Abstract

Indonesia has great potential to sustainably utilize both marine and terrestrial resources. However, The Harapan Baru Cooperative Group still faces various challenges, such as limited knowledge of fish storage and the use of home gardens as cultivation areas for crops. This community service activity aims to address management and production issues to improve the economy of fishermen in the Harapan Baru Cooperative Group in Tarakan City, North Kalimantan, through the integration of blue economy and green economy concepts. The approaches used in this program include surveys, socialization, training, and evaluation. The identification results obtained during the survey revealed two main issues: the suboptimal income of partners from marine products and the minimal utilization of their yards for agriculture. In the training, partners were educated on various fish storage techniques and preservation methods, as well as the production of organic fertilizer from fish waste and botanical pesticides from Siam weed. The results of the activities showed an increase in understanding and skills among fishermen, especially regarding fish storage and micro farming, which can support local economic and food security. The evaluation results concluded that the average scores obtained by the participants indicated that the majority of partners have a good understanding, with a score of 80.2% for fish storage methods and 95% for the production of liquid organic fertilizer, compost, and botanical pesticides. These results reflect the success of the community service activities.

Abstract

Eleusine indica is a dominant weed species commonly found in maize fields and can significantly suppress maize growth. The use of plant-based herbicides derived from Imperata cylindrica offers an alternative strategy for controlling E. indica. Such herbicides are considered environmentally friendly because they originate from organic materials. This study aimed to evaluate the effects of I. cylindrica weed extract on the growth of E. indica and maize plants. The experiment was conducted using a randomized complete block-design with a single factor, namely I. cylindrica extract concentration. Treatments consisted of a control (without I. cylindrica extract) and extract concentrations of 20%, 40%, 60%, 80%, and 100%. Observed variables included maize plant height, number of leaves, shoot fresh and dry weights, root fresh and dry weights, weight of husked maize ears, as well as the height, number, fresh weight, and dry weight of E. indica. Data were analyzed using analysis of variance (ANOVA), and treatments showing significant effects were further analyzed using Duncan’s Multiple Range Test (DMRT). The results showed that application of 100% I. cylindrica extract resulted in significantly lower maize plant height and a significantly reduced number of leaves compared to other treatments, except for the 80% concentration. The 100% extract treatment suppressed E. indica height by up to 10.17% and reduced the number of E. indica leaves by up to 12.5% at 2 weeks after planting. These findings indicate the potential of Imperata cylindrica as an environmentally friendly plant-based herbicide without adversely affecting the main crop.
