Abstract

This study aims to determine the most effective type and dosage of nitrogen fertilizer in cocoa nurseries and to evaluate the level of nitrogen absorption by cocoa seedlings with various types and dosages of nitrogen fertilizer. This study was conducted at the Experimental House of the Plantation Crop Cultivation Study Program, Pontianak State Polytechnic. The method used was a non-factorial Randomized Block Design (RAK). The experiment consisted of 10 treatments, each repeated 3 (three) times, resulting in a total of 30 experimental units. Each unit consisted of two plants, resulting in a total of 60 plants. The parameters observed in this study included plant height, number of leaves, leaf area, plant fresh weight, plant dry weight, and nitrogen absorption. The type and dosage of nitrogen fertilizer significantly affected plant height, leaf area, and nitrogen absorption. The highest nitrogen absorption rate in cocoa plants was obtained with nitrate fertilizer at a dose of 2.07 g N, resulting in an absorption value of 10.51%. Urea, ZA, and Calcium Nitrate fertilizers at a dose of 1.38 g N were found to be the most effective and recommended, as the use of smaller amounts of fertilizers produced results that were not significantly different compared to the use of Urea, ZA, and Calcium Nitrate at a dose of 2.07 g N.

Abstract

The majority of residents in Punggur Kapuas are engaged in farming, primarily in horticulture and food crops, making agriculture a pivotal economic sector in the region. However, a significant issue has been the heavy reliance on chemical pesticides and fertilizers, which not only pose environmental risks but also indicate a lack of knowledge regarding sustainable and eco-friendly farming practices. The continuous use of chemical inputs has led to soil and water pollution, as well as disruptions to the natural ecosystem. To combat these challenges, this initiative focuses on training and educating farmers in the production of natural botanical pesticides and organic compost. The project encompasses needs analysis, collaborative design, outreach and training, monitoring, and financial analysis to compare the costs of natural alternatives with chemical inputs. The training component covers two main aspects: the production of botanical pesticides using readily available natural materials such as papaya leaves and garlic, and the creation of organic compost from organic waste. Compost production has a host of benefits, including improved soil fertility and reduced dependence on harmful chemical fertilizers. The method used is by counseling, discussion and direct practice in the field. The outcomes of this initiative include enhanced knowledge and skills among the farming community in Punggur Kapuas regarding the creation of safe and environmentally friendly botanical pesticides, a reduction in the use of chemical pesticides, increased productivity of organic crops, and heightened awareness of the importance of sustainable farming practices. The project has already demonstrated positive impacts, with participants gaining practical expertise in botanical pesticide and compost production. The initiative aims to encourage the adoption of organic farming practices and environmental sustainability, thereby benefiting the local economy and ecosystem. Future efforts may include extension activities, active mentoring, and supplementary skills training to further advance organic crop cultivation and promote sustainability in local agriculture.

Abstract

Makmur Jaya Farmers Group is a partner of this PKM program.Teh group still relies on synthetic pesticides and traditional pest control methods due to limited trust in biopesticides. They also lack understanding of vegetable cultivation techniques based on the substitution of synthetis pesticides with biopesticides usingthe 6T principles, have limited skills in proper pesticide application, and require adequate spraying equipment. This PKM activity aims to shift the farmers mindset toward biopesticides, provide knowledge on vegetable cultivation through synthetic to biopesticide substitution appling the 6T principles, enhance their pesticide application skills and provide spraying equipment as assistance. The program began with a needs assessment, followed by socialization, training sessions, hand on practice in environmentally friendly pest and disease control, and the handover of donated sprayers. As aresult, the famers knoeledge and skills in eco-friendly OPT management significantly improved. Participans showed great enthusiasm and expressed commitment to transition from chemical pesticides to biopesticides.

Abstract

This study aimed to analyze the potential of active compounds in pegagan (Centella asiatica) as natural antifungal agents using an in silico approach with PASS Online, SwissADME, and pkCSM. The PASS Online analysis showed that most active compounds of pegagan had antifungal activity probability (Pa) values above 0.5, indicating relatively high biological potential. The compounds with the highest activity were 3-O-beta-D-Glucopyranosyl sitosterol (0.722), Centellin (0.715), Centellicin (0.655), Asiatic acid (0.651), and Kaempferol (0.651). Triterpenoid, flavonoid, and sesquiterpene compounds are known to act through mechanisms including disruption of the fungal cell membrane, inhibition of cell wall synthesis, interference with energy metabolism, and enhancement of oxidative stress in pathogenic cells. SwissADME analysis indicated that the majority of compounds exhibited good solubility, moderate lipophilicity, and bioavailability scores consistent with biological activity. Acetylursolic acid showed the highest bioavailability score of 0.85, while most other compounds ranged between 0.55 and 0.56. The drug-likeness results demonstrated that most compounds complied with Lipinski, Veber, and Muegge rules, indicating their potential as bioactive antifungal candidates. Physicochemical property analysis revealed TPSA values, hydrogen-bond donors and acceptors, and molecular flexibility that support membrane penetration and interactions with fungal biological targets. In addition, pkCSM results showed that most compounds were non-mutagenic, non-hepatotoxic, and exhibited relatively low environmental toxicity. Overall, the results suggest that pegagan has strong potential as a source of environmentally friendly natural antifungal compounds and may be further developed as a biofungicide for controlling fungal diseases in oil palm plants.
