Abstract

ABSTRAK
(Sucik Wahyuni. 26020119130042. Pengaruh Larutan Daun Sirih
(Piper betle, Linn.) terhadap Daya Tetas Telur Ikan Mas (Cyprinus carpio, Linn).
Ristiawan Agung Nugroho dan Subandiyono).
Ikan mas merupakan salah satu komoditas akuakultur air tawar yang
banyak dibudidayakan di Indonesia. Pembenihan ikan mas tidak terlepas dari
adanya kendala daya tetas yang masih rendah dapat diketahui dari tingginya
variasi hatching rate 7,81-78,35% yang masih dibawah standar 50-80%. Salah
satu faktor yang dapat menurunkan daya tetas telur ikan mas yaitu serangan jamur
Saprolegnia sp. Tindakan terhadap patogen tersebut selama ini menggunakan
bahan kimia dan sintetis yang tidak dianjurkan yaitu Methylene Blue, Malachite
green, Formalin dan Betadine. Salah satu alternatif obat dari bahan alami yang
lebih aman untuk penanganan dan pengendalian jamur yaitu daun sirih hijau
karena mengandung senyawa antifungal yaitu minyak atsiri, flavonoid, fenol,
saponin dan tanin. Tujuan dari penelitian ini adalah menganalisa pengaruh
pemberian larutan daun sirih sebagai anti jamur terhadap daya tetas. Penelitian
dilaksanakan pada bulan Maret-Mei 2023 di UPT Aneka Usaha Perikanan
Balekambang Solo dan Laboratorium Kering Departemen Akuakultur. Bahan uji
yang digunakan adalah telur ikan mas dan larutan daun sirih. Penelitian ini
menggunakan metode eksperimen dengan rancangan acak lengkap (RAL) 4
perlakuan dan 3 ulangan. Dosis perendaman larutan daun sirih yang digunakan
yaitu A 0 ml/l, B 1 ml/l, C 2 ml/l dan D 3 ml/l. Data yang diamati meliputi
perkembangan telur, hatching rate, survival rate, identifikasi jamur dan kualitas
air. Hasil yang diperoleh dari penelitian menunjukkan bahwa larutan daun sirih
berpengaruh nyata terhadap daya tetas dan kelulushidupan ikan mas. Dosis terbaik
perendaman larutan daun sirih (P.betle) terhadap daya tetas telur dan
kelulushidupan larva ikan mas yaitu perlakuan B dosis 1 ml/l. Pengamatan
kualitas air berupa suhu berkisar antara 24-32,40 C, DO pada media penetasan dan
pemeliharaan berkisar antara 5,2-7,1 mg/L dan pH berkisar antara 7,8-8,41.
Larutan daun sirih berpengaruh nyata terhadap perkembangan telur, daya tetas dan
kelulushidupan larva ikan mas.
Kata Kunci: anti jamur; Cyprinus carpio; daun sirih; daya tetas telur.

ABSTRACT
(Sucik Wahyuni. 26020119130042. The Effect of Betel leaf (Piper
betle, Linn.) Solution on Hatching Rate of Carp (Cyprinus carpio, Linn.).
Ristiawan Agung Nugroho and Subandiyono).
Common carp is a freshwater aquaculture commodity that is widely
cultivated in Indonesia. Common carp hatchery cannot be separated from the
problem of low hatching rate, which can be seen from the high variation in
hatching rate of 7.81–78.35%, which is still below the standard of 50–80%. One
of the factors that can reduce the hatching rate of carp eggs is the attack of the
fungus Saprolegnia sp. The action against these pathogens so far uses chemicals
and synthetics that are not recommended, namely methylene blue, malachite
green, formalin, and betadine. One alternative drug made from natural
ingredients that is safer for handling and controlling fungi is green betel leaf
because it contains antifungal compounds, namely essential oils, flavonoids,
phenols, saponins, and tannins. The aim of this research is to analyze the effect of
giving betel leaf solution as an antifungal on hatchability. The research was
carried out in March–May 2023 at UPT Aneka Usaha Perikanan Balekambang
Solo and Laboratorium Kering of the Aquaculture Department. The test materials
used were common carp eggs and betel leaf solution. This research used an
experimental method with a completely randomized design (CRD) with 4
treatments and 3 replications. The soaking dose of betel leaf solution used was A
0 ml/l, B 1 ml/l, C 2 ml/l, and D 3 ml/l. The observed data included egg
development, hatching rate, survival rate, fungal identification, and water quality.
The results obtained from the study showed that the betel leaf solution had a
significant effect on the hatching rate and survival of common carp. The best dose
of immersing betel leaf (P. betle) solution on egg hatching rate and survival of
carp larvae was treatment B at a dose of 1 ml/l. Observation of water quality in
the form of temperature ranged from 24-32.40 C, DO in hatchery and rearing
media ranged from 5.2-7.1 mg/L, and pH ranged from 7.8-8.41. The betel leaf
solution has a significant effect on egg development, hatchability, and the survival
of carp larvae.
