Abstract

Indicators are substances that can be used to show the properties of a substance through a special change in its color. The types of plants used in this study as natural indicators are found in the surrounding environment for example purple sweet potatoes (Ipomea Batatas L) and butterfly pea (Clitoria Ternatea L). This research was conducted in 5 stages: 1) cut the purple sweet potato and butterfly pea into small pieces and then mash until smooth: 2) pour 5 tablespoons of alcohol and then leave until it settles; 3) pour the extract on 3 test tubes to test acid, base, and control; 4) drip the test solution on 2 test tubes; 5) then do testing to identify discoloration in purple sweet potato extract and butterfly pea a large amount of anthocyanin content in butterfly pea (Clitoria Ternatea L) affects the results of acid and alkaline testing so that the test results on butterfly pea extract (Clitoria Ternatea L) show a clear change in color. The purpose of this study is to identify the effectiveness of purple sweet potato extract (Ipomea Batatas L) and butterfly pea (Clitoria Ternatea L) as natural indicators of acid-base so that it can be used as an alternative learning medium.

Abstract

This study aims to determine the identification of acid-bases with natural indicators. This, is done because acid-base testing uses a lot of litmus paper. In dragon fruit extract and turmeric extract, there is a more concentrated color pigment content to determine the acid-base concentration. So we want to increase its sensitivity to detecting acid- bases. The method used in this study is experimental. The results of the study can be used to assist the public in knowing the benefits of dragon fruit and turmeric to detect acid-base solutions.

Abstract

Plants or plants are living things just like humans and animals. Plants also move which aims to show irritability and to respond to the stimuli it receives. Movement in plants is divided into several categories, one of which is the motion of tropism, which is also divided into more specific movements. This writing aims to find out and study the mechanism of motion of the wijaya kusuma flower. Wijaya Kusuma Flower Plants are plants that have special movements and are different from the movements of other plants. Most people do not know that the movement of the wijaya kusuma flower plant is called scototropism. This motion can also be said to be negative phototropism because the plant will move away from the sun when the light comes close to the plant. One of the characteristics of the Wijaya Kusuma flower itself is that it can only bloom at night for between 1 and 2 hours and will wither the next morning.

Abstract

Green jungle fowl (Gallus varius) is widespread in nature and community forests. This study aims to identify distribution patterns, habitat profiles, and the potential of green jungle fowl (GJF) as a source of biological learning based on a biocultural approach (biodiversity, cultural diversity, and language diversity). The case study was used for extensive bird exploration in a customary forest, Hutan Adat Bukit Demulih Bangli (HABD), from February to June 2022. Data on distribution patterns were collected with a combination of free-range, line transect, and point-count techniques and habitat profiles with physiognomy methodology. Meanwhile, document analysis and the concept map were used to demonstrate the potential of the GJF in HABD as a source of learning. The results revealed that GJF was unequally distributed, with a population at each observation point ranging from 2 to 10. The bird prefers forested areas dominated by shrubs with several trees and, therefore, has an open canopy that allows sunlight to reach the forested floor. Local knowledge and practices in the preservation of GJF and HABD are excellent resources for learning various biological materials and concepts in the context of biodiversity, culture, and language.

Abstract

  Jelly candy is made from gelling agents and essences to produce a variety of flavors, a clear transparent appearance, and a chewy texture. In general, jelly candy uses gelatin as its gelling agent. Doubts about the halalness of gelatine make research into the potential of other gelling agents necessary. Carrageenan can replace gelatin as a gelling agent because of its gelling ability. This study used turmeric extract as a colorant for jelly candy. This study aimed to determine the effect of adding sugar and turmeric extract on the water content and organoleptic of turmeric jelly candy (Curcuma longa L.). This study used a completely randomized design with two factors: variations in sugar concentration (25%, 75%) and turmeric extract (5%, 10%, 15%). The results showed that the combination of turmeric (C. longa) extract concentration significantly affected water content; the greater the concentration of sugar and turmeric extract affected the color and taste of jelly candy. The concentration of carrageenan and konjac mixture that the panelists most liked was 75% sugar. Meanwhile, the concentration of turmeric extract that the panelists most liked was the addition of 10% turmeric extract.

Abstract

Important sources of vitamin C in food mainly come from fruits and vegetables. One type of fruit that contains vitamin C and is much in demand by the public is pineapple. To extend the shelf life of pineapple fruit can usually be done by processing the fruit into other preparations. But on the other hand the content of vitamin C in fruit and food will be damaged due to the oxidation process by the outside air, especially when heated. This study aims to determine the levels of vitamin C in fresh pineapple and processed varieties of pineapple. This research method is descriptive by analyzing the content of vitamin C in fresh pineapple and its processed variations using the UV-Vis spectrophotometry method. Based on the results of the study, the levels of vitamin C in fresh pineapple, pineapple syrup and candied pineapple were (95.75 ; 49.09 ; 44.09) mg/100g, respectively. Based on the statistical test results, a significant value of p>0.05 was obtained, which meant that the data was normal and continued with the paired parametric T test. The result of the test is p<0.05. There are differences in the value of vitamin C levels in fresh pineapple and processed variations.
