bambu memiliki potensi untuk digunakan sebagai bahan tambahan atau pengganti sebagian agregat kasar dalam beton, yang dapat mengurangi penggunaan bahan non-daur ulang dan memberikan manfaat lingkungan. Meskipun penggunaan bambu dapat memberikan keuntungan seperti mengurangi berat jenis beton dan meningkatkan daya tahan terhadap retakan, pengaruhnya terhadap kekuatan tekan beton perlu diteliti lebih lanjut. Penelitian ini akan mengacu pada studi sebelumnya yang menunjukkan bahwa penggunaan bambu sebagai pengganti sebagian agregat kasar pada kadar di atas 10% mengalami penurunan kekuatan tekan. Oleh karena itu, penelitian ini akan menggunakan persentase kadar bambu sebesar 2%, 4%, 6%, dan 8% untuk mengevaluasi pengaruh bambu pada kekuatan tekan beton.

Abstract

Lakapera is one of the villages in Gu District, Central Buton Regency, Southeast Sulawesi. The people of Lakapera Village, Southeast Sulawesi Province, often use aggregates from the sea and mountains found in the village. This is due to the absence of a river in Lakapera Village which results in the use of sea sand aggregate and crafted stone of mountain stones as building materials. The purpose of this research is to provide information about the condition of aggregate characteristics from Lakapera Village that can be used as a mixture material in making concrete and to obtain how strong it is produced. The test piece process was made by replacing part of the local aggregate using sea sand and crushed stone from Mount Lakapera Village with a mixture percentage of 5%, 15%, and 30% on the 7, 14, 21, and 28 days of concrete age. Based on the result, the material characteristics of all aggregates are safe to use as concrete materials. The results showed that the compressive strength obtained decreased by a percentage of 2,20% of the test specimen (70:30%), from the initial compressive strength of 18,7MPa, in the 28 day concrete age test. The compressive strength of concrete using mixed materials 0%, 5%, 15%, and 30% at the 28-day age concrete was 19,50MPa with a percentage of 104,28% (Test specimen 100:0%), 18,75MPa or 100,29% (Test specimen 95:5%), 18,47MPa or 98,79% (Test specimen 85:15%), and compressive strength of 18,28MPa or 97,80% (Test specimen 70:30%) of the planned compressive strength.

Abstract

Discontinuous column is a column that doesn’t transfer the load directly to the foundation. The use of non-continuous columns includes irregular buildings because the location of the columns is not continuous so that the capacity of the columns is not vertically adjacent, and the result is that the load is quite large on the beams under the column. To carry the non-continuous column load, the beam is designed as a transfer beam, where the beam must be able to withstand the load above it, namely in the form of the beam's weight, gravity loads, earthquake loads, and also the column loads above it, then the loads that are carried will be transferred evenly to the two columns that carry the transfer beam. This study aims to determine the effect of non-continuous columns on the building structure and to determine the difference in concrete volume and reinforcement area that occurs. This research used 2 building models. The results showed that there was an increase in the volume of concrete in the non-continuous column by 13.088% for the column structure, 56.399% for the beam structure. For beam reinforcement area with dimensions of 25cm x 45cm, there was an increase of 59.029% for support reinforcement and 27.007% for field reinforcement. The 20cm x 30cm beam has an increase of 33.6% in support reinforcement and 46.2% in field reinforcement.
