Characteristic and boactive potential of brewed Sargassum sp. with the additional bay leaf (Syzygium polyanthum)

Abstract Brewed Sargassum sp. is a product of dried seaweed that is packaged in tea bags and then brewed. The natural fishy odor from seaweed itself makes consumer acceptance of this brewed drink relatively low. The purpose of this study was to determine the effect of the addition of bay leaves (Syzygium polyanthum) and to determine consumer acceptance using hedonic test for Sargassum sp. Samples were obtained from UD Seaweed Mandiri, Wonosari, Yogyakarta. The research method used is experimental laboratories with a completely randomized design (CRD) model. The treatment given was in the form of different concentrations of bay leaves, namely 0%, 10%, 20%, and 30%. Parameters observed were water content, ash content, image processing, hedonic, phytochemical, antioxidant activity, and bioactive components. Parametric data were analyzed using analysis of variance ANOVA and Honest Significant Difference to determine differences between treatments, while non-parametric testing included hedonic tests consisting of aroma and taste tests. The results showed that the different concentrations of bay leaves gave a significantly different effect on the hedonic parameters. Brewed Sargassum sp. with a concentration of 30% had the highest score on the hedonic test, namely 7.71 < µ < 8.11 which was included as favored by the panelists. The addition of bay leaves with a concentration of 30% resulted in an IC50 value of 13.6251 ppm. Phytochemical screening which was carried out qualitatively showed positive results for the parameters of flavonoids, phenols, tannins, and saponins. The total flavonoid content of 30% concentration is 302,333 mg QE/g and produces six compounds with bioactive components. The highest compound is pentane at 69.12%. Based on the test of bioactive components in the brewed Sargassum sp. there is a pentane compound which has the potential as an antimicrobial and anti-inflammatory.

Application of ozone combined with the chilling system on preserving fresh fish has obviously brought about more advantages. This study observed the application of an ozone-slurry ice combined system for maintaining the freshness of two different fishes during storage. The fishes used were red tilapia (Oreochromis niloticus) and short-bodied mackerel (Scomberomorus rastrelliger), using ozone and slurry ice. The experimental design used was factorial using a completely randomized design employed with an ozone concentration of 0 ppm and 3.5 ppm with storage times of 0, 4, 8, 12, and 16 days. The parameters observed included: peroxide value (PV), total volatile base nitrogen (TVBN), total viable count (TVC), and a sensory test. The parametric data were analyzed using ANOVA and followed by least significant difference (LSD), whereas the non-parametric data were analyzed using the Kruskal Wallis test followed by multiple comparison tests. Ozone and slurry ice treatment of different concentrations had a significant (p<0.05) effect on the TVBN, the PV, and the TVC. The interaction of ozone and slurry ice provided no significant difference (p>0.05) in both samples.A sensory evaluation in both samples showed good correlation with TVC. This study showed that ozone and slurry ice could maintain the samples freshness during storage.

A factorial experiment was conducted with a completely randomized design to evaluate the effects of planting date and density on calendula herbs and peppermint. It had 3 replicates and was done in Khosroshahr research farm, Tabriz in 2006. Under studied factors were: 3 planting dates (10 May, 25 May and 10 June) in 4 densities (25, 35, 45, 55) of the plant in square meters. The results of variance a nalysis showed that there was 1% probability significant difference between the effects of planting date and bush density on the leave number, bush height and the bush dry weight. But the mutual effect of the plant date in mentioned traits density was insignificant. Regarding the traits mean comparison, the total maximum dry weight was about the 55 bush density in mm. Also, the bush high density in mm causes the bush growth and its mass reduction. When there is the density grain, the flower number will increase due to bush grain in surface unit. Overall, we can conclude that 10 June planting and 45 bush density in mm is the most suitable items and results in favored production with high essence for these crops.

ABSTRACT This study aimed to understand the influence of sowing depth and the amount of sugarcane straw on the emergence of weed species Luffa aegyptiaca Miller (Cucurbitaceae); Mucuna aterrima Piper & Tracy (Fabaceae - Leguminosae) and Ricinus communis (Euphorbiaceae). A completely randomized design with a 5 x 4 x 3 factorial layout with four replications was used, at five sowing depths (0, 2, 4, 8 and 10 cm), four different amounts of sugarcane straw (0, 5, 10 and 15 t ha-1) and three different evaluation periods (7, 14 and 21 days after sowing). After sowing, different amounts of sugarcane straw (0, 5, 10 and 15 t ha-1) were deposited on soil. Seedling emergence was analyzed at 7, 14 and 21 days after sowing, counting the number of seedlings that had emerged. At the end of the trial, weed height (cm), leaf area (cm2) and shoot dry mass (g) were measured. In relation to emergence ability, studied species presented different responses according to sowing depth and to the amount of sugarcane straw deposited on the soil. For the L.aegyptiacaand M.aterrima, no significant difference was observed in the interaction between depth and sugarcane straw, showing the adaptation of these species to no-burn sugarcane system. For R.communis, seeds placed at 0 cm of sugar cane straw depth were observed to favor the emergence of seedlings.

Apple fruits are subjected to different loading damage from harvesting to supermarket shelf. Bruising has been attracted many researchers as one of the most important damage criteria. In this research, the effects of some factors such as counter-face material, drop height and linear velocity of apples (conveyor speed) were investigated. Influence of these factors on bruising of ?Golab-Kohanz? variety was analyzed by a Completely Randomized Design (CRD) with factorial test at three levels of drop height (10, 20 and 30 cm), conveyor speed (0.05, 0.1 and 0.15 ms- 1) and four counter-face materials (wood, steel, plastic and cardboard). Tests were conducted at three replications with 108 treatments. Analysis of variance results showed that the effects of drop height and counter-face material on bruising area at 1% level was significant while bruising volume only affected by contact surface material (P<0.01). Mean comparison test indicated that there was no significant difference among levels of conveyor speed on the area and volume bruising. Also, there was no significant difference among levels of drop height on volume bruising while it was significant on the area bruising. Steel and wooden material had no significant effect on the area and volume bruising but their differences with plastic and cardboard were significant. Therefore, drop height and counter-face material must be considered in designing the apple processing systems.
