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

This article reports the adsorption isotherm model of tryptamine using bovine serum albumin-modified silica adsorbent (SiO₂@BSA) obtained from Takari natural sand as a silica source. Silica was extracted from natural sand and then modified with BSA. The SiO₂@BSA adsorbent was used to adsorb tryptamine in a batch system with 5, 10, 20, 30, 40, and 50 mg/L concentrations. Tryptamine content was analyzed using a UV-Vis spectrophotometer at 423 nm. Eight models were employed to describe the adsorption isotherm of tryptamine. The modeling results revealed that tryptamine adsorption follows the Langmuir isotherm model, with an R² value of 0.938 and a maximum adsorption capacity of 7.961 mg/g. This study confirms the potential of SiO₂@BSA as an effective adsorbent for tryptamine adsorption, contributing to the development of adsorption technology for organic compounds.

Abstract

The utilization of medicinal plants in Indonesia is still limited due to the lack of community knowledge on sustainable management and utilization, as well as low awareness of the economic valuation of medicinal plants. The purpose of this community service activity is to improve public understanding of the sustainable management and utilization of medicinal plants and provide insights into their economic valuation. The methods used in this service are counseling, training, and consultation with the community, using a participatory approach. The results obtained show an increase in participants' knowledge of medicinal plants, as well as a more positive attitude toward sustainable plant management. Furthermore, participants' skills in utilizing medicinal plants and calculating their economic valuation have also improved. In conclusion, the conducted counseling and training can enhance knowledge, skills, and public awareness, which in turn can support more sustainable and economically valuable medicinal plant management.

Abstract

The amount of organic waste continues to increase along with the growing population and changing consumption patterns. This will impact the rise of greenhouse gases and the decline in environmental quality. Therefore, community service activities aim to provide education on processing organic waste into useful and environmentally friendly products in the form of liquid organic fertilizer (LOF) and bokashi as an effort to mitigate environmental pollution. The educational activities are conducted using the participatory rural approach (PRA) method, where participants are directly involved in the production of LOF and bokashi. The activities are divided into four main stages: observation, training and mentoring implementation, and activity evaluation. The target of community service is the Betlehem Oesapa Barat congregation, which is organized into the Bethlehem Farmers Group consisting of 25 people. The evaluation results show that community activities with the PRA approach have an effectiveness level of up to 96% in transferring waste management knowledge and skills to participants. This is supported by the change in knowledge about making LOF and bokashi from 8% before the educational activities to 92% by the end of the activities. About 96% of participants stated that the activities were beneficial to them, with 92% of participants wanting to independently implement the results of the activities. The follow-up to these activities includes continuous monitoring and evaluation, as well as further development related to the use of LOF and bokashi in the horticultural cultivation of the farmers' group. Additionally, efforts will be made to expand the reach to the congregation and community by the community service team of the Postgraduate program The University of Nusa Cendana in order to create a society that is aware and cares about the environment and actively participates in mitigating waste pollution in the future.

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.
