Abstract

Pluchea Indica L. or beluntas plant is a medicinal plant that contains several bioactive components including tannins, alkaloids, flavonoids, saponins and essential oils. The flavonoids in beluntas leaves can act as antioxidant, anticancer and antidiabetic compounds. This research aims to determine the effect of fermentation time and maceration time and to obtain the best conditions for the flavonoid levels of beluntas leaf extract. One way to obtain high amounts of beluntas leaf flavonoids is by maceration extraction with fermentation of Rhizopus sp. This research was carried out by fermenting beluntas leaf powder using Rhizopus sp at a temperature of 30°C and aerobic conditions with a time of (48; 72; 96; 120; 144) hours. After fermentation, the beluntas leaf powder will be analyzed using UV-Vis spectrophotometry. Next, the beluntas leaf powder will be extracted using the maceration method using 90% methanol solvent with a maceration time (24; 36; 48; 60; 72) hours, then filtered to separate the filtrate and sediment. The filtrate was distilled to obtain beluntas leaf extract, then the beluntas leaf extract was analyzed for flavonoid levels using the UV-Vis Spectrophotometry method. The results showed that fermentation time and maceration extraction time had an effect on the flavonoid content of beluntas leaf extract. The best flavonoid content was obtained at 1.0398% at a fermentation time of 96 hours and a maceration time of 48 hours.

Abstract

Many industries in Indonesia have switched to using coal fuel. The use of coal at PT PLTU Paiton has reached 250 tons per hour and produces 4% of waste by-products of combustion contained from bottom ash by 25% and fly ash by 75%. Fly ash waste will harm the environment and health. Fly ash contains many components, including SiO2 52%, Al2O3 31.86%, Fe2O2 4.89%, CaO 2.68%, and MgO 4.66%. This research aims to synthesize and characterize zeolite X from PT Paiton fly ash using a low-temperature synthesis method. Zeolite X synthesis in this study has 3 steps: The pretreatment process, silica synthesis process, and zeolite synthesis process. The results of silica synthesis obtained SiO2 55.54%. The resulting zeolite product has a typical peak at 2Ï´ 28.72. Zeolite x has a wavelength of 430, 570, 695,7, and 965,7, which respectively indicates Si-O-Si and Si-O-Al bonds, double ring bonds, T-O ring symmetric strain (internal), and asymmetric (internal). The results of zeolite X crystal synthesis in this study could not be formed in the variable of adding time of 3-5 hours with a variation of moles of Al2O3 0,5-1,5 moles.

Abstract

Furniture production made from mahogany wood produces sawdust that contains biomass such as cellulose, hemicellulose, and lignin. The lignin content in mahogany wood can be used as raw material for making sodium lignosulfonate surfactants. Delignification of lignin is carried out alkaline and continued with lignin isolation by acid precipitation. Pure lignin isolate is further used as a raw material for making sodium lignosulfonate surfactants using the sulfonation process. The sulfonation process is carried out by mixing lignin isolate and sodium bisulfite solution using excess NaHSO3 variation and sulfonation time. Both variables are run by adding sodium hydroxide as a catalyst and the pH condition was maintained at pH 4. The sodium lignosulfonate surfactant solution formed was then characterized using FT-IR spectrophotometer and UV-Vis spectrophotometer. The best condition was obtained at a sulfonation time of 150 minutes and NaHSO3 exceeded 75%, namely with a surfactant concentration of   4100,784 mg/L.

Abstract

Indonesia, as an archipelagic country, boasts extensive and diverse coastal resources. Sustainable management of coastal areas is crucial to ensure long-term benefits for communities. One recently opened tourist destination is Karang Empat Beach, located in Ranokomea Village, West Poleang District, Bombana Regency. Despite its high tourism potential, the beach faces serious issues related to waste accumulation, particularly plastic waste, caused by a lack of visitor awareness and inadequate disposal facilities. To address this problem, a dedicated team conducted a series of activities, including the provision of trash bins, beach clean-up efforts, and the installation of informational boards to raise public awareness. The positive response from local authorities further supported these efforts. The results of these activities demonstrated a reduction in waste on the beach and an increase in public awareness about proper waste disposal. This study highlights the importance of collaboration between communities and management in maintaining cleanliness and ensuring the sustainability of tourist areas.

Abstract

PT. Candi Jaya Amerta is an industry that produces fly ash from coal combustion in boilers and wastewater from its production processes. The utilization of fly ash in this industry has not been well optimized, and the wastewater is characterised by elevated concentrations of organic matter, primarily generated from shrimp cracker production. High organic content in wastewater can lead to environmental pollution. Goal of this research is to determine the effect of sampling time on the reduction of Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD) levels in the wastewater of PT. Candi Jaya Amerta using fly ash adsorbent through a column adsorption process system, employing the Yoon-Nelson, Adam-Bohart, and Thomas approaches. The variables employed in this study are sampling times of 20, 40, 60, 80, and 100 minutes, and adsorbent heights of 9, 13, 17, 21, and 25 cm. The research findings show that the optimal adsorbent height for reducing COD is 21 cm, with a reduction percentage of 88.2705% and a COD adsorption capacity of 7.2593 mg/g at a sampling time of 60 minutes. Meanwhile, the optimal adsorbent height for reducing BOD is 25 cm, with a reduction percentage of 98.1509% and a BOD adsorption capacity of 87.4255 mg/g at a sampling time of 60 minutes.

Abstract

Coal fly ash is a significant byproduct of coal combustion that poses environmental risks if not properly utilized. Rich in aluminosilicates and naturally porous, fly ash can serve as an environmentally friendly, low-cost adsorbent for industrial wastewater treatment. This study aims to investigate the effect of HCl concentration and activation time on the characteristics and adsorption capacity of coal fly ash as an adsorbent. Chemical activation with HCl was performed to enhance adsorption capacity by dissolving impurities, increasing pore volume, increasing surface area, and improving silica content while reducing aluminium levels. The results indicated that the HCl-activated fly ash exhibited the highest iodine adsorption value of 778.38 mg/g, exceeding the SNI standard of 750 mg/g, demonstrating excellent adsorption performance. XRF analysis revealed 78.1% SiO? and 3.96% Fe?O? contents, suggesting that HCl-activated fly ash has great potential as an effective, economical, and sustainable adsorbent for industrial wastewater treatment.

Abstract

Laundry wastewater poses thousand risk for the environment and microbes due to its detergent content that remain the same from washing process using detergent and any other substance. These detergents can trigger various issues such as eutrophication in rivers and health problems caused by their chemical components. Therefore, further treatment is necessary to ensure the wastewater meets quality standards and is safe for discharge into the environment. Fly ash, which contains a high concentration of aluminum, can be utilized through a synthesis process to produce alum. This alum is then applied in coagulation–flocculation processes to reduce pollutants in laundry wastewater, such as BOD, COD, and TSS. This study aims to determine the optimal dosage and contact time of fly ash alum in treating wastewater to meet quality standards, using dosage variations of 30, 40, 50, 60, and 70 mL and flocculation times of 45, 55, 65, 75, and 85 minutes. The results of the treatment using fly ash alum are then compared with those using commercial alum to identify the most effective treatment. Consequently, the synthesis and treatment process not only contribute to wastewater management but also offer an alternative solution for coagulant and flocculant materials.
