Pemanfaatan Serat Limbah Hasil Anyaman Berbahan Bambu Sebagai Campuran Standard Mix Design Paving Block

Abstract

Exploitation of materials, especially the use of stones as themain component of concrete needs to be reduced. The existence of analternative to coral replacement as a coarse aggregate in a concretemixture needs to be applied. This research was conducted to find theoptimum percentage value of the addition of woven bamboo fiber as asubstitute of coarse aggregate to achieve the minimum compressivestrength according to standard mix design paving block. Thepercentage of absorption (absorption) is also observed, so that laterproduced paving with bamboo fiber which has a compressive strengthand absorption as well. This research use trial and error method,sample to be tested in the form of cube with size 15 x 15 x 15 cm asmany as 20 pieces with paving quality which is planned is K-225 or18,675 MPa. The percentage substitution ratio was derived from thevolume of the crude stone acting as a crude aggregate on the pavingblock mixture. Prior to its creation, several stages such as testing thematerial characteristics are performed. After that the test object ismade and tested at the age of 28 days. The method of makingspecimens is included in semi-mechanical using concrete mixer.Bamboo waste fiber is installed horizontally by layer by layer. Thetest results show the average compressive strength of bamboo fibervariation of 0%, 5%, 15% and 25% respectively by 20.7 MPa, 17.6MPa, 12.3 MPa and 9.9 MPa. From the result, it was found that thepercentage of bamboo woven fiber fiber is optimum in accordancewith the minimum standard limit of 17 MPa paving block by 7%.While the results of the absorption test in the sample showed aproportional increase with the percentage of woven bamboo fibervariation added, with an average absorption rate of 0.1%, 0.1%, 0.2%and 0,3%, while the optimum absorption is equal to 0,103%.Keywords: Absorption, Compressive strength, Paving block, Waste wovenbamboo fiber

Analisis Penanganan Limbah Konstruksi pada Proyek Pasar Tumburuni di Kabupaten Fakfak

“…Material sebagai bagian dari struktur bangunan mempunyai peranan penting dalam keamanan kerja. Selain itu ketersediaan bahan menjadi salah satu hal yang harus dalam setiap pelaksanaan pekerjaan, padahal dalam setiap proyek pembangunan gedung keberadaan limbah material tidak dapat dihindarkan, kejadian limbah material dapat berdampak buruk pada pelaksanaan proyek, khususnya di bidang konstruksi [2]. Penggunaan besi penguat seringkali menghasilkan residu yang jumlahnya tidak menentu.…”

Edukasi Pemanfaatan Limbah Sampah Plastik Menjadi Paving Blok

“…Proses pembuatan pavling block dimulai dengan pengumpulan sampah plastik dan pembakaran sampah sampai meleleh kemudian dicampur sedikit pasir dan oli bekas. Setelah itu adonan yang sudah jadi dicetak kedalam cetakan yang sudah dilumasi oli bekas agar tidak lengket lalu direndam kedalam air dan dilepaskan dari cetakan (Hardinsi, 2022) (Fauzy et al, 2018;Isradi et al, 2020;Siregar, 2021;Wahab & Nwanosike, 2020), seperti terlihat pada Gambar 9.…”

Pengaruh Variasi Campuran Serat Bambu Pada Kuat Tekan Beton Serat

“…Bambu Petung sebagai salah satu jenis bambu di Indonesia tepatnya di daerah Kalimantan, meskipun cukup jarang dibudidayakan secara khusus untuk keperluan konstruksi (Fauzy and Limantara, 2019) , namun bambu tetap banyak tumbuh di lahanlahan liar seperti di tepi sungai, tebing-tebing dan sebagainya. Bambu ini apabila diolah menjadi helaian serat berdiameter 1 mm diketahui memiliki berat jenis 0,8 N/m3 Kurniawandy (2015).…”
