Abstract

The amide compound derived from humic acid has been applied as ionophore in ion selective electrode (ISE) measurement based on poly vinyl chloride (PVC) membrane.  The carboxylic acid group of the humic acid was first modified to the corresponding amide and is expected to form complex with the target cation. This work aims at obtaining selectivity coefficient towards Ni2+ ion.  The products of the reactions were observed using infra red (IR) spectrometer.  The amide compound derived from humic acid was immobilized into the membrane with composition percentage (w/w) as the following 32% of PVC, 64% of plasticizer of either [orto-nitrophenil octyl ether (NPOE) or dioctylpthalate (DOP) or dibenzyl ether (DBE)], 2% of lipophilic anion [sodiumtetraphenylborate (NaTPB), and oleic acid], and 2% of  ionophore the humic amide, respectively. The results show that ISE membrane give selective response to the Ni2+ ion at pH of 4,5 with response time of approximately 80 seconds. Among many others,  the cations that give strong emf interference include Cu2+,Li+,  K+, Pb2+, Na+, Zn2+, and Ca2+. The Nernstian factor of ISE membrane is close to +28 mV per decade with  linear range of concentration of pNi2+ of 1-6, with composition PVC membrane,  DBE as plasticizer, oleic acid as lipophilic anion, and humic amide as ionophore, respectively.

Abstract

In this research has been developed the application of flat coil as vibration sensor for early detection of earthquake. The flat coil is a very thin wire winding and acts as an inductor. This flat coil along with the capacitor constructs an oscillator which generates frequencies depending on the value of inductance and capacitance. This oscillator is called the LC oscillator. The flat coil inductance depends on the distance of the metal object in front of the flat coil. If the inductance changes, the frequency will change as well. Frequency can be converted into voltage form to represent distance. This effect is then applied to low frequencies using a pendulum on the sensor housing. The sensor system created can measure low-frequency vibrations in the range 0.26 - 1.0 Hz. Based on the research, the vibration sensor that has been made can measure one of the low frequency vibrations of 0.468 Hz at the frequency of 0.46 Hz vibration source

Abstract

One of the subjects in the physics education program is Biological Physics. The learning outcome of the course is able to analyze variously integrated and applied physics in understanding biology and be able to apply it. However, the duration of the lecture is not sufficient to train maximum analytical skills in each chapter and every meeting. Efforts to overcome this are by applying online classes to support face-to-face lectures in class with assistance from e-learning in the form of Schoology and Edmodo. The purpose of this study is to describe whether or not there are differences in analytical skills between students who carry out learning with the help of Schoology and with Edmodo's assistance. This type of research is quasi-experiment with Non-equivalent Group Posttest-Only Design methods. Samples were students of Physics Education, Lambung Mangkurat University who attended the Biology Physics course 2017/2018. Data was collected through posttest from classes that use Schoology and classes that use Edmodo, which consists of 4 questions to determine analytical skills with matching, specifying, analyzing error indicators, and generalizing indicators. Based on the results of the study, obtained sig (2-tailed) value of 1.66> 0.05. Therefore, the results of this study indicate that there is no difference in the ability of analysis between classes that carry out Schoology-assisted learning and Edmodo-assisted learning. Thus, both Schoology and Edmodo can be used as an aid in learning to train and improve students' analytical skills.
