Abstract

Sound healing, or commonly referred to as music therapy using Acoustic Sound for Wellbeing (ASW) Moringa seed oil (Moringa oleifera Lam.) has significant potential for use in various industrial sectors, including food, pharmaceuticals, and cosmetics. One of the critical factors influencing oil extraction efficiency is preheating treatment and extraction process duration. This study aims to evaluate the effect of varying preheating temperatures and Soxhlet extraction times on the yield of Moringa seed oil, as well as to determine the most optimal extraction conditions. The extraction process was conducted using the Soxhlet method with n-hexane as the solvent. Preheating temperatures used in this study ranged from room temperature to 50°C, 60°C, and 70°C, with extraction times of 2, 4, and 6 hours. The results showed that preheating treatment on moringa seeds and extraction duration had a significant impact on oil yield. The optimal conditions were achieved at a preheating temperature of 70°C with an extraction time of 6 hours, yielding the highest oil recovery of 41.74%.

Abstract

Dependence on solar power needs can be overcome by switching to renewable energy, namely biodiesel. Biodiesel can be synthesized from non-food vegetable oil, namely nyamplung seed oil, with the help of a catalyst. The aim of this research is to optimize the synthesis of biodiesel from nyamplung seed oil through a transesterification reaction using a TiO2 catalyst. Variations in reaction conditions include the mole ratio of oil: methanol, catalyst mass, reaction time and reaction temperature. The optimum conditions for biodiesel synthesis were obtained at mole ratio of oil: methanol  1:8; catalyst 0.15 g; reaction time 150 minutes and reaction temperature 60℃ with an average yield of 76.54%. The characteristics of the biodiesel obtained include  0.877 g/mL of density, 3.65 cSt of viscosity,   234.217 mg KOH/g of saponification value, and 2.1 mg NaOH/g of acid value. The chemical composition of biodiesel resulting from GC-MS is methyl palmitate, methyl oleate and methyl stearate.
