Abstract

Nowadays, the presence of plastic waste is increasing. This is because the use of plastic as a material for packaging food and drinks has not yet been replaced. This is why researchers are concerned about the accumulation of polyethylene terephthalate (PET) plastic waste at the location of road construction projects which originates from workers' daily consumption of food and drinks. So it is felt necessary to use PET plastic waste as an additional or substitute material for asphalt mixtures that is environmentally friendly and economical, because PET plastic contains polymers that are plastomers. In this research, various levels of PET plastic waste were used: 0%, 4%, 4.5%, 5%, 5.5%, 6%. The research results concluded that the use of 4.5% PET plastic waste in the AC-BC mixture had marshall characteristic values ??that requirements. The optimum asphalt content value is 5.7% with Marshall properties including a stability value of 1,235.1 Kg, a flow value of 3.03 mm, 409.41 Kg/mm of Marshall Qoutient (MQ) value, 15, 62% of VMA, 72.19% of VFA, and 4.34% of VIM.

Abstract

Coal fly ash has been categorized as factory waste therefore We should reduce factory waste and utilize it wisely optimal. In this research, coal fly ash and ash were used stone as an alternative to filler in AC-WC mixtures. The purpose of this research is to determine the marshall characteristics of the AC-WC layer with using a combination of coal fly ash and rock ash fillers. Research methods used in this research was an experimental method of varying the levels of coal fly ash filler and rock ash combined, namely 0%- 100%, 50%-50%, 60%-40%, 70%-30%, 80%-20%, 90%-10%, and 100%-0%.The specifications used in this research are General Bina Marga Specifications 2018 Revision 2. The optimum asphalt content obtained was 5.9%. Based on the results of Marshall testing variations of coal fly ash and stone ash fillers The best in this research was the variation of 50% coal fly ash and 50% rock ash. This is shown based on the stability value the composition obtains The stability value is 1,976.10 kg and the MQ value is 640.89 kg/mm with The melting value is 3.08 mm so it can be concluded that the quality of the AC-WC is the best In this research there are filler variations of 50% coal fly ash and 50% rock ash.

Abstract

Pada umumnya, pondasi sebagai elemen struktur bawah terbagi menjadi dua jenis utama, yaitu pondasi dangkal dan pondasi dalam. Pondasi berfungsi sebagai elemen struktur bawah yang menyalurkan beban dari struktur atas ke lapisan tanah keras. Untuk mencegah terjadinya kegagalan struktur, diperlukan investigasi tanah terlebih dahulu guna memahami jenis dan karakteristik tanah sebelum menentukan jenis pondasi yang akan digunakan. Penelitian ini bertujuan untuk menganalisis perbandingan daya dukung pondasi tiang pancang mini (minipile) pada proyek pembangunan rumah tinggal dua lantai menggunakan metode empiris dan metode statis dengan alat Hydraulic Static Pile Driver (HSPD). Penyelidikan tanah dilakukan menggunakan uji Cone Penetration Test (CPT) atau sondir di tiga titik pengujian untuk mendapatkan data karakteristik tanah. Hasil penyelidikan menunjukkan bahwa lapisan tanah keras berada pada kedalaman lebih dari 15 meter. Oleh karena itu, digunakan pondasi dalam berupa tiang pancang mini dengan dimensi 20×20 cm yang dipancang menggunakan HSPD untuk mengurangi gangguan pada lingkungan sekitar. Daya dukung pondasi dianalisis dengan metode empiris, yaitu Mayerhoff, Janbu, dan Vesic, serta dibandingkan dengan hasil uji HSPD yang mencerminkan kondisi aktual lapangan. Hasil penelitian menunjukkan bahwa nilai daya dukung izin rata-rata berdasarkan uji HSPD adalah 24,2 ton. Sedangkan hasil dari analisis perhitungan metode empiris diperoleh daya dukung izin rata-rata sebesar 8,34 ton. Perbandingan hasil analisis metode empiris dengan metode statis menggunakan alat HSPD yaitu sekitar lebih kurang tiga kali lipat, dimana nilai analisis metode empiris lebih kecil dari HSPD.
