Abstract

Pertumbuhan penduduk di Kabupaten Banggai mendorong kebutuhan peningkatan produksi pangan yang berkelanjutan, sehingga diperlukan kajian mengenai daya dukung lahan terhadap tanaman pangan utama. Penelitian ini bertujuan mengidentifikasi komoditas pangan unggulan serta menilai kapasitas lahan pertanian dalam mendukung swasembada pangan daerah. Metode yang digunakan adalah Location Quotient (LQ) dan Shift Share Analysis (SSA) untuk menentukan komoditas unggulan, serta analisis daya dukung wilayah berdasarkan perbandingan jumlah penduduk dengan tingkat produksi pangan optimal. Hasil penelitian menunjukkan bahwa jagung, padi sawah, padi ladang, kedelai, kacang hijau, ubi kayu, dan ubi jalar merupakan tanaman pangan unggulan di Kabupaten Banggai. Namun, hanya padi sawah (nilai daya dukung 2,8; terdapat di 6 kecamatan/26,1%) dan jagung (1,7; terdapat di 13 kecamatan/56,5%) yang menunjukkan nilai LQ > 1, sehingga berpotensi mencapai swasembada pangan. Komoditas lainnya memiliki daya dukung relatif rendah (LQ < 1), sehingga memerlukan perhatian strategis dari pemangku kepentingan untuk memperkuat kapasitas produksi. Temuan ini menegaskan pentingnya pengembangan padi sawah dan jagung sebagai prioritas utama dalam pencapaian swasembada pangan di Kabupaten Banggai.

Abstract

The introduction of flowering plants into agricultural landscapes can significantly impact host-parasitoid food webs, although the extent of these effects varies depending on landscape characteristics. This study examined the effects of habitat manipulation by introducing flowering plants on the complexity of herbivore-parasitoid food webs in agricultural landscapes. Using Shannon diversity, links per species, linkage density, and vulnerability, we assessed the effects of flowers planted in maize fields. Herbivore collections were conducted at 2, 4, 6, 8, and 10 weeks after planting. Bipartite network analysis identified nine host morphospecies (Lepidoptera) in maize fields, revealing eight morphospecies in fields without flowering plants and six in fields with flowering plants. Eight major parasitoids were recorded, with Paratetracnemoidea sp.1 and Telenomus remus dominating fields without flowering plants, whereas T. remus was the most prevalent in fields with flowers. Spodoptera frugiperda emerged as the dominant host in both fields, whereas Lymantriidae sp.2 was present in low numbers in both field types. These results indicate that flowering plants enhance Shannon diversity and linkage density. However, the composition of the surrounding landscape can obscure these benefits, leading to simplified food web structures as the agricultural fields expand. Our findings underscore the significance of landscape context in shaping crop-herbivore-parasitoid interactions, offering valuable insights into sustainable agricultural management practices.

Abstract

Soil chemical analysis is the measurement and evaluation of the chemical components present in soil. This study aims to examine the effect of differences in land use on soil chemical properties. This research was conducted from May to July 2024 in South Batui District. Soil sampling locations were based on land use, namely food crops, horticulture, and plantations. The data used in this study were analyzed through laboratory analysis and then processed using Microsoft Excel 2013. The results of this study are that the chemical properties of the soil in several land uses in Batui Selatan District have a significant effect on several soil chemical properties including C-organic and N-total. Meanwhile, for other soil chemical properties pH, P2O5, K-Total, CEC and KB do not have a significant effect on the use of chili, corn and cocoa land. This is influenced by different land management in each land use. Land use in Batui Selatan District is not optimal, because farmers do not clearly understand the needs of plants in each location. To increase soil fertility in various types of land uses, there are several ways that can be done including the addition of organic materials, the use of appropriate fertilizers (both organic and inorganic), proper soil processing, improvement of drainage and irrigation systems, and the application of diverse planting patterns (crop rotation).
