Abstract

Bathymetric mapping is crucial for marine spatial planning and coastal infrastructure development. However, shallow waters with depths ranging from 0 to 5 meters are considered critical areas that pose dangers to conventional survey vessels. This research examines a bathymetric mapping method for the shallow waters of Kepulauan Seribu, Jakarta, using aerial images captured by an unmanned aerial vehicle (UAV) with a structure-from-motion (SfM) approach. Furthermore, the point cloud must be corrected for the refractive index since light passes through both air and water. The seawater refractive index is derived from salinity and seawater temperature data. The validation process uses several independent control points (ICPs) obtained from GNSS real-time kinematic (RTK) measurements and soundings conducted with an unmanned surface vessel (USV). The accuracy assessment shows that the SfM point cloud data has a horizontal RMSE of 0.103 m and a vertical RMSE of 0.191 m. The aerial image approach significantly speeds up the acquisition process compared to conventional sounding methods and produces a higher density of point clouds, integrating the coastal digital elevation model (DEM) of both land and sea areas. However, the use of this method is limited to clear waters where the seabed is visible in the images.

Abstract

ABSTRAKTujuan penelitian ini adalah untuk mengetahui pengaruh kualitas pelayanan terhadap kepuasan pelanggan pada kantor pos Sindanglaya. Jenis penelitian ini adalah field research dengan pendekatan kuantitatif. Populasi dalam penelitian ini adalah seluruh pelanggan yang menggunakan jasa pelayanan pengiriman barang di kantor pos Sindanglaya Kecamatan Cipanas, Kabupaten Cianjur. Sampel yang diambil sebanyak 100 responden. Teknik pengumpulan data menggunakan kuesioner. Teknik analisis data menggunakan uji analisis regresi linier sederhana. Hasil penelitian ini menunjukkn bahwa variabel kualitas pelayanan memiliki t hitung yang bernilai positif sebesar 0,5688 dengan taraf signifikansi 0,000 diatas signifikansi 0,05 (0,000 < 0,05). Dengan demikian t hitung t tabel (5,688 > 1,984), maka H0 ditolak dan Ha diterima. Sehingga dapat dinyatakan bahwa Kualitas Pelayanan memiliki pengaruh signifikan terhadap Kepuasan Pelanggan pada PT. Pos Sindanglaya. Adapun persamaan analisis regresi linier sederhananya yaitu: ? = 9,118 + 0,139X. ABSTRACTThe purpose of this study was to determine the effect of service quality on customer satisfaction at the Sindanglaya post office. This type of research is field research with a quantitative approach. The population of this study were all customers of the Sindanglaya Post Office. The data collection technique used a questionnaire. The data analysis technique used simple linear regression analysis. The population in this study were all customers who used the delivery service at the Sindanglaya post office. Samples taken were 100 respondents. The results of this study indicate that the service quality variable has a positive t count of 0.5688 with a significance level of 0.000 above the significance of 0.05 (0.000 <0.05). Thus t count t table (5.688> 1.984), then H0 is rejected and Ha is accepted. So it can be stated that Service Quality has a significant influence on Customer Satisfaction at PT. POS. Sindanglaya.

Abstract

This study analyzes how a school principal’s transformational leadership improves teacher performance at an elementary school in the Special Region of Yogyakarta, Indonesia. The research is grounded in the premise that teacher performance is critical to educational quality and that principals play a strategic role in guiding teaching and learning. A qualitative case study design was employed, involving the principal and teachers as participants, to gain an in-depth understanding of leadership strategies. Data were collected through in-depth interviews, non-participant observations, and document analysis, with methodological triangulation enhancing data validity. The principal was found to consistently practice all four dimensions of transformational leadership (Idealized Influence, Inspirational Motivation, Intellectual Stimulation, and Individualized Consideration). Through these practices, the principal served as a disciplined role model, clearly articulated an inspiring vision, fostered innovation via professional development, and provided personalized support to teachers. As a result, teachers’ motivation, commitment, and performance showed significant improvement, leading to higher instructional quality and better student outcomes. These findings provide empirical evidence of the effectiveness of transformational leadership in the primary education context, underscoring the crucial role of principals in creating collaborative, innovative, and quality-oriented school environments.
