Abstract

Mangrove bark and coconut fiber can be used as natural dyes, because they contain tannin compounds, which are a natural brown color. The aim of this research was to determine the effect of soaking time for coconut fiber in mangrove bark extract on the color intensity and color fastness of washing soap on cotton fabric as well as the effect of lime fixator on soaking coconut fiber and mangrove bark extract. The process of extracting mangrove bark uses a water solvent, a ratio of raw materials to solvent of 1:10. The soaking process is within 24 hours and 48 hours. The fixation process is carried out by immersion technique. Color intensity test using a UV-2401 PC spectrophotometer and color fastness to soap washing using a gray scale standard. The research results showed that the smallest R% value or the lowest color intensity which produced the darkest color was the treatment of soaking coconut fiber in mangrove bark extract for 48 hours with or without a fixator. The lime fixator treatment shows a greater R% value, meaning that the lime fixator treatment produces a higher intensity or lighter color. The best color fastness after soaking coconut fiber for 48 hours with a score of 4-5 in the good category. Lime fixator can maintain the color fastness value of dyes that have absorbed into the fabric.

Abstract

The different behaviour of soils from one region to another requires in-depth identification of the reaction of soils to certain treatments. A comprehensive study is needed to obtain information on the cause and effect of geotechnical cases such as collapse and landslide. The analysis conducted in this paper is based on the collapse of the Gunung Ulin - Gunung Sari road section that occurred in 2018 until the emergence of potential landslides on the excavated slope in 2021 for the construction of retaining walls. The analysis was carried out by reviewing the location of the collapse and conducting identification in the form of field and laboratory soil tests. The information obtained was then used to analyse the stability of the slope under review with the Geo5 application. The results of the analysis based on the geotechnical approach assumed that the collapse was caused by the condition of the soil layer itself in the form of soft clay and claystone whose condition was influenced by high rainfall during the time span of the incident. The analysis results obtained in this paper are expected to be a reference in anticipating similar events to occur in the future.

Abstract

Clean water and sanitation are two things that cannot be separated users of drinking water or clean water will definitely produce waste water, no less than 85% of clean water turns into waste water. Indonesia has a percentage of adequate sanitation services at 74.58%, including 7.42% for safe sanitation. These figures are accompanied by a high percentage of open defecation practices, approximately 9.36%, equivalent to 25 million people, which places Indonesia as the third highest in the world for open defecation rates. Households that have access to sanitation are those connected to the Wastewater Treatment System (SPAL), which is pumped and disposed of at the Fecal Sludge Treatment Plant (IPLT). 272 IPLTs built in 2018, only 8 are operating optimally. Local governments establish a regional entity as a service provider (operator), which can take the form of UPTD, BLUD, and BUMD. This research aims to identify performance indicators for each institution, identify regional potential for each institution, recommend strategies and analyze the business model of each institution. The analysis used in the research was to obtain regional potential using the interview method. Data analysis using the ATLAS.Ti application was then analyzed narratively. The results are useful for knowing strategic recommendations for Waste Water Treatment Systems (SPAL) and business development for each institution.

Abstract

Water pollution is a serious environmental problem caused by human activities, especially in urban areas. The Rejo Agung River in Jombang District, East Java, was the focus of the study due to the impact of pollution from household waste and the tofu industry. In order to control water pollution, QUAL2Kw modeling was used as a tool to identify major pollution sources, predict changes in water quality, and test the effectiveness of countermeasure strategies. The study revealed that the water quality of the Rejo Agung River, although still meeting quality standards, experienced a significant decline in the Dissolved Oxygen (DO) parameter at several sampling points, indicating a pollution problem that needs to be addressed. The modeling results show that the river has varying pollutant load carrying capacity, with water quality degradation mainly in DO levels. The STORET method analysis also showed that the level of pollution varied from mild to moderate pollution. Various pollution mitigation strategies were proposed, including socialization to the community on waste management, monitoring of industrial and household waste discharges, river clean-up activities, improved management of communal WWTPs, as well as technical studies for water class determination and pollution load carrying capacity as the basis for granting permits. With the implementation of appropriate strategies, it is expected that water pollution in Rejo Agung River can be reduced, maintaining the sustainability of the river ecosystem, and improving the quality of life of people who depend on these water resources.

Abstract

Waste, if not managed properly, has the potential to reduce environmental quality. Kahayan River Watershed (DAS) it was concluded that the heavy metal content of Lead (Pb) was the highest. In Central Kalimantan, the water hyacinth plant (Eichornia crassipes) is a plant whose growth rate can threaten fish populations in rivers. The use of Water Hyacinth (Eichornia crassipes) is expected to reduce levels of the heavy metal pollutant Pb (Lead) in the water. The research method used is quantitative research. The test results showed that the Pb (Lead) concentration before treatment was significantly different from the concentration after treatment, this shows that the plants had a real effect in reducing the concentration of the heavy metal Pb in water. Based on the results of observations, it can be shown that there were morphological changes in the water hyacinth plants (Eichornia crassipes) from the beginning of the study until the 4th day. Water hyacinth (Eichonia crassipes) has been proven to reduce the heavy metal Pb (Lead) in the biotreatment of water polluted by the heavy metal Pb (Lead). Water hyacinth (Eichonia crassipes) reduces the heavy metal Pb (Lead) through the process of absorbing water by the roots, so that Pb (Lead) in the water is also absorbed. Then it is absorbed into the stem and spreads to the leaves of the Water Hyacinth plant (Eichornia crassipes).

Abstract

Solar Power Plant is a new renewable energy source that can be utilized and is very accessible because it uses sunlight as the main medium of generation. Sunlight is expected to shine on the solar panel with a breakthrough using an aluminum foil reflector. Aluminum foil that provides reflection of sunlight can increase the output efficiency of solar panels. To get the productivity of electricity generated by the panel, maximum sunlight is needed on the surface. Reflectors can increase the intensity of sunlight with less heat generated. By using aluminum foil, the sunlight will be directed to the solar panel thus increasing the output power produced. The angle and tilt of the reflector will be adjusted to the position of the solar panel. The reflection of the aluminum foil has an effect on the intensity of light received by the solar panel and an increase in output power of 2-5%.

Abstract

Heavy metals analysis on cassava around ex Leuwi Gajah Landfill aimed to determine the effects of waste and leachate that contain heavy metals on plants nearby. The analysis was conducted from soil and cassava roots samples. The heavy metals compounds that were determined are Fe, Pb, Cd, Cu, and Zn.Sample destruction was conducted by ash method and then analyzed by Atomic Absorption Spectrophotometry with curve calibration method. We also conducted the water content, ash content, and silica content from the sample by gravimetric method. The analysis results were compared with the control variable by the student t-test method. There is no Cd detected on all cassava samples analysis. On the other hand, Pb concentration detected was exceeded the Indonesia National Standard (SNI) and Foodand Agriculture Organization / World Health Organization (FAO/WHO) permissible limits about heavy metals compounds on food and plants. The student t-test result shows that there is a significant difference in heavy metals content between cassava in landfill and cassava control variables.
