Abstract

The management of household organic waste in rural areas remains an environmental problem, including in Denggen Timur Village, Selong District, East Lombok Regency, where most waste is still disposed of without being processed. However, organic waste has great potential to be reused as valuable products, one of which is liquid organic fertilizer (POC). This activity aims to increase community knowledge and skills in processing household organic waste into POC as an alternative to environmentally friendly fertilizers. The methods used include a preparation stage through field surveys, an implementation stage in the form of socialization and direct practice of POC production, and an evaluation and reporting stage. The activity was carried out with the involvement of the Sopok Kena Farmers Group Association (Gapoktan), the village government, and resource persons from the West Nusa Tenggara. Province Environment and Forestry Service. The results of the activity showed an increase in the community's understanding and enthusiasm for organic waste management, as well as the participants' ability to independently produce liquid organic fertilizer. The POC product that was produced has undergone a fermentation process and was distributed to the community to be applied directly to plants. This activity contributed to reducing organic waste, increasing environmental awareness, and supporting community-based sustainable agriculture in Denggen Timur Village.

Abstract

Fruit flies (Bactrocera sp.) are one of the major pests of chili pepper plants that can cause damage and reduce crop yields. Therefore, plant-based attractant alternatives are needed as a means of controlling fruit flies. This study aimed to determine the effect of basil leaf extract (Ocimum sanctum L.), clove leaves (Syzygium aromaticum), and a mixture of both extracts on the number of fruit flies captured, to determine the effect of different extract concentrations, to identify the most effective extract concentration, and to identify the species of fruit flies captured in the traps. This study was conducted on chili plants using a Randomized Block Design (RBD). Data were analyzed using the Kruskal-Wallis test, followed by Pairwise Comparisons. The research results showed that using traps with basil leaf extract, clove leaf extract, and a mixture of the two extracts had significantly different effects on the number of fruit flies caught (p < 0.05); however, further analysis showed no significant difference among the types of extracts (p > 0.05). Different extract concentrations had a significant effect on the number of fruit flies caught (p < 0.05). Post-hoc test results showed that a 20% concentration was significantly different from the control but not significantly different from the 30% concentration, so 20% was established as the lowest effective concentration. The fruit fly species identified during the study were Bactrocera carambolae, Bactrocera dorsalis, Bactrocera kandiensis, and Bactrocera umbrosa.
