Kelayakan Usaha Pembesaran Ikan Koi Kolam Konkret dan Kolam Tanah PT Tirta Akatsuki Solaris Kabupaten Bogor

Abstract

Penelitian ini menganalisis perbedaan pertumbuhan dan survival rate ikan koi pada kolam konkret dan kolam tanah, serta kelayakan bisnis pembesarannya di PT Tirta Akatsuki Solaris. Data dikumpulkan melalui observasi partisipatif dan wawancara mendalam pada Juli–Desember 2025. Pertumbuhan panjang mutlak kolam tanah lebih optimal (rata-rata 25,7 cm) dibanding kolam konkret (13,5 cm) selama tiga bulan pemeliharaan berdasarkan uji Independent Sample T-test (p < 0,05), sebaliknya, survival rate kolam konkret lebih tinggi (100%) dibanding kolam tanah (86,3%). Kedua sistem juga layak dari aspek pas ar, teknis, manajemen, sosial budaya, dan lingkungan. Analisis finansial 10 tahun menunjukkan kolam konkret (NPV Rp983.220.596, IRR 18%, PP 6,06 tahun), kolam tanah (NPV Rp5.042.797.045, IRR 72%, PP 3,12 tahun), dan gabungan (NPV Rp6.093.777.052, IRR 46%, PP 3,70 tahun) layak dikembangkan, dengan NPV positif dan IRR melampaui suku bunga berlaku (3%). Kolam tanah dan kombinasi menunjukkan efisiensi keuntungan jauh lebih tinggi dibandingkan kolam konkret.

This study analyzes differences in growth performance and survival rate of koi fish reared in concrete and mudpond, and assesses the business feasibility of koi fish grow-out at PT Tirta Akatsuki Solaris. Data were gathered through participatory observation and in-depth interviews from July to December 2025. Absolute length growth was more optimal in mudpond (25,7 cm on average) than concrete pond (13,5 cm) over three months of rearing (Independent Sample T-test, p < 0,05), conversely, survival rate was higher in concrete pond (100%) than mudpond (86,3%). Both systems are also feasible in market, technical, managerial, socio-economic, and environmental aspects. Over a 10-year horizon, the concrete pond (NPV Rp983.220.596, IRR 18%, PP 6,06 years),mudpond (NPV Rp5.042.797.045, IRR 72%, PP 3,12 years), and combined pond (NPV Rp6.093.777.052, IRR 46%, PP 3,70 years) are all financially feasible, with positive NPV and IRR above the 3% discount rate. Mudpond and combined pond show markedly higher profit efficiency than concrete pond.
