The cultivation of tobacco is one of users of agro-chemical substances such as insecticides, herbi-cides, defoliants, and fertilizers among other food crops and plants with high economical value. The use of these chemicals may bring negative effects regarding the richness and abundance of arthropods. The study of arthropod community in the Virginia tobacco ecosystem was carried out in Central Lombok, West Nusa Tenggara Province, during the 2010 plantation year. It was aimed at finding the composition, structure, and dynamic of the arthropod diversity around the tobacco field. Samples were obtained by using trapping techniques (pitfall traps, yellow-pan traps, and sweep net). The number of arthropods found in Virginia tobacco field are 69, consisting of 65 species of insects (belonging to 46 families and 8 orders) and 4 species of spiders (belonging to 4 families). The majority of insects found was Hymenoptera, dominated by bees. Based on the ecological functions, the major group of arthro-pods documented was phytophagous (20 species), mostly Coleoptera and Orthoptera. Yet, the number of predators was relatively more abundant than that of the phytophagous. The number of kinds of ar-thropods commonly interacting around the field fluctuated during the growing period, while in the cultivation period the number decreased. The diversity of the species (H) and the ratio of abundance of the natural enemies and phytophagous in the field was high.

ABSTRACT Arthropods found on the surface of the soil and plant canopy that interact with small chili plants, which act as predators, parasitoid, herbivores, scavengers, decomposers, pollinators, and pests. Diversity is a function of stability, the more diverse the arthropods in the plantation ecosystem, the more stable the ecosystem is, and vice versa. The research aims to determine the level of abundance and the diversity of soil the surface Arthropods in small chili (Capsicum frutescens L.) plantations in Kuripan West Lombok. The methods used in this research is descriptive, the observations were made using the pitfall trap when the plant age 45 days after the interval once a week for 10 observations. The finding showed that there were 7 soil surface Arthropods families of family Formicidae 25,68 %, Carabidae 20,39 %, Lycosidae 19,26 %, Araneidae 13,48 %, Oxyopidae 13,32 %, Acrididae 5,30 %, Dan Trigoniulidae 2,57 %. Soil Arthropods diversity (H’) index of 1,8 including low diversity. Keywords : Ecosystem of small chili, Arthropods.

Interventions in the use of technology to farmers as an alternative in Pest Management in potato cultivation are highly expected by farmers in the Sembalun area. Therefore, it is worth trying its utilization on potato crops to control important pests that attack. The method used in this activity is the Action Research Method by applying the Participatory Action Program approach from participants through discussions, and group work on all activities. The results of the group discussion showed that the group members had largely not recognized the types and functions of natural enemies in Potato Pest Management. After joint observations accompanied by the team, participants actually knew the types of natural enemies, both predators, and parasitoids, but they did not know the role of natural enemies in the agroecosystem. After finishing the meeting, the group realized the importance of maintaining the presence of natural enemies of pests in the potato agroecosystem so that the use of pesticides, which had been the main control technique for pests, could be reduced. Thus, it is hoped that the potato farming business in Sembalun will increase profits and produce environmentally friendly products

Salah satu alternatif teknologi pengendalian hama yang cukup menjanjikan untuk dikembangkan adalah penggunaan pestisida nabati yang lebih bercirikan alami daripada ciri kimiawi. Dengan sifat-sifatnya yang mudah terurai, aman bagi kesehatan manusia dan lingkungan hidup, dapat diharapkan bahwa produk-produk pertanian yang diperlakukan dengan pestisida nabati dapat diterima dan berdaya saing tinggi di pasar global. Bahan-bahan nabati dapat diperoleh dari berbagai tumbuhan. Disamping itu, ada beberapa yang dapat diperoleh dari limbah pertanian seperti limbah batang tembakau virginia. Produk pestisida dari bahan limbah tembakau Virginia tersebut telah dihasilkan oleh tim penelitian Fakultas Pertanian Universitas Mataram dengan nama Pestisida Nabati BT., yang telah diuji terhadap hama dari ordo Lepidoptera seperti Spodoptera litura pada tanaman kedelai. Dengan memanfaatkan petisida nabati tersebut diharapkan peranan musuh alami menekan hama akan meninghkat, sehingga penggunakaan pestisida kimia dapat dikurangi. Dengan demikian hasil yang diperoleh akan meningkat secara kuantitatif dan kualitatif dan akhirnya efisiensi dalam proses produksi akan tercapai dan keuntungan petani akan meningkat. Intervensi pemanfaatan teknologi kepada petani sebagai salah satu alternative dalam Pengelolaan Hama, terutama kutu kebul ( Bemisia tabaci) merupakan serangga hama vector penular penyakit virus pada budidaya kentang . Hasil pengabdian menunjukkan bahwa sebenarnya petani kentang sudah mengenal beberapa pestisida nabati dari berbagai bahan baku local,. Petani sangat tertarik memanfaatkan limbah batang tembakau Virginia yang melimpah di pulau Lombok, dan berharap akan mampu menjadi alternative untuk mengurangi ketergantungan penggunaan pestisida kimia di kawasan agrowisata Sembalun.

The outbreak of the COVID-19 pandemic has encouraged people to adopt a healthier lifestyle and at the same time carry out a number of environmentally friendly activities such as urban farming. Besides helping to guarantee the food security aspect of urban areas, urban farming also helps create green open spaces. Even so, urban farming also has a negative impact, if it is carried out with a system that is not wise and effective, such as it can cause increased noise pollution, air pollution, flooding, water wastage, and even potential as a breeding ground for mosquitoes that transmit various diseases. Therefore, it is necessary to educate the public about various aspects needed in the implementation of urban farming, one of which is how to implement Integrated Pest Management (Known as PHT). The method used in this activity is the Action Research Method by applying the Participatory Action Program approach from the participants through discussion, and group work in all activities. The results of group discussions at KWT Bunga Matahari, and other urban farming groups in Kekalek and in Ampenan show that the majority of urban farming communities are very interested in developing various types of fresh vegetables and fruit in their yards as part of the Department of Sustainable Food Home Areas (KRPL) program. Food Security of the Province of NTB and the City of Mataram. Group discussions also revealed that group members became more active during the COVID-19 pandemic, especially during WFH in the early days of the pandemic. They feel the benefits of farming activities in the yard because it really helps meet the family's food needs, especially fresh vegetables. However, most of the target group members are still not familiar with environmentally friendly cultivation techniques, especially in terms of integrated pest management. Although in fact, they are not aware that there are several activities that include PHT, such as monitoring, planting ornamental plants (refugia) around vegetable crops, and mechanical control by directly killing pests that attack their plants
