Abstract

Community service activities in the form of counseling and training in making organic fertilizers based on Photosynthetic Bacteria (PSB) have been carried out in Sendangdalem Village, Padureso District, Kebumen Regency on June 3, 2025. This activity aims to improve the knowledge and skills of farmers and village youth in the application of organic agriculture and environmentally friendly PSB fertilizer manufacturing technology. The implementation of the activity began with coordination and preparation, followed by counseling on the concept and benefits of organic farming, as well as direct PSB fertilizer making training, where participants were actively involved in each stage of the process. Evaluation is carried out through pre test and post test to measure the effectiveness of activities. The results of the evaluation showed an increase in the average score of participants from 66.82 in the pretest to 70.59 in the post test, which indicated an increase in the understanding and skills of the participants. However, some participants have not experienced a significant increase, so further assistance is needed. Overall, this activity has a positive impact in supporting sustainable agriculture efforts and increasing the capacity of village communities in managing agricultural resources independently and environmentally friendly

Abstract

Kepel (Stelechocarpus burahol) is an endemic Javanese plant whose natural populations are declining, requiring conservation based on scientific evidence. This study aimed to characterize the morphological variation and analyze the phenotypic relationships of kepel populations across five ecological zones in Kebumen Regency: West, South, Central, East, and North. A total of 25 individuals were examined using a quantitative descriptive survey. Vegetative traits (leaf length, leaf width, stem diameter) and generative traits (flower diameter) were measured, while environmental parameters were recorded to support data interpretation. Numerical taxonomy analysis was conducted using the Unweighted Pair Group Method with Arithmetic Mean (UPGMA) based on standardized Euclidean distances. The results showed substantial morphological variation among zones, with stem diameters ranging from 27.7 to 30.5 cm and leaf lengths from 17.5 to 19.8 cm. Significant correlations were observed between soil pH, humidity, and temperature with key morphological traits (r = 0.70–0.90). The UPGMA dendrogram revealed three major clusters corresponding to distinct microhabitats. These findings indicate local adaptation of kepel populations in Kebumen and provide a scientific basis for both in situ and ex situ conservation of local germplasm.

Abstract

Background: Purworejo Regency is one of Indonesia's rice-producing regions. Identifying new, superior varieties suitable for various soil types, such as saline soils, is expected to increase rice production in the region. Objectives: The purpose of this study is to provide recommendations for new superior rice varieties based on the highest productivity in saline land in Purworejo Regency, and to create a sustainable agricultural management model. Methods: This study uses PVS tests that can be used in other areas with similar characteristics. This study involved 17 respondents to determine the preferences of each new superior rice variety. Respondents were selected through observation and recommendations from Gapoktan based on the number of farmers active in the rice fields. Observations were also made on new superior rice varieties in the vegetative and generative phases. Observations in the generative phase, including crop yields. Parameters for observation of morphological characters include plant height (cm), number of seedlings, root length (cm), flowering age 50%, number of panicles, number of filled grains, number of empty grains, and weight of filled grain.Results and Discussion: The results of the PVS test, based on farmers' preferences for the presented superior rice varieties, were analyzed using descriptive statistics. The results of this assessment will be balanced against the study's average parameters for each variety. Through the PVS test approach and participatory preference data collection, the Inpari 34 Agritan variety emerged as the main choice, with lower farmer acceptance due to weakness in pest resistance and low productivity, despite its superior characteristics based on morphological observations. In contrast, varieties such as IPB 12S and TP-Padi 2 show relatively lower acceptance among farmers due to weaknesses in pest resistance and low productivity Conclusion: The PVS approach is effective for selecting salt-tolerant rice varieties that are well-suited to farmers’ needs and have the potential to support food security.
