Abstract

Pemanfaatan sampah rumah tangga seperti sampah dapur dapat dilakukan dengan sederhana menggunakan prinsip 3R (Reduce, Reuse dan Recycle). Selain itu, salah satu produk dari pemanfaatan sampah rumah tangga adalah Eco-Enzyme. Eco-enzyme merupakan larutan hasil fermentasi sisa bahan organik (buah dan sayuran), gula dan air. Kegiatan pengabdian masyarakat yang dilakukan di Posyandu Kelurahan Padasuka adalah edukasi pemanfaatan sampah rumah tangga dan pelatihan pembuatan Eco-Enzyme. Kegiatan ini diikuti oleh Tim DAHSAT Kelurahan Padasuka, Ciomas, Bogor sebanyak 21 orang di Posyandu Anugerah, Kelurahan Padasuka, Ciomas, Bogor. Materi edukasi diberikan dengan metode ceramah dan diskusi menggunakan media leaflet. Persentase peningkatan nilai post-test pada peserta yang mengikuti kegiatan edukasi yaitu sebesar 88.2%, dimana terjadi peningkatan nilai post-tes sebanyak 27 poin. Pelatihan pembuatan eco-enzyme dilakukan dengan setiap peserta praktek langsung membuat eco-enzyme dari sampah dapur yang dibawa oleh peserta. Pembuatan Eco-Enzyme dapat menjadi salah satu alternatif pemanfaatan sampah rumah tangga dari sisa makanan/bahan dapur sehingga bisa lebih bermanfaat dan memiliki daya jual.

Abstract

Betel leaf (Piper betle L) is a plant that is commonly found in Indonesia. It is known that green betel leaf contains ingredients that act as antiseptics consisting of cavibetol, sesquiterpenes, hydroxy kavikol, carvakrol, estagiol, terpenes, phenylpropane, tannins and eugenol methyleugenol. Essential oils which contain phenol which is one of the antibacterial substances. The purpose of this study was to determine the effect of betel leaf extract on pH and microbial properties of antiseptic gel. The initial stages of this research are the extraction process of betel leaf with 70% ethanol solvent with time variations of 5 minutes, 10 minutes, 15 minutes, 20 minutes, and 25 minutes. Furthermore, each time variation is calculated yield results. The best yield was added to the antiseptic gel then analyzed for pH and tested for its inhibitory power as an antiseptic against Staphylococcus Aureus. Based on the research results, the yield of betel leaf extract with time variables of 5, 10, 15, 20, 25 minutes in a row are: 83.47%; 83.99%; 86.48%; 86.76%; 87.34%. In pH testing the results obtained pH 5.5. In the inhibition test, the results obtained successively, namely 18.23: 19.70: 18.82: 19.98 mm.

Abstract

The utilization of purple sweet potato (Ipomoea batatas var. Ayamurasaki) as a natural antioxidant agent in emulgel cosmetic formulations offers potential for developing effective facial skincare products. The anthocyanin pigments contained in purple sweet potato were extracted via the reflux method using 70% ethanol, yielding a 13% extract. The total anthocyanin content was measured at 26.72 mg/100g wet weight, providing potent antioxidant activity with an IC₅₀ value of 10.77 ppm. Various extract concentrations (F1–F6) incorporated into the emulgel base demonstrated physical characteristics that met cosmetic standards, including excellent homogeneity and a stable pH range between 5.3 and 6.8. The evaluation of antioxidant activity revealed a positive correlation between increasing extract concentration and the effectiveness of free radical scavenging. Formula F6 yielded the most optimal antioxidant activity with an IC₅₀ value of 8.39 ppm. These emulgel face mask preparations proved to be physically stable and possess significant skin protection potential against oxidative stress. Purple sweet potato is verified as a viable natural active ingredient for topical product formulation, providing functional added value for the development of nature-based cosmetics.

Abstract

This study investigated the effectiveness of coconut shell–derived liquid smoke (CLS) and activated carbon–treated liquid smoke (CLSC) as natural coagulants for natural rubber latex clone PB 260, compared with 2% formic acid (FA). Rubber quality was assessed based on Total Solid Content (TSC), Dry Rubber Content (DRC), initial plasticity (Po), Plasticity Retention Index (PRI), ash content, dirt content, volatile matter, and Mooney viscosity according to the SNI 06-1903-2017 standard for Indonesian Standard Rubber (SIR 20). Experiments were conducted using fresh latex from clone PB 260 under the D3 tapping system, with 150 mL of latex treated with each coagulant. FA produced the fastest coagulation time (3.39 min), while CLS and CLSC required 4.37 and 4.29 min, respectively. CLS showed the highest DRC (15.33%), whereas CLSC provided better rubber stability with the highest PRI (85.83%) and high Mooney viscosity. All coagulants met SIR 20 limits for ash, dirt, and volatile matter, although Po values remained below the standard.
