Seeing the bright prospects of cacao plants with the available land potential in Banggai Regency, it is necessary to assess land suitability in the development of cacao plants to know the actual potential land suitability level and the limiting factors that affect the potential for cacao plant development, apart from that it can optimize land use in the area, Banggai Regency. The approach used as an indicator for determining the land suitability class for cacao plantations in Banggai Regency is to take an FAO parametric index land quality based on land characteristics that match the requirements for land use for cacao plants, then tabulated into land map units. The results show that the actual land suitability class of Banggai Regency is N = not suitable and S3 = marginally suitable, with the limiting factor of water availability, root media, nutrient retention, available nutrients, and erosion hazard. So that land improvement efforts are needed to increase the land suitability class by considering the existing potential. Improvement efforts that can be done include adding lime, fertilizer, and organic matter, making mound terraces, bench terraces, credit terraces, and erosion-retaining plants. So that the results of the potential land suitability class are S1 = very suitable, S2 = suitable, S3 = marginally suitable, with an area of land that can be developed for cacao plants in Banggai Regency, namely 419,236.9 ha.

The existence of semi-natural habitats around agricultural land has the potential to support ecosystem services by providing resources for beneficial insects. The study aimed to analyze the abundance, diversity index, and evenness of the insects visiting cayenne flowers. This research was carried out in cayenne cultivation areas in the Banggai Regency. Sampling locations were divided into two categories: cayenne fields close to and far from forests or semi-natural habitats. Insect collection was carried out from June 2022 to August 2022, in the morning and evening, using insect nets. The results showed that 16 families and 52 cayenne flower-visiting insects were identified. Lasioglossum sp.3, Lasioglossum sp.5, Megachile sp.2, ?Parancistrocerus sp. and Rhynchium sp. have a higher abundance than the others. The highest Shannon and Wiener diversity index was found in cayenne fields in Tolisu Village (H'= 2.491), Mansahang (H'= 2.216), Salodik (H'= 2.145), and the lowest in cayenne fields in Kembang Merta Village (H'= 1.211), Dale-Dale (H'= 1.112 ), and Beringin Jaya (H'= 1.149 ). The highest evenness index (E) was found in the fields in Lembah Makmur Village (E= 0.9721) and Mansahang (E= 0.9172), and the lowest was found in cayenne fields in Petak Village (E= 0.3975) and Lenyek (E= 0.4405). The highest species richness was found in cayenne fields in Tolisu (14 species), Salodik (14 species), and Petak (12 species). Cayenne fields in the three villages are close to semi-natural habitats. Our findings show that agricultural land adjacent to semi-natural habitats has increased the species richness of cayenne flower visitor insects. Thus, semi-natural habitats are critical to sustaining insect communities in agricultural landscapes.

Fusarium wilt disease can cause damage and reduce the yield of shallot. Trichoderma sp is a biological agent that can be used to reduce the incidence of fusarium wilt disease in shallot. This study aims to determine the effect of Trichoderma sp on the intensity of fusarium wilt attack and shallot production. This research was conducted in Salodik Village, Luwuk Utara District, Banggai Regency, using a non-factorial randomized block design consisting of five treatments with four replications, namely: P0 (Control), P1 (10 gr Trichoderma sp./liter of water), P2 (12 gr Trichoderma sp./liter of water), P3 (14 gr Trichoderma sp./liter of water) and P4 (16 gr Trichoderma sp./liter of water). The results showed that giving Trichorderma sp had a very significant effect on the average intensity of fusarium wilt disease and had a significant effect on the average production of shallot. The provision of 10 gr Trichorderma sp /liter of water is the best treatment to reduce the intensity of fusarium wilt attack and increased the average production of shallot.

Landscape management in an agroecosystem is part of an ecological approach aimed at conserving biological control to suppress the abundance of pests and crop damage. This study investigates how agricultural landscape composition influences the abundance and attack rates of Spodoptera frugiperda and its parasitoids’ abundance and parasitism rates. The research assessed landscape characteristics in maize fields around Bogor, including class area (CA) and the number of patches (NP) of agricultural and semi-natural habitats. A 300-meter radius buffer was used to evaluate these features. Eggs and larvae of S. frugiperda were collected and reared in the laboratory to observe their parasitized and non-parasitized development. The influence of landscape composition on the abundance, attack rate, and parasitism of S. frugiperda was analyzed using generalized linear models. The results indicate that landscape composition affects the abundance and attack rate of S. frugiperda and influences the abundance and parasitism rate of parasitoids. Increasing the agricultural class area can increase the abundance of S. frugiperda larvae. In addition, increasing the NP and CA of semi-natural habitats can reduce the infestation rate of S. frugiperda. The elevation of maize areas also shows an influence on the abundance of parasitoids and the parasitism of larvae. In contrast, the age of the maize affects the abundance and attack of S. frugiperda. These findings highlight the importance of landscape composition, particularly the presence of semi-natural habitats, in managing pest populations effectively. This ecological approach offers valuable insights for sustainable pest control strategies in agricultural practices.
