Mosquito (Aedes aegypti) is a threat to human health due to its capability to spread dengue fever. Citronellal in citronella oil is one ofnatural active compound that has repellent activity. Essential oil is a sensitive material whichiseasy to degrade. Encapsulation is coating technology use to avoid essential oil from degradation problems. β-Cyclodextrin is frequently used as acoating material in encapsulation. The aims of this study wereto prepare the citronellal encapsulation and to evaluate its control-released and repellency. In this study, encapsulated citronellal was prepared using 83.65% citronellal and encapsulation were prepared with the theemulsion-based method and dried using freeze-dryer. The best-controlled release was performed in citronellal encapsulate with a weight ratio of 1:1 (citronellal : β-Cyclodextrin). The morphology of encapsulated citronellal was analyzed using SEM. SEM result showed it has three dimensions random shape and agglomerate in some part with thebrighter spot. Citronellal encapsulate showed the highest repellent effect at 84,67% for 5 minutes in mosquito repellency test although it has lower result compared with citronellal inliquid form.

The present work introduce synthesis low grade zeolite from fly ash and its application as urea slow release agent on Zea mays growth. The characterization of the synthesized zeolites were determined using X ray diffraction method and FT-IR spectroscopy. The zeolite that has been formed is added to urea fertilizer with a weight ratio of urea: zeolite as follows 1: 1, 1: 2, 1: 3. As much as 3 kg of soil is put in a polybag series and was added with 3 g urea slow release fertilizers. The polybags were planted with Zea mays plant 1 week in old at a depth of ± 5 cm. The plant growth parameters which include plant height plant, number and colour of leaves were observed every 7 days for 4 weeks Base on the diffraction pattern and IR spectra, the characteristics of the synthesized zeolite is matching with standard zeolite A. The use of urea slow release fertilizer on Zea mays plants showed better growth than using urea fertilizer without zeolite slow release ingredients. The treatment of s...

Pembelajaran abad 21 menuntut peserta didik untuk memiliki keterampilan menyeluruh. Keterampilan abad ke-21 terdiri atas empat domain utama yaitu literasi, berfikir inventif, komunikasi yang efektif dan produktivitas yang tinggi. Sebagaimana kita tahu bahwa Indonesia kemampuan literasi siswa Indonesia masih tergolong rendah. Rendahnya kemampuan literasi sains tersebut disebabkan beberapa faktor. Kesalahan dalam pemilihan sumber belajar. Bahan ajar yang dipakai sekolah belum berbasis kearifan lokal dan belum memenuhi kategori valid untuk mengukur kemampuan literasi. Untuk itu dibutukan pengembangan bahan ajar modul berbasis kearifan lokal dalam menunjang ketercapaian kompetensi serta tujuan dalam pembelajaran. Penelitian ini bertujuan untuk memperoleh suatu produk melalui proses pengujian keefektifan untuk mengukur kemampuan literasi sains, data dan lingkungan.
