Insect Diversity in Mina Padi in Purwosari Village, Pematang Bandar, Simalungun, North Sumatra
Introduction
The Mina Padi area in Purwosari Village, Pematang Bandar, Simalungun, North Sumatra, is a region known for its rice fish farming activities. The diversity of insects in this area is a crucial aspect of the ecosystem, playing a vital role in agricultural productivity. This study aims to identify and analyze the diversity of insects in the Mina Padi area, with a focus on the impact of rice fish farming activities on insect populations.
Methodology
The study was conducted between March and July 2016, using purposive random sampling to collect data from the Mina Padi area. Three types of traps were used: yellow trap, sweeping net, and core sampler, each repeated five times. The data collected was then analyzed to identify the diversity of insects in the area.
Results
The results of the study showed that in the Mina Padi area, there were insects from 9 orders, 40 families, and 42 species, totaling 2028 individuals. The Diptera Order, especially the Anopheles species, had the highest number of individuals, with 378 individuals and a relative contribution value (KR) of 18.64%. In contrast, the rice field control area had 9 orders, 36 families, and 40 species, with a total population of 2129 individuals. The Order of Homoptera, especially the Dorsalis Dorsalis species, dominated with 529 individuals and a KR of 24.84%.
Diversity Index
To evaluate the diversity of species, the diversity index (H ') was calculated. The results showed that the fish farming area had a higher diversity index value, with a value of 2.96 in the fourth capture treatment. In contrast, the land control area had a relatively moderate diversity index value of 2.6.
Importance of Insect Diversity
The diversity of insects in the Mina rice environment is crucial for understanding the role of insects in the agricultural ecosystem. Insects play a vital role as pollinators, natural predators, and indicators of environmental health. The dominance of the Diptera Order in the Mina Padi area indicates the potential for the development of insect populations that can contribute to increased rice production. However, the existence of these insects also needs to be considered, as some species can act as harmful pests.
Impact of Fish Cultivation
The high diversity index value in the mina rice area compared to land control shows that the practice of fish cultivation can create an environment that is richer in biological diversity. This can be influenced by the interaction between fish and rice that is mutually beneficial, where fish can control existing pests, while rice plants provide habitats and food sources for insects.
Conclusion
The results of this study highlight the importance of understanding the value of insect diversity in increasing agricultural productivity. The implementation of environmentally friendly aquaculture techniques can help maintain and improve useful insect diversity, while minimizing the negative impacts of pests. With the right approach, the potential of rice mina can be maximized, providing ongoing benefits for farmers and surrounding ecosystems.
Recommendations
Based on the results of this study, it is recommended that farmers and land managers understand the value of insect diversity in increasing agricultural productivity. The implementation of environmentally friendly aquaculture techniques can help maintain and improve useful insect diversity, while minimizing the negative impacts of pests. Additionally, awareness about the importance of biodiversity conservation in modern agricultural practices should be increased, and more sustainable adoption of cultivation techniques should be encouraged in society.
Future Research Directions
Future research should focus on the impact of different aquaculture techniques on insect diversity and the development of strategies to maintain and improve useful insect diversity. Additionally, research should be conducted on the role of insects in the agricultural ecosystem and the importance of biodiversity conservation in modern agricultural practices.
Limitations of the Study
This study has several limitations, including the limited scope of the study area and the use of a single sampling method. Future research should aim to address these limitations and provide a more comprehensive understanding of the diversity of insects in the Mina Padi area.
Conclusion
In conclusion, this study highlights the importance of understanding the diversity of insects in the Mina Padi area and the impact of rice fish farming activities on insect populations. The results of this study provide valuable insights into the role of insects in the agricultural ecosystem and the importance of biodiversity conservation in modern agricultural practices.
