Abstract

Penelitian ini didorong oleh pentingnya pengetahuan mengenai alat-alat laboratorium pada pelaksanaan praktikum. Tujuan dari penelitian ini yaitu membuat desain pembelajaran dengan menerapkan model pembelajaran team games tournament (TGT) menggunakan media monopoli kimia mengenai alat-alat laboratorium dengan mengacu pada indikator kelayakan yaitu hasil uji validasi. Penelitian ini menggunakan tahapan metode design based research yang meliputi tiga tahapan, yaitu analisis, perancangan, dan pengembangan. Produk yang dihasilkan berupa rencana pelaksanaan pembelajaran (RPP) dan perangkat tes untuk mengukur pengetahuan siswa mengenai alat-alat laboratorium. Hasil uji validasi terhadap rencana pelaksanaan pembelajaran (RPP) dan perangkat tes sudah memenuhi syarat (valid), dengan nilai rata-rata rhitung untuk RPP sebesar 0,77 dan perangkat tes sebesar 0,75.

Abstract

This study aimed to describe the appearance of the KIT making, how to use the KIT, and the validation test results for the making of a simple LED spectrophotometer for the analysis of iron metal ions in water. The method used was Design Based Research. This method refers to the ADDIE model, which consists of analysis, design, development, implementation, and evaluation stages. However, researchers only used the model until the development stage, starting from collecting references (journals), making concept analysis, concept maps, flowcharts, and storyboards, and the validation test of the three validators. The results from the KIT development stage could be carried out well, resulting in a valid product with indicators that include an attractive display of the KIT, easy to use, low cost, and KIT made of safe materials. The results of the validation test obtained an average value of 0.83, greater than the critical value of 0.30. This shows that the simple LED spectrophotmeter experiment KIT is valid for a feasibility test. In learning, the use of KIT refers to the spectrophotometric material which is based on the Lambert-Beer law and the analysis results that will be produced are in the form of a comparison curve of normal intensity with a wavelength in units of nanometers (nm).

Abstract

The purpose of this study to describe the view worksheet based guided inquiry, and analyze the results of the validation test worksheet based guided inquiry Fe metal biosorption in well water using citric acid modified paper waste. The method used in this research is Design Based Research (DBR) using the ADDIE development design (analysis, design, development, implementation, and evaluation) which is done up to Development stage. The instruments used were worksheet grids, worksheets, and validation test filled out by three expert validators. The result of worksheet validation test is that the mean count is 0.80, the highest count being 0.916 and the lowest count being 0.75. Guided inquiry based worksheets are declared valid and ready to be used to support the learning process.

Abstract

This study aims to analyze the validation test results and describe project-based worksheet products' appearanceon the utilization of red dragon fruit peel (Hylocereus costaricensis) waste for natural dye patchwork. The researchmethod used is Design-Based Research (DBR). The stages of this DBR method use the ADDIE design, whichconsists of 1) Analysis, 2) Design, 3) Development, 4) Implementation, and 5) Evaluation. The instruments usedwere worksheets, worksheet grids, validation sheets, and validation questionnaires filled in by three validators.The validation test percentage in this study was 86%, with a value of 0.86 obtained. Thus it can be concluded,learning media using project-based worksheets is declared valid.
