Abstract

The Hibiscus genus is a member of the Malvaceae family with striking flowers of various colors. Hibiscus is a genus that is easy to find in Indonesia because it is usually used as an ornamental plant, hedge plant, cut flower, medicinal plant, or tea for drinking. This research was conducted to know the phenetic relationship of 6 species of Hibiscus based on morphological characters. The research was conducted by observing 57 morphological characteristics of 6 species of Hibiscus, then UPGMA (Unweighted Pair Group Method with Arithmatic Mean) analysis using MEGA 11 software. The samples in this study were six species belonging to the Hibiscus genus, namely Hibiscus rosa-sinensis L., Hibiscus tiliaceus L., Hibiscus macrophyllus (Blume) Okenlada, Hibiscus mutabilis L., Hibiscus sabdariffa L., and Hibiscus acetosella Welw. ex Hiern. The results showed that 6 species of Hibiscus formed 3 clusters based on differences in habitus and stem diameter. H. tiliaceus and H. macrophyllus formed cluster one, H. acetosella and H. sabdariffa formed cluster two, while H. rosa-sinensis and H. mutabilis formed cluster three. The closest phenetic relationship is between H. acetosella and H. sabdariffa, with a dissimilarity index of 0.140 or 86% similarity. The furthest phenetic relationship was in H. rosa-sinensis and H. macrophyllus with a dissimilarity index of 0.737 or a similarity percentage of 26.3%.

Abstract

Bitter melon (Momordica charantia L.) is a vine, elongated, and has fruit that is small oval in color and has rather fine nodules, with a characteristic very bitter taste found in the fruit. The purpose of this study was to determine the quality of bitter melon which is used as a food ingredient and to increase the value of developing food products in society and the modern market. The method used in this research is a descriptive survey method. Based on the results of research conducted bitter gourd contains lots of vitamins and very good properties. The existence of bitter gourd is very easy to cultivate so that it can be used as food that can be marketed in the community. Therefore, it can be easier to introduce bitter melon to the public by managing and knowing the marketing strategy for bitter melon, so that bitter melon can develop into the international market. Given the low and limited use of bitter gourd, it is therefore necessary to develop food products made from bitter gourd to increase its value and use which is none other than the nutritional content of bitter gourd. One way to take advantage of the value of its content is to process it into bitter melon chips. Chips are snacks that have a high shelf life, good taste, and many variations to meet consumer tastes.

Abstract

Measurement of morphological characteristics is needed to understand buffalo's conformation, productivity and reproduction. This study aims to describe the morphological characteristics of buffalo taken from the West Nusa Tenggara region and to carry out phenetic analysis based on the results of morphological character measurements. This study was exploratory with 16 individual buffalo as subjects taken purposively from two different populations, namely West Sumbawa and West Lombok Regencies, West Nusa Tenggara. The morphological characters measured included leg length, hip width and head width. Morphological character data were analyzed descriptively and non-parametrically using the Mann-Whitney test. In contrast,the phenetic analysis used the Unweighted Pair Group Mean Average (UPGMA) method supplemented by Principle Component Analysis (PCA). The measurement results showed variations in the morphology of the buffalo (Bubalus bubalis) in West Sumbawa and West Lombok Regencies. The character of leg length was significantly different in both populations (Sig <.05). In contrast, the other two characters, namely head width and hip height, were not significantly different (Sig >.05). Furthermore, the phenetic analysis showed that the relationship between the two populations of buffalo was significantly different, which was strengthened through PCA analysis which revealed that there was no genetic mixing between the buffalo populations.

Abstract

In cell material, many concepts are abstract and can cause students to experience difficulties in understanding them. Every concept in biology learning is interconnected so that every concept that is built can influence the formation of the next concept. However, often students' initial concepts are misconceptions, namely the concepts possessed by students conflict with the concepts raised by experts. A good learning experience is needed so that students can understand the concept correctly. One learning model that provides a learning experience to discover and understand concepts is the Think Talk Write learning model. The purpose of this research is to remediate misconceptions about cell material by using the Think Talk Write learning model. This study used an experimental method with the type of pre-experimental research and one-group pretest-posttest research design. The subjects in this study were students of class XI IPA at SMA Muhammadiyah 5 Rancaekek consisting of 36 students using a purposive sampling technique. Based on the results of data processing, it was found that misconceptions in the pretest resulted in as much as 12.78% and in the posttest it decreased to 6.25%. So it can be concluded that the Think Talk Write learning model can reduce students' misconceptions about cell material.

Abstract

One of the main issues still faced by Indonesia is organic waste. This problem can be overcome by processing organic waste into eco-enzymes. Eco-enzymes contain alcohol and acetic acid, so they can be used as disinfectants and floor cleaners, dishwashing liquids, and detergents. This study aims to determine sensory characteristics such as aroma and color preferred by subjects for eco-enzyme production with the addition of yeast (Saccharomyces cerevisiae) and fruit peel variations. All eco-enzymes were made from organic waste in the form of fruit peel mixed with sugar and water in a ratio of 3:1:10. To determine the effect of yeast addition, eco-enzymes were made with orange peel with 2 variations, namely: 1) with the addition of yeast; and 2) without the addition of yeast. In the analysis of the effect of fruit peel variations, eco-enzymes were made with 6 variations, namely: 1) orange peel; 2) orange peel and pineapple peel; 3) orange peel and banana peel; 4) orange peel and papaya peel; 5) orange peel and apple peel; and 6) a mixture of all fruit peels. After one month of fermentation, the obtained eco-enzyme products were analyzed for their sensory properties. According to the observations, the aroma characteristic of the obtained eco-enzymes is that all eco-enzyme products, on average, have a normal fermentation sour aroma, with the exception of eco-enzyme products with added yeast, which have a sharper alcohol aroma. Observations on the sensory properties of color showed that eco-enzymes have a characteristic color ranging from dark brown to light brown. Overall, most of the panelists preferred the aroma and color of eco-enzymes produced without the addition of yeast. Meanwhile, for different fruit peel variations, the panelists preferred the mixture of fruit peels compared to other variations.
