Abstract

Sistem reservasi berbasis web merupakan penerapan teknologi informasi untuk mempermudah proses pemesanan layanan secara daring. Studio Najwa Record terletak di Belitang OKU Timur, sebelumnya masih menggunakan metode manual yang sering menimbulkan kesalahan pencatatan dan keterlambatan pelayanan. Penelitian ini bertujuan merancang sistem reservasi foto studio berbasis web agar proses pemesanan menjadi lebih efisien dan terintegrasi. Data diperoleh melalui observasi, wawancara, dan studi pustaka. Pengembangan sistem menggunakan metode Waterfall dengan tahapan analisis, perancangan, implementasi, pengujian, dan pemeliharaan. Sistem dibangun menggunakan PHP, MySQL, XAMPP, dan Bootstrap dengan fitur utama pendaftaran pelanggan, pemilihan paket foto, jadwal pemotretan, konfirmasi pembayaran, serta laporan admin. Hasil pengujian menunjukkan sistem berjalan baik dan mampu meningkatkan efisiensi, mengurangi kesalahan pencatatan, serta mempercepat proses pelayanan di Studio Najwa Record.

Abstract

Despite the ecological and economic significance of coral reefs, quantitative data on how water quality parameters regulate zooxanthellae density in anthropogenically impacted tropical reefs remain limited. This study investigated the influence of water quality parameters on zooxanthellae density in branching corals at Pahawang Island, Lampung, Indonesia, across four stations representing different levels of human disturbance: dock area (Station 1), floating net cages area (Station 2), recreational area (Station 3), and a relatively pristine area (Station 4). Coral fragments were collected by SCUBA diving at 2–5 m depth, and zooxanthellae were extracted by homogenization followed by centrifugation, with cell density quantified using a hemocytometer under light microscopy. Physical and chemical water quality parameters were measured in situ using a CTD profiler, while nutrient concentrations were analyzed according to SNI protocols. Zooxanthellae density ranged from 16,822 to 22,227 cells/cm², indicating a healthy symbiotic status across all stations. Principal Component Analysis (PCA) identified dissolved oxygen (5.5–6.4 mg/L), depth (2.20–4.10 m), and water clarity (2.0–3.0 m) as the primary environmental drivers of zooxanthellae density variation, while temperature, pH, and salinity remained stable and within coral-suitable ranges. Hydrodynamic conditions and oxygen availability, rather than nutrient enrichment, appear to be the dominant regulators of zooxanthellae density at this site. These findings highlight the need for site-specific management strategies that prioritize maintaining dissolved oxygen levels and water circulation, and provide a scientific basis for developing zoning policies in coral ecotourism areas of Pahawang Island to ensure long-term reef ecosystem health.

Abstract

This research aims to describe the steps for implementing the project based learning (PjBL) learning model in improving learning outcomes, knowing the increase in learning outcomes. The type of this research is classroom action research (PTK) which is carried out in two cycles. This research was carried out at SD Negeri 33 Mataram with the research subjects being grade 1 students at SD Negeri 33 Mataram with a total of 28 children as subjects. Data collection techniques use test techniques. The data analysis used is quantitative descriptive. The research results show that there is an increase in learning outcomes through the application of the Project Based Learning learning model for grade 1 students at SD Negeri 33 Mataram. This is evidenced by the increase in student learning outcomes with the average student learning outcomes in the initial condition being 55 with 10 students (36%) experiencing an increase in cycle 1 with an average student score of 67 with 17 students (60%) and in cycle 2 The average student score is 82 with the number of students completing as many as 25 or (89%) students completing.
