Pengaruh Perbandingan Labu Siam dengan Nenas dan Penambahan Gula Terhadap Mutu Selai Oles
ABSTRAK
DAPOT PARULIAN SITIO : Pengaruh Perbandingan Labu siam Dengan Nenas dan Penambahan
gula Terhadap Mutu Selai Oles, dibimbing oleh Sentosa Ginting dan Lasma Nora Limbong.
Penenlitian ini bertujuan untuk mengetahui pengaruh perbandingan labu siam dengan
nenas dan penambahan gula terhadap mutu selai oles. Penelitian ini menggunakan rancangan acak
lengkap (RAL) dengan dua faktor yaitu perbandingan labu siam dengan nenas (N): 90%:10%,
80%:20%, 70%:30%, 60%:40%, dan gula (G): 35%, 45%, 55%, 65%. Parameter yang dianalisa
adalah kadar air, kadar abu, kadar vitamin C, total asam, pH, total padatan terlarut, uji hedonik
warna, aroma, rasa dan uji skor daya oles.
Hasil penelitian menunjukkan bahwa perbandingan labu siam dengan nenas memberikan
pengaruh berbeda sangat nyata terhadap semua paramter kecuali uji skor daya oles. Gula
memberikan pengaruh berbeda sangat nyata terhadap semua parameter. Interaksi perbandingan
labu siam dengan nenas dan gula memberikan pengaruh berbeda sangat nyata terhadap kadar abu
dan uji hedonik aroma, memberikan pengaruh berbeda tidak nyata terhadap kadar air, kadar
vitamin C, total asam, pH, total padatan terlarut, uji hedonik warna, rasa dan uji skor daya oles.
Perbandingan labu siam dengan nenas 60%:40% dan gula 65% menghasilkan selai labu siam yang
terbaik.

ABSTRACT
DAPOT PARULIAN SITIO : The effect of ratio of chayote with pineapple and addition of sugar
on quality of jam, supervised by Sentosa Ginting and Lasma Nora Limbong.
The research was conducted to determine the effect of ratio of chayote with pineapple
and addition of sugar on quality of jam. This research was using a factorial completely
randomized design with two factors: ratio of chayote with pineapple (N) : 90%:10%, 80%:20%,
70%:30%, 60%:40%, and sugar (G): 35%, 45%, 55%, 65%. Parameters observed were water
content, ash content, vitamin C content, total acid, pH, total soluble solid, sensory test of color,
flavor, taste and value skor of spreadness.
The results showed that the ratio of chayote with pineapple had highly significant effect
on all parameters except value of spreadness.. Sugar had highly significant effect on all
parameters. Interaction between ratio of chayote with pineapple and sugar had highly significant
effect on ash content and sensory test flavor, had no significant effect on water content, vitamin C
content, total acid, pH, total soluble solid, sensory test color, taste and value of spreadness. The
ratio of chayote with pineapple of 60%:40% and sugar of 65% produced the best chayote jam.
