Abstract

The banner will be taken down after the permit expires, leaving only a pile of trash in its place. This study investigates the compressive strength and tensile strength of concrete through the addition of banner fiber waste in concrete mixtures with various percentages, namely 0%, 1%, 3%, and 5%. The method used is an experiment in a quantitative research approach. The test specimens made in this experiment are concrete cylinders. The results of the study on the variation of plastic banner waste addition in the form of rectangular pieces and percentage variations of 0%, 1%, 3%, and 5% yielded an average compressive strength of 0% (normal concrete) of 18.284 MPa. The addition of 1% plastic banner waste resulted in an average compressive strength of 15.338 MPa. The average compressive strength was 13.947 MPa with the addition of 3% plastic banner waste. And with the addition of 5% plastic banner fiber waste, the average compressive strength value was 5,420 MPa. Thus, it can be concluded that concrete with 0% plastic banner fiber waste (normal concrete) has a better compressive strength value compared to concrete with 1%, 3%, and 5% plastic banner fiber waste.

Abstract

An effective strategy to improve the drainage system on Cimedang Street by integrating local expertise and resources can reduce the negative impacts of rainwater accumulation. A collaborative approach from local government, universities, and communities is actively involved in building effective drainage solutions in Bendo Village. The targeted community service activity is supervising the rehabilitation of the Cimedang Street drainage channel. The supervision results illustrate that the implementation of the Cimedang Street Drainage Channel Rehabilitation is ahead of schedule, which is completed in the seventh week with a cumulative realization of 100% of the cumulative planned weight of 42.33%. Testing of materials such as concrete and aggregates shows results that meet technical specifications and test results with concrete compressive strength of 3 samples with a compressive force of 495.9-530.4 KN with a cylinder compressive strength of 28.06-30.01 MPa. This activity results in an adequate acceleration of time realization of 57.67% and concrete compressive strength test results of>20 MPa.ABSTRAKStrategi yang efektif dalam peningkatan sistem saluran air di jalan Cimedang melalui penggabungan keahlian dan sumber daya lokal dapat mengurangi dampak buruk dari akumulasi air hujan. Pendekatan kolaboratif dari pemerintah daerah, perguruan tinggi dan masyarakat yang secara aktif terlibat untuk membangun solusi saluran air yang efektif di kelurahan Bendo. Kegiatan pelayanan masyarakat yang ditargetkan adalah pengawasan rehabilitasi saluran air jalan Cimedang. Hasil pengawasan menggambarkan pelaksanaan Rehabilitasi Saluran Air Jl. Cimedang lebih cepat dari jadwal yaitu selesai pada minggu ke 7 dengan kumulatif relisasi bobot 100% dari Komulatif bobot rencana sebesar 42,33%. Pengujian material seperti beton dan agregat menunjukkan hasil yang memenuhi spesifikasi teknis dan hasil uji dengan kekuatan tekan beton 3 sampel dengan gaya tekan 495,9-530,4 KN dengan kuat tekan silinder 28,06-30,01 Mpa. Kegiatan ini menghasilkan efektifitas percepatan realisasi waktu sebesar 57,67% dan hasil uji kuat tekan beton yang >20 Mpa.
