Authors: Pingak R K , Deta U A 
Published: June 2020

Abstract
Triplet-1s2s 3S1 energy levels of some light Helium-like ions (Li+ to Ne8+) were numerically calculated using a truncated-matrix method implemented in a simple Mathematica code. The two-electron wave functions were expanded in finite number of basis states consisting of hydrogenic s-orbitals. Here, the Hamiltonian matrix used was of size 15×15, 25×25 and 35×35. From the results, triplet-1s2s 3S1 energies of the ions were in good agreement with other advanced and highly accurate calculations in the literature. Comparisons with one of the most accurate calculations in the literature showed that our results were very accurate with the largest error in energy being only 0.135 % for Li+ ion and the smallest one being approximately 0.018 % for Ne8+ ion energy, when 35 basis states were used in our calculations. Errors from our calculations were also much lower than those from the geometrical model.

Abstract
Li4Ti5O12 (LTO) anode is one of ion lithium battery important components. LTO anode has been synthesized using solid state reaction method that was calcined at 900°C and produced relatively large particle sizes and low electrochemical performance. The Low electrochemical performance can be improved by replacing the anode synthesis method using sol-gel method. This research used the sol-gel method to synthesize LTO anodes with calcination temperature at 900°C and holding time at 2hr with the aim of obtaining homogenous particle size distribution with small particle size average and high discharging capacity. X-ray diffraction (XRD) characterization was carried out to find the crystalline phase formed while field emission-scanning electron microscopy (FE-SEM) was carried out to find the morphology and particle sizes distribution. Electrochemical performance of LTO anodes was measured from cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and charge-discharge (CD). The LTO-spinel phase was identified as the primary phase and TiO2-rutile phase as the impurity phase. The particle size distribution is 0.24μm and the sample consisted of particles that agglomerate without no pores. This anode has high electrochemical performance especially discharging capacity of 302 mAh/gr at 1C.

Abstract
A mobile robot had been made based on kinematics drive differential concept. This robot used odometry method in order to reach a position and determine its current position. Proportional Integral Derivative (PID) control has been applied for improving response of robot while it reach a detremined position. Two rotary encoder sensors were attached at right and left side of robot motors for measuring distance. While motor rotating, rotary encoder sensors counted a number of pulses conversed into left and right wheel mileage. Both of them were used to get robot position at certain time (x, y, and heading angle). Robot passed some tracks and reached two positions in each track as destination positions. These positions are the position which had final heading 30° and 90°on first track, 45° and 90° on second track, 60° and 90° on third track. PID control was examined by put mobile robot in first position 0,0,0°. Some PID parameters have been applied to examine the performance and response of robot. The increment of derivative parameter reduced the steady state error and increased the stability of system.

Abstract
Barriers to scientific creativity often make it difficult for physics teachers to recognize their creative potential, let alone train their students to be creative. The research aims to identify the physics teachers’ ability in practicing creative product design and their creative barriers. This research includes mix-methods using a survey approach and continued by Focus Group Discussion. It has involved 67 physics teachers in South Kalimantan divided into three groups (senior teachers, beginner teachers, pre-service teachers). The teacher’s answers are analyzed by descriptive qualitative. The results showed that teachers’ ability to design creative products limited to creative ideas and scientists; but it has non-integrated mathematical reasoning and technical design in designing an applicable product. The teacher’s negative belief in scientific creativity and their learning are the main factors of creating barriers. Other factors are limited study time, laboratory equipment, teaching materials, and the amount of material structure.

Published: June 2020

Abstract
Plastics generally cause global-scale problems because they cannot be degraded into the environment and causing a build-up of plastic waste. Biodegradable plastic material can be an alternative to solve the problem because of its nature which is easily naturally degraded by microorganisms. One of the natural wastes that can be utilized to become fillers in plastic mulch so it is more easily degraded is cornhusk because its utilization is still limited and cornhusk has high cellulose content. In this study, the extraction of cellulose was carried out on cornhusk to obtain cellulose by the alkali method. There was a decreased in hemicellulose and lignin levels, which indicated that the extraction process was quite successful. Then in the process of making biodegradable mulch films, Tinuvin P was added as an anti-UV agent and oleic acid was carried out as plasticizer and with several variations. The results show that the addition of anti-UV agent P and addition of oleic acid reduces the mechanical properties of biodegradable mulch and can control the rate of degradation of the biodegradable mulch film.

Authors: Mufida R Y , Kusumawati D H 
Published: June 2020

AbstractThe development of composites as biosensors is very broad, one of them is biosensors to absorb glucose. Composite materials characteristic as biosensors must fulfill the criteria including nanomaterials that have magnetic properties, electrical conductivity, and good catalytic properties. One of the composites that fulfill those criteria is rGO/Fe3O4. By varying the addition of Fe3O4in the making of rGO/Fe3O4composites, the composition of composites that have the most effective performance in absorbing glucose will be known. The variation of Fe3O4addition in this study is 0.1 gram - 0.5 gram, with 0.5 gram of RGO. The characteristics of rGO, Fe3O4and the rGO/Fe3O4composite are known by the XRD and FTIR analysed based on relevant previous studies. Glucose biosensor absorbance was tested by UV-Vis, a composite with mass variations of Fe3O40.1 gram, 0.2 gram, 0.3 gram, 0.4 gram, and 0.5 gram. Peak absorption of the composite of 0.1 gram Fe3O4shows high glucose concentration, it can be seen that the composite does not absorb glucose properly. The 0.2 gram composite has the lowest absorption peak so that this composite is the best biosensor. Because with the addition of Fe3O4mass shows the peak absorption is also higher. So, composites have a maximum limit in absorbing glucose.
