ABSTRAK
Daninta Ratri Imansari. 26060117120002. Aktivitas Antibakteri Daun Mangrove
(Rhizopora sp.) Terhadap Udang Vaname (Litopenaeus vannamei) Selama
Penyimpanan Dingin. (Putut Har Riyadi dan Laras Riyaningsih).
Udang merupakan salah satu komoditas hasil perikanan yang banyak
dikonsumsi oleh masyarakat Indonesia tetapi mudah mengalami kemunduran mutu.
Penyimpanan dingin dan antibakteri berguna untuk menghambat pertumbuhan bakteri,
dimana ekstrak daun mangrove (Rhizopora sp.) mengandung senyawa aktif. Metode
penelitian menggunakan Rancangan Acak Lengkap (RAL) split plot in time dengan
dua faktor yaitu konsentrasi ekstrak daun mangrove (0% dan 25%) dan lama
penyimpanan (0, 3, 6, 9 dan 12 hari) dengan parameter uji yaitu pH, TPC, melanosis
dan organoleptik. Hasil data parametrik dianalisis lebih lanjut menggunakan ANOVA
serta uji BNJ, sedangkan data non-parametrik dianalisis menggunakan uji kruskal
wallis. Hasil penambahan antibakteri daun mangrove mampu menghambat
pertumbuhan bakteri dengan nilai TPC pada hari ke-12 yaitu sebesar 2,2×105 CFU/g
dengan batas maksimal BSN 5,0×105 CFU/g. Hasil penelitian didapatkan penambahan
antibakteri ekstrak daun mangrove memberikan pengaruh nyata (P<5%) terhadap nilai
pH, TPC dan nilai sensori udang secara keseluruhan tetapi tidak berpengaruh nyata
(P>5%) terhadap melanosis.

ABSTRACT
Daninta Ratri Imansari. 26060117120002. Activity Of Rhizophora sp.
Extracts As Antibacterial On Shrimp During Cold Storage.
(Putut Har Riyadi dan Laras Riyaningsih).
Shrimp is one of the fishery productsthat is widely consumed by the people of Indonesia
but it is easy to experience quality deterioration. Cold storage and antibacterial are
useful for inhibiting bacterial growth, where mangrove leaf extract (Rhizopora sp.),
contains active compounds. The research method used a completely randomized design
(CRD) split-plot in time with two factors, namely the concentration of mangrove leaf
extract (0% and 25%) and storage time (0, 3, 6, 9 and 12 days) with test parameters
namely pH, TPC, melanosis and organoleptic. The results of the parametric data were
further analyzed using ANOVA and the BNJ test, while the non-parametric data were
analyzed using the Kruskal Wallis test. The results of the addition of antibacterial
mangrove leaves were able to inhibit bacterial growth with a TPC value on day 12
which was 2,2×105 CFU/g with a maximum limit of 5,5 ×105 CFU/g. The results
showed that the addition of antibacterial mangrove leaf extract had a significant effect
(P<5%) on the overall pH, TPC and sensory values of shrimp but had no significant
(P>5%) effect on melanosis.
