Abstract

The training activity for creating innovative learning media in the independent curriculum was carried out in order to develop the competence and skills of teachers related to creating creative and interesting learning media. The activity was carried out in Kolbano, South Central Timor Regency, East Nusa Tenggara Province in 2024. The basis for its implementation was the need for teachers to develop their competence in utilizing technology in creating learning media according to the demands of the current independent curriculum. This activity aims to improve teacher competence in utilizing technology to design interesting and innovative learning. The innovative learning media that were the topic of this training were Google Sites, Wordwall and QuizWhizzer. Teachers in Kolbano generally only teach using lecture and group discussion methods, and use conventional learning media such as power point displays and video materials. As a result, students are less motivated and feel bored in learning activities, while the nature of the independent curriculum demands active interaction of students in learning. Therefore, through this training, teachers are trained and assisted in developing innovative learning media until the product is produced and used in learning. This learning media can be presented interactively and attractively so that it can motivate students to participate in learning. Teachers will also be more creative in innovating to develop media that attracts students' interest in accordance with the nature of the independent curriculum.

Abstract

The Nekamese region has the potential for coconut trees that are traditionally converted into coconut oil. Traditional coconut oil is of poor quality in terms of health and requires a lot of energy to produce. While coconut can be processed into pure oil and when sold, it will be more expensive. One way to process virgin coconut oil is by fermentation. Such knowledge is exactly what the community needs. But the partners do not have knowledge about processing pure coconut oil. Therefore, the proposed solution for partners is to organize training on pure coconut oil production.

Abstract

Technological advances provide educators with the freedom to create quality learning that meets the needs and learning environment of students. A crucial aspect for teachers to consider in realizing effective learning is the use of interactive learning media tailored to the characteristics and needs of students. The use of digital technology to develop interactive learning media is a necessity in today's learning process. Training and mentoring for teachers in Malaka to develop interactive and innovative digital media is based on the need to improve their competency and skills in utilizing technology to develop learning media. This activity aims to improve teachers' competency and skills in utilizing technology to design engaging and interactive digital-based learning using Book Creator and QuizWhizzer. Monotonous learning activities, often based on lectures and group discussions, with the use of conventional learning media, tend to make students passive and easily bored, resulting in a lack of student interest in learning and a decline in the quality and outcomes of learning. Furthermore, technological developments demand increased competency, including in preparing engaging learning media. Therefore, through this training activity, teachers are provided with guidance and training in developing interactive learning media so that the resulting products can be directly used in the learning process. The developed media is designed to be interactive and engaging, thereby increasing student motivation. Furthermore, this activity also encourages teachers to be more creative and innovative in creating learning media that can attract student interest. The training activities ran smoothly and effectively, as evidenced by the high enthusiasm of teachers and the increase in knowledge and skills related to the training material. The mentoring results also showed an improvement in the quality of learning through active student interaction in learning with the help of digital learning media, which resulted in improved interest and learning outcomes.

Abstract

A study has been conducted to isolate and identify halotolerant bacteria in saline soils from the coastal areas of Oebelo White Sand Beach and Pariti Beach. The sampling method used was random sampling. During sampling, pH, electrical conductivity (EC), and soil temperature were also measured. Bacterial isolation was performed using a serial dilution technique, resulting in three pure isolates from each beach sand sample. The isolates were cultured on Nutrient Agar (NA) medium and incubated at 37°C for 24 hours. The colonies obtained were small, round, and white. The isolates were then purified using the streak plate method. The halotolerant test was conducted using Tryptic Soy Agar (TSA) medium without added salt. The results showed that the bacterial colonies were halotolerant, as indicated by growth after 24 hours of incubation. Further biochemical tests, including motility, citrate utilization, urease, and sugar hydrolysis, revealed that all isolates from Oebelo White Sand samples showed positive results for all tests, whereas isolates from Pariti Beach exhibited some variations. These findings indicate that the isolates were capable of hydrolyzing urea into ammonia, utilizing citrate as a carbon and energy source, and fermenting sugars present in the medium.
