The purpose of this study is to measure legal protection and employment opportunities for persons with disabilities who work in various companies in the city of Semarang, Central Java. As is known, the right to work for citizens is regulated in Article 27 Paragraph 2 of the 1945 Constitution, which mandates the right of citizens to get a decent job and life. Every citizen has the same rights and the state (government) has regulated these rights in terms of obtaining employment without exception, including persons with disabilities. This study uses a juridical-empirical (non-doctrinal) approach, which examines how employment opportunities and legal protection of persons with disabilities in the city of Semarang, especially in PT. Samwon Clothing Indonesia. Primary data sources were obtained from PT. Samwon Busana Indonesia through interviews, secondary data in the form of legal material. Data Collection Method with Interview and Documentation methods, Data Analysis is done by a descriptive method. The results showed that employment opportunities for workers with disabilities in the city of Semarang, especially in PT Samwon Busana Indonesia had fulfilled one percent of the total employees. The total disability workers at the company are 14 out of a total of 1317 employees. In terms of legal protection, all employees both with disabilities and do not get the same rights and opportunities to be treated fairly. In addition, fulfillment of the rights of workers with disabilities is also fulfilled without discrimination.

One of the problems the aircraft industry faces is equipment that has decreased performance in the period before planning. The solution to this condition is that a material that has hard properties and is corrosion-resistant is needed. Aluminium is a metal that is applied as equipment in the industry because it has the characteristics of being light, strong, corrosion resistant and easy to shape, but has properties that are easy to deform, have low hardness and wear resistance. Anodizing process has the characteristics to improve the surface properties of aluminium metal in physical and mechanical properties. The anodizing process of aluminium metal using sulfuric acid solution produces a thicker oxide layer than in other solutions, such as phosphoric acid solution. This research studied the effect of phosphoric acid concentration on process efficiency, oxide layer thickness, and the hardness of the anodized oxide layer in 16% sulfuric acid solution. Phosphoric acid solution concentration varied from 0; 0.5; 1;2;4; and 8% in 16% sulfuric acid solution at 5 Volts voltage or 1.12 A/dm2 current density with 25 minutes processing time. The results showed that the anodizing process in 16% sulfuric acid solution had the lowest efficiency of 19.3% after adding variations in the concentration of phosphoric acid. These conditions reached the optimum in 16% sulfuric acid solution with the addition of 1% phosphoric acid; 26.6 mg oxide mass; 50.33% efficiency; 90.48 mg/dm2 oxide layer thickness and 86.57 HV metal surface hardness

Papaya leaf extract could be used as an organic corrosion inhibitor. Corrosion inhibitors were used as a method to reduce corrosion rate. The most corrosive environment was the marine environment. The purpose of this study was to determine the best concentration of papaya (Carica papaya) leaf extract inhibitor which could reduce the corrosion rate of low carbon steel in a 3.56% NaCl solution environment. The maceration process was carried out for 24 hours with 70% ethanol solvent with a solute:solvent ratio of 1:8 (w/v) at room temperature. Inhibitor extracts were analyzed qualitatively with the phytochemical method. The addition of FeCl3 was carried out on the inhibitor extract from papaya leaves. The color change occurred from blackish brown to greenish black which indicated the presence of tannin compounds in the papaya leaf extract. Corrosion testing was carried out with hot stream temperature setting at 45â°C to 55â°C and concentrations of inhibitor extracts at 300, 600, and 900 ppm. The test was conducted for 36 hours with a span of metal mass every 6 hours. Corrosion rate calculation is done by weight loss method. The results showed that papaya leaf extract inhibitors positive contained corrosion inhibitor and could reduce the corrosion rate in 3.56% NaCl solution. The corrosion rate without inhibitor is 1.023 mmpy. Corrosion rates with inhibitor concentrations of 300, 600, and 900 ppm were 0.755, 0.585, and 0.438 mmpy, respectively.
