Introduction. Semi-finished products require various additives that increase shelf life, improve sensory properties, or decrease raw material costs. Unfortunately, most additives improve neither nutrition nor biological value of the finished product. The present research featured precooked thin pancakes fortified with a chlorella concentrate. This microalgal supplement with scientific-based healthy properties is a unique project of Russian developers. The chlorella concentrate possesses a balanced amino acid composition, vitamins, major nutrient elements, and dietary minerals. Therefore, it can improve the nutrient and biological value of the pancakes. Study objects and methods. The research featured laboratory and industrial samples of precooked pancakes. 3%, 6%, and 10% of the milk were replaced with chlorella concentrate. The quantitative ratio of the components was determined empirically to obtain pancakes of the optimal quality. The batter-making and baking technologies were traditional. The mixing of milk and chlorella concentrate caused no protein aggregation. Results and discussion. The obtained batter was similar with the control sample in viscosity. The sensory properties did not deteriorate. As the proportion of the concentrate increased, the color of the batter changed from pale green to bright green. The sample with 10% of chlorella concentrate had a distinct algae smell. After the milk was replaced with the chlorella concentrate in the amount of 3%, 6%, and 10%, the amino acid composition demonstrated the following changes. The amount of lysine increased by 4.36%, 8.54%, and 14.72%, respectively. The amount of tryptophan increased by 5.46%, 10.75%, and 18.37, respectively. The amount of methionine + cystine increased by 4.04%, 7.94%, and 13.61%, respectively. The introduction of chlorella concentrate raised the content of certain minerals and vitamins, e.g. iron, vitamins of β-carotene, and vitamin C. Conclusions. Chlorella concentrate improved the production technology of flour-based foods. Therefore, it helps to expand the range of this group of precooked products while improving their biological and nutrition value.

<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>

Ethnographic examples of stone-tool makers in Australia and archaeological examples from three different areas in the western United States indicate that the availability of lithic raw materials is an important variable conditioning stone-tool production technology. Attributes of availability such as abundance and quality of lithic raw materials condition the production of formal- vs. informal-tool types. Poor-quality raw materials tend to be manufactured into informal-tool designs. High-quality lithic raw materials tend to be manufactured into formal-tool designs when such materials occur in low abundance. When high-quality materials occur in great abundance both formal- and informal-tool designs are manufactured. Other factors, such as residential mobility or sedentism, are found to be less-important determinates of lithic-production technology.

Based on mineralogical and technological investigations of the deposit 'Greda' important characteristics of bentonite clay were determined. Representative samples of the deposit were characterized with X-ray diffraction, low-temperature nitrogen adsorption, chemical analysis, differential thermal analysis and scanning electron microscopy. It was determined that the main mineral is montmorillonite and in subordinate quantities kaolinite, quartz and pyrite. The chemical composition generally shows high silica and alumina contents in all samples and small quantities of Fe3+, Ca2+ and Mg2+ cations. Based on technological and mineralogical research, bentonite from this deposit is a high-quality raw material for use in the ceramic industry.
