Abstract

The characteristics of night ship passengers are dominated by men, the average age of passengers is 20-25 years with a percentage value of 64%, the most travel destinations are Muna Island and the dominant service users have student jobs, while the analysis results are seen in the value of 0.66- 0.8, this means that the overall CSI score for performance appraisal is 1.96 with the criteria for the value of each indicator, service users are very satisfied with the performance of night ship services on the Kendari - Raha route, Southeast Sulawesi Province. The perception of service users towards night boat services on the Kendari - Raha route as a whole with an average value of 3.5 for performance and 3.1 for satisfaction. This can be seen in the quadrant A diagram in the Cartesian diagram, which means that the service elements are very good and provided very well.

Abstract

The purpose of this study was to (1) analyze the characteristics of fresh concrete with the addition of coconut shell waste (2) to analyze the compressive strength of concrete with the addition of coconut shell. The research location for making concrete was carried out at the Laboratory of the construction of the water resources and community development department of the Southeast Sulawesi provincial government. There were 24 specimens printed in the form of a cylinder with dimensions of 30cm x 15cm with the composition of adding 0%, 5%, 10%, and 15% coconut shell waste. Which was then tested for compressive strength at the age of 7, 14, and 28 days. Based on the compressive strength test with a quality plan of f'c 20 MPa, on the 28 day test with the addition of 0% is 23.71 MPa, the addition of 5% is 20.59 MPa, the addition of 10% is 19.97 MPa, and an additional 15% is 13.53 MPa. Coconut shell as a substitute for coarse aggregate for quality f'c 20 MPa can only be used under 10% of the amount of coarse aggregate.

Abstract

A construction project is an activity that aims to build facilities and infrastructure within the planned timeframe. The project can be defined as an organized effort or activity that uses the available budget and resources that must be achieved to achieve important goals, objectives, and expectations using the existing budget and resources, which must be completed within the planned timeframe so that the project does not experience delays. The purpose of this study was to determine how much work delays, the factors that cause work delays and how much influence the delay factors have on work delays in the Puday- Lapulu Slums Quality Improvement Project. The results of this study indicate the value of SV is Rp. (- 8.25 %) While the value of SPI < 1 is 0.896 < 1, based on the criteria for the value of SV and SPI, it can be said that the work is late and has poor performance. Factors that influence delays are aspects of labor and materials. While the large influence of delay factors on work delays that is 10,9 %.

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.
