Abstract

The lithium ferrous phosphate carbon composite (LFP/C) cathode material has been successfully synthesized using solid-state reaction method by utilizing one of the natural sources of iron rocks in Tanah Laut, Kalimantan, as the base material of Fe. Solid-state reaction method was done by using high energy ball milling tool. The LFP cathode material was prepared using a base material (Li2CO3), Fe3O4, and (NH4)2HPO4 in a ratio of 3:6:2 and 5% wt. of Citric acid as a carbon source. There were some variations of calcination temperature used under inert conditions at 400 °C, 500 °C, 600 °C, and 700 °C to determine the effect on the phase structure and electrical conductivity produced by LFP/C cathode composites. Characterization of phase structure was done by using X-ray powder diffraction (XRD), while the conductivity value of the sample was tested using Electrochemical Impedance Spectroscopy (EIS). The analysis of the diffraction pattern shows the largest composition of olivine structure formed at 700 °C at 93.3% wt. with Fe2O3 impurities of 6.7% wt. The highest conductivity value of LFP/C is shown by sampling with 500 °C calcination temperature with a total conductivity value of 5,676 x 10-3 S.cm-1.

Abstract

The Covid-19 pandemic has a broad impact on all sectors, including the education sector. Almost all learning from elementary to tertiary level (university) which was originally face-to-face has turned into distance learning (PJJ) or online. This study aims to see the effectiveness of online learning, especially in exact subjects. For example, in learning Basic Physics which has practical aspects, there are several problems during the pandemic, such as, 1) the limitations of the face-to-face implementation of the Basic Physics practicum during the pandemic, 2) the limitations and inconsistencies of conventional modules used in practicum implementation in distance education, and 3) The use of a Content Management System (CMS) in e-lerning that has not been maximized is an obstacle that requires immediate handling. Therefore, the researcher tried to develop a practicum e-Module using the Research & Development research method with the Rowntree development model collaborated with the Tessmer evaluation model. The results obtained in the study showed an increase in student positive motivation in doing independent practicum with the help of e-modules. The resulting E-module development can be said to have met the practical criteria, shown from the recapitulation of the percentage results of the questionnaire sheet assessment at the one-to-one stage of 84.66% and and the small group stage of 78.22%. The feasibility of the e-module that has been made is also quite good, seen from the validation results by the validator on the aspects of material, media, design and accessibility, on average, it is> 80%.

Abstract

Indonesia is a democratic country for General Elections (Election) which are carried out directly, freely, confidentially, honestly, and fairly. Several stages of the election, among others, begin with compiling a permanent voter list (DPT), determination of polling stations (TPS), and recapitulating election results. Various factors, including the demographic factor, can affect citizen participation in the general election. Demographic data covers Energy, Geographic, Education, Health, Population, Economy, Communication, and Transportation factors. This study tries to combine election data with demographic data taken from the official website of the Central Statistics Agency (BPS) of Mojokerto Regency and data on the results of the 2019 Election calculations taken from the official website of the General Election Commission (KPU) of Mojokerto Regency. Preprocessing steps are data cleaning, data integration, and correlation attributes for a more optimal presentation of the dataset and the distribution of four split datasets (training data and testing data) to find the best results. Implementation of classification method with Logistic Regression (LR) algorithm to predict community participation at the TPS level. From the test results of four split datasets, the highest predictive value was 64.80% in composition 3 with a ratio of 80:20, where 127 data were labeled low, and 291 data were labeled high.

Abstract

Implementing a democratic general election is expected to produce people's representatives who can channel the people's aspirations. Demographic data is information that discusses a group of people with several related attributes and involves many factors. In this study, we will relate the relationship between the implementation of elections and the condition of demographic data with a benchmark for the form of public participation in the election. By utilizing 2019 election data and Bangkalan Regency demographic data from the Central Statistics Agency (BPS), it is expected to determine the relationship between the two conditions of the dataset on the form of public participation at the polling station (TPS) level. By starting with the Preprocessing step, it implement a classification method with the Decision Tree (DT) algorithm to predict community presence at the polling station level. There are three versions of the dataset that will be used in modeling, namely initial data that has not been selected for attributes (version 1), data that has been chosen using correlation-based attribute selection (version 2), and data that has been selected using chi-square attributes ( version 3). The results show version 1 with a prediction of 81%, followed by version 2 with a prediction of 81%, and the last is version 3 with a prediction of 70%. The detachment model's formation with the selection attribute has a different impact, and the relationship between the election dataset and demographics has a significant effect, as indicated by the prediction results of version 2.
