This study uses a Completely Randomized Design experimental method (CRD) consisting of three treatments with a range of 5 days, 10 days and 15 days, with each treatment uses three insect specimens. The treatments in this study were; P1 (200 mg ash + 200 ml distilled water), P2 (70% alcohol), and P0 (control). To observe the changes in texture, aroma and color in the inspect specimens, 50 panelists were engaged, who were aged between 17-30 years, that were not color blind and/or reporting any ill health at the time of sampling. Panelists observed the specimens for texture, aroma and color.  Resulting data was analyzed using t test, frequency tabulation, histogram data and normality test. The texture testing treatments yielded tcount = 0.02521 (p 0.05) showing no significance between the coconut midrib ash and alcohol preserved samples, with the Ho accepted, so there is no difference in the texture of insect specimens preserved in either coconut midrib ash or alcohol. The aroma test resulted in tcount = 0.00908 (p 0.05) showing again there was no significant difference between insect specimens preserved in coconut midrib ash and alcohol. Thus, the Ho can be accepted, with no difference in the aroma of insect specimens preserved in coconut midrib ash or with alcohol. The color test resulted in a tcount = 0.05635 (p 0.05), giving a insignificant result between insect specimens preserved in coconut midrib ash or alcohol. Thus, the Ho can be accepted, and there is no difference in color of insect specimens preserved with coconut midrib ash or those preserved with alcohol. From the overall results and analysis, we can conclude there is no difference in the quality insect specimens preserved either by coconut midrib ash and alcohol for a maximum 15 days. Penelitian ini menggunakan metode eksperimen rancangan acak lengkap (RAL) yang terdiri dari tiga perlakuan dengan kisaran lama waktu 5 hari, 10 hari, dan 15 hari.

High Level

Beef has a high level of toughness that is not liked by consumers. The solution to increasing beef tenderness is to soften the beef. One method for tendering the beef is by marinating using local ingredients that are easily available, abundant, and inexpensive, namely pineapple. Pineapple peel is waste from pineapple that has not been utilized and is usually discarded. In pineapple peel, there is a bromelain enzyme thought to be able to hydrolyse protein so that it can tender beef. The purpose of this study was to find out the organoleptic properties of beef using the marination with various pineapple peel juice concentrations (Ananas comosus L. Merr) namely 0%, 10%, 20%, and 30%. This study used an experimental method with a Completely Randomized Design consisting of 4 treatments and 4 replications. The parameters in this study were organoleptic properties namely colour, aroma, texture, tenderness, and taste. Results of the study showed that beef marination with various pineapple peel juice concentrations had a significant difference (P<0.05) on taste, texture, and tenderness of beef but had no significant difference in colour and aroma (P>0.05)

Rice Seeds

Aiming at verifying effects of priming on germination and emergence of seeds subjected to low temperatures, rice seeds (cv. IRGA 418) were primed into a KNO3 solution during 24, 48, and 72 h, at 20 °C; and into distilled water, for 24 h (control). Germination (G), first count of germination (FCG), and germination speed index (GSI) were the parameters assessed under temperatures of 17 °C, 20 °C and 25 °C. Besides, field emergence (FE), and emergence speed index (ESI) were also assessed under field conditions. A completely randomized design was used with treatments arranged in 4 x 3 factorial (treatments x temperatures) in all experiments. None statistically significant difference was found for seed germination within the 24 h imbibition period, under any of temperatures assessed; although after 48 and 72 h, at 17 °C, this variable has decreased. When seeds were imbibed in KNO3, during 48 and 72 h, the FCG and GSI were decreased, as compared to 24 h imbibition period, and for control treatment, at 17 °C and 25 ºC. After 24 h imbibition, the FE has not differed statistically from control treatment; as occurred for periods of 24 and 48 h imbibition for the ESI parameter. Priming in KNO3 does not cause beneficial effect on seed germination or on seedling emergence of rice.

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.
