Abstract

ABSTRAK. Logam berat  Pb merupakan logam berat yang berbahaya bagi kesehatan. Logam Pb dapat merusak sistem organ. Salah satu cara untuk mengurangi adanya kandungan logam Pb dapat dilakukan dengan penggunaan adsorben. Keong mas merupakan salah satu hama bagi aktivitas pertanian. Di dalam cangkang keong mas mengandung banyak kalsium karbonat. Kalsium karbonat dapat dijadikan sebagai adsorben. Penelitian ini bertujuan untuk menguji keefektivan serbuk cangkang keong mas dalam menyerap logam Pb. Penelitian merupakan penelitian kuantitatif. Terdiri dari variabel terikat dan variabel bebas. Variabel terikat terdiri dari konsentrasi 10 ppm timbal dn kecepatan waktu pengadukan 100 rpm. Sedangkan variabel bebas terdiri dari variasi massa serbuk dan waktu pengadukan. Massa serbuk keong mas yang digunakan yaitu 0 gr; 5 gr; 10 gr; 15 gr dan 20 gr dengan variasi waktu pengadukan selama 15 menit dan 30 menit untuk tiap sampel Pb. Tiap Pb yang digunakan dengan konsentrasi 10 ppm. Berdasarkan hasil perhitungan yang diperoleh didapatkan hasil efektivitas serbuk cangkang keong mas dalam menyerap Pb 10 ppm terdapat pada massa 5 gr serbuk cangkang keong mas dan dengan waktu pengadukan 15 menit yaitu sebesar 99,99% dengan hasil penurunan konsentrasi Pb 10 ppm menjadi Pb 0,0001 ppm

Abstract

Waste is an integral part of human life. The increase in population is one factor that increases the waste generated. The more the population, the more activities are carried out. Organic leachate and rice washing water are environmentally friendly compost activators and are easily obtained from daily activities. Composting is a waste management strategy. Composting is an organic method through the activity of microorganisms to decompose natural materials into materials, including humus. The purpose of this study was to determine the moisture content, temperature, pH, C/N ratio, and macro nutrients during the composting process. The physical parameters of compost from the three activator concentrations showed that the treatment of P3 (with the addition of leachate formulation 20 ml/kg and rice washing water 15 ml/kg) and P2 (with the formulation adding 20 ml/kg leachate and 10 ml rice washing water), the physical compost were brownish black in color, fine textured and smelled of soil on the 22nd day. The P3 treatment has met the quality criteria of compost according to  SNI 19-7030-2004, the moisture content (30%), temperature (27°C), pH (6,8), C-Organic (32,9%), Nitrogen (1,42%), Phosphor (0,65%) and Potassium (1,63%). For the C/N ratio, the result of all treatments did not meet the quality criteria of compost according to SNI 19-7030-2004. The C/N ratio of all treatments showed that it is still above the maximum standard that has been set at 20.

Abstract

The presence of microplastics in aquatic sediments is a threat to biota that live in waters, especially fishes. This study aims to determine the presence of microplastics in sediments and Kuwe fish (Caranx sp) in the coastal waters of Gampong Jawa Banda Aceh. This research processes begins with sampling, sample preparation, identification of microplastics, and Fourier Transform Infrared Spectroscopy (FT-IR) testing to determine the type of polymer as the origin of the microplastics in the fish samples. Several types of microplastics that have been identified are fragments, fibers and films. The colors of the microplastics found were brown, transparent, black, blue and red. The abundance of microplastics found in sediment was 1630 particles/kg, while the abundance of microplastics found in fish, namely in the organs of the digestive tract and in the fish's body with an abundance of 975 particles/kg and 135 particles/kg respectively. The results of FT-IR analysis have verified several types of polymers such as Polypropylene (PP), Polystyrene (PS), Poly (methyl methacrylate), Ethylene Vinyl Acetate (EVA), Nylon, High-Density Polyethylene (HDPE), and Low-Density Polyethylene (LDPE), with appropriate functional groups. The discovery of microplastics in the coastal waters of Gampong Jawa Banda Aceh indicates microplastic contamination. Therefore, preventive efforts are needed to reduce the abundance of microplastics in these waters.

Abstract

Leachate is a liquid waste formed due to water seepage into waste piles containing high concentrations of organic and inorganic compounds that have the potential to pollute the environment. This study aims to evaluate the effectiveness of Azolla microphylla plants in reducing leachate pollutant parameters from the Blang Bintang TPA through the phytoremediation method. Variations of treatments include plant masses of 300 and 400 grams and residence times of 7 and 14 days. The parameters analyzed include Chemical Oxygen Demand (COD), Total Suspended Solid (TSS), and Biochemical Oxygen Demand (BOD). The results showed that the best treatment was obtained at a plant mass of 400 grams with a retention time of 14 days, with the effectiveness of reducing COD by 22.95% (from 758 mg/L to 584 mg/L), TSS by 60.80% (from 523 mg/L to 205 mg/L), and BOD by 22.40% (from 424 mg/L to 329 mg/L). Although it has not met the leachate quality standards based on Permen LHK No. 59 of 2016, the use of Azolla microphylla shows potential as an environmentally friendly phytoremediation agent. It can be further developed as part of a sustainable leachate treatment system.

Abstract

Oil contamination in the soil might cause degradation on the quality of the soil, which becomes a problem for the environment and the organisms in it, especially the plants. The plants will be unable to grow and develop properly in the degraded soil, which will give a severe negative impact to agricultural sector. Biostimulation can be a good solution in solving soil degradation problem, utilizing microorganisms and biostimulant. The objective of this study is to discover the potential of chicken manure as biostimulant for biostimulation process in the removal of total petroleum hidrocarbon (TPH) as one of the main properties in oil contaminant. In this study, the chicken manure as biostimulant were being mixed with the oil contaminated soil (400 gr), with variation of weight; W1= 50; W2= 100; W3= 150; and W4= 200 gr. Biostimulation process were being observed and analyzed every 7 days for 21 days, and being compared with the soil without biostimulant addition (control). The result shown that biostimulation process using chicken manure in this study can remove up to 66.67% of TPH, from 6% of to 2% (W4 for 21 days), but still unable to fulfill the quality standard given, which is 1%. Based on the result of this research, it can be concluded that biostimulation using chicken manure as biostimulant can be utilized to remove TPH from oil contaminated soil, hence still need improvement to perform better.
