Abstract

Research on the effect of temperature on concrete is still a hot topic. The effect of temperature was measured on its mechanical properties and analyzed using descriptive statistical analysis. The desire of researchers to know accurately the shape, description, and influence of temperature on concrete is something that still needs further research. The researchers began to research by making concrete test objects which were then burned directly in the furnace. After that, testing is done on the test object in the form of compressive strength. The research that was carried out was the remains of a burning building. But so far the assessment research has not yet found a strong starting point. Broadly speaking, the problem examined in this study is that researchers want to know the magnitude of high quality concrete mechanical degradation after being burned at a certain temperature and compared with high quality concrete that is not burned. These results are expected to provide a basis for the repetition of buildings that use high quality concrete that has been burned. The results of the mechanical degradation test reviewed were the average compressive strength of high quality concrete at a normal temperature of 53.46 MPa, a temperature of 100oC of 34.93 MPa, a temperature of 300oC of 29.76 MPa, a temperature of 600oC of 25.57 MPa.

Abstract

Penelitian ini bertujuan untuk menganalisis kebutuhan biaya operasi dan pemeliharaan pada daerah irigasi Pamukkulu serta menilai kinerja sistem irigasinya. Hasil perhitungan menunjukkan bahwa total biaya yang dibutuhkan untuk operasi dan pemeliharaan daerah irigasi Pamukkulu sebesar Rp 1.153.684.700. Selain itu, berdasarkan rekapitulasi penilaian, kondisi jaringan irigasi di daerah tersebut tergolong cukup baik. Berdasarkan analisis ini, disarankan agar kegiatan pemeliharaan dilakukan secara rutin dan berkala setiap tahun. Proses penyusunan nilai Angka Kebutuhan Nyata Operasi dan Pemeliharaan (AKNOP) harus mengikuti prosedur yang ditetapkan dalam Peraturan Menteri PUPR No.12/PRT/M/2015 guna memastikan efektivitas pelaksanaan operasi dan pemeliharaan irigasi.

Abstract

Land use changes in the Tanralili Sub-watershed have profoundly impacted its hydrological dynamics, leading to increased surface runoff and shorter return periods for peak flood discharges. Currently, a significant portion of the area, 75.51%, is dedicated to mixed dryland and wetland agriculture, leaving only 24.49% under forest or grass cover, which has rendered much of the land critical. This research examines the effectiveness of Biopore Absorption Holes (BAH) in mitigating flood risks by enhancing infiltration and reducing runoff. Experiments were conducted on soils with moderate permeability (0.00178 cm/s), utilizing PVC BAH units measuring 10 cm in diameter and 100 cm in length, equipped with biopores of ?10 mm. These units were installed in parallel on a 0.23% slope and tested under various rainfall intensities (I2, I5, I10), determined using the Mononobe equation, while peak discharge was estimated with the Nakayasu Synthetic Unit Hydrograph (HSS Nakayasu). The results showed a 58.80% reduction in peak flood discharge and a 62.99% increase in infiltration. These findings underscore the potential of BAH as an eco-friendly solution for flood mitigation. Expanding the use of BAH on open lands is recommended to bolster watershed resilience and tackle the growing risks of flooding.
