Development of Occupational-based-Context Worksheets of Geometric Sequences and Series for Senior High School Students
Get PDFMathematics activities should not just be a procedural problem. It should be presented in context, especially real-life contexts that students often encounter. One of the contexts that many students encounter in their daily lives is occupational context. By completing contextual-mathematical-activities, students do not just solve problems procedurally, but they need to understand the underlying mathematical-concepts so that they are able to identify what is known and what is being asked correctly, so that students are able to determine the right steps and formulas to apply in solving problems. Therefore occupational-context is potential to be used in developing mathematical activities. One of them is in learning concept of Geometric Sequences and Series. The use of occupational-context could help students understand the use of mathematical concept so it can help students gain better understanding on the concept they learnt. Therefore in this study it is developed students’ worksheet (LKPD) based on occupational-context for concept of geometric sequences and series. Research method used is Research and Design (R & D), by applying ADDIE model, consist of analysis, design, development, implementation and evaluation stages. Result of this study shows that LKPD developed is valid and practical to be implemented in actual classroom. The implementation of the LKPD shows that LKPD is effective in helping students learn and understand the concept of geometric sequences and series. Furthermore, students give good responses for the use of LKPD. This is implied by the average percentage of students’ responses is 82.67%

Iot Based Heart Rate Detector Design
Get PDFHeart rate is a very vital part of the human body, if the heart rate exceeds the maximum limit it will be very dangerous for the body. So we need a heart rate recording device that can store heart rate recording data so that it makes it easier to control health. This study aims to test the heart rate recording system with a comparison of a factory-made device, namely an oximeter. Making measuring instruments consists of making hardware and making software. In making hardware, several components are used, namely pulse sensors, NodeMCU, Oled and the device for making software is the Arduino IDE. Testing of the heart rate detection device is carried out by placing a pulse sensor at the tip of the finger to measure the heart rate of respondents of different ages. The test results show that the measuring tools that have been made show that manual calculations and using tools have fairly good accuracy. The results of the data obtained from the test were 60% (3 out of 5 people) who had the same heart rate using either a device or an oximeter. The average accuracy value of the heart rate recording system when compared to an oximeter is relatively small, namely 1-2 bpm

Response Of Giving Antagonist Fungi Trichodema Spp On Vegetative Growth Of Soybean Plants (Glycine max (L) Merr.) Infected By Fusarium Sp.
Get PDFBiological control is the use of antagonistic agents to control plant pathogens. One of the biological agents currently being developed is Trichoderma spp. Trichoderma spp fungi are often used to control Fusarium sp (root wilt disease). Trichoderma spp fungi have the ability to increase the growth rate and development of plants, especially their ability to cause healthy root production and increase root depth (deeper in the soil surface). Therefore, the author aims to examine the response of Trichoderma spp antagonistic fungi to the vegetative growth of soybean plants (Glycine max (L) Merr.) Infected with Fusarium sp. This study was conducted using an experimental method using a single factor Completely Randomized Design (CRD) consisting of T0F0, T0F10, T10F10, T15F10. Each consists of 4 replications. The results of the study showed that Trichoderma spp played a significant role in the process of inhibiting the growth of Fusarium sp in root development, plant height, development of the number of leaves and functioned to provide nutrients for plants causing plant cell metabolism to run better so that plant growth during the vegetative phase did not experience obstacles.

THE INFLUENCE OF IMPORT EXPORTS ON ECONOMIC GROWTH FROM AN ISLAMIC PERSPECTIVE
Get PDFThe significance of promoting exports in order to boost national income and promote economic growth. The community grows rich as economic income rises. Additionally, exporting helps the nation create foreign exchange, which is subsequently utilized to fund its needs for development. The high rate of economic growth that can be attained through import and export operations is a sign of a successful and well-represented nation. Islam's perspective on the economy is based on the actions of the Prophet Muhammad SAW, his relatives, and associates who engage in cross-border trade in the Arabian Peninsula, Yemen, Bahrain, Syria, and other border regions. The issue occurs when exports prove to be less than imports, which results in a negative trade balance, a drop in the value of the currency, and a reduction in people's purchasing power, all of which have an impact on economic growth. Using the literature review method, this essay will examine how imports and exports affect economic growth from an Islamic perspective
