Abstract
Soap is a surfactant that is used with water for washing and cleaning. Utilization of
used palm cooking oil as a raw material for making liquid hand soap is an
alternative in an effort to manage waste palm oil used. The addition of clove flower
extract as an antiseptic adds to the value of its benefits. This study aims to
determine the effect of variations in KOH solution on the quality of hand soap
made from a mixture of purified palm cooking oil and clove flower extract
(Syzygium aromaticum L). This study used a factorial Completely Randomized
Design (CRD) with 30% KOH variation, namely 20 ml, 25 ml, 30 ml and 35 ml.
Based on the results of the study, it can be concluded that the results of observing
variations in KOH obtained test results; pH, foam height, foam stability, moisture
content, saponification number and organoleptic. The best results were found in the
30% KOH variation, namely 25 ml, with an average standard pH of 10.46, initial
foam height 8.5 cm, final foam height 8 cm, foam stability 90.83%, moisture
content 56.5%, number saponification 70,125, organoleptic like having a slightly
thick texture, and has a light brown color. Based on the results of the KOH
variation above, it has met the standard for liquid hand soap (Indonesian national
standard 06 – 3235-1994), namely the quality requirements for liquid hand soap.

Abstrak
Sabun merupakan surfaktan yang digunakan dengan air untuk mencuci dan
membersihkan. Pemanfataan minyak jelantah kelapa sawit sebagai bahan baku
pembuatan sabun cuci tangan cair merupakan alternatif dalam upaya pengelolaan
limbah minyak jelantah kelapa sawit. Penambahan ekstrak bunga cengkeh sebagai
antiseptik menambah nilai manfaatnya. Penelitian ini bertujuan untuk mengetahui
pengaruh variasi larutan KOH terhadap kualitas sabun cuci tangan berbahan baku
campuran minyak jelantah kelapa sawit yang di murnikan dan ekstrak bunga
cengkeh (Syzygium aromaticum L). Penelitian ini menggunakan Rancangan Acak
Lengkap (RAL) satu faktorial dengan variasi KOH 30 % yaitu 20 ml, 25 ml, 30 ml
dan 35 ml. Berdasarkan hasil penelitian dapat disimpulkan hasil pengamatan variasi
KOH diperoleh hasil uji; pH, tinggi busa, stabilitas busa, kadar air, bilangan
penyabunan dan organoleptik. Hasil terbaik terdapat pada variasi KOH 30% yaitu
25 ml, dengan rata rata pH standar 10,46, tinggi busa awal 8,5 cm, tinggi busa akhir
8 cm, stabilitas busa 90,83 %, kadar air 56,5 %, bilangan penyabunan 70,125,
