Abstract

Catfish farming is one of the businesses that is very much in demand by the community, because it can improve the community's economy. However, not all catfish farming businesses can produce maximum results. This can be caused by several factors, both from feed, management and water quality. Decrease in water quality can be caused by feces and fish feed residue. Poor water quality can cause the growth process, physiology and level of fish behavior to be disturbed. Efforts that can be done is to use aquatic plants as phytoremediation. The plants used in this study were Azolla sp, Eichhornia crassipes, Lemna sp, Ipomoea aquatic. The design used in this study was a completely randomized design with 4 treatments and 3 replications. The parameters observed in this study were ammonia levels, pH, and plant population. The results showed that Eichhornia crassipes and Lemna sp were able to reduce ammonia levels in catfish cultured water by 0.01 mg/l at the end of the study.Keywords:AmmoniaWater plantsCatfish

Abstract

This study aims to observe the effect of administering AMF on the growth of chili plants and the level of root infection of chili plants. The research was conducted in May–September 2025 using a non-factorial Randomized Block Design (RBD) with one factor, namely the type of AMF consisting of four treatments: without (P0), (P1), (P2) and (P3) each treatment was given at a dose of 16 g of plants⁻1 and three replications. The parameters observed included plant height, number of leaves, number of fruits, and the percentage of root infection by mycorrhizae. The research data were analyzed using analysis of variance, followed by a DMRT test at the 5% level if significant effects were found. The results analysis showed that the application of AMF had no significant effect on the height of chili plants and the number of leaves at the ages of 15, 30, and 45 days after planting. However, descriptively, AMF treatment, especially mixed mycorrhiza treatment, showed a tendency to increase vegetative growth in the final growth phase. The number of chili pepper fruit did not differ significantly between treatments, although Glomus sp. inoculation resulted in the highest number of fruit compared to other treatments. The percentage of root infection increased with AMF application, indicated by the formation of hyphae, vesicles, and arbuscules, indicating the success of the mycorrhizal symbiosis with chili pepper roots. The results of the study showed that the administration of AMF has the potential to increase the physiological efficiency and nutrient uptake of chili plants, although the statistical effect is limited.

Abstract

Sclerotium rolfsii Sacc. merupakan jamur penyebab penyakit rebah kecambah pada tanaman kedelai (Glycine max L.) yang menyebabkan penurunan produksi kedelai. Salah satu upaya untuk meningkatkan ketahanan tanaman kedelai terhadap serangan patogen S. rolfsii adalah dengan menggunakan agen hayati T. harzianum. Tujuan dari penelitian ini untuk mengetahui dosis pelet T. harzianum yang tepat untuk menekan pertumbuhan cendawan patogen Sclerotium rolfsii penyebab penyakit rebah kecambah pada tanaman kedelai. Metode penelitian menggunakan Rancangan Acak Kelompok Non Faktorial (RAK), dengan 6 perlakuan dan diulang sebanyak 5 kali sehingga diperoleh kombinasi perlakuan sebanyak 30 unit tanaman. Data dianalisis menggunakan Analysis of Variance (ANOVA), didapatkan hasil yang berbeda nyata α<0,05 dilanjutkan dengan analisis BNJ 5%. Hasil penelitian menunjukkan T. harzianum dengan dosis 20 gram/tanaman berpengaruh menurunkan intensitas penyakit rebah kecambah yang disebabkan cendawan patogen S. Rolfsii dan masa inkubasi perlakuan yang terserang lebih cepat yaitu pada perlakuan kontrol (VD0), Trichoderma harzianum dengan dosis 10 gram/tanaman (VD1) sedangkan perlakuan yang paling lambat terserang penyakit yaitu perlakuan Trichoderma harzianum dengan dosis 30 gram/tanaman (VD5).
