Abstract

Waste cooking oil has been repurposed in the preparation of liquid hand soap, enriched with Aloe vera extract as an antibacterial agent. To ensure the safety and efficacy of the product in bacterial inhibition, comprehensive testing of physical quality and antibacterial activity has been undertaken on the produced liquid soap. The test results affirm that the soap product complies with the Indonesian National Standard for free alkali content, acidity level (pH), foam height, foam stability, and water content. Notably, the soap exhibits a free alkali content of 0.01873%, a pH of 10, a foam height of 65 mm, and a foam stability value of 84.61%. The water content in the soap is measured at 40%. These results collectively position the soap within the criteria for high-quality soap. In the antibacterial effectiveness test against Staphylococcus aureus and Escherichia coli bacteria, the addition of Aloe vera has markedly expanded the inhibitory zone, demonstrating a significant enhancement in antibacterial activity. In light of the above, this study aims to address environmental pollution and health risks associated with improper disposal of waste cooking oil. Moreover, the addition of antibacterial Aloe vera presents an economically valuable solution by repurposing waste cooking oil into a useful product.

Abstract

Abstract The earthquake that struck the Cianjur region had an impact on the economic resources and income of the community, including those in the Sawah Gede neighborhood. This natural disaster affected the crucial sectors of the community's economic activities, indirectly leading to a decline in the economic performance of the area. However, when viewed from a positive perspective, this natural disaster actually has the potential to trigger new economic growth in the region. The emergence of new economic growth can be facilitated, in part, by the establishment of small home-based industries. One option that the community can consider is the production of soap using used cooking oil as a raw material. This potential is substantial, given the high consumption of cooking oil by the community, which is directly proportional to the increase in the amount of used cooking oil waste generated. This business opportunity not only contributes to the growth of the community's economy but also educates the public about environmental conservation. This Community Service Program (PKM-KKN) is implemented as an effort to empower the community's economy through the production of liquid hand soap. This involves various stages, including the manufacturing process, product packaging, and product promotion. Abstrak Gempa bumi yang melanda wilayah Cianjur berdampak pada sumber ekonomi atau pendapatan masyarakat, Salah satunya masyarakat di kelurahan Sawah Gede. Bencana alam ini berdampak pada sektor penting kegiatan ekonomi masyarakat, yang secara tidak langsung berimplikasi pada penurunan kinerja perekonomian wilayah tersebut. Namun, jika dilihat dari sisi positifnya, bencana alam justru berpeluang dapat memicu pertumbuhan ekonomi yang baru di wilayah tersebut. Pertumbuhan ekonomi baru dapat dibentuk salah satunya dengan menciptakan industri kecil rumahan. Salah satu opsi yang dapat dipilih masyarakat adalah industri pembuatan sabun berbahan baku minyak jelantah. Potensi ini cukup besar mengingat konsumsi minyak goreng masyarakat yang tinggi dan berbanding lurus dengan peningkatan jumlah limbah minyak goreng yang dihasilkan. Peluang usaha tersebut tidak hanya berpengaruh pada meningkatnya pertumbuhan ekonomi masyarakat tetapi juga mengedukasi masyarakat untuk turut menjaga lingkungan. Kegiatan PKM-KKN ini dilaksanakan sebagai upaya dalam pemberdayaan ekonomi masyarakat melalui pembuatan sabun cair cuci tangan, kemudian pengemasan produk hingga promosi produk.

Abstract

SnCoNi catalysts were synthesized via electrodeposition, with and without citric acid, to assess their ethanol electrooxidation performance. The additive-free catalyst exhibited superior properties, including lower charge transfer resistance and a smaller Tafel slope compared to the citric acid-modified catalyst. Chronoamperometry testing further revealed better electrochemical stability for the additive-free catalyst, with less current loss over time. Cyclic voltammetry confirmed the enhanced ethanol oxidation activity with a relatively high current density. The improved performance is attributed to better mass transport, active site exposure, and the synergistic effects of Sn, Co, and Ni in the additive-free catalyst, making it more efficient for ethanol electrooxidation. These findings suggest that the additive-free catalyst exhibits more favorable properties for ethanol electrooxidation compared to its citric acid-modified counterpart.
