Abstract

Doughnuts are one of the most popular sweet foods for people of all ages around the world. Although made from simple ingredients such as flour, sugar, eggs, yeast, milk powder, salt, water, and margarine, however producing doughnuts requires special techniques to produce good-quality doughnuts. It needs more energy, even physically and electrical equipment. A workshop on doughnut production with autolyze method for Dharma Women Association, Faculty of Engineering, University of Riau, was conducted to increase the knowledge and skills of members of the organization in making healthy dishes for the family. In this workshop, doughnuts were made using the autolysis method, which is mixing bread flour with water and then keeping the dough until gluten was formed. The formation of gluten is one indicator of the formation of smooth, soft, and elastic dough. The workshop results showed high interest among the Dharma Women Association members in making doughnuts with this alternative method.

Abstract

Bioplastics are destructive plastics that break down by the environment, humidity, and microorganism activity. Bioplastics can be used just like conventional plaques. Bioplastics include natural polymers made from plant and animal materials. Tapioca flour is pure starch obtained from the extraction of cassava milling and continues to amylose and amylopectin. Maize flour is flour obtained by grinding clean and good corn kernels through the process of obtaining skin, endosperms, institutions, and the tip of the hat. This research helps make bioplastics using tapioca flour as an adhesive and cornstarch as an efficient thickener. The use of tapioca flour and cornstarch in producing bioplastics was using the blending method. Variations in the amount of acetic acid were 2 ml, 4 ml, and 6 ml, the amount of glycerin was 2 ml, 4 ml, and 6 ml, and tapioca flour and cornstarch were 6 gr at 700oC. Bioplastics are made by mixing 6 gr tapioca flour and 6 gr cornstarch, 50 ml distilled water, and heated to a temperature of 700oC. Bioplastic test results announced by the fourth bioplastic (2.649 MPa), the best thickness possessed by the ninth bioplastic (0.12 mm), the best resistance needed by the eighth bioplastic (46.15%), and the fastest or best degradation time by bioplastics three and ninth (6 days). The effect of using glycerin is very dominant in the test results but not for the use of acetic acid.

Abstract

Chitin contained in shrimp shells can be used as raw material for making chitosan which is then reprocessed into nanoparticle-sized chitosan which has many benefits. This study aims to synthesize nanoparticle chitosan using the ionic gelation method and determine the effect of variations in the concentration of formic acid, sodium tripolyphosphate (TPP), chitosan, and the volume ratio of chitosan: TPP on particle characteristics, which include particle size, polydispersity index, zeta potential, particle morphology, and functional groups of particles. The first step for making nanoparticle chitosan is to make a chitosan solution using a magnetic stirrer. After that, the TPP solution at a certain volume ratio between chitosan: TPP was added to the chitosan solution. Stirring is carried out for 1 hour with a stirring speed of 1200 rpm. Furthermore, the nanoparticle chitosan was characterized by using Particle Size Analyzer (PSA), zeta potential analyzer, Scanning Electron Microscopy (SEM), and Fourier Transform Infra-Red (FTIR). The synthesis of nanoparticle chitosan using the ionic gelation method has been successfully carried out, obtaining a particle size of 464.4 nm, a polydispersity index of 0.214, a zeta potential of +0.48, and a cross-link of chitosan-TPP particles is formed.

Abstract

Bahan pengawet adalah sejenis bahan tambahan yang sudah digunakan secara umum oleh masyarakat. Penambahan bahan pengawet pada berbagai jenis makanan memiliki tujuan untuk mencegah tumbuhnya bakteri pembusuk, baik pada bahan mentah maupun produk akhir. Penggunaan bahan pengawet sejauh ini tidak memperhatikan dosis dan jumlah asupan yang ditambahkan sehingga sering menjadi pemicu gangguan kesehatan. Namun banyak produsen makanan yang sering melakukan penyalahgunaan penambahan bahan pengawet bersifat toksik dan karsinogenik ke dalam bahan pangan, sehingga perlu adanya edukasi dan sosialisasi cara mendeteksi secara sederhana zat pengawet yang ada dalam pangan pada masyarakat terutama di Yayasan Al-Anshar. Hal ini karena yayasan Al-Anshar memiliki badan usaha sendiri yang mampu memproduksi berbagai jenis makanan seperti: berbagai jenis roti, bakso, tahu dan makanan ringan lainnya. Kegiatan pengabdian ini diawali dengan edukasi dan sosialisasi mengenai jenis-jenis bahan pengawet pada makanan. Hasil kegiatan menunjukkan bahwa edukasi bahan pengawet pada produk makanan dapat meningkatkan pengetahuan dan pemahaman peserta pelatihan sehingga mampu melakukan analisis dengan metode sederhana dalam mendeteksi bahan pengawet yang berbahaya seperti formalin dan boraks.

Abstract

This research aimed to produce biodiesel from off-grade palm oil using barium hydroxide (Ba(OH)2) catalyst. The free fatty acid (FFA) content in off-grade palm oil is quite high, so the biodiesel production process is carried out in two-stages, i.e. esterification and transesterification. The esterification of off-grade palm oil (500 mL) was carried out at 60 oC for 1 hour, methanol:oil molar ratio of 12:1, stirrer speed of 400 rpm, and 1 wt-% sulfuric acid (H2SO4) as the catalyst. Next, the transesterification process used a methanol:oil molar ratio of 9:1, stirrer speed of 400 rpm, for 2 hours with the variation of temperatures (50, 60, and 70 oC) and Ba(OH)2 catalyst amounts (1, 2 and 3 wt-%). The best result was obtained with 60 oC and Ba(OH)2 catalyst amount 3 wt-%. Based on Gas Chromatography-Mass Spectroscopy (GC-MS) analysis, the best yield of fatty acid methyl ester was 98.97%, with major components being 40.87% palmitic acid and 35.87% oleic acid. The characteristics of biodiesel produced were density of 860.46 kg/m3, viscosity of 4.08 mm/s2, flash point of 145 oC and acid value of 0.457 mg KOH/g biodiesel.
