Abstract

Busy activities and high rainfall can quickly get shoes dirty, so an instant and rinse-free shoe cleaner is needed. This instant shoe-cleaning innovation without rinsing can utilize sunkist coconut fiber and orange peel waste, which are abundant. The coconut husk waste is processed into ash, and its potassium content is extracted as a polish and alkaline source. The sunkist orange peel undergoes citric acid extraction using the maceration method, which can potentially be an antibacterial agent. Five formulations of foamtastic are made with various compositions. Each formulation is tested for cleaning power against various stains, antibacterial properties, foam height, and stability. Formulation 4 is the best formulation based on optimal cleaning power, antibacterial properties, foam stability, and safe and effective pH for use as a cleaning product. Keywords: Formulation, Sunkist orange peel, shoe cleaner, coconut fiber

Abstract

One of the graduation requirements for students at the IPB University Vocational School is to have an Administrative Free Certificate. The letter is a unified approval from all Persons in Charge of the Laboratory and Library of SV IPB which explains that the student does not have a loan and is not receiving disciplinary sanctions from the Discipline, Student Affairs and Alumni Commission. The large number of prospective graduates every year causes a long queue in making the Certificate of Administrative Freedom if the submission is done manually to each Person in Charge of the Lab. The purpose of this research is to develop the IPB Vocational Lab Information System (SILVI) by adding an Administrative Free Module. The methodology used in this study is the Prototype Method. The stages carried out in the prototype method are communication, quick plan, modeling quick design, construction of prototype, and deployment delivery & feedback. Based on the feasibility test of the system, 100% of the features run without any errors, so it can be concluded that SILVI can be used properly.

Abstract

The green synthesis of silver nanoparticles (AgNP) presents notable benefits, such as environmental sustainability, simplicity, cost-effectiveness, and scalability for industrial applications. This study utilized green tea leaves (Camellia sinensis), which are abundant in catechins and polyphenols, as natural reducing and stabilizing agents. Ultrasonic-assisted synthesis was utilized to improve extraction and reduction processes, as acoustic cavitation induced by ultrasonic waves facilitates efficient mass transfer, accelerates nucleation, and enhances nanoparticle dispersion. This method provides an environmentally sustainable and economically viable alternative to conventional AgNP synthesis, enhancing the sustainability of nanoparticle production. The successful synthesis of AgNP was evidenced by the distinct color change of the tea extract from green to brown, accompanied by the formation of a brown colloidal suspension, in accordance with the Surface Plasmon Resonance (SPR) phenomenon. The UV-Vis spectrophotometric analysis confirmed AgNP formation, evidenced by a characteristic absorption peak at approximately 430 nm. The synthesized AgNPs were utilized as a colorimetric sensor for Fe³⁺ ions in aqueous solutions, demonstrating distinct color changes and SPR band shifts upon interaction with the metal. This illustrates their capability as environmentally friendly nanomaterials for the swift and precise detection of heavy metals, aiding in sustainable environmental monitoring. This research integrates ultrasonic-assisted synthesis with green tea extract, presenting a viable approach for the large-scale, environmentally sustainable production of nanoparticles.
