Abstract

On Agricultural Road Mekar Sari Village, Benua Kayong District, Ketapang Regency, West Kalimantan there are still roads that are separated by the flow of the river where the roads can be used by farmers in bringing their agricultural products to their destination, therefore the construction of bridges must be carried out at that location. At this time the planner used a type of concrete floor wooden bridge that was in accordance with the needs in the field. The objectives to be achieved are to make a plan drawing and calculate the budget required for the construction of a bridge on Road Agriculture. To obtain the data in this study, researchers used field observations and data collection for the 2021 Ketapang Regency material unit price list from PUPR to make the RAB. After making the plan drawings and analyzing the RAB calculation, the total cost needed for the construction of the bridge on Road Agriculture, Mekar Sari Village, is Rp. 31.357.000

Abstract

Permasalahan transportasi di kota-kota besar di Indonesia khususnya di Jalan R. Suprapto Kabupaten Ketapang semakin meningkat dari waktu ke waktu sejalan dengan pertumbuhan populasi, pesatnya tingkat pertumbuhan jumlah kendaraan dan kepemilikan kendaraan, urbanisasi serta sistem angkutan umum yang kurang efisien. Hal ini berdampak pada turunnya tingkat kinerja ruas jalan, termasuk perilaku gerak U-Turn pada bukaan median jalan. Penelitian ini bertujuan untuk mengetahui karakteristik lalu lintas, kapasitas jalan, tingkat pelayanan jalan (LOS), waktu rata-rata kendaraan melakukan U-Turn, panjang antrian dan alternatif yang akan di terapkan pada penelitian ini berdasarkan pedoman MKJI 1997. Dari hasil penelitian dan pembahasan di Jalan R. Suprapto didapatkan nilai karakteristik arus lalu lintas yang terdiri dari volume lalu lintas pada jam sibuk dari arah Jl. R. Suprapto – Jl. Gatot Subroto sebesar 513,8 smp/jam dan untuk arah Jl. Gatot Subroto – Jl. R. Suprapto sebesar 651,35 smp/jam. Kecepatan kendaraan sebesar 49,86 km/jam. Kerapatan lalu lintas untuk arah Jl. R. Suprapto – Jl. Gatot Subroto sebesar 10,24 smp/km dan untuk arah Jl. Gatot Subroto – Jl. R. Suprapto 13,1 smp/km. Kapasitas ruas jalan sebesar 5.422,3 smp/jam. Nilai tingkat pelayanan jalan didapat nilai A

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

In a construction project, roof tiles and ceramics that are cracked (broken) are often thrown away as construction waste. Apart from that, house demolition activities also produce roof tile and ceramic shards that are not reused. No one has conducted research where this wastes is used as a substitute for cement. This research aims to determine the effect of roof tile and ceramic fragments as a substitute for cement on the compressive strength value of concrete. Experimental methods were used in this research. Observations were carried out at the structure and materials laboratory, Ketapang State Polytechnic. The results of the research show that the effect of using tile and ceramic fragments as a substitute for cement with varying percentages of 5% tile, 5% ceramic, 5% tile and ceramic, and 10% tile and ceramic in concrete has an effect on the compressive strength value. The greater the percentage of tile and ceramic fragments used in the concrete mixture, the more the compressive strength value of the concrete will decrease. The average compressive strength of concrete at 7 days between normal concrete and concrete with varing percentages of 5% tile, 5% ceramic, 5% tile and ceramic, and 10% tile and ceramic has a comparative value of 12.76 M.Pa, 12.03 MPa, 12.16 MPa, and 11.03 MPa. The average estimated compressive strength of concrete aged 28 days has comparative values of 19.00 MPa, 18.51 MPa, 18.71 MPa, 17.43 MPa, and 16.97 MPa.

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.

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.
