Abstract

This study aims to determine the effect of giving sea grape extract (Caulerpa racemosa) in inhibiting Aeromonas hydrophila bacterial infection in tilapia (Oreochromis niloticus) and to determine the concentration of use of sea grape (Caulerpa racemosa) which is effective to inhibit Aeromonas hydrophila bacterial infection in tilapia (Oreochromis niloticus) and this study was an experimental study using a completely randomized design (CRD).The variables observed in this study were changes in fish behavior, fish morphology, fish anatomy, survival, water quality parameters (temperature, DO, pH). The data was processed using the SPSS Version 24 program with Analysis (ANOVA) if there were differences, then continued with Duncan.The results showed that the administration of sea grape extract (Caulerpa racemosa) could inhibit Aeromonas hydrophila bacterial infection in tilapia. The average level of inhibitory power of the extract was the best in treatment C with 25 mg/l of sea grape extract (Caulerpa racemosa) the condition of the fish improved on day 1 postoperatively. immersion and the lowest level of inhibition in the control treatment the condition of the fish was getting worse every day, having a significant effect (P<0.05), the highest survival was in treatment C where survival on day 14 was 73%. Water quality average temperature 27% C, average dissolved oxygen 5-6 ppm and average pH 7.4-7.8

Abstract

Penelitian ini bertujuan mengukur dampak perjanjian perdagangan bebas pada daya saing UMKM di Indonesia. Kami pakai metode kuantitatif, fokus pada regresi linier sederhana untuk olah data. Sumber datanya time series dari tahun 2016-2025, diambil langsung dari BPS dan Kementerian Perdagangan RI. Daya saing UMKM sebagai variabel dependen diukur pakai nilai ekspor Indonesia keseluruhan, sementara perjanjian perdagangan bebas (variabel independen) direpresentasikan oleh ekspor nonmigas kita ke Malaysia. Hasil analisis nunjukin korelasi positif dan signifikan antara keduanya. Ini dibuktikan dengan nilai signifikansi 0,000 (jauh di bawah 0,05) dan koefisien regresi 27,771 yang menandakan pengaruh baik. R² sebesar 0,899 berarti model ini bisa jelasin hampir semua variasi daya saing UMKM. Uji asumsi klasik juga lolos semua: residual berdistribusi normal, bebas heteroskedastisitas, dan nggak ada autokorelasi. Pokoknya, perjanjian perdagangan bebas ini emang krusial buat naikin daya saing UMKM di tanah air..
