Abstract

Marble, one of natural stone, has been widely produced since the last decade. In South Aceh, Marble stone is fabricated at Marble Production Unit that is located around Polytechnic of Aceh Selatan. The using of large-scale stone-cutting machines in Marble Production process tends to be a major noise source in Polytechnic of Aceh Selatan environment. The aim of this study is to analyze the noise level generated by Marble Cutting Machine in Marble Production Unit. The noise levels were analyzed by measuring Background Noise Level (BNL) and Sound Pressure Level (SPL). Sound Level Meter Type SL-814 was employed in the measurement. The results show that Background Noise Level measured is 53.03 dB on average. The highest Sound Pressure Level measured when the marble cutting machine was operated without workpiece is 94dB. In addition, the highest sound pressure level measured when marble cutting machine was operated with the workpiece is 96 dB. The values have generally exceeded the Threshold Noise Level allowed for education area, 55 dB. The noisy condition in campus environment would have an impact on teaching and learning processes within the Polytechnic of South Aceh.

Abstract

  ABSTRACT The enclosure of the Krueng Matee waters by vegetation can threaten the preservation of underwater biota, such as fish and shrimp due to lack of oxygen and sunlight, thus the water hyacinth plants reproduce as weeds in the waters of the Krueng Matee river, Kuala Ba'U Village and affect the livelihoods of Kuala Ba'U fishermen. One of the efforts that can be made to overcome water hyacinth weeds is to utilize water hyacinth plants for compost. This community service activity aimed to provide skills in processing water hyacinth into compost for the people of Kuala Ba'U Village. The stages in implementing this activity consisted of field observations, carrying out village administration, the Participatory Action Research (PAR) method, preparation of materials and a multipurpose counter machine. The result of this community service was the availability of compost from water hyacinth as well as a good response and welcome from the community and community leaders of Kuala Ba'U Village because the community gained knowledge and skills in processing water hyacinth into compost, thereby reducing water pollution and improving the community's economy, especially for farmers. In addition, this activity can also normalize the estuary of the Krueng Matee river from water hyacinth weeds, so fishermen can return to fishing and catching fish.
