Abstract

This community service activity aims to improve the economy of the village community and bring biomaterial research innovation results through the processing of banana stems into yarn as a raw material for cloth and the creative industry. The method of implementing this service used training which consisted of the stages of program introduction, processing of banana stem waste, and commercialization. The partners for this activity were the people in Sidorejo Village, Sukosewu District, Bojonegoro Regency, which are members of youth organizations. The results of this community service activity were analyzed descriptively, and simple banana stem processing positively impacted new knowledge and sources of income. The people of Siderejo village got additional daily income, activities for local economic development, and added value in knowledge, affective, and motor skills.

Abstract

The instantaneous velocity of an object is the rate of change of its position over an infinitesimally small-time interval, making direct measurement with tools like stopwatches impractical. Using two LDR sensors paired with an Arduino, it is possible to measure such small-time intervals effectively. Understanding the maximum velocity of a mathematical pendulum is critical for distinguishing between harmonic and non-harmonic oscillations. To validate the accuracy of the sensor-Arduino system, several experiments were conducted, including comparisons between Arduino measurements and those obtained from a movie tracker, as well as variations in sensor separation distances, initial oscillation angles, and pendulum rope lengths. Results showed a high level of agreement between Arduino and movie tracker measurements for pendulum crossing times. Additionally, the sensor-Arduino system successfully differentiated the effects of varying each parameter while holding others constant. The system demonstrated an accuracy of 97.86% for velocity measurements at a release angle of 5°, with an average recorded velocity of 23.350 m/s. These findings confirm the sensor-Arduino system's capability to reliably measure the velocity of a mathematical pendulum.

Abstract

The purpose of the PDTI program's community service activities is to achieve economic independence through the processing of OPEFB into geotextiles and creative industries. The implementation method uses training and assistance in processing OPEFB into fiber using fibrillation milling tools and arranging them into non-woven textile sheets to be applied in diversifying products with high economic value. Participants in PDTI activities are farmer groups from Wirajaya Village, Bogor Regency, which is <100 m from the IPB Dramaga. The evaluation instrument uses pretest and posttest on the quantitative value of knowledge, skills, and motivation in absorbing the technology provided through training. The results of the evaluation showed a significant improvement in people's knowledge, skills, and motivation. This program not only opens up new business opportunities but also contributes to environmental conservation through organic waste reduction and the promotion of a circular economy. In addition, this program has also increased to have a positive impact on the community in terms of knowledge, motivation, and skills. Meanwhile, the results of intensive training and assistance to the community are also able to convert waste into value-added products such as nonwoven geotextiles.

Abstract

This community service program aims to develop sustainable geotextiles made from local biomass. It involves training farmers in their production as an effort to reduce plastic use, improve soil health, and increase yields of papaya and chili crops. This community service implementation uses a participatory approach targeting farmers who are members of the "Karya Tani" farmer group in Desa Sidorejo, Bojonegoro Regency, East Java, with a total of 25 participants. The results of this service indicate that plastic mulch can be replaced with geotextiles made from local biomass in maintaining soil moisture, weed control, sunlight absorption, and water management. The best results were obtained from coconut coir geotextiles compared to straw, yielding 500 kg of papaya harvest from a 0.25-hectare plantation. Ultimately, this community development project aims to promote sustainable agriculture, empower rural communities, and contribute to a circular economy.

Abstract

Lecturer service is an activity that disseminates research and innovation results to village communities. The program's main objective is to improve the economy of village communities in the creative consumer goods industry made from banana stem fiber. The implementation of the service includes interactive discussions and training in production and commercialization. The partner for this activity is the farmer group Karya Tani, which includes youth and homemakers in Sidorejo Village, Sukosewu District, and Bojonegoro Regency. The activity results are analyzed based on the increased knowledge and skills observed before and after the activity. The results show that society has experienced increased handicraft production to produce products with designs and variations that have high selling value. This can increase sales and the household economy by using local natural resources, especially banana stem waste.
