Anaerobic Decomposition

Production of Biogas from Cow Manure and Chicken Manure with Addition of Papain. Farms not only contribute positively to meet the demands of protein and increase incomes but also have a negative impact on the environment due to their wastes, especially manure. Biogas produced from the anaerobic decomposition of organic waste is a solution of manure utilization to be a fuel which is cheap and environmentally friendly. To accelerate the production of biogas it is needed a proteoloitik enzyme from papaya, which is called papain. This study aims to calculate the production of biogas from cow manure and chicken manure with addition of papain. The experiments were conducted in the digester made from plastic drums and observed for 30 days. The results showed that the papain influenced of production acceleration of biogas from cow manure. Comparison of biogas production in a week from cow manure: cow manure + 2 kgs of papaya pieces: cow manure + 4 kgs of papaya pieces are 202.7 liters: 263 liters: 332.3 liters. Cow manure did not need other ingredients except water with ratio 1: 1½ . Chicken manure had not been able to produce biogas because their CN ratio was not eligible, although the chaff had been added to increase the carbon content. Biogas from cow manure with addition of papain can be applied on a wider scale, while biogas from chicken manure requires other ingredients that biodegrade easier to add C content in the mixture. Keywords : biogas; cow manure; chicken manure; papain

Abstract Cow manure, chicken manure, and organic waste are solid wastes that can be used as an energy source through a biogas digester. This study aims to determine the production of biogas from waste in a batch digester system. This research uses a digester in the form of a plastic drum with a capacity of 220 liters. 3 treatments were consisting of digester 1 containing cow manure and water (50:50), digester 2 in the form of a mixture of cow manure, chicken manure, and water (30:20:50), digester 3 containing cow manure, organic waste, and water (30:20:50). The digester is then closed tightly for 130 days. The results showed that the daily temperature ranged between 26°−31°C and the acidity (pH) 7-7.62. The biogas production of each digester was then carried out a flame test with a biogas stove. The results of the gas stove flame test show that digester 2 has a longer total flame period of 4302 seconds, then digester 1 has a total flame period of 4034 seconds and lastly, digester 3 has a total flame period of 2370 seconds.

AbstractProcessing organic waste using black soldier fly (BSF)-based technology offers a promising alternative for sustainable organic waste management and urban sanitation. This study was conducted to assess the influence of feeding strategies on the efficacy of BSF larvae to recycle organic wastes into value products. Fruit waste and chicken manure were used as organic waste samples while commercial chicken feed was used as a control, and were processed for 15 days in circular plastic containers (Ø 30 × 12 cm) with 50; 100; 150; and 200 mg/larva/day continuous and batch feeding diets, using 500 four-day-old larvae per diet, repeated four times. Larval survival rates were not significantly affected by the feeding strategies. However, average larval biomass of 83.69 ± 13.04 g and 82.46 ± 08.52 g was achieved for the continuous and batch feeding strategies, respectively, under favorable conditions. Larval feed reduction rates ranged from 24.65 ± 03.48% to 72.78 ± 01.48% and 24.52 ± 0.27% to 72.25 ± 12.13% with continuous and batch feeding strategies, respectively, and were significantly affected by the different daily diets. On the other hand, the bioconversion rates ranged from 13.34 ± 0.26% to 50.82 ± 02.27%, and the highest values were observed with the continuous feeding diets. This study confirms the efficacy of BSF larvae to thrive in different organic substrates and shows that the continuous feeding strategy can be better and enhance a sustainable small-scale organic waste management.

Using organic wastes as agricultural amendments is a productive alternative to disposal in landfills, providing nutrients for plant growth and carbon to build soil organic matter. Despite these benefits, a large fraction of organic waste is sent to landfills. Obstacles to the adoption of wastes as sources of plant nutrients include questions about harmful effects to crops or soils and the wastes’ ability to produce satisfactory yields. We compared six organic waste amendments with a mineral fertilizer control (CN) to determine effects on soil quality, soil fertility, crop quality, and crop yield in 2013 and 2014. Waste amendments were applied at a rate sufficient to supply 10,000 kg organic C/ha over two seasons, and mineral fertilizer was applied to control plots to provide 112 kg-N/ha/yr. The experiment was laid out in a randomized block design with four replicates and three crops: sweet corn (Zea mays L. cv. Applause, Brocade, and Montauk), butternut squash (Cucurbita moschata Duchesne cv. JWS 6823), and potatoes (Solanum tuberosum L. cv. Eva). Amendment with biosolids/yard waste cocompost (BS), dehydrated restaurant food waste (FW), gelatin manufacturing waste (GW), multisource compost (MS), paper fiber/chicken manure blend (PF), and yard waste compost (YW) did not have a negative impact on soil moisture, bulk density, electrical conductivity (EC), or the concentration of heavy metals in soil or plant tissue. Our results indicate potential uses for waste amendments including significantly raising soil pH (MS) and increasing soil organic matter [OM (YW and BS)]. The carbon-to-nitrogen ratio (C:N) of waste amendments was not a reliable predictor of soil inorganic N levels, and only some wastes increased potentially mineralizable nitrogen (PMN) levels relative to the control. Plots amended with BS, FW, and GW produced yields of sweet corn, butternut squash, and potatoes comparable with the control, whereas plots amended with YW, PF, and MS produced lower yields of sweet corn, squash, or both, although yields for potatoes were comparable with the control. In addition, the marketability of potatoes from PF plots was significantly better than that of the control in 2014. None of the wastes evaluated in this study had negative impacts on soil properties, some provided benefits to soil quality, and all produced comparable yields for at least one crop. Our results suggest that all six wastes have potential to be used as sources of plant nutrients.

Water spinach (Ipomoea reptans Poir) had been identified as a nutritious vegetable with high demand in Indonesia. Besides, this plant also has been evidenced to play an important role in environmental cleaning as phytoremediator. The study about the effect of organic fertilizers on the growth and yield of water spinach (Ipomoea reptans Poir) has been conducted in the Green House of Biology Department, Faculty of Mathematics and Natural Sciences, Universitas Negeri Medan. The study aims to investigate the most effective type of fertilizers and the dose for water spinach’s (Ipomoea reptans Poir) growth and yield. A Completely Randomized Factorial Design was designed for the experiment with two factors and three repetitions. The first factor is the type of fertilizer (chicken manure, cow manure, and compost), and the second factor is the dose of the fertilizer (1:1, 2:1, and 3:1). The parameters such as plant height, number of shoots, number of leaves, fresh weight, dry weight, leaf’s total chlorophyll content, and water content were measured to evaluate plant growth and yield. The General Linear Model used SPSS 21 programs was applied to analyze the collected data. Study results revealed that cow manure increased plant growth and yield significantly with dose 2:1 as the finest treatment, followed by dose 3:1. Cow manure also increased total chlorophyll content (8.0574c mg. L-1), with the most suitable dose was 2:1 (8.2807 mg. L-1). The plant’s water content tended to be high in chicken manure (93%), and the lower water content was in cow manure with dose 3:1 (87.5%).
