Abstract
Pepper (Piper nigrum L.) is a superior plantation commodity that has high economic value and the potential to increase foreign exchange. Pepper commodities need to be rejuvenated and control measures and efforts to mitigate pests comprehensively so that they do not become a source of inoculum that can threaten the stability of land productivity. The objective of this research is to determine the diversity index of insects in pepper plantations in Banjarnegara, Central Java. Sampling using purposive sampling technique using a sweep net. The field used for the research consisted of 3 fields and 3 sampling sites per field. The observation was carried out every 2 weeks from May 2024 to July 2024. Arthropods are caught by swinging the net. The net is swung 10 times to the right and left while moving forward 10 steps. The collected data will be analyzed using the Shannon-Weiner (H^) diversity index formula. The Shannon-Wienner diversity index of arthropods in 3 pepper fields in Banjarnegara at the first, third, fifth, and ninth weeks have medium diversity. The dominant arthropod found in 3 pepper fields in Banjarnegara are natural enemy (Diaditus, Iridomyrmex, Micrargus, Anoplolepis, and Oxyopes)- Pest but are not major pest of pepper (Leptocorisa, Microtechnites, and Drosophila)- and other (Cricotopus).
