Abstract

Kualitas air merupakan faktor penting bagi kelangsungan hidup ikan koi. Penelitian ini bertujuan untuk mengetahui konsentrasi nitrat dan amonia yang didukung parameter kecerahan, suhu, TDS, pH, dan DO, serta menganalisis keterkaitannya terhadap kelayakan budidaya berdasarkan PP No. 22 Tahun 2021. Penelitian dilaksanakan selama 4 minggu dengan pengambilan sampel satu kali setiap minggu. Suhu, kecerahan, dan DO dianalisis langsung di Balai Benih Ikan Pandak; TDS, pH, dan amonia dianalisis di Laboratorium Fakultas Perikanan dan Ilmu Kelautan Universitas jenderal Soedirman; sedangkan nitrat dianalisis di Laboratorium Tanah, Fakultas Pertanian Universitas Jenderal Soedirman. Hasil menunjukkan bahwa konsentrasi nitrat berada di bawah baku mutu (1,300–1,677 mg/L). Sementara itu, konsentrasi amonia mengalami fluktuasi dan pada beberapa waktu melebihi batas aman (0,2 mg/L), yang berpotensi menurunkan kualitas air. Parameter pendukung seperti suhu (23–25°C), pH (7,3–7,8), TDS (67–79 mg/L), kecerahan (25–27,5 cm), dan DO (6,1–8 mg/L) masih berada dalam kisaran optimal. Analisis PCA menunjukkan adanya hubungan negatif antara amonia dan oksigen terlarut (DO), serta kedekatan antara nitrat dan kecerahan, yang mengindikasikan kondisi perairan relatif jernih dengan kadar nitrat yang tidak terakumulasi dalam jumlah besar. Secara keseluruhan, kondisi perairan masih layak untuk budidaya ikan koi, namun diperlukan pengelolaan kualitas air yang lebih baik agar mendukung pertumbuhan ikan secara optimal. Kata Kunci: Kualitas air, Nitrat; Amonia, Ikan koi, PCA

Abstract

The high smartphone ownership among junior high school students in Banyumas Regency (99%) has not been matched by their use to support physical fitness. The majority of device use is limited to entertainment (games or social media), and smartphone ownership has not been fully leveraged for its functions or its role in supporting physical activity. This community service program aims to educate and train students and teachers in utilizing smartphone-based sports applications to support higher-quality physical activity. The activity was carried out in partnership with the Subject Teacher Working Group (MGMP) Physical Education, Sports, and Health (PJOK) Junior High School (SMP) Sub Rayon 06 Banyumas, involving 16 teachers and 547 students. The implementation methods included socialization, training in the implementation of the Strava (performance monitoring) and IQAir AirVisual (environmental air quality monitoring) applications, and monitoring and evaluation. The activity results showed significant behavioral changes, with 99% of participants adopting the technology. This program successfully transformed smartphones from mere entertainment devices into health-tech tools, improved students' digital literacy, and created a safe, measurable, and data-driven sports culture in the school environment.
