Is conceptual learning based on conceptual change text (CTT) effectively applied to PGSD students\u27 science classes?
No full textFor Elementary School Teacher Education (PGSD) students, the introductory science concept course is part of the compulsory course. The understanding of PGSD students in basic science concepts will affect the quality of learning in the classroom. This research was conducted in odd semesters with 60 students who attended lectures on basic science concepts, and the sample selection was made randomly. To collect data on the effectiveness of the implementation of CCT, instruments used in the form of cognitive and clinical test questions have gone through validation and reliability tests. Students were divided into two groups in the study: the experimental group using CCT-based contextual learning as teaching materials and the control class using ordinary teaching materials. Based on the N-Gain data found in the field, there was a significant difference between the experimental and control groups; the control class had an N-Gain value of 0.54, while the experimental class was 0.81. The data revealed that learning using CCT successfully increased students\u27 understanding of concepts in the material cycle and created a better environment compared to the control class. However, based on interview data, both experimental and control class students were interested in learning the concept of the energy cycle and environmental pollution, and there was no significant difference

Perencanaan manajemen risiko atlet berprestasi Indonesia (Studi kasus atlet dengan risiko cedera tinggi)
No full textAtlet berprestasi memiliki risiko yang bisa menyebabkan kesulitan keuangan saat pensiun dari olahraga. Atlet dengan risiko cedera tinggi berpeluang lebih besar mengalami kesulitan keuangan karena berpotensi pensiun lebih dini akibat cedera. Tujuan dari penelitian ini adalah untuk mengetahui bagaimana manajamen risiko yang dilakukan atlet berprestasi dari cabang olahraga dengan risiko cedera tinggi untuk meminimalisir risiko saat pensiun dengan mengoptimalkan pendapatan yang dimiliki ketika masih aktif sebagai atlet. Landasan konsep yang digunakan dalam penelitian adalah manajemen risiko dengan dua perencanaan, yaitu perencanaan keuangan menggunakan perencanaan keuangan pribadi milik Kapoor, Dlabay dan Hughes (2009) dan perencanaan pendidikan. Wawancara mendalam dilakukan terhadap empat atlet berprestasi dan satu perwakilan federasi serta studi dokumen. Hasilnya, manajemen risiko yang dimiliki keempat informan yaitu tabungan dari gaji pegawai negeri sipil dan honor atlet, investasi berupa tanah dan properti, dan rumah atas nama sendiri. Manajemen risiko yang dimiliki masih membuat informan rentan terpapar risiko saat pensiun karena hanya mengelola risiko dari sisi materi yang bisa habis. Sementara itu keempat informan tidak melanjutkan pendidikan tinggi. Idealnya, manajemen risiko juga dilakukan oleh federasi dengan membuka peluang beasiswa untuk atlet melanjutkan pendidikan tinggi. Rekomendasi dari penelitian ini yaitu pemerintah perlu mendorong dan menyediakan beasiswa afirmasi untuk pendidikan tinggi atlet.
Indonesian athlete risk management planning (Case study athletes with high-risk injury)
Abstract
High-achieving athletes are at risk of causing financial difficulties when they retire from sports. Athletes with high injuries are more likely to experience financial difficulties due to early retirement due to injury. The purpose of this study was to see how risk management performed by high-achieving athletes from sports with high injuries to minimize risks at retirement by optimizing the income they had while still active as an athlete. The concept used in this research is risk management with two plans, financial planning using private financial planning by Kapoor, Dlabay and Hughes (2009) and educational planning. In-depth interviews were conducted with four athletes and one representative of the federation as well as document studies. The results of risk management owned by the four informants are savings from salaries of civil servants and athletes\u27 honor, investment in the form of land and property, and houses in their own names. Athlete is still vulnerable to be exposed by risk during retirement. The four informants did not continue their higher education. Risk management is also carried out by the federation with scholarship opportunities for athletes to continue their higher education. The recommendation of this research is that the government encourages and provides affirmative scholarships for higher education athletes

The sports activity of badminton and responses to changes in blood uric acid at productive age
Abstract
This study aims to determine whether there was a response to changes in uric acid levels due to the physical activity of badminton. The design of this study is a quasi-experimental. The sample used in this study was eight respondents with certain criteria. Treat physical activity twice on different days with 4 measurements of uric acid levels. The method of this study is repeated measure analysis. When subjects are measured repeatedly, requiring fewer subjects per experiment, then repeated measures analysis can be used. The results showed that the treatment of badminton had a significant effect on changes in uric acid levels with a probability value of 0,038. These results were obtained by using the Greenhouse-Geisser test where the assumptions of normality and homogeneity were satisfied. From the marginal test results using pairwise comparisons, there was a significant difference in the average uric acid levels at 15 minutes after exercise and 9 hours the following day, where there was a decrease of 1.169 mg/dl. Badminton can reduce uric acid levels, which is indicated by a decrease of 0.15 mg/dl at 09.00 the next day compared to before exercise. Marginally, this decrease is not statistically significant, but regular badminton can be an option for physical activity for those who want to reduce uric acid levels

A New Two Switched-Impedance Network for High Ratio Quasi-Z-Source Inverter
No full textThe increasing demand and widespread of renewable energy inherently compel the development of power electronics converter as an interface between consumers and the energy source/s. This paper presents a new two switched-impedance networks qZSI converter called High Ratio Two Switched-impedance quasi-Z-Source Inverter (HR2SZ-qZSI). Compared with the previous topology, this proposed HR2SZ-qZSI topology can achieve higher voltage gain with lower shoot-through duty ratio, and a higher boost factor. This paper also discusses comparative analysis between the previous topology and the proposed HR2SZ-qZSI topology. Furthermore, the simulation and experimental data are presented to prove the theoretical analysis of the proposed HR2SZ-qZSI topology. Despite the additional components needed, it accentuates that this proposed converter retains all features of qZSI: common ground point between the dc source and converter and smooth input current operation. Furthermore, almost all the devices rating including capacitor and diode voltage, and inductor current ripple are lower than the preceding relevant two switched-impedance qZSI family. Accordingly, this proposed HR2SZ-qZSI clearly a good power conditioning alternative for renewable generation system
