Learning is a process of communication between students, teachers and teaching materials. The delivery of learning messages from teachers to students is currently still using teaching aids in the form of books. This makes students less interested and feel bored when absorbing lessons, so that it gives the effect of being lazy to learn. This study designed mobile based 2D animation as an interactive learning tool for learning materials for human organs based on mobile android. This study uses the waterfall method in conducting research which includes the stages of planning, analysis, design, implementation and testing. Based on the research results, this 2D animation learning media makes it easy for students to study material about human organs that cannot be seen directly. This animation has several elements such as text, audio, video and animated images so that it attracts students' attention to feel happy in learning compared to conventional ways

Roti mocaf merupakan  produk roti yang menggunakan  mocaf (modified cassava flour) sebagai substitusi  tepung terigu. Penggunaan mocaf  dimaksudkan sebagai salah satu diversifikasi pangan. Salah satu tahapan penting pada pembuatan roti ini adalah proofing. Proofing merupakan waktu istirahat yang diperlukan adonan untuk mengembang, yang dapat dilakukan dengan cara menutup dengan plastik atau dengan memberikan uap air dalam alat rak pengistirahatan. Penelitian pendahuluan telah dilakukan terhadap lama waktu proofing (10, 15  dan 20 menit) yang diperlukan hingga roti dapat mengembang sempurna. Dari penelitian pendahuluan didapatkan bahwa  proofing optimum dilakukan  selama 20 menit. Penelitian ini dilakukan dengan menggunakan Rancangan Acak Lengkap (RAL) dengan 2 faktorial, Faktor pertama penggunaan tepung mocaf sebesar 10 ; 20  dan 30 % , faktor  kedua adalah perlakuan  proofing, yaitu  menggunakan uap air  dan  menggunakan plastik.  Roti mocaf yang dihasilkan dilakukan pengujian terhadap warna, rasa,tektur dan kesukaan secara keseluruhan roti  baik menggunakan panelis maupun menggunakan alat. Data yang didapat dianalisis menggunakan Anova dengan taraf perbedaan 5%. Apabila di antara perlakuan berbeda nyata maka pengujian dilanjutkan dengan menggunakan Duncan Multiple Range Test  (DMRT).Hasil penelitian menunjukkan bahwa   perlakuan proofing dengan cara uap air  dan cara ditutup plastik  pada pembuatan roti mocaf tidak berbeda nyata pada rasa, tekstur, warna dan kesukaan secara keseluruhan baik secara uji inderawi maupun dengan menggunakan alat.Kata Kunci :  Roti mocaf ; proofing ;  cara uap air ABSTRACT Mocaf bread is a bread product that uses mocaf as a substitute for wheat flour. The use of mocaf is intended as one of food diversification. One of the important steps in making bread is proofing. Proofing is the time needed for the mixture to expand, which can be done by covering with plastic or by providing water vapor in the resting shelves.Preliminary research has been carried out on the length of proofing time (10, 15 and 20 minute), which was needed until the bread can expand perfectly. From preliminary research it was found that the optimum proofing was carried out for 20 minutes. This research was conducted using a randomized complete design with 2 factors,  first factor was  the  use of  mocaf flour with ratio of 10: 20 and 30 precent, second factor was proofing treatment, that was using water vapor method and using covering plastic method.Mocaf bread produced  was tested for color, taste, texture and overall preference for bread both using panelists and using equipment. Data obtained was analyzed using analysis of variances with significance of 5%. If there is a significance difference then it was analyzed using Duncan Multiple Range Test (DMRT).Results of research showed that proofing treatment by water vapor method and plastic cover did not significantly affect on taste, texture, color and overall preference of mocaf bread, as evaluated by sensory and physical test.   Keywords : Mocaf bread ; proofing ;  steam methode

Virgin Coconut Oil (VCO) adalah bahan alami yang memiliki sifat antimikroba (antivirus, antibakteri, dan antijamur). Sehingga VCO dapat memberikan efek pengawet pada bahan makanan, salah satunya adalah roti manis. Penelitian ini dilakukan untuk mengevaluasi pengaruh VCO terhadap karakteristik (fisik dan kimia) dan umur simpan roti manis. Roti manis dianalisis secara fisik (tekstur dan porositas) dan kimia (kadar air, kadar abu, kadar lemak, kadar protein, dan kandungan karbohidrat), dan analisis umur simpan dengan FFA, uji organoleptik dan jamur setiap dua hari selama delapan hari penyimpanan di suhu ruang. Variasi perlakuan roti manis adalah dari rasio konsentrasi VCO: margarin: mentega, K (0%: 8%: 8%); A (4%: 6%: 6%); B (8%: 4%: 4%), C (12%: 2%: 2%); D (16%: 0%: 0%). Hasil penelitian menunjukkan bahwa VCO tidak memiliki pengaruh yang signifikan terhadap karakteristik fisik dan karakteristik kimia roti manis. Namun, VCO berpengaruh signifikan terhadap kadar air roti manis yang dihasilkan, roti manis K memiliki kadar air tertinggi (22,36%) dan berbeda dengan sampel roti manis lainnya. VCO secara efektif menghambat pertumbuhan jamur di roti manis pada konsentrasi 8%, 12%, dan 16%. Roti manis K dan A memiliki masa simpan 4 hari, sedangkan roti manis B, C, dan D memiliki masa simpan 6 hari.Kata kunci: VCO, roti manis, karakteristik, umur simpanABSTRACTVirgin Coconut Oil (VCO) is a natural ingredient that has antimicrobial (antiviral, antibacterial, and antifungal) properties. So that VCO can provide a preservative effect on food ingredients, one of which is sweet bread. This research was conducted to evaluate the effect of VCO on characteristics (physical and chemical) and shelf life of sweet bread. Sweet bread was analyzed physically (texture and porosity) and chemistry (moisture content, ash content, fat content, protein content, and carbohydrate content), and shelf life analysis with FFA, organoleptic and mold tests every two days for eight days of storage at ambient temperature. Treatment variations of sweet breads is from the ratio of the concentration of VCO: margarine: butter, K (0%: 8%: 8%); A (4%: 6%: 6%); B (8%: 4%: 4%), C (12%: 2%: 2%); D (16%: 0%: 0%). The results showed that VCO did not have a significant effect on the physical characteristics and chemical characteristics of sweet bread. However, the VCO has a significant effect on the water content of the sweet bread produced, sweet bread K has the highest moisture content (22,36%) and it is different from other sweet bread samples. VCO effectively inhibits the growth of sweet bread mold at concentrations of 8%, 12%, and 16%. K and A sweet bread has a shelf life of 4 days, while sweet breads B, C, and D have a shelf life of 6 days.Keywords: VCO, sweet bread, characteristics, shelf life
