Abstract

Asphalt concrete is a combination of continuous aggregate gradation with hard asphalt binder (DPUPR, 2014). Asphalt concrete is a combination of aggregate, and asphalt, with or without additives. Latex and coconut shell charcoal ash was chosen as additives because they are abundantly available and easy to obtain. This study used a latex percentage of 1%; 2%; and 3%, as well as filler from coconut shell charcoal of 1%; 1.5%, and 2%. The aim of the study was to obtain the effect of the substitution of latex (rubber sap) and filler from coconut shell charcoal on the performance characteristics of asphalt concrete (laston). Material testing methods and marshall testing are guided by Bina Marga 2018. To get the optimum asphalt content (KAO) it is tested with three variations of the percentage of asphalt content and is obtained at 5%. This value is then used for Marshall stability testing with additives. The test results show that the substitution of latex and coconut shell charcoal filler can increase the value of marshal stability and flexibility of the mixture at 3% latex and charcoal ash content. These results are in accordance with the characteristics of the lastton in the 2018 Bina Marga Specifications. ABSTRAK Aspal beton merupakan gabungan gradasi agregat menerus dengan bahan pengikat aspal keras (DPUPR, 2014). Aspal beton merupakan gabungan dari agregat, aspal, dengan atau tanpa bahan tambahan. Lateks dan abu arang tempurung kelapa dipilih sebagai bahan aditif karena melimpah ketersediaan dan mudah didapat. Penelitian ini menggunakan prosentase lateks sebesar 1%; 2%; dan 3%, serta filler dari arang tempurung kelapa sebesar 1%; 1,5%, dan 2%. Tujuan Penelitian untuk mendapatkan pengaruh substitusi lateks (getah karet) dan filler dari arang tempurung kelapa terhadap kinerja karakteristik aspal beton (laston). Metode pengujian material dan pengujian marshall berpedoman pada Bina Marga 2018. Untuk mendapatkan kadar aspal optimum (KAO) diujikan dengan tiga variasi prosentase kadar aspal dan di dapatkan sebesar 5%. Nilai ini selanjutnya digunakan pengujian stabilitas marshall dengan bahan aditif. Hasil pengujian menunjukkan bahwa substitusi lateks dan filler arang tempurung kelapa dapat menambah nilai stabilitas marshal dan fleksibilitas campuran pada kadar lateks dan abu arang 3%. Hasil tersebut sesuai dengan karakteristik laston dalam Spesifikasi Bina Marga 2018.

Abstract

Penggunaan karet ban bekas (Crumb Rubber) sebagai bahan tambah merupakan salah satu alternative untuk mengurangi penggunaan bahan aspal disamping mengurangi pencemaran lingkungan. Hadiwiyono (2012), meneliti pengaruh penambahan parutan ban karet terhadap marshall. Prosentase kadar aspal yang digunakan 7% sampai 9% aspal yang dicampur dengan 20%, 21% dan 22% serbuk karet ban bekas. Dari hasil uji stabilitas marshal didapatkan nilai optimun penetrasi dan daktilitas pada kadar aspal 7% dengan serbuk ban 22%, hasil uji penetrasi menunjukan angka rata-rata 65 memenuhi persyaratan SNI 06-2456-1991) dan nilai daktilitas rata-rata 68,1, nilai ini tidak memenuhi persyaratan SNI 2432-2011 (≥100 cm). Berdasarkan hal diatas didapatkan hasil bahwa penambahan CR mempunyai pengaruh yang dapat meningkatkan nilai Volumetrik dan Marshall . Hasi penelitian ini ini dilanjutkan dengan kadar CR yang berbeda, dan didapatkan hasil terbesar dari test volumetrik didapatkan nilai MQ 497,3 kg/mm pada varian nomor 11 dengan kadar aspal 5,8% dan CR 4%, nilai VIM 3,13% pada varian nomor 11 dengan kadar aspal 5,8% dan CR 4% dan nilai VMA 19,42% pada varian nomor 8 dengan kadar aspal 5,8% dan CR 3%. Dan untuk nilai terbesar test marshall didapatkan nilai stabilitas 1180,80 kg pada varian nomor 8 dengan kadar aspal 5,8% dan CR 3%, nilai flow 2,69 mm .Varian tersebut telah memenuhi spesifikasi SNI Bina Marga 2010 Rev 3 untuk lalu lintas sedang.

Abstract

Traffic signs are divided into conventional signs and electronic signs. The message conveyed is in the form of a pigtogram and/or electronic message. (Budiati, 2014) compared the legibility distance of letter dimensions on conventional signs, it was found that H=1.032+0.273D with H being the height of the letter and D being the reading distance. (Budiati, 2023), examined the relationship between the driver's reading speed and the number of words and lines in the Variable Message Sigh. This research produces a reading speed of 1.37 words/second. The research was continued to obtain a modeling of the readability distance for conventional and electronic word message signs with the dependent variable (Y) reading distance. Data on reading distance and reading time in the field were analyzed using the SPSS v.23 approach, and the obtained was Y= 2.990 (X1) + 0.009(X2) + 0.001(X3) for conventional signs Y = 3.557 (X1) + 0.440 (X2) + 0.004 (X3), while Based on collineatity the modeling value of reading distance (2) versus reading distance 1 is as follows: Y = 5.463 + 0.513 (X1) + 0.10 (X2) + 0.009 (X3) + 0.004.

Abstract

This design hospital building is planned to be built in the city of Palu. Palu City has high earthquake potential, has history of liquefaction, tsunami and landslides disasters. Thorough design is needed so that this hospital building still become a place for health services after a disaster occurs. The building was designed using the Special Moment Resisting Frame Structure system based on the SNI. Earthquake load analysis uses the response spectrum method based on Earthquake Resistance Planning Procedures (SNI 1726:2019). This concept obtains structure design that meets SNI and still strong in strong earthquake and liquefaction. Analysis has been carried out and it was found that the potential for liquefaction to occur at a depth of 1.5 M to 4.5 M so that the foundation chosen was 4 piles with a diameter of 40 cm, a depth of 6 meters per pile cap. From the results of calculations, it shows that the structure of the emergency room building at CT Arsa Palu Hospital is safe from an analytical perspective.

Abstract

Marine concrete is used for structures in marine environments that are susceptible to chemical attacks such as sulfates and chlorides. This study aims to analyze the effect of adding 7% silica fume on the compressive strength of marine concrete soaked in seawater. The experimental research method was carried out by making 12 concrete cylinder samples (diameter 15 cm × height 30 cm), consisting of two variations: concrete without silica fume and concrete with 7% silica fume. Compressive strength testing refers to SNI 03-1974-1990 and ASTM C39, with seawater immersion for 50 days and testing at the ages of 14, 28 and 50 days. The results showed that concrete with 7% silica fume achieved an average compressive strength of 39.90 MPa at the age of 28 days, higher than concrete without silica fume (37.64 MPa). This increase is due to the pozzolanic reaction of silica fume which fills the pores of the concrete and forms calcium silicate hydrate (CSH) compounds, increasing the density of the concrete matrix. The slump value of both concrete variations is stable at 12 cm, meeting the planned workability criteria. This study states that the addition of 7% silica fume is effective in increasing the compressive strength and resistance of marine concrete to the marine environment. Recommendations include the use of silica fume for marine structures, strict supervision in mixing materials, and optimization of mixing time to prevent too fast setting time. This study contributes to the development of environmentally friendly concrete with high durability in coastal areas.

Abstract

The use of additives originating from nature in the form of latex (rubber latex) and charcoal ash from coconut shells is expected to be a solution in improving the quality of road pavement. Latex (rubber latex) substitution of 1%, 2% and 3% and charcoal ash of 1%; 1.5%; and 2% were used in this research, with the aim of determining the effect of additives on asphalt properties values based on the 2018 Bina Marga Specifications. In the penetration test there was a decrease with an optimum substitution of 59.1 at a proportion of 2% latex and 1.5% charcoal ash. . In flash point and burn point tests, the addition of latex and charcoal ash caused the asphalt to heat up more quickly at lower temperatures than asphalt without additional ingredients. In testing the flash point and burning point, the optimum substitution was 1% latex and 1.5% charcoal ash. Meanwhile, in the ductility test, with the substitution of 1% latex and 1.5% charcoal ash, a ductility value of 105 mm was obtained. From several tests, it was concluded that the optimum substitution was for the 2% latex variant and 1.5% charcoal ash. These results meet the 2018 Bina Marga Specifications
