Abstract

The cowpea weevil (Callosobruchus maculatus) is a primary pest of stored legumes. It causes economic losses, necessitating control measures to suppress its population. Typically, synthetic insecticides are used for pest control, but their continuous use can harm the environment. This study aimed to determine the optimal dosage of a botanical insecticide derived from Melia azedarach leaves to enhance its toxicity against the cowpea weevil during green bean storage. The experiment was conducted at the Plant Pest Organism Laboratory, Faculty of Agriculture, UnsikaKarawang. A Completely Randomized Design (CRD) was employed, with treatments including P0 (botanical insecticide 0 g/100 g), P1 (botanical insecticide 15 g/100 g), P2 (botanical insecticide 20 g/100 g), P3 (botanical insecticide 25 g/100 g), P4 (botanical insecticide 30/100 g), P5 (botanical insecticide 35 g/100 g), and P6 (carbosulfan insecticide 2 g/100 g). The treatments were directly applied to green beans. Parameters observed included temperature, humidity, daily mortality, and seed weight loss. The results showed that the 35-gram Melia azedarach leaf insecticide achieved 85% mortality on the 7th day and minimized seed weight loss by 0.15 grams. Thus, the 35-gram botanical insecticide effectively controls the cowpea weevil (Callosobruchus maculatus) and reduces its population. Keywords : callosobruchus maculatus, mortality, seed weight.

Abstract

Pakcoy (Brassica chinensis L.) is one type of vegetable that has many benefits, and this plant is one of the commodities with high economic value. Pakcoy plant production is still low because Indonesian people have not cultivated it much because there are several obstacles faced, one of which is soil fertility. In general, to overcome soil fertility, farmers usually only apply inorganic fertilizers. The main purpose for applying inorganic fertilizers is to increase the availability of nutrients quickly in the soil so that it can meet the nutrient needs of plants, but by applying inorganic fertilizers it cannot improve the physical and biological properties of the soil, and when using inorganic fertilizers it can damage the soil. The purpose of this study was to determine the growth response of pakcoy plants to the application of fruit waste POC. The research was conducted in the experimental garden of the Department of Agroindustry, Padang State University in Sijunjung Regency with an altitude of ±450 meters above sea level. This research was conducted in April  - June 2023. The design used in this study was a Randomized Group Design (RAK) with 4 treatments and 6 replicates totaling 24 experimental samples. The treatments given in this study were P0 control (without treatment), P1 150 ml/L water POC fruits, P2 250 ml/L water POC fruits, P3 350 ml/L water POC fruits. The research data were analyzed using anova table 5% and continued with DMRT further test. The parameters observed were plant height, number of leaves, leaf width, stump diameter, and wet weight. Based on the results of the research on the growth response of pakcoy (Brassica chinensis L.) plants to the application of liquid organic fertilizer (POC) fruits, it can be concluded that the P2 treatment (250 ml / plant) produces the highest average value in plant height growth which is 28 cm, the number of leaves is 23 strands, leaf width is 9 cm, the diameter of the stem is 20 cm, and the wet weight of the plant is 138 grams. While the lowest average value is in the P0 treatment (without giving POC / control) which produces plant height growth of 24 cm, the number of leaves is 15 strands, the width of the leaves is 7 cm, the diameter of the stem is 18 cm and the wet weight of the plant is 87 grams. Keywords: growth, pakcoy, poc, fruit waste, organic

Abstract

Curly red chili production has decreased due to disease attacks, one of which is fusarium wilt disease caused by Fusarium sp. fungus. This disease can cause significant losses, even crop failure. Control using chemical fungicides often has a negative impact on the environment and consumer health, so safer alternatives are needed. This study aims to evaluate the effectiveness of Gliocladium sp. dosage as a biological control agent against Fusarium wilt disease in curly red chili plants. This study used a completely randomized design (CRD), with treatments A (control), B (30 grams of Gliocladium sp./polybag), C (60 grams of Gliocladium sp./polybag), D (90 grams of Gliocladium sp./polybag), E (120 grams of Gliocladium sp./polybag), F (180 grams of Gliocladium sp./polybag). The parameters observed were growth percentage (%), attack intensity (%), plant height (cm), number of fruits per plant (fruit), and fruit weight per plant (gram). The results of the effect of Gliocladium sp. to control fusarium wilt disease in curly red chili plants (Capsicum annum L.) concluded that the application of Gliocladium sp. has a significant effect on the growth and yield of curly red chili plants (Capsicum annum L.). Doses of 60, 120 and 180 grams per polybag proved effective in increasing the percentage of plant growth to 100% and suppressing the intensity of disease attack to 0%, showing the potential of Gliocladium sp. as an effective biological control agent. Although the effect on plant height was not statistically significant, there was an increasing trend with the best result at 120 grams per polybag (39.3 cm). Plant productivity also increased, indicated by an increase in the number of fruits per plant (optimal at a dose of 180 grams per polybag with 16 fruits) and fruit weight per plant (highest at a dose of 60 grams per polybag with 45 grams). Keywords: gliocladium sp., fusarium wilt disease, curly red chili

Abstract

Coffee beans are covered in a hard shell so they take a long time to germinate. The length of germination time will affect coffee growth and production. To speed up the germination of coffee beans, growth regulators can be used. Apart from that, the growth of coffee plants can also be influenced by the planting media used to live and obtain nutrients. This research used a Complete Randomized Block Design (RAK) with 2 factors and 3 blocks to obtain 36 research plots. Factor 1: soaking time for growth regulators in Moringa leaf extract (T) consisting of 4 levels: T0: 0 hours, T1: 6 hours, T2: 12 hours, T3: 18 hours. Factor 2: The combination of planting media denoted by (M) consists of 4 levels: M0: topsoil, M1: topsoil + rice husk charcoal + goat dung (2:1:1), M2: topsoil + charcoal rice husks + chicken manure (2:1:1). The research results showed that the soaking time for the growth regulator, Moringa leaf extract, did not have a significant effect on the root length of Robusta coffee plants, but the combination of planting media had a significant effect on the root length of Robusta coffee plants. Keywords : robusta coffee, live and obtain nutrients, moringa leaf
