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.

Abstract

Pengabdian kepada masyarakat merupakan salah satu dari Tri Dharma perguruan tinggi bagi masyarakat. Air cucian beras dan juga limbah dapur merupakan sampah organik yang jarang dimanfaatkan sebagai salah satu alternatif pupuk yang ramah lingkungan. Sebagian besar sampah dapur dapat dijadikan pupuk kompos maupun pupuk cair. Tujuan dilakukan pengabdian ini adalah untuk memberikan edukasi bagi masyarakat tentang pemanfaatan limbah dapur dan juga air cucian beras sebagai salah satu unsur hara alami bagi tanaman. Dengan cara ini diharapkan dapat mengurangi sampah organik rumah tangga. Metode yang digunakan dalam pengabdian ini berupa pemberian penyuluhan dan praktek pembuatan pupuk. Bahan yang digunakan berupa air cucian beras, gula merah dan juga sisa sampah dapur. Campuran tersebut difermentasi selama 7-10 hari. Selama proses ini berlangsung, tutup wadah dibuka sesaat untuk mengurangi kebocoran wadah akibat gas-gas hasil fermentasi yang dihasilkan oleh bakteri. Hasil fermentasi air cucian beras dan juga limbah dapur setelah 7-10 hari berwarna kecoklatan dan berbau sedikit asam. Hasil pengabdian ini berupa pupuk organik cair yang siap diaplikasikan bagi tanaman. Pengaruh pemberian pupuk terhadap tanaman belum dilakukan karena keterbatasan waktu dan akan dilakukan survei pada agenda kegiatan pengabdian berikutnya di Desa Lamreh.

Abstract

Palm oil processing resulting empty fruit bunch waste that has a high organic content. Empty fruit bunches produce up to 6 million tons of waste per year and this waste has not been widely utilized so that can become an environmental problem such as pollution in the future. Alternative way to utilize the wastes is by converting them into organic fertilizer or compost. Therefore, this study aims to analyse and compare the results of EM4 activator composting by using leachate activators, the effect of composting time for each activator and the quality of compost referring to SNI 19-7030-2004. In this study, the composting process was carried out for 21 days with three experiments that include without treatment, by adding 1 litre of EM4 activator and by adding of 1 litre leachate water. The parameters measured were physical, temperature, humidity, pH, C, N, P, K and C/N-ratio. The results of this study indicate that composting with EM4 activator resulting composting pH level of 4.4 - 6.2, humidity of 1.5 - 70%, temperature of 29-38 °C, brownish black in colour, rough and hard in textures and soil-like (earthy) smell while composting using leachate water has a pH of 4.6 - 6.5, humidity of 3.9 - 80%, temperature of 29-38 °C and brownish black in colour, rough texture and slightly stink. Compost with EM4 activator was showing a faster composting time than using leachate. In term of quality, the composting by using EM4 activator produced higher quality compost compared to leachate activator composting with compost quality close to SNI 19-730-2004 requirement.

Abstract

One way to reduce organic waste is through composting. One composting methodhat can be used is the Mac Donald method which employs an aerobic system to place raw ingredientsn an open box-shaped container. The purpose of this experiment was to observe the object under this study (rice washing water in organic waste composting). Four compost treatments namely P0 (organic garbage and without rice washing water added); P1 (organic garbage and added rice washing water of 35 ml); P2 (organic garbage and added rice washing water of 45 ml) and P3 (organic garbage and added rice washing water of 55 ml). Temperature measurements at the end of the composting process showed that the temperature in all four containers was 29°C. The pH values obtained met maturity requirements forompost as specified by SNI 19-7030-2004, namely with a minimum value of 6.80 and a maximum of 7.49. The observation results of moisture content at the end of composting in the four containers were 40%. The best results were shown in the variation of P2 (by added rice washing water of 45 ml) with a C/N ratio of 19.31 and began to mature in week 3 with levels of C-organic, N-total, P-total and K-total of 34.00%; 1.76%; 0.49% and 1.68% respectively.
