Abstract

Penelitian ini bertujuan untuk menganalisis ketepatan pencatatan transaksi dan pengelolaan piutang dalam meningkatkan kinerja keuangan pada Toko Baju Umi Salamah. Ketepatan pencatatan transaksi merupakan aspek penting dalam menghasilkan laporan keuangan yang akurat dan dapat dijadikan dasar pengambilan keputusan.  Sementara itu, pengelolaan piutang yang baik berperan dalam menjaga likuiditas dan memperlancar arus kas perusahaan. Penelitian ini menggunakan metode deskriptif kualitatif dengan teknik pengumpulan data melalui wawancara, observasi, dan dokumentasi terhadap aktivitas pencatatan transaksi serta pengelolaan piutang yang dilakukan oleh pihak toko. Hasil penelitian menunjukkan bahwa pencatatan transaksi yang dilakukan masih terdapat beberapa kesalahan dan keterlambatan pencatatan, sehingga memengaruhi keakuratan laporan keuangan.  Selain itu, pengelolaan piutang belum berjalan secara optimal karena belum adanya kebijakan tertulis mengenai penagihan dan batas waktu pembayaran. Dengan perbaikan dalam sistem pencatatan transaksi dan penerapan kebijakan pengelolaan piutang yang lebih disiplin, kinerja keuangan Toko Baju Umi Salamah dapat meningkat, baik dari segi efisiensi operasional maupun stabilitas keuangan. Kata Kunci: Ketepatan pencatatan, piutang, pengelolaan, kinerja keuangan, transaks

Abstract

Keratin waste is highly recalcitrant due to its complex protein structure, requiring efficient biodegradation strategies. This study aimed to evaluate and optimize keratinase production of thermophilic Bacillus licheniformis AAL3 isolated from the Air Putih hot spring, Lebong, Bengkulu. Qualitative keratinolytic activity was determined using feather meal agar, while quantitative enzyme activity was measured spectrophotometrically based on tyrosine release. The isolate exhibited a higher keratinolytic index (5.0) compared to B. licheniformis SCL2 (1.5). Quantitative analysis showed that AAL3 produced higher cell density (8.9 × 10? CFU/mL) and keratinase activity (1.0074 U/mL). Optimization studies revealed that maximum keratinase production occurred at 60 °C and pH 9. Among the tested carbon sources, 1% glucose resulted in the highest cell growth and enzyme activity, whereas 0.4% peptone was the most effective nitrogen source. The results demonstrate a strong positive correlation between bacterial growth and keratinase production. These findings indicate that B. licheniformis AAL3 has significant potential as a thermophilic keratinase producer for biotechnological applications, particularly in keratin waste biodegradation.
