Abstract

Background: Oil palm empty fruit bunches (OPEFB) represent the largest form of solid waste generated from palm oil production, comprising approximately 23 % of the weight of every ton of fresh fruit bunches (FFB) processed. Untreated OPEFB waste causing pollution problems and increase toxicity due to methane emission. This study aims to evaluate the potential of OPEFB as a growth substrate for the cultivation of Pleurotus ostreatus and Volvariella volvacea, as well as to assess the reduction in lignocellulosic content following fungal biodegradation. Methodology: The experiment was conducted using solid-state fermentation (SSF), and lignocellulose content was analyzed using the Chesson method and SNI 0429:2008 through descriptive quantitative analysis. Findings: Over a 21-day incubation period, mycelial growth of both fungi successfully colonized the OPEFB baglogs, resulting in a 1–2 % reduction in baglog weight. Both P. ostreatus and V. volvacea demonstrated the ability to degrade lignocellulose by secreting lignin peroxidase (LiP), manganese peroxidase (MnP), laccase, cellulase, and hemicellulase enzymes. Initial lignocellulose levels of OPEFB were 18 % lignin, 57 % cellulose, and 20 % hemicellulose. After 21 days of incubation, P. ostreatus reduced these levels to 10 %  lignin, 47 % cellulose, and 19 % hemicellulose, while V. volvacea reduced them to 11 % lignin, 52 % cellulose, and 18 % hemicellulose. Contribution: These findings indicate that OPEFB is a viable substrate for mushroom cultivation and can be effectively biodegraded by these fungi, offering a sustainable approach to managing palm oil industry waste. The treated OPEFB can be used as organic fertilizer, animal feed, and briquettes

Abstract

Background: Lactic Acid Bacteria (LAB) as probiotics provide many benefits to the body, including suppressing the growth of pathogens in the digestive tract. Antibacterial compounds from LAB can inhibit the presence of pathogenic bacteria. This study aimed to determine the ability of antibacterial compounds from Gatot LAB to inhibit the growth of Escherichia coli and Salmonella typhi bacteria. Methodology: LAB was isolated from cassava gatot, and The LAB isolates obtained were then tested for several LAB characteristics and antibacterial activity against E. coli and S. typhi. LAB characterization based on colony morphology, Gram staining, biochemical testing, coaggregation, and autoaggregation. Findings: There were 7 LAB isolates obtained, namely isolates with codes GNK1, GNK3, GNR2, GNR4, GUR1, GUR3, and GUR5. Isolate GUR3 can inhibit E. coli with the highest inhibition zone of 21.31 ± 3.98 mm. In the antibacterial test against S. typhi, 4 isolates had an inhibitory activity with the highest inhibition diameter by isolate GNK3 of 28.23±3.91 mm. LAB isolates from gatot have the ability to autoaggregate and coaggregate against E. coli and S. typhi. There are 5 isolates that show inhibitory activity against E. coli, namely GNK1, GNK3, GNR2, GNR4, GUR1, and GUR3. Inhibitory activity against S. typhi is shown by 4 LAB isolates, namely GNK1, GNK3, GNR2, and GNR4. Contribution: This research shows that LAB isolates from gatot have potential as probiotic agents with significant antibacterial activity against E. coli and S. typhi, so it can be developed as a natural alternative to control intestinal pathogens.

Abstract

Background: Robusta coffee rind (Coffea canephora) contains flavonoids, tannins, and phenolic compounds which are thought to have antioxidant activity. Flavonoids and tannins are compounds that have hydroxyl groups as reducers that can inhibit many oxidation reactions because they are able to donate an electron free radical compounds that function as antioxidants. This study aims to determine the value of the antioxidant activity of the robusta coffee rind extract and to determine the value of antioxidant activity in the preparation of a robusta coffee rind extract gel mask. The method used in the extraction is maceration using 96% ethanol with a yield value of 0,0655%. The results of the phytochemical screening test obtained flavonoids, phenolics, alkaloids, tannins and saponins. The antioxidant activity test of 0,00131%, 0,00262% and 0,00393% robusta coffee extract was carried out using the DPPH method and the IC50 values were 146.2 ppm, 136.7 ppm and 129.3 ppm, respectively. Gel masks are made at the best concentration of antioxidant activity, namely at a concentration of 6%. The 6% robusta coffee fruit skin extract gel mask has met the requirements of organoleptic tests, pH, homogeneity, dispersibility, cream type, adhesion and irritation. The antioxidant activity test of 6% robusta coffee rind extract gel using the DPPH method obtained an IC50 value of 170.40 ppm. The positive control for the mustika Ratu gel mask obtained an IC50 value of 73.15 ppm, and in the negative control an IC50 value was obtained of 386.6 ppm. The IC50 value parameter can be seen from the smaller the IC50 value, the higher the antioxidant activity value. Purpose: In order to know the formulation of the antioxidant gel mask preparation on the skin of robusta coffee berries (Coffea canephora). Method: The sampling technique used in the study used a simple random sampling method, namely sampling in a simple and random way. With UV-Vis spectrophotometry, mortar and stamper, beaker glass, steam dish, water bath, gel mask container, separating funnel, asbestos gauze, parchment paper, stirring rod, macerator, water bath, analyte scale, pH paper, blender, test tube , rotary evaporator, 10 and 50 mL measuring cups, volumetric flask, analytical balance, volume pipette, 250 mL erlenmayer, 1000 mL erlenmayer, cuvette, dropper pipette, 250 mL beaker glass, and oven. Results: smoothed sorting and obtained a dry weight of 315 grams. The percentage of drying shrinkage of the extract obtained was 60.62% as shown in Table 4.1. Conclusion: Test of 6% Robusta coffee fruit peel gel mask (Coffea canephora) has a moderate category of antioxidant with an IC50 value of 170.4 ppm.

Abstract

Butterfly pea blossoms (Clitoria ternatea L.) and Moringa leaves (Moringa oleifera) are purported to possess antibacterial properties. The antibacterial effectiveness is attributed to the potent active chemicals it possesses. One of the topical antibacterial agents is gel. Gel is a semi-solid formulation including colloids intended for external application. This research seeks to ascertain the feasibility of formulating a hand sanitizer gel utilizing a combination of butterfly pea flower extract and Moringa leaves, as well as to evaluate the antibacterial efficacy of this gel preparation against the proliferation of Escherichia coli bacteria. This research employed the maceration process utilizing a 96% ethanol solvent for extraction. The utilized extract concentrations are 1:1, 1:2, and 2:1. Each concentration of the gel formulation underwent a physical evaluation, followed by an efficacy assessment against Escherichia coli germs via the well diffusion method. The data were examined utilizing a one-way ANOVA test. The research findings indicate that the amalgamation of butterfly pea flower extract and Moringa leaves is suitable for hand sanitizer gel formulations, with formulations II and III receiving favorable evaluations. In the antibacterial efficacy test, formulation II demonstrated significant results with an average inhibition zone of 14.167 mm.
