Abstract

Bilimbi (Averrhoa bilimbi Linn.) contains saponins which are natural surfactants. Due to their cleaning properties, saponins can be developed as raw materials for detergent production. The synthesis of detergent with the addition of fruits, leaves, and petioles extract of the bilimbi has been successfully carried out. A series of tests, namely organoleptic, pH, foam stability and quantity, hedonic, and detergency tests, were performed to evaluate the quality of detergents. From the organoleptic test, it was found that the addition of the extract caused the detergent to change color to brownish, with a slight increase in density and a slight decrease in pH, and relatively did not change the phase and fragrance of the detergent. The addition of extract did not increase the quantity of foam produced but could increase the stability of the resulting foam. The hedonic test shows a relatively good level of panelist preference. The detergency from the stain removal test shows that the detergent has fairly good detergency.

Abstract

Kitin adalah homopolimer yang tersusun dari N-acetyl d-glucosamine dan glucosamine yang terikat dengan β 1–4 glycosidic. Kitin umumnya diperoleh dari ekstraksi kulit udang melalui proses deproteinasi dan demineralisasi dengan tahapan proses yang lama dan panjang. Pada penelitian ini dilakukan isolasi kitin dari jamur tiram sebagai alternatif sumber bahan baku dengan bantuan reaktor microwave. Proses ekstraksi dilakukan pada variasi waktu antara 5-60 menit untuk memperoleh kadar protein yang optimum. Selanjutnya dilakukan variasi temperatur antara 50-80°C untuk memperoleh kadar kitin. Hasil perolehan kadar protein tertinggi didapatkan pada waktu reaksi selama 60 menit yaitu 99,91% dan kadar kitin tertinggi diperoleh pada temperatur 80°C dengan kadar kitin yang didapatkan sebesar 7,10%.

Abstract

Buah stroberi merupakan komoditas buah-buahan yang bernilai ekonomi tinggi namun umur simpannya pendek. Kerusakan buah disebabkan oleh proses respirasi dan transpirasi. Salah satu cara untuk menekan terjadinya transpirasi yaitu dengan aplikasi edible coating berbahan dasar pati alami seperti pati dari talas beneng. Penelitian ini bertujuan untuk mendapatkan komposisi optimum edible coating dari pati talas beneng dengan campuran lilin lebah dan gliserol terhadap kualitas buah stroberi. Tahapan dalam memproduksi edible coating ini preparasi matrik edible coating dengan cara melarutkan pati dengan konsentrasi 3% dalam akuades. Larutan pati dicampurkan gliserol dengan konsentrasi 0,5; 1; dan 2% (v/v) lalu masing masing campuran ditambahkan lilin lebah dengan variasi konsentrasi 0,4; 0,8; dan 1,6% (w/v). Hasil analisis menunjukkan bahwa edible coating berbasis pati talas beneng pada hari ke 5 didapatkan hasil yang terbaik, dengan penambahan gliserol dengan konsentrasi 1% dan lilin lebah dengan konsentrasi 1,6% memberikan susut bobot dengan nilai terendah 15,7%, menghambat penurunan kadar gula dengan nilai kadar gula 3,2% dan menghambat penurunan kadar vitamin C sebesar 12% sehingga dapat dikatakan bahwa edible coating berbasis pati talas beneng dengan penambahan gliserol dan lilin lebah dapat meningkatkan kualitas buah stroberi.

Abstract

This study examines the effect of UV irradiation on the yield and physical characteristics of biodiesel from candlenut oil using a TiO2-K2O/natural zeolite composite. Natural zeolite was activated with KOH and impregnated with TiO2. The formed composite was analyzed with an X-ray diffractometer. Biodiesel was synthesized with candlenut oil to methanol molar ratio and catalyst loading (w/w oil) 1:4, 1:6, 1:8, and 2, 4, and 6%, respectively. The XRD analysis shows peak patterns of anatase and rutile TiO2, K2O, and zeolite. UV light can increase biodiesel yield, with the highest yield at 82.08% at oil to methanol molar ratio of 1:8 and a catalyst loading of 2%. The physical properties of biodiesel are in accordance with national standard SNI 7182:2015. GCMS results shows that the main components of fatty acid methyl ester from biodiesel are methyl oleate, methyl palmitate, and methyl linoleate.

Abstract

Shallot skin (Allium cepa var. aggregatum) contains secondary metabolites of flavonoid, phenolic, and saponin that can be antibacterial. This research was conducted by extracting the shallot skin using maceration and ultrasound-assisted methods with 3, 5, and 7 days for maceration extraction and 10, 20, and 30 minutes for ultrasonication-assisted extraction (UAE). The extract was then tested for phytochemical screening and analysis of its flavonoid, phenolic, and saponin levels. Three extracts with the best secondary metabolite compounds were then tested for the inhibitory power of the extracts against Escherichia coli through the diffusion method. The results showed that shallot skin extract contained flavonoid and phenolic compounds but not saponin. Based on the analysis of the levels of these compounds using UV-Vis spectrophotometry, three extracts with the highest flavonoid and phenolic content were obtained from maceration extraction for seven days, the UAE method for 20 minutes, and the UAE extraction method for 30 minutes. The extract using the UAE method has relatively higher flavonoid and phenolic content (6.93 and 2.59 ppm, respectively) than the extract using the maceration method (5.48 and 2.46 ppm, respectively), which is also considered more efficient in terms of time. A preliminary antibacterial activity test showed antibacterial activity in the shallot skin.
