Pelatihan Penggunaan Mesin Sablon Botol Untuk Pelaku UMKM Makanan Minuman Ringan Di Kota Pasuruan

One way to attract consumers to buy products is through attractive packaging. Therefore, this community service (SSI) aims to provide training related to packaging polishing using screen printing for small scale industry actors in the city of Pasuruan. Specifically, the purpose of writing this article is to describe the implementation and results of bottle screen printing training as a form of community service for food and beverage business actors in the city of Pasuruan. The method implemented is divided into three main stages, namely analysis as well as preparation, implementation, and evaluation. The team collaborated with the Demer sablon company, Pasuruan city to provide screen printing training materials. In the training session, many participants were enthusiastic about asking questions and greatly appreciated the training activities. Also, in the practice of screen printing, many participants produced good screen prints in the first trial (84%), while others (16%) produced ordinary screen prints. It can be concluded that community service activities through bottle screen printing training for SSI actors in the city of Pasuruan are very useful and increase the knowledge and basic skills of participants on how to screen print packaging bottles manually.

Electrochemical Detection of Dopamine at Fe3O4/SPEEK Modified Electrode

Reported here is the design of an electrochemical sensor for dopamine (DA) based on a screen print carbon electrode modified with a sulphonated polyether ether ketone-iron (III) oxide composite (SPCE-Fe3O4/SPEEK). L. serica leaf extract was used in the synthesis of iron (III) oxide nanoparticles (Fe3O4NPs). Successful synthesis of Fe3O4NP was confirmed through characterization using Fourier transform infrared (FTIR), ultraviolet–visible light (UV–VIS), X-ray diffractometer (XRD), and scanning electron microscopy (SEM). Cyclic voltammetry (CV) was used to investigate the electrochemical behaviour of Fe3O4/SPEEK in 0.1 M of phosphate buffer solution (PBS) containing 5 mM of potassium ferricyanide (III) solution (K3[Fe(CN)6]). An increase in peak current was observed at the nanocomposite modified electrode SPCE-Fe3O4/SPEEK) but not SPCE and SPCE-Fe3O4, which could be ascribed to the presence of SPEEK. CV and square wave voltammetry (SWV) were employed in the electroxidation of dopamine (0.1 mM DA). The detection limit (LoD) of 7.1 μM and 0.005 μA/μM sensitivity was obtained for DA at the SPCE-Fe3O4/SPEEK electrode with concentrations ranging from 5–50 μM. LOD competes well with other electrodes reported in the literature. The developed sensor demonstrated good practical applicability for DA in a DA injection with good resultant recovery percentages and RSDs values.

Combined Paper-Based Substrates for Electrochemical Detection of Copper Ions in Serum

<p>The electroanalytical field has exploited great advantages in using paper-based substrates, even if the word “paper” might be general. In fact, the mainly adopted paper-based substrates are often chromatographic and office ones. They are characterized by main features (and drawbacks): chromatographic paper is well-established for storing reagents/treating samples but the sensitivity compared to traditional screen-printed is lower (due to porosity), while office paper represents a sustainable alternative to plastic (with similar sensitivity) but its porosity is not enough to load reagents. To overcome the limitations that might arise due to the adoption of a type of individual paper-based substrate, herein we describe for the first time, the development of a 2D merged paper-based devices for electrochemical copper ions detection in serum. In this work we report a novel configuration to produce an integrated all-in-one electrochemical device, in which no additional working media has to be added by the end user and the sensitivity can be tuned by rapid pre-concentration on porous paper, with the advantage of making the platform adaptable to real matrix scenario. The novel architecture has been obtained by combining office paper to screen-print a sustainable and robust electrochemical strip, the printed electrochemical strips and chromatographic one to 1) store the reagents, 2) collect real sample and 3) pre-concentrate the analyte of interest. The novel sensing platform has allowed to obtain a detection limit for copper ions down to 5 ppb in all the solutions that have been interrogated, namely standard solution and serum, and a repeatability of ca. 10% has been obtained.</p>

Penyuluhan Seni Branding dan Identitas Kelompok Seni “Adhikari Creations”

Adhikari Creations adalah sebuah UMKM kerajinan tangan yang memproduksi produk-produk sablon manual dengan diterapkan pada bantal, wall art, planter, dan bucket dengan visual yang umumnya berupa decorative quotes. Segmentasi pasar dari produk-produk Adhikari Creations adalah penggemar decorative quotes di mana umumnya adalah masyarakat menengah ke atas. Selain melayani pesanan perorangan, sejumlah pelanggan korporat juga menjadi pelanggan tetap dari Adhikari Creaton. Dalam mempromosikan produknya, Adhikari Creations memanfaatkan sosial media Instagram sebagai media utamanya. Walaupun sudah dikenal masyarakat, Adhikari Creations masih belum memiliki logo yang konsisten. Pemosisian diri sebagai white label company dan penitikberatan pada produksi membuat penanganan branding tidak menjadi prioritas. Selain itu, penggunaan logo yang tidak konsisten juga disebabkan oleh ketiadaan dokumen standar sistem identitas untuk menjaga konsistensi identitas. Walaupun memposisikan diri sebagai white label company, namun branding dan identitas tetap diperlukan konsistensinya untuk keperluan-keperluan yang berkaitan dengan perangkat teknis administratif seperti stempel, kop surat, maupun nota. Dari permasalahan tersebut, pengabdian masyarakat ini menawarkan solusi berupa penyuluhan seni mengenai pentingnya branding dan identitas, serta pendampingan dalam redesain logo untuk menghasilkan logo yang dapat digunakan secara konsisten. Adhikari Cretions is a handicraft home industry that produces manual screen print products showing decorative quotes that applied on pillows, wall art, planters, and buckets. Market segmentation of Adhikari Creations are decorative quotes enthusiast, upper middle class, and some corporates. To promote its products, Adhikari Creations shows their products mainly on Instagram. Although it already well known amongst certain groups of people, Adhikari Creations do not have consistent logo. Adhikari Creations positioned itself as white label company, so for it, branding is least priority. Beside those things, the lack of document for branding system standards causes this inconsistency. Although branding and identity can be prioritized less, especially for white label companies, it still important for some administrative purpose e.g. header for letters, stamp, and invoices. From that problems, this community service offers solution in form of art counseling about importance of branding and identity, also accompaniment in logo redesign to make a new logo that will be used consistently.

Artwork

I am a recreational artist from Saskatoon, Saskatchewan. My participation in art classes predates my teenage years and has had a great influence on my growth as an artist. I enjoy a wide variety of fine art disciplines and mediums, including film/digital photography, printmaking, drawing, chalk pastels, acrylic painting, pottery & sculpture. I continue to create works of art and display them on Instagram and on my art website. My work “Express Yourself” is a monotype screen print. This involves painting on a screen and transferring the image through the screen onto paper to create a one-of-a-kind print. I enjoy the freedom that this method of printmaking provides. The colours and the loose impressionistic style of this work were inspired by my favourite artist -- Claude Monet.

Screen-Printed NiO-YSZ Thin Film Electrode for Solid Oxide Electrochemical Cell and Subsequent Reduction to Ni-YSZ

Nickel and yttria-stabilized zirconia (Ni-YSZ) ceramic-metal composite electrodes are commonly used for solid oxide electrochemical cells because of their good ionic and electronic conductivity. In this study, a thin film of NiO-YSZ was prepared via screen-print method and subsequently reduced to Ni-YSZ. The precursor powder for screen-printing was prepared via glycine-nitrate combustion process. The effect of precursor particle size and of the use of PVP as binder on film uniformity and quality were investigated. For the NiO-YSZ film, scanning electron microscopy (SEM) micrographs and X-ray diffraction (XRD) patterns confirmed that size reduction and the use of binder both improved the quality and uniformity of the deposit without changing the composition of the sintered film. SEM with energy-dispersive spectroscopy (EDS) showed elemental mapping of unreduced and reduced films, revealing micro grain size faceted particles of NiO and Ni, while smooth and much larger YSZ grains were also observed. XRD of reduced Ni-YSZ film revealed that the NiO peaks had been replaced by Ni.
