The use of papaya latex formulated with nitrogen supplementation and minerals in the form of multinutrition blocks that can pass through the rumen is expected to improve nutritional quality and feed digestibility. This study aims to evaluate the effectiveness of the use of fermented rice straw, papaya fruit latex and blood clamshell flour as a main raw material in the manufacture of multinutrition blocks plus herbal anthelmintic medicine (papaya fruit latex) on physical quality (texture, color, aroma, hardness), chemical quality (proximate composition and mineral content of Ca, P, Mg, Cu, Zn). Microbiological tests were carried out on total bacteria, Salmonella and Escherichia coli. The research design used was a completely randomized design with 4 treatment levels of papaya fruit administration and 4 replications. Data is processed statistically using ANOVA. The results of organoleptic physical quality analysis showed significant differences in the texture of the product given the highest papaya latex (0.007ml / kg). Chemical analysis of the product showed a quantitative increase in protein, although statistically the treatment did not show any significant differences. The results of the analysis of the microbiological quality of the product quantitatively showed that the resulting multinutrition block herbs were not contaminated with negative bacteria. It was concluded that multinutrition block herbs can be given to livestock as supplementary feed.

The Relationship

One of the remarkable effects of the economical and social development is the changing of the eating habits, first of all increasing consumption of deep-frozen products. The spreading of the sweet corn under these vegetables is characteristic.The parameters exerting influence on the quality of the deepfrozen sweetcorn is classed in 3 categories:• Physical quality: foreign matter, clumps, blemished corn, broken kernel, miscut, pulled kernel.• Organoleptical features: taste, colour, texture, and sweetness.• Microbiological features: TVC, mould, yeast.The moisture content of the raw material influences the organoleptical features to the highest degree.We take continuously samples from the raw material arriving in to the factory to determinate moisture content, and from the product to specify the organoleptical features.Based on the data of 2002 we can make the following findings:The colour of the deepfrozen sweetcorn is less influenced by the moisture content. The taste is between 69% and 72% the most optimal, but over 72% get worse, more „milky”, water-tasted because of the underdevelopment of sweetcorn. The texture continuously becomes better with the increasing of moisture content. Under 67% of water the class „C” is typical, which means a taste with weak charasteric, a bit scathing or bitter, and texture with rubbery inner part and hard pericarpia. The decadence of taste is caused by converting a great part of sugar into starch.The correlation between moisture and quality is varying by varieties; different varieties have their best quality by different moisture content. By our investigations the best harvest time is at the 69-72% moisture content. At this point are the organoleptical features the most optimal, and the grower has not the loss of yield caused by early harvesting.

The aims of this study were to evaluate the quality of feedstuff as concentrate feed raw material, the quality of feed concentrate, and customer satisfaction toward concentrate quality produced by the cooperative. The parameters observed were nutrient contents (moisture, ash, crude protein, crude fat, and crude fibre) and physical quality (density, bulk density, and compacted bulk density). Farmer satisfaction was measured using customer satisfaction index (CSI) and gap analysis. The data obtained consisted of primary data (nutrient content of feedstuff and physical quality) and secondary data (nutrient content of concentrates) that were then analysed descriptively. Total respondents in the satisfaction analysis were 100 farmers. The results of this study indicated that feedstuff nutrient content varied, even though corn gluten feed (CGF) was in the range of Indonesian National Standards (SNI). The highest density and bulk density were limestone, and the highest compacted bulk density was salt, while the lowest physical quality was coffee chaff. Nutrient content of concentrate complied with SNI except for crude fat content. Meanwhile, the physical quality of the concentrate was still within the normal range. Farmer satisfaction was in the satisfied category with the highest gap values absence of foreign objects. Key words:        concentrate feed, CSI, farmer satisfaction, feedstuff, quality

Repetitive implementation of material value conservation (MVC) in plastic packaging may lead to good quality plastic waste and high acceptance for secondary recycling. This makes the obtained recycled plastic pellets has good quality and can be used as an alternative raw material for new products. However, treatments and processing in the recycling processes can lead to the degradation of material properties and disrupt the recycled plastics life cycle to be used for new products with high specifications. Recycled plastics are certainly cheaper than virgin plastics, but they have low properties, contaminated, and are only used for low-value products. Therefore, a solution is needed for this problem. This study proposed mixing recycled and virgin plastic pellets to improve recycled plastics whose optical properties have been subjected to quality degradation. A series of tests were carried out on specimens and tested according to the American Society for Testing and Materials (ASTM) method. The optical properties tested were transparency, gloss, and colour. This study revealed that optical properties had an increasing trend along with the large number of virgin plastic pellets added to the blends. The optimal composition was found in the 50:50 composition of virgin-recycled plastic pellets to the 70:30 composition of virgin-recycled plastic pellets. These findings can be useful in improving the optical properties of recycled plastics. In addition, the widespread implementation of MVC can improve the quality of plastic waste and strengthen its acceptance for secondary recycling.

Abstract The aim of the study was to assess the usefulness of hybrid drying methods (convective-microwave and convective-microwave-ultrasound) for sour cherry fruit preservation compared to convective drying. As the raw material, three sour cherry cultivars varying in quality characteristics (‘Łutówka’, ‘Debreceni Bötermo’, ‘Nefris’) were used. Before drying, fruits were subjected to osmotic treatment. Three different drying methods were examined: 1) convective (C), 2) hybrid with microwaves (C-MV) and 3) hybrid with microwaves and ultrasound (C-MV-US). As the quality indicators of the investigated processes, the changes in chemical composition, including alterations in the main groups of bioactive components, as well as in the antioxidant potential were monitored at each production stage. It was found that, when compared to convective drying, the use of the hybrid techniques allowed the drying time to be reduced from 9 to just 3 hours. Furthermore, employing hybrid drying eliminated the problems associated with the dehydration barrier observed during convective drying of the cultivar ‘Debreceni Bötermo’. Regrettably, although the ultrasound used as the additional source of energy in the hybrid method slightly improved water evaporation, in general no significant effect on the retention of phenolic compounds was found. Irrespectively of the drying method, the effect of the cultivar proved to be crucial to the quality of the final product. Under the same processing conditions, ‘Nefris’ turned out to be the most promising cultivar for producing ready-to-eat fruit snacks of high nutritional value.

This study aimed to determine the effect of raw materials Legetan in the form of fresh and hay on the physical quality of pellets. Legetan (Synedrella nodiflora) was used as main ingredient, in the form of fresh and hay. The research method used a Randomized Completely Block Design (RCBD). Then, if there was a significant difference, it will be analyzed further using Duncan multiple range test (DMRT). The treatments consisted of P1 = 10% rice bran + 90% fresh Legetan; P2 = 20% rice bran + 80% fresh Legetan; P3 = 10% rice bran + 90% hay Legetan; P4 = 20% rice bran + 80% hay Legetan. The variables measured were rendement, color, texture, and price. The results showed that the utilization of Legetan forage as raw material, both hay and fresh with the proportions of rice bran either 10:90 or 20:80, had no significant effect on the physical quality of Legetan forage pellets. However, the higher the portions of Legetan forage in the forage pellets, the more affordable the pellet price will be.
