The presence of nutrients such as nitrate and phosphate can have a positive impact on phytoplankton growth. However, if the nutrient concentration is very high in the waters, it can cause an explosion in the phytoplankton population or Harmful Algae Blooms (HABs) in the waters. Phytoplankton explosions in waters have a negative impact on the surrounding ecosystem, marine biota, and humans. This research aimed to analyze the spatial distribution and structure of phytoplankton communities that can potentially cause HABs in the waters of Laikang Bay, South Sulawesi. This research was conducted in June 2021. The research found 20 species of phytoplankton HABs from 2 classes, namely Bacillariophyceae (8 types) and Dinophyceae (12 species). The Bacillariophyceae class has a higher percentage, 93%, and Dinophyceae at 7%. The abundance status of phytoplankton HABs is classified as not blooming, with the highest abundance found at Station 4 (control), namely 210 ± 80 cells/L. The HABs phytoplankton diversity index (H') is moderate with a value of 1.576 – 2.332, the uniformity index (E) of Station 1 (west) and Station 4 (control) is moderate with a value of 0.568 and 0.582 while Station 2 (north) and Station 3 (south) is classified as high, namely 0.807 and 0.823, the dominance index (D) is classified as low with a value of 0.135 – 0.357. Spatially, phytoplankton HABs based on the station can be divided into five groups. The results of the PCA analysis show that substations 1.A, 1.B, 1.C, 2.A, 2.B, and 2. C are characterized by high temperature and salinity parameters. Substations 3.A, 3.B, and 3.C are characterized by high nitrate and phosphate parameters. Meanwhile, substations 4.A, 4.B, and 4.C are characterized by high parameters of brightness, current speed, and pH and are associated with a high abundance of phytoplankton HABs.

ABSTRACT - Phytoplankton are plants of very small size, their life hovering in waters. Changes in the abundance of types and also the structure of their communities, can be explained by the analysis of the Redfield Ratio. The Redfield ratio is defined as a comparison of the content of N and P types of nutrients in a body of water. For this reason, the purpose of this study is to analyze the Ratio of Redfield to the suitability of phytoplankton life in the Lantebung mangrove ecosystem in Makassar City. The results showed that as many as 19 phytoplankton genera classified into 3 classes were found, namely the Bacillariophyceae class consisting of 14 genera, Cyanophyceae 1 genus, and Dinophyceae 4 genera. The genus of phytoplankton found at all stations is Rhizosolenia and Chaetoceros. These two types of phytoplankton are the Bacillariophyceae group. The results of the Redfield Ratio analysis are not optimal for phytoplankton growth, the ratio is below 16 Based on this, the redfield ratio is not in accordance with phytoplankton life in the Lantebung mangrove ecosystem in Makassar City. The results of pearson's correlation analysis between Redfield Ratio and phytoplankton abundance were 50.7 %. Keywords: Redfield ratio, phytoplankton abundance, Lantebung, Makassar City.

Penelitian ini bertujuan untuk mengetahui sistem akuntansi pembiayaan gadai emas pada PT Pegadaian (Persero) Cabang Pinrang. Teknik pengumpulan data dilakukan melalui observasi langsung terhadap aktivitas operasional, dokumentasi internal perusahaan, serta wawancara dengan karyawan bagian pembiayaan. Berdasarkan hasil observasi, diperoleh informasi bahwa proses pembiayaan gadai emas dimulai dengan penerimaan jaminan emas dan fotokopi identitas diri nasabah (KTP). Setelah itu, dilakukan penaksiran emas oleh petugas taksir menggunakan alat uji khusus untuk memastikan kadar dan keaslian emas. Nilai taksiran ini digunakan sebagai dasar penentuan besaran pinjaman, dengan rasio pencairan sekitar 85% hingga 92% dari nilai taksiran. Sistem akuntansi yang digunakan dalam pencatatan transaksi pembiayaan gadai emas telah berbasis komputerisasi dan terintegrasi secara nasional melalui sistem informasi manajemen internal Pegadaian. Proses pencatatan berlangsung otomatis, mencakup akun-akun seperti kas, piutang pembiayaan, pendapatan administrasi, dan pendapatan bunga. Hal ini mendukung keakuratan laporan keuangan dan efisiensi operasional. Wawancara dengan pihak internal mengungkap bahwa prosedur pelayanan gadai emas tergolong cepat dan efisien. Waktu yang dibutuhkan mulai dari penyerahan jaminan hingga pencairan dana umumnya kurang dari 15 menit. Hal ini karena sistem kerja telah terbagi secara terstruktur antara petugas taksir, analis kredit, dan kasir. Dari dokumentasi yang diperoleh, diketahui bahwa Pegadaian juga memiliki sistem pengendalian internal yang baik. Pemisahan fungsi kerja, pembatasan akses sistem, serta pemeriksaan berkala menjadi bagian dari upaya pengendalian terhadap risiko keuangan dan kesalahan pencatatan.
