Abstract

Stunting is the impaired growth and development that children experience from poor nutrition, repeated infection, and inadequate psychosocial stimulation. Stunting is an issue that has a big impact. Infants and toddlers may experience morbidity and death in the near term as a result. Low intellectual and cognitive capacities can be caused over the long term, as well as problems with degenerative diseases and the lowest quality adult human resources. The average prevalence of stunting toddler in Indonesia in 2015-2017 was 31.4%, far above the WHO limit of 20%. Based on this idea, this community service was carried out with the aim of educating mothers with the family walfare movement community (FWMC) about the importance of knowledge on how to process food from natural ingredients such as Moringa leaves and pumpkin into cookies as functional food for stunting prevention in childrens in Tanjung Morawa Regency. This activity received a very good response and high enthusiasm from FWMC and headmans. This activity was attended by 35 participants consisting of 25 mothers and 10 people as headman. Furthermore, an observation survey was conducted by providing questionnaires to measure the level of understanding of food processing from natural ingredients as functional foods for the prevention of stunting in children. Observations showed that arround 96% of mothers after participating in this activity knew what stunting was, the causes, prevention of stunting and how to process food as functional foods that could reduce the prevalence of stunting in Buntu Bedimbar Village, so that they could apply in their respective households for the health.

Abstract

Garlic is a horticultural plant that is used as a flavoring and also has pharmacological benefits. Local Timor Garlic, known as Eban Garlic, is one of the local varieties of garlic from Indonesia. Eban garlic is one of the leading commodities in North Central Timor Regency whose cultivation is carried out for generations. To increase the yield of garlic, the growth and development of these plants must be considered. Growth and development are part of the biological processes of organisms. In plants, primary growth occurs at the growing point, namely the meristematic tissue at the tip of the shoot and the tip of the plant root. In this article, we will examine the effect of exposure to magnetic fields on the mitotic index of Eban garlic root tip cells. The results showed that the greater the exposure to a given magnetic field, the smaller the mitotic index. The control treatment had the highest mitotic index of 36.56% and exposure to a magnetic field of 20.03 mT had the lowest mitotic index of 20.03%. The results of the study based on the time of observation, the prophase phase had the greatest mitotic index, which was 84.21% in the control treatment. This means that exposure to a magnetic field that is too high can slow down the cell division of Eban garlic roots.

Abstract

One of the topics that need to be understood as a student teacher candidate is the taxonomy and morphology of plants including the names of their species. Urban forests provide alternative learning resources that can be created in the form of videos. The video was uploaded on the Youtube channel to help learning during the pandemic, which reduces offline activities. It is hoped that making Urban Forest videos and uploading them to Youtube media will be a solution to urban forest concerns. The purposes of writing the article include: 1) identifying spermatophyta in the urban forest of Purworejo; 2) make an urban forest learning video; 3) analyze students' understanding of urban forests and their vegetation. The method used is urban forest exploration, making videos, as well as pre and post test designs by giving online test questions after watching the video. Making a forest video begins with identifying plants. There are 17 species used in making urban forest videos. The dominant vegetation in the Purworejo urban forest is acacia, teak, and mahogany. A learning video with a duration of 25 minutes 54 seconds uploaded on a personal Youtube channel, namely Fajar Adinugraha Channel with the link https://youtu.be/trPQ2yLBpWw. In its creation, the Pl@ntnet application was used to assist identification with the help of wikipedia. The application of learning videos via youtube was able to increase the score of 28.56 points from the pretest score so that there was a significant difference between the pretest and posttest scores for knowledge of urban forests and their vegetation.

Abstract

Andaliman (Zanthoxylum acanthopodium DC) is a plant that grows and is widely used in Sumatra, especially by the Batak tribe (North Sumatra). Andaliman is empirically used for the treatment of diarrhea, toothache, and is a natural food preservative. Resistance increase of antifungal drugs to Candida albicans, so research is needed to find new ingredients that are effective as antifungals. The use of traditional medicines derived from plants can be an alternative for the community as an antifungal. The aim of the research was to determine the class of active compounds and the potential of andaliman fruit extract to inhibit the growth of C. albicans. The extraction process uses the maceration method with 70% ethanol and aquadest as a solvent. The antifungal activity test method used was the disc diffusion method and the phytochemical test using the Harborne method. The concentration of andaliman extract used was 50%, 40%, 30%, 20% and 10%, positive control was fluconazole and negative control was distilled water. The results showed that the andaliman extract was able to inhibit the growth of C. albicans with the lowest concentration of 10%. Andaliman extract (ethanol and aquadest) contains active compounds in the form of flavonoids, tannins, saponins, and steroids.

Abstract

Thromboembolic disorders can cause various life-threatening cardiovascular diseases. Anticoagulants are the most common treatment for thromboembolic disorders. Organosulfur compounds in onions, such as allicin and flavonoid compounds, have anticoagulant properties. The purpose of this study is to test the anticoagulant activity of onions extracted by maceration method using 96% ethanol as a solvent. The anticoagulant test was performed on samples of blood groups A, B, AB, and O using the Lee-White method. Six tubes were filled with 1 cc of each blood sample with treatments including control (without treatment), negative control (96% ethanol), positive control (EDTA), and variation of extract concentrations 5; 7.5; 10%. The results of 96% ethanol extract of Onion (Allium cepa Linnaeus) using the maceration method contains secondary metabolites including flavonoids, saponins, and phenols. The onion extract had a significant mean difference (p < 0.05) with the EDTA positive control group and did not produce a significant mean difference (p > 0.05) with the untreated group, so the onion extract with a concentration of 5; 7.5; 10% extracted with 96% ethanol solvent using maceration method had no anticoagulant activity. Blood type A, B, AB, and O did not have a significant difference in the mean blood clotting time with a value of P = 0.504 (p > 0.05).

Abstract

Sugarcane (Saccharum officinarum L.) is a national sugar-producing plant. One of the declines in sugar production is caused by pests and diseases and improper control. The study aims to make an inventory of arthropods in sugarcane at the age of 1,5 – 3 months, 4 – 10 months, and < 11 months in order to obtain information on these matters. The research was carried out in three plantation areas in Sumber Perkul, Gedangan, Malang and at the Basic Laboratory of the Universitas Islam Raden Rahmat Malang during March – May 2022. This study used the relative method (Sticky yellow traps, pitfall traps, light traps) and the absolute method (visual control). The results of this 14.932 individu, study obtained 68 families from the Arachnida and Insecta classes, with groups of predatory roles, parasitoids, herbivores and others. The Important Value Index of dominant natural enemies (Parasitoid) Dolichopodidae (45%), Detritivor arthropod (Drosophilidae) and Polinator arthropod (Noctuidae) (26%), Herbivora arthropod Delphacidae (15%), and natural enemies (Predator) Coccinelidae (14%). The conclusion is that from all the calculated indicators there is no group of arthropods that dominates, the diversity is moderate, and the distribution is evenly distributed. There is a change in composition, but in all indicators the calculation of the entire age of the sugarcane plant is still in the stable and balanced category.

Abstract

Students have the opportunity to carry out Biology practicums through real laboratories in labs and virtual laboratories during post-pandemic hybrid lectures. In this regard, this study aims to compare the effectiveness of real laboratory and virtual laboratory and compare the effectiveness of both through hybrid lectures in improving the critical thinking skills of elementary school teacher education students at Universitas Negeri Semarang. This type of research is a quasi-experimental study with a control group pretest-post-test design. The population in this study were second-semester students taking science laboratory courses, with a sample of 94 students. The research will be carried out at the elementary school teacher education campus, Universitas Negeri Semarang, Central Java in April-June 2022. Biology practicum activities using real laboratories as opposed to using virtual laboratories show that virtual laboratories and real laboratories are effective in improving critical thinking skills. The N-gain score in the virtual laboratory group was 0.4494 (medium) and the N-gain score in the real laboratory group was 0.4867 (moderate). Even though the N-gain is in the moderate category, the score is higher in the real laboratory, so it is concluded that the real laboratory is more effective for increasing critical thinking skills through hybrid lectures.
