Abstract

The automotive industry is known to increase exports since 2015 and is predicted to continue to grow. To develop the industry, the government is known to issue several schemes, and one of them is in the form of mandatory rules for partnerships with the small and medium industrial sectors. However, there is no industrial, institutional map seen from various aspects, including technology, human resources, information, and organization. This map is essential and useful for stakeholders to develop the industry because it provides more directed assistance.In this study, the small and medium industries for processing metal automotive components in Tegal City are used as mapping objects. The technometric method is used to calculate the level of technology contribution they have. The results of this study indicate that the four aspects covering Technoware, Humanware, Infoware, and Orgaware for small and medium-sized automotive component processing industries in Tegal City are in a reasonable range. For improvement or guidance, production facility technology is the priority. Then proceed to employee competencies, information systems, and organizational management. Mapping should be done regularly every five years or less than five years as an evaluation.

Abstract

This research was conducted to determine the conditions and manipulate the acoustic material by the mathematical experiment method the calculations was using a specific formula replacing the value of material acoustic sound coefficient. The focus of this research was analyzing the sound absorption and noise reductions of acoustic materials used in residential arround Adisutjipto airport of Yogyakarta then proceed with the analysis of sound absorption and noise reduction of coconut palm fiber designed acoustic materials based on buiding physical theory.The results show that the low sound absorption and noise reduction of the acoustic material inside the sample chamber was due to the material used had a sound reflector characteristic, so optimize the noise reduction it was needed an additional layer of acoustic material used in the fields. The high sound absorption and noise reduction of the coconut palm fiber desgned materials caused by these materials had sound-absorbing properties. The addition of coconut palm fiber layer for acoustic material could optimize the noise reduction. In addition, the coconut palm fiber acoustic material could be used as an altenative sound dampening material at high frequencies that could potentially reduce the waste of nature. Keywords : Residential, accustics materials, coconut fiber, mathematical experiment.

Abstract

ABSTRACT South Processing Unit (SPU) is a gas field that produces condensate and natural gas. The process of producing condensate and natural gas might have an impact to the environment. Life Cycle Assessment (LCA) is a method which measure the environmental impact related to a product of natural gas and condensate processing. This method can be used to evaluate and analyze environmental impacts. This study aims to find out which process units that have a major impact to global warming and human toxicity then provide recommendations for improvements in order to reduce environmental impacts. LCA method and Software SimaPro version developer 9.0 are used during this study. Based on the results, shown the environmental impacts occurred in the process unit for processing gas and condensate product in SPU field. The process units are LP Compressors, Turbo Electric Generator, SCP Flare, SMP Flare, and Sodium Hydroxide Injection. The LP compressors are the biggest contributor for global warming and human toxicity with the impact of 2.855,236 kg CO2 and 8,884 kg 1.4-DB eq. The recommendations to reduce environmental impacts are using biomass as an alternative fuel, adsorption of CO2 with a zeolite adsorbent, and planting of CO2 absorbing plants.

Abstract

This research is part of an effort to solve waste management issues in Sleman Regency, focusing on measuring and evaluating the Zero Waste Index (ZWI) in the Green Open Space (RTH) Denggung, Sleman. The resource substitution method was used to assess the efficiency and potential for waste reduction in the area. Based on field data and calculations using the ZWI formula, it was found that the ZWI value in RTH Denggung is very low, only 0.14, meaning that only about 14% of resources are recovered from the waste management system. This indicates that waste management in the area is not yet optimal, necessitating improvement and innovation efforts. The proposed strategies include enhancing the recycling of plastic, paper, and styrofoam waste, as well as developing composting for food scraps and other organic waste. The implementation of stricter policies related to waste management, public awareness campaigns, and the integration of zero waste initiatives are expected to improve the ZWI value. This effort is hoped to be part of the solution to waste management in Indonesia and serve as a best practice example for waste management in RTH or other public spaces..
