Abstract

Global warming is an ecosystem imbalance caused by an increase in atmospheric temperature mainly caused by the Greenhouse Gas effect. Global warming potential (GWP) is caused by several human activities, one of which is waste management. This study aims to analyze the environmental impact, especially on the amount of GWP in the waste transportation system in Panakkukang sub-district, Makassar using the Life Cycle Assessment method of Simapro software version 9.5. The research stages by analyzing the transportation route that has been applied and then comparing it with the scenario route as an alternative route on the type of arm roll truck vehicle. The research shows in general that the existing route is the shortest transportation route with the smallest GWP impact. The amount of GWP for the entire waste transportation route in the Panakkukang sub-district, Makassar is 1,352, 64 kg CO2 eq.

Abstract

SMK Negeri 2 Manokwari West Papua Province is one of the vocational high schools that foster 12 competencies in the field of Technology and Engineering with 1,567 people active in 2022. To support daily activities at school, the availability of clean water in the school environment is necessary for washing hands, defecating, and urinating. The availability of clean water is at least balanced with the need for clean water, this is intended to ensure that school needs are fulfilled. This study aims to analyze the need for clean water and clean water quality by quality standards. Clean water needs are analyzed using a mathematical approach based on clean water planning criteria, while the clean water quality analysis is carried out by testing clean water samples through the Manokwari City BPOM laboratory. The results showed that the need for clean water in schools was 17,280 liters/day. Water distribution to bathrooms/toilets, sinks, and public face, uses a piping network sourced from 2 reservoirs with a capacity of 40,400 liters. The source of raw water used is groundwater and pumping systems. For the analysis of clean water quality, the data shows that the temperature parameter = 0.05 oC, pH = 7.88, TDS = 0.3060 mg/L, and coliform number = 27.09 x 10^1 CFU/100 mL, so that the water quality microbiologically does not meet the requirements for sanitary hygiene. While the results of the study showed that the need for clean water in SMK Negeri 2 Manokwari until 2032 reached 33,276 L/day (47.21%). The results of this study are expected to be useful for the development of science for academics in universities, government and society. E, especially for students at SMK Negeri 2 Manokwari, hopefully, it will be interesting reading material in the school library.

Abstract

The research location is located in Tanggetada sub-district, Kolaka district, which is an area very close to laterite nickel mining sites. The determination of the research location was deliberately chosen at the nickel mining location, with the consideration that at that location the river was brownish red, and at that location there were many miners who did not carry out according to mining regulations. The method used is observational which is carried out at nickel laterite mining sites. by using a cross sectional approach that is both qualitative and quantitative. Based on the results of the data analysis that has been carried out, it can be explained that the distribution of heavy metal pollution in river water is the largest in the heavy metal Copper (Cu), namely 0.0108 mg/l, which is found at station 3, heavy metal lead (Pb), namely 0.0070 mg/l l found at station 4, heavy metal chromium (Cr) is 0.0038 found at station 6 downstream, heavy metal Cadmium (Cd) is 0.0028 mg/l found at station 3, heavy metal Hexavalent Chromium (Cr6+) is 0.0026 mg/l found at station 2. From the results of the analysis there are no heavy metals that exceed the quality standard (PP No. 82 of 2001). Meanwhile, the river sediment material produced the greatest amount of heavy metal Copper (Cu), namely 0.0229 mg/kg found at station 2, Heavy metal Cadmium (Cd), namely 0.0128 mg/kg found at station 5, Heavy metal Lead (Pb) namely 0.0177 mg /kg is found at station 1 upstream, heavy metal Chromium (Cr) is 0.0118 mg/kg found at station 6 downstream, heavy metal Hexavalent Chromium (Cr6+) is 0.0116 mg/kg found at station 6 downstream. From the results of this analysis there are no heavy metals that exceed the quality standards (USEPA, 2003).

Abstract

The vulnerability of landslides that occur in the Sakuli area, Kolaka Regency is related to topographic conditions which are dominated by mountains and hills, for this reason, research is needed as an effort to determine the level of vulnerability and determine disaster mitigation efforts against the danger of landslides. This type of research is quantitative descriptive by looking at the influence of each variable to analyze landslide-prone areas. The method used in this research is experimental analysis with direct observation in the field. From the research results, the vulnerability level value for the slope parameter was 0.83; with soil texture 0.408; for faults 0.86; value for regolith 0.363; with geological conditions 0.628; with a rainfall value of 0.3 and land use of 0.6, the accumulated value is that the research area is at a very vulnerable level with a value of 3.989. Therefore, this area really needs structural and non-structural mitigation to be able to protect and reduce the potential for landslides.

Abstract

The handling of human hair waste is still not optimal, as it is often discarded or burned, leading to environmental pollution. This research aims to utilize human hair waste as a mixture in normal concrete, resulting in a fiber-reinforced concrete product with marketable value, providing a more beneficial use compared to simply being disposed of or burned. The purpose of this study is to analyze the mechanical properties of concrete using human hair fibers. The mechanical properties to be analyzed include compressive strength, tensile splitting strength, and flexural strength. This research is based on laboratory experiments. The variations in the amount of fiber used in the study are 0.25%, 0.5%, 1%, and 1.5% of the cement weight in the concrete mix. Based on the results of mechanical property testing, it can be concluded that the optimal addition of 1% human hair fibers yielded a compressive strength of 22.86 MPa, tensile splitting strength of 2.69 MPa, and flexural strength of 4.13 MPa.
