Abstract

Agriculture is an activity of utilizing biological resources by humans to produce food, industrial raw materials with the aim of fulfilling their needs. Chili (Capsicum annuum L.) is a horticultural commodity that has important economic value in Indonesia, so chili cultivation is very attractive to farmers. This study aims to determine the types of insects that are detrimental to chili plants. This type of research is descriptive qualitative research. This research was conducted from 16 December to 12 January 2023. This research was also carried out in the village of Sisarahili Ekholo, Lolowa'u District, Nias Selatan Regency. Identification is one of the ways or actions taken to find out the description of something being studied as a determinant or determination of identity, one example is insects (Insecta). Insects as a component of biodiversity have an important role in agricultural ecosystems, namely as herbivores, parasitoids, predators and environmental bioindicators. Based on the results of the research and discussion, it was found that the research obtained several types of insects, namely green grasshoppers (Atractomorpha), stinging bugs, stem and shoot borer insects (Scirpophaga innotata), green ladybugs (Hemiptera), and caterpillars. Suggestions from researchers are that people should be able to use appropriate techniques in exterminating insects on rice plants, because not all types of insects found on rice plants are harmful but some are beneficial such as: bees, butterflies and dragonflies and several other types of insects .

Abstract

This study aims to explore the influence of local wisdom on soil fertility in South Nias. Local wisdom, which includes traditional agricultural practices such as the use of organic fertilizers, crop rotation, and sustainable forest management, has proven effective in enhancing soil quality and productivity. Through a literature review approach, data were collected from various sources to analyze the relationship between local practices and soil fertility. The results indicate that local wisdom not only improves soil fertility but also contributes to environmental preservation and ecosystem sustainability. These findings underscore the importance of integrating local wisdom into modern agricultural practices to achieve sustainable food security and community well-being in South Nias.

Abstract

This study aims to analyze the influence of soil texture types on land resilience to drought in South Nias, with a focus on the soil's capacity to retain moisture during prolonged dry seasons. The collected data include soil texture types (sand, silt, clay, and loam) and physical soil properties that affect water retention. The results indicate that sandy soils have low water-holding capacity, making them highly vulnerable to drought. In contrast, clay soils, while having high water retention, often face poor drainage issues. Loamy soils, which are a mixture of sand, silt, and clay, demonstrate better drought resilience due to a balanced capacity for water retention and drainage. The study also highlights the importance of soil management strategies tailored to soil texture types to enhance land resilience to drought. These include mulching, drip irrigation, and increasing organic matter content. Based on these findings, the application of more effective soil conservation techniques is recommended to support sustainable agriculture in South Nias.

Abstract

This study explores the integration of modern soil science, integrated farming systems (IFS), and Nias local wisdom to improve agricultural productivity in Desa Bawonifaoso, Kecamatan Teluk Dalam, Kabupaten Nias Selatan. The research aims to examine how combining scientific soil management practices with diversified farming techniques and traditional knowledge can enhance crop yields, environmental sustainability, and community resilience. Using a qualitative literature review approach, data were collected from scientific journals, books, conference proceedings, and credible online sources that discuss soil fertility, integrated farming, and the application of local wisdom in agriculture. The findings indicate that modern soil science interventions such as soil testing, rational nutrient management, and organic amendments can optimize soil fertility and crop growth. When applied alongside integrated farming practices and local wisdom traditions, such as communal land management, crop rotation aligned with cultural calendars, and organic residue utilization, farmers achieve higher yields, reduced dependency on chemical inputs, and improved environmental sustainability. Furthermore, integrating these approaches strengthens community engagement and knowledge transfer, ensuring sustainable adoption. The study concludes that the tripartite integration of modern soil science, IFS, and local wisdom offers a holistic, culturally appropriate, and environmentally sustainable model for agricultural development. It is recommended that agricultural extension programs and policymakers support this integrated approach to enhance productivity, resilience, and food security in rural Indonesian communities.
