Abstract

Rare Earth Elements (REE) is an interesting chemistry topic, especially due to current technology development. However, new learning designs of REE need to be developed for Pre-service Chemistry Teachers (PCT) as it is not yet available. A good design is constructed by analyzing PCT pre-conceptions based on the technical difficulties faced by the students during teaching process. The study aims to identify PCT's pre-conceptions focusing on REE topic. We conducted this research involving 17 chemistry education students at the Universitas Pendidikan Indonesia, Bandung. Data was collected through interviews and analyzed using the Qualitative Content Analysis (QCA) method. Our results highlight that PCT had difficulties with chemistry content of REE, especially about electronic configuration, magnetic, and luminescence properties. In addition, PCT faced difficulties correlating electronic configuration's chemistry content into contexts. Based on the interview results, 88.2% of the students agree with the development learning design for undergraduate chemistry students. As a result, we conclude that technical difficulties and misconceptions about REE can be overcome by developing the learning design based on the need of the students.

Abstract

Has made generating fluid flow wiper roll method used in measurement systems Fe concentration of porphyrin-based GMR sensor. This measurement system requires a low flow and can be controlled. Generating low flow can be generated with a wiper roll method. Wiper roll method works based on circular sweeping using three roll bearings. Three bearings are used to suppress the elastic hose interchangeably. Shifting the emphasis bearing against the elastic hose causes the fluid flow. Three roll bearing load divided by the same angle is 120o with a radius of 30mm to the length of the shaft so as to produce the same trajectory. The test results showed that the speed of the motor has a sensitivity to the motor voltage for 4,75rpm / V, the velocity of fluid flow sensitivity to the motor voltage for 0,015mL / V and the motor starts to respond after the motor voltage is greater than 3 volts. Key Word : Flow Fluid Generator, Roll Wiper Method, sensitive.

Abstract

This study aims to utilize benzotriazolium salt-ionic liquids (ILs) as solvents in the oil palm empty fruit bunch (EFB) waste pretreatment along with bibliometric analysis using VOSviewer. Three ILs have been synthesized and tested as EFB solvents by a microwave-heating method. Those are organic salts of 1,3-methyl-octyl-1,2,3-benzotriazolium ([MOBzt]+) cation with three kinds of anions such as bromide ([Br]-), acetate ([CH3COO]-), and thiocyanate ([SCN]-). The bibliometric analysis showed that new research needs to be conducted to improve the development of research relating to biomass pretreatment. The highest solubility of EFB is in [MOBzt]CH3COO is about 7,5% w/w. The effect of anions on the ability to dissolve EFB is CH3COO-SCN-Br-. When subject to ILs pretreatment, EFB exhibited increased cellulose crystallinity, changed in the structure of cellulose I to cellulose II, reduced particle size, and decreased lignin content compared to untreated one, improving the glucose yield from enzymatic hydrolysis. The highest glucose yield (1,237 mg/mL) was obtained when the EFB was pretreated by [MOBzt]CH3COO with enzymatic hydrolysis for 24 hours. This research is expected to contribute to the development of new biomass pretreatment methods.

Abstract

The effectiveness of learning can be increased by strengthening teacher’s competence and pedagogy. The targets of learning chemistry during the industrial revolution 4.0 include understanding the concept of chemistry and its relation to daily life. Based on the results of the 2017-2019 National Examination (UN) study conducted by the madrasa team, it is known that atomic structure and chemical periodicity is one of the materials considered difficult and in teachers and students, so that understanding on these topics needs to be improved. Increasing the understanding of chemical concepts needs to be solved intensively by demanding a variety of problem that is packaged through learning from daily phenomena. One type of learning that can be used is Problem Based Learning (PBL). The selection of PBL learning because it is start with complex daily life problems and also demands High Order Thinking (HOTS) of students and teachers. PBL-based learning can be socialized to teachers through Community Service (PKM) activities using the Community Education method in the form of workshops and assignments including: curriculum, conception, misconception analysis, and preparation of learning tools, so in the future teachers can develop a learning tool based on PBL independently with right conception.Efektivitas pembelajaran dapat ditingkatkan dengan cara menguatkan kompetensi profesional dan pedagogi seorang guru. Target pembelajaran kimia pada masa revolusi industri 4.0 diantaranya pemahaman konsep kimia dan keterkaitannya dengan kehidupan sehari-hari. Berdasarkan hasil telaah Ujian Nasional (UN) 2017-2019 yang dilakukan oleh tim madrasah, diketahui bahwa materi struktur atom dan sifat periodik unsur adalah salah satu materi yang dianggap sulit dan sering ditemukan miskonsepsi pada guru dan siswa, sehingga pemahaman pada topik tersebut perlu ditingkatkan. Peningkatan pemahaman konsep kimia semacam ini perlu dilakukan secara intensif dengan menuntut ragam penyelesaian masalah yang dikemas melalui pembelajaran dari fenomena keseharian dan penyelesaian masalah. Salah jenis pembelajaran yang dapat digunakan ini adalah pembelajaran Problem Based Learning (PBL). Pemilihan pembelajaran dapat PBL dilakukan karena pembelajaran ini diawali dari masalah kehidupan sehari-hari yang bersifat kompleks dan juga menuntut tuntutan kemampuan High Order Thinkings (HOTS) siswa dan guru. Pembelajaran berbasis PBL dapat disosialisasikan kepada guru melalui kegiatan Pengabdian Kepada Masyarakat (PKM) dengan menggunakan metode Pendikan Masyarakat berupa workshop dan penugasan meliputi: analisis kurikulum, analisis konsepsi, analisis miskonsepsi, dan penyususnan perangkat pembelajaran, sehingga diharapkan kedepannya guru dapat menyusun suatu perangkat pembelajaran berbasis PBL secara mandiri dengan konsepsi kimia yang baik

Abstract

Taxation is one of the most important sources of funding for Indonesia, where income from taxes will be allocated for infrastructure development and public services. Taxes can have a big impact on government income and state budget budgeting, the Indonesian government has made various tax policies and regulations to maximize tax department income. This is because companies as taxpayers indicate tax as a burden that they want to avoid because they can reduce the company's net profit. The difference in interests between the government and the taxpayer leads to tax avoidance or tax avoidance by the taxpayer in the form of exploiting tax law loopholes. This article aims to test the effect of Return on Asset and Current Ratio on the Cash Effective Tax Rate on PT Harum Energy Tbk. ROA is the company's profit-making capability. Meanwhile, CR is the company's ability to pay off its obligations smoothly. This article uses descriptive methods and quantitative approaches. The data in this article is secondary data taken from the financial statements of PT Harum Energy, Tbk and supported by library and documentation studies processed statistically and quantitatively. The results of this study concluded that partial Return on Assets and Current Ratio had a negative and insignificant effect on the Cash Effective Tax Rate. Simultaneously ROA and CR have no significant effect on CETR. The contribution of these two variables was only 37.4% meaning that 62.6% of CETR was influenced by other factors outside this study

Abstract

This research aims to create and evaluate the performance of environmentally friendly biobattery based on carrageenan and rotten tomatoes to reduce B3 waste. To make a biobattery based on carrageenan and rotten tomatoes, five ratios of carrageenan and rotten tomatoes mixtures were used with the composition of carrageenan values of 1, 2, 3, 4, and 5% for each type of battery. The parameters observed in this study were the potential difference, current strength, and stability of the biobattery. Carrageenan was added to prevent battery leakage and maintain battery stability. As a result, the biobattery has a potential difference value equivalent to a commercial battery, namely 1.5 V, but the current generated is still low. On the other hand, biobatteries can be applied to alarm clocks. The difference in carrageenan concentration has no significant effect on the value of potential difference, current strength, power, recharging ability, and application on wall clocks, as well as the stability of the biobattery. The experiment was carried out with the hypothesis that husk ash can absorb rotten tomatoes, preventing electrolyte leakage. However, the resulting biobattery is still leaking. After that, we modified it again by using electrolytes made from rotten tomatoes and coconut dregs, but the leakage was still the same. Therefore, the biobattery made from a combination of carrageenan and rotten tomatoes was assumed to keep the battery more stable and prevent leakage. This research was expected to contribute to the development of environmentally friendly batteries to reduce B3 waste, along with the increasing need for batteries in the era of industrial revolution 4.0.
