Abstract

Urban drainage is a network system for waste disposal in urban areas that functions to manage or control surface water, so that it does not disrupt or harm the community and provides benefits for human activities. This research aims to create synergy and steps for the implementation of eco-drainage in the urban characteristic conditions of Karawang Regency. The method used involves data collection through observation, interviews, historical data analysis, and mapping based on SNI Number 02-2406-1991 regarding the General Planning Procedures for Urban Drainage. The research results indicate that the Eco drain infrastructure consists of 7 elements, namely rainwater harvesting, infiltration wells, retention ponds, trash filters, bioremediation, biofilters, and water quality treatment using constructed wetlands. Meanwhile, the local government of Karawang Regency does not yet have the infrastructure to implement eco-drainage. After conducting an analysis, it was determined that among the 7 elements of eco-drainage, rainwater harvesting is the most needed to address the issues of flooding and drought in the Karawang area. The research results also include calculations and explanations regarding the Eco drain facilities for rainwater collection on a land scale and environmental/community storage tanks, as well as the quality of rainwater in Indonesia.

Abstract

Kandayas Furniture is one of the companies engaged in manufacturing tables. The table production process goes through several stages. Based on field observations and interviews that have been conducted, problems arise from the company's production process. The problem exists in the assembly process because many products are waiting, so there is a buildup in the assembly process of the table. The buildup occurs because the assembly process to the finished material warehouse has a considerable distance difference. This resulted in an ineffective production process. Then, in Promodel Now the movement of each work station still uses human labor which results in delays in the production process. From this problem, it is obtained that the process flow changes are more structured, the material handling distance from assembly to finished goods is shorter because there are changes in the lay out that we propose and make material handling time more efficient, using handlift conveyance in each flow, adding assembly operators due to bottlenecks in assembly due to the paint drying process, using a paint oven machine for drying paint to shorten the time and reduce the accumulation of goods, and implementing K3 according to the SOP so that employees avoid work accidents.

Abstract

Abstract. Waste volume in Karawang City that can be handled will only be 40% and the other 60% will be managed by waste banks and temporary shelter. Innovation in waste recycling is needed, one of which is making plastic waste as raw material for paving block production. This research aims to assess how using plastic waste as a material in making paving blocks affects their compressive strength and water absorption, with the potential to reduce overall plastic waste and explore alternatives to conventional materials. This research focuses on testing water absorption capacity and compressive strength based on SNI 03–0691–1996 standards for making paving blocks. The water absorption test results on PVG 1 and 2 are up to 38.46% larger than PVG 3 and 4 because there are many cavities in PVG 1 and 2 that making were below standard, and PVG 3 and 4 were at quality standard level B. The compressive quality test of PVG 1 and 2 have a more noticeable compressive quality regard with a typical regard of 6,075 MPa compared to clearing squares with a full plastic composition with an ordinary regard of 4,745 MPa. It happens since of insufficient and manual burning, but it can too be caused by an ought to utilize plastic waste and the got to age the clearing squares being attempted. When compared with the quality Indonesian National Standard (SNI 03 - 0691 – 1996), the compressive quality test of the clearing inside the examination did not meet the standard.Keywords: Plastic Waste, Paving Block, Water Absorption Test, Compressive Strength

Abstract

Domestic wastewater discharge remains a major factor contributing to the deterioration of river water quality, as untreated effluents are still commonly released directly into river systems. This concern is particularly evident in the downstream segment of the Kusan River tributary, situated in the villages of Sungai Lembu and Beringin. The intensifying expansion of residential settlements in the area has been identified as a key driver of pollution in the Kusan River, with its scale increasing annually. Environmental degradation arises when the pollutant load exceeds the assimilative capacity of the aquatic ecosystem. Under such conditions, the natural recovery process becomes protracted and increasingly ineffective, resulting in persistent contamination. This research is designed to assess the influence of surrounding anthropogenic activities on the water pollution index and the ecological condition of the Kusan River tributary in the aforementioned villages, within Tanah Bumbu Regency, South Kalimantan Province, employing the Water Pollution Index (WPI) methodology. Based on laboratory analyses, Total Suspended Solids (TSS) concentrations in the lower reaches of the tributary exceed 50 mg/L, thus surpassing the threshold set by Government Regulation No. 22 of 2021 concerning Water Quality Management and Pollution Control. Moreover, findings from the pollution index evaluation indicate that water quality in the study area ranges from good to lightly polluted, with index scores varying between 0.33 and 1.73.
