Degradasi Protein dan Pemecahan Struktur Kalsium Oksalat Pada Tepung Porang Basah, Tepung Porang Kering dan Sabun Porang 579 HAL d
ABSTRAK
Porang (Amorphopallus muelleri) merupakan salah satu jenis tanaman dari
kelompok umbi-umbian yang tumbuh liar di beberapa tempat di Indonesia. Salah
satu potensi umbi porang adalah mengandung kadar protease dan glukomannan
tinggi yang bagus untuk perawatan kulit, sehingga berpotensi besar dalam industri
komestik. Namun, kandungan oksalat yang tinggi pada porang dapat memicu
terjadinya gatal, sehingga porang yang baik adalah porang yang mengandung
kadar kalsium oksalat rendah. Penelitian ini bertujuan untuk mengetahui jumlah
protein terdegradasi dan perubahan struktur kalsium oksalat pada tepung porang
basah, tepung porang kering dan sabun porang. Penelitian ini menggunakan
Rancangan Acak Lengkap (RAL) faktor tunggal dengan perlakuan pemberian
tepung porang basah, tepung porang kering, dan sabun porang serta masingmasing perlakuan diulang sebanyak tiga kali. Pengamatan perubahan struktur
kalsium oksalat dilakukan dengan mengamati struktur anatomi jarum oksalat pada
preparat tepung porang basah, tepung porang kering dan sabun porang. Data yang
diperoleh dianalisa dengan ANOVA taraf signifikasi 95%. Hasil penelitian
menunjukkan bahwa perbedaan bahan (tepung porang basah, tepung porang
kering, dan sabun porang) tidak berpengaruh nyata terhadap kemampuan
degradasi protein, namun cenderung memperpendek panjang jarum kalsium
oksalat. Sabun porang memiliki kemampuan degradasi protein tertinggi dan
jumlah kalsium oksalat terendah, sementara tepung porang basah memiliki
kemampuan degradasi protein terendah dan jumlah kalsium oksalat tertinggi.
Dengan demikian, umbi porang sangat berpotensi untuk diolah menjadi produk
sabun.
Kata kunci: degradasi protein, kalsium oksalat, tepung porang basah, tepung

ABSTRACT
Porang (Amorphophallus muelleri) is a kind of plant from tubers group that
grow wildly in several places in Indonesia. One potential of porang is containing
the high protease and glucomannan which is useful for skincare, so it has great
potential in the cosmetics industry. However the high number of oxalate content
in porang can trigger itching, so good porang is porang which contains low levels
of calcium oxalate. This study aims to determine the amount of degraded protein
and structural change of calcium oxalate in wet conjuc flour, dry conjuc flour, and
conjuc soap. The study was conducted using a completely randomized design
(CRD) with a single factor treated by adding wet conjuc flour, dry conjuc flour
and conjuc soap with each treatment was repeated three times. The structural
change observation of calcium oxalate is done by observing the anatomical
structure of oxalate needles in the preparations of wet conjuc flour, dry conjuc
flour and conjuc soap. The obtained data was analyzed by ANOVA with a
significance level of 95%. The results showed that differences in ingredients (wet
conjuc flour, dry conjuc flour and conjuc soap) had no significant effect in protein
degradation, but tends to shorthen footage of oxalate needles. Conjuc soap
contained the highest levels of protein degradation ability and the lowest amount
of calcium oxalate, while wet conjuc flour contained lowest levels of protein
degradation ability and highest amounts of calcium oxalate. This research showed
that conjuc had a potential to be processed into soap.
Keywords: Protein degradation, calcium oxalate, wet conjuc flour, dry conjuc
flour, conjuc soap.
