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.
