This article describes the idea of a mobile learning model - NOS for enhancingstudents' scientific literacy and student responses to these ideas. This article iscompiled based on literature studies, simple observations on several variablessupporting mobile learning at IKIP Mataram, and evaluating prospective userresponses to the development idea using a questionnaire. Respondents were 54students of IKIP Mataram Chemistry education. The response data is processedby percentage formula based on category criteria. Mobile-NOS learning islearning that applies the Nature of Science (NOS) learning steps with the supportof learning media in the form of mobile applications that can be applied in smartmobilephone. The six main steps in implementing learning are oriented to Natureof Science (NOS), namely: (1) Reading the context on electronic articles; (2) Indepthquestioning; (3) Observation of cases and targets; (4) DemonstrationProcedure; (5) Library Search; (6) Implementing Procedures; (7)Communicating Science Knowledge; and (8) Authentic Assessment.The results ofthis study showed an average response to the idea of developing NOS-orientedmobile learning at 85.23% with a very good category.

In this study a study of the effect of TiO2 photocatalysts and Hg (II) ions in thewastewater of the silver industry in Ungga Village, Kec. PrayaKab. CentralLombok to the effectiveness of Cu (II) photoreduction which is catalyzed byTiO2. The photoreduction process is carried out by irradiating liquid wastecontaining Cu (II) and Hg (II) ions without or by adding TiO2 photocatalystpowder in a closed reactor equipped with UV light. The condition of thephotoreduction process is 50 mL of silver waste containing Cu (II) and Hg (II)with a reaction time of 24 hours and a mass of TiO2 20 mg at 10 ppm Cu (II) ionconcentration. Photoreduction results are determined based on the difference inthe concentration of Cu (II) ions with the concentration of residual Cu (II) ionsin silver waste without the addition of TiO2 photocatalysts. Furthermore, thedata obtained compared to the results of Cu (II) photoreduction catalyzed bypure TiO2 laboratory scale. The amount of metal in the mixture was determinedby the Atomic Absorption Spectrophotometry (AAS) method. The results showedthat in silver handicrafts containing Cu (II) and Hg (II) ions the addition of TiO2can increase the effectiveness of Cu (II) photoreduction from 6.57% to 33.38%,which begins with the adsorption process. Hg (II) in silver handicraft wastecauses inter-metal reduction competition so that it can reduce the effectiveness ofCu (II) ion photoreduction catalyzed by TiO2 by 9.84% when compared to thepercentage of Cu (II) ion Ti2O scale scale laboratory testing.

Dye Sensitized solar cells (DSSC) can use two types of coloring, namely dyesderived from organic and inorganic materials. The choice of natural dyes ispreferred by looking at the enormous potential of biodiversity in Indonesia,where there are still many untapped especially for plants that have a tendency tobe colored or contain chromophore dyes such as chlorophyll (play a role in theabsorption of light for photosynthesis). The wavelength when characterizing thedye as a solar cell must be in the visible area (400 to 800nm). In this study thenatural dyes used are bebele leaves and kangkung which grow on the island ofLombok. The wavelength obtained for fresh bebele is 553nm, 605 nm and 665nm.The wavelength obtained for fresh kangkung leaf is 664.5 nm with the highestabsorption peak. From the results of the absorption stated that natural dyes havechlorophyll a and b groups which are absorbed in the UV-Vis region 600nm to700nm which means that they absorb the red most strongly. In the measurementof current strength and efficiency with multimeters on organic dyes in a row thatis fresh bebele leaves5 μA /cm2; 0.156; fresh kangkung leaves 4.2 μA/cm2; 0,131;dried bebele leaves 4 μA/cm2; 0.13; dried kangkung leaf 3 μA /cm2; 0.088.

Copper metal levels in silver craft waste can cause health problems in humansand pollute the surrounding environment. One method of processing wastewateris the adsorption technique using activated carbon dioxide. The first step is tofirst determine the copper metal content in silver handicraft waste in UnggaVillage, Central Lombok. Furthermore, the waste water is contacted withactivated carbon. The production of activated bagasse carbon consists of threestages, namely first dehydration by burning bagasse until it turns into carbon,second carbonation which is heating temperature of 500ºC, carbon yields of 100-200 mesh and third, activation by immersing 50 grams of carbon in 500 mL 15%NaOH during 12 hours. After that the carbon is dried at 110ºC and finally heatedat 500ºC for 1 hour. The bagasse carbon that has been made is put into 25 mL ofwaste water sample with a mass of 2 grams of adsorbent. The sample is thenstirred at various contact times of 30, 60, 90, 120 and 150 minutes at a speed of180 rpm using a batch system. The optimum contact time and concentration areused to calculate the efficiency of decreasing copper metal content by calculatingthe difference in copper metal content before adsorption and after adsorptionusing activated carbon dioxide. The concentration of all Cu (II) metals wasanalyzed using Atomic Absorption Spectrophotometer (AAS). From the researchit was found that the copper metal content in the sample was 14.5710 ppm. Theoptimum contact time for copper metal adsorption is at 120 minutes contact timewhich results in optimum adsorption efficiency in ferrous metals, namely84.88%.

This development aims to determine the characteristics and feasibility of multipleinquiry-based representation modules in the reaction rate material through theADDIE stage (Analyze, Design, Development Implementation and Evaluation)developed by Thiagarajan. This research and development was carried out untilthe development stage with adjustments based on development needs. Theassessment instrument used to determine the feasibility of the module is aquestionnaire sheet. The module feasibility was assessed by 2 material experts, 1media expert, 1 linguist, 1 colleague, 1 practitioner, and 10 students as subjects.Students involved in this study came from chemistry education study programsthat had undergone basic chemistry courses through limited trials. The data onthe value of the grievances obtained are still in the form of qualitative data andthen processed into quantitative data. Quantitative data are analyzed for eachaspect of the assessment. The final score obtained is converted to the level ofproduct feasibility qualitatively with the guidelines according to the criteria ofthe assessment category. The results of expert validation showed the averagepercentage (a) of material experts was 84% with very feasible categories; (b)media experts 90% with very decent categories; (c) linguists 97% with verydecent categories; (d) colleagues 79.6 categories worth%; (e) practitioners86.4% are very decent categories.
