The topic of the lesson used was energy. This type of research used descriptive quantitative approach.Data collection techniques use tests which included aspects of context, content, and process. While the data analysis technique used descriptive statistics. The results of the investigation found that the scientific literacy ability of class X students in Senior High School 1 Kendari on the indicator aspect of content where the first indicator was the change in energy obtains a percentage of 70.83% with a sufficient category. Then for alternative fuel indicators got a percentage value of 79.72% with a good category. As for the energy supply molecular indicator, it s a percentage of 33.75% with a very low category. The ability of scientific literacy in class X students in Senior High School 1 Kendari in the process aspect indicator where the first indicator identifies scientific issues obtains a percentage value of 50.13% with low. Then, to explain scientific phenomena acquire indicator value percentage of 34.62% with a very low category. As for the indicator using scientific evidence obtained percentage value of 52.69% with a lower category. While the scientific literacy ability of class X students in Senior High School 1 Kendari on the indicator of context aspects where the first indicator of energy application in the technology field obtained a percentage value of 89.72% with a very good category. Then for the energy indicator in improving environmental quality, the percentage value is 29.16% with a very low category. To obtain the energy impact indicator value percentage of 17.08% with a very low category. Keywords—Science literacy, Physics learning

This research is caused by online learning, so that appropriate teaching materials are needed to support learning. This study aims to develop e-physics with the CinQASE model assisted by a professional flip pdf application that meets the valid, practical and effective criteria. This study uses the R&D (Research and Development) research method with a 4D development model (Define, Design, Develop, and Disseminate). The research object was the students of Senior High School Tahfidzul Qur'an Mu'adz Bin Jabal, which amounted to 54 students. Data collection techniques used validation sheets, questionnaires, and written tests. The feasibility e-module is assessed based on the validity of the e-module as seen from the assessment of 3 validators, the practicality e-module is seen from the evaluation of student responses, and the effectiveness e-module is seen from the increase in learning outcomes. The results showed that the CinQASE e-module with the professional flip pdf application developed was declared feasible with a validity result of 3.67 with a very good category. The results of the practicality of the e-module from student responses are 3.20 for class X-Putra and 3.21 for Class X-Putri with a very good category. The effectiveness results with n gain values of 0.34 (X-Putra) and 0.35 (X-Putri) are included in the good category. The developed e-module is declared feasible and has met the valid, practical, and effective criteria

This study proposes to determine the ability of activated charcoal from sugar palm bunches (Arengga Pinnata MERR) as lead adsorbent (Pb), copper (Cu) and chromium (Cr). The sample was carbonated with a temperature of 200-400°C, then mashed by using mortal and sieved using a size of 100 mesh. Samples were activated with activation temperature variations of 600°C, 700°C, and 800°C and characterized using Scanning Electron Microscope (SEM) with 2500x magnification and Atomic Absorption Spectroscopy (AAS). The SEM results indicate surface morphology of the best-activated charcoal of at a temperature of 700°C with uniformly distributed pore size. In the AAS analysis results obtained for Pb absorption capacity of 0.0082 mg/g and absorption efficiency of 86.86%, the Cu absorption capacity of 0.0203 mg/g and absorption efficiency of 94.37% and Cr adsorption capacity of 0.0243 mg/g and efficiency absorption 96.39%. The value of absorption capacity obtained the result of AAS characterization, and the best adsorption efficiency was at 700°C.

This research aims to determine the effect of activation temperature the crystal structure of activated charcoal. The material used activated charcoal bunches (Arengga Pinnate Merr). The process of making activated charcoal divided into two, namely the carbonization stage at a temperature of 250- 400 oC and the activation stage at a temperature variation of 600 - 800 ̊C. To find the crystal structure, the sample characterized by X-Ray Diffraction. The results of analysis the dominant elements diamond before activation with a percentage of 90.2% and an orthorhombic crystalline structure, where the lattice parameter a = 4.12700 Å; b = 4.93700 Å; c = 4.81900 Å. Peak Carbon has a hexagonal crystal structure in all temperature variations. Peak Graphite an orthorhombic crystal structure and at a temperature of 700 oC a hexagonal crystal structure formed. Therefore, giving temperature variations the activated charcoal of the bunches affects the structure of the formed Crystal. Wherein increasing the activation temperature, the crystal structure that forms look more amorphous marked by a widening diffraction peak intensity decreased crystals

Sensitivity improvement of gas sensor based on conducting polymer of Poly (3,4-ethylenedioxythiophene): poly (styrenesulfonate) (PEDOT:PSS) thin layer to motor vehicle emission gas has been studied. The PEDOT:PSS thin films were deposited on FR4 substrates by using a spin-coating technique. Then, the imprinting process of gas sensor was performed by injecting motor vehicle emission gas into the spin-coating chamber. Finally, the gas sensor was dried on a controllable hot plate. Sensor characterization was done by measuring the electrical properties and responses of the sensor to motor vehicle emission gas. Characterization of the sensor response was done by flowing gas in the gas chamber in which the sensor was placed. The results showed that imprinted PEDOT:PSS thin layer-based gas sensor has short response and recovery time, a good repeatability and higher sensitivity to motor vehicle emission gas. To this end, we found that imprinting method on the surface of PEDOT:PSS thin layer can improve the sensitivity of the sensor to motor vehicle emission gas.
