Abstract

Science learning cannot be separated from practical activities. Practical activities provide benefits for students as a vehicle to practice basic skills in conducting experiments which are very much needed as science student teacher. The Covid-19 pandemic has prevented lecture activities including practical work from being carried out in the laboratory as they should. As a solution, students continue to carry out practical work independently in their respective residences by using tools and materials that are easily found in the surrounding environment. This study aims to capture the perceptions of science education students who are enrolled in the school's science practicum lecture on the implementation of independent practical work based on materials, practical work guide, and the implementation. The research method used is descriptive research with a quantitative approach. The instrument used was an online questionnaire which was distributed to 95 respondents. The results showed that students' perceptions were quite diverse on materials, practicum guides, and the implementation.

Abstract

Indonesia is a developing country that has abundant natural resources, especially palm oil. In Indonesia, a lot of forests are made into oil palm plantations and palm oil mills have been spread throughout Indonesia, one of which is PT Incasi Raya SJAL Lunang Silaut. Here many workers work from the office sector to the fertilization sector. Here they use chemicals that we often hear, namely pesticides . Despite their adverse effects on humans and the environment, pesticides,including herbicides, are often used in oil palm plantations.Paraquat Has been used for more than 40 years in both large and small plantations, paraquat dichloride, known simply as 'paraquat', is one of the most widely used herbicides in the world. In Indonesia, 'paraquat' is sold under the name Gramoxone.According to the World Health Organization (WHO), there are not 20,000 people per year, due to pesticide poisoning. It is estimated that 5,000 - 10,000 people per year experience a very fatal impact, such as experiencing cancer, disability, infertility and liver disease.Here will discuss how the impact will occur if workers do not use safety equipment at work and how to use chemicals properly.not only bad for humans, these pesticides and paraquants are also bad for the environment because if they are used excessively they will reduce soil fertility and plant growth is not normal.

Abstract

Kawa Daun drink is a beverage made from dried coffee leaves and is a typical drink of West Sumatra. A survey of the process of making kawa leaf drink has been carried out by visiting the places where the manufacture of kawa leaves is spread in three regencies in West Sumatra, namely Tanah Datar District, Agam District, and Lima Puluh Kota District. This study aims to obtain information on the process of making existing and developed Kaawa Daun drinks in West Sumatra. Data were obtained by interviewing techniques, direct observation, and assisted with a list of questions. From the results of observations on the process of making existing Kaawa leaves and developing in West Sumatra it is known that there are three processes of making kahwa drinks or extraction processes namely 1) cooking (water and coffee leaves are cooked simultaneously until boiling) 2) brewing (brewed coffee leaves with hot water 80-90oC), and 3) dissolution (water is boiled until then the coffee leaves are inserted and allowed to boil for 3-5 minutes).

Abstract

In order to examine local knowledge from the fermentation process used to make tapai cassava, this observation will link it to ethnoscience. This observation was made in the areas of Padang Pariaman, Petak Talao Mundam, Nagari Katapiang, and Jl. Minang Kabau International Airport. With the sources Mr. Sisul and Mrs. Maryam. In making cassava tapai it has several stages, starting from selecting good cassava, peeling the cassava skin, cutting, washing, boiling, cooling, giving yeast, the fermentation process to become a cassava tapai. The fermentation process in making cassava tapai gives changes in color, aroma typical tapai, soft texture, and sour taste. Tapai cassava has many benefits such as; to expedite the menstrual process, get rid of acne, medicine for wounds for diabetics, warm the body, remove black spots, and etc.

Abstract

Banyan (Ficus Benjamina l.) Is a type of tree that is found in Indonesia. Banyan tree grows with hanging roots that grow bigger and bigger. This paper identifies the air content around the banyan tree (Ficus Benjamina l.). The results of observations show that there are several compounds contained in the banyan tree. In the midst of the public circulated rumors that say that many mystical things that make the banyan tree often sacred and feared. One of the rumors circulating is not being able to sleep under a banyan tree because it could die. The conclusion of this observation is that the public's knowledge is correct, that the prohibition of sleep under the Banyan tree can cause fatal consequences, namely death. It's just that people consider it related to mystical things associated with the existence of supernatural beings. Apparently the assumption was wrong after being studied scientifically. These observations reveal that the banyan tree's hanging roots produce CO2 gas which is toxic to the human body. If the CO2 gas is inhaled by humans and then mixed with the bloodstream, the blood hemoglobin can bind more strongly with CO2 and is toxic. Blood flow will flow to the brain and interfere with the work of the brain, so the fatal result that can occur is death.

Abstract

Learning media, namely acting as a mediator of information between the source (teacher) and the recipient (student), is one of the resources that can assist teachers in offering simpler and more effective learning materials (student). The goal of this study is to identify and evaluate the media that teachers in SMPN 30 Padang and the SMP Development Laboratory at Padang State University use to engage students in the science learning process. Analyzing the information from the learning material employed was another goal of this study. This form of research, which aims to examine the needs of learning media, is qualitative descriptive research. Science instructors from SMPN 30 Padang and SMP Pembangunan Laboratorium in Padang City served as the study's participants. Based on the research data, it is known that there are differences in the use of instructional media between the two schools, where in SMPN 30 Padang the use of instructional media is better than SMP Pembangunan Laboratorium.

Abstract

The construction of the Minangkabau traditional home is distinctive. The gadang house was built with local wisdom, which can be related to the Minangkabau traditional community's understanding of how to interact with nature. This essay examines the components and modifications of Rumah Gadang's construction culture system from the perspectives of ethnoscience and community wisdom. The Gadang House, which serves as the King's Palace, is the subject of the research, and the methodology utilized is descriptive qualitative with direct surveys to the field utilizing interview techniques. The results of the study show that the construction and spatial arrangements in the Rumah Gadang building are very closely related to the local wisdom of the Minangkabau people and also the application of science elements in its construction.
