Abstract

Many kinds of learning methods for early age level in stimulate all aspects of its development. One of the methods is karyawisata method. With this method the children directly faced with concrete objects that corresponds to its development stage. In addition to play and and imagine, early children have extraordinary creativity level. In this study researchers want to know how much the influence of karyawisata method against the ability of creativity of early childhood (kindergarten) through activities such as drawing. Where the drawing included in the learning achievement indicator on the Fine motoric aspects. this study use the quantitative approach and analysis technique with product moment in order to measure the scale of "influence" against two variables variable X as bound namely karyawisata method and a variable Y as free namely creativity. While the population is all the students of class B kindergarten of bani Toifur Nganjuk Regency. From the collected data and data processing obtained the result that the table of the value of the "r" product moment with df of 18, on the rank of the significance of 5 percent obtained r_table = 0,444. Because the r_xy on the rank of the significance of 5 percent greater than r_tables, 0.47 > 0,444 dors to write it on the rank of the significance of 5 percent zero hypothesis was rejected, while the alternative hypothesis is received. This means that between both variables X and Y is the influence of the karyawisata method against creativity drawing children in kindergarten of Bani Toifur there is a significant positive correlation.

Abstract

Kulit pisang merupakan limbah organik yang berpotensi tinggi sebagai sumber kalium alami untuk pembuatan pupuk ramah lingkungan. Penelitian ini bertujuan untuk mengetahui pengaruh jenis kulit pisang terhadap kandungan kalium yang dihasilkan pada proses sintesis pupuk nano kalium sulfat (K₂SO₄). Bahan yang digunakan terdiri atas tiga jenis kulit pisang, yaitu kulit pisang kepok, pisang raja, dan pisang raja nangka. Masing-masing sampel diekstraksi dan disintesis menjadi nano K₂SO₄ melalui proses presipitasi, kemudian dikarakterisasi menggunakan X-Ray Fluorescence (XRF) untuk menentukan komposisi unsur, serta didukung dengan analisis Scanning Electron Microscopy (SEM) untuk mengamati morfologi partikel. Hasil analisa XRF menunjukkan bahwa kulit pisang kepok memiliki kandungan kalium tertinggi sebesar 50,6% dan sulfur sebesar 49%, dengan kadar pengotor logam yang rendah (Fe 0,07% dan Cu 0,2%). Kulit pisang raja dan pisang raja nangka menunjukkan kandungan kalium masing-masing 29,1% dan 37%, disertai adanya unsur molibdenum (Mo) yang cukup tinggi. Berdasarkan hasil tersebut, dapat disimpulkan bahwa jenis kulit pisang kepok menghasilkan pupuk nano kalium sulfat dengan kandungan kalium paling tinggi dan kemurnian terbaik, sehingga paling potensial digunakan sebagai bahan dasar pembuatan pupuk nano berbasis K₂SO₄.
