<![CDATA[Silver metal found in the metal plating industry wastewater, industrial process photography and X-ray film process. Wastes that still lack the metallic ions of silver if thrown in the water without further treatment would endanger the life of organisms, mainly bacteria, plants and living things, as silver metal is a metal that is toxic in dissolved form. One separation technique can be used with supported liquid membrane (SLM) technique. This study aimed to identify the type of solvent and carrier compound to percent transport of silver metal from the feed phase to phase receivers with SLM techniques. This type of research used in this study was an experimental research in the laboratory. Percent transport of metal ions Ag + with techniques SLM had done by varying the type of solvent was n-hexane, kerosene, toluene and chloroform to dissolve the compound carrier TBP and D2EHPA with each concentration 1 M. The concentration of the metal ions Ag+ in phase receiver after separation techniques SLM was measured by Atomic Absorption Spectrophotometer (AAS) at a wavelength of 328.1 nm, then the calculated percent metal Ag+ ion transport. Based on the results showed that the percent of the silver metal transport centipede on the use of solvent n-hexane and chloroform, with transport by 33.9% percent. While the percent of the highest transport to the use of compounds that was using the carrier of carrier compound TBP, with transport by 33.9% percent.]]>

<![CDATA[The purpose of this KKN-PPM program is to accomplish a problem from cattles waste that has not been managed properly. Further management is directed towards making small-scale biodegesters into energy-independent villages. This devotion is implemented in Kidang Village of East Praya in Central Lombok Regency. The availability of an abundant source of cattle dung is spread in each private cowshed (there is no collective cowshed) because of the distribution pattern of Kidang Village residents in small groups, supporting the implementation of this program. The soil texture of cracked clay in the dry season, as well as the limitations of the water source cause the degister model are suitable for the condition. Degister applied is a small-scale biodegister, designated for 1 family with the number of cattle at least 2 cattles (cow). Biodigester is installed in 6 different location as a pilot program to Kidang Village community. Digester uses a 1200 liter plastic tank, with in let, out let, and out putt gas using a piping system. The digester is filled with ¾ part of the cattle dung, and ¼ of the part as the gas reservoir. The gas produced from the digester model shows a mixture of water : cattle dung with a 2: 1 ratio is faster than the 1: 1 mixture. In the mixture with a ratio of 2: 1, the gas has begun formed on day 11 with increasing pressures day by day, with the pressures of 73.26 Pa, 106.36 Pa, and 112.00 Pa.]]>

<![CDATA[In this study a decorative chrome electroplating process has been carried out with a copper base metal, metal electroplating is often used as a means to provide a thin layer on the surface of other metals or substrates using metal which has advantages in terms of property and corrosion resistance. In decorative chrome electroplating nickel and chrome are used as coatings, nickel and chrome are used as coatings because of their protective and decorative properties, protective means they can prevent corrosion and decorative because they look shiny so they look attractive. Copper metal is chosen because of its huge application in the community. This study aims to measure the corrosion rate in copper metal after a decorative chrome electroplating process based on electric current used during the electroplating process. This research is important because during the electroplating process a decorative chrome electoplating technique will be obtained in the form of modules, and the module will be used to train students to increase their skills. This research was conducted in the IKIP Mataram chemical laboratory with a time of one year. The process carried out in this study sequentially is to prepare an electrolyte solution used for electroplating, preparing the copper base metal to be free of oxide or rust, nickel coating and finally coating with chrome. From the coating process carried out then the results will be analyzed the corrosion rate by immersion in NaCl solution at a concentration of 36.05 grams / L for 336 hours, based on variations in electric current used during the electroplating process of 0.5; 1; 1.5; 2; and 2.5 Ampere, the corrosion rate results were 0.029; 0.013; 0.017; 0.022; and 0.012 mm / yr; while the copper metal which is not coated with a corrosion rate is 0.308 mm / yr. Thus it can be concluded that copper metal coated with nickel chrome will effectively resist the lowest rate of corrosion in the current given 2.5 Ampere.]]>

<![CDATA[Characteristics of electrochemical material that contains abstract concepts. Hence often have difficulty in teaching it. An effective approach as a solution is the SAVI-based interactive learning approach of interactive simulation. Learning SAVI-based interactive media has an animation program that is able to represent abstract concepts in electrochemical materials through visualization and not illustration of the concept in narrative. The purpose of this research is to know the influence of SAVI learning approach to students' critical thinking skill in electrochemical material. The type of research used is quasi-experimental research. The research design used is posttest only control group design. The sample was divided into two groups: experiment and control group. The research instrument uses critical thinking skill test through rubric. The results show that the SAVI approach has a positive effect on critical thinking skills compared to conventional methods. We conclude that the SAVI learning approach has been able to improve students' critical thinking skills.]]>

<![CDATA[Gondang Village is one of the villages that was badly damaged by the earthquake a year ago. In addition to swallowing fatalities, the earthquake also resulted in badly damaged houses and public facilities. Employers lose their business, so too workers lose their jobs. To start a new business, the victims did not have the capital and did not know what kind of business they would pursue. This service aims to provide skills to the community through chemistry entrepreneurship so that people can start entrepreneurship. Chemistry entrepreneurship involves the process of converting innovations from chemicals into products that can be marketed for commercial gain. The products to be made this time are a liquid detergent, dish soap, softener, and sof trika. These four products are basic needs in the household so this business opportunity is very promising. The KKN PPM program was held for 1 month. There were 93 people involved in this activity representing 11 hamlets. The stages of the KKN PPM activities are preparation, trial, production, and marketing review. All of these activities involved 20 students who worked with the community. The people of Gondang Village have received training in making liquid detergent, dish soap, softener, and hydrophobic along with a sales strategy. Product sales have increased in number based on the first and second evaluations. Community income also increased. The resulting product has been officially launched as a superior product in Gondang Village. The service team and students have successfully carried out community empowerment through chemistry entrepreneurship.]]>
