Abstract

Making preparations for observing cells or tissues in practicum activities requires dyes. In cell biology practicum, especially observation of plant tissue in the Department of Biology Education, FKIP, Ambon University of Darussalam, it is still very limited, because it does not have chemical dyes for making preserved preparations. This is because chemical dyes are quite expensive, unsafe, and will spoil if stored for a long time, so it is very important to make natural dyes as a substitute for synthetic dyes so that the preserved preparations produced are safer, more affordable, and can be used for a long time. which is old. Sources of natural dyes are obtained from plant parts, for example: roots, bark, leaves, fruit, wood, seeds, and flowers. Turmeric (Curcuma domestica Val.) is a natural dye that can be used, because it is relatively cheap, easy to find, non-carcinogenic, and biodegradable. The active pigments in turmeric which can color plant tissue and give it a yellow color are curcuminoids. The aim of this research was to study the utilization of turmeric extract (Curcuma domestica Val.) as a natural dye for preparing preserved preparations of plant tissues in cell biology practicum. This type of research is experimental research, which has several stages of research including: observation, preparation, research implementation, and analysis stage. At the data analysis stage, a qualitative descriptive method was used to determine the quality of the preserved preparations. The quality of the preparations in this study was expressed by the percentage of eligibility of ≥ 62.5% or feasible criteria. The results showed that the average percentage of the quality of the preparations that had been validated was 66.96% and 67.85% with proper criteria. This shows that the preserved preparations made are suitable for observing plant tissues in cell biology labs.

Abstract

Tetragonula laeviceps belongs to a class of stingless bees that can produce honey. Tetragonula laeviceps honey contains compounds that are antibacterial. The purpose of this study was to determine the effect of stingless bee honey on the growth of the bacteria Salmonella typhi that causes typhus, Escherichia coli causes diarrhea, and Staphylococcus aureus causes skin infections, and can contribute to Eubacteria material in class X SMA. This research was conducted at the Biology Education Laboratory, State Islamic University Raden Fatah Palembang. The method used was a completely randomized design (CRD), an experimental study with 5 repetitions divided into 4 treatments (3%, 5%, 7%, and 9%), and 1% tetracycline as positive control with distilled water as diluent. The results of this study were that the 9% concentration treatment showed the greatest effect. The size of the inhibition zone of 9% honey Tetragonula laeviceps for Salmonella typhi was 1.23 mm, Escherichia coli was 3.68 mm, and Staphylococcus aureus was 3.09 mm. The resulting inhibition zone has a weak category because it is < 5 mm. Based on the analysis of the calculations carried out by the One Way ANOVA test for each bacteria, which has a value of 0.00 <0.05, which means that each treatment has a significant effect, then proceed with the Duncan Significant Distance Difference (BJND) test, where the DMRT results for honey bee treatment stingless was smaller than the mean diameter of the positive control, which meant that each treatment of stingless bee honey was very significantly different from the positive control. This shows that Tetragonula laeviceps honey has the effectiveness of inhibiting the growth of Salmonella typhi, Escherichia coli, and Staphylococcus aureus.

Abstract

Fish paste is a local product which is a source of income for coastal communities in Situbondo Regency. Production of fish paste is still dominated by household business scale. In addition to paying attention to chemical and microbiological quality, it is necessary to pay attention to sensory quality to meet the quality and food safety requirementsof the paste. Even, organoleptic quality greatly determines consumer acceptance to buy products. This study aims to determine consumer acceptance of the organoleptic quality of four types of fish paste products produced by producers A, B, C, and D in Situbondo Regency. Testing on consumer acceptance is carried out by sensory testing using the hedonic test method. The sensory parameters tested included: color, aroma, taste, aftertaste, and overall acceptance of the paste. There are 9 hedonic scales used in this test, namely very dislike (1), really dislike (2), dislike (3), rather dislike (4), neutral (5), rather like (6), likes (7), likes very much (8), and likes very extremely (9). The numerical scale (1-9) is processed using ANOVA and Duncan's test. The results showed that the organoleptic quality of the four types of fish paste was rated somewhat neutral (5) to rather like (6). Among the four products, the fish paste D (5.84) and B (5.75) that are most accepted by consumers with characteristics: dark brown paste, the aroma of spices and fish are smelt, the savory taste is felt, the fishy aftertaste doesn't linger in the mouth, and the texture is homogeneous-elastic-soft. While the petis made by producer A got a preference value of 4.92 (ordinary) and the petis made by producer B with a preference value of 5.17 (ordinary).
