Abstract

The utilization of native cassava starch in the food industry is limited. It needs a modified process to increase its utilization. This study aimed to evaluate the effect of a combination of steaming and acid hydrolysis and determine the best temperature and hydrolysis time that is suitable to apply as an encapsulant in the nanoencapsulation process of cocoa leaf crude extract. Modification of cassava starch used 50 ℃, 60 ℃, and 70 ℃ temperatures for 30, 60, and 90 minutes with HCl pH 1. The result showed that modified cassava starch produced from a combination of steaming and acid hydrolysis at 70℃ for 30 minutes has the best specifications with 60.48% solubility, 12.38% hygroscopicity, pasting profile (PV=48; BV=3; FV=66; SV=21). Then, it is combined with Arabic gum and used in the nanoencapsulation process using spray drying. This study showed that encapsulation can protect phenolic compounds of cocoa leaf crude extract resulting brownish-red color surrounded by a black circle. Nanocapsule powder has 13.56% moisture content, 350.3 nm particle size, 16.93 zeta potential, and 84.30% encapsulation efficiency. The combination of steaming and acid hydrolysis at 70 ℃ for 30 minutes produces modified cassava starch which is suitable for use as an encapsulant in the nanoencapsulation process of crude extract of cocoa leaves.

The American Academy of Pediatrics, an institution that deals with the problems of school-age children in America, states that school-age children need time adequate sleep, based on research results, namely school-age children who lack sleep will experience various negative things including memory and learning disorders, physical health problems, mental health problems and are at high risk of experiencing obesity (Huda, 2016). Determine the effectiveness of the use of gadgets with sleep quality in grade IV and V children in warrior VII state elementary schools in Bekasi city.   The sample of this study is partly grade IV and V school children at SD Negeri Pejuang VII in May 2023. With Random Sampling technique.  The results of the Chi Square test showed that there was an effectiveness in using gadgets with sleep quality in school children in grades IV and V at SD Negeri Pejuang VII in 2023 with a total sample of 60 respondents and a P value of 0.00 (p 0.05). The effectiveness of using gadgets with sleep quality in grade IV and V school children at SD Negeri Pejuang VII in 2023.     Keywords: School Age Children, Use of Gadgets, Quality of Sleep  ABSTRAK Pengguna internet terbanyak (dengan mengakses gadget) di Indonesia merupakan masyarakat dalam kelompok usia 15-19 tahun. dari 171,17 juta pengguna yang menggunakan internet dan menunjukan bahwa kalangan remaja atau generasi muda yang paling banyak menggunakan internet (APJII, 2018).American Academy of Pediatris yaitu sebuah lembaga yang menangani masalah anak usia sekolah di Amerika menyatakan bahwa anak usia sekolah membutuhkan waktu tidur yang cukup, bedasarkan hasil penilitian yaitu anak usia sekolah yang kurang tidur akan mengalami berbagai hal negatif diantaranya gangguan memori dan pembelajaran, masalah kesehatan fisik, masalah pada kesehatan mental dan berisiko tinggi mengalami obisetas (Huda, 2016).  Mengetahui efektifitas penggunaan gadget dengan kualitas tidur pada anak kelas IV dan V di sekolah dasar negeri pejuang VII kota Bekasi.  Sampel penelitian ini sebagian anak sekolah kelas IV dan V di SD Negeri Pejuang VII pada bulan Mei 2023. Dengan jumlah sampel sebanyak 60 responden dan menggunakan teknik Random Sampling. The results of the Chi Square test show that there is effectiveness in using gadgets with sleep quality in school children in grades IV and V at SD Negeri Pejuang VII in 2023 with a P value of 0.00 (p 0.05). Adanya efektivitas penggunaan gadget dengan kualitas tidur pada anak sekolah kelas IV dan V di SD Negeri Pejuang VII tahun 2023. Kata Kunci: Anak Usia Sekolah, Penggunaan Gadget, Kualitas Tidur
