Abstract

Manufacturing of prototype of plastics film for a biodegradable packaging from a mixture of polymer synthetic polystyrene (PS) and polycaprolactone (PCL) has been carried out. Plastics film containing of PS/PCL created by blending techniques followed by solvent casting, the ratios were 100/0, 95/5, 90/10 and 85/15. The resulting of plastic film is a clear sheet with an average thickness of 0.03 cm. The biodegradation rate profile was observed by soil burial test method to see the weight reduction of the plastic films tested for a certain period of time. The results showed that the biodegradation rate profile increased with the addition of PCL with the t50% in the 100/0, 95/5, 90/10 and 85/15 ratios respectively being 352.33; 91.19; 71.97 and 59.85 weeks, and t95% in the 100/0, 95/5, 90/10 and 85/15 ratios were respectively 677.01; 177.32; 139.43 and 115.79 weeks. Furthermore, the number of microbes present in each gram of soil is 1.83 x 105.

Abstract

Lipstick is the familiar product for women in difference age. Kind of lipstick that interested now is liquid lipstick. Not only it is cheap but also it can durable on lips. The actually using lipstick have to see of that safety from dangerous content like weight metal that content more than regulation. The objective of this research to know polluted metal content on some liquid lipsticks brand that they don’t registered in BPOM RI. Determine of standard metal on samples used spectrometry atom absorption (SSA) on facet 283.22 nm. The average metal content on sample a was 0.45999 PPM, sample B was 2.96333 ppm, and sample C was 0.62334 ppm. It can conclude that liquid lisptics have polluted on weight metal content but its content still fulfill of BPOM Standard is 20 µg/grs or 20 mgs/L

Abstract

Tomato is a kind of fruit containing vitamin C. Vitamin C is needed for collagen production, bone and teeth formation, wound healing, and immunity to infection. This vitamin is dissolve in water and easy to be destroyed by light and high temperature, so the storage and condition of tomato fruits need special attention to keep an adequate vitamin C level it contained. This research aimed to determine the level of vitamin C in three kinds tomato fruits maturation degree: raw, half-mature, and mature. The quantification was conducted using spectrophotometry UV-Vis method with maximum wave length of 265 nm and absorbance of 0.475 (Y=0.0557X + 0.0789). The result showed that the average level of vitamin C in raw, half-mature, and mature tomato was 74.03666; 53.81333; and 43.56666 mg/100g, respectively. In conclusion, the level of vitamin C in raw tomato was the highest among all samples.

Abstract

Telah dilakukan penelitian uji aktivitas antibakteri ekstrak daun senduduk terhadap Staphylococcus aureus. Daun senduduk mempunyai khasiat sebagai obat penurun demam, pereda nyeri, mengobati keputihan, diare, luka yang disebabkan oleh infeksi bakteri ataupun jamur. Salah satu penyebab infeksi pada luka adalah Staphylococcus aureus. Tujuan penelitian ini adalah untuk mengetahui dan menghitung zona bening yang diperoleh dari ekstrak daun senduduk terhadap Staphylococcus aureus. Ekstrak disuspensikan dalam Na CMC 0,5%. Ekstrak daun senduduk yang diuji adalah pada konsentrasi 20%, 25% dan 30%, klindamisin sebagai kotrol positif, dan Na CMC sebagai control hambat konsentrasi 20% dan 25% termasuk kategori resisten (≤16mm), dan konsentrasi 30% termasuk kategori intermediet 17-20mm.negatif. Penelitian ini menggunakan metode difusi agar dengan disk (cakram). Hasil penelitian didapatkan rata-rata zona hambat pada konsentrasi 20%, 25% dan 30% adalah: 15,1 mm, 15,9 mm, 20,5 mm, sedangkan pada kontrol positif sebesar 29,15 mm. Berdasarkan kriteria interpretasi untuk agen antimikroba menurut Coyle (2005), diameter zona
