Abstract

Telah dilakukan penelitian mengenai serbuk material barium heksaferit (BaO.6Fe2O3)} dengan prekursor BaCO3 3,55 gram dan Fe2O3 17,24 gram. Sampel dihaluskan menggunakan high energy milling (HEM) selama 20 jam, kemudian dibuat pelet dengan diameter 2 cm dan ketebalan 0,5 cm. Setelah itu diberi perlakuan pemanasan (annealing) pada suhu yang berbeda yaitu 400oC, 800oC dan 1200oC. Hasil pengukuran pola difraksi sinar-X setelah di-annealing menunjukkan terbentuknya struktur kristal, tetapi variasi suhu tersebut tidak memberikan pengaruh yang berbeda. Dari hasil karakterisasi dengan TGA/DSC, terjadi penurunan massa sekitar 2,05% pada temperatur 160oC - 640oC, akibat menguapnya kandungan air dan pelarut yang terjebak dalam precursor. Penurunan massa juga terjadi pada temperatur 640oC - 875oC sebesar 3,28%, akibat dekomposisi fasa dan transformasi fasa dan puncak eksotermik terjadi pada suhu sekitar 450oC.

Abstract

Pemilihan media pembelajaran yang berbasis teknologi masih jarang diterapkan terutama pada beberapa mata kuliah fisika yang dianggap tidak dapat tersampaikan dengan baik jika disampaikan dengan multimedia. Pada penelitian ini diterapkan media pembelajaran fisika digital book dengan kvisoft flipbook maker untuk mengetahui pemahaman konsep mahasiswa terhadap materi kuliah Kapita Selekta Fisika Sekolah II dan mengetahui efektivitas penggunaan media pembelajaran fisika digital book. Peneliti menggunakan analisis multivariat yaitu MANCOVA dua arah dengan satu kovariat yang memanfaatkan program SPSS 16. Hasil penelitian menunjukkan terdapat pengaruh penggunaan digital book terhadap pemahaman konsep dan hasil belajar mahasiswa dari rata-rata 70 untuk kelas kontrol (gain ternormalisasi 0,4) menjadi 84 untuk kelas eksperimen (gain ternormalisasi 0,7).

Abstract

Noise pollution can come from noise generated by nature, one of which is noise from river flows. Therefore, the aim of this research was to determine whether the sound intensity level of the river flow is still below the threshold value or whether it has disturbed human hearing. The research method used was to measure the sound intensity level of the Cinangneng-Bogor river flow by using a sound level meter application. Measurement of the sound intensity level was carried out at 5 measurement points, namely in the middle of the river flow, on the river bank, at a distance of 5 m, 10 m and 15 m from the river bank to the land. Each measurement was carried out for 120 seconds. The results showed that the sound intensity level of the Cinangneng-Bogor river flow at several measurement points had different values, namely from the middle of the river to away from the river the values were 96.34 DbA, 92.31 DbA, 78.93 DbA, 76.58 DbA and 76.32 DbA. In conclusion, the further away from the noise source, the lower the noise level. The sound intensity in the middle and on the river bank was above the threshold value.

Abstract

This research develops scientific-based learning on black body radiation material, knows the feasibility of scientific-based learning modules, and sees student responses to scientific-based learning modules. Provide alternative teaching materials that can be used in physics learning. Learning can be easily done because the learning steps that are already in the module can be a solution for teachers and students learning physics does not look difficult and boring. The limited trial results obtained an average score of 3.2 or 80% in the "good" category and based on the results of the trial, it was obtained an average of 3.21 or 80% in the "good" category. These results can be ignored that the physics learning module with a scientific approach to black body radiation material is suitable for use in learning at school

Abstract

Breast cancer is the most common cancer in women, which is about 25% of all cancer incidents and is the second leading cause of death after lung cancer. Breast cancer can also occur in men, with a ratio of 1: 100 when compared to women. Cancer is a disease that causes high mortality in the world. Based on WHO data, in 2015 there were 8.8 million deaths caused by cancer.  Various methods have been developed to treat cancer, one of which is by using radiation therapy or radiotherapy. According to the International Agency for Research on Cancer (IARC), of the 10.9 million people diagnosed with cancer worldwide each year, about 50% need radiotherapy. The use of radiation for cancer therapy has not been widely used and is still limited in Indonesia. The purpose of writing this article is to describe the use of radiotherapy in the treatment of breast cancer through literature searches. The results of the literature search show that radiation technology has existed in Indonesia since 1927. Radiotherapy has become one of the important therapies in cancer treatment in Indonesia. The increasing number and development of radiotherapy facilities are expected to reduce the prevalence of cancer in Indonesia.

Abstract

Noise is one of the main environmental health problems in big cities. Noise is unwanted sound that can interfere with and or endanger health. Highway traffic is a major source of disturbing noise for most urban society. The impact of noise in the residential environment on public health includes: physiological disorders, psychological disorders, complaints and communication complaints. That The purpose of this study was to determine the noise level on Jalan Raya Tanah Baru and Jalan Raya Bogor and to find out whether the noise level on Jalan Raya Tanah Baru and Jalan Raya Bogor is still feasible for humans hearing. Based on the research that has been done, it is found that the noise level on Jalan Raya Tanah Baru is 71.5 dB. With the highest average noise level of 76 dB which occurred in the morning 08.30-09.00 WIB while the noise level on Jalan Raya Bogor was 76.16 Db with the highest average noise level of 80 db which occurred in the morning at 08.30-09.00 WIB and in the afternoon at 18.00-18.30 WIB. From the data, it can be seen that the noise level on Jalan Raya Bogor is higher than that on Jalan Raya Tanah Baru. This is caused by the number of vehicles passing on Jalan Raya Bogor more than Jalan Raya Tanah Baru. The noise level on Jalan Raya Tanah Baru and Jalan Raya Bogor is already at the level of "strong" and this is not good for health especially in human hearing.

Abstract

The existence of mobile learning-based learning media on the Android platform can make knowledge spread faster and not be limited by space and time. The existence of mobile learning is very much needed in the digital era as it is today, therefore this study aims to develop an android-based physics learning media with the MIT APP Inventor on the subject of static fluids. The research method used in this research is the research and development method with the ADDIE development model (Analysis, Design, Development, Implementation, Evaluation) which in this study was carried out to the Implementation stage. The learning media innovation that was developed was named EduPhysics, the output produced in the form of an Android-based learning application that can be accessed offline. This mobile learning has also been said to be feasible by experts based on the assessment of the validation results of media experts, material experts, and linguists, with average scores of 87%, 94%, and 87.5%, respectively. Based on these results, it can be concluded that the development of Android-based Physics learning media with the MIT APP Inventor on the subject of static fluids has an assessment with an "excellent" interpretation and falls into the "very feasible" category to be used as a learning medium.
