dc.description.abstract | The rice crop system, the
main food commodity for the Indonesian population with a production of around
54.75 million tons of milled dry grain (MDG) with a harvest area of 0.45 million
hectares or an increase of 40.87 thousand hectares (0.39 percent) compared to
2021. Rice production is strongly influenced by cultivation, planting varieties and
pest and disease attacks on rice plants. This study aims to inventory insect
diversity in Hamparan Perak Village, Hamparan Perak District, Deli Serdang
Regency, North Sumatra from April to July 2023.This study used Purposive
Random Sampling with 4 variations of sap, namely rubber sap (Hevea
brasiliensis), jackfruit sap (Artocarpus heterophyllus), papaya sap (Carica
papaya), and Jatropha curcas sap with Hazton planting system. The results
showed that insects caught on land using rubber latex (H. brasiliensis) were 2397
spesies, the most of the three other latex other with 8 orders and 29 families, while
the lowest was using jatropha sap (J.curcas) (8 orders, 29 families, 1159 spesies).
As for the calculation of the diversity index (H'): (H'gk=2.98, H'gn=1.88,
H'gp=3.30, H'gj=3.27), Species Richness Index ((R'): (R'gk=7.78, R'gn=7.73,
R'gp=7.10, and R'gj=7.05), and Index of Evenness (E'): (E'gk=0.88, E'gn=0.55,
E'gp=0.98 and E'gj=0.97). The status of insect functions identified on the land
using the five gums as many as 5 types, namely herbivores, pollinators, predators,
parasitoids and scavengers. | en_US |
