<![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[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.]]>

<![CDATA[[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.]]>

<![CDATA[[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%.]]>

<![CDATA[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.]]>

<![CDATA[[Title: Chitosan/PVA Composite Nanofiber Biocompatibility Test as a Wound Wrap]. This study aims to make chitosan-based nanofiber from NTB local crab shells. The manufacture of nonofiber is intended for application in the medical world as wound dressing. Wound dressing was developed from the basic ingredients of chitosan from NTB local crab shells. This research was conducted using the electrospining method, namely by making fibers from nano-sized chitosan. The resulting wound dressing was analyzed using FTIR. The results of this analysis show that chitosan has an area of absorption or transmittance in some chitosan groups so that it shows a positive alloy on chitosan and PVA as antibacterial in wound dressing.]]>

<![CDATA[This study is a research on water hyacinth-based briquettes which shows the calorific value of each form of briquettes. The purpose of this study was to analyze the quality of water hyacinth briquettes with variations in pressure and pellet geometry. The quality analyzed includes moisture content and calorific value. The method of making briquettes starts from charcoal, pounding, then mixing with tapioca starch adhesive. The composition of the mixture used is 90% water hyacinth charcoal with 10% tapioca starch adhesive. 4 geometric variations are used, namely, solid box, hollow box, solid tube and hollow tube with 3 pressure variations, namely, 10 PSI, 20 PSI and 30 PSI. Test results and analysis,briquettes at a pressure of 20 PSI produces a calorific value range of 91.15 - 150.14 cal / gram. The resulting calorific value is higher than the briquettes at a pressure of 10 PSI and 30 PSI with a heating value range of 93.84 - 148.79 cal / gram and 89.81 - 135.39 cal / gram. Hollow briquettes produce a calorific value range of 107.24 - 150.14 cal / gram higher than solid geometric briquettes which produce a heating value range of 89.81 - 148.79 cal / gram. So that the contribution of the results of this research is that the community makes briquettes with shape and pressure with good results shown in this study.]]>
