The Optimal Condition of Dry-Heat Stabilization using Oven on Phenolic Content and Antioxidant Activity of Rice Bran: A Meta-Analysis

Rice bran, a beneficial by-product of rice milling, is a rich source of nutrition, containing bioactive compounds such as phenolic compounds and exhibiting high antioxidant activity. Due to these properties, rice bran is a valuable ingredient for functional foods and animal feed. However, its short shelf life caused by rapid rancidity often hinders its use. Dry heating is an effective method to increase the longevity of rice bran. It can be stabilized by heating rice bran to the appropriate temperature, retaining its nutritional value and prolonging its shelf life. This meta-analysis aimed to determine the optimal temperature and time duration for dry-heat stabilization using an oven on Free Phenolic Content (FPC), Bound Phenolic Content (BPC), Total Phenolic Content (TPC), and Antioxidant Activity (AA) of rice bran. A total of 7 articles and 34 experiments were included after applying specified screening criteria. Results indicated that temperature and time duration of dry-heat stabilization had a significant effec

Investigating English Students’ Motivation in Speaking Class during New Normal Era

Motivation is one of the most important factors and greatly influences the learning process. The purpose of this study was to determine how the level of motivation of students in the speaking class during the new nomal era, namely the second semester students of the English Department of IAIN Bengkulu. This study used a descriptive quantitative approach. The techniques used in collecting data were questionnaire and interview. The questionnaire consists of 36 questions divided into intrinsic and extrinsic motivation. The data are presented statistically using percentage, frequency, arithmetic mean, and standard deviation division. The results showed that the mean score of intrinsic motivation (3.89) was higher than the average score of extrinsic motivation (3.39). However, the overall motivation average of 3.68 is considered a high level of motivation despite currently studying in the Covid-19 pandemic conditions. The results of this study indicate that the majority of students learn English in the speaking class because of intrinsic motivation. They actively speak and learn English because of their own inner desires. Based on the findings of this study, several relevant learning implications and useful motivations are recommended to increase student motivation

Pengaruh Frekuensi Pemberian POC Hasil Biokonversi Lalat Hermetia illucens terhadap Produksi Hijauan, Rasio Daun Batang, dan Rasio Tajuk Akar Rumput Pennisetum purpureum cv. Mott

Penelitian ini bertujuan untuk mengetahui pengaruh frekuensi pemberian pupuk organik cair hasil biokonversi lalat Hermetia illucens terhadap produksi hijauan, rasio daun batang, dan rasio tajuk akar rumput gajah mini (Pennisetum purpureum cv. Mott). Penelitian ini dilakukan di Lahan Laboratorium Tanaman Makanan Ternak, Fakultas Peternakan, Universitas Padjadjaran pada Januari sampai Maret 2021. Penelitian ini merupakan penelitian eksperimental dengan menggunakan metode Rancangan Acak Lengkap (RAL) yang terdiri atas 4 perlakuan dengan 5 ulangan sebagai berikut :  frekuensi 1 kali pemupukan (P1), frekuensi 2 kali pemupukan (P2), frekuensi 3 kali pemupukan (P3), dan frekuensi 4 kali pemupukan (P4). Hasil analisis statistik menunjukkan bahwa frekuensi pemberian POC berpengaruh nyata (P0,05) terhadap berat kering daun, batang, dan tajuk rumput gajah mini. Frekuensi pemupukan sebanyak 2 kali (P2) merupakan hasil yang terbaik untuk produksi hijauan, rasio tajuk akar, dan rasio daun batang rumput gajah mini
