Circular System

Bioenergy production from animal waste can be a key driver to achieving bio-economy goals. Developing a bio-economy sector could help to create opportunities for a circular system where not only people and the planet will be benefited, but it will also provide economic profitability to farmers, especially in the post-Covid period. To this end, manure production, its nutrient content, and bioenergy potential were estimated, along with their spatial distribution in the Lubelskie province, Poland. Farm-level data were processed and aggregated at the municipality level. Material balance equations were used to calculate the theoretical potential of livestock manure and bioenergy for different use scenarios: (1) Baseline (BC): direct manure application to land, which was compared against (2) Anaerobic Digestion (AD): anaerobic digestion to biogas with digestate returned to the fields (3) AD + Separation (AD + Sep): mechanical separation followed by anaerobic digestion, and (4) Surplus + AD: surplus manure (after application to the fields) is sent to anaerobic digestion. Manure, biogas, electricity, and thermal energy production of the AD scenario were estimated to be 7.5 Mt y−1, 378 Mm3 y−1, 907 GWe y−1, and 997.8 GWth y−1, respectively. The scenario, including mechanical separation followed by anaerobic digestion (AD + Sep), contributed to avoiding emissions to the largest extent (1 Mt CO2 eq), whereas AD outperformed the others in avoiding costs of fertilization. According to the estimated potential and the environmental cost-effectiveness of AD, new plants can be established that will recycle manure through bioenergy production, and, subsequently, the digestate can be applied as organic fertilizer, closing the nutrients cycle.

Abstrak- Limbah cair latex yang dibuang begitu saja akan menimbulkan masalah karena selain dapat menimbulkan bau bagi lingkungan sekitar juga dapat menurunkan kandungan hara dalam tanah dan bila masuk ke badan sungai dapat mencemari sumber air bersih. Dalam proses biogas selain menghasilkan gas yang dapat bermanfaat sebagai energi alternatif, biogas juga dapat menghasilkan produk bawah berupa limbah yang juga mempunyai manfaat. Limbah digester biogas ini baik yang padat maupun cair dapat dimanfaatkan sebagai pupuk organik. Tujuan dari penelitian ini adalah mengetahui potensi produk samping biogas dari limbah cair latex sebagai penghasil pupuk cair sehingga dapat dikembangkan menjadi teknologi baru dalam proses anaerobic digestion dan mengetahui pengaruh penambahan enceng gondok maupun jerami padi pada limbah cair latex terhadap kandungan pupuk kompos cair yang dihasilkan. Berdasarkan hasil penelitian, kondisi operasi yang optimal untuk menghasilkan biogas pada suhu 28 oC dan pH 7 dengan waktu pengujian hari ke-28. Kandungan pupuk cair pada penambahan substrat enceng gondok diperoleh N-total=0,026%, C-Organik=0,081%, P=0,033% dan K=0,423%. Sedangkan untuk kandungan pupuk cair pada penambahan substrat jerami padi sebesar N-total=0,017%, C-Organik=0,186%, P=0,045% dan K=0,358%.

Fertilization is an action in plant care. Fertilization provides additional nutrients for the soil. Fertilization has a large influence on plant growth and production. Fertilization consists of organic and inorganic fertilizers. Both of these fertilizers must be balanced so that the nutrient content can be maintained properly. The use of fertilizers an organic fertilizer that is widely used, but the use of chemical fertilizers on an ongoing basis will reduce the level of soil fertility. This must be balanced with organic fertilizer. One of the organic fertilizer is guano fertilizer. This fertilizer is fertilizer made from animal waste, namely bats. This fertilizer has a very good content including nitrogen, phosphorus, and potassium. Knowledgethis fertilizer will still be low, so that an introduction and practice about guano fertilizer is needed. Therefore a community service activity was carried out on the development of the manufacture of guano fertilizer. Guano fertilizer development is carried out in the form of granules (granules). The targets of this service are vocational students who are related to agriculture. Vocational students are selected as the young generation to know about organic fertilizers and are able to contribute to the implementation of the agricultural industry. Community service activities were carried out with a presentation of the theory and practice of making guano fertilizer. As a result of this activity, students learned about organic fertilizer, namely guano fertilizer and its contents, nutrient content in the soil, balance in maintaining nutrient content in the soil, the practice of making guano fertilizer, and the creation of granule form from guano fertilizer.

Vegetable Cultivation

Vegetable cultivation is livelihoods for side Lake Batur communities, Kintamani, Bangli. Hilly natural conditions with a soil texture influenced by the eruption of Mount Batur, 900 m above sea level, and 900-3500 mm high rainfall, causing this region is very suitable for the cultivation of various vegetables, including shallot. One effort to meet the high demand for shallots is that efforts are made to improve cultivation techniques, including fertilizing to improve yields. In modern agriculture, the use of fertilizer is absolutely essential to trigger the level of crop production. The aims is to analyze the combination effect of using of inorganic fertilizer (ZA fertilizer) and organic fertilizer (compost fertilizer) on shallot vegetable cultivation systems on the content of pollutants, N nutrients and onion crop yields on the shores of Lake Batur, Kintamani District, Bangli Regency. The study using RBD with two factors where factor I: provision of organic fertilizer is leaf compost made aerobically (O), consisted of 3 levels, namely: O0 = 0*, O1 = 5* and O2 = 10*and factor II: the application of inorganic fertilizer namely ZA (S) fertilizer, consisted of 3 levels, namely: S0 = 0**, S1 = 50** and S2  = 100**, each repeated 3 times. The parameters observed were the growth and yield of shallots as well as the content of Pb, Zn, Cu and N nutrients in the soil. The nutrient content (N) in the soil, when using chemical fertilizer ZA and compost organic is not significantly different, as well as the results of onion plants, while the content of Pb, Zn and Cu on the use of chemical fertilizer ZA and organic compost, very real different. The highest soil Pb content in S2O1 treatment is 30.07***, the highest soil Zn content in the S2O1 treatment was 28.24***, and the highest soil Cu content in the S1O2 treatment is 17.22***. *= tons/ha **= kg/ha ***= mg/kg Keywords: compost; contents Pb; Zn; Cu of soil; shallot; ZA.

ABSTRACT The production of Agaricus bisporus results in significant residual material after cultivation. Due to its physical properties and nutrient content Spent Mushroom Substrate (SMS) has great potential for use in agriculture. Our study evaluated the feasibility of using SMS as an alternative substrate for the production of Paronset® hybrid tomato seedlings and as an organic fertilizer in its production. To conduct the fruit production experiment, the plots consisted of three types of fertilizers (SMS of A. bisporus, NPK and bovine manure) with four replications. The seedlings produced in the SMS presented higher rates of germination time and speeds, and stood out from the other substrates in the evaluation of seedling quality. In the tomato fruit production phase, the average production of the plants originating from the SMS was 20% higher than the seedlings from the commercial substrate. The plants cultivated with the SMS presented higher production than the plants cultivated with bovine manure incorporated the soil. According to our results, The SMS was as good as the commercial substrates tested. Therefore, the SMS can be recommended for the growth and nutrition of seedling production and denotes potential viability for use in the tomato production cycle in its different phases.

The Right

The large number of rice fields in Borikamase Village, resulting in high production of hay, requires an appropriate effort to use straw into organic fertilizer or bokashi which is environmentally friendly as well as safe for plants. The use of straw into bokashi or organic fertilizer needs to be taught to the farming community, so the community service team focuses on providing assistance and training to the community in utilizing straw as a raw material in making bokashi by using microorganisms as the source of fermentation. In addition, the high price of synthetic fertilizers on the market makes farmers in Borikamase Village feel heavy in providing nutritional supplies to their agricultural areas, so that this training is expected to help farmers by obtaining fertilizers that are cheap, safe, and of good quality to fertilize. The existence of biotechnology applications, provides the right solution in overcoming the damage to bald mountains and the scarcity and high price of synthetic fertilizers, namely by processing straw into bokashi or organic fertilizers with high nutrient content and are safe for the environment. In addition, providing knowledge and skills for farming communities as agents of reform in restoring ecosystem balance through the application of bokashi made of straw on rice fields.
