It is characterized by its high protein content as well as good amino acid profiles (Sanchez-Muros et al., 2014). Protein itself plays an important role in the body of livestock; it serves as building blocks for various tissues and organs, and involves in the regulatory function as an integral component of various enzymes and hormones. Our previous study demonstrated that BSF contained protein in its body of more than 40% on dry matter basis (Jayanegara et al., 2017a). Other studies reported that the crude protein content of BSF ranged from 38.3 to 58.8% (Marono et al., 2015; Oonincx et al., 2015; Spranghers et al., 2017). Apart from its high protein content, BSF has other additional advantages in which it grows rapidly on various organic substrates (Spranghers et al., 2017), and does not provide any adverse effect on environment and human health. Despite all of its potency, BSF contains considerable amount of chitin that may limit its use as animal feed. Chitin is a polymer of N-acetylglucosamine and typically present in substantial amount in insects. It had been reported that chitin content of BSF ranged from 8.7 to 9.6% (Diener et al., 2009; Kroeckel et al., 2012). Chitin is insol

Namun adanya pandemik Covid-19 menyebabkan perkuliahan pada kegiatan pertukaran pelajar dilaksanakan secara jarak jauh (daring). Pembelajaran jarak jauh sering menimbulkan masalah bagi mahasiswa seperti academic burnout, stres, dan kelelahan emosional. Penelitian ini bertujuan untuk mengetahui tingkat efikasi diri mahasiswa pada kegiatan pertukaran pelajar dalam pembelajaran daring. Metode yang digunakan dalam penelitian ini adalah survei. Teknik pengumpulan data dengan menyebar kuesioner pada 20 mahasiswa dan wawancara pada 6 mahasiswa peserta kegiatan pertukaran pelajar di program studi PGSD UNS-UNY. Lima faktor untuk melihat efikasi diri dalam menyelesaikan pembelajaran daring; berinteraksi secara sosial dengan teman sekelas; menangani alat di CMS (Course Management System); berinteraksi dengan instruktur di pembelajaran daring; dan beri...

Seiring berkembangnya daerah Desa Sindangsari dengan telah selesainya pembangunan kampus salah satu PTN di sekitar desa tersebut, perlu adanya keterampilan dan kemampuan pengolahan pangan yang baik di sana. Terlebih lagi semakin banyak peluang untuk membuka usaha berbasis pangan di sekitar kampus nantinya. Tujuan kegiatan pengabdian ini adalah meningkatkan kesadaran dan pengetahuan warga Desa Sindangsari agar tercipta lingkungan yang lebih sehat dari segi pengolahan pangan. Langkah kegiatan pengabdian ini terdiri dari persiapan pelaksanaan kegiatan dalam bentuk komunikasi dengan perangkat desa setempat, pemaparan materi dan diskusi oleh dosen yang berkecimpung dalam bidang keamanan pangan, serta evaluasi hasil. Hasil pelaksanaan menunjukkan bahwa pemahaman peserta terhadap CPPB menjadi meningkat serta seluruh pe...

This study used quantitative approach with comparative design by using independent samples t test. This study involved 60 respondents by using random sampling technique. The respondents consisted of 30 parents who entrusted their children in day care and 30 parents who cared their children in their house by other members of family except parents. This study used children who were 2-4 years old in Semarang regency. The attachment was measured by using likert scale with three factors which influenced the attachment. The factors were baby sitter, children’ behavior and atmosphere of family. The result showed that there is...

These two ingredients are generally not used as the main raw material for food products and are diverted as feed ingredients due to their low nutritional content. The nutrient content that is still present in pollard and rice bran, especially fiber and anti-nutrients, is very useful for people with diabetes and obesity. The aim of this study was to analyze the effect of fractionation on nutrient content and to separate the components of pollard and rice bran using a gravity and molecular weight approach. The experimental design used was CRD (Completely Random Design) Factorial 2 × 3 × 3 for physical test data. Factor A is the material, namely pollard and rice bran, factor B is the position of the fraction, namely top, middle and bottom. Data analysis was performed by analysis of variance (ANOVA) and the significant one will be further analyzed using Duncan's test. The chemical property values were analyzed descriptively. The results showed that the value of bulk density (g l-1), compacted bulk density (g l-1), specific gravity (kg l-1), angle of purpose (o) of pollard and rice bran were significantly different (P<0.05) on all three fractions. The highest physical parameters for pollard were at the bottom fraction with the value 386.47 g g l-1 , 537.28 g l-1 , 1.42 kg l-1 , ST 46.98 o. The highest physical parameters for rice bran were at the upper fraction with the value of 394.09 g l-1 , 526.33 g l-1 , 1.50 kg l-1 , 46.01 o. Crude fiber content (%) of pollard and rice bran were the upper fractions 6.77 and 21.69, middle fractions 8.19 and 34.70, lower fractions 5.52 and 32.76. Fractionation technology can separate food ingredients based on chemical components, especially crude fiber. The physical properties of pollard and rice bran after fractionation generally improved in quality. The fraction that has the best physical and chemical quality is the lower fraction for pollard and the upper fraction for rice bran. The middle fraction has the highest crude fiber content, so it has the potential to be a raw material for making high fiber processed food.

Metode survei dan studi kasus digunakan untuk menggapai tujuan. Partisipan dalam penelitian ini adalah 79 siswa kelas empat di salah satu sekolah dasar yang ada di Bantul. Data diambil menggunakan kuesioner persepsi dan dieksplorasi lebih lanjut melalui wawancara kepada 6 siswa berdasarkan level kognisinya. Analisis deskriptif digunakan untuk menggambarkan kecenderungan data. Di samping itu, transkrip rekaman wawancara dikodekan masing-masing peneliti berdasarkan pola menarik dan kemudian didiskusikan. Triangulasi sumber digunakan untuk menjamin keakuratan hasil. Hasil penelitian menunjukkan bahwa persepsi siswa terhadap pembelajaran matematika secara daring cenderung mengarah pada persepsi negatif. Tidak menarik, membosan, tidak efektif mungkin adalah kata-kata yang tepat menggambarkan sikap mereka. Selain itu, ditemukan bahwa level kognisi tidak mesti sejalan dengan minat dan motivasi siswa. Literasi teknologi dan inovasi pembelajaran yang sesuai dengan zamannya menjadi penting untuk diperhatikan sebagai upaya memfasilitasi guru dan siswa dalam pembelajaran matematika secara daring.

Black soldier fly (BSF, Hermetia illucens) larvae is characterized by its easy production system, rapid growth, able to efficiently convert organic waste and contains high protein, i.e., around 40%. However, the BSF exoskeleton contains chitin which is a component of cell wall and may inhibit the process of nutrient utilization in the digestive tract of ruminants. This experiment aimed to reduce chitin in BSF through physical (separation of the exoskeleton part) and biological (fermentation with chitinolytic bacteria) treatments. There are four treatments tested in this study: BSF larvae control (T1), BSF larvae without exoskeleton (T2), fish meal (T3), fermented BSF larvae using Bacillus subtilis ATCC 19659 (T4).Physical and biological treatments were able to reduce crude fiber content from 20.27% (T1) to 4.29% (T2), 13.18% (T4), and there was...
