Abstract

With the advancement of technology and increasingly complex construction needs, the use of concrete has become essential in infrastructure development. One innovation to improve concrete quality is by adding supplementary or replacement materials. In Indonesia, iron powder is rarely utilized, leading to environmental pollution. This study uses iron powder to partially replace sand, aiming to address waste issues, and incorporates silica fume to partially replace cement. The mixing method replaces sand with 5%, 10%, 15%, 20%, and 25% iron powder and adds 10% silica fume relative to the cement amount in each iron powder variation. Results show that using iron powder and silica fume increases compressive and flexural strength at 5% and 10% iron powder with 10% silica fume. However, iron powder at 15%, 20%, and 25% with 10% silica fume led to reduced strength. Maximum compressive and flexural strength occurred at 10% iron powder with values of 27.55 MPa and 5.07 MPa, indicating that higher iron powder levels reduce compressive and flexural strength.

Abstract

The use of concrete materials in the world of construction has become the main choice because of its strength and durability. However, the use of concrete also has negative impacts on the environment, such as carbon dioxide emissions and the use of large amounts of energy. Therefore, using organic waste such as crab shells and oyster shells can help reduce waste and promote recycling practices.  In this research, a normal concrete compressive strength design of 25 MPa was used with the aim of research to obtain the effect of using crab shells and clam shells as a partial replacement for cement. The mixing method is carried out by partially replacing cement with crab shell powder and oyster shells as much as 4%, 8% and 12%, by carrying out compressive and tensile strength tests of the concrete. This research shows that partial replacement of cement with crab shells and clam shells for concrete as a whole causes a decrease in compressive and tensile strength. However, the use of oyster shells as a substitute for cement at an addition of 4% produces concrete compressive strength and split tensile strength that is slightly higher compared to normal concrete targets and the use of crab shells at the same percentage.

Abstract

Blackspots are locations on a road network that have a frequency of accidents or the number of traffic accidents per year that is greater than the specified minimum number of 30. With the effectiveness of efforts to handle accident-prone areas or Blackspots, it is hoped that accident cases will continue to decline from year to year and minimize the risk. Blackspots. The research was carried out on the Toboli - Poso section, Central Sulawesi Province, with the aim of determining the factors that cause Blackspots and how to alternatively handle Blackspots on this section. The research method used is a survey. The results obtained show that the causes of Blackspots are driver negligence in driving, vehicle factors, and the lack of adequate infrastructure on road sections that are prone to accidents, as well as road elements that are still not good and/complete. This triggers accidents that can result in fatalities such as serious injuries. Peak time for accidents often occurs at 12.00 - 18.00 WITA, the types of collisions are motor vehicles and pedestrians. Handling that can be carried out in Blackspot areas is by controlling traffic speeds, providing and/repairing road infrastructure and road elements in Blackspot areas, such as providing/adding zebra crossing traffic signs, traffic lights, noise tape, improving road shoulders, and others.

Abstract

Soil consists of relatively weak bonds between particles, often caused by carbonates, organic matter, or oxides that settle between the particles. As a construction foundation, soil sometimes does not meet the required specifications, such as clay, which has many limitations when used as a subgrade. Chemical additives can be used for soil reinforcement, such as Renolith and Fly Ash. In this study, each sample was substituted with 3% Renolith, along with Fly Ash additions of 10%, 15%, and 20%. For the California Bearing Ratio (CBR) test, three original soil samples were used, with an original CBR value of 25.38%. This value increased to 31.03% with the addition of 3% Renolith and 0% Fly Ash, showing that Renolith enhances CBR, with further increases seen with 3% Renolith plus 10%, 15%, and 20% Fly Ash. For permeability testing, one original soil sample was used, with each composition variation weighing 500 grams. The permeability coefficient of the original soil was 0.0017%, which increased to 0.0039% with 3% Renolith and 0% Fly Ash. This demonstrates that Renolith improves permeability, with further increases achieved by adding 3% Renolith plus 10%, 15%, and 20% Fly Ash. Using Renolith and Fly Ash can enhance the CBR and permeability coefficients, improving the load-bearing capacity of clay soil.

Abstract

Clay soil has low load-bearing capacity. One method to improve this issue is by mixing chemical additives, such as silica fume and red brick powder, into the clay soil as adhesive media that can fill the soil's pores, compacting and forming a solid mass. This study aims to determine the unconfined compressive strength and shear strength of clay soil after adding silica fume and red brick powder. The method involves testing unconfined compressive and shear strength using 9% red brick powder by soil weight, along with silica fume added in varying amounts of 5%, 10%, and 15%. Three samples are prepared for the original soil and each composition used. The unconfined compressive strength of the original soil increased by 48.2% with the addition of 9% red brick powder, while each 5% addition of silica fume raised the compressive strength by an average of 3.1%. Similarly, shear strength increased by 33.5% in the original soil with 9% red brick powder, while each 5% silica fume addition improved it by an average of 5.4%. The addition of red brick powder and silica fume can effectively increase the compressive and shear strength of clay soil.

Abstract

Soil improvement is needed to increase the soil's load-bearing capacity, one method being chemical stabilization using materials like gypsum and lime. Gypsum enhances soil stability due to its calcium content, which binds soil particles and reduces cracking. Lime strengthens the soil and reduces settlement by forming hydrates and minimizing capillary absorption. The goal of soil improvement is to bind and consolidate aggregate materials within the soil. Therefore, soil improvement using gypsum and lime is necessary for enhanced load-bearing capacity. In this study, CBR (California Bearing Ratio) and permeability tests were conducted with a gypsum substitution of 8% in each sample, and lime added at 15%, 20%, and 25%. The CBR and permeability values increased progressively. The original soil's CBR value was 16.15%, while soil mixed with gypsum showed values of 22.19%, 33.95%, 46.79%, and 53.06%, with a maximum increase of 53.00%. For permeability, the original soil had a rate of 0.0034%, and soil mixed with gypsum and lime showed rates of 0.0048%, 0.0057%, 0.0066%, and 0.0085%, with a maximum increase of 0.4117%.

Abstract

Clay soil has weak particle bonding and low load-bearing capacity, making it less suitable as a subgrade material in construction. One method to address this issue is stabilization by adding renolith and Fly Ash to the clay soil as stabilizing agents that can bind and fill the soil’s pores. This study aims to evaluate the impact of renolith and Fly Ash on clay soil by testing its unconfined compressive strength and shear strength. The method used involved adding 6% renolith to each sample, with Fly Ash varied at 20%, 25%, and 30%. Mixing was done at the optimum moisture content, obtained from compaction tests. Three samples were prepared for each composition. The unconfined compressive strength of the original soil was 0.597 kg/cm², which increased with the addition of renolith and Fly Ash to 0.637 kg/cm², 0.663 kg/cm², 0.792 kg/cm², and 1.011 kg/cm². The original soil’s shear strength was 0.5835 kg/cm², which rose to 0.6428 kg/cm², 0.9398 kg/cm², 1.0285 kg/cm², and 1.2522 kg/cm² with renolith and Fly Ash. Thus, renolith and Fly Ash effectively enhance the unconfined compressive and shear strength of clay soil.

Abstract

The structural engineering field is advancing rapidly. Fly Ash contains silica, similar to cement. This study examines the use of Fly Ash waste as a cement substitute in concrete production, with polycarboxylate added. Fly Ash was used at 15% and 30% with polycarboxylate at 1% and 2%. The target compressive strength was 25 MPa, with normal concrete mix. Tests focused on compressive strength in polycarboxylate variations. Another set of concrete mixes substituted 15% and 30% cement with Fly Ash, adding polycarboxylate at 1% and 2% of cement content. Results showed a compressive strength of 25.38 MPa for normal concrete and 25.78 MPa and 25.94 MPa for 1% and 2% polycarboxylate mixes, respectively. With 15% and 30% Fly Ash plus 1% polycarboxylate, compressive strength increased by an average of 0.635 MPa; with 2% polycarboxylate, it averaged 5.25 MPa. Similarly, for tensile strength, 1% polycarboxylate with 15% and 30% Fly Ash achieved an average of 5.45 MPa, while 2% polycarboxylate reached 18.63 MPa with the same Fly Ash percentages.

Abstract

The low performance ethos displayed by employees of the Sultan Hassandin Makassar International Airport Development Project is of course related to the leadership implemented by the leader. Because leadership is an activity that influences and directs the behavior of subordinates or other people to achieve organizational or group goals. Apart from that, the work environment at the Sultan Hassandin Makassar International Airport Development Project is not good, there are still employees who appear relaxed during working hours, and there are also employees who chat with colleagues during working hours. Moreover, work discipline at the Sultan Hassandin Makassar International Airport Project Construction which is not conducive to work discipline can cause employee performance to be less than optimal. The quality of the work environment, work discipline and leadership of construction companies can have a significant and positive influence on employee performance at the Bandar Sultan Hasanuddin Makassar Development Project with an influence value on work environment variables of 0.483, leadership variables of 0.352, and work discipline of 0.454. Where in this research the work environment variable is the variable that has the greatest influence on employee performance in the construction of the southern terminal of Sultan Hasanuddin Makassar International Airport.
