On the other hand, the increase in the growth of construction service companies has not been accompanied by a good atmosphere of construction implementation. As a result, delays in completing work have become commonplace in construction projects in Indonesia, the eastern part, and especially Papua. This research investigated the factors causing delays in completing construction work in Papua Province, especially in Merauke Regency. Questionnaires were distributed to contractors registered as members of GAPEKSINDO and domiciled in the Merauke district. The purposive sampling technique took the number of samples. The data analysis in this research used a Non-Parametric Statistical Test with Kendall's W analysis using SPSS 25.0 for the Windows program. The seven main factors that cause construction project delays are related to consultants. The test results show that the main factor of delay in construction projects in the Merauke Regency is the labor factor, with a mean rank value of 2.56. Factors that do not affect construction delays are other factors with a mean rank value of 5.28.</em></p> Anggara Hutahaen Arief Setiawan Budi Nugroho Muslikh Copyright (c) 2022 Teknisia 2022-06-18 2022-06-18 27 1 1 11 10.20885/teknisia.vol27.iss1.art1 PENGARUH PENAMBAHAN REDISET LQ-1106 TERHADAP KINERJA STRUKTUR CAMPURAN ASPAL PORUS https://journal.uii.ac.id/teknisia/article/view/19295 <p><em>Porous asphalt is an asphalt mixture with high porosity to reduce the potential waterlogging and increase the roughness of the road surface. However, porous asphalt mixture has shortcomings in terms of strength and durability. This paper presents laboratory testing results of the effect of adding Rediset LQ-1106 additive on the performance of a porous asphalt mixture. The research was started with the determination of the optimum asphalt content. Then, the test object was made with Rediset LQ-1106 using variations in 0%, 1%, 2%, and 3% of the optimum asphalt content and carried out the Marshall test, Immersion Test, Indirect Tensile Strength, Tensile Strength Ratio, and Wheel Tracking. The test results show that adding 1% of Rediset LQ-1106 resulted in the optimum performance of porous asphalt compared to other grade additions. This performance is evidenced by the increase in the mixture stability value by 18.62%, the Indirect Tensile Strength value of 20.14%, the dynamic stability value of 35.88%, and the most negligible deformation speed compared to porous asphalt, which does not use Rediset LQ-1106. However, the Index Retained Strength, and Tensile Strength Ratio tests did not significantly increase performance.</em></p> Eza Marizka Miftahul Fauziah Subarkah Copyright (c) 2022 Teknisia 2022-06-18 2022-06-18 27 1 12 23 10.20885/teknisia.vol27.iss1.art2 OPTIMALISASI PENGGUNAAN PASIR BESI SEBAGAI PENGGANTI AGREGAT HALUS DALAM CAMPURAN BETON MUTU TINGGI https://journal.uii.ac.id/teknisia/article/view/23820 <p><em>Infrastructure progress needs to be supported by the development of research on construction material technology, one of which is concrete technology. With its various advantages, concrete is continuously used to solve infrastructure problems. However, it also has impact on the use of large-scale materials and has the potential to deplete natural resources if not handled properly. One material that can be used as an alternative is iron sand. Iron sand is a mineral resource with magnesium content and has characteristics as a substitute for fine aggregate in concrete mixes. This study aimed to determine the effect of iron sand as a substitute for fine aggregate in high-strength concrete mixtures. This research method was a laboratory experiment by testing the characteristics of high strength concrete, namely compressive strength, tensile strength, and modulus of elasticity. This study found that the optimum concrete compressive strength occurred in the V-02 sample with a result of 51.71 MPa from the design compressive strength (fcr) = 45 MPa. The optimum tensile strength test occurred in the V-02 sample with a result of 4.13 MPa, and the optimum elasticity modulus test occurred in the V-02 sample producing 28684.37 MPa</em></p> Firjatullah Bangkit Aryoputro Mochammad Teguh Elvis Saputra Copyright (c) 2022 Teknisia 2022-06-18 2022-06-18 27 1 24 33 10.20885/teknisia.vol27.iss1.art3 EVALUASI STRUKTUR GEDUNG FAKULTAS HUKUM UNIVERSITAS ISLAM INDONESIA YOGYAKARTA BERDASARKAN PERCEPATAN GEMPA YANG DIHITUNG SECARA PROBABILISTIK https://journal.uii.ac.id/teknisia/article/view/22816 <p><em>Earthquake shocks generally cause the biggest shocks in building structures. Earthquake waves, generated by an earthquake event, are the main cause of this shaking. A new building of the Faculty of Law, Islamic University of Indonesia, was selected for this research to evaluate the effect of earthquake shaking on the structural response. A developed time history-based artificial earthquake ground motion was used in the structural analysis. Furthermore, the time history was developed based on spectral matching with target spectra derived from a probabilistic seismic hazard analysis. This analysis results in the building structure's seismic response, which is then evaluated based on the parameters set by the earthquake standards/regulations for buildings. This building is relatively safe against design earthquake shocks based on the results.</em></p> Wisnu Erlangga Lalu Makrup Malik Musthofa Suharyatmo Copyright (c) 2022 Teknisia 2022-06-18 2022-06-18 27 1 34 45 10.20885/teknisia.vol27.iss1.art4 EKSPLORASI REKAMAN GEMPA-GEMPA DI INDONESIA DAN KARAKTERISTIK DIRI YANG DINYATAKAN DALAM ACCELERATION BASED SEISMIC INTENSITY MEASURES (SIMs) https://journal.uii.ac.id/teknisia/article/view/23838 <p><em>Indonesia is a prone country to earthquake hazards. This situation is indicated by the number of earthquakes ranging from small to significant events. However, digital earthquake ground motion data are not available, making it difficult for further research. This paper aims to explore recordings of earthquakes that occurred in Indonesia, which are then presented in digital data and used to identify their damage potential in the form of Seismic Intensity Measures (SIMs). After being traced, it turned out that there were only six earthquakes whose ground acceleration time history was found through the paPers published by researchers. The earthquakes were the Mw 6.2 Yogyakarta (2006), the Mw7.6 Padang (2009), the Mw6.1 Bener Meriah Central Aceh (2013), and the Mw6.5 Pidie Jaya Aceh (2016), the Mw7.5 Palu (2018) and the Mw6.1 Malang (2021) earthquakes. The manual digitization and processing to obtain ground acceleration data every 0.01s time step are required. Eight aspects based on acceleration and two aspects based on response spectrum have been used as parameters for Seismic Intensity Measures SIMs. The exploration results show that the source of the earthquake in Sumatra is still relatively shallow, getting more profound in the Java and Nusa Tenggara subduction. The P.G.A. of the Yogyakarta earthquake is 0.272g with a total duration of more than 50 seconds. In general, according to SNI 1726, 2019, the spectrum has been able to cover all ground acceleration time histories. The Yogyakarta earthquake has the highest Earthquake Power, Arias Intensity, and Potential Destructiveness values, namely PE = 0.255 and IA = 2.201, and P.D. = 0.166.</em></p> Widodo Pawirodikromo Astriana Hardawati Copyright (c) 2022 Teknisia 2022-06-18 2022-06-18 27 1 46 59 10.20885/teknisia.vol27.iss1.art5 EVALUASI KARAKTERISTIK DAN KEBUTUHAN RUANG PARKIR SEPEDA MOTOR (STUDI KASUS PT TIRTA INVESTAMA WONOSOBO) https://journal.uii.ac.id/teknisia/article/view/20971 <p><em>Motorcycle parking facilities at PT Tirta Investama (TIV) Wonosobo are relatively new, but its application is felt less comfortable because it is too narrow. Moreover, some motorcycles are not parked in the places that have been provided but parked on the driveway and alleyway, which makes parking access even more limited. This research is aimed to evaluate motorcycle parking facilities. Data collection was carried out by direct survey at the PT TIV motorcycle parking location from 06.00 a.m. to 06.00 p.m. on Monday and Tuesday. The evaluation method compares the parking space needed (KRP) with the available Parking Space Unit (SRP). KRP was obtained from parking characteristics by Hobbs (1995) and Indonesian Technical Guidelines for The Implementation of Parking Facilities (1996). The evaluation showed that the parking space (SRP) was lacking because only 168 SRPs were available, but 223 SRPs were needed based on the analysis. In addition, the existing alleyway needs to be widened to comply with the regulations from the Directorate General of Land Transportation. This research also provides an additional design for motorcycle parking buildings that will be carried out according to the needs and available space, which is only sufficient for 206 SRP.</em></p> Grisela Nurinda Abdi Aisyah Nur Jannah Copyright (c) 2022 Teknisia 2022-06-18 2022-06-18 27 1 60 70 10.20885/teknisia.vol27.iss1.art6
