Abstract

Processing market waste into feed can increase the added value of waste. Market waste consisting of vegetables and animals still contains nutrients that are beneficial for livestock and fish as an alternative or main feed. Utilization of market waste into fish pellets needs to be studied with a fermentation process with variations in fermentation time of 2-6 days, molasses content (5%, 10% and 15%) and animal and vegetable composition (1:1, 2:3 and 3:1) on crude protein and feed quality. The process of making feed by mixing market waste materials and a fermentation and flouring process will be carried out to obtain uniform pellets in printing. Protein test will be carried out using the Kjedhal method as crude protein content. Based on the results of buoyancy for more than 6 minutes, pellets with a composition of 50% fish offal had the best quality compared to other variations with a protein content of 32.48%.

Abstract

A lot of limestone encountered in Indonesia. Most of the limestone reserves in Indonesia are in West Sumatra. Limestone utilization in West Sumatra is currently only limited as the adhesive mortar or bleach on the walls, so that the low economic value. Therefore, the need for efforts to increase the value added products of limestone, which is to process it into products that are more efficient in the industry such as precipitate calcium carbonate (PCC) which has a high economic value. PCC is a limestone that has been processed in such a way so as to form small particles that homogeny and it’s easy to set up. Currently PCC can be synthesized via three methods, namely the method of Solvay, caustic soda, and carbonation. In this study, the method used is the manufacture of PCC carbonation method, i.e. by passing carbon dioxide gas into a suspension. PCC quality tested by several parameters, purity of CaO 37.75 %, Fe3 + impurity levels of 6.72 ppm and a water content of 2.29 %.

Abstract

Water is a natural resource needed to fulfill the livelihood of many people, so it needs to be protected so that it can be beneficial to the lives and lives of humans and other living things. Batam City is one of the cities in Riau Islands Province which has a type of soil that cannot store water properly so that it uses an artificial reservoir as a reservoir of rainwater. Due to waste from industrial, domestic and other activities that have a negative impact on water resources. Then testing the iron and zinc content of the reservoir water in the city of Batam was carried out. Metal Iron and Zinc are metals that are needed by organisms in relatively small amounts. Based on Government Regulation No. 82 of 2001 class 1, allowed Iron and Zinc levels of 0.3 mg/L and 0.05 mg/L. The method used in this test is Inductively Coupled Plasma - Atomic Emission Spectrocopy (ICP - AES), with the principle based on atomizing elements so that they emit light at certain wavelengths which can then be measured. From the test, it was found that the iron content in Duriangkang reservoir 0.2339 ppm, Sei Harapan reservoir 0.0299 ppm, Mukakuning reservoir 0.0292 ppm, Sei Nongsa reservoir 0.4168 ppm, Rempang reservoir 0.0001 ppm, Tembesi reservoir 0.0420 ppm, Sei Ladi reservoir 0.0588 ppm. Zinc content in Duriangkang reservoir is 0.0083 ppm, Sei Harapan reservoir is 0.0554 ppm, Mukakuning reservoir is 0.0083 ppm, Sei Nongsa reservoir is 0.0004 ppm, Rempang reservoir is 0.0083 ppm, Tembesi reservoir is 0.0083 ppm, Sei Ladi reservoir is 0.0211 ppm. This shows that the reservoir water has fulfilled the class 1 water quality requirements stipulated by Government Regulation No. 82 of 2001 except Sei Nongsa reservoir for the parameters of Iron (Fe) and Sei Harapan reservoir for Zinc (Zn) parameters.
