Abstract

During the Covid-19 period, it was considered quite disruptive to the economy of every family. One promising entrepreneurial opportunity during this pandemic is the use of waste to become valuable goods. Kokedama is a gardening technique from Japan that can reduce plastic pots, an alternative to indoor plants with aesthetic value and high selling value. This service aims to provide training in making kokedama to Sukarami District Family Welfare Advisors (PKK). The community service method uses a training method consisting of three stages: the delivery of material, demonstrations, and practice of making kokedama, and evaluation of training activities. The results of this service, the community response to the material, stated that 100% of training participants did not know kokedama, 60% of participants were satisfied with the kokedama training, and 50% of participants noted that the time used was quite efficient for training and practice. In the future, the acquired skills are expected to provide provisions for improving family welfare through innovating ornamental plants by utilizing coco fiber waste to become kokedama.

Abstract

Swamps are part of relatively flat land along the coast, streams or lakes and there is vegetation in the form of water plants, leading to the land up to ± 100 km which is generally affected by tides from the surrounding rivers. The method used in this study is a qualitative descriptive method, namely a method of analysis that seeks to explain the conditions of the object of study according to certain criteria so that it can provide a real picture of what is happening in the research place. Public Perception of Swamp Function in the Musi Rawas Area. People living in O. mangunharjo Village use swamps to help farmers in the use of conversion of agricultural land. However, to find out people's perceptions of the function of swamps, there are ten questions to analyze the community's perceptions of the function of swamps in the Musi Rawas area. From the research activities, it is known that from the community's perception of the function of swampland in O. Mangunharjo village, Musi Rawas Regency, there are many activities or activities that occur around swamps carried out by farmers such as; looking for grass for livestock, then hoeing or plowing the fields and farmers who plant vegetables considering that swamps are very important to the balance of the environment, especially in the economy of the people around O. Mangunharjo village in Musi Rawas Regency, there are 2 respondents who do not know the impact of the damage the swamp ecosystem affects the surrounding environment and 3 respondents know its impact. Based on PKL activities, it can be concluded that the community knows the function of swamps in the surrounding settlements, namely that the presence of swamps can balance the ecological functions of the environment.

Abstract

The learning process is limited, causing the learning carried out by the teacher to be less than optimal. Teachers only carry out learning activities with limited time. The purpose of this study was to determine the use of learning models, the use of media and technology, and to find out the obstacles to the use of learning models. This type of research uses a form of qualitative research with descriptive methods. The population and sample in the study included MAN 1 Palembang with the research subjects being biology teachers and students in grades X, XI, and XII. Data collection techniques used observation, interviews, and documentation. The results showed that: (i) The implementation of biology learning carried out by teachers during face-to-face learning was limited to using conventional learning models including questions and answers and lectures so that learning only slightly involved active students. The use of media and teaching materials only comes from youtube, LKPD, and handbooks, (ii) Constraints in the application of learning models during face-to-face are limited, namely, the teacher's difficulty in explaining the material because the learning time only lasts 30 minutes so it is difficult for teachers to manage time when using syntax learning models and teachers' knowledge of learning models are also still low; (iii) limited face-to-face learning has not been able to improve student learning outcomes. The results of the research become a form of evaluation for madrasas so that teachers continue to pay attention to professional and pedagogic competencies as teacher role models in the 21st century.Kata kunci: Biologi, Model Pembelajaran, Tatap Muka Terbatas, Pandemi
