Abstract

This study focuses on the development of a natural deodorant spray to address body odor caused by bacterial activity in sweat. The formulation utilizes alum, basil leaf extract, and lemon extract, all known for their antibacterial properties. Three formulations were evaluated: F1 (alum and basil extract), F2 (alum and lemon extract), and F3 (a combination of all three). The formulations underwent physical testing, pH analysis, clarity assessment, skin irritation evaluation, and fabric compatibility tests. Results indicated that F1 demonstrated stability in pH and clarity, F2 offered a superior aroma, and F3 exhibited the strongest antibacterial efficacy with a balanced fragrance. All formulations were found to be non-irritating and safe for use. The combination of these natural ingredients demonstrates significant potential for producing eco-friendly and consumer-safe deodorant spray products, highlighting their effectiveness in combating body odor while maintaining user comfort and environmental sustainability.

Abstract

The rapid expansion of oil palm plantations in North Sumatra, from 31,730,961 hectares in 2016 to 41,667,011 hectares in 2018, has resulted in significant solid waste generation, particularly empty fruit bunches (EFB). This study aims to utilize EFB as a precursor for activated carbon production and evaluate its effectiveness in adsorbing beta-carotene from crude palm oil (CPO). EFB was processed through carbonization and activation to create a composite adsorbent KA-Fe(TAC) synthesized with metal-organic frameworks (MOFs). Characterization using X-ray diffraction (XRD) confirmed the crystalline structure of the composite. Results indicated that the optimal adsorption efficiency for activated carbon was 8.925%, while the KA-Fe(TAC) composite achieved 21.645%. The findings suggest that the KA-Fe(TAC) composite significantly enhances beta-carotene adsorption capacity compared to conventional activated carbon. Additionally, the optimal contact time for adsorption was found to be 60 minutes for activated carbon and 150 minutes for the KA-Fe(TAC) composite, indicating improved efficiency over time.

Abstract

This study aims to evaluate the effectiveness of various combination of adsorbents in reducing salt content in seawater through the adsorption method. Four variations in the ratio of adsorbent materials, namely activated charcoal, silica sand and palm fiber, were tested with different amounts. activated charcoal, silica sand, and palm fiber, were tested with different amounts. Results showed that the 1:2 ratio (800 grams of activated charcoal and 400 grams of silica sand) resulted in a decrease in salt content from 20% to 3%, which was the highest reduction compared to the other comparison. In addition, the pH test showed that the pH value of the water after the adsorption process remained in the neutral range, namely 7 to 7.5, which indicating that the filtration process successfully improved the water quality. This study indicates that the use of local materials such as activated charcoal and silica sand can be an effective and environmentally friendly solution to reduce the effective and environmentally friendly solution to reduce seawater salinity, as well as increase public awareness of the importance of clean water. public awareness of the importance of clean water. These results are expected to contribute to the development of a more affordable and sustainable desalination technology. technology that is more affordable and sustainable.

Abstract

The research focuses on improving the structure and quality of activated carbon by synthesizing porous polymers or Metal-Organic Frameworks (MOFs). Characterization of AC-Cu(TAC)2 and AC-Fe(TAC)3 is carried out using XRD, SEM, and EDX instruments. Characterization of AC- Cu(TAC)2 and AC-Fe(TAC)2 revealed that the observed XRD pattern is representative of the structure of crystalline materials, with AC-Cu(TAC)2 and AC-Fe(TAC)3 having a crystallinity of 40% with both materials forming a triclinic crystal system. Characterization based on SEM at 200x magnification shows that the fibers are interbonded and attached to the cross-section on AC- Cu(TAC)2 , having a relatively large porosity so that it shows a fairly strong bond between activated carbon and Cu(TAC) MOFs. the size of the fragmented fiber particles in AC-Fe(TAC)3 which is relatively not the same as the smaller porosity. EDX characterization shows that Cu and Fe metals are one of the composite materials.
