In the 1990s, potato yield in the Andisols of Dieng, Central Java, Indonesia, was approximately 30 t ha–1, but this value decreased rapidly to 12–15 t ha–1 in recent years. This rapid decline could be attributed to the use of unbalanced organic and chemical fertilizers, without the application of conservation techniques. Therefore, this study aimed to sustainably improve the local potato cultivation pattern of farmers on Andisols using biological organic fertilizers and pesticides (BOFP). A randomized block design was used with two factors, namely: 1) 20 t BOFP, 300 kg Urea, 500 kg SP 36, 300 kg KCl, and 200 kg lime ha–1, and 2) comparison with the pattern of farmers, consisting of 20 t of chicken manure, 1–t NPK, and 250 kg ZA ha–1. The potato plant mounds were tilted 10% to the contour direction, and each treatment was carried out with 16 replications. Granola seeds were used to plant potato during the rainy season from March-June 2022. The results showed that the plants cultivated using the local pattern of farmers were affected by wilt from Fusarium spp, while the use of BOFP decreased the incidence of the disease by 80%. Furthermore, the BOFP pattern significantly increased Andisols organic-C from 1.78% to 3.83% and total soil P from 5.20% to 11.34%, compared to the pattern of farmers. It also increased potato yields from 12.31 t ha–1 to 22.93 t ha–1 and the R/C from 0.85 to 1.23, compared to the pattern of farmers. Based on the results, the use of BOFP pattern decreased wilt attacks by Fusarium spp, improved the productivity of Andisols, as well as increased potato production and profits of farmers.

The Dieng region in Central Java, Indonesia, is a major horticulture commodities center, covering approximately 3,000 hectares of Andisols. Since the 1980s, long-term use of organic and inorganic fertilizers as well as pesticides has led to the accumulation of heavy metals, such as lead (Pb) and cadmium (Cd). Pb contents in Andisols generally remain below the Environmental Protection Agency (EPA) standard, except in Sikunang, and Cd exceeds the standard in both Sembungan and Jojogan Wonosobo. In potato tubers, Pb content exceeds the SNI 7378-2009 threshold in Wonosobo and Pekasiran Banjarnegara, while tubers from other areas are below standard. The Cd content in tubers from Jojodan and Kalilembu Wonosobo, as well as Pekasiran and Kepakisan Banjarnegara, also surpasses the standard, but in other areas, it is below standard. The use of remediators composed of chicken manure enriched with Pseudomonas sp, Dark Septate Endophytes (DSE), and Citronella (Cymbopogon nardus) as phytoremediators reduced Pb and Cd levels in both soil and potato tubers. Therefore, the best remediation strategy for mitigating heavy metal contamination included the combination of Pseudomonas sp., DSE, and citronella. These treatments did not significantly affect potato yield. The correlation among variables shows that Pb and Cd levels in potato tubers were influenced by the respective soil concentrations. However, no correlation was observed between soil heavy metal content and tuber yield.
