Management of post-production wood waste in the aspect of circular economy. Sustainable resource management involves turning waste into resources. The estimation of various waste streams and their potential use as secondary raw materials underlies the circular economy. The management of wood waste in terms of the Circular Economy should assume material use of this waste before energy use. One of the possibilities of material management of this waste is the use of biological treatment through composting. Input materials for the composting process should have technological and physical-chemical characteristics, respectively. The aim of this study was to characterize the wood raw material (wood waste as a by-product) and qualify it for the composting process on the basis of its composition. Based on the literature research, it was found that there is possibility of using these wastes for management through biological disposal. The obtained composts from wood waste can be used as a raw material to supply the soil with humic substances and mineral compounds.

The study aimed to assess the most efficient solution of raw material management in selected biogas plants into the concept of circular economy and evaluate the most efficient solution of raw material management in selected biogas plants due to the quality and quantity of the feed and the final product obtained, which is biogas, as well at the closed circulation (circular economy). The study evaluated two agricultural biogas plants on a real scale and one at the sewage treatment plant (in real scale) in northeastern Poland. A year-long study showed that in technical terms, the best work efficiency is achieved by agricultural biogas plants processing: silage, manure, apple pomace, potato pulp (biogas plant No. 1), followed by biogas plant No. 3 processing chicken manure, decoction, cattle manure, poultry slaughterhouse waste (sewage sludge, flotate, feathers), and finally, the lowest efficiency biogas plant was No. 2, the sewage treatment plant, which stabilized sewage sludge in the methane fermentation process. Moreover, based on the results, it was found that agricultural biogas gives the best efficiency in energy production from 1 ton of feed.

Material Efficiency

In this paper, the effect of material management on productivity level of fast moving consumer products enterprises in Nigeria was assessed. The survey design was employed and questionnaire was the major instrument of data collection designed via two material management dimensions (raw materials and work-in- progress) and productivity dimensions (material efficiency and yield). Questionnaire were administered to three hundred and seven (307) respondents and data obtained were analyzed using Canonical correlation. Results of canonical correlation analysis revealed that the combination of material efficiency and yield (productivity proxies) had a statistically significant relationship on sets of material management being measured by raw material and work-in-progress. The study concludes that improvement in material management will increase the productivity of FMCG companies in Nigeria. Given the results of the study, improvements in material management is needed such that material requisition and conversion units should ensure that required materials for production of goods are those put into the production process in order to realize efficiency of production and superior yield of finished goods by fast moving consumer products organizations. In addition, fast moving products companies should ensure maintenance of optimum level of material resources in its store room and reduce unhealthy practice in material usage that are pivotal to reducing productivity.

Perencanaan produksi merupakan hal yang sangat penting bagi perusahaan, karena dalam proses perencanaan ini akan menentukan jumlah produk yang akan di produksi. Dalam penelitian ini, permasalahan yang terjadi disebabkan karena perusahaan tidak memprediksi fluktuasi permintaan dengan tepat sehingga banyak produk yang dihasilkan mengalami penumpukan.Penumpukan yang terjadi merupakan kerugian karena penggunaan bahan baku yang berlebihan untuk produk yang tidakterjual. Oleh karena itu, pengelolaan bahan baku harus dilakukan dengan tepat. Dalam penelitian ini, metode yang digunakan untuk memprediksi permintaan adalah Winter dan goal programming untuk optimasi bahan baku. Metode Goal programming digunakan karena terdapat lebih dari satu fungsi tujuan dalam permasalahan.Penggunaan metode winter ini menghasilkan jumlah permintaan dengan tingkat akurasi 90% dari roti bandung 4.040 pcs, roti meises 4.149 pcs, roti tawar kupas 3.315 pcs, roti selai 4.095 pcs. Hasil yang diproleh diharapkan mampu memprediksi permintaan secara tepat sehingga penggunaan bahan baku dapat dioptimalkan menggunakan goal programming.   Production planning is a very important key for a company, because production planner will decide the amount of products that will be produced.In this study,the problem occurred is that the company did not predict the exact demand fluctuation therefore there are many amount of products cumulated.This cumulation is also because the used of excessive raw materials for unsold products. Therefore the exact raw material management should be applied.In this study,the method that used to predicting the demand is Winter and Goal programming for the raw material optimization.Goal Programming method is used because there are more than one(fungsi tujuan)in one case.The result of Winter method is the amount of demand with 90% level of accuracy from roti bandung is 4040 pcs,roti meises is 4149 pcs,roti tawar kupas is 3315 pcs,and roti selai is 4095 pcs.The results is expected can be predicted the exact demand therefore the used of raw materials could be optimized using goal programming method.

The craft industry is growing rapidly in Bali as a support for the tourism sector, moreover Bali is a world tourist destination. One of them is silver craft, which has now developed as a fashion value product. To create a competitive product, which has quality, quality and uniqueness, of course management material (in this case silver as raw material) needs to be considered. The purpose of this study is to analyze the influence of innovation and competitive advantage on business performance, as well as the role of material management on the influence of competitive advantage on the business performance of silver craft SMEs in the Province of Bali. The population in the study was silver craft SMEs in Gianyar Regency, which is the center of the silver industry in Indonesia. The sample size is determined by the formula Isaac and Michael, so that a sample of 146 respondents was obtained. Data was collected through questionnaires and independent interviews. Furthermore, the data were analyzed using the SEM-PLS approach. The results of data analysis show that competitive advantage has a positive and significant effect on business performance, while material management directly or as a moderator turns out to have no significant effect on business performance. It is recommended that silver craftsmen do material management in a simple but careful manner, and focus more on forming product competitiveness.
