Abstract

Liquid waste from the tofu industry contains various organic and inorganic substances which can reduce water quality. This research aims to assess the effectiveness of Poly Aluminum Chloride (PAC) as a coagulant in reducing pollution parameters in liquid waste from the tofu industry. In this study, experiments were carried out with three variations of PAC doses (75 mg/L, 150 mg/L, and 225 mg/L) and different stirring times (10, 15, and 20 minutes) using the jar test method. The jar test method is a standard laboratory technique used to determine the optimal dose of coagulant needed to remove turbidity from wastewater. The results show that a PAC dose of 225 mg/L with a stirring time of 20 minutes is the optimal condition, reducing Total Dissolved Solids (TDS) from 996 ppm to significantly lower. The initial conductivity of 1971 µs decreased after the addition of high doses of PAC and longer stirring times. The pH parameter increased from 4 to 5. Although still acidic, this increase indicates a reduction in acidity, which can be useful in reducing negative impacts on the aquatic environment. The color of the wastewater becomes clearer and the odor decreases, indicating a decrease in organic compounds and dissolved substances. The temperature remained stable at 28ºC before and after treatment. This research confirms that PAC is effective in improving the quality of wastewater from the tofu industry through the coagulation mechanism, producing cleaner and clearer water with a significant reduction.

Abstract

The aim of this research is to analyze the structure of plankton abundance and water quality in the Batang Hari River in Tebo Regency. The research method used was purposive sampling at 3 (three) points on the Batang Hari River during February - July 2024. The research results found 3 classes of Phytoplankton, namely: Bacillariophyceae, Chlorophyceae, and Cyanophyceae as well as 1 species of Zooplankton (Ciliata). This research also found the Shannon-Wiener diversity index (H') between 1.555 and 1.559; This shows the moderate stability of the plankton community and is supported by a water temperature of 28°C and adequate phosphate and nitrate content.

Abstract

Domestic wastewater was collected from a drainage system on Soekarno Hatta Street, Kalibalau Kencana, Kecepatan District, Bandar Lampung City, with a high Chemical Oxygen Demand (COD) content of 4,867 mg/L. If the wastewater is discharged directly into water bodies, it can reduce the availability of dissolved oxygen, potentially disrupting the survival of aquatic organisms. This research aims to determine the effect of contact time on the reduction of COD levels in domestic wastewater, the effect of fly ash adsorbent both activated and non-activated on the reduction of COD values, and its impact on other parameters according to domestic wastewater quality standards. Fly ash was activated using 6M NaOH and heated at 160°C for 1 hour. The adsorption process was carried out with varying contact times of 30, 60, 90, 120, and 150 minutes, using both activated and non-activated adsorbents with masses of 1.5 and 3 grams. The results of this study showed that the adsorption test with the activated adsorbent with masses of 1.5 and 3 grams reached optimum times of 90 and 60 minutes, respectively, with percentage reductions of 98.78% and 99.03%. In contrast, for the non-activated adsorbent with masses of 1.5 and 3 grams, optimum times occurred at 150 minutes, with percentage reductions of 95.64% and 90.79%, respectively.

Abstract

Batik production process generates liquid waste primarily from dyeing and de-waxing processes. This waste, if not managed properly, can pose environmental challenges. This study explores the potential of Eco-photocatalysis using TiO2 (Titanium Dioxide) for treating wastewater from the batik industry. The process involves utilizing ultraviolet (UV) light and a catalyst to enhance the degradation of parameters such as pH, TSS (Total Suspended Solids), and color. Using a reactor containing four 8-watt UV lamps and maintained agitation at 1100 rpm. The catalyst used is Titanium Dioxide (TiO2) (3 grams). The procedure encompassed varying contact times (60, 120, and 180 minutes) and lamp quantities. The results demonstrate that TiO2-assisted Eco-photocatalysis effectively reduces organic and inorganic pollutants in treated water till pH, 6,73, TSS 70 mg/L and color 0,99 Pt-Co.
