The Stability

In this study the effect on quality measurement introduced by input precision of instrument in image digitizing process was verified through a series experiment. Two categories of samples, which were outputted by EPSON Stylus Pro7880c digital inkjet printer and Xerox DocuColor5000 digital xerographic printer individually, were transformed into digital image with a normal flatbed scanner in 600 DPI, 1200 DPI and 1600DPI resolution. The area quality attributes such as graininess, mottle, NPS and banding were surveyed and analyzed with the aid of PIAS™-II personal image analysis software to investigate the stability of normal instrument used in digital prints measurement system. Results show that precision demands are different for various quality parameters and different application backgrounds, namely it is precise enough for common industry detection which has lager tolerance, but higher resolution does good to more effective and more precise measurement especially in R&D.

Novel Algorithm

In this paper, we will introduce a novel low-cost, small size, portable nail printer. The usage of this system is to print any desired pattern on a finger nail in just a few minutes. The detailed pre-processing procedures will be described in this paper. These include image processing to find the correct printing zone, and color management to match the patterns’ color. In each phase, a novel algorithm will be introduced to refine the result. The paper will state the mathematical principles behind each phase, and show the experimental results, which illustrate the algorithms’ capabilities to handle the task.

Inkjet printer motor control consists of moving the printhead in the scan direction and in the process direction. Both movements have different objectives. Scan direction movement needs to have constant velocity and process direction movement needs to have accurate movement. In this paper, we discuss a method for controlling the velocity of the printhead and how to tune the motor control parameters. We also design six test pages for testing accuracy of the printhead movement and cartridge properties. For each test page, we discuss expected prints, common printer control problems that could alter the print quality, and how to identify them.

Tidak adanya nama jalan di lingkungan wilayah tempat tinggal menyebabkan warga RT 04-05 RW 16 Desa Ngenep, Kecamatan Karangploso, Kabupaten Malang kesulitan menemukan alamat tertentu. Kegiatan Pengabdian kepada Masyarakat (PkM) ini bertujuan untuk mendesain, membuat dan memasang Peta Situasi Wilayah di Desa Ngenep, Kecamatan Karangploso, Kabupaten Malang. Kegiatan dilaksanakan di RT 04-05 RW 16 Perumahan Tirtasani cluster Park Royal, mulai tanggal 24 April sampai 09 Nopember 2018. Metode PkM yang digunakan yaitu mendesain, membuat dan memasang Papan Peta Situasi Wilayah.  Rangka Peta Situasi didesain terbuat dari besi profil kotak 4x6 cm dan 3x3 cm berukuran 3x2 m. Pengerjaan rangka meliputi pemotongan, pengelasan, penggerindaan, pengecatan dan riveting. Dasar papan peta dibuat dari bahan lembaran alumnium ukuran 2x2 meter, sedangkan peta yang menggambarkan alamat rumah warga didesain dengan software desain grafis corel draw dan dicetak dengan outdor digital printing. Banner Peta Situasi ditempelkan pada lembaran alumninium dengan perekat lem, dan difinishing dengan rivet. Peta Situasi dipasang didepan pintu masuk RT 04-05 RW 16 (sekitar Pos Satpam) dan Taman Tengah, ditanam dengan kedalaman ± 50 cm dan dicor semen. Hasil PkM menunjukkan bahwa pengadaan Peta Situasi sangat bermanfaat dan warga RT 04-05 RW 16 Desa Ngenep, Kecamatan Karangploso, Kabupaten Malang, dimana warga merasa puas karena memiliki infrastruktur lingkungan yang baik dan lebih mudah untuk menemukan alamat di wilayah tersebut. Kata kata kunci: Desain dan pembuatan, peta situasi, Ngenep.

Background: Color effluents generated from the production industry of dyes and pigments and their use in different applications such as textile, paper, leather tanning, and food industries, are high in color and contaminants that damage the aquatic life. It is estimated that about 105 of various commercial dyes and pigments amounted to 7×105 tons are produced annually worldwide. Ultimately, about 10–15% is wasted into the effluents of the textile industry. Chitin is abundant in nature, and it is a linear biopolymer containing acetamido and hydroxyl groups amenable to render it atmospheric by introducing amino and carboxyl groups, hence able to remove different classes of toxic organic dyes from colored effluents. Methods: Chitin was chemically modified to render it amphoteric via the introduction of carboxyl and amino groups. The amphoteric chitin has been fully characterized by FTIR, TGA-DTG, elemental analysis, SEM, and point of zero charge. Adsorption optimization for both anionic and cationic dyes was made by batch adsorption method, and the conditions obtained were used for studying the kinetics and thermodynamics of adsorption. Results: The results of dye removal proved that the adsorbent was proven effective in removing both anionic and cationic dyes (Acid Red 1 and methylene blue (MB)), at their respective optimum pHs (2 for acid and 8 for cationic dye). The equilibrium isotherm at room temperature fitted the Freundlich model for MB, and the maximum adsorption capacity was 98.2 mg/g using 50 mg/l of MB, whereas the equilibrium isotherm fitted the Freundlich and Langmuir model for AR1 and the maximum adsorption capacity was 128.2 mg/g. Kinetic results indicate that the adsorption is a two-step diffusion process for both dyes as indicated by the values of the initial adsorption factor (Ri) and follows the pseudo-second-order kinetics. Also, thermodynamic calculations suggest that the adsorption of AR1 on the amphoteric chitin is an endothermic process from 294 to 303 K. The result indicated that the mechanism of adsorption is chemisorption via an ion-exchange process. Also, recycling of the adsorbent was easy, and its reuse for dye removal was effective. Conclusion: New amphoteric chitin has been successfully synthesized and characterized. This resin material, which contains amino and carboxyl groups, is novel as such chemical modification of chitin hasn’t been reported. The amphoteric chitin has proven effective in decolorizing aqueous solution from anionic and cationic dyes. The adsorption behavior of amphoteric chitin is believed to follow chemical adsorption with an ion-exchange process. The recycling process for few cycles indicated that the loaded adsorbent could be regenerated by simple treatment and retested for removing anionic and cationic dyes without any loss in the adsorbability. Therefore, the study introduces a new and easy approach for the development of amphoteric adsorbent for application in the removal of different dyes from aqueous solutions.
