Abstract

Stomata are clefts of the epidermis, each lined by two guard cells. In Greek, stoma means "mouth", and the term is often used only for the stomatal pore. Stomta has long been the object of study of morphology, anatomy and physiology. In general, several technical terms are known, such as stoma, stomata complex, neighboring cells and daughter cells. In general, several technical terms have been known, such as stoma, stomata complex, neighboring cells and daughter cells. The term has been used in different meanings by groups of botanical researchers. This study was conducted to determine the type of stomata in several types of dicotyledonous and monocot plants. The study used a qualitative descriptive method to describe and describe the type of stomata in several types of dicotyledonous plants and monocotyledonous plants. The object of this research uses the abaxil leaf of several types of plants including dicotyledonous plants which include soursop (Annona muricata), mango (Mangifera indica), noni (Morinda citrifolia), breadfruit (Artocarpus altilis), and monocot plants which include: palm leaves, banana leaves, papaya leaves (Carica papaya) and turmeric leaves (Curcuma longa). The research was carried out through several stages, namely the preparation of leaf samples, making leaf preparations, observing under a microscope, documenting and describing the forms of stomata. The results showed that dicot and monocot plants have different types of stomata. Several types of plants also have the same type of stomata. Soursop (Annona muricata) has Paracytic stomata type; Mango (Mangifera indica) has anomocytic stomata type; Noni (Morinda citrifolia) has Paracytic stomata type; Breadfruit (Artocarpus altilis) has Actinocytic stomata type; The palm (Oreodoxa regia) has a Tetracytic stomata type; Banana (Musa sp.) has anomocytic stomata type; Papaya (Carica papaya) has Hemiparacytic stomata type; and Turmeric (Curcuma longa) has Paracytic stomata type.

Abstract

Problem based learning was chosen because it has a learner-centered nature and emphasizes independent learning. The purpose of this study is to describe a problem based learning model that can improve student learning achievement and analyze the increase in student understanding of the subject of the human respiratory system after problem based learning is applied. This research was conducted at SMA Negeri 2 Bungku, students of class XI MIA 2, totaling 30 students for the 2021/2022 academic year, having the address Bente, Bungku Tengah District, Morowali Regency, Central Sulawesi Province. The data analysis technique in this study was using descriptive statistics, namely calculating student learning completeness. The test achievement shows that the Teaching Completeness Criteria (TCC) in the first cycle are 70% or 21 students and 30% or 9 students are incomplete with a total of 30 students. Then in the second cycle of the Teaching Completeness Criteria (TCC) in the second cycle there were 90% or 27 students and only 10% or 3 students who did not complete the total number of students as many as 30 students. Cycle III Teaching Completeness Criteria (TCC)) with a maximum score of: 100% of the total 30 students

Abstract

Project based learning is a learning model that is student-centered, project-oriented and the results of the project are presented by students. The purpose of this study was to describe the application of the project based learning model and analyze the increase in student understanding after the project based learning model was applied. This research was conducted in class XI MIA 2 SMA Negeri 2 Bungku, totaling 30 students for the 2021/2022 academic year. The test results show the Teaching Completeness Criteria (TCC) on the subject of the human excretory system, in the first cycle 70% or as many as 21 students meet teaching mastery and 30% or 9 students do not meet teaching completeness. Cycle II there are teaching completeness is 85% or as many as 26 students meet teaching completeness and incomplete there are 15% or 4 students do not meet teaching completeness. Cycle III there is a teaching completeness is 95% or 29 students meet teaching completeness and 5% incomplete or 1 student does not meet teaching completeness. This increase in learning achievement is marked by an increase in each cycle from cycles I, II and III.

Abstract

This study aims to analyze the biology learning process during the Covid-19 pandemic. The research method used is a literature review by analyzing 15 articles on biology learning during the Covid-19 pandemic. The results show that online biology learning is less effective and there is also successfully implemented. The implementation of online biology learning requires the use of digital technology-based media, some of the media used include WhatsApp application, Google Meet, Zoom, Campus Management Services (LMS), and virtual labs. The implementation of online learning also faces various obstacles, including limited contingents, networks, and supporting devices such as mobile phones, so evaluations must always be carried out for the learning implementation to take place in the best possible way.

Abstract

Candlenut bark is a source of various bioactive compounds with antioxidant potential and or free radical neutralization. This study investigated the antioxidant activity of candlenut bark extract. The research was carried out through several stages including: sample preparation, sample extraction, making reagents, making ethanol extracts, making vitamin C solutions, measuring the maximum wavelength of DPPH, and measuring the absorbance of free radical neutralization using the DPPH method. The results showed that the ethanol extract of candlenut stems had antioxidant activity as indicated by the higher the volume of ethanol extract added to the test solution, the higher the percentage of free radical neutralization. The ratio of the volume with the percentage of free radical neutralization, which is 10 mg/mL has a free radical neutralization percentage of 8.90%, 25 mg/mL has a neutralization percentage of 26.03%, 50 mg/mL has a neutralization percentage of 44.52%, and 75 mg/mL has a neutralization percentage of 65.75%.
