Abstract

Concrete is a widely used construction material, but its production has a negative impact on the environment. This study aims to determine the effect and optimal percentage of using palm kernel shells and coconut fiber in concrete mixtures on the compressive strength of concrete. The research method involved making a variety of concrete mixes with the replacement of conventional aggregates by palm kernel shells as coarse aggregate and coconut fiber as fine aggregate. Four mix variations were tested: A (1% coconut fiber, 5% palm kernel shell), B (2% coconut fiber, 5% palm kernel shell), C (1% coconut fiber, 10% palm kernel shell), and D (2% coconut fiber, 10% palm kernel shell). Compressive strength testing was conducted at 7, 14, and 28 days of concrete age. The analysis showed that variation A, with 1% coir and 5% palm kernel shell, produced the closest compressive strength to normal concrete. ANOVA tests confirmed the significant effect of these mixtures on compressive strength. The contribution of this research lies in the development of alternative concrete materials that are more environmentally friendly, utilizing agricultural waste to reduce dependence on natural resources and lower the carbon footprint of the construction industry.

Abstract

Indonesia is a country with a high risk of natural disasters, due to its position between major tectonic plates and in the Pacific Ring of Fire. This condition makes Indonesia prone to disasters. However, the low level of student understanding of disaster response measures shows the importance of disaster education from an early age. This community service activity aims to improve the understanding and preparedness of SMKN 1 Ketapang students in facing disasters through socialization and simulation of disaster management. The activity method consists of socializing disaster material with the help of visual aids and direct simulations guided by the BPBD team. Through the stages of preparation, socialization, and simulation, students were given an in-depth understanding of the types of disasters, evacuation techniques, and the use of light fire extinguishers (APAR). The evaluation results showed a significant increase in understanding from 30% to 80% after this activity was implemented. This increase shows that disaster education involving theory and practice is effective in building students' awareness and preparedness. This program is expected to be continued regularly to build a culture of disaster preparedness among school students.

Abstract

In Ketapang District, there is potential to reduce the environmental impact of concrete production by utilizing local agricultural waste. This study aims to determine the comparison between the physical properties of coconut fiber and palm kernel shells as aggregate substitutes in concrete, with the physical properties of conventional aggregates such as sand and crushed stone. Coconut coir came from tourism waste in Ketapang Regency, while palm kernel shells were taken from the waste of the local palm oil processing industry. Laboratory tests were conducted to compare the physical properties of coconut fiber and palm kernel shell with conventional aggregates, namely sand and crushed stone. The test results showed significant differences. Coconut husk had a specific gravity of 1.19 and palm kernel shell 1.59, compared to sand 2.09 and crushed stone 2.81. The moisture content of palm kernel shell (17.40%) was much higher than that of crushed stone (1.15%), while the water absorption of palm kernel shell reached 37.16%, far above the water absorption of crushed stone (4.05%). Coconut husk and palm kernel shell have lower specific gravity than conventional aggregates, making them ideal for lightweight concrete. However, the high water absorption of palm kernel shells requires adjustments to the concrete mix design. This study shows that the use of local waste materials can contribute to the development of environmentally friendly concrete, but careful composition control is required to maintain concrete performance. Keyword: aggregate, concrete, material testing.

Abstract

This study aims to assess the effect of using Fly Ash and Rice Husk Ash as cement substitutes in the manufacture of environmentally friendly concrete. Fly Ash, a waste from coal-fired power plants, and Rice Husk Ash, an agricultural waste, were used as partial cement substitutes in four concrete mix variations, viz: normal concrete without substitution (N), concrete with 20% Fly Ash (K), concrete with a combination of 10% Fly Ash and 10% Rice Husk Ash (L), and concrete with 20% Rice Husk Ash (M). The compressive strength test was conducted at the age of 7 days, 14 days, and 28 days. The results showed that concrete with 20% Fly Ash (K) produced the most optimal compressive strength, especially at longer concrete ages. Concrete with Rice Husk Ash substitution (M) and a combination of Fly Ash and Rice Husk Ash (L) showed lower compressive strength than normal concrete (N) and Fly Ash alone. Therefore, the use of Fly Ash at 20% gave the best compressive strength results among the variations tested.

Abstract

This study was conducted to evaluate the potential of bottom ash as a fine aggregate substitute in K-175 concrete and determine the optimum percentage that produces the best compressive strength. Mining of sand as fine aggregate for concrete has caused environmental damage, so an alternative material that is more environmentally friendly is needed. Bottom ash, a solid waste from coal combustion in PLTU, has physical and chemical characteristics that support its use in concrete mixtures. This study used variations of bottom ash substitution of 5%, 12.5%, and 17.5% of the total weight of fine aggregate. Compressive strength tests were conducted at 7, 14, and 28 days of concrete age. The results showed that 5% bottom ash substitution produced the most optimal concrete compressive strength, equivalent to normal concrete at an estimated age of 28 days at 186.86 kg/cm². Meanwhile, 12.5% and 17.5% substitution showed a significant decrease in compressive strength compared to normal concrete. The physical characteristics of bottom ash, such as higher content weight and coarse texture, contribute positively to mechanical bonding in concrete. However, the high silt content of bottom ash requires further treatment to improve its quality. This research is in line with previous studies supporting the utilization of industrial waste in concrete construction, but provides a new focus on K-175 grade concrete for lightweight construction applications. In conclusion, bottom ash can be used as an alternative fine aggregate in concrete, with an optimal substitution of 5%. The utilization of bottom ash not only supports environmental sustainability, but also offers an innovative solution for industrial waste management in construction. Keyword: bottom ash, fine aggregate, industrial waste.

Abstract

The use of organic waste as a substitute material in concrete mixtures is one of the efforts to reduce environmental impacts and optimize the utilization of existing natural resources. Coconut fiber, as one of the abundant agricultural wastes, has the potential to be used as an aggregate substitute in concrete. This study aims to analyze the effect of coconut fiber addition on the compressive strength of K-175 grade concrete. Coconut fiber was used as a partial replacement for coarse aggregate with variations of 0%, 0.3%, 0.5%, and 0.8%. Concrete was tested at 7, 14, and 28 days to measure the compressive strength produced at each test age. The results showed that the control concrete (without coconut fiber) produced the highest compressive strength at all test ages. The addition of coir caused a decrease in compressive strength, especially at 7 days, which was due to the interaction between coir and cement matrix which was not optimal at the initial stage of hydration. However, at 28 days, the concrete with coir addition showed an increase in compressive strength although it was not significant compared to the control concrete. The optimum level of coir that does not significantly reduce the concrete quality is about 0.3%. Despite the reduction in compressive strength, the concrete produced at this level still meets the strength standards required for lightweight concrete applications or concrete with medium strength specifications. This study suggests that coir can be considered as an alternative aggregate replacement material in the production of environmentally friendly concrete, with appropriate proportion adjustments to optimize concrete performance.

Abstract

Plastic waste, especially HDPE, has a very long decomposition time and has the potential to pollute the environment. Therefore, this study aims to determine the effect and most optimal variation of the addition of plastic bottle waste on the compressive strength of K-175 quality concrete. The experimental method was used by testing materials and compressive strength of concrete at the Ketapang State Polytechnic Laboratory from May to August 2024. The test results showed that the average compressive strength of normal concrete based on conversion to 28-day age reached 176.37 kg/cm², while the compressive strength of concrete with HDPE variations decreased with values ranging from 124.95 kg/cm² to 152.60 kg/cm². Of the various variations tested, the mixture with 0.75% HDPE showed the best compressive strength results compared to other variations, with an average compressive strength based on conversion to 28 days of age of 152.60 kg/cm².

Abstract

The quality of water used in concrete mixes, especially the Total Dissolved Solids (TDS) content, is often ignored despite its significant effect on the compressive strength of concrete. Normal, sea, and swamp water have different TDS characteristics, where sea water tends to have higher TDS. This study aims to analyze the relationship between the TDS value of water and the compressive strength of concrete at 7 and 28 days and identify significant differences in the compressive strength of concrete using normal, sea, and swamp water. The method used was experimental research, with samples consisting of 3 categories of water (normal, sea, and swamp) and 3 samples per category. TDS values were measured using a TDS meter, while concrete compressive strength was tested with a digital press. The research was conducted through four stages: water sampling, concrete mix preparation, molding of test specimens, and compressive strength testing. Linear regression analysis showed that the higher the TDS value, the lower the concrete compressive strength at 7 and 28 days. In addition, the ANOVA test revealed significant differences in the compressive strength of concrete at 7 days among the three types of water. These findings indicate the importance of paying attention to water quality in concrete mixes to produce optimum quality concrete. Keyword: concrete compressive strength, sea water, swamp water, TDS.
