[Title: The Mechanical Test of Lightweight Brick Made from Gold Processing Waste with Variations in Coal and Cement Waste]. The purposes of this research are to make lightweight concrete using waste processing of gold with variation fly ash and cement the better than conventional concrete. The value of this research has tested mechanics which comprises density, porosity and strength. The research has done with some stage are: 1) Make lightweight concrete using LPE with variation fly ash and cement. 2) Characterization of the samples which comprise density, porosity and the strength, 3) Analysis of tested mechanical lightweight concrete. The value of lightweight concrete to make with variation composition fly ash and cement in a series are: (0/100), (5/95), (10/90), (15/85), (20/80) who are in volume. To make lightweight concrete with composition foam and water controlled as much as 10 ml and 150 ml at all of the sample. So we get the density value of lightweight concrete without fly ash is 1.61. In lightweight concrete with fly ash, we get the minimum density of lightweight is 1.15. The porosity value of lightweight concrete without fly ash is 13.6%, and the porosity value of lightweight concrete with fly ash is 8.0%. The compressive strength of lightweight concrete without fly ash is 1.629 MPa and the compressive strength of lightweight concrete with fly ash is 1.772 MPa. The value shown to process waste processing of gold with variation fly ash and cement to be lightweight concrete can get mechanical in character of lightweight to be better than conventional concrete.

[Title: Test Press Concrete of Gold Processing Waste With Variation of Rice Husk Ash Composition]. Lightweight concrete has been made from waste raw materials processing of gold and ash husk of rice with cement as the supporting materials, foam, and ADT. The purposed light brick-making determined the density and compressive strength. Concrete light created by variations in waste processing of gold and ash husk of rice was respectively 10% LPE + 90% ASP, 25% + 75%, 50% + 50%, 75% + 25%, 100% + 0% (in% volume), hardening time for 11 days. Parameter test performed include density test and compressive strength test. Test results showed that the density and the compressive strength of lightweight concrete with a variation of plus gold processing waste and ash husk of rice, the amount of cement on the conditions remained and the drying time for 11 consecutive days, the density of 1.005 gr/cm3, 0.986 gr/cm3, 1.077 gr/cm3, 1.091 gr/cm3, 1.133 gr/cm3 and the compressive strength of 1.34 MPa, 1.16 MPa, 1.77 MPa, 1.03 MPa, 1.29 , The intensity of the density and the compressive strength was influenced by the amount of foam mix, rice husk ash and ADT.

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 Â¾ part of the cattle dung, and Â¼ 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.

This paper introduces a new process of gold recovery using nanofiber PVA/Chitosan from a gold-cyanide solution. Gold recovery in cyanide solution is made using nanofiber PVA/Chitosan produced with electrospinning technique. This research was conducted through several stages, 1) The designing of electrospinning tool, 2) Synthesis of nanofiber PVA/Chitosan with electrospinning technique, and 3) Gold recovery experiment using nanofiber PVA/Chitosan biosorption with the variations of initial concentration and time. The results showed that nanofiber PVA/Chitosan could be used as a gold ion absorber. The occuration of the isotherm process follows the Freundlich isotherm model, which is advantageous and occurs on a heterogeneous surface. From the results, it was agreed that nanofiber PVA/Chitosan is potential for gold recovery.

[Title: Development of Lightweight Brick Based on Traditional Gold Processing Waste with Water Hyacinth Booster]. Research has been carried out on the manufacture of light brick made from gold processing waste with water hyacinth filler. The study was carried out by varying the direction of water hyacinth fiber as filler in light brick making. The direction of the filler is arranged in a horizontal, orthogonal and random direction. In each filler direction, the percentage variation of water hyacinth is arranged with the volume fraction 0%, 15%, 30%, 45%, 60%, from the total volume of the amount of light brick. The test results show that in the horizontal fiber direction the compressive strength is (2.43; 0.25; 0.54; 0.24; 0.50) MPa with a density (1.62; 1.34; 1.58; 1.42; 1.25) gr /cm3. In orthogonal direction the compressive strength was (2.43; 0.26; 0.80; 0.63; 0.77) MPa with density (1.62; 1.42; 1.49; 1.53; 1.42) gr/cm3. While in the random direction the compressive strength was (2.43; 0.73; 0.69; 0.59; 0.65) MPa with a density (1.62; 1.20; 1.41; 1.13; 1, 20) gr/cm3. From these data by comparing with previous studies, the most stable compressive strength and density values are formed in orthogonal directions. While the density value is most formed in random direction. In all directions the compressive strength and stable density were formed in the 60% volume of filler. The test results show that the light brick that is formed into the category is very light (entered in 0.6 - 1.6 gr/cm3 range) and floating in water, with medium compressive compressive strength.

[Title: Making Chitosan From Shrimp Cup As Gold (Au) Adsorben]. This study aims to make chitosan from shrimp shell as golden adsorbent. Stages of chitosan preparation include demineralization stage using 1,5M HCL, deproteination stage using 3.5% NaOH to obtain chitin powder, then followed by chitin deacetylation stage using 60% NaOH to produce an anime that is chitosan. Subsequently, the chitosan obtained was characterized, analyzed functional group with FTIR and determined its adsorption capacity against Au metal ion, Au content in the sample before and after adsorption was measured using AAS. The results showed chitosan characterization as follows: rendeman 45.83%, have powder texture, white colour, odourless, have moisture content 1.55%, perfectly soluble in glacial acetic acid 2% and purple positive with ninhydrin solution showed chitin has turned into chitosan. Based on calculations from the results of the resulting chitosan FTIR data has a degree of deacetylation 71.17%. From the result of analysis by using AAS that chitosan obtained able to adsorb Au metal from concentration 8.55 ppm decrease until 5,09 ppm with adsorption percentage equal to 40.46%.

This study aims to develop a 'learning module' identification of material content based on research and local wisdom. This module is a refinement of the Material Physics module. This course is an option; therefore the content tends towards the development of talent and interest to motivate the Master's degree. During this study more based on literature studies, the means are very limited. As a result, many curiosity and student awareness can not be missed because learning through research is very limited. The development of research-based modules and local wisdom can support the needs of students to conduct research. The research method used in this research is R & D research using Borg & Gall development model including product analysis, development, expert validation and revision, small field trial phase, large scale field trial and final product result. Learning module on subject matter identification of research-based materials and local wisdom as a product of development.
