Adsorption Treatment

The batik industry produces liquid waste from the coloring, washing and rinsing processes. This study was aimed to analyze the quality of Banten batik effluent before and after treatment. The processing is carried out using an experimental method with a batch system by coagulation using alum and adsorption using Bayah's natural zeolite by performing 3 variations of coagulant mass and adsorbent for the dye test parameters, TDS and TSS. The results of the test before treatment were the results for dyes of 344 TCU, TDS 620 mg/L, and TSS 218.5 mg/L. Based on the coagulation treatment using alum, the most efficient coagulant results were obtained to reduce the levels of dyestuffs and TDS, namely by using alum coagulant as much as 1500 mg/L which resulted in 96.6 TCU and 330.0 mg/L respectively, then to reduce TSS levels obtained an efficient coagulant that is 500 mg/L with a yield of 10 mg/L. The adsorption treatment using Bayah natural zeolite can reduce the levels of TDS and TSS with the most efficient results using an adsorbent of 150 g/L obtained for TDS 189.3 mg/L and TSS 13.3 mg/L. So based on the results of processing using coagulation and adsorption methods, it is hoped that the batik industry can apply it in processing the liquid waste produced.

Introduction: The use of detergent every year is increasing in line with the population growth rate in Indonesia. The impact of excessive use of detergent will result in pollution and damage to ecosystems and aquatic biota. The nature of detergents is to damage microorganisms. The dominant laundry waste comes from softeners and detergents. The research aimed to analyze the effectiveness of the "SM" tool to reduce detergent levels in laundry wastewater. Methods: This type of research was pre-experimental with a one-shot case study design. The independent variable was a tool to recycle laundry liquid waste into clean water "SM." The dependent variable was the detergent level (MBAS). The sample came from the laundry in the Kecamatan Baturraden area. Replication was carried out six times. Analyzing differences in detergent levels before and after being treated with the "SM" tool. The analysis used a paired T test. Result and discussion: The experimental results showed the “SM” tool could treat 960 liters of wastewater/day. The physical quality of the water after being treated using the “SM” tool, the water was colorless or clear, but it still smelled slightly fragrantly. The average level of detergent level checks before processing was 2.52 mg/L and after processing was 0.01 mg/L. The effective detergent parameter (MBAS) decreased by 99.51%, categorized as quite effective. The analysis using the paired T Test showed the p value of 0.239 with the lower and upper values being at one pole, meaning there was a significant difference between detergent levels before and after being processed utilizing the "SM" tool. Conclusion: Detergent levels (MBAS) after processing met the chemical quality requirements of clean water in accordance with Regulation of the Minister of Health Number 32 of 2017 concerning Environmental Health Quality Standards and Water Health Requirements for Sanitation Hygiene, Solus Per Aqua and Public Bathing Needs.

Kinetic regularities of adsorption treatment of phenolic wastewater with glauconite have been revealed. It was found that glauconite at a dose of 2 g/dm3 in combination with a 0.1% solution of cationic flocculant, which provides removal of resinous substances up to 94% for 10 min and phenols up to 20% during 20 min. As a result, the MPC of phenols and resinous substances was achieved at the stage of mechanical treatment of effluents, which are then fed for biochemical processing into aeratanks, which is 415 mg/dm³ and 25 mg/dm3, respectively. The dispersed composition of sediments after treatment of industrial wastewater with glauconite was studied. It was found that the particle radii of the polydisperse system "liquid waste  – glauconite" in combination with cationic flocculant were the largest and reached r = 537 mkm, which is twice the maximum polydisperse systems "liquid waste  – glauconite" and "liquid waste  – glauconite" with an anionic flocculant. Sedimentation analysis showed that the sedimentation time of the sediment decreased from 17 min to 6 min in the system "liquid waste  – glauconite" in combination with cationic flocculant and formed a precipitate of loose flakes, which settled quickly. The introduction of a flotation plant with a dosage of natural glauconite 2 g/dm3 in combination with a 0.1% solution of cationic flocculant at industrial treatment facilities is proposed. Engineering solutions will improve the quality of wastewater supplied for coke quenching and will make it possible to transport and dispose of sludge after waste treatment with glauconite, which is planned to be used as a raw material for the manufacture of pavements in asphalt plants.

The Difference

A study on adsorption of AFB1 in corn (kernel and grained) on natural zeolite and bentonite has been investigated. The first work was adsorption in a batch system of standard AFB1 solution on adsorbents. Some factors such as contact time, concentration of AFB1 and particle size of adsorbent were evaluated. The amount of AFB1 adsorbed was calculated based on the difference of AFB1 concentration before and after adsorption determined by high performance liquid chromatography (HPLC) method. Adsorption of AFB1 in corn sample was emphasized by mixing aqueous suspension of sample with adsorbent. Concentration of AFB1 in suspension was analyzed by enzyme-linked immuno-sorbent assay (ELISA) method. Result shows that adsorption of AFB1 on adsorbents of natural zeolite and bentonite is very fast. Within 15 min 99% of AFB1 (200 ng/mL) has been adsorbed by 25 mg of bentonite and 96% by zeolite. The particle size higher than 200 mesh did not give significant effect on the AFB1 adsorption capability. Effectiveness of zeolite in adsorbing AFB1 is lower than that of bentonite. Capability in reducing AFB1 contamination in corn samples (kernel and meal) for both adsorbents is lower than that in standard solution.

The Impact

Zakat is one of the five pillars of Islam which has a function of faith, social and economic functions. Muslims who can pay zakat are required to give at least 2.5 per cent of their wealth. The problem of poverty prevalent in disadvantaged regions because of the difficulty of access to information and communication led to a gap that is so high in wealth and resources. The instrument of zakat provides a paradigm in the achievement of equitable wealth distribution and healthy circulation. Zakat potentially offers a better life and improves the quality of human being. There is a human quality improvement not only in economic terms but also in spiritual terms such as improving religiousity. This study aims to examine the role of zakat to alleviate humanitarian issues in disadvantaged regions such as Sijunjung, one of zakat beneficiaries and impoverished areas in Indonesia. The researcher attempted a Cibest method to capture the impact of zakat beneficiaries before and after becoming a member of Zakat Community Development (ZCD) Program in material and spiritual value. The overall analysis shows that zakat has a positive impact on disadvantaged regions development and enhance the quality of life of the community. There is an improvement in the average of mustahik household incomes after becoming a member of ZCD Program. Cibest model demonstrates that material, spiritual, and absolute poverty index decreased by 10, 5, and 6 per cent. Meanwhile, the welfare index is increased by 21 per cent. These findings have significant implications for developing the quality of life in disadvantaged regions in Sijunjung. Therefore, zakat is one of the instruments to change the status of disadvantaged areas to be equivalent to other areas.
