Abstract

Hand soap is one of the means to clean hands from dirt, germs and other things that make hands dirty. To kill bacteria, some hand soaps contain active substances that can have a negative effect on humans who have sensitive skin, which can cause irritation. Some synthetic active ingredients that are harmful to human skin health are diethanolamine (DEA), Sodium Lauryl Sulfate (SLS), and triclosan which functions as an antibacterial. This study aims to obtain the composition of basil leaf extract with the right maceration time as an antibacterial and can produce liquid hand soap products that are in accordance with the quality of SNI 2588:2017 by varying the composition of the basil leaf extract and varying the maceration time. Variations in the composition of basil leaf extract are 3%, 6%, and 9% as well as variations in maceration time of 3 days and 7 days. Analysis of liquid hand soap products includes pH, insoluble in ethanol, free fatty acid content, surface tension, organoleptics, and bacteria. Based on the results of the analysis, all samples met the quality of SNI, but the sample with the best formulation of liquid hand soap was obtained at a composition of 9% extract (9 ml of basil leaf extract in 100 ml of soap volume) with a maceration time of 7 days. The results of the analysis showed that the resulting pH value is 8, the material is insoluble in ethanol 0.46%, free fatty acids 0.32% and the surface tension of soap is 13.52 dyne/cm.

Abstract

Various types of bacteria, viruses and fungi will be easier to stick to and thrive on unclean hands. Making people use products that contain antiseptics such as soap and hand sanitizer. However, in general, the basic ingredient for making antiseptics comes from alcohol. The development of antiseptic products can be done with natural ingredients such as using sweet orange peel (Citrus sinensis (L.)). It is known that sweet orange peel (Citrus sinensis (L.)) contains saponin, flavonoid, and tannin compounds which act as antibacterial so that it can be a natural antiseptic ingredient for making hand sanitizer gel. This study aims to determine the effect of maceration time and composition of sweet orange peel extract on antiseptic power in hand sanitizer gel preparations and can produce hand sanitizer products that are in accordance with SNI quality by varying the maceration time of the extract, namely 3 days, 5 days and 7 days the amount of sweet orange peel extract 5%, 10% and 15%. The product analysis of hand sanitizer gel includes organoleptic, homogeneity, pH, density, viscosity, dispersibility and bacteria. Based on the results of the analysis, all samples met the quality of SNI, but the best sample was 15% composition with a maceration time of 7 days. The results of the analysis showed that the pH value was 6, the density was 1.0470 gr/cm3, the viscosity was 578.08 cP, the dispersion was 8.3 cm.

Abstract

Aktivitas utama pabrik kelapa sawit dimulai dari penanaman dan pemanenan pohon kelapa sawit, pengolahan tandan buah segar (TBS) menjadi minyak sawit (CPO) dan inti sawit (PK), hingga memprosesnya menjadi produk industri. Tanah dan tanaman merupakan dua hal yang sangat penting dalam bidang pertanian. Untuk menghasilkan buah kelapa sawit yang berkualitas tinggi, tanaman harus mempunyai unsur mineral yang cukup seperti unsur hara makro dan mikro. Sampel yang digunakan untuk analisis kandungan unsur kalsium (Ca), tembaga (Cu), kalium (K), dan magnesium (Mg) adalah daun kelapa sawit yang bersumber dari salah satu perkebunan kelapa sawit di daerah Riau. Hasil analisis kandungan unsur pada daun kelapa sawit yaitu unsur kalium (K) sebesar 1,64–2,16 ppm, unsur magnesium (Mg) sebesar 0,46–0,79 ppm, unsur kalsium (Ca) sebesar 1,51–2,11 ppm, dan unsur tembaga (Cu) sebesar 0,07–0,14 ppm. Hasil penelitian ini menunjukkan bahwa kandungan unsur yang terdapat pada daun kelapa sawit tersebut belum mencukupi untuk proses pertumbuhan kelapa sawit, karena kandungan unsur tersebut masih tergolong rendah. Sehingga untuk mengatasi defisiensi unsur hara tersebut, dilakukan pemulihan dengan penambahan pupuk pada tanaman. Hasil analisis unsur di atas dapat digunakan sebagai dasar pemilihan pupuk yang sesuai serta berapa kadar yang dibutuhkan yang harus diberikan pada tanaman kelapa sawit.

Abstract

The peel and seeds of tamarillo (Solanum betaceum Cav.) are sources of anthocyanin pigments with potential application as natural dyes for a more environmentally friendly textile industry. The widespread use of synthetic dyes, which still dominates today, poses negative impacts on both the environment and human health. Therefore, this study was conducted to evaluate the quality of the resulting extracts. The parameters assessed included acidity level (pH), anthocyanin content based on UV-VIS absorbance values, color characteristics, and color fastness in accordance with the SNI ISO 105-A03:2010 standard. The results showed that the duration of maceration had a significant effect on the quality of the extracts. For the peel extract, the optimal condition was obtained at pH 3, with an anthocyanin content of 65.12 mg/L, an absorbance value of 0.391, and color fastness at a scale of 4–5, which is categorized as very good. Meanwhile, the seed extract exhibited optimal results at pH 3, with an anthocyanin content of 127.07 mg/L, an absorbance value of 0.761, and color fastness at a scale of 4, which falls under the good category. Overall, these findings indicate that tamarillo peel and seeds have significant potential as a sustainable source of natural textile dyes and can serve as a safer alternative to synthetic dyes.
