Abstract

Macrosiphoniella sanborni is a main concern in the production of ornamental chrysanthemum plants. Farmers commonly use chemical treatment to control aphids, but this can harmful the environment and humans. Therefore, alternative environmentally control is needed, one of which is by using botanical pesticides such as Azadirachta indica and Barringtonia asiatica. This research aimed to test the effectiveness of the neem and bitung seed extract against M. sanborni pests on chrysanthemum plants. This research was conducted at the Chrysanthemum cultivation Mr. Syarif’s screen house in Karyawangi village, Parongpong district, West Java, which began in January 2021 to May 2021. This research used an experimental method using a Randomized Complete Block Design (RCBD) which each experiment consisted of 10 treatments and each treatment was repeated 3 times. The tested treatments are neem and bitung seed extract in different concentration, and controls. The results of this study revealed that the effective treatment of M. sanborni on chrysanthemum is the extract of bitung seed at the concentration of 2%. Bitung seed extract pesticides can be used as an alternative synthetic pesticide to control population of M. sanborni.

Abstract

Strawberry production is often decreased by plant pest infestation in the field. One of the major pests is Aphis gossypii. Strawberry farmers typically use synthetic chemical pesticides to control aphid, however, this can pose serious environmental and human health problems if done continuously. The use of synthetic chemical pesticides can be minimized by using botanical pesticides, as they are safer for human health and the environment. Botanical pesticides that can be used include neem seed extract (Azadirachta indica) and sea poison tree (Barringtonia asiatica). The objective of this research was to test the effectiveness of neem and sea poison tree seed oil formulations against A. gossypii on strawberry plants. The experiment was conducted at CV Bumi Agro Technology, Lembang, from April 2023 to August 2023, arranged in the randomized complete block design consisting of 7 treatments with 4 replications. The treatments were application of neem and sea poison tree seed oil at different concentrations, as follow: (A) Control, (B) Abamectin 0.15%, (C) Neem Oil 2%, (D) Neem seed oil 50 EC 2%, (E) Neem seed oil 50 EC 1%, (F) Sea poison tree seed oil 30 SC 2%, and (G) Sea poison tree seed oil 30 SC 1%. The results showed that neem and sea poison tree seed oil formulations at the concentration of 2% were effective in controlling A. gossypii on strawberry plants.

Abstract

The development of plant cultivation technology is now developing rapidly. One of the technologies being developed is the technology of cultivating landless or by using a hydroponic system. Many types of hydroponics, one of which is the method of drip irrigation with planting media in the form of husk charcoal. The purpose of this activity is to introduce renewable technology to the cultivation of tomato plants to the community, so that public knowledge will increase. This activity was carried out in Parentas Village, Cigalontang District, Tasikmalaya District, with a survey method and socialization of the introduction of tomato cultivation technology through the Hydroponic system to the public. This program succeeded in informing the villagers about the cultivation techniques of tomato plants using Hydroponic technology with satisfactory results. The response of the extension participants who were enthusiastic and felt interested in the technology encouraged the participants to be willing to cultivate tomato plants with Hydroponic technology and work together to be able to produce tomato products with the technology in a sustainable manner.

Abstract

Mango is one of the primary fruit export commodities in Indonesia. The productivity of mango can be increased by controlling the pest population, including fruit flies Bactrocera spp. Various efforts to control the population of fruit flies have been carried out, either by implementing traditional methods or by using synthetic pesticides. However, synthetic pesticides can cause pollution, and therefore we need to control the fruit flies’ population by using the most effective fruit fly trap mode. The study was conducted in the mango yield (monoculture) of Department of Agriculture in Majalengka. The traps in this study were modified Steiner traps with funnels, modified Steiner traps without funnels, bottle traps with funnels, bottle traps without funnels, and modified gypsy moth traps. Each trap was fed with 0.2 ml of Methyl eugenol dripped on a cotton roll and hung in the trap. The results showed that the number of fruit flies caught in each trap every week is significantly different. The highest number of fruit flies caught in each trap every week was achieved by bottle traps without funnels that caught 135 flies, while the lowest number of fruit flies caught was recorded by the gypsy moth traps with 16 flies. The transparent color of the bottles and a large number of holes effectively lured the fruit flies into the bottle traps without funnels.

Abstract

Chili plants are highly susceptible to infestations by various Plant Pest Organisms (OPT) such as fruit flies, thrips, leaf-eating caterpillars, and fruit borers, as well as diseases like anthracnose, root rot, and leaf spot. To manage these threats, most farmers still rely on synthetic chemical pesticides. Improper pesticide application—particularly in terms of dosage and frequency—can lead to pesticide residues on harvested crops and pose risks to both the environment and human health. This study aims to analyze farmers' behavior in pesticide use and to measure pesticide residue levels in chili samples collected from three major production centers in West Java: Arjasari, Lembang, and Garut. A mixed-method approach combining qualitative interviews and quantitative High-Performance Liquid Chromatography (HPLC) analysis was used to evaluate six active pesticide ingredients. The results showed that most farmers applied pesticides beyond the recommended dosage and frequency. Residues of chlorothalonil and broflanilide were detected in the samples, with concentrations exceeding the Maximum Residue Limits (MRLs). These findings highlight the urgent need for education and stricter oversight regarding pesticide application practices among farmers.
