The existence of the covid-19 pandemic that has hit Indonesia since February 2020 seems to be able to change the face of Indonesian education significantly. One of the things that has arisen as a result of the pandemic is the application of the Blended Learning model. The changing learning process makes the implementation of learning not maximal in class so that it causes a decrease in student learning outcomes. This study aims to determine the effect of blended learning on integrated social sciences learning outcomes in class VII and VIII students of SMPN 1 Palas, South Lampung. This study uses descriptive verification research methods with ex post facto and survey approaches. The population in this study were students of class VII and VIII of SMPN 1 Palas with a total of 294 students. The sampling technique in this study was probability sampling using simple random sampling. The sample calculation uses the Slovin formula, so that there are 169 respondents. Data collection techniques using observation techniques, interviews, documentation, and questionnaires. Hypothesis testing was carried out using a simple linear regression test. Based on the results of the research that has been done, it is concluded that there is a positive and significant effect of blended learning on learning outcomes of Integrated Social Sciences of 8.64 percent.

The goal to be achieved from this development research is to produce products in the form of waste utilization model books for elementary school students so as to provide guidance for physical education teachers in providing fun, creative and meaningful learning. This study used research and develompent (RnD) method from barg and gall consisting of ten steps, the subjects used in this study were students of SDN Tanjungsari and SDN Blanakan with a total of 68 subjects. The design of the experiment research is one group pretest posttest design.  The stages of this study are: introduction research, expert test, large group test small group test and effectiveness test. The effectiveness test in this study used the Harvard Step Test. The results of the model effectiveness test are known that the waste utilization model for physical fitness there is an increase, the pretest obtained an average figure of 33.57 and posttest obtained an average figure of 36.63. From the data can be concluded there is an increase after treatment. The results of the effectiveness test showed the results of t-count = 7818, df = 62 and p-value = 0.00 < 0.05, meaning that the physical fitness exercise model for elementary school students before and after treatment there was a significant difference. It can be concluded that the waste utilization model for physical fitness of elementary school students, effective and able to improve physical fitness

Research related to the magnetization of fossil fuels is currently believed to be able to improve the quality of combustion due to the cluster decluster effect on the fuel. Fossil fuels are finite and non-renewable. Meanwhile, non-fossil energy, especially bioethanol, despite having more environmentally friendly exhaust gas emissions and higher octane rating than gasoline, has a lower calorific value than gasoline. To overcome this deficiency, the fuel magnetization of a mixture of gasoline and bioethanol is carried out. The fuel is used in 4 stroke injection motorcycles. Furthermore, the performance of the 4-stroke injection motorcycle was observed. the fuel mixture without magnetization was used as a control variable. The intensity of the electromagnetic field used is less than 2,000 Gauss, this is different from previous analysts. As a result, the magnetized motorcycle experienced an increase in torque of 4.48 – 7.30%, power of 4 – 9.90%, and a decrease in SFC of 6 – 9.20%.

Penelitian ini bertujuan untuk mengetahui penerapan prinsip non diskriminasi dan kesetaraan dalam pengupahan bagi guru ngaji di Lembaga Tahsin Al-Qur’an Kota Pasuruan dan faktor- faktor yang mempengaruhi dalam pembedaan pengupahan bagi guru ngaji di Lembaga Tahsin Qur’an Kota Pasuruan. Guru ngaji masih dianggap sebagai golongan bawah yang memerlukan perlindungan untuk dijamin hak-haknya salah satunya yaitu upah. Perlindungan tersebut untuk menjamin kesetaraan serta perlakuan tanpa diskriminasi untuk mewujudkan kesejahteraan guru ngaji. Metode penelitian ini menggunakan metode pendekatan yuridis empiris, spesifikasi penelitian ini diuraikan secara deskriptif analitis. Metode pengumpulan data yang digunakan dalam penelitian ini adalah data diperoleh dari data primer dan data sekunder dengan menggunakan beberapa teknik pengumpulan data yaitu studi literatur dan wawancara. Sedangkan metode analisis data penelitian ini menggunakan teknik deskriptif analitis. Hasil penelitian menunjukkan bahwa penerapan prinsip non diskriminasi dan kesetaraan dalam pengupahan bagi guru ngaji di Lembaga Tahsin Qur’an Kota Pasuruan telah diterapkan. Hal ini bisa dilihat dari kesetaraan dalam kaitannya dengan besaran angka yang diterima setiap bulan disetarakan dengan UMK di kota Pasuruan.

The prevalence of child obesity worldwide has increased rapidly over the past 3 decades. The danger that threatens children is not only overweight or obesity but also malnutrition is still a disease that attacks children under five in developing countries. This study aims to determine whether there is a relationship between physical activity and body mass index of children in the coastal fishing village of Kenjeran, Surabaya City. This research was conducted using cross sectional method. The research, which was conducted in the coastal fishing village of Kenjeran, Surabaya, used the research subjects were 105 children in the area. Purposive sampling technique is a technique used for sampling. In this study, the PAQ-C questionnaire was used as an instrument to measure physical activity while measuring body mass index consisting of height and weight used microtoise instruments and digital scales. The data analysis technique used Spearman rank correlation with a significance level of < 0.05. The results of the coefficient correlation analysis are - 0.41 and also get a significance result of 0.680. Significant result > 0.05. The conclusion from the results of this study is that there is no significant relationship between physical activity variables and body mass index of children in the coastal fishing village of Kenjeran, Surabaya City.
