Abstract

The decreased soil carrying capacity is due to reduced soil organic matter content, caused by disproportionally larger use of inorganic fertilizers and synthetic chemical pesticides in farming activities than organic fertilizers and environmentally friendly weeds, disease, and insect pests control materials. Reducing the use of inorganic fertilizers and synthetic chemical pesticides could be done by using production facilities of organic agriculture in the form of organic fertilizers and synthetic non-chemical pesticides on a larger scale, which base materials are available in nature. The problem faced by farmers in using these inputs is the lack of awareness and skills in producing organic inputs. This community service program with competitive schematics aims to assist the community in preparing local resource-based organic production inputs in Uwe Nuni Village, Palolo District. Specifically, to increase the awareness and skills of farmers in producing organic inputs based on local resources. The method used for counselling and training is Focus Group Discussion (FGD) approach, as well as practice and demonstration plots, which also provide technical guidance on making compost and botanical pesticides, and organic-based plant cultivation techniques. The results of the community service program show that the implementation of counselling and training increases the community’s awareness, skills, and attitudes by 38%, 56% and 54%, respectively. The compost made during the technology training was made from cow and goat manure, while the botanical insecticides were made from quickstick (Gliricidia sepium) plant leaves, papaya leaves, and soursop leaves. These plants are potential resources in Uwe Nuni Village, Palolo District.

Abstract

Pest and disease attacks are one of the obstacles in increasing shallot production in the Palu Valley, Central Sulawesi. Farmers still rely on the use of synthetic pesticides to control pests and diseases, which results in a high demand for insecticides and fungicides. This community service aims to disseminate pest control technology with the bioinsecticide Beauveria bassiana and disease control with the biofungicide Trichoderma, as well as train farmers to develop and apply it on their farms to solved the problems. The methods applied are training, technology application demonstration plots, coaching, and mentoring. The results of the activity showed that the participants were able to make and develop the bioinsecticide Beauveria bassiana and the biofungicide Trichoderma well. The application of bioinsecticides and biofungicides on demonstration plots reduced the intensity of onion caterpillar attacks and stem rot disease of shallots. With these results, farmers are expected to be able to develop and apply them in their farms.

Abstract

Maize is an important commodity after rice that gets priority in increasing food security in Indonesia. The emergence of Invasive Spodoptera frugiperda pests in Indonesia is a threat to the sustainability of maize production in Central Sulawesi. The use of synthetic insecticides to control these pests has various negative impacts. To reduce the negative impact, botanical insecticides can be used. The problem in the use of botanical insecticides is that farmers do not know the effective plant extract control S. Fugiperda. The community service program aims to accompany farmers to develop the extract of Calotropic gigantea, Vitex negundo, and Ageratum conyzoides. Implementation method with the participatory action program approach with stages: counseling and training, technology design, extract application demonstration, observation of S. frugiperda attack intensity, and community assistance. The results show that farmers can make and apply plant extracts C. gigantea, V. negundo and A. conyzoides. The three types of plant extracts can suppress the intensity of S. frugiperda attacks. Extract C. gigantea suppresses S. fugiperda attacks (6.71% to 4.04% on 35 HST, and 3.35% to 1.7% on 42 HST), Extract V. negundo (6.71% to 4, 62% and 3.35% to 2.43%) and extract A. conyzoides (6.71% to 4.99% and 3.35% to 2.43%). Thus, the three types of plant extracts have the potential as effective botanical pesticides to control S. frugiperda

Abstract

Human activities may influence the diversity of aquatic insects in rivers. This study aims to assess the diversity of aquatic insects and their relation with mercury levels and water quality along rivers located near the gold mine in Poboya, Central Sulawesi. The insects were collected at six locations based on human activity levels. At each site, the mercury level of water was measured using atomic absorption spectrophotometry (AAS). In addition, water temperature, acidity, dissolved oxygen, and total dissolved solids were determined. The study recorded 23 species of aquatic insects belonging to 7 orders and 14 families. Mercury levels in the rivers did not exceed the threshold except at two sites and did not affect aquatic insects’ diversity. The diversity of aquatic insects, however, tends to decrease downstream. The diversity of aquatic insects, particularly the Ephemeroptera, Plecoptera, and Trichoptera orders, tended to be higher at the higher dissolved oxygen sites.
