Abstract

Domestic liquid waste typically originates from home trash and requires treatment to decrease quantities of Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solid (TSS), and mixed particles. Additionally, treatment is necessary to eliminate nutrients and harmful components. The objective of this study is to determine the optimal dosage of biocoagulant needed for the process of coagulation and flocculation in a laboratory setting using the jar test method, specifically for treating domestic wastewater. Tamarind seed shell waste contains tannin, which can act as a natural coagulant. It functions as a positively charged natural polyelectrolyte that efficiently binds to negatively charged colloidal particles. The study included independent variables consisting of different doses of a mixture between tamarind seed shell and sweet orange peel bio coagulants, with ratios of 1:0, 1:0.5, and 1:1. An optimal dosage of 1.5 grams of tamarind seed shell effectively reduced turbidity by 51%, BOD levels by 80%, and COD levels by 77%.

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.
