Abstract

E-waste is all objects included in a wide variety of electronic devices and their developments ranging from large household electronic equipment such as refrigerators, air conditioners, cell phones, stereo systems, and other consumptive electronic devices, to computers that are discarded by their owners. This study aims to determine the potential amount of used electronic goods (E-Waste), the amount of electronic waste generation, electronic waste management and the potential value of electronic waste recycling generated by the community which if not managed will cause a negative impact on the environment and public health of Pamengkang Village, Kramatwatu District. The type of research used is descriptive and qualitative research with research techniques using surveys. This research uses literature and field research such as interviews, observations and questionnaires. with a sample of 32 respondents, the sampling technique using quota sampling. research data processing was carried out using SPSS tools. Data were analyzed using univariate analysis. The results of the univariate analysis showed that the most electronic waste generated by the community was a TV as many as 7 (21.9%) and a fan as many as 7 (21.9%) and for the management of electronic waste the most done by respondents, namely electronic waste management by storing 23 (71.9%). As for the highest recycling value of electronic waste in Pamengkang Village, namely electronic materials at a price of Rp. 30,000, -.

Abstract

The focus of this study is the issue of reorganizing the preexisting Islamic Geometric Patterns found at the Cheng Ho Mosque via the use of computer modeling techniques. The need for computer modeling research for rearranging geometric patterns at the Cheng Ho Mosque may be attributed to many factors. The objective is to use digitization to streamline the ornamental design process. The study methodology used included the analysis of geometric forms, which were then processed and patterned using Parametric Islamic Geometric Patterns with the assistance of Grasshopper software. This study employs the Islamic octagonal archetype, similar to Chinese geometric ornamentation, using circular geometry with a radius input, as discussed in the preceding article. The inclusion of the division shape serves as a necessary limitation to facilitate the cutting of the recurring patterns. The findings indicate that the algorithmic technique is constructed using a collection of parameter inputs organized into four primary components: octagonal basis geometry, repetition procedure, partition or boundary-shaped surface, and material dimension simulation. However, it also demonstrates varying parameter inputs, posing challenges in organizing them accurately to generate the octagonal form. Visual scripts may effectively depict Islamic geometry in open systems that exhibit parametric adaptability to the fundamental principles of division. During the design processing phase, it is possible to exert control over the pattern proportions in some instances.

Abstract

Every company, both private companies and individuals, certainly has the goal of getting the maximum possible profit from the business concerned and completing work according to a predetermined schedule. elements that are no less important than the success of a delivery of raw materials, and what is more important is to create a sense of satisfaction for the customer either quality, cost or time. The method used in this study is the CPM method. CPM is a network analysis that seeks to optimize the total project cost by reducing the total project completion time concerned. Microsoft Projects is designed to assist project managers in developing plans, assigning resources to tasks, tracking progress, managing budgets and analyzing workloads. The results of project calculations at the initial conditions with 65 working days normally without using overtime the company spent Rp. 108,623,550, - whereas after accelerating the fabrication time for 3 days from 65 days to 62 days the company spent more project costs of Rp. 127,691,810, -. Based on the results of the crashing this program, the company can anticipate project delays and for achieve a change in project completion time of 62 days and avoid a penalty penalty of 20% of the project value and the company can work on other project work.

Abstract

- In an era of changing consumer needs and high demand for reliable products, companies need to improve product quality to be able to maintain their business in a competitive industrial world. Including the quality of the boiler as a component of the thermal power plant must be maintained at good performance so that the power plant can operate normally. This study aims to improve the quality of boiler fabrication through the application of the FMEA method. The results showed that the average percentage of weld defects from the results of radiographic testing exceeded the target set by the company for tube-tube, header-header and header-end caps welding joints. Types of welding defects that often occur are porosity welding defects with a percentage of 36%. Based on the data analysis, there are four main factors that influence the welding results, including the ability of the welder, the conditioning of the welding electrode, the parameters of the welding machine, and environmental conditions. Methods: This study aims to determine the factors that cause welding defects in the boiler fabrication process in a power plant component company. The type and design of the research carried out is quantitative research with case studies. From the results of data processing regarding the defect rate, the research focused on the results of radiographic testing that exceeded the company's target. The result was that the type of defect with the highest percentage was porosity of 35.8% or around 36%. That is, most of the welding defects that cause failure in the welding results are the occurrence of weld porosity. Meanwhile, for other types of welding defects, the percentage is below 30%. Based on the results of data collection and analysis, it can be concluded as follows: the dominant type of weld defect in boiler fabrication from radiographic test results is porosity weld defect, the main causes of porosity welding defects include the ability of the welder, not conditioning the electrode/welding wire, welding machine parameters, and environmental conditioning. Quality improvements include, among others, the welder by holding training and testing the WPQ (Welding Performance Qualification) again for each project, performing treatment on the welding wire, supervising the setting of the welding machine parameters, and covering the welding area with cloth or tarpaulin so that the welding area is free from wind. and other environmental conditioning.
