Abstract

Kalimantan Barat is characterized by peat and soft soils with low bearing capacity. Excessive loads on these soil types can cause significant soil subsidence, increasing the cracks risk in building structures. Alongside advancements in science and technology in the construction sector, sustainable building material innovations continue to be developed, one of which is using lightweight bricks as an alternative wall material. This study aims to evaluate the manufacturing method of lightweight bricks based on rice husk fibre and to analyze the effect of varying fly ash content on their physical and mechanical properties, referring to the SNI 8640:2018 standard. The fly ash compositions used were 0%, 35%, 40%, 45%, and 50%. Tests included visual inspection, bulk density, water absorption, sound and heat resistance, drying shrinkage, fire resistance, compressive strength, and tensile strength. The results show that adding fly ash significantly influences the brick"™s performance. The variation with 35% fly ash addition (Variation 2) demonstrated the most optimal performance, achieving the best balance between mechanical strength, thermal resistance, and physical characteristics by the SNI 8640:2018 standard. This study confirms that rice husk fibre lightweight bricks have the potential as an environmentally friendly alternative building material that meets technical standards.

Abstract

Rapid urbanization and population growth have led to a significant rise in the demand for building materials, thereby contributing to increased environmental impacts due to the widespread use of conventional materials such as concrete blocks and red bricks. These materials are known for their heavy weight and energy-intensive manufacturing processes, resulting in high carbon emissions and environmental degradation. In response to these concerns, this study explores an alternative in the form of rice husk lightweight bricks enhanced with gypsum casting as a partial cement substitute. The objective is to investigate the effects of gypsum casting on the physical and mechanical properties of the bricks and to evaluate their compliance with the Indonesian National Standard SNI 8640:2018 for lightweight wall bricks. Five variations of gypsum casting"”0%, 15%, 35%, 40%, and 45%"”were analyzed. Results show that bricks with 15% gypsum exhibited the best performance in terms of volume weight (998.438"“1.054.063 kg/m ³), compressive strength (4.326"“6.192 MPa), and fire resistance (up to 489.13 °C). All specimens displayed 0% drying shrinkage and acceptable levels of water absorption, sound resistance, and heat insulation, demonstrating the feasibility of using gypsum-modified rice husk bricks as sustainable building materials.

Abstract

The construction development in Indonesia increases the demand for building materials, including lightweight bricks as wall materials. Recent innovations utilize natural materials, such as rice husk, as an alternative mixture that is environmentally friendly and can reduce the volume weight of lightweight bricks. This research uses gypsum compound as a cement substitute binder in a mixture of rice husk lightweight bricks to analyze the effect of variations in the use of gypsum on the physical and mechanical properties of lightweight bricks, as well as to determine the ideal percentage of gypsum compound and cement reduction. The research method used is experimental, with the manufacture of test specimens for visual testing, volume weight, water absorption, sound resistance, heat resistance, drying shrinkage, compressive strength, and split tensile strength. The mix composition used a volume ratio of 1 cement: 3 rice husk, with gypsum substitution of 0%, 35%, 40%, 45%, and 50%. The results showed that adding gypsum to lightweight bricks can accelerate the hardening process but reduce its physical and mechanical performance, such as decreasing compressive strength and increasing water absorption. Therefore, this research does not recommend using gypsum compound to manufacture rice husk lightweight bricks.

Abstract

Water control technology aims to provide a sufficient water supply to avoid overflow. An automatic valve sluice gate made from fiberglass is preferred for water control in tidal agriculture. The mechanical valve sluice gate model can automatically release and close water discharge at a precise angle to optimize water control in tidal agriculture. The advantage of this sluice gate design is its utilization of the difference between upstream and downstream water levels on the sluice gate. A sluice gate design with a slope angle of 15 ° is recommended for tidal agriculture. The upstream water level should reach a height of 1.67 m for the sluice gate to open, while the downstream side should be at 0.82 m. The sluice gate will automatically open if the water level difference is 0.85 m in height and close if there is no water level difference. It is known that the flood level from the ground is 1 m to 2 m. It is suggested to elevate the land to prevent flooding for residents.

Abstract

A solid foundation is a concrete mix using steel reinforcement, but the reinforcement has the disadvantage of being corrosive when used in coastal areas. Therefore, this research uses strapping bands as a substitute for steel reinforcement. This research is focused on the manufacture of mortar plates for lightweight construction, especially in foundation parts such as footing foundations.   This research used 5 (five) variations of slab mixture including, variation A1 which is mortar slab without additional strapping band, variation B1 which is mortar slab with additional 3 pieces of strapping band as thick as 1 layer on each top and bottom layer, so on up to variation B4 as thick as 4 layers. The results of the mortar plate bending test obtained the value of the bending moment of variations A1, B1, B2, B3, and B4 are 0.148 kN.m; 0.183 kN.m; 0.222 kN.m; 0.278 kN.m; 0.325 kN.m. Then the maximum bending moment value is averaged in the variation that uses a 4-layer thick strapping band. From this research it can be concluded that to get a high bending moment value, the more strapping bands are used.

Abstract

Pervious concrete is one of the alternatives to prevent flooding during the rainy season. Because of the large number of pores produced by the absence or use of fine aggregate in its production, previous concrete has a poor compressive strength. This study focuses on the size and manner of compaction of coarse aggregates to boost the compressive strength of previous concrete. It is essential to address the void content in this process. The research started by analyzing the materials used to make the previous concrete mix. The next step was to determine the void content, plan the mix design, make the mix, treat the concrete, and finally test it using various methods such as volume weight, compressive strength, porosity, and permeability tests. Research shows that a three-layer perforated variation on a 0.5/0.5 cm coarse aggregate with a compressive strength of 21.04 MPa, volume weight of 1896.674 kg/m3, permeability of 0.597 cm/s, and porosity of 16.232% yields the best results. Although 24 MPa was the intended compressive strength, previous concrete fell short due to the paste content used in the compaction method. In addition, the volume weight is lighter than the plan, and the permeability and porosity are more significant than the plan. The relationship between aggregate size and compaction method is based on the graph of the effect of void content and paste content, which shows that the greater the paste content, the smaller the void content produced.

Abstract

Flood occurs when water overflows its banks due to inadequate channel capacity. Flooding typically results from too much precipitation, which prevents the channel from handling the water flow and results in a deluge. Pontianak City frequently faces severe and protracted flooding when it rains. Both high rainfall and rising sea levels, which impact the Kapuas River, might result in flooding. This argument states that this study was done to anticipate sea level rise for the next six years, which will impact Pontianak City's water flow height using tidal data from Pontianak's Climatology Maritime Station from 2016 to 2021. The average rate of sea level rise, calculated using the least squares approach, is 1.579 cm/year. With an increase rate of 0.017 cm/year, the average sea level rise forecast for the Kapuas River for the next six years is 1.789 cm. It will be necessary to reduce floods in the future to avoid the effects of water flow.

Abstract

As part of the city"™s economic growth, constructing hotels in Pontianak requires planning considering earthquake resistance to protect building occupants and minimize material damage and the negative economic impacts of earthquakes. Therefore, this study aims to apply the Intermediate Moment Resisting Frame (SRPMM) system to the structural design of a 7-story hotel building in Pontianak. In this study, the building structure is designed using reinforced concrete with the SRPMM system, which can provide adequate stability against earthquake loads. This research includes load calculations, structural analysis, earthquake resistance design, considering the planned structural dimensions, and using structural analysis software to calculate internal forces. The building is classified as KDS C. Thus, the application of SRPMM complies with the necessities set out in SNI 2847-2019 and SNI 1726-2019. The analysis results show that the designed structure meets earthquake opposition requirements according to established standards. This study contributes to developing the application of SRPMM to multi-story buildings, particularly in regions with low to moderate earthquake risks like Pontianak.
