Biscuits Feed Forage is obtained by the technique Silage. These biscuits can be made from agricultural waste including corn waste. As one of the agricultural centers in West Sumatra, corn production in the District Batusangkar very high. However, agricultural production is not followed by the management of agricultural waste are mostly just burned. The purpose of the study was to test to make biscuits forage from corn waste using techniques silage accompanied with the addition of nutrients, the test mold making biscuits conventionally made using the technique of pressure, conducting organoleptic test and analysis proximate to product biscuit feed forage already made. The results were obtained from waste animal feed forage of good quality corn silage by using the technique. treatment P2 (corn leaves 1 kg + 5% + molasses urea 10%) and T1 (1minggu after harvest). Green feed made with the best formula is packaged in the form of biscuits using conventional printing equipment.

The purpose of this research is to study the effect of bismuth films in the determination of arsenic. In this study, the addition of bismuth ions with a concentration of 200 ppb. Voltammograms can be seen from quite a significant difference between the peak current generated by As (III) films coated with a non-bismuth bismuth films. Visible peak current of As (III) is higher if the addition of bismuth films. This proves the statement Nagaosa, et al who stated that there are mixed effects of bismuth in the determination of As (III) although the mechanism remains unclear.</p><p style="margin: 1em 0px; color: #111111; font-family: Arial, Verdana, Helvetica, sans-serif; font-size: 11.2px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: #fafafa;">Keyword: film bismuth, arcenic, differential pulse, anodic, stripping voltammetry</p>

Because of the tendency found in water use rechargeable (AMIU) by society, especially in urban areas, especially cities Batusanggkar increasing. However, the quality still needs to be studied in order to secure the quality of drinking water that directly affect public health, the course of a study of drinking water quality testing that has been done in District Batusangkar The limo showed that 9.1% of drinking water depots produce drinking water quality does not meet the requirements biological parameters (microbiological) that has been set by the government through Permenkes. 492 of 2010 on drinking water quality requirements, while for Physical parameters (temperature) and chemical parameters (pH) has met the requirements of the government.</p><p style="margin: 1em 0px; color: #111111; font-family: Arial, Verdana, Helvetica, sans-serif; font-size: 11.2px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: #fafafa;">Key words: drinking water,<span class="Apple-converted-space"> </span><em>Escherichia coli<span class="Apple-converted-space"> </span></em>, temperature, ph</p>

These are of environment media that needs reaserched to know how far the radioactivity level. This was done at environment laboratory of PTKMR-BATAN. Step of reaserch has been done as follow determining the location and take the samples, cultivating the samples in laboratory, measuring the samples with LBC and samples analysis. From the result of measurement it shown that the lowest concentrate could be measured by LBC device that was 0,093 mBq/Kg. Sr-90 concentrate into the result of reaserch shown the data with variation from undetected data (0,4749 ± 1,1422)mBq/Kg. Activity concentration Sr-90 which was found in the plants of agriculture result in West Sumatera land are the low than Java island area and lower than found in Japan.</p><p style="margin: 1em 0px; color: #111111; font-family: Arial, Verdana, Helvetica, sans-serif; font-size: 11.2px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: #fafafa;">Key words: environment media, radioactivity level, LBC.</p>
