Abstract

The effluent discharged from the batik textile industry often contains azo compounds and organic contaminants. One method employed to address these pollutants is the Electrofenton (EF) technique. This study aims to assess the effectiveness of electrofenton in reducing both color content and COD (Chemical Oxygen Demand) in batik dyeing effluent. The Electrofenton process was conducted in batch mode, varying electrode distances at 4 cm and 6 cm, H2O2:FeSO4 molarity ratios of (10:0.05) and (10:0.1), and electric voltage strengths at 6 volts and 8 volts. The research revealed that employing an electric voltage of 8 volts, an electrode distance of 4 cm, a contact time of 120 minutes, and a Fenton dosage molarity of 10:0.05 M resulted in a remarkable removal efficiency of 97.8% with a final concentration of 103 mg/L for color content. Additionally, for COD, employing the same parameters led to a removal effectiveness of 90.1%, with a final concentration of 730 PtCo. The impact of Fenton dosage on COD removal was statistically analyzed using the t-test. The computed t-value of 3.444 surpassed the tabulated t-value of 2.776, indicating a significant influence of Fenton dosage on COD removal.

Abstract

Abstract Production machine maintenance is an activity to maintain the machine's reliability to operate as planned. Apart from reliability, evaluating the effectiveness of the machine is also equally important. Therefore, this research has two main objectives: determining the system's criticality and increasing the effectiveness value of using forklifts using reliability analysis and machine's effectiveness (ME). The research began with collecting operation and maintenance data to calculate the initial conditions of machine reliability and effectiveness. The initial reliability calculation results were 36.79%. Availability is 98.89%, performance is 93.53%, and ME value is 92.49%. The performance value is still below world-class standards, so it needs to be improved. Next, rank the problem using the Pareto diagram for determining system criticality. Efforts to increase performance values to reach world-class standards are carried out by analyzing maintainability and implementing a policy that maintainability values are at least 50% for forklifts and their critical systems. As a result, the availability value increased to 99.74%, the performance value increased to 95.57%, and the ME value increased to 95.32%. So availability, performance, and ME meet the requirements because they exceed world-class standards. Therefore, companies can implement a forklift maintenance policy using maintainability of at least 50% reliability to increase the value of availability, performance, and ME.

Abstract

Jetis Batik Village is a Sidoarjo batik center that produces typical Sidoarjo handwritten batik. The batik processing process produces textile waste which must be processed before being discharged into the environment. Many producers, both large and household scale, have one thing in common, namely producing liquid waste, containing dyes, suspended solids, Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), Total Dissolved Solids (TDS) that need to be managed before being discharged into water bodies. One way of processing that can be done is by using adsorbents. Lapindo mud and Blood Clam shells are abundant natural materials that can be used to process textile waste. Varying adsorbent mass ratios were carried out to determine the optimal adsorbent ratio for processing textile waste. Variations in mass of Blood Clamshells and Lapindo mud (1:0, 0:1, 1:1, 1:2, 2:1). The best variation in reducing COD was variation C (1 g Lapindo mud and 1 g Blood Clam shell) with a removal efficiency of 89.13%. The best variation in reducing TDS is variation E (2 g Lapindo mud and 1 g Blood Clam shell) with an efficiency of 86.07%. The TSS removal efficiency showed relatively the same results 33.33%.

Abstract

This research focuses on integrating lean thinking into a sanitary product manufacturing company, specifically through the identification and elimination of waste. The implementation of the Lean DMAI framework (Define, Measure, Analyze, Improve) is utilized as a continuous improvement strategy to enhance efficiency and reduce waste. Various tools such as Pareto diagrams, root cause analysis, and Failure Mode and Effect Analysis (FMEA) are employed in the stages of defining, measuring, analyzing, and providing improvement recommendations. Results of the study revealed that the waste with the highest Risk Priority Number (RPN) is in the form of defects, particularly in the sub-category of body cracks. The recommended improvement actions include the installation of temperature sensors and misting equipment, along with the application of damp cloths in the lower leg area. These measures aim to slow down the body shrinkage process.

Abstract

Economic growth in Indonesia is increasing rapidly. In Indonesia, the growth of startups is increasing along with the continued development of the digital industry. The emergence of startups in Indonesia began in 2010 which was pioneered by the presence of startups Tokopedia and Blanja.com. PT. XYZ as a state-owned enterprise supports the development of startups by providing digital creative facilities, funding, and expanding market access, specifically to accelerate their industrial growth. The amount of funding that PT XYZ will provide to startups also varies according to the startup development stage and the company value (valuation) of the startup. The valuation calculation that is currently being carried out by PT. XYZ is by using the First Chicago method as the calculation method. However, in its application, there are still several calculation components that have not been standardized. The absence of standards for some of the components of this calculation can affect the size of the calculated startup valuation figures. This will have an indirect impact on startups, investors and stakeholders. Therefore, this study aims to analyze the standard setting on the three components of valuation calculations or business appraisals at startups carried out by PT. XYZ and to establish improvement evaluation standards for determining the three components of calculations in the first Chicago method. In this study, the results of the startup assessment are the dependent variable while the annual average growth rate, stock value size and discount rate are the independent variables. The sample population used in this study were startups who became alumni of PT. XYZ. The analytical method used is using linear regression.

Abstract

PT. Betts Indonesia is a manufacturing company that produces laminate tubes. In the production process, several materials used in the production process to become finished products. The problems found in this study are the irregularity of the layout of production materials, often the placement of materials that are not in accordance with the material specifiedFor the flow of raw materials, bottlenecks often occur because the existing lines are narrow, so they have to alternate with each other, which causes a decrease in the efficiency of the production process. The method in this study uses the Activity Realition chartto improve the material flow that has been carried out currently with the aim of rearranging the layout of efficient production facilities so as to optimize material handling. From the results of this study it is expected to rearrange the flow of raw materials more efficiently so that the level of the production process can produce the maximum production process from the targets set by the company.
