Abstract

Latar Belakang: dalam analisis suatu zat kimia digunakan berbagai macam metode, salah satunya digunakan untuk penetapan kadar logam adalah kompleksometri. Metode ini didasarkan atas pembentukan senyawa kompleks antara logam dengan zat pembentuk kompleks (Na2EDTA). Seng merupakan salah satu logam yang membentuk senyawa kompleks dimana penetapan kadar seng menurut Farmakope Indoneesia edisi III ditetapkan secara kompleksometri menggunakan dapar amonia amonium klorida (pH 9-10). Sering kali dalam sedian farmasi ditemukan adanya kombinasi seng dengan vitamin C. zat ini merupakan vitamin dan mineral pelindung yang bersifat alamiah sebagai anti oksidan. Adanyaa vitamin C diperkirakan akan menurunkan pH campuran (lebih asam dibanding pH seng sulfat yang tanpa ditambah vitamin C. penelitian ini bertujuan untuk mengetahui pengaruh vitamin C terhadap ketelitian metode kompleksometri pada penetapan kadar seng sulfat.Populasi Penelitian: ZnSO4.7H2O dan serbuk vitamin C murni yangdiperoleh dari distributor bahan baku di Semarang. Metode yang digunakan adalah titrasi kompleksometri dan jenis penelitian ini adalah penelitian eksperimen.Hasil Penelitian: hasil penelitian adalah sebagai berikut; 1)Rekoveri sengsulfat dengan penambahan vitamin C: 0 mg, 100 mg, 150 mg, 200 mg, 250 mg, 300 mg, 350 mg, 400 mg, 450 mg, 500 mg, 550 mg berturut-turut adalah 100%, 98,67%, 98,28%, 98,24%, 97,78%, 97,57%, 97,19%, 96,77%, 96,45%, 95,82%, 95,46%; 2)Vitamin C yang masih dapat ditambahkan ke dalam seng sulfat sebanyak 550 mg dan kadar seng sulfatnya masih memenuhi persyaratan menurut Farmakope Indonesia yaitu 95 – 100%; 3)Metode Kompleksometri masih cukup teliti untuk digunakan pada penetapan kadar seng sulfat yang bercampur dengan vitamin C.Kata kunci: kadar seng sulfat, campuran seng sulfat dengan vitamin C,kompleksometri.

Abstract

The increasing numbers of small industries and home industries which processes food products are often tollowed by cases of chemical substances misuse. The process involves synthetic coloring substantive in order to get the expected product, for both for the producer andthe consumer.Jelly is a thick substantive made of seaweed. To make it, we only need to heat the jelly Jlour in boiling water, After it gets cold it will turn into gel and csn be formed the way we like it To add more Jlavors we can add natural or synthetic additional substances for coloring and sweetener onthe process.This research is dedicated to identify the types of synthetic coloring substantive added to jelliesand to compare the result with Permenkes RI No. 722 / PER / 1988.This is a descriptive research, using chromatograph paper method to check the qualitative test on the synthetic coloring substantive used. Population of the research is the jellies sold at Pasar Doro Pekalongan, with 4 (four) out of 5 (ive) colors taken as the sample purposively from each packages sold there.The data is taken from laboratory test, and conveyed in descriptive way. Result on laboratory test on jellies sold at Pasar Doro Pekalongan is that they uses Eritrosin, Green S, Sunset Yellow, Tartrazin, and Carmoisin as the synthetic coloring substantives as stated in Permenkes RI No.722 / MENKES / PER/ IX/ 1988.Keywords : synthetic coloring substantive, jelly, paper chromatograph.

Abstract

Abstract Background: Tooth paste is one of the cosmetics product used not only by adult but also children. The Function is to clean teeth from food or beverages scrap, to keep the health of teeth and gum, and also to reduce the smell caused by mouth bacteria. Tooth paste is made from several ingredients; among other is the surfactant that can form foam from toothpaste. Surfactant is usually added in a form of synthetic detergent because it can give fictive foaming effect in a form of anionic detergent. The use of surfactant in tooth paste is low spread and to wet the particles found in tooth paste. The surfactant has to be able to create liquid Suspension from the polishing materials during the process of brushing the teeth and make it able to dissolve into the pit of teeth in order to accelerate the cleaning effect and getting rid the unknown substances. Some other surfactant can also lower the surface pressure in order to make toothpaste absorb into the teeth surface Pores and fictively dissolving the dirt attached to the teeth. According to Harry's Cosmeticologt, the amount of surfactant allowed in tooth paste is around l%-2%. Population o/ the Research: The sample used in this research is the children's toothpaste taken using the random sampling method out of various brands and flavors. Each simple is analyzed using triple method. Result of the Research: The result of the research is as shown: l) Anionic detergent amount found in Children toothpaste sample A = 0,15%o, sample B = 0,06%, sample C = 0,04%, sample D = 0,050%, sample E =0, 13%, sample F=0,30%,sampleG=0,35%,sampleH=0,lToldansamplel=0,28%. 2)Anionic detergent amount found in children tooth paste being researched fulfill the Harry's Cosmeticologt criteria that says the amount of anionic detergent or surfactant found in toothpaste should not be more than 2%o. Keywords: analysis on amount, anionic detergent, children's Tooth paste
