This study is attempted to extract the amorphous silica composites using the combined HNO3 leaching-calcination (600°C/6 h) method from corn stalk harvested in Bishoftu, Ethiopia, owning to its profuse dumping, less cost, and negative environmental implications. The resultant composite characteristics such as amorphous nature are connected via the grain boundary which produces an agglomerated structure that has a disordered morphology, and the presence of siloxane and silanol groups, as well as additional functional groups, is reported. The synthesized product is applied in the removal of oil from synthetic oily wastewater (SYOWW) using batch mode delivering a maximum oil removal of up to 99%. The outcome of the study features the potential acclimatization of the Ethiopian corn stalk as a substitute precursor for the production of silica composites which has a potential oil adsorption capacity that can be used for oil spill cleanup.

First Time

Because of the enzymatic make-up of Stropharia, a cultivated and edible mushroom, it is capable of using agricultural wastes as substrates for growth. Different substrates and methods of preparation are compared in order to improve the resistance of the mushroom to fungal contamination by reducing soluble carbon and nitrogen content. The substrates (wheat straw, corn stalk, or wastes from pea plants) were soaked at various temperatures and durations in order to eliminate soluble nutrients. High temperatures are more efficient for a rapid depletion of free nitrogen compounds. The best substrate used for the first time in mushroom cultivation was the agricultural waste from Pisum. Because of its naturally high content of soluble nutrients, this substrate needs to be soaked in hot water to reduce contaminations. Yields of Stropharia (220 g/kg) are higher and more regular than those obtained on conventional substrate (straw). On corn stalk, a high contamination rate was found, as well as relatively poor yields.Key words: mushroom, Stropharia, substrate, waste, yield, fungal contamination.

Ransum adalah gabungan dari beberapa macam bahan pakan ternak yang disusun dengan formulasi tertentu untuk memenuhi kebutuhan nutrisi ternak. Bahan-bahan pakan penyusun ransum yang tersedia di wilayah Lampakuk Kabupaten Aceh Besar seperti: limbah batang jagung, bonggol jagung, dedak padi, kulit kakao, bungkil kelapa, daun ubi jalar dan jerami padi. Bahan-bahan pakan tersebut, selama ini belum dimanfaatkan oleh peternak sebagai bahan – bahan pakan penyusun ransum ternak ruminansia. Kegiatan sosialisasi ini dihadiri oleh 15 orang peternak serta dilakukan dengan metode pemberian materi, diskusi dan praktek langsung penyusunan ransum. Hasil yang diperoleh menunjukkan antusias peternak sapi dalam memanfaatkan limbah pertanian sebagai bahan pakan penyusun ransum menjadi meningkat, sehingga memngkinkan untuk meningkatkan jumlah ternak yang dipelihara. Jika selama ini hanya mengoptimalkan rumput-rumputan dan hijauan sebagai makanan ternak, maka dengan kegiatan sosialisasi ini meningkatkan pengetahuan dan wawasan peternak dalam memanfaatkan limbah pertanian sebagai ransum makanan ternak ruminansia.Kata kunci : Limbah Pertanian, Bahan Pakan, Ransum, Ternak Ruminansia.ABSTRACTThe ration is a combination of several kinds of animal feed ingredients which are arranged in a certain formulation to meet the nutritional needs of livestock. The feed ingredients that make up the ration available in the Lampakuk area, Aceh Besar District, are: corn stalk waste, corn cobs, rice bran, cocoa husk, coconut cake, sweet potato leaves and rice straw. These feed ingredients, so far have not been used by breeders as feed ingredients for ruminant rations. This socialization activity was attended by 15 farmers and was carried out using the method of providing material, discussion and direct practice of preparing rations. The results obtained show that the enthusiasm of cattle farmers in utilizing agricultural waste as feed ingredients for rations has increased, so that it is possible to increase the number of livestock kept. If so far it has only been optimizing grasses and forages as fodder for livestock, then this socialization activity will increase the knowledge and insight of farmers in utilizing agricultural waste as ruminant feed rations.Keyword :Agricultural Waste, Feed Ingredients, Ration, Ruminant Livestock.

In this study, the synthesis of porous beads from corn stalks was carried out. The cellulose extracted from corn stalks was converted into cellulose xanthate and combined with alginate to form porous alginate-cellulose xanthate beads by the ionic gelation method. This study attempted to use sodium chloride (NaCl) as a porogen and zinc acetate as a crosslinker. Beads were characterized to determine the porosity, swelling properties, and functional groups using Fourier Transform Infra-Red (FTIR). The geometry of beads was analyzed by optical microscopy, and its surface morphology was analyzed by Scanning Electron Microscopy-Energy Dispersive X-ray (SEM-EDX). The results showed that corn stalks as agricultural waste material could be used to synthesize porous beads material. The swelling and porosity of beads increased with increasing concentration of NaCl. The presence of porogen has increased beads formation. The results demonstrate the crosslinks between zinc acetate and alginate were successfully characterized using FTIR. NaCl concentration of 9.5% resulted in the highest swelling properties (52.80%) and porosity (81.4%) of the beads.

Earth Blocks

Sustainable development and environmental challenges incite to valorize local materials such as agricultural waste. In this context, a new ecological compressed earth blocks (CEBS) with addition of ground olive stone (GOS) was proposed. The GOS is added as partial clay replacement in different proportions. The main objective of this paper is to study the effect of GOS levels on the thermal properties and mechanical behavior of CEB. We proceeded to determining the optimal water content and equivalent wet density by compaction using a hydraulic press, at a pressure of 10 MPa. The maximum compressive strength is reached at 15% of the GOS. This percentage increases the mechanical properties by 19.66%, and decreases the thermal conductivity by 37.63%. These results are due to the optimal water responsible for the consolidation and compactness of the clay matrix. The substitution up to 30% of GOS shows a decrease of compressive strength and thermal conductivity by about 38.38% and 50.64% respectively. The decrease in dry density and thermal conductivity is related to the content of GOS, which is composed of organic and porous fibers. The GOS seems promising for improving the thermo-mechanical characteristics of CEB and which can also be used as reinforcement in CEBS.

Arjowilangun Village is a post-TKI village. People choose to become sheep farmers with less capital than being cattle farmers. Based on the previous discussion, waste management is required to ensure the sustainability of environment in Arjowilangun Village. Processing sheep and agricultural waste program is held by Doktor Mengabdi team. Farmers can learn how to make Bokashi from waste. The method used is composting aerobic or anaerobic starters for composting organic material. A decomposer as collection of several good microbes from fungi work to control pathogenic microbes assists the fermentation process. Based on the results of the pre-test and post-test during the training, it can be showed that understanding of the breeders' potential of the environment is increased.

Abstract A feasibility analysis of tertiary treatment for Organic Liquid Agricultural Waste is presented using filamentous algae belonging to the genus Cladophora sp. as an alternative to chemical tertiary treatment. The main advantages of tertiary treatments that use biological systems are the low cost investment and the minimal dependence on environmental variables. In this work we demonstrate that filamentous algae reduces the nutrient load of nitrate (circa 75%) and phosphate (circa 86%) from the organic waste effluents coming from dairy farms after nine days of culture, with the added advantage being that after the treatment period, algae removal can be achieved by simple procedures. Currently, the organic wastewater is discarded into fields and local streams. However, the algae can acquire value as a by-product since it has various uses as compost, cellulose, and biogas. A disadvantage of this system is that clean water must be used to achieve enough water transparency to allow algae growth. Even so, the nutrient reduction system of the organic effluents proposed is friendly to the ecosystem, compared to tertiary treatments that use chemicals to precipitate and collect nutrients such as nitrates and phosphates.
