Abstract

The development of construction development is currently experiencing rapid progress, which has led to an increase in demand for construction materials. Therefore, other materials are needed as or at least materials capable of reducing the use of aggregate for use in making concrete. This effort is an alternative to utilizing waste from the agricultural plantation industry or factory waste that is left alone. The aim of this research is to analyze the characteristics and compressive strength of concrete with bottom ash as a fine aggregate additive and fly ash as an additive to cement. The location for the concrete making research was carried out at the UPTD Construction Laboratory of the water resources and community development service of the Southeast Sulawesi provincial government. With a total of 16 test objects, they were printed in a cylindrical shape with dimensions of 30 x 15 cm. Based on compressive strength testing with an f'c quality plan of 20 MPa, with 10% substitution of fly ash as cement and bottom ash as fine aggregate with variations of 10%, 15%, 20%, the compressive strength decreased. for 7 days of age respectively, it is 12.31 MPa, 11.89 MPa, and 11.46 MPa. Meanwhile, at the age of 28 days, respectively, it was 19.11 MPa, 16.99 MPa and 15.29 Mpa

Abstract

ABSTRAK Pembangunan/Peningkatan prasarana infrastruktur akan memberi dampak pada berbagai hal yang terkait dengan infrastruktur tersebut. Pemerintah Kota Kendari saat ini sedang membangun Jalan Lingkar Kota Kendari yang dilaksanakan secara bertahap (multy year). Dimana pembangunan itu berupa peningkatan jalan yang sudah ada (jalan kolektor) atau pun membangun pada lahan baru. Adanya pembangunan jalan lingkar tersebut secara langsung akan berdampak pada kenaikan harga lahan pada lokasi yang dilakukan pembangunan/peningkatan jalan. Penelitian ini bertujuan untuk mengetahui harga lahan dari sebelum dilakukan pembangunan dan harga lahan pada saat ini. Penelitian ini adalah penelitian Non-eksperimental yang sifatnya deskriptif, yaitu memberikan gambaran terhadap kondisi objek penelitian sebagaimana adanya. Jenis studi dilakukan dengan wawancara dan survey melalui kuesioner kepada responden, kemudian dilakukan analisis untuk menghasilkan suatu kesimpulan berdasarkan data yang ada. Terjadi perubahan harga lahan yang signifikan dari sebelum dibangun jalan lingkar dan harga saat ini. Terjadi kenaikan harga lahan dari tahu 2008 sampai dengan 2015 sebesar 220% dan tahun 2008 – 2023 kenaikan sebesar 210%. Factor Variabel jarak, luas dan lebar jalan berpengaruh signifikan terhadap kenaikan harga lahan. Model Persamaaan perhitungan nilai jual lahan adalah Y = -270683,63 – 2834,15X1 + 3198,80 X2 + 130532,85X3 Kata kunci : harga lahan; Pengaruh; Peningkatan

Abstract

The Pure-Raha ferry port in Southeast Sulawesi Province is a port that serves passenger and goods crossings connecting the mainland of Buton Island and Muna. Good service quality is one of the determining factors for the company's success. The research method is structured through interviews with respondents by answering the questions in the questionnaire. The analysis used uses Importance Performance Analysis (IPA) and Customer Statistics Index (CSI). The research results show that the consumer satisfaction index for the service performance of the Pure-Raha ferry port in Southeast Sulawesi Province is 0.71. This shows that consumers are satisfied with the quality of port services by 71%. However, the management needs to create a special queue for motorbike riders.
