Penurunan kualitas dan produktivitas sumberdaya lahan pertanian terutama disebabkan oleh kandungan C-organik yang rendah dan pemupukan yang tidak diimbangi dengan pupuk organik. Cara mengatasinya adalah mengembalikan bahan organik ke lahan pertanian melalui penggunaan pupuk kompos atau pupuk organik granul (POG) berbahan baku kompos. Pupuk kompos sebaiknya dibuat dari seluruh potensi bahan organik yang ada. Timbulan sampah kota yang besar dengan prosentase bahan organik yang tinggi, memiliki karakteristik yang cocok untuk dijadikan pupuk kompos berkualitas baik, dalam rangka memenuhi kebutuhan pupuk organik. Pupuk komposmemiliki kemampuan untuk memperbaiki dan meningkatkan sifat fisik, biologi dan kimia tanah. Keberhasilan program penggunaan pupuk kompos atau pupuk organic yang lain sangat bergantung kepada dukungan stakeholders terkait, serta kepercayaan petani untuk menggunakan pupuk organik. Dengan ketersedian pupuk organik yang berkualitas, yang diberikan secara berimbang bersama pupuk kimia, maka kualitas dan produksivitas sumberdaya lahan pertanian dapat ditingkatkan sehingga dapat mendukung dan memperkuat kemandirian pangan. Kata Kunci: Sumberdaya lahan pertanian, pupuk organik, sampah kota, kompos, kemandirian pangan. AbstractThe quality and productivity degrade of agricultural land resources mainly due to the low level of C-organic content and the fertilizing that do not use organic fertilizers. The way to solve it is by restoring the organic matter to agricultural land through the use of compost or organic fertilizer granules made from compost. Compost should be made from all organic materials that have potential. The high level of municipal solid waste generation with a high percentage of organic matter, contain the characteristics that are suitable to made a good quality compost, in order to meet the needs of organic fertilizer. Compost has the ability to improve and enhance the physical, biological and chemical soil properties. The successful of compost or other organic fertilizer utilization program is mainly depend on the stakeholders support, as well as the confidence of farmers to use organic fertilizer. With the availability of good quality of organic fertilizer, which is given in a balanced way with chemical fertilizers, the quality and productivity of agricultural land resources can be improved to support and strengthen the food self-sufficiency.Key words: Agricultural land resource, organic fertilizer, municipal solid waste, compost, food self sufficiency.

<p>Biochar application is now considered to be one of the most promising agricultural practices to mitigate climate change. However, to fully assess the benefits of biochar, we still need to better understand its effects on soil properties, and particularly on native soil organic matter (SOM) dynamics.</p><p>In this work, we investigated soil respiration and changes in SOM pools (mineral-free, intra-aggregate, and mineral-associated SOM) as affected by the application of 20 t / ha per year of biochar alone or combined with mineral fertilizer, municipal solid waste compost, or sewage sludge. The experiment was run for 7 years in a semiarid agricultural soil. We found that biochar had no effect on soil respiration with respect to mineral fertilization and no amendment (control), and tended to decrease CO<sub>2 </sub>emissions from soils amended with municipal solid waste compost and sewage sludge. Biochar accumulated mainly in the mineral-free SOM fraction and its addition, especially in combination with municipal solid waste compost, promoted the amount of SOM occluded with aggregates and associated to mineral surfaces.</p><p>Acknowledgments: to the Spanish MICINN (MINECO, AEI, FEDER, EU) for supporting the research project AGL2016-75762-R.</p>

<p>Excessive use of chemical fertilizers may degrade the physical condition of the soil so that solid organic fertilizer was developed. Organic fertilizer was made from organic materials derived from plants or animals that had been made by the engineering process. Organic fertilizers were used to supply organic matter to improve the physical, chemical, and biological properties of soil. This experiment aimed to study the effect of a mixture of bio ethanol solid waste, corn agricultural waste and banana peels waste with bio-activator EM4 and <em>Aspergillus niger</em> (<em>An</em>) to increase the content of potassium (K) in organic fertilizer and study the response of plant growth of chillies and eggplant against organic fertilizer. Organic fertilizers were made from agricultural waste, such as bio ethanol solid waste, corn agricultural waste, and banana peels waste that still have organic content which was good for plant growth. Organic fertilizers were made by mixing bio ethanol solid waste, corn agricultural waste, and banana peels waste with a ratio (w/w)  of 1:2:3. After that, a mixture of EM4 and <em>An</em> with a ratio (v/v)  of 1:1, 2:3, 3:2, 1:3, 3:1 and without any bio-activator were added. Organic fertilizer produced in a rotary drum composter with air aeration 14 L · min<sup>–</sup><sup>1</sup> conducted for 15 d. The content of N, P and K on each variable of organic fertilizer will be analyzed. Then it was tested on chillies and eggplant. Furthermore, the quality and quantity of planting fruit on the plants of eggplant and chillies were measured. Based on the results of this study, it was concluded that organic fertilizer with the addition of EM4:<em>An</em> 2:3  (v/v) increased the content of K up to 0.43 %. In accordance with SNI standards: 19-7030-2004, all test variables met the standards of the levels of N, and P; all organic fertilizers met the standard C/N ratio unless at the variables EM4:<em>An</em> 1:3 (v/v) and without bio-activator. For chillies, variable with the addition of EM4:<em>An</em> 2:3 (v/v) has the greatest weight, namely 0.95 g. Another variable, EM4:<em>An</em> 3:2 (v/v) can produced the amount of fruit up to 300 %. Where at the addition of EM4:<em>An</em> 2:3 (v/v) can produced eggplant fruit that weighs 24.01 g per harvest.</p>

AbstractIn the present study, reactive red 198 (RR198) dye removal from aqueous solutions by adsorption using municipal solid waste (MSW) compost ash was investigated in batch mode. SEM, XRF, XRD, and BET/BJH analyses were used to characterize MSW compost ash. CNHS and organic matter content analyses showed a low percentage of carbon and organic matter to be incorporated in MSW compost ash. The design of adsorption experiments was performed by Box–Behnken design (BBD), and process variables were modeled and optimized using Box–Behnken design-response surface methodology (BBD-RSM) and genetic algorithm-artificial neural network (GA-ANN). BBD-RSM approach disclosed that a quadratic polynomial model fitted well to the experimental data (F-value = 94.596 and R2 = 0.9436), and ANN suggested a three-layer model with test-R2 = 0.9832, the structure of 4-8-1, and learning algorithm type of Levenberg–Marquardt backpropagation. The same optimization results were suggested by BBD-RSM and GA-ANN approaches so that the optimum conditions for RR198 absorption was observed at pH = 3, operating time = 80 min, RR198 = 20 mg L−1 and MSW compost ash dosage = 2 g L−1. The adsorption behavior was appropriately described by Freundlich isotherm, pseudo-second-order kinetic model. Further, the data were found to be better described with the nonlinear when compared to the linear form of these equations. Also, the thermodynamic study revealed the spontaneous and exothermic nature of the adsorption process. In relation to the reuse, a 12.1% reduction in the adsorption efficiency was seen after five successive cycles. The present study showed that MSW compost ash as an economical, reusable, and efficient adsorbent would be desirable for application in the adsorption process to dye wastewater treatment, and both BBD-RSM and GA-ANN approaches are highly potential methods in adsorption modeling and optimization study of the adsorption process. The present work also provides preliminary information, which is helpful for developing the adsorption process on an industrial scale.

Utilization of maize waste as the organic matter sources in agricultural land couldn’t be directly applied, caused by late decomposition prosess. An effort to accelerate of maize waste decomposting needed bioactivator. The research was conducted in green house and Bajeng Research Intallation from March to August 2015. The research was arranged in randomized block design using isolate bacteria and fungus just one or theier combining ie: three bacteria  (B7.1,E7.7and E7.11), three fungus (M7, O5, P7), and four bacteria-fungus combining(B7.1+O5, B7.1+M7, E7.7+P7, B7.1+E7.7+O5), EM4 and N,P,K fertilizer(200,45,60) ha-1as the check treatment. Just one isolate fertilized by 75 percent N,P,K while combine isolate fertilized by 50 percent N,P,K recommended. The results indicated that just one decomposer E7.7 produced high enouugh grain yield not siqnificantly different by N,P,K (200,45,60) and five other just one treatment (E7.11,B7.1,M7 and O5), however siqnificantly different with combining decomposer (B7.1+O5, E7.11+M7, E7.7+P7, B7.1+E7.7+O5 and EM4). This mean that using stalk plus leaf waste maize compost could be subtitution in organic fertilizer untill 25 percent. Meanwhile combining decomposer was good enough for composting stalk and leaf of maize waste ie. isolate B7.1+O5 and E7.7+P7 although not significntly different with the other combine isolate including EM4. Thise case related by applied 50 percent N,P,K inorganic recommended fertilizer did not sufficient to supporting maize nutrient.Key Words: Decomposer, Bacteria, Fungus, Composting,Maize waste
