Abstract

Application of GA3 and NPK fertilizers is already known to promote growth of plants. Potential effects of GA3 and NPK on the growth of Phalaenopsis ambilis L. orchid were investigated in the present study. However, increasing application GA3 concentrations of 0, 1, 2, 3, 4, 5 ppm/plant and NPK concentrations of 0, 1, 2, 3, 4 gram/plant. The observation started 30, 45, 60, 75, 90 days after application. This research was use the concentration of GA3 and NPK separately (without combination), each treatment showed a significant effect on the number of leaves, stem diameter, leaf area and leaf area index and had no significant effect to plant height variables. Treatment of GA3 (3 ppm / plant) showed positive results on the variable number of leaves, leaf area and leaf area index. Increasing the concentration of GA3 to 5 ppm / plant did not show any significant difference with the treatment of GA3 concentration of 3 ppm / plant. This shows that plants are needed in small amounts. The dose of fertilizer 1 g / plant showed positive results on the variable number of leaves and stem diameter, while for the leaf area variable and leaf area index required higher NPK fertilizer osis ie 2 g / plant. The increase of NPK fertilizer dosage up to 4 g / plant was not significantly different from treatment 1 and 2 g / plant.Keywords: Phalaenopsis ambilis L., GA3, NPK, Growth

Abstract

Ecosystem rice fields that have high diversity, able to control the pest. Habitat entomopathogenic fungi in the soil have been examined on cabbage plants but has not been reported in the rice field. The study was conducted through surveys of crops and paddy fields by the application of IPM in Kasembon Malang. A total of 5 points soil samples were determined diagonally used in this study. Isolation of entomopathogenic fungi from the rhizosphere of paddy is done by plate dilution method. Entomopathogenic fungi were identified to genus level by observing the macroscopic and microscopic characteristics. Koch's postulates done on Tenebrio molitor, then observe the symptoms and mortality of Spodoptera litura time pathogenicity test. The results showed that the genus of entomopathogenic fungi in the rhizosphere of rice is Penicillium sp., Aspergillus sp. and has not been identified. Chemical analysis of soil for pH is 4.00 to 5.00. Soil organic matter is 1.89% to 3.20%. Keywords: diversity, entomopathogenic fungi, integrated pest management, rhizosphere

Abstract

High ecosystem diversity can control pest populations. Rice is a staple food that continues to be researched for interesting things. Indonesia is ranked 3rd for production at the international level. The research was conducted through a survey of plants and paddy fields with conventional application in Kasembon Malang. Standard chemical fertilizer and pesticide application were used in this field. A total of 5 diagonally determined soil sample points were used in this study. The dilution method was carried out for the analysis of entomopathogenic fungi which were then tested using the Koch’s Postulate method on Tenebrio molitor, then observed the symptoms and mortality of Spodoptera litura during the pathogenicity test. The diversity value also demonstrated a medium diversity. We conclude that an application of pesticides and chemical fertilizer according to recommended practices, are not negatively affect the diversity of entomopathogenic fungi. Aspergillus sp and Penicilium sp can cause death against Spodoptera litura.

Abstract

The black ant (Dolichoderus thoracicus) is known as a natural enemy of Hypothenemus hampei Ferr., the Coffee Berry Borer (CBB). The conservation efforts for this natural enemy can be carried out by using ant nest technology with artificial feed. This research explored artificial nesting and feeding methods for black ant colonies in coffee plantations in Jember District, Indonesia, to combat the CBB. Utilizing a Randomized Block Design, the study examines different nest materials and shapes, various artificial feeds, and the influence of environmental factors on ant colony growth. Cocoa leaves are the most effective nesting material, significantly increasing ant populations (11,532 individuals on average) compared to coconut leaves (4,645.83 individuals); no significant impact of nest shape on ant attraction; granulated sugar is the preferred artificial feed. A notable increase in ant populations was observed with a longer nest placement duration of four weeks. Environmental factors, especially humidity and temperature, significantly influence nests' and feed interactions. The study highlights the importance of specific nesting materials and environmental considerations in effective pest management strategies in tropical agriculture, offering a sustainable approach to enhancing coffee plantation productivity.

Abstract

The Silverleaf whitefly, Bemisia tabaci (Hemiptera: Aleyrodidae), is a destructive insect pest of important greenhouse and field crops. Several studies have shown the effectiveness of Beauveria bassiana in controlling Silverleaf whitefly.. However, a major challenge lies in the rapid evaporation of water in greenhouse crop models. Therefore, this study aimed to evaluate the effectiveness of B. bassiana against the whitefly and test its compatibility with various vegetable oils as carrier media. This research at the Agrotechnology Laboratory, Faculty of Agriculture, University of Jember, used pure isolates of B. bassiana for mass production until conidia reached 2.5 x 107 per gram. We employed a Completely Randomized Design (CRD) with factors of vegetable oil (Corn Oil, Vegetable Oil, Soybean Oil) and concentration (5%, 10%, 15%) using Ultra Low Volume (ULV) formulations. The results revealed that the addition of vegetable oils enhanced the effectiveness of B. bassiana in controlling Silverleaf whitefly, with corn oil having the most significant impact due to its high carbohydrate content that supported B. bassiana viability. Additionally, the concentration of B. bassiana formulation also influenced the rate of whitefly mortality (mycocity), with a 15% concentration yielding the best results. Whitefly nymphs infected with B. bassiana exhibited slowed activity and reduced appetite. Adding vegetable oil facilitated the formation of a protective biofilm around conidia, shielding them from UV radiation, increasing conidia viability, and supporting field application. The infection process by B. bassiana required 6 days to achieve 100% mortality. This research suggests that B. bassiana can be an effective alternative for controlling Silverleaf whiteflies, especially when used with plant-based oils as a carrier medium. This approach may help reduce reliance on chemical pesticides and address issues related to Silverleaf whitefly resistance to insecticides.
