Abstract

Packaging of food products using edible films plays an important role in protecting foodstuffs from microbial contamination and improving the quality of foodstuffs during storage. The addition of chitosan as an antibacterial with the aim of inhibiting pathogenic microbes that cause food contamination. This study aims to study the effect of increasing the volume of chitosan and glycerol on the characteristics of edible films. In this study, an edible film made from cassava starch-chitosan was made with various compositions of 5:5, 6:4, 7:3, 8:2 and 10:0 using the plasticizer glycerol 1; 1,2; 1.5; 1.7; and 2 ml. Furthermore, the characterization of the edible film was carried out including thickness test, water resistance test, ALT microbial test, FTIR test, and application to carrots to determine the shelf life. Edible film with a composition of 5:5 with a glycerol volume of 1 ml showed the best results, which had a thickness of 0.095 mm, water resistance 60.91%, and the number of colonies was 215 cfu/ml. In the application of edible film, carrots have a shelf life of 5 days, carrots coated with edible film still have good physique. Meanwhile, carrots that are not coated with edible film have fungal growth.

Abstract

Research on the manufacture of polyurethane as an iron coating material with an eggshell filler has been done. The purpose of this study was to determine the effect of eggshell weight as an additive on the preparation of polyurethane as an iron coating material and to determine the weight effect of Methylene Diphenyl Diisocyanate (MDI) on the manufacture of polyurethane as an iron coating material with an eggshell filler. By mixing Jatropha oil polyols, Methylene Diphenylene Diisocyianate (MDI), and eggshell, then applied to an iron plate. Polyurethane coatings formed in the analysis of thermal adhesion properties of coatings, Thermal (TGA), functional groups (FT-IR), crystal structures (XRD), and coating morphology (SEM). The results obtained which in addition to the ratio of polyol: isocyanate: eggshell shell of 7: 3: 5% obtained the best results that have the strongest adhesion and has a good mixing structure, and has a heat resistance of 300 0C

Abstract

Penggunaan pupuk kimia dalam bidang pertanian dan perkebunan untuk peningkatan kesuburan tanah, kesuburan tanaman, dan pendapatan petani perlu pengkajian ulang. Pupuk kimia selain bermanfaat juga berdampak negatif dalam jangka lama, dimana pupuk kimia dapat merusak tekstur dan struktur tanah. Oleh karena itu, pemikiran kembali ke pertanian secara alamiah dengan memanfaatkan unsur hara yang tersedia dialam guna menjaga kesuburan tanah, menekan atau menghemat biaya produksi, menjadi suatu langkah yang peting. Tujuan dari kegiatan penerapan ipteks ini adalah; 1). Memberikan pelatihan dan keterampilan kepada para petani untuk membuat pupuk kalium cair dan 2). Penggunaan pupuk kalium cair untuk pertumbuhan dan perkembangan tanaman hortikultura seperti kelapa sawit, pinang, kelapa dan coklat. Metode kegiatan melalui pendekatan teoritis, diskusi,demontrasi dan aplikatif. Pada pelaksanaannya, karena keterbatasan dana, maka peserta dibagi dalam 2 kelompok kerja. Masing kelompok terdiri dari 3 orang dimana pembuatan pupuk kalium cair berbahan baku sabut cacah dan berbahan baku tanpa cacah. Kesimpulan kegiatan:1).Kegiatan penerapan ipteks berlangsung terarah, terukur dan sesuai dengan target. Setelah mengikuti kegiatan pembuatan pupuk kalium cair terjadi peningkatan kemampuan peserta rata-rata diatas 83% dan 2). Setelah mengikuti kegiatan ini peserta berkampuan membuat pupuk kalium cair secara mandiri dan dapat menggunakannya untuk bagi usaha pertanian dan perkebunan yang mereka usahakan. Dengan tersedianya pupuk kalium cair dapat memberikan peningkatan produksi pertanian serta berdampak positip bagi pendapatan mereka.Kata Kunci: pupuk kimia, pupuk kalium cair, pertanian, pendapatan
