Therefore, it is necessary to make efforts to improve understanding and practice of cultivation as well as guarantee the quality of the food produced, among others by carrying out socialization "how to register horticultural products in urban areas to obtain a Prima3 certificate" as a guarantee that it is safe for consumption. The method used in this activity is the Action Research Method by applying the Participatory Action Program approach from the participants through discussions, and group work in all activities. The results of the activity show that one of the efforts to improve food safety for business actors of Fresh Plant-Origin Food (PSAT) is by registering for food safety certification. Based on survey results from 6 survey locations, 5 of them are still active, namely Japri Farm, UD Rohana and KWT Bunga Matahari, UD Sari Melanting, and UD Sumber Sari. While 1 other location is not active, namely KP. Petemon Asri. There are several business actors in the City of Mataram who have not extended the registration of the commodities they produce. These actors include the Bijak Sari Poktan, the Farmer Family Farmers Group, Japri and Mataram Hydroponics. The results of the demonstration plot showed that the use of liquid organic fertilizer was able to grow lettuce plants well. The best use of vegetable pesticides is demonstrated by plant-based pesticides extracted from papaya leaves. Botanical pesticides are pesticides whose active ingredients come from plants or herbs and other organic materials that can control pest attacks on lettuce plants, both as repellents, antifedans, attractants.

The study has involved 20 women participating in cattle fattening activities and was conducted by survey using prepared questionnaires, Focus Group Discussions (FGD) and in-depth interview. The study founded that there is impact of intervention on forage and cattle production system. The intervention stimulates farmers to plant Leucaena on their own lands. Farmers are also stimulated to fatten cattle in pens near their houses. Distance of Leucaena plantation to farmer house is relatively close. The short distance encouraged women to cut and carry Leucaena forages. 87% of Sumbawanese women and 63% of West sumbawanese women involved in the training in planting and management of Leucaena. In Sumbawa district, women participation increased from 42% to 100% in collecting feeds. In West Sumbawa, the participation increased from 8% to 45%.All respondents participate in the decision-making process. The decisions include time to sell cattle, selling price and use of money from selling cattle. The change of production system from extensive to cut and carry system and the availability of forages (Leucaena) close to the house has increased women participation. As a result, the workload of men has now been shared with women so male farmers can have more time to do off farm work or simply enjoy free time.

The short distance encouraged women to cut and carry Leucaena forages. 87% of Sumbawanese women and 63% of West sumbawanese women involved in the training in planting and management of Leucaena. In Sumbawa district, women participation increased from 42% to 100% in collecting feeds. In West Sumbawa, the participation increased from 8% to 45%.All respondents participate in the decision-making process. The decisions include time to sell cattle, selling price and use of money from selling cattle. The change of production system from extensive to cut and carry system and the availability of forages (Leucaena) close to the house has increased women participation. As a result, the workload of men has now been shared with women so male farmers can have more time to do off farm work or simply enjoy free time.

The dynamics of Arthropod diversity and abundance in rice field ecosystem in Central Lombok, Indonesia. Biodiversitas 21: 5850-5857. Arthropods have roles as pests, decomposers, pollinators, and natural enemies of pests. Natural enemies play a vital role in pest population control by predation or parasitism. A study of the arthropod community in the rice field ecosystem was conducted in Central Lombok, Indonesia from December 2009 to March 2010 in order to elucidate the composition, structure, and dynamic diversity of arthropods present. Arthropod sampling was done by pitfall traps, yellow pan traps, and insect net. Arthropod dynamic diversity, especially of natural enemies, was determined by diversity index, dominance index, evenness analysis, and pictorial analysis. Based on taxonomical perspective, as many as 98 arthropod species were found, including 85 insect species from 59 families and 9 orders; and 13 spider specie...
