Abstract

This study aims to analyze the effect of commercial papain enzyme with different concentrations and duration of soaking on increasing the degree of hatching of pearl catfish (Clarias gariepinus) eggs. The study used a Randomised Group Design (RAK) with variations in papain enzyme concentration (0, 2, 4, 6, and 8 ppm) and soaking duration (5, 10, and 15 minutes). The results showed that papain enzyme concentration and soaking duration significantly affected the degree of hatching (p < 0,001). The optimal concentration of papain enzyme was 6 ppm with a soaking duration of 10 minutes, resulting in the highest hatching rate of 70,52%±2,92. The lowest egg adhesion was produced at a concentration of 8 ppm with a duration of 15 minutes (32%±4,00), while the highest degree of fertilization was directed at a concentration of 6 ppm with a duration of 10 minutes (79%±3,61). The measurement results of water quality parameters are: temperature 25,6-26,4°C, pH 7,12-7,47, and dissolved oxygen 4,06-4,41 ppm. These results indicate that the papain enzyme effectively reduces egg adhesion and increases the hatching rate of pearl catfish eggs.  Keywords: mutiara catfish; papain enzyme; hatching rate; concentration; immersion duration.   Abstrak Penelitian ini bertujuan untuk menganalisis pengaruh enzim papain komersial dengan konsentrasi dan durasi perendaman yang berbeda terhadap peningkatan derajat penetasan telur ikan lele mutiara (Clarias gariepinus). Penelitian menggunakan Rancangan Acak Kelompok (RAK) dengan variasi konsentrasi enzim papain (0, 2, 4, 6 dan 8 ppm) dan durasi perendaman (5, 10 dan 15 menit). Hasil penelitian menunjukkan bahwa konsentrasi enzim papain dan durasi perendaman berpengaruh signifikan (p <0,001) terhadap derajat penetasan. Konsentrasi optimal enzim papain adalah 6 ppm dengan durasi perendaman 10 menit, menghasilkan derajat penetasan tertinggi sebesar 70,52%±2,92. Daya rekat telur terendah dihasilkan pada konsentrasi 8 ppm dengan durasi 15 menit (32%±4,00), sedangkan derajat pembuahan tertinggi dihasilkan pada konsentrasi 6 ppm dengan durasi 10 menit (79%±3,61). Hasil pengukuran parameter kualitas air yaitu: suhu 25,6–26,4°C, pH 7,12–7,47 dan oksigen terlarut 4,06–4,41 ppm. Hasil ini menunjukkan bahwa enzim papain efektif mengurangi daya rekat telur dan meningkatkan derajat penetasan telur ikan lele mutiara.  Kata kunci: ikan lele mutiara; enzim papain; derajat penetasan; konsentrasi; durasi perendaman

Abstract

This study aims to (1) evaluate the concentration of detergents in the water of the Dayanan River, (2) analyze the ability of Pistia stratiotes to reduce detergents, and (3) evaluate the effect of phytoremediation media on the physiological response of carp (Cyprinus carpio). The study used a Complete Random Design (RAL) with a plant contact time treatment of 3 and 6 days on two types of media (river water and well water + 10 mg/L detergent), as well as three replicas. Detergent analysis was carried out using the SNI 06-6989.51-2005 spectrophotometry method. The results showed that the highest concentration of detergent in the Dayanan River was found in the middle (0.0497 mg/L). Pistia stratiotes effectively reduced detergent significantly (p = 0.025) with optimal time on the third day. The fish response showed an increase in the frequency of operculum opening on the third day (p = 0.004) and no mortality was found for 48 hours. These results prove that Pistia stratiotes is effectively used as a natural biofilter to reduce the detergent content in waters. Keywords: detergent, Pistia stratiotes, phytoremediation, common carp (Cyprinus carpio), Dayanan River Abstrak Penelitian ini bertujuan untuk (1) mengevaluasi konsentrasi detergen dalam air Sungai Dayanan, (2) menganalisis kemampuan Pistia stratiotes dalam mereduksi detergen, dan (3) mengevaluasi efek media hasil fitoremediasi terhadap respon fisiologis ikan mas (Cyprinus carpio). Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan perlakuan waktu kontak tanaman 3 dan 6 hari pada dua jenis media (air sungai dan air sumur + detergen 10 mg/L), serta tiga ulangan. Analisis detergen dilakukan menggunakan metode spektrofotometri SNI 06-6989.51-2005. Hasil penelitian menunjukkan bahwa konsentrasi detergen tertinggi di Sungai Dayanan terdapat pada bagian tengah (0,0497 mg/L). Pistia stratiotes efektif mereduksi detergen secara signifikan (p = 0,025) dengan waktu optimal pada hari ketiga. Respon ikan menunjukkan peningkatan frekuensi bukaan operkulum pada hari ketiga (p = 0,004) dan tidak ditemukan mortalitas selama 48 jam. Hasil ini membuktikan bahwa Pistia stratiotes efektif digunakan sebagai biofilter alami untuk menurunkan kandungan detergen di perairan.
