Abstract

Tanaman cabai rawit (Capsicum annuum L.) merupakan komoditas hortikultura yang banyak dibudidayakan di lahan sawah, namun sering mengalami cekaman genangan air akibat banjir. Upaya untuk mengatasi kendala tersebut yaitu dengan aplikasi unsur hara silika. Penelitian ini bertujuan untuk mengetahui peran silika dalam meningkatkan toleransi cabai rawit terhadap cekaman genangan. Percobaan dilakukan di rumah kaca milik Universal PT Tempu Rejo, Kabupaten Jember, Jawa Timur mulai bulan Oktober sampai dengan Desember 2021. Penelitian dilaksanakan menggunakan rancangan acak lengkap faktorial (4x4) dengan 3 ulangan. Faktor pertama adalah dosis pupuk silika yaitu D0 = 0 mL, D1 = 0.15 mL, D2 = 0.30 mL, dan D3 = 0.45 mL per tanaman. Faktor kedua adalah cekaman genangan yaitu W1 = 50-70%, W2 = >70-90%, W3 = >90-110%, dan W4 = >110-130% dari kapasitas lapang. Hasil penelitian menunjukkan bahwa interaksi antara perlakuan dosis silika dengan cekaman genangan tidak berpengaruh nyata pada peubah tinggi tanaman, jumlah daun dan luas daun, namun berpengaruh nyata pada peubah kadar air relatif, kandungan H2O2, prolin dan klorofil. Pupuk silika mampu meningkatkan ketahanan tanaman cabai rawit terhadap cekaman genangan ditunjukkan dengan korelasi positif antara silika dengan klorofil dan prolin serta korelasi negatif antara silika dengan kandungan H2O2. Kata kunci: fase vegetatif, hidrogen peroksida, klorofil, prolin

Abstract

Red chili consumption in Indonesia is recorded to increase by 6.78% or 40.42 thousand tons in 2024 from 1,650.75 thousand tons in 2022, while productivity in 2025 is projected to increase by 6.78%, while chili productivity in 2024 is 1,386.45 thousand tons. 37% of the land area in the Kesambi Sub-watershed is marginal and has potential for horticultural cultivation. The research aims to align land and chili cultivation management on the slopes of Mount Raung, Indonesia, toward sustainable agriculture and national food self-sufficiency. The method used is through data collection, both laboratory data and land biophysical data that are adjusted to match the suitability with plant growth requirements. The results of the study showed that the actual land suitability of red chili plants at 78.87% or 2,558.48 ha was dominated by the marginally suitable class (S3), and 21.13% or 685.58 ha were in the unsuitable category (N), with the most inhibiting factors being erosion hazards, nutrient retention, and air availability. Efforts to improve land quality to produce optimal production for crop achievement through the addition of agricultural fertilizers such as NPK, the provision of organic matter and dolomite, and slope improvement by making “gulud” terraces or providing mulch so that the potential land was achieved to 67.11% or 2,177.01 ha dominated by class S3, 21.13% or 685.58 ha were categorized as unsuitable class (N), and 11.76% or 381.47 ha were categorized as quite suitable class (S2).

Abstract

The variety of soil macrofauna serves as a biological indicator to assess the sustainability of land, especially in farming areas. Soil macrofauna are essential in the nutrient cycle. Macrofauna significantly contribute to the decomposition of soil litter into organic materials. Environmental factors affect the presence of soil macrofauna. Important environmental factors include soil pH, soil temperature, and soil organic carbon content. Differences in these three factors are directly visible in agricultural lands, particularly between rice paddies and drylands. Rice paddies are actively cultivated and flooded agricultural lands. Meanwhile, drylands are agricultural lands that are not actively cultivated. The author intends to explore the variety of soil macrofauna in two distinct land settings. Additionally, the author seeks to assess how variations in land conditions impact the diversity of soil macrofauna. Samples of soil were collected from eight sites located at elevations between 91 and 600 meters above sea level, which included four rice fields and four dryland areas. The study examined several factors, such as soil temperature, soil pH, soil organic matter, and the biodiversity of soil macrofauna. Soil temperature was measured with a soil thermometer. The soil pH was assessed using a pH meter, while soil organic matter was evaluated with the Walkey and Black technique. Observations of soil macrofauna were carried out employing hand sorting and the Berlesse funnel extraction method. The biodiversity of soil macrofauna was determined using the Shannon's Weaver Diversity Index and the Margalef Species Richness Index equations. The findings indicated that soil temperature varied from 23.47 to 27.60 degrees Celsius, soil pH varied from 4.65 to 6.72, and the percentage of soil organic matter ranged from 1.66 to 3.62%. These three elements displayed a negative relationship with the diversity of soil macrofauna, while positively correlating with the richness of soil macrofauna species.
