This research was a development research with a mix method approach. This study aimed to develop augmented reality learning media that was used to help students visualize three-dimensional mathematical objects. It important research because could replace the use of teaching tools that were limited in number, so they could assist teachers in learning process. This research was based on the Plomp model so that it consists of four phases as the following: (1) Preliminary assessment; (2) Designing; (3) Realization; and (4) Tests, Evaluations, and Revisions. The purpose of this study was to examine the validity, implementation, and effectiveness of augmented reality media. The results of this study revealed that augmented reality media was valid to use based on the results of expert validation, practical to use based on the observation sheet of teacher learning and response implementation, and effective to use based on learning outcome tests and student response questionnaires.
This study aims to determine the effect of profitability, liquidity, firm size, sales growth, and dividend payout ratio on capital structure. The sampling technique uses purposive sampling method so that a sample of 28 property and realestate companies are listed on the Indonesia Stock Exchange during the 2013-2017 period. The type of data used is secondary data in the form of annual financial statements of property and realsetate companies in 2013-2017. Data analysis method used is multiple linear regression analysis using SPSS version 20. The results of this study indicate that partially profitability proxied by net profit margin (NPM) does not affect the capital structure, liquidity is proxied by the current ratio (CR) effect on the capital structure, the size of the company which is proxied by total assets (Ln TA) does not affect capital structure, sales growth that does not affect the capital structure, dividend payout ratio does not affect the capital structure. Simultaneously profitability, liquidity, company size, sales growth and dividend payout ratio affect the capital structure
The industrial revolution 4.0 that we have faced nowadays has triggered the development of digital and cyber technology which will affect all aspects of human life, including educational aspect teaching of mathematics. Therefore, a new learning model that can be a reference for teachers in facing the industrial revolution 4.0 is needed. This article would review the flipped learning model as a form of Blended Learning (BL) in the teaching of mathematics. The flipped learning model was a learning model that conveys learning information remotely through video or text in an online context, and then the learning material would be further learnt through face-to-face learning. The implementation of this model was supported by a variety of technologies so that it was suitable to be used in the current 4.0 industrial era. In addition, this article would explain the example of implementing flipped learning in teaching mathematics that could be used as a reference for teachers. The overall description was expected to be an inspiration for researchers, teachers, or prospective mathematics teachers in conducting further research and in the process of learning mathematics.
Spons sebagai salah satu hewan primitif yang hidup menetap dan bersifat filter feeder (menyaring). Hewan tersebut memberikan sumbangan yang penting terhadap komunitas bentik laut dan sangat umum dijumpai di perairan tropik dan sub tropik. Penelitian ini bertujuan untuk mengetahui keanekaragaman dan kepadatan spons di Perairan Lalowaru, Kabupaten Konawe Selatan. Pengambilan data ini dilaksanakan pada bulan April-Agustus 2016. Pengambilan data spons dilakukan dengan metode transek kuadrat. Garis transek sepanjang 50m dibentangkan tegak lurus pantai yang mewakili kondisi perairan pada kedalaman yang berbeda. Kemudian transek kuadrat ukuran 1m2 diletakkan dengan jarak 5m disetiap pengulangannya. Didapatkan bahwa keanekaragaman jenis spons di Perairan Lalowaru sebanyak 7 famili yaitu Agelasidae, Callyspongidae, Chalinidae, Irchinidae, Petrosiidae, Pseudoceratinidae, dan Microcionidae, 7 genus yakni Agelas , Callyspongia , Chalinula , Ircinia , Xestospongia , Pseudoceratina , dan Clatrhia . dan 243 individu. Kepadatan spons dilokasi penelitian dengan nilai kepadatan tertinggi terdapat pada genus spons Xestospongia dengan nilai 15,34 ind/10m² dan terendah genus Pseudoceratina dengan nilai 0,34 ind/10m².Kata kunci : Keanekaragaman, Kepadatan, Spons, Perairan Lalowaru
The purpose of this study is to identify and design an Information System for the Use of Heavy Equipment at the Department of Highways with the programming languages HTML, PHP, CSS, JSON, AJAX and MySQL as database support. Broadly speaking, this research is divided into three stages, namely pre-development data collection, development and implementation, and post-development data collection. While in software development using the DSRM (Design Science Research Method). From the results of the study, it can be concluded that the information system on the use of heavy equipment at the Aceh Bina Marga Office has followed the procedure using HTML, PHP, CSS, JSON, AJAX and MySQL programming languages as database support.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
