Abstract

The utilization of waste from wood cuttings is uncommon, and one of the wastes that is rarely employed is the leftovers of galam wood or galam powder cuttings. On this basis, a study entitled "The Effect of Adding Galam Powder as a Substitute for Fine Aggregate in Normal Quality Concrete Mixtures" was carried out. In this study, the experimental approach was used as the research method. The percentage of galam powder waste in fine aggregate, which can range from 0% to 30%, is the independent variable in this study. Other aggregates, such as cement, fine aggregate, coarse aggregate, and water, are the study's dependent variables. The compressive strength of 28-day-old material in the normal combination has a compressive strength of 22.23 MPa, the V10 mixture has a compressive strength of 4.58 MPa, the V20 mixture has a compressive strength of 3.11 MPa, and the V30 mixture has a compressive strength of 1.41 MPa. Based on the findings, it can be concluded that using waste galam powder as a fine aggregate alternative has not been successful since the galam powder does not bind completely to the concrete

Abstract

The pile built on soft soil has a tendency to fail its submission (bearing failure). This is caused by soft soils to have a low carrying capacity to carry the burden of construction. If a pile must be built which must be completed in a relatively fast time and must be stockpiled on soft soil, can be overcome by reinforcing the soil using geogrid material so as to increase the carrying capacity of soft soil (bearing capacity) and stability of the pile. Analysis uses the element method to the help of plaxis software to find the value of safety, deformation, and voltage changes in the pile built on the soft soil strengthened by geogrid. From this study it was found that the Modeling Piles 2 without Geogrid got a SF 1,0668 value and using Geogrid got a SF 1,3349 value. The safety factor of the pile of land 2 is above 1.25 which means that landslides are rare even without geogrid or use geogrid.

Abstract

Bundaran Kayutangi merupakan salah satu bundaran penting di Kota Banjarmasin yang memiliki empat lengan dan melayani arus lalu lintas dari berbagai arah, yaitu arus lalu lintas yang berasal dari Jl. Adhiyaksa, Jl. Perdagangan, Jl. Brigjend Hasan Basri dan arah Barito Kuala. Tingginya volume lalu lintas yang melewati bundaran menyebabkan terjadinya hambatan atau pertemuan kendaraan yang cukup padat dari berbagai arah jalan. Untuk menanggulangi kemacetan yang terjadi, pemerintah melakukan upaya dengan menutup satu lengan simpangan pada arah Kayutangi ujung. Diharapkan dengan adanya penutupan satu lengan ini dapat mengurangi kemacetan dan memperlancar arus lalu lintas di bundaran. Penelitian ini bertujuan untuk mengetahui bagaimana kinerja bundaran Kayutangi setelah dilakukan penutupan pada salah satu lengan. Selain itu, untuk mengetahui kemampuan bundaran dalam melayani arus lalu lintas pada 4 tahun yang akan datang. Metode analisis yang digunakan pada penelitian ini adalah metode MKJI 1997. Data yang digunakan adalah data primer dan sekunder. Data primer yang diperlukan adalah ukuran geometrik bundaran dan data lalu lintas harian rata-rata. Pengumpulan data dilakukan selama 3 hari dari pukul 06.00 – 18.00 WITA. Dari hasil analisis data, didapatkan Tingkat Pelayanan Bundaran Kayutangi Kota Banjarmasin yaitu D yang artinya lalu lintas bertambah, hambatan dan tundaan menjadi meningkat. Berdasarkan hasil tersebut perlu dilakukan penanganan agar tingkat pelayanan bundaran tidak memburuk tiap tahunnya.

Abstract

The Trikora Road section at Km 2–Km 4 in Banjarbaru City is one of the locations with a high rate of traffic accidents, making a road functional feasibility assessment necessary to evaluate road conditions and identify factors contributing to non-compliance with technical standards. This study aims to assess road functional feasibility based on the Regulation of the Minister of Public Works Number 11/PRT/M/2010 concerning Procedures and Requirements for Road Functional Feasibility. The research method was conducted through a field survey by comparing existing road conditions with technical standards for each road component and subcomponent, which were then classified into functional feasibility categories. The results indicate that 42.86% of the Trikora Road section falls into the Conditional Functional Feasibility (***) category, indicating that some technical requirements have been fulfilled and the road is still able to provide safety for road users. In addition, 42.86% of the section is categorized as Downgraded Functional Feasibility (**), indicating that several road components do not meet technical standards and require improvement. Meanwhile, the functional feasibility assessment of road facilities directly related to road users shows a Not Functionally Feasible (T) category of 14.29%, indicating the need for immediate corrective actions. The recommended improvements focus on enhancing road facilities and improving traffic management to reduce accident risk and increase road user safety and comfort.
