Eggs consumed by many people because it’s easily to processed, low cost, and have perfect substances, especially proteins. The purpose of this research were to determine levels of the protein in the fowl’s eggs. The sample used in this research are rooster chicken egg, ayam kampung egg, duck egg, and quail egg. The protein content in fowl’s eggs were evaluated using Kjeldahl method by calculating the total nitrogen content and converted (conversion factor is 6.25). Result of the research protein content contained in rooster chicken egg 6.4506 % ± 0.1418, ayam kampung egg 6.9102 % ± 0.0475, duck egg 6.5996 % ± 0.0497, and quail egg 6.5532 % ± 0.0110. The result of the test statistics clarify that the sample eggs are examined to contain the protein with the levels of different significantly (F = 94.461 and sig. 0.000 (<0.05)). Where ayam kampung egg have protein content higher than another eggs sample and the lowest protein content contained in rooster chicken egg.

A Research has been done about preparing calcium carbonat from limestone of Bukit Tui Kota Padang Panjang. The sample as much as 20 g was dissolved in HCl 6 M, the resulting filtrate reacted with NH4OH 6 M to the pH of 8 and reacted with (NH4)2CO3 6 M until no more precipitate was was formed. The precipitate was separated and dried in oven for 4 hours at 105º C. Ten g of the dried precipitate was determined complexometrically using EDTA as complexson and murexide as indicator. It was found that the limestone at Bukit Tui Kota Padang Panjang contained 67.2 % w/w calcium carbonate in comparison to reference compound 103.99 % w/w.

The study about analysis of preservative sodium nitrite in beef by Spectrophotometry method has been done. The study was conducted by using which obtained from two supermarket and three traditional markets in Padang city, there are samples A, B, C, D and E. The levels of sodium nitrite in beef was determined by qualitative and quantitative analyzing. The result showed that preservative sodium nitrite found in samples A and B, which levels in samples A was 11,325 mg/Kg and samples B was 0,575 mg/Kg. While sodium nitrite was not found in samples C, D and E. It can be concluded that the levels of sodium nitrite in samples A and B are comply with requirements of Regulation of The Head of The National Agency of Drug and Food Control of Republic Indonesia No. 36 year 2013 which is concerning about food additives, which levels of preservative nitrite is maximum of 30 mg/Kg.
