Abstract

The papaya seed oil is a non-food oil that can be used as raw material for biodiesel. The transesterification process using oil as raw material requires long process stages so it is not efficient. In situ transesterification with a co-solvent is an alternative to overcome this problem. This research aims to obtain optimum conditions for the in situ transesterification reaction of papaya seed oil with THF co-solvent. The research operating conditions included stirring speed 450 rpm, reaction at room temperature, oil:methanol molar ratio = 1:101.39, catalyst:oil molar ratio = 0.5:1, oil:THF molar ratio = 1: 67.85, reaction time are 3, 8, 13, 18, 23, 28 minutes and reactions with and without a NaOH catalyst. The best research conditions were obtained in the in situ transesterification reaction of papaya seed oil with THF co-solvent using a NaOH catalyst at a reaction time of 33 minutes, producing a crude yield of 74.38% and methyl esters concentration of 98,036.4 ppm and physical properties of biodiesel that met SNI 7182-2015, namely density 0.89 g/mL and acid number 0.44 mg KOH/g sample.

Abstract

Essential oil, also known as etheric oil (Aetheric Oil), is a volatile compound widely utilized in various industries, including pharmaceuticals, cosmetics, and aromatherapy. In this study, the main material used is orange peel (Citrus aurantium), which is extracted into essential oil using the Microwave-Assisted Extraction (MAE) method. The study aims to obtain a high essential oil yield with optimal quality. The variations in microwave power used include 100 W, 150 W, 200 W, 280 W, and 399 W, with soaking durations of 3, 4, and 5 days. Various parameters were analyzed to assess the quality of the obtained essential oil, including organoleptic tests (color), yield, refractive index, density measurement, and analysis using Gas Chromatography-Mass Spectrometry (GC-MS). The results indicate that the optimal condition was achieved at a microwave power of 280 W with a soaking duration of 5 days. Under these conditions, the essential oil yield was relatively high, with a refractive index of 1.040 and a density of 1.039. The obtained essential oil had a dark yellow color, indicating good quality. GC-MS analysis revealed that limonene, the main component of orange essential oil, was detected at 1.30% at a retention time of 3.675 minutes, followed by 1.80% at a retention time of 4.240 minutes, and 0.28% at a retention time of 12.750 minutes. Based on these findings, the MAE method proved effective in extracting essential oil from orange peel, particularly under optimal power and soaking conditions. This study provides further insights into efficient extraction techniques for producing high-quality essential oils.

Abstract

Early intervention with cochlear implants and habilitation with auditory-verbal therapy (AVT) methods can promote better development later in childhood. A previous study reported that communication methods,educational methods, duration of communication, frequency of therapy, and type of therapy influencing the effectiveness of amplification in children based on observations from parents. The AVT assessment uses severalassessments that can help determine a child’s hearing skill level, one of which is the early learning accomplishment profile (E-LAP). The study aimed to assess the factors influencing auditory–verbal therapy (AVT) outcomes among children with cochlear implants. It was an analytical observational study with a cross-sectional design in several home therapy. The assessment was using E-LAP. Chi-square test and multivariate logistic regression were used to measure the association between categorical variables. From 52 subjects, there were 32.7% who had received their cochlear implants <3 yr, 67.3% ≥3 yr, 51.9% ≥3 yr using cochlear implant, 53.8% good family participation, 51.9% had undergraduate parents, 71.2% had a profound hearing before implant, 86.5% underwent routine therapy, and 55.8% had a good outcome in AVT. This study showed age of implantation (p= 0.043), optimal family participation (p=0.006), and frequency of AVT (p= 0.002) were related to the outcomes of AVT. From multivariate logistic regression the duration of implant use was the most related (p=0.008). In conclusion, age of implantation, duration of implant use, family participation, and frequency of AVT are related to the outcomes of AVT.
