Abstract

This study discusses the implementation of redox reactions on the thickness test of the galvanized (zinc-coated) layer using the JIS-H-0401 standard to help Small and Medium Enterprises (SMEs) industries. Some of the finished products go through the galvanizing process in the metal processing industry. Quality constraints, especially related to the thickness of the galvanic (zinc-coated) layer, have become an object that is less controlled because of the limitations of the test equipment used. This research uses an experimental method applied to one of its products: a flat washer with SPCC material and a thickness of about 2.20 mm. SPCC - SD material is classified as low carbon steel based on its carbon content. 5-unit flat washers were identified with sample codes A, B, C, D, and E. Flat washers have an internal diameter of 22.65 - 22.7 mm. In comparison, the outer diameter is between 43.75 - 43.80. The redox reaction process uses HCl (hydrochloric acid) with a concentration of 1 M, which is diluted with water (H2O). The zinc thickness test results show that the flat washer has an average thickness of 10.52 microns with a minimum and maximum thickness variation of 10.66 -10.72 microns.

Abstract

Pesantren At Taubah, sebagai pondok pesantren modern, mempunyai visi “menjadi Lembaga Pendidikan Islam berbasis life skill unuk menyiapkan generasi Indonesia yang maju, berkarakter/adab, dan memiliki keterbukaan wawasan iptek yang bermanfaat bagi lingkungan”. Pengabdian kepada masyarakat telah dilakuakn dengan tujuan untuk penambahan pengetahuan para santri di pondok pesantren tersebut tentang energi terbarukan, khususnya panel surya, merupakan salah satu upaya dalam menggapai visi pesantren, dimana mereka akan mempunyai ilmu dan pengetahuan (iptek) terkini. para santri juga memahami bahwa sumber energi surya (matahari) mempunyai dampak yang lebih baik bagi lingkungan dibandingkan dengan energi yang bersumber dari fosil. Pengetahuan tentang manfaat sumber energi surya telah mampu dibarengi dengan keterampilan para santri tentang bagaimana cara untuk merangkai peralatan panel surya hingga dapat dimanfaatkan menjadi sumber energi listrik. Para santri juga telah diberi pengetahuan dan keterampilan merangkai panel surya yang diiringi dengan pengetahuan penghitungan daya, tegangan, dan arus yang dihasilkan dari rangkaian panel surya yang direncakan atau yang telah dibuat.

Abstract

XYZ is a company engaged in the paper industry, which is located in West Java. Since established in 1976, this company has produced photocopy paper in the form of reams. This company has advantages in terms of paper quality so that its products dominate the international market and the domestic market. With a very tight level of market competition, companies must continue to work optimally to continuously improve employee performance and company productivity. The purpose of this study is to plan an incentive-based employee wage system, which is suitable and in accordance with company conditions. Incentive wages are important as one of the main components to increase and maintain motivation, performance and work integrity. This research was conducted in the Finishing Department of the copy manual wrapping work unit. The method used are the Piecework method, the Halsey method, and the Rowan method. The result of this research is a comparison of the amount of wages between the wage system used by the company and the three methods of incentive pay as a company alternative. From the comparison of the three incentive wage design methods, the authors recommend the Halsey method as the best method that is able to provide benefits for both the company and for workers which we call dual mutualism. The Halsey method still guarantees a basic wage and a decent incentive wage for workers as a motivation to work faster and better.
