Abstract

The utilization of eucalyptus bark waste as an alternative material in concrete represents an effort to reduce by-products from the forestry industry. However, the organic nature of this material may influence the mechanical performance of concrete. This study investigates the effect of alkali-treated eucalyptus bark waste used as a partial replacement for fine aggregate on the flexural strength of concrete. Prior to mixing, the bark waste was modified through alkaline treatment using a 1% NaOH solution for approximately 24 hours to improve its compatibility with the cement matrix. Replacement levels of 0%, 1%, 2.5%, and 5% by weight of fine aggregate were examined. Concrete beam specimens were tested for flexural strength at 28 days. The results indicate that increasing the proportion of eucalyptus bark waste leads to a reduction in flexural strength. The control mixture (0%) satisfies the flexural strength requirement of K250 concrete based on SNI T-15-1991-03, whereas mixtures containing eucalyptus bark waste fail to meet the minimum criterion. These findings suggest that alkali-treated eucalyptus bark waste is not suitable as a fine aggregate substitute in structural concrete.

Abstract

Cut and fill work is a critical initial stage in toll road construction, including the IKN Toll Road Project Section 1B spanning the Bandara Sepinggan – Balsam Toll segment. The effective use of heavy equipment is a key factor influencing the speed and quality of earthwork operations in this project. This study aims to analyze the productivity of excavators, dump trucks, and bulldozers, as well as determine the optimal number of heavy equipment units based on actual operational conditions in the field. A quantitative research method was employed by collecting primary data such as cycle time and equipment efficiency, along with secondary data including equipment capacity and production targets. The results indicate that excavators with bucket capacities of 0.93 m³ and 1.4 m³ have similar productivity levels of approximately 100 m³/hour, requiring nine units each. Dump trucks with capacities of 22 m³ and 10 m³ produce 32.73 m³/hour and 29.03 m³/hour, with required units of 26 and 30, respectively. The bulldozer shows a productivity of 93.2 m³/hour requiring five units. The findings highlight that productivity is influenced not only by equipment capacity but also by cycle time and operational efficiency. The study concludes that planning based on actual field data is crucial for determining the required heavy equipment efficiently and preventing resource inefficiencies.

Abstract

Bertambahnya volume penduduk untuk menyongsong IKN Nusantara selaras dengan bertambahnya kendaraan pribadi di Kota Balikpapan. Hal ini menyebabkan masalah pada bidang transportasi yaitu kemacetan di beberapa titik. Salah satunya terjadi pada simpang Jalan MT Haryono – Jalan Jenderal Sudirman (Simpang Beruang Madu). Masalah ini terjadi dikarenakan area jalan tersebut termasuk simpang utama di Kota Balikpapan yang pada jam berangkat kerja dan jam pulang kerja banyak pengendara yang melewati jalan tersebut sehingga membuat antrian kendaraan yang mengular. Penelitian ini bertujuan untuk mengevaluasi kinerja simpang pada kondisi eksisting, mengidentifikasi faktor-faktor apa saja yang mempengaruhi kinerja pada simpang dan memberikan solusi terkait permasalahan yang ada pada simpang tersebut. Penelitian ini menggunakan software PTV VISSIM (Student Version) dalam pemodelan simpangnya. Berdasarkan hasil penelitian menggunakan software PTV VISSIM pada Simpang Jl. MT Haryono – Jl. Jenderal Sudirman (Simpang Beruang Madu) dapat ditarik kesimpulan bahwa alternatif 3 (Pembatasan Kendaraan Yang Melintas) adalah yang paling sesuai dengan nilai Volume kendaraan yang diperbolehkan melintas pada Jl. MT Haryono (U) = 1165 smp, Jl. Jenderal Sudirman (T) = 1531, Jl. Jenderal Sudirman (B) = 2094 m, panjang Antrian (QL) : Jl. MT Haryono (U) = 28,08 m, Jl. Jenderal Sudirman (T) = 46,22 m, Jl.

Abstract

Arterial road Samarinda-Bontang often experiences flooding due to the accumulation of sediment in the channels, leading to a reduction in their capacity. This study aims to determine the erosion rate that will occur around the channels, the sedimentation rate that will occur in the channels, and to design the necessary dimensions for a control structure in the channels. The analysis and calculations were conducted using the Universal Soil Loss Equation (USLE) method to estimate the sedimentation volume for the next 10 years. The calculations were carried out using Microsoft Excel software, carefully following appropriate steps, resulting in the sedimentation volume figure used for the design of the control structure. From the analysis, it was found that the rainfall erosivity factor (R) is 13,588.02 Ton.mm/year, the soil erodibility factor (K) is 0.08, the length and slope factor (LS) is 3.68, and the Sediment Delivery Ratio (SDR), which represents the average proportion of sediment transported to the channel to the total erosion in the river basin, is 0.0941. These values yielded a potential erosion rate of 2,837.96 Ton/km²/year, an actual erosion rate of 1,557.002 Ton/km²/year, and a potential sedimentation rate of 146.5529 Ton/km²/year. Based on these values, the projected sedimentation volume in the channels over a 10-year period is 556.81 m³. Therefore, a control structure with dimensions of 20m in length, 2m in width, and 13.92m in depth, or alternatively 20m in length, 2m in width, and 1.39m in depth, is required for a planning period of 1 year.
