Cassava Production

Cassava is becoming increasingly important as an industrial raw material in China. However, an insufficient supply of cassava raw materials and the expanding demand for cassava in downstream-processing industries restricts the development of the cassava industry in China. This paper studies how to increase the scale of cassava planting and promoting cassava production efficiency using output-oriented Data Envelopment Analysis (DEA) modeling. Overall Technical Efficiency (OTE), Pure Technical Efficiency (PTE), and Scale Efficiencies (SE) of the cassava-production system in the major cassava production areas of China are calculated using Variable Returns to Scale (VRS). Results reveal that, in addition to the Guangdong province, the OTE of Guangxi, Hainan, Fujian, Yunnan, and Jiangxi is inefficient, with an OTE of less than 1. The largest cassava-planting province, Guangxi, has the lowest SE with 0.551. The PTE of Guangxi is close to the minimum with 0.344. The OTE of Guangxi is also the lowest among the five provinces with 0.190. This study also presents ways to improve production efficiency. Results reveal that Guangxi has a large ratio of transverse adjustment on average. In the Guangxi province, 1.70% of the service cost and 1.72% of the labor cost need to be eliminated to keep the current output scale. Meanwhile, service and labor costs need to be reduced by 3164.85 and 3209.92, respectively, to achieve the best production efficiency. Further industrialization and large-scale cassava cultivation, increased yield, and strengthened cooperation with the Association of South East Asian Nations (ASEAN) and Africa are suggested as policy options to improve the cassava system in China.

Corncob is usually disposed of directly as waste, creating problems in the environment, while it can be converted into valuable materials. This research aimed to evaluate the literature review on briquette production from agricultural waste (using non-binder and cold press with a binder) and the current works on techno-economic analysis, to propose an optimal design for the production of briquette from corncob waste, and to perform a techno-economic analysis based on the selected optimal processing method. The engineering perspective based on stoichiometry and mass balance showed the potential corncob briquette manufacture in both home and large scales due to the possible use of inexpensive and commercially available equipment and raw materials. The economic perspective [based on several economic evaluation factors (i.e., gross profit margin, payback period, break-even point, cumulative net present value, return of investment, internal rate return, and profitability index) under ideal and non-ideal conditions by considering internal (i.e., sales, raw materials, utilities, and variable cost) and external aspects (i.e., tax)] confirmed the prospective development of the project in the large-scale production with a lifetime of more than 18 years. The main issue in the project is the raw material (i.e. tapioca flour), giving the most impact on the project’s feasibility. Even in severe conditions, the project is feasible. The great endurance was also confirmed in the case of a higher tax rate. This study demonstrates the importance of producing corncob-based briquettes for improving the economic value and giving alternatives for problem solvers in the utilization of agricultural waste.

The article deals with the problems of mineral raw material losses of quality and quantity management in developing of large-scale complex-structure and composition deposits of solid minerals. It is shown that a very high degree of mining and geological conditions variability in time and space for the development of mining units is typical for such deposits. This significantly complicates the qualitative and quantitative operating losses setting and accounting of mineral raw materials during its extraction in the framework of existing general and industry regulatory documents. Conceptual principles for face-by-face operational setting of losses and impoverishment of minerals for the conditions of bulk mining of complex-structure deposits with the formation of gross mining flow with economically feasible and specified level of quality (the content of commercial and harmful components) are stated. These principles generally do not contradict effective instructions main provisions and are made to minimize the total operating losses during the processing of several mine sections (faces).

A frequently recurring problem in the extraction of mineral resources (especially heterogeneous mineral resources) is the rapid operative determination of the extracted quantity of raw material in a surface quarry. This paper deals with testing and analyzing the possibility of using unconventional methods such as digital close-range photogrammetry and terrestrial laser scanning in the process of determining the bulk density of raw material under in situ conditions. A model example of a heterogeneous deposit is the perlite deposit Lehôtka pod Brehmi (Slovakia). Classical laboratory methods for determining bulk density were used to verify the results of the in situ method of bulk density determination. Two large-scale samples (probes) with an approximate volume of 7 m3 and 9 m3 were realized in situ. 6 point samples (LITH) were taken for laboratory determination. By terrestrial laser scanning (TLS) measurement from 2 scanning stations, point clouds with approximately 163,000/143,000 points were obtained for each probe. For Structure-from-Motion (SfM) photogrammetry, 49/55 images were acquired for both probes, with final point clouds containing approximately 155,000/141,000 points. Subsequently, the bulk densities of the bulk samples were determined by the calculation from in situ measurements by TLS and SfM photogrammetry. Comparison of results of the field in situ measurements (1841 kg∙m−3) and laboratory measurements (1756 kg∙m−3) showed only a 4.5% difference in results between the two methods for determining the density of heterogeneous raw materials, confirming the accuracy of the used in situ methods. For the determination of the loosening coefficient, the material from both large-scale samples was transferred on a horizontal surface. Their volumes were determined by TLS. The loosening coefficient for the raw material of 1.38 was calculated from the resulting values.

Microbial oil is one of the ideal raw materials for biodiesel production because of its rapid reproduction and less influence by the climate and season variation. However, the high cost is one of the key issues that restricted its production in a large-scale. Lignocellulosic biomass, the cheap and renewable resource, might be the best raw material for microbial oil production by oleaginous microorganisms. Recent development on the microbial oil production from lignocellulosic biomass was summarized in this paper. Furthermore, the challenges and application potential of microbial oil were prospected.

The article justified the necessity of developing a strategy for the improvement of the sugar beet subcomplex of the region on the base of the determination of the close relationship between beet-growing farms, enterprises engaged in the delivery, processing and sale of manufactured products. According to the authors, the optimization of the raw material zone should include the principle of maximum loading of sugar mills, taking into account the raw materials produced in the region, optimizing transport costs for its delivery. The analysis of the sown area, productivity and gross yield of sugar beets gives us the idea that the region takes the tenth place among the largest producers of sugar beets. The yield and gross yield in 2019 in agricultural enterprises amounted to 459.6 centner / ha, 2231.9 thousand centner (an increase of 13.6% and 9.4% compared to the level of 2018).For P(F)E, the average increase is 40%, which corresponds to 481 centner / ha, 18.3 thousand tons. The average sugar content of beets during acceptance and processing ranges from 17.96 to 18.3%, the sugar yield is 15.63%, the sugar content in molasses is 1.68%, and the average daily productivity is 16.11 thousand ton / day, loss in production is 1.27%. The authors found that the production efficiency of the sugar beet industry is directly connected with the growth of labor productivity, the introduction of modern technologies, cost reduction, and thus, each farm has the opportunity to get additional profit. One of the main problems in the agricultural sector of the economy is the use of available resources to obtain the largest number of products. In our opinion, the production efficiency of sugar mills is closely interconnected with the constructed logistics routes for the transportation of raw materials with the exception of repeated shipments, the proportion of sugar beets in the sown area, and the reliability of suppliers. In our opinion, the efficiency of sugar mills production is in close connection with the built of the logistic routes for transportation of raw materials with the exception of repeated transportation, the specific weight of sugar beet in the structure of the sown area and the reliability ensuring of suppliers. The problem of the effective development of the sugar industry is relevant and priority in solving regional policies, the implementation of which will not only eliminate the emerging imbalances and reduce imports, but also support the domestic producer.

The Cost

With the addition of profits, the company can pay all costs that are sacrificed, so that the company's operational activities are guaranteed and can run well. The problems examined in this study are intended to find out how the comparison of recording costs using the full costing method and variable costing affects the net profit of PT Bhaskara Madya Jaya. Both of these methods simultaneously involve raw materials, direct labor costs and factory overhead costs. What distinguishes the full costing method using fixed factory overhead loads and variable, if the variable costing only adds to the variable overhead load. Production costs that are not included in the raw material and direct labor costs are the overhead of the manufacturing plant itself. Descriptive method with a quantitative approach is the model of this research. With the use of saturated sampling. Documentation is a data collection technique that researchers use. The results of the study and details obtained by comparing the full costing method and variable costing. In detailing the cost of production, the full costing method produced a greater than the costing variable, this is due to the full costing method adding all the elements of costs, variable costs or fixed costs . Then from the results of the breakdown of net income, using the full costing method, the nominal profit is found to be far less than using the variable costing method.

By combining blockchain with physical tracking technologies, raw materials can potentially be traced throughout their global supply chains. Physical tracking technologies enable observing how raw materials move within the physical world, whereas blockchain translates these events into the digital world with an immutable record. This paper presents a taxonomy of different physical tracking technologies and examines if and how the combination of these technologies render raw material supply chains more transparent. Although academic literature highlights the theoretical benefits of combining these transformative technologies, large scale projects are still in their early stages. Following a brief literature review, this paper leverages an empirical approach to classify different tracking technologies, their fields of application and limitations, as well as how these technologies can enable supply chain transparency. Obviously, there is no single technology that can fulfil all requirements along complex supply chains. However, the relevant combination of respective technologies can help bridge gaps by increasing transparency within supply chains.
