Abstract

Ecoenzymes are natural ingredients formed from the fermentation of fruit and or vegetable residues that have many benefits. One of the benefits of ecoenzymes is that they can be used as eco-handsanitizers; which can be used as a candidate for handsanitizer for those who are allergic to alcohol-based handsanitizer. This study aims to determine the pH, antibacterial, antiviral, and antifungal content of the candidate eco-handsanitizer solution through alkaloid, flavonoid, and saponin test, also fungal-inhibition test. The candidate eco-handsanitizer solution was made from an ecoenzyme solution derived from fruit or vegetable residue and added with aloe vera gel and vitamin C or E. The results showed that eco-handsanitizer candidate solution derived from ecoenzyme solution with a dilution of 1:500 or 1:4 and added with aloe vera and vitamin E had a pH that tends to be acidic after 5 weeks of manufacture. The candidate eco-handsanitizer solution contained alkaloid compounds up to 2nd week for 1:500 dilution or up to 5th week for 1:4. Fungal test also showed positive results of one of the treatments in inhibiting fungal growth until the 11th day. These results were expected to be used as guidelines for further research, such as quantitative and qualitative tests for more sensitive alkaloids, for example using GC-MS.

Abstract

Research with the title “Identification of Types of Fish Captured by fishermen at TPI Wuryantoro Wonogiri that are consumed by the community”.The aims of this study are: to identify the types of fish caught by fishermen at TPI Wuryantoro that are consumed by the community as student learning materials in the Vertebrate Animal Systematic Course, Biology Education Study Program, Faculty of Teacher Training and Education, Veterans University Bangun Nusantara Sukoharjo in 2021. In In this study, fish sampling was carried out at the Wuryantoro fish auction, Gajah Mungkur Wonogiri reservoir, while identification was carried out in the laboratory of the Biology Education Study Program, FKIP Univet Bantara Sukoharjo. The results of the identification of the types of fish caught by fishermen at TPI Wuryantoro, Gajah Mungkur Wonogiri reservoir. There are 7 types of fish, of which 7 species of fish were found to be in 1 class, namely the Ostheichthyes class, included in 2 sub-classes, namely the Teleostei and acthynopterigii subclasses, included in 4 orders, and 7 families. The fish are: red snapper (Lutjanus argntimaculatus), catfish (Clarias batrachus), tilapia (Oreochromis niloticus), Tawes Fish (Barbonymus gonionotus), betutu fish (Oxyeleotris marmorat), cursed fish / cork (Channa striata), catfish (Pangasius hypophthalmus). Fisherman's catch at TPI Wuryantoro Gajah Mungkur Wonogiri reservoir, can be used as study material for students of the Vertebrate Animal Systematic course.

Abstract

The purpose of this study was to improve the argumentation skills of class X high school students by applying the Inquiry Lesson model with Google Classroom in biology learning. This research is a classroom action research which consists of 4 stages, namely planning, action, observation, and reflection. The subjects of this study were 36 students of class X SMA Negeri in Sukoharjo. The argumentation skill data is taken with an essay test instrument that refers to aspects of claim, data and reasoning. The argumentation skill data was analyzed descriptively quantitatively with the percentage technique. The results showed that the percentage score of argumentation skills in cycle 1 was 78% (28 out of 36 students) and cycle 2 was 92% (33 out of 36 students). The research data shows an increase in argumentation skills from cycle 1 to cycle 2 by 18% through the application of the inquiry lesson model. Argumentation skills are one of the main goals of science learning because students who study science must know scientific explanations about natural phenomena and use argumentation to solve problems. Argumentation skills are important for students as skills needed in the 21st century.

Abstract

Food has an expiration date. To make food have a longer shelf life, food manufacturers use preservatives as a solution. There are preservatives that are safe to use and prohibited from being used. One of the chemical preservatives prohibited from being used in food is formalin. Formalin is usually added to processed meat and fish foods. The purpose of this study was to detect the presence of formaldehyde as a preservative in consumption fish sold in several markets in Surakarta. The method used in this study is experimental. As an indicator in this study, natural ingredients were used, namely dragon fruit peel extract. This research is expected to be a solution and an alternative in detecting formaldehyde content and an effort to choose healthy consumption fish without containing harmful chemicals. The results of this study found fish containing formaldehyde, namely shark, salmon, tilapia, mackerel, and flying fish. If consumed in the long term, formalin can cause damage to kidney function, liver and cause cancer.

Abstract

This study aims to identify rare medicinal plants in Manggeh Village, Karanganyar District, Karanganyar Regency, as well as to understand the level of knowledge and understanding of the community regarding rare medicinal plants in areas with a low tendency. The research method used was field surveys, interviews, and direct observation of 40 respondents who were randomly selected from people in low inclined areas. The results showed that there were a number of rare medicinal plants in Manggeh Village. These plants have high medicinal potential and have been used traditionally by the local community. However, the level of public knowledge and understanding regarding rare medicinal plants is still limited. Although some people are familiar with rare medicinal plants in general, in-depth knowledge about their benefits, uses and potential side effects is still limited. This research provides a deeper understanding of the biodiversity in Manggeh Village and provides useful information for the community in the proper and responsible use of medicinal plants. The results of this study can also be a basis for local governments in developing policies for the conservation of rare medicinal plants.

Abstract

Red chilies are one of the important types of vegetables cultivated commercially in tropical countries. Insect pests are one of the obstacles in efforts to increase the production of red chili ornamental plants. There are some farmers who do not understand the types of pests that exist in red chili plantations. This research aims to identify the types of pests that attack red chili plants in Nangsri Manisrenggo Village and observe the symptoms of pest and disease attacks. The methods used are observation and interviews. The data obtained was analyzed descriptively qualitatively. The results of the research show that there are 2 types of disease, namely fungi that cause leaf spots, Pestalotia sp and Cercospora sp, and 6 types of pests that attack red chilies, namely: Thrips spp., peach aphids (Myzus persicae), armyworms (Spodoptera litura), flies fruit (Bactrocera spp.), mites (Tetranychus sp.; Polyphagotarsonemus sp.) and whitefly (Bemisia tabaci).
