Abstract

This research aims to investigate the practicality of the CT-based learning integrated in the physics high school subject through a development of student worksheet. The CT-based learning adapted from Palts and Pedaste’s problem-solving cycle for CT and involved Weintrop’s taxonomy of CT activities in math and science as the reference activities. The study used Plomp’s model, started from the preliminary research, followed by the development phase and evaluation that contained the validity content and practicality evaluation. The content showed high validity scores thus it was continued with the practicality evaluation by carrying out a micro-evaluation to the target users that involved observation, interview, and questionnaire addressing. The evaluation showed that the learning activities through the student worksheet had high practicality scores thus it is possible to be used and adapted to other subject matters.

Abstract

As a branch of fundamental science, physics studies the laws underlying physical events that happen in nature. To learn physics, laboratory activity is necessarily involved, and it requires supporting devices to observe and study phenomena that are physically abstract, such as heat transfer mechanisms. This research aims to develop an Internet of Things (IoT) experiment device for heat transfer using NodeMCU and describe its working principle and measurement result. It involved NodeMCU, MAX6675 sensor, and LCD 1602 as the main components. The procedures carried out in this research included planning, developing, testing, data collecting, data analyzing, and reporting. Multiple measurements were carried out to analyze the standard error value of the device. The standard error values of both thermocouples used in the device were 1,336104 for the first thermocouple and 0,754315 for the second. Additionally, the IoT device’s thermocouple readings were calibrated using the linear regression method and the validation experiment showed that the calibration has increased its accuracy value.

Abstract

This study aims to assess the financial performance of PT Telekomunikasi Indonesia Tbk by analyzing financial statements using profitability ratios. Data collection techniques in this study use qualitative research methods with a descriptive approach. The type of data in this study is secondary data, which is obtained directly through the official website of PT Telekomunikasi Indonesia Tbk. This research received the results of the profitability ratio at PT Telekomunikasi Indonesia Tbk; namely, the development of the company's ratio cannot be said to be good because it has decreased a lot from year to year. This causes the company to be unable to generate profits because the calculation of return on assets, return on equity, gross profit margin, and net profit margin every year has decreased significantly. However, the same increase in 2021 also decreases again the following year. So it can be said that the company has not been efficient in generating profits and its financial performance also cannot be said to be good. This study aims to develop a model for reviewing financial statements from financial performance. This research is expected to make theoretical contributions to the literature in this context, including in the context of financial and banking management.

Abstract

Penelitian ini bertujuan untuk mengetahui peran orang tua dalam pendidikan anak dan pembinaan anak. Pendidikan dalam keluarga merupakan dasar bagi pendidikan anak selanjutnya, atau dapat pula dikatakan bahwa keluarga merupakan peletak dasar bagi pendidikan yang pertama dan utama. Dikatakan demikian karena segala pengetahuan, kecerdasan, intelektual, maupun minat anak diperoleh pertama-tama dari orang tua (keluarga) dan anggota keluarga lainnya. Oleh karena itu orang tua harus menanamkan nilai-nilai yang sangat diperlukan bagi perkembangan kepribadian anak-anaknya, sehingga anak akan tumbuh menjadi pribadi yang mandiri, tangguh dan memiliki sifat-sifat kepribadian yang baik pula, seperti tidak mudah marah, emosional, mampu beradaptasi dan lain sebagainya.
