Beton geopolymer tersusun atas prekursor fly ash dan alkali aktivator (NaOH dan Na2SiO3). Selain prekursor dan alkali aktivator bahan campuran dalam beton geopolymer adalah zeolit. Geopolymer memiliki struktur yang mirip dengan zeolit. Penggunaan zeolit dapat mempercepat reaksi pengerasan beton dan meningkatkan kuat tekan. Pada penelitian ini dilakukan perbandingan metode pembuatan beton geopolymer terhadap sifat mekanik dan porositas. prosedur yang digunakan adalah metode pembuatan langsung, metode pembuatan terpisah dan metode penuangan langsung. Hasil yang diperoleh kuat tekan dan kuat tarik belah beton geopolymer tertinggi pada metode pembuatan terpisah yakni 40,89 MPa untuk kuat tekan dan 3,30 MPa untuk kuat tarik belah beton, sedangkan pada metode pembuatan langsung diperoleh kuat tekan sebesar 37,76 MPa dan kuat tarik belah sebesar 3,18 MPa, lalu untuk metode penuangan langsung diperoleh kuat tekan sebesar 36,08 MPa dan kuat tarik belah sebesar 2,62 MPa.

Jenis fondasi yang cocok untuk tanah di Pekanbaru adalah fondasi dalam (driven/bored pile). Perencanaan fondasi dalam umumnya menggunakan data properties tanah dan data pengujian lapangan. Data penyelidikan tanah yang populer untuk perencanaan fondasi dalam adalah Dutch Cone Penetration Test (DCPT) dan Standard Penetration Test (SPT) Pengujian DCPT juga sering disebut Sondir, yaitu alat uji terdiri dari kerucut penetrasi (qonus) untuk membaca tahanan ujung tiang dan Shaft resistance untuk menghitung tahanan kulit. Penelitian ini bertujuan untuk memperkirakan penurunan segera (intermediate settlement) fondasi tiang pada saat konstruksi dibangun. Artinya beban yang diterima tiap tiang tidak melebihi daya dukung tiang tunggal dengan faktor keamanan tertentu (SF=3). Data uji sondir berasal dari Laboratorium Mekanika Tanah Universitas Riau.

So that the two elements can be assembled into a building structure, it is necessary to do connection. Glued in rod is a new connecting tool whose mechanical properties still need to be studied. For this reasons this research was conducted. To achieve this objective, an experiment was conducted with the independent variables (1) the distance between the two edges, (2) the diameter of the threaded rod, and (3) the embedded length. The results showed that (1) the greater the distance between the two edges, the greater the pull out strength of the glued in rod, (2) the larger the diameter of the threaded rod, the greater the pull out of the glued in rod, (3) the greater the embedded length of the threaded rod, the stronger the pull out of glued in rod, (4) the value of the slip modulus is affected by variations in diameter and embedded length but is not affected by the distance between the two edges. The greatest pull out strength, which is 34.85kN, is achieved at a glued in rod diameter of 12mm with an edge distance of 4.5d and a embedded length of 6d, while the lowest value is 14.38kN lies in steel rods with a diameter of 8mm with a embedded length of 5d and a distance of two edges is 2.5d. The highest slip modulus or the highest stiffness value of 9.75kN/mm is achieved at a diameter of 12 mm with an embedded length of 6d and a distance of two edges of 3.50d.

Transportation problems that often occur include traffic jams and delays in travel time. Vehicle travel time as one of the service performance criteria at the intersection. These problems are often found in several areas in Indonesia, including at the intersection of Muharto St. – Mayjen Sungkono St. – Raya Ki Ageng Gribig St. is located in Malang city, which is the main route for large market vehicles to pass and is the road to access the center of Malang City as well as settlements and activities of the surrounding community. At this three-way unsignalized intersection, the traffic volume is large, so it can cause congestion at certain times. The purpose of this study was to determine the performance of Three-way unsignalized intersection Muharto st. – Mayjen Sungkono St. – Raya Ki Ageng Gribig St at 2021.

Jejawi is a village area located in OKI Regency and one of the livelihoods of its residents is gardening with the produce of Geda bananas, where after harvesting the banana stems are no longer used and become waste. This study aims to determine the effect of the utilization of Geda banana midrib ash in Jejawi Village as an added material on the quality of concrete. With experimental methods carried out in the laboratory, mixing the concrete material using the SNI quality standard K.225 and then adding variations of Geda Desa Jejawi banana ash which has been burned with an average temperature of 316oC by 2%, 2.5%, and 5%. From the test results, the compressive strength of normal concrete is 225.54 kg/cm2, the compressive strength of the banana ash variation of 2% concrete is 234.76 kg/cm2, the compressive strength of the banana ash variation of 2.5% concrete is 217.19 kg/cm2, and the compressive strength of the 5% banana ash variation of concrete is 203.64 kg/cm2. From the test results, there was an increase in compressive strength in the variation of the addition of 2% banana ash from normal concrete, but it decreased in the 2.5% banana ash variation and decreased again at 5%.
