Environmentally Friendly Production

In our study, vegetative characteristics of 39 apple cultivars were evaluated in environmentally friendly production systems. Numbers of the branches of the central leader in different high zones were shown. According to our results, number of the branches of the axis was probably larger in the integrated production system, compared to the organic one, which is related to the conditional status of the trees. Based on our experiences training and maintaining canopies in integrated system was easier, as relative more extensive canopies were needed in organic farming.

<p>Plastic is a packaging materials that are widely used but has an adverse impact on the environment because it is difficult to degrade in nature. Production technology of biodegradable plastics from natural resources that have characteristic environmentally friendly has developed. Starch-based biodegradable plastic is a widely developed type because the production process is simple and the raw materials more readily available. The starch of cassava and sago has potential as a raw material of biodegradable plastic because of the availability and its characteristic. Also, to make starch as the main ingredient, plasticizers and structural strengthening materials are required to produce biodegradable plastic with excellent characteristics. The production stages of biodegradable plastics include mixing, heating, and casting. The starch-based biodegradable plastic that can apply to an environmentally friendly packaging material has an excellent opportunity developed in Indonesia.</p><p>Keywords: Starch, sago, cassava, biodegradable plastics, production technology</p><p> </p><p><strong>Abstrak</strong></p><p>Plastik merupakan bahan pengemas yang banyak digunakan namun berdampak buruk bagi lingkungan karena sulit terdegradasi di alam. Teknologi produksi plastik biodegradable atau bioplastik yang dibuat dari bahan alami dan ramah lingkungan sudah mulai dikembangkan. Plastik biodegradable berbahan dasar pati relatif lebih mudah diproduksi dan bahan baku mudah diperoleh. Pati ubi kayu dan sagu memiliki potensi sebagai bahan baku plastik biodegradable ditinjau dari ketersediaan dan karakteristiknya. Selain pati sebagai bahan utama, diperlukan pula plastisizer atau bahan pemlastis dan bahan penguat struktur untuk menghasilkan plastik biodegradable dengan karakteristik yang baik. Tahapan produksinya meliputi pencampuran, pemanasan, dan pencetakan. Plastik biodegradable berbahan dasar pati dapat digunakan sebagai bahan pengemas yang ramah lingkungan dan berpeluang besar dikembangkan.</p><p>Kata kunci: Pati, sagu, ubi kayu, bioplastik, teknologi produksi</p>

<p>Nowadays the organic compost is very important for farmers because of its environmentally friendly character. However, the production technology of organic compost is not well-known yet for the farmers. This study aimed to utilize corn by-product compost as fertilizer for plants growth. Composting process was accelerated by addition of composting organism called as effective microorganism (EM4) and <em>Azotobacter</em>. Their composition were EM4:<em>Azotobacter</em> 1:1 ; 1:3, EM4 alone, <em>Azotobacter</em> alone and without addition of composting microorganism. The composting process was conducted in a composter for 15 d and mixed three times per day. The process should be carried out under controlled aerobic conditions. The observed parameters were carbon (C), nitrogen (N), phosphor (P), and potassium (K) content. The parameters was measured before and after composting process. The resulted compost were applied to the growing corns, chilis, and tomatoes as fertilizer. The result showed that the best compost was obtained on 3:1 composition of EM4 : <em>Azotobacter</em>. This composition was able to reduce 0.74 % carbon content, and increase 151.46 %, 147.9 %, and 238.42 % of N, P, K content respectively. Moreover this particular compost was able to bring 3.75 mm corn stem and 1.0 mm corn leaf growth per day, lead to harvesting of  two tomatoes and eight chilie</p>

The paper considers the theory of energy production cycles. It indicates its relevance and the possibility of successful application for the analysis of the territorial structure and assessment of the prospects for modernization of the economy. At the same time, questions are raised about the inconsistency of this concept with modern market conditions. An attempt is made to rethink the theory of energy production cycles, on the basis of which the concept «coal cycle of productions» is formulated and the author’s generalized scheme of this cycle is given. Next, the research compares a general scheme of the coal production cycle with the production cycle actually formed around Kuznetsk coals. On the basis of this comparison, the degree of completeness and the reserves for further modernization of this cycle of production were revealed. Among the possible directions of coal use, the most promising for introduction in the Kuzbass are indicated, namely: coal semi-coking, gasification (including underground coal) and preparation of water-coal fuel. The research has revealed some positive effects from this complication of the existing coal production cycle in the Kuzbass.
