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

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.

Abstract

The contribution to the increase in CO2 emissions can come from all the activities of construction workers who use energy such as the procurement of building materials, the use of transportation fuels, the activity of using electricity, and the activity of using LPG. The carbon footprint is a measure of the total amount of carbon dioxide (CO2) emissions originating from activities or the accumulation of daily activities. carbon footprint calculation using the IPCC 2006 method. The carbon footprint calculation results obtained from the development activities of the Miftahun Najah Islamic boarding school building in the procurement of building materials resulted in a carbon footprint of 2.8417 tons. CO2-eq, trucking activities, construction workers produced 550.7 tons. CO2-eq, the activity of using electricity produces a carbon footprint of 39.403 ton.CO2-eq/kWh, and the activity of using LPG produces a carbon footprint of 0.11 ton.CO2-eq. The purpose of measuring the quality of Carbon Dioxide (CO2) is to determine the concentration of CO2 during the development of buildings at the Miftahun Najah Islamic Boarding School.

Abstract

The aim of this research is to determine the feasibility of producing environmentally friendly briquettes using organic waste and coconut shells as the main ingredients. 3 (three) briquette compositions, including: (1) 25% organic waste, equivalent to 75% coconut shell; (2) 75% organic waste, 25 percent coconut shell; and (3) 50% organic waste, 50 percent coconut shells. The research method used to analyze the water content, ash content and heating value of briquettes is a quantitative research method. The results of this research show that organic waste and coconut shells can be converted into environmentally friendly briquettes. Briquettes with a mixture composition of 75%:25% have a reduced ash percentage. Meanwhile, mixed briquettes containing 25%:75% have a low water content, meaning more coconut shell, the lower the water content and the better the properties of the briquettes.

Abstract

Sewage sludge is a major by-product of the wastewater biological treatment process. Wastewater Treatment Plants at Palm Oil Mills (PKS) produce a lot of sewage sludge and until now it has not been optimally utilized. This study aims to examine the potential of PKS sewage sludge as an adsorbent for the removal of kromium (Cr) by the fixed bed column method. The study will also analyze the effect of recirculation on the reduction of kromium levels. The sludge was carbonized in a furnace at 300°C for 2 hours. Synthetic kromium wastewater was made at three concentrations of 2000 ppm, 3000 ppm, and 4000 ppm. The sludge adsorbent used was 100 grams which was filled into the fix bed column. Recirculation of kromium wastewater was performed 3 times. Adsorption isotherms were analyzed using Langmuir and Freundlich models. The results showed that the best removal without recirculation occurred at a kromium concentration of 3000 ppm with a removal efficiency of 48.07%. Furthermore, recirculation was carried out 3 times and resulted in varying removal values at the 1st, 2nd, and 3rd recirculation of 37.9%, 40.06% and 35.4%. The highest removal occurred in the second recirculation. The addition of recirculation led to a decrease in the sorption of chrome as the adsorbent had reached saturation point. This allows the release of kromium ions that have been adsorbed and causes the removal efficiency to decrease. A suitable adsorption isotherm model for sludge adsorbent is the Langmuir model, where the adsorption process occurs in a single layer and is homogeneous.
