Abstract

Soap is a type of cleaning product that is used to clean dust, oil, dirt, germs, and bacteria that stick to the skin. Ginger is a plant that contains a wide range of antibacterial compounds including E. Coli, Staphylococcus aureus, B. Cereus, L monocytogenes and Candida albicans bacteria. Soap is made by chemically reacting sodium or potassium compounds with fatty acids derived from vegetable oil or animal oil. This study aims to determine the physical characteristics of solid soap with ginger rhizome extract with a combination of coconut oil and palm oil and analyze the panelist’s response to the soap produced. In the third week of observation, it is known that the water content ranges from 0,07%-0,1% with foam stability 71,11%-88,23% and pH 8,96-9,08. The most preferred solid soap based on the response of the panelist is soap from a mixture of coconut oil and palm oil with a ratio of 15:5.

Abstract

Terasi biasa diberi pewarna merah agar lebih menarik. Tahun 2013, pernah ditemukan Rhodamin B dalam produk terasi yang beredar di pasar kabupaten Sumbawa Barat. Rhodamin B adalah pewarna merah yang dilarang digunakan untuk makanan. Diantara berbagai produk terasi yang dijual di Sumbawa, terasi khas asli Sumbawa yaitu terasi Empang, perlu dijaga keamanannya agar dapat lebih dipromosikan. Tujuan penelitian ini adalah membuktikan bahwa terasi yang dijual pasar kota Sumbawa Besar tidak mengandung Rhodamin B. Metode yang digunakan untuk identifikasi Rhodamin B adalah kromatografi lapis tipis (KLT). Penelitian ini menggunakan silika gel 60 F254 sebagai fase diam dan fase gerak terpilih yaitu N-butanol:etil asetat:amonia 25% (10:4:5). Sampel adalah produk terasi yang dijual di Pasar Kota Sumbawa Besar, periode sampling bulan Februari dan Maret 2021. Preparasi sampel terasi dengan cara diekstraksi menggunakan etanol dan volume ekstrak yang ditotolkan pada lempeng KLT adalah 2 μl. Parameter validasi metode yang diuji adalah spesifisitas/selektifitas dan batas deteksi (LOD). Hasil penelitian menunjukkan metode ini spesifik untuk Rhodamine B yaitu Rf 0,69, profil spektra yang sama antara baku dan sampel yang diadisi Rhodamin B. Resolusi (Rs) antara noda Rhodamin B dengan noda terdekat lain dalam sampel adalah >1,5. Panjang gelombang serapan maksimum Rhodamin B adalah 544 nm. Nilai LOD sebesar 4,14 ng. Hasil identifikasi terhadap 10 sampel yang terdiri dari 3 sampel terdaftar di BPOM dan 7 sampel tidak terdaftar di BPOM tidak terdeteksi adanya Rhodamin B. Kesimpulan dari penelitian ini adalah semua sampel terasi yang dijual di pasar kota Sumbawa Besar tidak terdeteksi mengandung Rhodamin B.

Abstract

Borax, in illictic additive substance, is added on certain food product as a e preservative and rubbery. Therefore, the determination of borax in the food product such as meatball is very impotant in view of meatball is a food product often consumed by community. Vis- Spectrophotometric method with curcumine 0.125% as a reagent and glacial acetic acid-sulphuric acid has been used for determination of borax in this research. Curcumin reagent was selected because sensitivity of the method and the reproducibility of the results are affected by quality of the reagent other than rigorous observance of the reaction conditions (temperature, time, reagent quantities). Glacial acetic acid- sulphuric acid was used to create acid condition, so that curcumin and boron form a violetred 2:1 complex called rosocyanin. The optimum result was obtained when 1/. ml solution of 0.125% curcuumin and 1.0 ml concentrated sulphuric acid were added and the absorbance was measured after 70 minutes at 547 nm. The results showed linear regression y = 1.3127x – 0.0994, r = 0.9690 > r table (n = 5) is 0.878 and p = 0.007 (p< 0.01) and Vxo is was 15,53%. The detection limit and quantitation limit were 9.7.10-4 ppm and 2.94. 10-3 ppm respectively. The recovery and coefficient variation were 47.56%±3,92%. Determination of borax in three meatball samples which were taken from a location in Surabaya showed that the sample contained borax with concentration of 0.0205; 0.0151; 0.0210 (% w/w) respectively.

Abstract

Lopinavir and ritonavir are anti-viral compounds that have similar chemical structures and overlapping UV spectral profiles. The combination of these two compounds is being promoted as an anti-COVID19 drug. Determination of these two compounds simultaneously using UV spectrophotometry method requires special technique so that the result will be valid. The purpose of this study was to obtain a suitable analytical technique using UV spectrophotometry for the determination of lopinavir-ritonavir simultaneously that fulfill the method validation requirement. In this study, the simultaneous equation technique, absorptivity comparison factor, and first derivative technique were used to overcome the effect of lopinavir/ritonavir absorbance at selected wavelengths for determination of each compound simultaneously. The one-way ANOVA statistical test was used to compare the result of the three analytical techniques. The results showed that the three techniques fullfilled the AOAC requirements for selectivity and linearity. The accuracy and precision test result have not met the requirements of the AOAC method validation. Statistically. the one-way ANOVA analysis showed there was a significant difference between the mean recovery of lopinavir using the absorptivity factor and first derivative technique. Whereas, there was no significant differences among the mean of ritonavir recoveries that were determined using those three techniques. As conclusion, that the UV spectrophotometric method using the simultaneous equation technique, the absorptivity factor technique, and the derivative technique for assaying the lopinavir and ritonavir simultaneously met the requirements for selectivity and linearity parameters. However, the accuracy and precision have not met the requirements. The first derivative technique is suitable for further developed for ritonavir and lopinavir determination simultaneously

Abstract

The main ingredients of roselle (Hibiscus sabdariffa L.) which have antioxidant and antibacterial effect were anthocyanins, and flavonoids. Flavonoid compounds were unstable at high temperatures. Meanwhile, the processing of roselle extract powder into ready-to drink or food preparations generally requires the thermal processes. The aims of this study were to determine the effect of temperature and heating time of roselle extract powder solution on the inhibition of microbial growth of Staphylococcus aureus ATCC 25923. The method of this study uses a ready-to- process roselle powder extract sample. The roselle extract powder solution in a screw cap tube was heated at a temperature of 40°C, 50°C, 60°C, 70°C, 80°C, and 90°C on a waterbath, with heating times at each temperature were 15 minutes and 30 minutes. Anti bacterial activity of the sample solution was measured based on the ability to inhibit the growth of Staphylococcus aureus ATCC 25923 by the agar-well diffusion method. The inhibition zone of the sample was measured by caliper. The result of this study showed that inhibition zones caused by the sample that had been heated at those temperature for 15 minutes were 9.55±0.70 mm, 9.53 ±0.04 mm, 9.70±0.14 mm, 9.68±0.24 mm, 10.10±0.14 mm, and 10.25±0.21 mm. Meanwhile, after heating for 30 minutes the inhibition zones were 10.08±0.25 mm, 10.20±0.28 mm, 10.43±0.18 mm, 10.08±0.18 mm, 10.78±0.04 mm, 9.70±0.14 mm. Two ways statistical test ANOVA Randomized Control Block Design with 95% confidence level was used to prove that there was a significant difference berween the mean inhibition zones of each sample. The conclution of this research was, the temperature in the range of 40 -90 oC has no effect on the anti-bacterial activity of the sample. However, the heating time of the sample affected the antibacterial activity of the roselle extract powder solution against Staphylococcus aureus ATCC 25923.
