Abstract

Slope instability is caused by several lithological and structural factors, slope geometry, relative relief, ground water, as well as changes in use and land cover. Mountainous areas, development and expansion of infrastructure networks can inadvertently cause natural slope shifts, thereby negatively impacting the stability of the excavated slope. Analysis of the geotechnical properties of soil and rock is important for understanding and predicting the possibility of landslides at certain locations. Geotechnical analysis is needed to carry out slope stability analysis which is carried out using GEO5 software. Construction of T/L 150 KV GI Kambang – GI Tapan, Tower TW. 203 with a tower structure at the top of the slope. Based on these conditions, a comprehensive study is needed to analyze the stability of natural slopes due to tower loads. Soil Type, Parameters c' and ?' (Drained), Parameters Cu and ? (Undrained) and soil properties index are based on CPT test results. The Bishop, Spencer, Janbu and Morgenstern-Price methods on natural slopes, tower loads, Natural with Tower+Pile Loads, Natural Slopes with Tower+Pile Loads, Earthquake Loads produce a safe condition against failure in Short-Term (Construction) and Long-Term conditions. Term (Operational). Analysis of the Fellenius method on natural slopes and tower loads in Short-Term (Construction) and Long-Term (Operational) conditions shows unsafe conditions. The safety factors resulting from the Bishop, Spencer, Janbu and Morgenstern-Price methods do not show significant differences in values.

Abstract

In construction projects, implementation requires heavy equipment to expedite all stages in process. The use of heavy equipment serves to shorten project implementation time and optimize a job. Therefore, the use of heavy equipment in construction projects is expected to accelerate expected work. The use of heavy equipment in construction projects is expected to facilitate existing work and heavy equipment to be used must be selected in an efficient and economical manner. A heavy equipment combination used in earthworks on the Moxy Hotel development project on Jl. Slamet Riyadi, Keprabon, Banjarsari District, Surakarta City is a Kobelco CAT 320D excavator, a Canter 120 Ps dump truck and a Jove JVR 180 D bore machine. The methods used in this research are survey methods and analytical methods. The survey method is used to determine number of heavy equipment in field, heavy equipment type while analytical method is used to determine time heavy equipment is used in the Moxy Hotel Development Project in Surakarta. After an analysis of variations in the duration of heavy equipment that is appropriate and can be used optimally is an alternative because it is more effective and efficient than the calculation of composition analysis and in the field, the time required is also more optimum. With an alternative composition of heavy equipment, namely 1 unit of excavator and 4 units of dump trucks for earthworks, and for foundation drilling work, 2 units of bore machines are needed.

Abstract

In the field of construction, particularly in geotechnical engineering, uncertainties in foundation design approaches are frequently encountered. Geotechnical uncertainties, especially in foundation design, pose complex challenges due to the heterogeneous nature of soil and data limitations. Dynamic load testing on pile foundations is an alternative method to static load testing in geotechnical engineering for evaluating pile capacity and behavior. The results of this analysis will be compared to the design capacity of pile foundations in the breasting dolphin structure. This study on a breasting dolphin structure utilizing Steel Pipe Pile (SPP) foundations with a diameter 610 mm. PDA tests were conducted on piles at points G6-23, G7-33, G7-38, and G8-46. The study begins with a literature review to comprehend methods and theories related to pile capacity analysis based on calendaring and PDA testing. Calendaring data were analyzed using empirical methods such as the Hiley Formula to estimate the dynamic bearing capacity of each pile. The pile capacity calculated using the Hiley Formula is generally higher than the results obtained from the Case Method and CAPWAP Analysis. The relationship between pile capacity based on the Hiley Formula (calendaring) and the Case Method (PDA test) yielded a linear regression equation of y = 1.0785x - 983.07 with R² = 0.2385, indicating a weak correlation. Meanwhile, the relationship between pile capacity from the Hiley Formula (calendaring) and CAPWAP Analysis (PDA test) resulted in a linear regression equation of y = -0.006x + 2909.8 with R² = 1×10?¹, indicating almost no linear correlation between the two.

Abstract

The rapid growth of the construction industry in Indonesia has led to a surge in cement production, a process that is energy-intensive and releases significant amounts of CO2. To mitigate the environmental impact of cement, geopolymer materials have emerged as a sustainable alternative. Given their role as spatial dividers, walls play a crucial role in a building's thermal and acoustic performance. Effective thermal performance can reduce the energy consumption required for air conditioning, while good acoustic performance enhances occupant comfort. This study compared the thermal and acoustic performance of lightweight concrete bricks (using cement as the primary material) with geopolymer bricks (utilizing fly ash). Two simulated rooms with distinct wall materials were constructed, and their temperature and acoustic properties were simultaneously measured. The thermal testing revealed that geopolymer bricks exhibited superior acoustic performance compared to lightweight bricks. Acoustic testing indicated that both brick types performed well acoustically. However, the acoustic performance of lightweight bricks peaked in hot weather, while geopolymer bricks demonstrated better acoustic performance at lower temperatures.

Abstract

This study aims to characterize the effect of superplasticizer addition on local aggregate concrete workability and early-age compressive strength. The methodology involved the use of Portland Composite Cement, local fine and coarse aggregates, and Fosroc Auracast SP310 superplasticizer at dosages of 1%, 1.6%, and 2%. Four concrete mix designs were prepared: normal concrete (BN) and concrete with superplasticizer additions (BN-1%, BN-1.6%, BN-2%). Slump and compressive strength tests were conducted according to Indonesian standards to assess workability and strength at 7 and 14 days. Results indicate that superplasticizer addition significantly improves concrete workability with slump values ranging from 560 to 630 mm compared to 115 mm for the control. Compressive strength also increased markedly, with BN-2% showing the highest strength at 38.56 MPa at 7 days and 51.94 MPa at 14 days. The study concludes that superplasticizer effectively enhances both workability and compressive strength without increasing water demand, resulting in denser and stronger concrete at early curing ages.
