ABSTRAK

RINI HAYATI HERMAN : Aktivitas Antioksidan pada Soyghurt dengan
Penambahan Ekstrak Daun Sambung Nyawa (Gynura procumbens) (SoyNuraghurt) terhadap Mencit Penderita Kanker dibimbing oleh HERLA
RUSMARILIN dan LINDA MASNIARY LUBIS.
Penelitian ini dilakukan untuk mengetahui pengaruh pemberian produk
soy-nuraghurt yang dibuat dengan penambahan sari sirsak, ekstrak daun sambung
nyawa dan zat penstabil terhadap kesehatan mencit penderita kanker yang
diinduksi dengan benzo[a]piren. Soy-nuraghurt dianalisis dengan aktivitas
antioksidan, total padatan,
kadar air, kadar abu, kadar protein, kadar lemak,
kadar serat kasar, total asam, total bakteri asam laktat, kadar vitamin C, viskositas,
total gula, total soluble solid, dan uji organoleptik warna, aroma, rasa dan tekstur.
Pengujian in vivo digunakan 36 ekor mencit putih jantan yang dibagi 6 kelompok
yaitu P0 (kontrol), P1 (benzo[a]piren), P2 (ekstrak), P3 (soy-nuraghurt), P4
(benzo[a]piren + ekstrak), P5 (benzo[a]piren + soy-nuraghurt. Parameter yang
dianalisa adalah berat badan, histopatologi hepar dan aktivitas enzim SGPT
(Serum Glutamic Pyruvate Transaminase).
Hasil penelitian menunjukkan bahwa perbandingan sari sirsak dengan

ekstrak daun sambung nyawa memberikan pengaruh berbeda sangat nyata
terhadap aktivitas antioksidan, kadar abu, kadar protein, kadar lemak, kadar serat
kasar, total asam, total bakteri asam laktat, kadar vitamin C, nilai viskositas, total
gula, total soluble solid, nilai hedonik warna, nilai hedonik aroma, dan nilai
hedonik rasa. Perbandingan carboxy methyl cellulose (CMC) dengan gum arab
memberikan pengaruh berbeda sangat nyata terhadap aktivitas antioksidan, total
padatan, kadar air, kadar abu, kadar protein, kadar lemak, kadar serat kasar, total
asam, total bakteri asam laktat, kadar vitamin C, nilai viskositas, total soluble
solid, nilai hedonik aroma, nilai hedonik rasa dan nilai hedonik tekstur. Interaksi
antara kedua faktor memberikan pengaruh berbeda sangat nyata terhadap kadar
protein, kadar lemak, kadar serat kasar, total asam, total bakteri asam laktat,
viskositas, total gula dan total soluble solid.
Perbandingan sari sirsak dengan ekstrak daun sambung nyawa (60% :
40%) dan perbandingan carboxy methyl cellulose (CMC) dengan gum arab (1 : 2)
dipilih untuk pengujian in vivo (sebagai produk terbaik). Pengujian in vivo
menunjukkan bahwa pemberian soy-nuraghurt pada mencit yang diinduksi
benzo[a]piren dapat memberikan efek mencegah, mengurangi dan mengobati
terhadap hepar mencit, menurunkan dan menormalkan kembali aktivitas enzim
SGPT (Serum Glutamic Pyruvate Transaminase) dan menunjukkan perbedaan
yang signifikan terhadap berat badan mencit.

ABSTRACT

RINI HAYATI HERMAN : Antioxidants Activity of soyghurt with Sambung Nyawa
leaves Extract (Gynura procumbens) (Soy-Nuraghurt) on cancer suffered mice,
supervised by HERLA RUSMARILIN and LINDA MASNIARY LUBIS.
This research was conducted to determine the effect of soy-nuraghurt
which had been made by soursop extract, sambung-nyawa leaves extract, and
stabilizers on mice’s health which had suffered from cancer induced by
benzo[a]pyrene. Soy-nuraghurt were analyzed by antioxidant activity, total solids
content, water content, ash content, protein content, fat content, crude fiber
content, total acid,total lactic acid bacteria, vitamin C content, viscosity, total
glucose, total soluble solid and organoleptic tests of color, aroma, flavor and

texture. In vivo analysis was using 36 male mice who were divided into six
groups, i.e : P0 (control), P1 (benzo[a]pyrene), P2 (extract), P3 (soy-nuraghurt),
P4 (benzo[a]pyrene + extract), P5 (benzo[a]pyrene + soy-nuraghurt). In vivo
analyzed were weight, histopathology of hepar, and activity of Serum Glutamic
Pyruvate Transaminase enzyme.
The results showed that the ratio of soursop extract and sambung nyawa
leaves extract had highly significant effect on activity antioxidant, ash content,
protein content, fat content, crude fiber content, total acid, total lactic acid
bacteria, vitamin C content, viscosity, total glucose, the hedonic value of the
color, aroma and flavor. Ratio of carboxy methyl cellulose (CMC) and arabic
gum had highly significant effect on activity antioxidant, solid content, water
content, ash content, protein content, fat content, crude fiber content, total acid,
total lactic acid bacteria, vitamin C content, viscosity, total soluble solid, the
hedonic value of the aroma, flavor and texture. The interaction between two
factors had highly significant effect on protein content, fat content, crude fiber
content, total acid, total lactic acid bacteria, viscosity, total glucose and total
soluble solid.
Ratio of soursop extract and sambung-nyawa leaves of (60%:40%) and
ratio of carboxy methyl cellulose (CMC) and arabic gum of (1:2) had used for in
vivo analysis

(the best product quality). In vivo analysis showed that soynuraghurt benzo[a]pyrene inducted mice could give the preventive effects,
decreased and treated the mice’s hepar, decreased and normalized the activity of
Serum Glutamic Pyruvate Transaminase enzyme and showed highly significant
effect on the mice weight.
