Abstract

Penelitian tentang perbandingan campuran beton dengan cara perendaman dan tidak di rendam, dilakukan dengan menggunakan metode eksperimental yang dilakukan di laboratorium teknik sipil Universitas 17 Agustus 1945 Samarinda. Metode ini menggabungkan bahan material agregat halus ex. Tenggarong, ex. Palu dan agregat kasar ex. Palu untuk pembuatan sampel beton pada umur 3, 7, 14, 21 dan 28 hari melalui cara perhitungan mix design dan perhitungan faktor koreksi. Kuat tekan beton rencana f’c = 20.75 Mpa pada bahan material agregat halus ex. Tenggarong, ex. Palu dan agregat kasar ex. Palu dengan perawatan direndam didapat hasil kuat tekan pada umur 3 hari f’c 28.82 Mpa, 7 hari f’c 26.11 Mpa, 14 hari f’c 23.91 Mpa, 21 hari f’c 23.58 Mpa dan 28 hari f’c 24.43 Mpa. Untuk yang tidak direndam didapat hasil kuat tekan pada umur 3 hari f’c 25.41 Mpa, 7 hari f’c 21.93 Mpa, 14 hari f’c 19.29 Mpa, 21 hari f’c 16.44 Mpa dan 28 hari f’c 16.97 Mpa. Dari hasil analisa tersebut dapat diketahui bahwa beton yang dirawat dengan perendaman dapat mencapai kuat tekan rencana sedangkan yang tidak direndam tidak dapat mencapai kuat tekan rencana.

Abstract

This study aims to analyze the influence of tourist attractions, facilities, and promotions on the number of tourists visiting Celosia Flower Park. The selection of this topic is based on the importance of the role of the destination as one of the main attractions in its area, but faces challenges in maintaining the consistency of the number of tourist visits. The method used is quantitative with a survey approach, using a questionnaire as an instrument for data collection. The sample consisted of visitors to Celosia Flower Park, and the data was analyzed using multiple linear regression techniques using SPSS software. The results showed that the three independent variables of tourist attractions, facilities, and promotions had a significant effect both simultaneously and partially on the number of tourist visits. Promotion proved to be the most dominant factor, followed by attractions and facilities. The R Square value of 0.653 indicates that the model can explain 65.3% of the variation in the number of tourists. These results emphasize the importance of an effective promotion strategy, supported by the development of attractions and improvement of facilities, in order to increase the competitiveness of tourist destinations. This study provides an empirical contribution for tourism managers in designing data-based policies to increase visits sustainably.
