Abstract

The Salvinia molesta plant is classified as a nuisance and is found in waters. In a good-quality environment, the growth of Salvinia molesta can increase rapidly. Their growth causes light to be unable to enter the waters, and the ecosystem is disrupted until it does not work. The constituent elements of the Salvinia molesta body are cellulose in the cell walls and can be used as animal feed, fuel and alternative energy sources. The utility of Salvinia molesta can reduce the population density, so that disturbances in the aquatic ecosystem can also be reduced. The study aims to quantitatively analyze cellulose in floating and sinking leaves following the Wendee and Cheson-Datta methods. The stages carried out are extracting fiber and determining the cellulose fraction. The results of the analysis of cellulose in sinking and floating leaves have average values ​​of 25.5 ± 2.41% and 18.2 ± 5.85%, respectively. Based on the independent t-test, the average percentage of cellulose did not have a significant difference or was not statistically significant because it had a p-value of 0.084 (p>0.05).

Abstract

Waste is currently an environmental problem, and there is a high volume of organic waste, primarily from household and restaurant food waste. Delignification is a process of destroying lignin molecules from the lignocellulose structure with the use of an agent. This study aimed to determine the effect of Hydrogen peroxide ((H2O2) on the water content of delignified flour raw materials and to determine the difference in water content values ​​between the control and treatment of solid food waste fibres. This study used a completely randomized design (CRD) with two factors. The first factor is the concentration level of H2O2 solution with 0%, 0.25%, 0.5%, 0.75%, and 1%; the second factor is the soaking time with 0, 2, 4, and 6 hours of soaking. Data analysis used Two-way ANOVA without replication and the Duncan Multiple Range Test (DMRT). The highest average water content was found at a soaking time of six hours, which was 39.29 g, while the highest average water content was at a concentration factor of 0.25%, 22.8625 g. The Soaking time factor (P=3.54x10-2) and concentration (P=0.131). Based on the analysis, the concentration of H2O2 did not affect the water content of the raw material of flour from the delignification of solid food waste fibre, and the soaking time at the level of six hours of soaking, there was a significant difference (P<0.05) in soaking time according to the Duncan test. Keywords: Delignification, Hydrogen Peroxide (H2O2), Food Solid Waste ABSTRAK Sampah saat ini menjadi permasalahan lingkungan dan tingginya volume sampah organik, terlebih dari sisa makanan rumah tangga dan restoran. Delignifikasi merupakan suatu proses perusakan molekul lignin dari struktur lignoselulosa dengan penggunaan suatu agen. Tujuan penelitian ini untuk mengetahui pengaruh pemberian Hidrogen peroksida (H2O2) terhadap kadar air bahan baku tepung delignifikasi dan mengetahui perbedaan nilai kadar air antara kontrol dan perlakuan pada serat limbah padat makanan. Penelitian ini menggunakan rancangan acak lengkap (RAL) dengan dua faktor. Faktor pertama adalah level konsentrasi larutan H2O2 dengan 0%, 0,25%, 0,5%, 0,75%, dan 1%,  faktor kedua adalah lama perendaman dengan 0, 2, 4, dan 6 jam perendaman. Analisis data menggunakan Two-way ANOVA without replication dan uji Duncan Multiple Range Test (DMRT). Rata-rata kadar air tertinggi terdapat pada lama perendaman enam jam yaitu 39,29 g, sedangkan rata-rata kadar air tertingi pada faktor konsentrasi 0,25% yaitu 22,8625 g. Faktor lama perendaman (P=3,54x10-2) dan konsentrasi (P=0,131). Berdasarkan analisis konsentrasi H2O2 tidak berpengaruh terhadap kadar air bahan baku tepung dari delignifikasi serat limbah padat makanan, dan lama perendaman pada tingkat enam jam perendaman terdapat perbedaan nyata (P<0,05) waktu perendaman menurut uji Duncan.

Abstract

Red pomegranate leaves (Punica granatum L.) is one of the plants that has many benefits and potential as herbal medicine. Red pomegranate leaves have bioactivities such as alkaloids, flavonoids, phenols, saponins, tannins and terpenoids so that they can be used as an alternative antioxidant. This study aims to determine the comparison of the amount of total phenol content in red pomegranate leaves extract using maceration and digestion extraction methods. Total phenol content was determined using the Folin Ciocalteau method with a spectrophotometer UV-Vis. The research method carried out was descriptive experimental quantitative and data analysis was carried out using one way ANOVA. The results of the determination of total phenol content in gallic acid obtained a regression equation y = 0.012x + 0.545 with R2 = 0.9981. The results showed that the total phenol content in the ethanol extract of red pomegranate leaves was greater with the maceration method of 91.83 (µg GAE/g sample) compared to the digestion method of 83.27 (µg GAE/g sample). It can be concluded that the two methods used on red pomegranate leaf samples have no significant difference in total phenol content.
