The prototype of infant incubator monitoring system based on the internet of things using NodeMCU ESP8266

Abstract: Growth parameters that parents often pay attention and monitoring for their infants are weight and temperature to determine the health condition of the infant. Parents don't realize that the size of the head circumference reflects the brain volume. The head circumference is an important thing that should always be monitored the growth to see whether the infant's brain grow and develop normally or not. Generally, doctors or midwives use a separate measuring instrument. The use of separate measuring instruments requires considerable time and digital measuring instrument. This study aims to make a tool in one system that consists of three measurement parameters including weight, temperature, and head circumference. The tool can record the parameters automatically. The parameters automatically measure the infant's weight, temperature, and head circumference to determine the condition of the infant. The tool is operated through IoT (internet of things) which can facilitate paramedic to monitor the infant's situation wherever and whenever through internet network that can be accessed via web or Android. The three parameters are controlled directly with the NodeMCU ESP8266 module using two ultrasonic sensors to determine the circumference of the infant's head, the weight sensor using load cell, and the temperature sensor using an SHT31 temperature sensor. It is expected that this tool can help the paramedic work to act quickly because it can monitor the state of the infant online.

The effect of teachers pedagogic competency on the learning outcomes of students

Abstract: This study aims to determine the effect of pedagogic competence on student learning outcomes. The population in this study were 41 students of physics class at high school in Pati. Collecting data by observation, interviews and distributing questionnaires. The questionnaire method was used to collect data on the independent variables of Pedagogic Competence and the dependent variable on Learning Outcomes. Test the research instrument by testing the validity and reliability test. The data analysis technique used is multiple regression analysis, coefficient of determination, t test and F test with a significance level of 0.05. Before analyzing the data, the analysis prerequisite test was conducted, including the normality test, multicollinearity test and heteroscedasticity test. The results of this study indicate that there is a significant influence between pedagogical competence on student learning outcomes in the learning evaluation course.

Isolation and Identification of Active Compounds from Papaya Plants and Activities as Antimicrobial

Abstract: Extraction and isolation of papaya seeds and leaves (Carica papaya L) has been performed using n-hexane and ethanol solvents. Further isolation of the extract obtained using ethyl acetate and diethyl ether solvents. The result of the phytochemicaltest of papaya extract obtained by mixture of an active compound of flavonoids, alkaloids, tannins, steroids, and saponins. Ethyl acetate isolates containing only flavonoids and diethyl ether isolates contain only alkaloids. Extracts and isolates from papaya plants had gram-positive antibacterial activity greater than the gram-negative bacteria, but both did not have antifungal activity. Papaya extracts have greater antibacterial activity than flavonoid isolates and alkaloid isolates. Strong antibacterial inhibitory sequences are extracts of papaya plants, flavonoid isolates, and alkaloid isolates.

These factors are DER, ROA, EPS company age, company size, the percentage of the stock offering. The population of this research are all Manufacturing companies listed in the Indonesia Stock Exchange 2010-2011. Sampling using purposive sampling is the selection of the sample with certain criteria, so that the sample obtained in this study were 55 companies. Multiple regression analysis was employed to analyse data. The results showed that EPS, company size, percentage of share offerings, significantly affect underpricing, while DER, ROA, and company age does not effect underpricing. The results obtained simultaneously DER, ROA, EPS, company age, company size, percentage offering significantly affect underpricing.

Pengaruh model pembelajaran discovery learning dengan mind mapping terhadap hasil belajar siswa pada materi sel di sma

Abstract: Peraturan Menteri Pendidikan dan Kebudayaan Republik Indonesia Nomor 103 Tahun 2014 tentang Pembelajaran pada Pendidikan Dasar dan Menengah disebutkan bahwa pada implementasi Kurikulum 2013 sangat disarankan menggunakan pendekatan saintifik dengan model-model pembelajaran inquiry based learning, discovery learning, project based learning dan problem based learning. Model pembelajaran discovery learning yang dipadukan dengan teknik mind mapping merupakan model yang sesuai untuk menunjang tercapainya tujuan pembelajaran pada materi sel. Penelitian ini bertujuan untuk menganalisis pengaruh model pembelajaran discovery learning dengan mind mapping terhadap hasil belajar aspek kognitif, afektif, dan psikomotor siswa pada materi sel di SMA. Penelitian ini menggunakan desain penelitian Quasi-Eksperimental tipe Posttest Only Design. Populasi dalam penelitian ini adalah seluruh siswa kelas X MIA di SMA Negeri 1 Salatiga Tahun Ajaran 2015/2016 yang berjumlah 192 siswa. Pengambilan sampel menggunakan teknik purposive sampling dan sampel berjumlah 62 siswa. Rata-rata hasil belajar kognitif yaitu 82,72 (melampaui KKM aspek kognitif yang ditetapkan yaitu 75). Hasil belajar afektif siswa menunjukkan 51,61% siswa memperoleh predikat A dan 48,38% siswa memperoleh predikat B (mampu melampaui KKM afektif yang ditetapkan yaitu B). Hasil belajar psikomotor menunjukkan 4,83% siswa mencapai nilai A, 22,58% siswa mencapai nilai A-, 59,67% siswa mencapai nilai B+, dan 12,90% siswa mencapai nilai B (seluruh siswa melampaui KKM psikomotor yang ditetapkan yaitu B). Rata-rata hasil belajar siswa yang belajar menggunakan model pembelajaran discovery learning dengan mind mapping pada materi sel di SMA melampaui Kriteria Ketuntasan Minimal yaitu 75 (P<0,05).
